    [0002] MOBILE MODULE FOR THE LIFTING OF TELESCOPIC TOWERS AND THE LIFTING PROCEDURE OF TELESCOPIC TOWERS
    [0003]
    [0004] FIELD OF THE INVENTION
    [0005]
    [0006] The present invention relates to a mobile module for lifting telescopic towers, for example telescopic concrete and / or metal towers. Its main application sector is the construction industry, especially in tower assembly, and more specifically telescopic towers.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] High-rise tower structures, such as those commonly used for wind turbine support, are often constructed using precast reinforced and / or prestressed concrete segments, which are subsequently transported to the installation site, where they are hoisted by a crane and assemble in its final position. In the case of towers of circular cross-section, each vertical section is generally assembled from connected segments or segments. The lower section of the assembly tower is erected first, after which the successive sections are lifted on it, which are lifted in their final position using a crane. Sections are usually pre-mounted at ground level although, alternatively, the segments of a particular section can be hoisted separately and then assembled at the top of the previous section. As a final step in the installation procedure, the upper section is hoisted supporting the assembly formed by the generator and the rotor of the wind turbine.
    [0011]
    [0012] The towers for wind turbines can reach heights of the order of 100-150 m, supporting generation units capable of producing powers of the order of up to a dozen megawatts. The traditional construction techniques of these towers require that the tower segments be lifted using large cranes, which must have lifting heights of at least, the total height of the tower structure itself. The generator unit, which can weigh up to 200 tons, must also be lifted to its final position at the top of the structure. To this end, cranes that can safely lift these weights to such heights are very large and expensive, and the process of transporting such a crane to the installation sites, as well as its installation, is a complex task that requires specialized personnel, heavy machinery and, often, the construction of roads to allow transport of the different elements that make up the tower. These complications are also reproduced during maintenance and repair work on the tower, after installation.
    [0013]
    [0014] Patent application WO 2009/010771 A2 describes a method of lifting a telescopic tower in which several prefabricated telescopic sections of a tower are mounted together horizontally at ground level. Said telescopic sections are hoisted together in an upright position, either by means of a crane or by lifting each section against its outer neighbor section, using an arrangement of support elements and extendable connectors such as motorized jacks. In the lifting method described in said application, each vertical section is supported nested in its contiguous outer section, so that the wall elements form an additional support wall that covers the inner surface of each outer tower section.
    [0015]
    [0016] The hoisted tower method described in WO 2009/010771 A2 suffers, however, from the following disadvantages. First, the method is based on the support of a flange at the bottom of each tower section, on a projection at the bottom of the inner section. This implies that the sections must be hoisted in a specific order, since each successive inner section rests on its neighboring outer section. Second, the method of WO 2009/010771 A2 is excessively laborious, since it involves the construction and subsequent disassembly of an entire interior wall structure (which is almost as large as the tower itself), which can have a serious impact in the speed of the tower construction. Third, the described method is only suitable for structures in which all the walls of all sections of the tower are substantially parallel.
    [0017]
    [0018] As an alternative to the method proposed in the application WO 2009/010771 A2, improved lifting procedures have been proposed, such as that described in the international patent application WO 2011/006526 A1. This procedure is based on a plurality of telescopic sections, arranged at ground level substantially coaxially, with a more internal section and one or more sections arranged around said innermost section, forming telescopic sections that make up the total length of the tower . To fix some sections to others, an adjustment stage is carried out through a plurality of interconnection tendons. lower and upper of said telescopic sections, where tension is applied to said tendons by means of hydraulic jacks, so that the weight of the house section rests on the upper lifting points of the adjacent section, and the sections are raised as it is performed the tension on the said connection tendons.
    [0019]
    [0020] Although the alternative described in WO 2011/006526 A1 allows to improve the installation processes of traditional telescopic towers, it still has important problems not solved in the state of the art, mainly related to the complexity of the pre-installation stages and with Lifting times of tower sections. More specifically, the invention described in said application comprises a first phase of installation of the tendons in each of the telescopic sections, and some later phases in which the hydraulic jacks are connected and released to one or the other cables, to carry out the different hoists for the complete elevation of the tower. However, this approach implies the necessary dilation of the pre-installation and hoisting times, since it requires a previous task of placing the loose cables, and a subsequent task to connect the hydraulic jacks to said cables. In addition, for each of the different lifts that a tower may consist of, the hydraulic jacks must be released from some cables and connected to others, with the corresponding increase in work, time and risk, as these connection points are delicate and of great responsibility.
    [0021]
    [0022] In order to solve this and other problems inherent in the prior art, the present invention aims to provide a mobile module and a lifting method that allows the tower sections to be mounted without a crane, or with the use of a small crane of substantially equal size to that of a tower section, where said method comprises lifting tower sections much faster and more efficiently than with known techniques, also allowing the use of tower sections having walls not parallel
    [0023]
    [0024] BRIEF DESCRIPTION OF THE INVENTION
    [0025]
    [0026] The present invention provides a mobile module for lifting telescopic towers and their corresponding lifting procedure for telescopic towers, said towers being preferably concrete and / or metal, which allows optimizing the lifting process thereof.
    [0027] It is also the objective of the present invention to provide a system that allows reducing the number of operations to be performed during said procedure, so that the most complicated processes are avoided and costs, terms and risks are reduced.
    [0028]
    [0029] With the proposed invention, the operating time is also reduced and the entire process is streamlined, allowing to reduce both the lifting time of the towers, which means significant operational and economic savings. In addition, bearing in mind that wind farms usually comprise a high number of towers, the present invention qualitatively improves the capacity and facility for the recovery and reuse of lifting means and equipment in the different towers of a park.
    [0030]
    [0031] The objectives described above are achieved by a mobile module for lifting telescopic towers, preferably wind towers, in which an ascending section of the tower is raised in relation to a support section of the tower immediately outside, where said mobile module comprises , advantageously: - At least one hydraulic jack.
    [0032] - At least one lifting cable pre-installed through the hydraulic jack and remaining connected to the jack throughout the entire lifting procedure of the telescopic tower.
    [0033] - Grouping means arranged at the free end of at least one lifting cable.
    [0034]
    [0035] Also, during lifting of the tower, the mobile module is provisionally fixed to the head of the support section, and the grouping means are provisionally fixed to the base of the ascending section.
    [0036]
    [0037] More specifically, the object of the invention is carried out by means of a mobile module for lifting telescopic towers and a method of lifting telescopic towers according to the claims herein.
    [0038]
    [0039] The fact that the hydraulic jack and lifting cable are conveniently and permanently integrated into a single mobile device throughout the entire lifting procedure of the telescopic tower, together with the grouping means arranged at the free end of at least one cable raised, they represent a key aspect of the present invention, since they allow, unlike previous inventions, to avoid the successive and numerous operations of pre-positioning of loose cables and connection and release of hydraulic jacks and cables facilitating and speeding up all the process and improving its reliability. In this way, the module described here allows, during its application, to carry out in a single stage the positioning steps of the lifting cables and the elevation of each section, with optimum reuse of the cables for different lifts and without mediating any operation of connection / disconnection between the lifting cables and the lifting jacks.
    [0040]
    [0041] Also, the mobile module can be easily moved to be placed in the different positions established for lifting the different sections of the tower. In addition, said module moves at all times in one piece, that is, only one movement between lifting phases is necessary, achieving a great improvement in agility and economy. This characteristic differs totally from the solutions known in the state of the art, where the elements must be mobilized one by one, which implies a great advantage of the present invention with respect to the current state of the art.
    [0042]
    [0043] Additionally, the objectives described above are achieved by a telescopic tower lifting procedure that employs a mobile module according to the present invention characterized in that it comprises the steps, performed in any technically possible order:
    [0044] - Place the lifting module on the head of a support section.
    [0045] - Fix the lifting cable at the base of an ascending section, using the grouping means.
    [0046] - Pick up the lifting cable with the hydraulic jack and, in this way, lift the ascending section.
    [0047] - Fix the base of the ascending section raised to the head of the support section. - Release the grouping means from the base of the ascending section.
    [0048] - Release the mobile module from the head of the support section.
    [0049]
    [0050] Said mobile module may also comprise at least one cable guide structure that allows the guide of the protruding lifting cable through the upper part of the hydraulic jack.
    [0051]
    [0052] In the same way, the module can also comprise at least one cable collection element that can also be arranged in an elevated position, in such a way as to facilitate the movement of workers. In this sense, this situation of the collection element greatly facilitates the operations to be carried out, allowing free movement of operators and meaning another great advantage of the invention by reducing the dimensions of the work platform and / or avoiding its installation. Said collection element may be in the form of a drum, "recoiler" or any similar or equivalent element known in the art. The collection element can be passive or active, incorporating an engine or equivalent to assist in the deployment and / or folding of the lifting cable.
    [0053]
    [0054] Additionally, the mobile module may also comprise a guiding element in contact with the ascending section, preferably sliding, rolled and / or by means of track-type elements.
    [0055]
    [0056] On the other hand, the lifting procedure for telescopic towers described above may include lifting at least two different sections of the tower, repeating its main steps to hoist different sections of the tower. In this case, said procedure can be characterized because, initially, the innermost section of the tower is hoisted and it is still hoisted from the innermost to the outermost.
    [0057]
    [0058] In said lifting procedure of telescopic towers, the heads of different sections of tower to be hoisted can be located substantially at the same level. In this way, the mobile module of the invention can be moved radially for positioning in the heads of the different tower sections, through at least one means of horizontal displacement, for example one or more rails.
    [0059]
    [0060] Likewise, said method can be characterized in that the described grouping means can be recoverable and comprise:
    [0061] - a screwed wedge plate
    [0062] - a first distribution plate screwed to said wedge plate
    [0063] - a second distribution plate with a hole through which said wedge plate can pass.
    [0064]
    [0065] Said wedge plate may comprise a protective element that allows it to pass through the conduits of the different sections intended to accommodate the lifting cables. Also, said protective element of the wedge plate can be pointed to avoid jams.

    [0092] DETAILED DESCRIPTION OF THE INVENTION
    [0093]
    [0094] Figures 1-7 illustrate different views of the mobile module (1) of the invention for lifting telescopic towers (100), preferably wind towers (101). In a preferred embodiment, the mobile module (1) comprises a hydraulic jack (2), a hoisting cable (3) pre-installed through the hydraulic jack (2) and which remains connected to said jack throughout the entire process of lifting of the telescopic tower (100), and grouping means (4) arranged substantially at the free end of the lifting cable (3).
    [0095]
    [0096] Preferably, the lifting cable (3) is formed by a plurality of strands (3 ') (see schematic distribution thereof in Figure 6). The cable (3) crosses the hydraulic jack (2), so that the upper end thereof preferably protrudes from the upper part of the hydraulic jack (2), and its lower end protrudes from the lower part of the hydraulic jack (2) ( see Figures 2-3), said lifting cable (3) remaining connected to the hydraulic jack (2) throughout the entire lifting procedure of the telescopic tower (100) (see, for example, Figure 5).
    [0097] More preferably, the strands (3 ') are integrated in the lifting cable (3) independently, that is, the strands (3') are not interwoven with each other, nor mechanically connected, but are grouped together in a substantially parallel beam.
    [0098]
    [0099] The mobile module (1) of the invention also has grouping means (4) designed to prevent crossings of the strands (3 '), as well as to facilitate the routing of the lifting cable (3) through the head of a support section (211) and the base of an ascending section (210) (see said sections in Figure 5) of the telescopic tower (100). The lifting cable (3) can, additionally and as shown in Figure 7, have pointed geometry to facilitate its guidance through said sections (210, 211).
    [0100]
    [0101] Additionally, the grouping means (4) are essentially located at the lower end of the lifting cable (3), which keep all the strands (3 ′) that integrate said lifting cable (3) together. In addition to grouping, the grouping means (4) contribute to keep the strands (3 ') positioned, to maintain the distribution of the same that is used both in the hydraulic jack (2) and in the lower end of the cable, and can also act as anchoring means for maintaining said position.
    [0102]
    [0103] In complementary embodiments of the invention, the grouping means (4) can be removable and can be removed to add anchoring means, and added again at the lower end of the cable at a later time in the tower lifting procedure (100)
    [0104]
    [0105] As described, the mobile lifting module (1) of the invention allows a double direction in the movement of the lifting cable (3) through the hydraulic jack (2), said lifting cable (3) being able to both extend in the direction essentially descending, like picking up in an essentially ascending sense.
    [0106]
    [0107] In a preferred embodiment of the invention, the average diameter "D" of the lifting cable (3) is less than 4 d (N) 1/2, "d" being the average diameter of the strands (3 ') that make up the lifting cable (3) and "N" being the total number of strands (3 '). In this way, it is achieved that the lifting cable (3) has adequate dimensions to cross the flanges of the sections (210, 211) of the telescopic tower (100).
    [0108]
    [0109] The mobile module (1) of the invention preferably comprises a support frame (2 ') to which the lower part of the hydraulic jack (2) is fixed, and which comprises a gap for the passage of the lifting cable (3), whose dimension allows the grouping means (4) to be accommodated. Thus, the mobile lifting module (1) can adopt a transfer condition in which the lifting cable (3) is fully retracted or picked up, and in which the lower end of the lifting cable (3) and the means of grouping (4) are housed in a recess of the frame (2 '). Thanks to this configuration, the mobile module (1) can be moved between hoists or between towers, or even between parks, resting on its frame (2 '). For this, in the transfer condition it is avoided that the cable (3) protrudes below the frame (2 '). Also, in different embodiments of the invention, the mobile module (1) may comprise one or more lifting points (not shown in the figures) that allow it to be suspended completely. Said lifting points are preferably located substantially in the vertical center of gravity of the mobile module in its transfer condition.
    [0110]
    [0111] In another preferred embodiment of the invention, the frame (2 ') can adopt a horizontal dimension such that the mobile module (1) simply supported on said frame (2') is sufficiently stable against horizontal loads, which facilitates the collection and transfer of module (1), for example, between park towers.
    [0112]
    [0113] In another preferred embodiment of the invention, the frame (2 ’) comprises horizontal displacement means (8) to facilitate the horizontal movement of the mobile module (1) for different lifts. Said displacement means (8) can be of any of the types known in the art for the movement of equipment, such as rails and / or rolling means, or elements to facilitate the sliding of the module (1). They can also incorporate or employ pushing or pulling means to apply the force that moves the module (1) from one position to another (for example, from the head of a support section (211) to the next).
    [0114]
    [0115] In a preferred embodiment of the invention, the mobile module (1) additionally comprises one or more work platforms and / or equipment storage, preferably connected to the frame (2 ’). The equipment that can be housed in the aforementioned platforms are typically "power pack" systems (hydraulic pumps), or "manifolds" that allow the cats (2) to be hydraulically fed and / or control their operation. They can also incorporate telecommunication means to facilitate remote control of the mobile module (1).
    [0116]
    [0117] Figure 2 shows a preferred embodiment of the mobile module (1) which further comprises a cable guide structure (5), which allows the cable guide to be guided. hoisted (3) hydraulic jack projection (2). Said cable guide structure (5) acts throughout the lifting process of the sections of the telescopic tower (100), directing the cable towards a cable collection element (6) also included in the mobile module (1). In this case, said cable collection element (6) is arranged in an elevated position, so that the movement of workers through the corresponding work platform (300) is facilitated during the lifting process of the telescopic tower ( 100). In this way, the need to install a larger platform, consequently more expensive, is eliminated.
    [0118]
    [0119] Figure 3 represents an embodiment of the mobile module described in the present invention which additionally incorporates a guiding element (7) in contact with the ascending section (210). Said contact may preferably be sliding, rolled and / or by means of track type elements. Thus, said guiding element can exert a force perpendicular to the structure to restrict possible inclinations of the sections of the telescopic tower (100) during the lifting process.
    [0120]
    [0121] Figure 4a shows a front view of another preferred embodiment of the invention. In this case, the mobile module (1) comprises two hydraulic jacks (2) and the corresponding lifting cables (3), cable guide structures (5) for guiding said cables and the cable collection elements (6 ). In addition, this embodiment also comprises a guiding element (7) located between the two hydraulic jacks (2). This embodiment allows greater lifting force in case the sections to be lifted require more powerful means, while optimizing the entire lifting process of the telescopic tower.
    [0122]
    [0123] Figure 4b illustrates a plan view of a possible lifting configuration of a telescopic tower with several integrated modules (1) arranged homogeneously in the perimeter of the tower sections to be hoisted. In this figure, the possible arrangement of the horizontal displacement means (8) (for example, rails) included in the procedure and allowing the movement of the mobile module (1) for its positioning in each lifting stage can be observed.
    [0124]
    [0125] In this embodiment, the arrangement of a reduced work platform (300) can be observed thanks to the fact that the cable collection elements (6) are arranged in an elevated position so that the movement of workers is facilitated.
    [0126] It is also possible to observe the additional arrangement of three lifting modules (1) arranged in the outermost section of the tower (100) that act only in the last lifting phase due to the need to lift the entire structure, with a lot of weight greater than in the previous phases.
    [0127]
    [0128] Figure 5 represents a possible embodiment of the lifting procedure described in the present invention.
    [0129]
    [0130] Figure 5a shows a first lifting stage where the mobile module (1) is located first in the head of the support section (211) which in this case is the immediately adjacent section (202) and the lifting cable is fixed ( 3) at the base of the ascending section (210) which in this case is the innermost section of the tower (201) by means of grouping (4) located at the base of said section to subsequently proceed with its lifting by collecting said cable.
    [0131]
    [0132] Once hoisted, as shown in Figure 5b, the base of the hoisted section (201) is fixed to the head of the support section (211), releasing the grouping means (4) and releasing the mobile module (1) of the head of the support section (211). Next, Figure 5c illustrates the movement of the mobile module (1) in one piece to the head of the next support section (211), which in this case is the immediately adjacent section (203). In this case, the displacement is carried out by lifting the module by means of cranes, although it can also be carried out by sliding the module through the horizontal displacement means (8).
    [0133]
    [0134] Figure 5d shows the next lifting stage where the lifting cable (3) slides and is fixed at the base of the new ascending section (210).
    [0135]
    [0136] Figure 5e represents a subsequent lifting stage where the previously fixed sections (201, 202) are hoisted.
    [0137]
    [0138] Finally, Figure 5f shows a next stage and analogous to the stage represented in Figure 5b, where the sections (201, 202) hoisted to the support section (211) are fixed.
    [0139]
    [0140] As previously described, an advantage of the process of the invention is that it does not require any connection and / or disconnection step between the lifting cable (3) and the hydraulic jack (2), nor any operation of laying loose cables. Of that mode, the mobile module itself (1) is capable of deploying the collected cable (3) to place it in the lifting position.
    [0141]
    [0142] Figure 6 illustrates an embodiment of the grouping means (4) described in the present invention, comprising a screw wedge plate (9), a first distribution plate screwed to said wedge plate (10) and a second plate of distribution (11) with a hole through which said wedge plate can pass.
    [0143]
    [0144] With this configuration it is possible to carry out the lifting procedure avoiding the placement of the wedge plate (9) in each lifting phase, keeping the lifting cable (3) in line and connected to the hydraulic jack (2) throughout the entire process.
    [0145]
    [0146] Finally, Figure 7 shows a protective element (12) installed in the wedge plate (9) so that it allows it to pass through the conduits of the different sections intended to accommodate the lifting cables (3). In addition, said protective element (12) can be pointed, to avoid blockages in the ducts.
