    Lifting device for the wheelhouse of a ship
    The invention relates to a lifting device for the wheelhouse of a ship according to the preamble of claim 1.
    For wheelhouses on ships, lifting devices have long been known. In DE 411 427 (1925) a steering house for a ship with height adjustment is proposed, wherein a device comprising a worm gear with pinion engages the bottom plate of the steering house and can move it. In DE 736 016 a steering housing is moved by respective height-adjusting members present on two opposite support posts, wherein a rack with a corresponding pinion shaft is used as a drive.
    In the lifting device for a steering gear according to DE 911 428, a lifting cylinder driven with compressed air is arranged as a central lifting device, which is connected by cable or cable. chain traction is combined into a lifting device. A similar device according to GB 859,603 uses a lifting cylinder in combination with scissor arms engaging under the steering housing and also in DE 1 079 493 a lifting cylinder is used for displacing the steering housing by means of a support unit forming a vertical sliding connection. According to DE 18 81 426 the steering housing is formed as a box-shaped construction unit, which can be moved up and down by a lifting cylinder between respective guide posts. A lifting cylinder combination is also provided in DE 19 21 426 for displacing the steering housing, which has a cable protection located on the edge side. In DE 71 31 224 lifting elements are also arranged under the steering housing in the form of stamp pistons and DE 71 35 595 shows two parallel lifting cylinders under a command bridge.
    In a construction according to DE 30 10 984, a liftable control housing is rotated over an arc-shaped path of movement by a hydraulic cylinder engaging swivel arms and pivot-like pivot supports are provided in DD 208 120. A similar construction is shown in WO 01/85534 A2 and also in FR 2498555, JP 62139785 A, DE 43 24 397 A1 as well as in US 6,988,461 B1 hydraulic lifting units for wheelhouses on ships respectively. general steering construction groups.
    In US 3,942,458 (1967) a construction is proposed with more telescopic columns rectangular in cross-section as a lifting construction group, wherein by means of only one central lifting cylinder the steering housing present at the top of the construction part can be vertically raised. These columns, which are rectangular in cross-section and which form a cross-section of telescopic shafts, always have roller guides on the side plates connected by means of more welds, so that the system can be displaced relative to a receiving shaft in the ship's hull.
    The invention relates to the problem of providing a lifting device for the wheelhouse of a ship, the lifting group of which can be manufactured with low technical costs and with comparatively little use of materials, the telescopic individual parts optimizing their long-term stability and torsional rigidity. conductivity and forms an accurately controllable unit with the improved drive of the system.
    The invention solves this problem by means of a lifting device for a ship's wheelhouse with the features of claim 1. Other advantageous embodiments are disclosed in claims 2 to 19.
    The lifting device for a ship's steering house is improved in the area of the lifting construction group thereof, in that the at least one tube body thereof arranged as a displaceable basic lifting part is formed in the embodiment according to the invention with a wall consisting of one whole, so that the tube body in cross section at least partially has an arc of a circle. Starting from this circular arc-shaped circumference, the tubular body consisting of a whole can be combined in the area of its closed wall with a support which, in the manner of a telescopic rail guide, determines the substantially vertically oriented installation position of the total lifting system in the area of the ship's hull and thereby guarantees the buckling and torsional strength of the system at low costs.
    This circular arc-shaped circumference of the tubular body, which is integral with one another, leads to an optimum operating unit in view of the use of materials for the joint components and the stability to be achieved in this regard. This is distinguished by the fact that a corresponding thin-walled design of tubular bodies is possible, which - after a comparatively simple manufacture with a rolling or tubular process - only require a single longitudinal welding seam and the tubular bodies with corresponding technological advantages are faster for installation in the system. can be made available.
    Starting from the construction with circular arc-shaped circumference of the tubular body, it can be produced particularly efficiently if this wall is designed as a circular ring in cross-section. This "open cylinder" in an intermediate step of the deforming manufacture is formed from a plate-shaped semi-finished blank on a standard rolling machine, and then the longitudinal gap thereby obtained can be closed by a single weld seam. It is likewise conceivable that in a changed course of the rolling or milling machine. bending process the tubular body is formed with a wall which forms a circumference enclosing a circle segment in cross section.
    The construction of the lifting device has more of the telescopic interlocking, in particular closed, cylindrical tubular bodies with corresponding diameters. These can be formed with a size that always achieves a partial stroke length of more than 2 m and thereby form the telescoping sections supporting each other. In the connection region of these cylindrical tubular bodies, more telescopic rail guides with sliding and / or roller bearings are preferably arranged. Starting from the concept of the cylindrical tubular bodies, it is conceivable that even a single of the vertical guides arranged in the interspace of the tubular bodies may be sufficient for the operation of the system.
    For lifting control of the telescopic tube system, a hydraulic cylinder construction group with one or more lifting cylinder (s) is arranged in the interior of the telescopic tube body, wherein in particular also an opposite displacement of the moving parts on narrow space is possible. The lifting cylinders are herein preferably arranged in the manner of a master-slave-cylinder system, with which a particularly efficient and precisely controllable embodiment of the drive is obtained. A telescopic cylinder with cascade switching can also be advantageously arranged.
    Other details and advantageous features of the embodiment are to be found in the following description and the drawing, in which the lifting device for a wheelhouse of a ship is made more visible on the basis of an exemplary embodiment. Show in the drawing:

    Fig. 1 shows a steering house of a ship, indicated in total by 1, which is connected via a lifting device 2 to a multipart hull 3 of a ship (not shown). Such a lifting device 2 is in principle known from US 3,942,458, wherein a lifting construction group corresponding to the device 2 is arranged vertically in a receiving shaft 4 of the hull. By means of a drive generally indicated by 5 (Fig. 5), the lifting construction group engaging in the area of the receiving shaft 4 in the ship's hull 3 can move from the lowered position shown in Fig. 2 (arrow L) into the position shown in Fig. 4. the elevated position (arrow A) shown in the above-mentioned position (arrow A) are moved and returned therefrom, in such a way that the wheelhouse 1 of the ship can assume suitable positions of use, in particular for looking over the cargo.
    The concept according to the invention with the lifting construction group arranged as the basic part of the lifting device 2 assumes that at least one tubular body K displaceable by means of the drive 5 - as (the only) lifting element - in the region of the wall 6 thereof ( Fig. 3) has at least partially a substantially circular arc-shaped cross-sectional circumference and this tubular body K is held by at least one support 7 in the manner of a telescopic rail guide both rotatably in the mounting position (Fig. 1, Fig. 6) and vertically outwards and can be led inwards (fig. 2, fig. 3).
    It is clear that this shaping of the tubular body K - with its at least partially circular arc-shaped cross-sectional circumference (FIG. 10, FIG. 11) - permits a surprising number of structural and technological improvements for the lifting device 2. Starting from the concept of the tubular body K is formed as a circular ring-shaped cylinder (Fig. 2 to Fig. 6) around the arc-shaped circumference, because of the up to now necessary high manufacturing costs - which are caused by the welds on the corner edges of wall plates (US 3,942,458) - to lower. It is likewise conceivable that the tubular body K resp. its one-part wall 6 is formed as a hollow sectional part forming a circular section S (Fig. 10, hatched striped image) in cross-section.
    The tubular body K herein forms a lifting element, the manufacture of which already has substantial technological advantages, in that the tubular body K consisting of a whole is formed from a plate part suitably cut in length and width, and after this chipless deformation is only still in the region of a a single profile seal must be made for a single (vertical) weld seam. The intermediate product to be further processed in the form of the "cylinder tube" is thus made available and can be mounted with the guide parts forming the mutual support 7. It is likewise provided that the tubular bodies K are composed in longitudinal direction of more sections. The tube sections (M, M ", M" - Fig. 2) formed for this purpose from the corresponding parts of the plate parts are connected in the region of the abutting end faces by a welded seam Q, Q ". The connecting position of these pipe sections is thereby indicated in such a way that the relevant longitudinal weld seams (vertical dashed line U, U 'in Fig. 2) are offset radially with respect to each other and thus the strength of the assembled pipe body K also with more welded sections. M, M ', M ”is largely not affected.
    This closed cylinder circumference in the region of the wall 6 allows a weight reduction in view of the cost reduction, because the cylindrical tubular body K has a high rigidity at low manufacturing costs and is thereby sufficiently stable for buckling. With the corresponding arrows W resp. W 'and W' are the relevant loads of the lifting device 2 (in Fig. 1) relevant for use in practice - for example, by wind pressure - schematically represented, whereby the lifting device 2 also shows the weight load of the lifting device made visible by an arrow G wheelhouse 2 must be kink-proof.
    In the simplest embodiment, according to the invention, a lifting device 2 can be realized, wherein a tubular body K can be attached directly to the receiving shaft 4 of the ship's hull 3 by the at least one telescopic rail guide acting as non-rotatable and kink-safe support and not vertically displaced (not displayed).
    In the illustrated embodiment of the lifting device 2 (Fig. 1), more tubular bodies K, K 'and K' which engage under the control housing 1 are arranged with a vertical upright axis H, these being arranged in the manner of telescopic tubes (with corresponding diameters D, D ', D') with slidable cross-sectional contours (Fig. 3, Fig. 4) form the lifting structure group. A construction of the tubular bodies K, K 'is conceivable, wherein these can be lowered substantially completely into the receiving shaft 4 of the ship's hull 3 (not shown). It is clear from Fig. 1 that the one tubular body K 'is designed as a basic tubular body of the lifting device 2 such that the two lifting elements in the form of the telescopically displaceable tubular bodies K, K' can be lowered therein (Fig. 2 , fig. 5). It is also conceivable here that only the tubular body K "if the part present in the ship's hull 3 is provided with a rectangular cross-sectional circumference (not shown) and the cylinder tubes according to K resp. K ’can be moved in here.
    In a cross-section according to Fig. 6, it is clear that the tube bodies K, K 'always have outside diameters D, D' which are tuned to the telescopic displacement and thereby the respective telescopic rail guides 7, 7 ', 7 ", 7" between these circular ring circumferences. ' are provided. In the vertical arrangement of this system (fig. 4 to fig. 7) it becomes clear that both between the two lifting elements in the form of telescopic tube bodies K, K 'as well as between the base tube bodies K' and the middle tube body K always at least one of the telescopic rail guides 7 is provided, wherein as identical construction parts they are not provided with reference numerals in all illustrations. These supports have an abutment area always formed in the manner of a profile beam 8, which cooperates with the respective support bearings generally indicated by 9. These support bearings 9 can be designed in the form of roller bearings (Fig. 12, Fig. 13) or slide bearings 11 (Fig. 16, Fig. 17).
    Starting from this structural concept of the lifting device 2 built up in the manner of a "cylinder tube sleeve" and offering surprising economic advantages, it is conceivable to design the tube cross sections shown in Figs. 10 and Fig. 11 by suitable profiles 12, 13 such that In the area of these profiles 12, 13, structural components in the form of the support bearings 9 can be directly attached and thus a non-rotatable and kink-stable guide of the tubular bodies K, K 'is possible. It has been found that in the result of load tests (arrows W, W 'and W'; arrow G in Fig. 1) even more material savings can be obtained because the relevant thickness B, B 'of the wall 6, 6' ( Fig. 10, Fig. 11) is optimized in accordance with the load in the maximum outwardly displaced position shown, and in particular reductions in the sheet thickness (B, B ') of the tubular bodies K, K', K 'on advantageously notch-free manufactured cylinder circumferences are possible.
    Considering the figures 5 to 9 together makes an embodiment of the drive 5 for the cylindrical tubular bodies K, K 'clear with an adjustment unit 15 shown in detail in Fig. 8. Instead of this adjustment unit 15 are other drive concepts, not further shown. conceivable, whereby as a technical requirement uniform lifting and lowering movements as well as a braked lowering of the steering housing 1 in the lower input position are required. Moreover, it must be possible to achieve the relevant intermediate positions of the wheelhouse, and also to ensure controlled lowering in an emergency situation, for example for avoiding collision with bridges. To this end, plunger-cylinder units with cable feed rollers can be integrated into the system. The costs and material costs involved are, at the same time smaller kink safety, so high that these designs are not very suitable. A mechanical version with more cable winches in the interior of the system or the arrangement of drive motors and racks also requires high technical costs, so that all these systems are disadvantageous in the technical realization.
    The embodiment of the adjustment unit 15 shown in Fig. 8 has been found to be effective, with structurally simple hydraulic cylinders in the form of plunger-cylinder units being arranged as identical structural parts. These three hydraulic cylinders 16, 17, 18 are thereby designed for accurate synchronization with the outward and inward direction of movement. The two parallel outer cylinders 17, 18 are advantageously connected to the central plunger-cylinder unit 16 in the form of double-acting hydraulic cylinders (Fig. 8).
    In Fig. 9 the operation of this adjusting unit 15 is made clear in a hydraulic diagram, wherein it is connected via a high-pressure filter 19 to suitable hydraulic drives 20, 20 ", 20". The hydraulic cylinders 17, 18 present in the area of the adjustment unit 15 are filled with hydraulic oil during assembly on the sides 21, 21 'of the ring piston thereof, so that a corresponding outgoing movement according to arrows 23, 23' is effected by the action of the in the area of the hydraulic piston side 22, 22 ', a piston side 24 of the plunger cylinder 16 is correspondingly pressurized and hence the movement in the direction of the arrow 25 occurs synchronously with the movement 23, 23'. Thus, a forced synchronization of the system by means of a master-slave connection has been obtained at low cost and in the area of the hydraulic control resp. - Drives 20, 20 ", 20" do not require expensive electronic position monitoring devices.
    Fig. 23 shows a hydraulic unit 52 forming the adjusting member 15 'and according to the type of a telescopic cylinder, wherein two telescopic lifting parts 54 and 55 are arranged in a base tube part 53 and co-operate with a cascade circuit.
    In the setting unit 15 'having the cascade circuit in accordance with Fig. 23, a shock-free lifting of the ship's steering housing 1 is obtained by means of the telescopic cylinder 52 from standstill. After operating a push button for lifting (at 56), the hydraulic drives 20, 20 ", 20" are switched on one after the other. As a result, the transport volume is increased with each additional connection and thus the lifting speed of the lifting device is continuously influenced. When the lifting process is interrupted, for example after reaching the intended position, the hydraulic drives 20, 20 ", 20" are switched off one after the other, so that a soft deceleration to the standstill is obtained.
    In order to also achieve a shock-free lowering of the ship's steering housing 1 from the relevant stationary position, the lowering valves of the hydraulic drives 20, 20 ", 20" are opened one after the other by pressing a button for lowering. As a result, the volume flow is increased with each switch-on process and thus the system lowering speed is continuously influenced. When this lowering process is interrupted, the lowering valves of the hydraulic drives 20, 20 ", 20" are closed one after the other, so that a gentle braking of the system to the standstill is achieved.
    This system with three hydraulic drives 20, 20 ", 20" also has a high safety standard, since in the event of a failure of one of the pumps, the lifting device 2 can also work with only two active pumps.
    With the maximum outward position of the lifting device 2 shown in fig. 4 it becomes clear that high demands are made on the guides in the area of the telescopic rails 7, 7 ', 7 ", 7", with regard to a minimum contact friction , low wear and optimum interchangeability. The relevant roller and / or friction combination in the area of the support bearings 9 must thereby be adapted to the manufacturing tolerances of the tubular bodies K, K "or. the relevant diameter deviations in areas D, D ", D" and for the long service life of the system, optimum compensation of weather influences is necessary, for example due to corrosion caused by this.
    Starting from the prototypes of conceivable "tube" tubular bodies K, K "shown in Figs. 10 and 11, a direct abutment of the mutually guided walls 6, 6 'is also conceivable, the aforementioned criteria of the requirements being, however, only with high costs can be met, since correspondingly high frictional forces are created and a "slip-stick effect" can occur as a result of the wear.
    With the embodiment of the lifting device 2 shown in Figs. 1 to 6, the control housing 1 can be moved over a suitable lifting path A, each of the tubular bodies K, K 'also allowing a lifting path of more than 1500 mm and thus for a wide variety of designs. a suitable system can be made available to ship bodies 3. With prototypes of the device 2 - starting from the basic length L of the structural components in the starting position - lifting heights A of more than 10 m have already been realized, so that the telescopic "round pipe system" can also be adapted to the requirements of a larger viewing range (A: more than 12 m conceivable) container ships or the like required in the wheelhouse 1.
    The symmetrical arrangement of four telescopic rail guides 7 to 7 '' with a relevant radial distance C becomes clear from the cross-sectional view according to Fig. 6, so that for the ship's steering house 1 schematically represented by dashed lines a support that is rotatable under wind load according to arrow W (arrow E) relative to the central upright axis H is obtained. The structural design of the telescopic rail guide 7 is thereby calculated to accommodate the rotational loads according to arrow E, whereby an additional rotational protection 14, 14 "(Fig. 20, Fig. 21) can also be integrated in the guide system. Moreover, the tubular structure K, K ", K" is stabilized in that groups of guides 7 with respect to groups of guides 7 are active at vertical distance U, U "(Fig. 7) (Fig. 7).
    Figs. 12 to 15 show, in enlarged cross-sections, an embodiment of parts in the area of the guide system, with the guide rails 26 (Fig. 4, Fig. 6) arranged adjacent to the profiles 8 being arranged. Building on this system, known per se as "armor rolls", a roller unit R was designed, wherein in a frame 29 having two parallel plates such bearing rollers 30 are arranged which, in the mounting position (fig. buses 32 are held. Additional run-on disks 33 located to the side are arranged in the area of the frame 29. It has been found that the roller unit R is particularly suitable as a bearing unit in the form of a metal-plastic-composite material group. This sliding resp. roller bearing reaches the suitable service life through a one-time filling of lubricant. The as sliding resp. The guide rail 26 (Fig. 14) provided on the roller partner has a low surface roughness, so that a low sliding resistance occurs and the wear in the area of the roller unit R and R, respectively. the supporting rollers 30 are so small that a high long-term stability is obtained with low maintenance intervals. To improve the above-described guidance, it is provided that the roller unit R can have a suspension swinging around an axis 34 (FIG. 12) (arrow P).
    In the figures 14 to 22, units R ', R ", R'" show other versions of pivotal protection 14, the support frame 29 for the rollers 30 having a respective intermediate plate 35 of elastomer having been accommodated in an outer frame 36 it is retained in the respective wall 6 of the tubular body K that a uniform pressing force (arrow F) towards the guide rail 26 is guaranteed. In the area of this guide rail 26, the system R "is formed by side guide pieces 37, 38 (FIG. 14) and FIG. 37 ", 38" (Fig. 15) extra protected against rotation E.
    In the embodiment according to Fig. 16 and Fig. 17, a guide unit N formed with slide plates 39, 40 is shown as a rotational protection with a vertical distance to the upper unit R, wherein relevant plastic layers 39 "and 40" are attached to the guide rails 26. In the embodiment according to Fig. 17 also the rotation protection N is shown, wherein here also additional adjustment elements for the above-lying roller unit R with a cover part 41 become clear and screws 42 related thereto are provided for adjusting the system (optimum pressure F). Fig. 18 shows the rotation protection 14 of the unit R 'similar to Fig. 14 with respective L-shaped mounting parts 43, 43' and Fig. 19 shows an embodiment similar to Fig. 14, with adjacent parts 37 "and 38" at a movement E 'about the axis V can be minimally displaced and an adjacent area Z, Z' (as also in Figs. 15 to Fig. 18) becomes effective.
    In a mounting position located at a radial distance T to the guidance system R "", the rotation guards 14 "according to Figs. 20 and 21 are shown. In FIG. 20, the twist guard 14 'is shown with an adjustment plate 22 attached to the tubular body K', a fastening shoe 45 cooperating with a sliding leg 46 inserted therein and secured to the tubular body K. In the embodiment according to FIG. guide strip 47 attached to tubular body K with respect to rollers 48, 49 present on tubular body K ', so that the relevant safety device of this fastening element is obtained in the direction of rotation E'.
    A particularly effective twist-protection-guide combination is shown in Fig. 22, in which a two tangentially directed abutment surfaces 50, 51 acting on rotation are arranged as guide part 26 ', so that the adjacent rollers 30 with vertical lifting movement of the system can also be active as parts of the twist protection 14 'at the same time.
