    Distribution device for dense substances, especially concrete
    [2] Such dispensing devices are already known (for example EP 432 854 and WO 00/24988). Such dispensing devices are provided with a telescopic boom section that is bendable in a slewing track ring for the dispenser and is provided by a hydraulic cylinder unit. It may be pivoted from a parallel transport or stop position to a substantially vertical working position. The distribution boom is mounted on a suitable vehicle, possibly on a lorry or crane truck, by means of this large track ring. Such distribution booms are provided for supporting conduits, especially concrete transport conduits, and are mostly used for concrete distribution for manufacturing ceiling slabs in buildings and the like. Because of this, the concrete conveying conduit is supported by the telescope section of the distribution boom, and as the boom extends, the concrete conveying conduit must also be adjusted according to the boom. To this end, scissors (vertical) conveying conduits are known which consist of swivelling elements connected to each other by articulated joints. When the telescope section of the boom is unfolded, these conduit elements rotate in the same manner as the scissors, so that the joint-conveying elements with joint seams move past each other, after which the conveying conduits follow the telescope movement. It becomes possible.
    [3] In the case of a distribution device according to EP 432 854 B1, a reinforcement beam is provided to both the relative fixed compartment and the flow compartment of the telescope, and away from the telescope and the concrete-carrying conduit section guiding in the telescope direction. Each part is attached to the reinforcement beam. This induces a very large, heavy and space-consuming structure of the telescope compartment of the boom and a significant force on the extendable part of the telescope that supports the following compartment of the conveying conduit, especially during operation. Large forces are applied, such as when pressure is generated or when a large pumping stroke is generated when the pumping head moves. For this reason, moderately heavy telescope structures are required. On the other hand, in the case of a distribution boom according to WO 00/24988, a concrete-carrying conduit consisting of joints is connected to the telescope section of the boom by a bearing block, which also has a generous design on the side of the boom. Required.
    [4] It is an object of the present invention to provide a dispensing device having a telescope boom section with a compact structure and good load distribution, which has a considerable stability thereto.
    [5] According to the invention, this problem is solved by the features contained in the features of claim 1, while further improvements and embodiments of the invention are specified by the features of the dependent claims.
    [6] According to the invention, a reinforcement beam is provided in the telescope section of the boom that supports the concrete conveying conduit and connects the two telescope parts to each other, so that one end of the reinforcement beam extends from the telescope. And the other end of the reinforcing beam to engage with the relatively fixed part. That is, the reinforcing beam is coupled to the two telescope parts, which are present in the carrying position and also in various intermediate positions that define the working position, in which the extendable part of the telescope is reached with an appropriate extension. . In the telescope's extended position, this reinforcing beam makes it possible to introduce forces very well to both parts of the telescope, which also benefits the desired stable structure of the dispensing device. At the same time, this leads to a reduction and simplification of existing construction efforts. For good force and moment distribution and cost savings, it would be particularly advantageous if the concrete-carrying conduits in the telescope partial area could be aligned on both sides of the boom. That is, if the portion of the concrete-carrying conduit that leads in the telescope direction is aligned on one side of the boom, while the portion of the concrete-carrying conduit that is directed away from the scissor assembly and the telescope toward the tip of the boom It would be particularly useful to align to this other aspect. This ensures a very good compensation of force. The fact that the reinforcing beam is guided by an extension guide rail connected to the relatively fixed part of the telescope, and that the reinforcing beam is fixed to the extendable part of the telescope is that the telescope carries the concrete-conduit Ensure free guidance of supporting reinforcing beams. Because of this, it is advantageous if the reinforcing beam is designed to resist bending or torsion, especially if it is designed as a hollow section. The fact that both ends of the reinforcing beam are connected to the parts of the telescope by rotating seams ensures very good load reception and force distribution.
    [7] In particular, it would be beneficial if the concrete-carrying conduits were aligned on both sides of the boom in the telescope partial region if the rotating elements of the scissor assembly were designed to be S or C shaped.
    [8] Joint points of the scissor assembly, i.e. the parts connected with the respective sections of the concrete-carrying conduit leading both the ends of the scissor assembly toward and away from the ends, respectively, and the rotating elements of the assembly are connected to each other The seams located in the part are advantageously designed with a swivelling pipe joint that can prevent bending. This design offers advantages in terms of pumping thrust, which occurs whenever a change in the pumping head occurs during operation. This also contributes to the stable design of the dispensing device.
    [9] In a further refinement of the invention, the hydraulic cylinder for the folding section of the boom connected to the telescope section by articulation is bent by known articulation in the leading end region of the extendable portion of the telescope. The other end of the telescope is firmly connected to the folding section of the boom. Such a structure has the advantage that the maximum use consists of an extension path, in particular, unlike the case of conventional building techniques, that the maximum use is not reduced by the overall length of the hydraulic cylinder. This is because the hydraulic cylinder is articulated in the front compartment of the boom. This further improvement of the present invention allows the outer part of the telescope to retract into the articulation linkage when the telescope is folded into its final position. Here, we are interested in this further improvement, but we are also interested in the principle of higher invention of its own right, which is independent of the reinforcement beam installation between the two telescope boom components and can be useful in other conditions. .
    [10] Finally, if there is a bundle of other conduits and hoses, such as hydraulic conduits and hoses, electrical cables, etc. that are needed to ensure energy supply, then concrete-conveying conduits in the telescope section of the boom. It would be even more beneficial if the bundles were guided along the path of the scissors assembly and connected by appropriate means. In such a connection, it would be particularly useful if the feed bundle is protected and housed inside the hollow compartment of the reinforcing beam.
    [11] A further advantage can be obtained by combining the telescope boom compartment with further boom segments articulated and foldable thereto. This combination gives the distribution boom an improved slip-in characteristic. That is, the end of the boom allows for easier passage through windows or other wall openings. As a result, the distribution boom will be particularly advantageous for use on construction sites where the possible working altitude is limited, and can also be used inside the hall.
    [12] Now, preferred embodiments of the present invention will be described with reference to the drawings. All drawings are purely outlined and are as follows.

    [27] Along with the overpass ring 2, the dispensing boom 1 shown in FIGS. 1-3 is generally mounted on a power source, possibly a powered lorry or a mobile crane truck, but if necessary bristle in a fixed position. It can also be built. The illustrated dispensing boom is provided with a telescope section 4, which is articulated to the large track ring 2 at position 4, the first fixed or external telescope component 5 and It consists of a second or internal telescope component 6 which can flow inside the first telescope component. The telescope boom section 4 can be rotated by means of a hydraulic cylinder 7 at an angle of up to 90 ° from the horizontal transport position shown in FIG. 2 to the working position shown in FIG. 1. For this purpose, the hydraulic cylinder 7 is articulated to a bracket 8 having the other end protruding from the large track ring 2 and articulated to the bracket 9 arranged on the outer telescope component 5. . An angle bracket 10 is provided at the upper end of the extendable telescope component 6 pointing in the direction of the dispensing boom, where there is an additional collapsible section 11 of the articulated boom. do. This compartment supports another boom compartment 12, which in turn supports a third collapsible boom compartment 13, which constitutes the end of the boom, with all seams being properly articulated. In particular to these moving boom sections 5 to 13, concrete-carrying conduits are attached and are not shown in FIGS. 1 to 3 for simplicity of presentation. This concrete-carrying conduit is finished with a resilient outlet located at the boom end 14, and when the dispensing boom is properly extended and rotated, the concrete-carrying conduit is moved to any desired working position to distribute the conveyed concrete. Can be.
    [28] In one embodiment, FIG. 1 is provided with hydraulic cylinders 16, 17 for collapsible boom sections 11-13, with the boom sections 11 and 12 being folded by a so-called Z-fold. Higo, on the other hand, the outermost boom section 13 can be folded rearwards by a so-called rolling fold. Such a fold is shown in FIG. 2. More specifically, when the dispensing boom is in the transport position shown in FIG. 2, the boom section 11 is rotated in the direction of the arrow shown in FIG. 1 by the hydraulic cylinder 15, while the boom sections 12 and 13 rotate in the direction indicated by the arrow. 1 to 3 show that, if a dense structure is obtained, all flow parts must be carefully connected to each other, in particular the alignment of the concrete-carrying conduits described in more detail in later figures. Draw out the fact that it fits the purpose.
    [29] For this reason, both schematics of FIGS. 4 and 5 are shown in which the telescope boom section 4 is mounted on the large raceway ring 2, where the dashed line and the partial solid line 17 represent concrete-carrying conduits. Concrete-carrying conduits generally consist of pipes connected to one another in a pipeline manner, but may also be partially or wholly hose hoses. The concrete-carrying conduit 17 is attached by flange connection in the region of the large raceway ring 2 and can be supplied by a concrete pump, in most cases by a high density material, in particular a twin-cylinder pump for concrete, The pump is generally mounted on a powered lorry or crane truck. In view of compensating for the telescope movement of the telescope boom compartment 4 due to the extension of the second telescope component 6, a scissor conduit assembly indicated by reference numeral 18 is provided in the telescope boom compartment area, In the same case, the scissors conduit assembly consists of a rotating element 19 and a second rotating element 20. The two rotating elements 19, 20 are connected to each other by articulation seams 21. In addition, another joint seam 22 connects the rotating element 18 to the compartment 23 of the concrete-carrying conduit 17 which leads away from the scissors assembly. The compartment 23 of the concrete-carrying conduit leading away from such scissors is connected to the reinforcing beam 24 and, more particularly, to the upper surface of such a beam, as can be seen in FIG. 5. It is connected. The points to which the conduits are attached are indicated by reference numerals 25 and 26.
    [30] In such a case, the reinforcement beam 24 is arranged on one side of the relatively fixed telescope component 5, and more particularly, is installed in such a way that the reinforcement beam can move along the telescope. For this reason, the extension guide rail 28 indicated by broken lines in FIGS. 4 and 5 is aligned with the side of the telescope component 5. As can be seen in FIG. 7, the longitudinal guide rail 28 is provided with a dovetail groove, where the reinforcing beam is guided by a slider 29. Such a position of the moving bearing may be replaced by a bearing having a form of a wheel or the like. The type 29 is advantageously connected to the reinforcing beam by a fulcrum pin 30.
    [31] At the other end, the reinforcing beam 24 is connected to the extendable inner telescope component 6, more particularly by the rotating pin 31. The fact that the reinforcement beam 24 is attached so that it can be bent to the boom through the lever pin 30 and the rotary pin 31 respectively, when the internal telescope component 6 is extended, This will be dragged along, which means that the concrete-carrying conduit section 23 supported on the reinforcing beam will also be dragged. This will involve the movement of the two rotating components 19 and 20, and to the same extent as the rotating element 19, a given joint seam 22 will rotate clockwise as the telescope component 6 is extended. On the other hand, since this rotating element 20 is connected by joint seams to the bottom of the relatively fixed boom section 5, the rotating element 20 articulated with the rotating element 19 is counterclockwise. Will be rotated. The concrete-carrying conduit section leading from the large track ring 2 to the joint seam 31 is indicated by reference numeral 32. Such conditions are more clearly depicted by FIG. 7. In addition, FIG. 7 shows that the rotating element 20 is designed in an S shape, while the rotating element 19 is designed in a C shape. This is advantageous for the structurally compact placement of supported concrete-carrying conduits. The two C-shaped arms of the rotating element 19 terminate at the joint seams 21 and 22, while the ends of the S-shaped rotating element 20 terminate at the joint seams 21 and 31. When the telescope component 6 is extended, the scissor assembly 18 rotates in such a way that the joint seams cross over each other so that the concrete-carrying conduits present in the telescope boom compartment area extend the telescope's extension. You can follow. This is more clearly shown in FIG. 14, which shows the various working positions reached during the extension of the internal telescope component 6. It can be seen that the concrete-carrying conduits in the area of the scissor assembly are made to follow the boom due to the fact that the joint seams 21, 22 and 23 move past each other during extension. However, as an alternative to the scissor assembly, it is also possible to use a hose tube with an appropriate calibration loop, which allows telescope movement to follow as the inner component extends outward. However, such conditions are not shown in the drawings.
    [32] In terms of structural compactness and assurance of adequate compensation of forces and moments, as shown in FIG. 5, the concrete-carrying conduit section 32 which leads in the direction of the shear assembly is positioned at the position where the reinforcing beam 24 is attached. It is installed on the side of the first telescope component 5 on the opposite side. In the area of the telescope boom compartment, concrete conveying conduits are provided on both sides of the boom compartment 4. As is shown schematically in FIG. 7 for the case of the seam 31, the joint seams 21, 22 and 31 of the scissor assembly are designed with a rotary tube connection that can resist bending. To this end, the end of the conduit adjacent to the seam is rotatably received in the bushing. However, because of this, the ends of the conduit are tightened by means of a sleeve attached by welding or other means. 13 in connection with a seam 31 located on the underside of the telescope component 5 shows a suitable embodiment of such a rotatable conduit bearing. In this case, the end of the introduction concrete-carrying conduit 32 is designed with a rim 36 and is connected to a corresponding bearing conduit 37 terminated with rims on both sides, the connection being a schematic muff ( Obtained with the help of 38). The bearing conduit 37 is received in the bushing 40 attached to the telescope component 5 together with the bearing element 39, preferably by welding. The end of the S-shaped scissors element 20 can be observed on the right side. This end is welded to the corresponding rim of the bearing conduit 37.
    [33] Finally, a piston-face in which the hydraulic cylinder 15 is attached by joint seams to the leading end of the telescope component 6, ie at the end towards the end of the dispensing boom, or more precisely, to each bracket 10. It can be seen in Figures 1 and 4 that it has a terminal. Although the intermediate seams are only schematically shown in FIG. 5, they are shown in more detail in FIG. 1. The cylinder face of the hydraulic cylinder 15 is articulated to the next boom section 11, more precisely to the traverse bracket 33 of the middle region of the boom, as can be seen in FIG. 1. . Different from conventional arrangements (hydraulic cylinder has one end connected to joint linkage 34 and the other end attached to boom section leading seam, in special case connected to internal telescope 6) Because of the unique arrangement of the hydraulic cylinder 15, the possible throw of the telescope section of the boom is extended, while the maximum length of the hydraulic cylinder is somewhat reduced in conventional designs. Therefore, when the external telescope component is retracted to the distal position, since the external telescope component 5 can be moved directly to the articulation linkage 34, the above described arrangement makes it possible to obtain the corresponding telescope extension. do. 8-12 show the actual design of the concrete-carrying conduit 17 in detail. 9 and 10, which are perspective views of FIG. 8, show the dispensing booms in the boom section in the folded back position, while FIGS. 11 and 12, which show the telescope section of the boom without other boom sections, extend fully. Showing the boom compartment in the correct position. The rotating elements 19 and 20 of the S and C shapes, respectively, can be seen very clearly in FIG. 12. In this connection, it should be noted that certain details, in particular those including the reinforcing beam 24, have been omitted to make it easier to understand FIGS. 8 to 12. The reinforcement beam 24 is attached to one side of the relatively fixed part of the boom, ie the telescope component 5, and supports the concrete-carrying conduit, thereby ensuring free guidance. 1, in particular due to the fact that the telescope boom compartment 4 is connected to the large track ring 2 and the other boom compartments are connected to the telescope boom compartment by articulation seams. Particularly suitable for construction sites where this open working height is limited, and because this structural arrangement has very good sliding properties, the tip of the boom is very easily introduced into windows or other wall openings to access the interior space. To be possible. Because of the stepless adjustment capability of a given telescope boom compartment, it can be manufactured to support building edges with millimeter accuracy.
    [34] As can be seen in FIGS. 6 and 7, the two telescope components 5 and 6 are designed as box sections having a substantially rectangular cross section. Likewise, the reinforcing beam 24 is also designed as a box compartment, ie a completely closed hollow compartment, the shape of the cross section being also substantially square.
    [35] Other supply lines, including hydraulic hoses, electrical cables, and pipes, are bundled together, thereby forming a supply bundle that, together with the elements of the concrete-carrying conduit, can be easily manufactured to follow the path corresponding to the scissor assembly. .
    [1] The present invention relates to high density materials, in particular concrete distribution devices.
