Description

[0001] Conveyor lifting device, especially for moving a heavy load, as well as a strand lifting system

[0002] The invention relates to a conveying lifting device, in particular for moving a heavy load, which has a drive unit and at least one conveying element driven by it with an adjusting means, wherein the adjusting means enables the respective heavy load to be adjusted by means of at least one controlled lifting movement, according to the preamble of claim 1 or claim 15.

[0003] Such conveying and lifting devices, particularly for moving heavy loads, are known and are characterized by their ability to lift, lower, or move heavy loads weighing over 10,000 tons over certain distances in order to assemble or dismantle these heavy loads. These conveying and lifting devices can be used for various purposes with different lifting, lowering, and moving operations, especially of heavy loads, such as for assembling bridge sections, roofs, building components, industrial plants, reactors, platforms, or the like.

[0004] The lifting system mounted in the supporting structure uses, for example, a strand jack system, which is also known per se. Such systems are very advantageous for lifting or carrying extremely heavy loads, and by using several of these systems pulling simultaneously, the heavy load can be lifted into the operating position.

[0005] Based on these known conveying lifting devices, the invention aims to further develop such a conveying lifting device in such a way that different conveying operations can be carried out with it, in order to utilize the conveying lifting device more universally and in a more targeted manner, thereby saving investment and maintenance costs.

[0006] This problem is solved according to the invention by the features of claim 1 and claim 15. According to the invention, several construction modules are assigned to the at least one conveying element with the adjusting means of the conveying lifting device, one of which can be mounted on a base structure of the conveying element or removed from it and replaced by another construction module, depending on the requirements for how the heavy load is to be moved.

[0007] With this arrangement of several building modules, the conveying lifting device can be changed from one mode of use to another through simple conversion work, without having to replace the entire conveying lifting device and transport it to the respective work location.

[0008] The basic structure of the conveying device is very advantageous, comprising at least one housing and an adjustment means that can be moved within it by one stroke, and it is designed in such a way that the various building modules can be mounted or functionally positioned on this one basic structure.

[0009] Thus, in a building module that can be mounted on the base structure, the adjustment mechanism of the base structure can be fitted with at least one support element attached to the same structure, on which the heavy load or a spacer element can be supported for its movement. This allows a heavy load to be supported directly or via spacers on the adjustment mechanism of the conveying device.

[0010] In another scenario, for example, after dismantling the described construction module, a new module can be installed in which the heavy load can be supported on at least one adjustment mechanism of the base structure via stackable spacer elements. Advantageously, a support structure, at least partially surrounding the base structure, is placed on the conveying element. This support structure can accommodate at least one spacer element, movable by the adjustment mechanism, which can then be lifted from the support structure by the next spacer element moved by the adjustment mechanism. This process can be repeated until the heavy load resting on the stackable spacer elements reaches the desired height. With this construction module, a heavy load can be advantageously lifted vertically over any distance from a few meters up to 100 meters.For example, it could be a roof structure that can be lifted from the ground to its predetermined height position by several conveying devices, each with this building module.

[0011] According to the invention, the support device enables the stackable spacer elements to be held after each lifting by the adjusting means, so that the adjusting means can be moved back to its starting position for lifting the next spacer element and the one above it.

[0012] These support devices for the building modules can be designed in various ways depending on the requirements of the conveying movement and the shape of the heavy load, which is a further advantage of the invention.

[0013] The basic structure of the conveying device is advantageously formed preferably by a piston / cylinder unit comprising a cylinder housing and a piston within the cylinder housing, adjustable by a stroke via the drive medium of the drive unit. In the majority of the modules, the heavy load is moved by a forward and backward movement of the piston, which, with the interposition of spacer elements, raises, lowers, or moves the heavy load horizontally and / or obliquely.

[0014] According to the invention, a strand lifting system is provided for a conveying lifting device, in which preferably two clamping devices can be mounted on the base structure of the conveying element in such a way that the preferably several strands which hold the heavy load can be clamped in and / or on the conveying element and can be moved in their longitudinal direction by one clamping device held by the adjusting means, by which the conveying element of the conveying lifting device is designed as a strand lifter.

[0015] With such a stranded lifting system as a building module, the heavy load can be moved, in particular by a pulling force, and this modularity according to the invention is achieved through simple assembly and disassembly thanks to the clamping devices that can be mounted on the base structure.

[0016] The invention and further advantages thereof are explained in more detail below with reference to exemplary embodiments and the drawing. It shows:

[0032] The conveying element 10 of a conveying lifting device 15, shown in Figures 1 to 7, is used in particular for moving a heavy load, as illustrated in Figure 6. The heavy load can be conveyed, for example, in a basket-like container 16, which can accommodate corresponding heavy loads. These heavy loads can be industrial machines, building components, or any heavy loads to be lifted or lowered, which generally have a weight or size that cannot be handled with conventional lifting equipment.

[0033] According to Fig. 6, the conveying lifting device 15 can be installed either permanently, for example on the roof 14 of a building 13 (indicated), or only temporarily for transporting one or more heavy loads. It consists of a container 16, a drive unit 18, two strand jacks 10 driven by the drive unit as conveying elements, and longitudinal elements 19 which hold the container 16 for conveying and are operatively connected to the conveying element 10. The latter is fixedly positioned by a support 17 attached to the roof 14 and projecting from the building 13, so that the container 16 with the heavy load can be lifted at a distance from the outer wall.

[0034] According to the invention, the conveying element 10 is provided with a base structure 20, which is designed as a piston-cylinder unit with a cylinder housing 21 and a piston 25, adjustable therein by a stroke by the drive medium of the drive unit 18, as an adjusting means. A construction module can be mounted to or removed from this base structure 20 of the conveying element 10, which, according to Fig. 2, consists of clamping devices 11, 12, by which the heavy-load-holding longitudinal elements 19 can be clamped in the conveying element 10 and are movable in their longitudinal direction by one of the clamping devices 12, which is held by the piston 25 as an adjusting means. By means of this, the conveying element is designed as a strand lifter, by means of which the container 16 with the heavy load can be raised or lowered via these longitudinal elements 19, which are preferably designed as strands.

[0035] Both the conveying element 10 and the other conveying elements described below utilize the same basic structure 20, which consists of the piston-cylinder unit with the cylinder housing 21 and the adjustable piston 25. A clamping device 12, mounted on the upper side of the piston 25, and a clamping device 11, mounted on the underside of the cylinder housing 21, can be attached to this basic structure 20. These clamping devices are designed to be removable as one of the possible modular components. The piston 25 is designed as an annular piston, and one or more through-openings 26 are provided in it and in the clamping devices 11 and 12 for the passage of the preferably multiple longitudinal elements 19, the longitudinal axes of which are shown with dashed lines in Fig. 3.Between the cylinder housing 21 and the ring piston there is a ring chamber 27, which is connected to the hydraulic or pneumatic drive unit 18 by means of connections 22 and into which the drive medium, preferably an oil, can be supplied at the necessary pressure.

[0036] These clamping devices 11, 12 are identical in design, and only one is described in detail below. Appropriate reference numerals are used for the same parts. The lower clamping device 11 is arranged in a frame-shaped structure 31, which has a support flange 32, 33 on both its upper and lower sides. The lower flange serves as a support for the conveying element 10, and the upper flange serves as a connecting element to the base structure 20.

[0037] In an enlarged section of the lower clamping device 11 according to Fig. 4, a base plate 28 is provided, fastened in the frame 31 by means of bolts or the like, with through-openings 26 for the longitudinal elements 19. A clamping wedge 34 extends into each of these through-openings 26, which is attached at the top to a retaining element 35 adjustable in the direction of the longitudinal axes 19. This retaining element 35 can be actuated into an open or closed position by a bracket 36 and a switching element 36', so that in the lower closed position the clamping wedges 34 clamp the longitudinal elements 19 in each through-opening 26 in the transverse direction, while in the open position, in which the clamping wedges are adjusted upwards, the longitudinal elements 19 are released and movable in their longitudinal axis 19.The segment-shaped clamping wedges 34 and the corresponding through-openings 26 each extend conically in the direction of the longitudinal axis 19, while the clamping wedges are cylindrical on the inside and the through-openings are cylindrical on the opposite side. This results in a flat contact surface between them and the longitudinal elements 19 when clamped.

[0038] Furthermore, a compression spring 37 can be arranged at the top of the retaining element 35, by which these clamping wedges 34 are always moved into the closed position for safety reasons, while to open this switching element 36' pivots the bracket 36 downwards and this moves the retaining element 35 upwards and releases the clamping wedges 34.

[0039] Fig. 5 shows the upper clamping device 12, including the bracket 36 with the switching element 36* that actuates it externally and the retaining element 35 to which the bracket is hinged internally. A number of through-openings 26 are visible, such as seven, although this can vary depending on the requirements. Furthermore, a guide element 39 is advantageously attached to the outside of the cylinder housing 21, on which a guide part 38 slides on the piston 25, thus securing the piston against rotation and ensuring its safe guidance in the extended position.

[0040] As mentioned, the two clamping devices 11 and 12 are identical in design, and therefore the upper one is not described in detail again. It should merely be noted that this upper clamping device 12 has a lower flange 42 for a detachable attachment to the upper end face of the piston 25 as an adjustment means, and a guide cage 41 on its upper side for the longitudinal elements 19, so that these are inserted straight into the upper clamping device 12 along their longitudinal axes 19* when lowered. These longitudinal elements 19 can be stored above the conveyor, for example on rollers or reels, which is not shown in detail.

[0041] Of course, more than two of these clamping devices could be provided depending on the weight to be lifted or the safety requirements, and the number of conveying elements can also be varied as desired, although in normal cases it is sufficient if they are supplied by one drive unit.

[0042] The adjusting means provided as piston 25, through controlled forward and backward movements by the respective total stroke in conjunction with a controlled alternating opening and closing of the two clamping devices 11, 12, causes an adjustment of the heavy load, as is explained below by the individual steps:

[0043] As mentioned, a clamping device 11, 12 with radially adjustable clamping wedges 34 is provided at the upper end of the piston 25 and at the lower end of the cylinder housing 21, respectively, for alternately holding the longitudinal element(s) 19. When pulling a heavy load held by the longitudinal elements, the clamping device 12 at the top of the piston holds the longitudinal elements 19 firmly in place when the piston 25 is retracted, as shown in Fig. 3. The drive unit 18 then forces the drive medium into the annular chamber 27 in the cylinder housing 21, causing the piston 25 and the held longitudinal elements 19 to move upwards. Once the piston 25 has extended through its full stroke, the open clamping wedges 34 of the fixed clamping device 11 are closed, and those on the piston 25 are opened. The piston 25 is then retracted, while the longitudinal elements 19 remain stationary.This process is repeated until the heavy load to be lifted reaches its final position. The control during lifting of the heavy load by the two preferably identically designed conveying elements 10 is synchronously coordinated, which can be achieved by pressure equalization at the drive unit 18 to ensure an even load distribution.

[0044] It goes without saying that, conversely, lowering the container 16 with the conveying lifting device 15 according to Fig. 4 is equally possible, which is not explained in detail here. Accordingly, the individual steps of the lowering process would have to proceed in reverse order, whereby the longitudinal elements 19 would also be lowered by controlled forward and backward movements of the piston through the respective total stroke in conjunction with a controlled alternating opening and closing of the two clamping devices 11, 12, whereby the upper clamping device 12 would, conversely, close when the piston 25 retracts and pull the longitudinal elements downwards with it.

[0045] This conveying lifting device 15 could also be used for pulling a heavy load in a horizontal or oblique direction. The longitudinal elements 19 and with them the at least one conveying element 10 would be arranged such that the longitudinal axes 19' would preferably be aligned coaxially with the pulling direction. Otherwise, this conveying lifting device 15 would function in the same way as described above, in which, according to the invention, the base structure 20 and this module mounted on it with the clamping devices 11, 12 would be used.

[0046] Figures 8 and 9 show a conveying lifting device 45 for repositioning a heavy load, in which, unlike the device shown in Figure 6, this heavy load is lifted or moved by stackable spacer elements 49. The heavy load is, for example, a roof-shaped dome 46, which is schematically illustrated, or the like, which is lifted to a desired height from a base 43. Four conveying elements 40 can be used as examples in the corner areas of the dome 46, and of course, additional conveying elements could be placed depending on the load weight and its design.

[0047] According to the invention, each conveying element 40 is again assigned a construction module as one of the mountable construction modules, which is suitable for the illustrated use. The construction module is a support device 44 surrounding the base structure 20 of the conveying element 40, on which a spacer element 49, movable by the adjusting means of the base structure 20 by one stroke, can be supported and lifted from the support device 44 by the next spacer element 49 moved by the adjusting means. In this box-shaped support device 44 with a lateral access opening 44', this base structure 20 with the cylinder housing 21 and the piston 25, which is displaceable therein by the drive unit 18, is advantageously fastened.

[0048] Advantageously, a passage 44" is provided on the upper side of the support device 44, with a locking device 47 mounted laterally on a base 52. These locking devices 47 each have one or more locking elements 48 that are displaceable transversely to the respective spacer element 49 by a controllable adjustment motor 51. These locking elements 48 engage corresponding locking elements of the spacer element 49 after the latter's stroke movement, thus fixing the spacer element in place. These locking elements 48 are designed as locking pins 48' and corresponding bores or the like in the spacer element 49. They are arranged to be displaceable by a control system or manually, and they enable the spacer element 49 to be fixed in place after the stroke has been reached.Of course, only one such locking device 47 could be provided and it could also be designed differently than shown, for example by a pivoting part that releasably engages in a slot in a respective spacer element 49.

[0049] After a spacer element 49 is inserted into the lateral access opening 44' of the support device 44 and moved upwards by the piston 25, it is secured by the locking means 47. This allows the piston 25 to retract downwards into the cylinder housing 21 without the spacer element 49, and another spacer element 49 to be inserted laterally and moved upwards. Before this happens, the locking means 47 of the raised spacer element 49 are released, so that both spacer elements are moved upwards by the stroke. Advantageously, the stacked spacer elements 49 are fixed, for example, by lateral longitudinal rails 53. They could also be secured to each other by screws or similar fasteners. This process is repeated until the heavy load on the stacked spacer elements 49 has reached the desired height or distance.

[0050] Fig. 8 shows that several such spacer elements 49 are already stacked on top of each other at each conveying element 40, which is done simultaneously at all conveying elements so that the dome 46 moves stepwise upwards with its plane in a horizontal orientation.

[0051] With this conveying lifting device 45, it is also possible for the heavy load to be lowered, in which a reverse process would take place, in which the lowered spacer elements 49 can be removed one after the other from this lateral access opening 44' of the support device 44.

[0052] Furthermore, this conveying lifting device 45 also enables the pushing of a heavy load in a horizontal or oblique direction. The spacer elements 49, and with them the at least one conveying element 10, would be arranged such that the adjustment direction of the piston 25 would preferably be coaxial with the displacement direction of the heavy load. This conveying lifting device 45 would function in the same way as described above.

[0053] The insertion of the spacer elements 49 into this lateral access opening 44' of the support device 44 and the locking or unlocking of the spacer elements 49 by the locking means 47 could be automated by a manipulator or the like. The individual steps, as explained above, could be controlled by a control unit at the drive unit 18, which can be connected to the piston / cylinder units by means of appropriate cable guides 18'. For feeding the spacer elements 49 into the support devices 44, they could be stored in containers and conveyor belts or similar devices and easily inserted individually.

[0054] Fig. 10 shows a conveying element 50, which differs from the conveying element 40 with the support device 44 described above only in that a support device 54 surrounding the base structure 20 is provided as a modular unit. This support device does not have locking means 47, but rather several supports 55 arranged around its circumference on its upper side. These supports 55 are movably mounted on the support device 54 in such a way that a spacer element 59, which can be moved by the adjusting means, can be supported. These supports 55 of the support device 44 are arranged to pivot or be adjustable transversely to the respective spacer element 59 and can be pressed against a respective spacer element 59 by an impact force, which is not shown in detail. After an adjustment travel, these supports 55 are arranged to engage automatically with a corresponding locking means of the spacer element 59 and cause the latter to be temporarily fixed on the support device 54.Each of the spacer elements 59 is assigned a hub 59* on its outer circumference as a locking device.

[0055] The supports 55 are automatically adjusted at their upper ends 55' outwards by the upward movement of the next spacer element 59 and consequently back inwards to support it from below at the respective hub 59'. A known tension or compression spring can be arranged as the impact force for this locking and unlocking of the supports 55, whereby the supports could, for example, be pivotably held at a base plate 58 of the support device 54 and their upper ends 55* could be pivoted radially outwards.

[0056] In this box-shaped support structure 54 with a lateral access opening 57 for the spacer elements 59, this base structure 20 with the cylinder housing 21 and the piston 25, which is movable therein by the drive unit 18, is advantageously attached as an adjusting means. An attachment 56 is also mounted on the piston 25, by means of which a respective spacer element 59 can be inserted into this lateral access opening 57 in the correct height position, and above this, as shown, is the spacer element 59, which has already been moved upwards and is supported by the supports 55. This process of insertion and lifting can be repeated as often as necessary until a heavy load assumes the predetermined position, whereby horizontal or oblique sliding of the load would also be possible.

[0057] Figures 11 and 12 show a lifting device 65 for positioning a heavy load 66 on rails 61 in the horizontal direction of arrow H. This heavy load 66 can be a schematically shown bridge section of a bridge to be built, which is constructed from several such bridge sections joined together. A drive unit (not shown in detail) and several conveying elements 60 driven by it, each with an adjustment mechanism, enable the respective heavy load to be positioned by means of a controlled lifting movement. For example, three such conveying elements 60 are placed on each side of the rails 61 below the heavy load 66; the number of these elements can be smaller or larger. Advantageously, recesses 64 are formed on the underside of the heavy load 66, in which at least one conveying element 60 can be placed.

[0058] The basic structure of the conveying element 60 is formed, as in the above embodiment examples, by a piston-cylinder unit, which has a cylinder housing 21 and a piston 25 in the cylinder housing 21 which can be adjusted by a stroke by the drive medium of the drive unit.

[0059] According to the invention, each conveying element 60 with the adjusting means is assigned a construction module which can be mounted on or removed from the base structure of the conveying element 60. This construction module can be exchanged accordingly for other uses, such as according to Fig. 8.

[0060] The assembly module consists of at least one base 62, which is attached below the cylinder housing 21, and at least one support plate 63 on the piston 25. The lower base 62 is dimensioned such that it is guided in the respective rail 61, the latter preferably being a so-called sliding track that exhibits good sliding properties when guiding the base 62. The horizontal displacement of the heavy load 66 could, for example, be effected by the conveying lifting device 15 or 45. Fig. 13 shows a similar assembly module on the base structure 20 as that shown in Fig. 12, in which a base 68 is attached below the cylinder housing 21 and a connecting piece 69, which can be placed on the piston 25, is provided. The connecting piece 69 has a centering element 69' projecting into the through-opening 26 of the piston 25.Such training of the lifting device is suitable, for example, for lifting a platform in the offshore sector.

[0061] Figures 14 and 15 show a variant of a conveying lifting device 75 for adjusting a heavy load 76, for which support beams 76' of a gable roof 76 are indicated. For the uniform lifting of this gable roof 76, a conveying element 70 of the conveying lifting device 75 is assigned to each of the respective support beams 76' on both sides, functioning similarly to the one shown in Figure 8. Therefore, only the differences are described below.

[0062] According to the invention, a support structure 74 surrounding the base structure 20 of the conveying element 70 is provided as a building module. A spacer element 79, movable by a stroke by the adjusting means of the base structure 20, can be supported on this support structure 74 and lifted off by the next spacer element 99 moved by the adjusting means. This base structure 20, with the cylinder housing 21 and the piston 25, which is displaceable therein by the drive unit 18 (not illustrated), is advantageously attached to this support structure 74, which forms a frame and has a lateral access opening 74'.This support structure 74 consists of profile-shaped support feet 76, 77, guide profiles 73 perpendicular to these, and elongated reinforcing elements 78, which are attached to the outside of the support feet 76, 77 and to the upper end of the guide profiles 73 to stiffen the latter, so that the support structure 74 is sufficiently stable overall. This support structure 74 could, of course, be designed differently than shown, for example as a box shape according to Fig. 9 or something similar.

[0063] An opening 73' is formed between the guide profiles 73, through which the spacer elements 79 are guided and outwards at the top. The spacer elements 79 are also inserted laterally between the guide profiles 73 when one of the upper guide profiles is held and the piston is retracted into the cylinder housing, which is not shown, but can be done as in the conveying lifting device according to Fig. 9 or Fig. 10. The profile-shaped support feet 76, 77 and these guide profiles 73 could consist of the same profiles as the spacer elements 79, as shown, so that only such profiles would need to be used, which would offer logistical advantages.

[0064] Figures 16 and 17 show a conveying lifting device 85 for adjusting a heavy load 76, which is preferably directly supported on at least one adjustment means of the base structure 20. A support pillar 88 is also indicated, on which the heavy load, for example as a road bridge component, is to be supported in its assembled state. The heavy load is not lifted by this conveying lifting device 85, but, after lateral feeding as shown, is lowered onto the supports 88'. Two conveying elements 80 are arranged side by side with the base structure 20, and, as a building module within the scope of the invention, a support device 84 is provided that supports on both sides or partially surrounds the conveying elements 80. This support device is formed by spacer elements 89 stacked on top of each other on two opposite sides of the conveying elements 80.The upper bearing surfaces of the adjusting means of the conveying elements 80 and the spacer elements 89 are aligned flush with each other and the heavy load 86 rests on these four bearing surfaces in the stationary state or at least on those of the stacked spacer elements 89.

[0065] The conveying elements 80 consist of the cylinder housing 21 and the piston 25 as an adjusting means. Advantageously, at least one support plate 83 is attached to the top of the piston 25. The heavy load 86 is briefly moved upwards by the two pistons 25 as adjusting means, so that it is lifted off the spacer elements 89 and at least one spacer element can be removed on each side, as indicated in Fig. 17, in order to lower the heavy load in stages. This process is repeated until the heavy load is lowered onto the supports 88' of the support pillar 88.

[0066] The adjusting mechanism of the respective base structure is advantageously almost fully extended in the state before the heavy load 86 is lowered and, after the heavy load is raised and one spacer element is removed from each side, can be moved backwards until the heavy load 86 rests on the stacked spacer elements. Depending on the overall height of the subsequent lowering of the heavy load 86, the conveying elements 80 preferably also rest on stacked spacer elements 89, as illustrated in Fig. 17. These spacer elements 89 can then also be removed individually when the adjusting mechanisms of the conveying elements 80 are not loaded and the heavy load rests on the spacer elements 89 at the support device 84.

[0067] When the heavy load 86 is lifted to a certain height by the conveying elements 80, the heavy load is also lifted off the spacer elements 89, and at least one spacer element 89 can then be placed on the stack of spacer elements on both sides below the heavy load, and this can be repeated until the heavy load is lifted to the desired height.

[0068] The respective conveying lifting devices can be equipped with one of the various construction modules for different lifting and shifting operations, as explained in detail above, particularly for heavy loads. These heavy loads can include, for example, bridge sections, roofs, building components, industrial plants, reactors, platforms, or similar items that can be adjusted in height or length. The heavy load can, of course, also consist of several partial loads.

[0069] It can be a hydraulic and / or pneumatic drive unit equipped with appropriate motors or pumps and control devices.

[0070] This provides a further advantage within the scope of the invention, namely that the conveying lifting devices with the various construction modules can be operated with the one drive unit and the control device, and that a separate control device or drive unit does not have to be used for each conveying lifting device.

[0071] The control unit for the drive unit is designed to be program-controlled in such a way that the conveying elements can be operated with a single basic structure for all building modules. This is a further advantage of the invention, as it eliminates the need for a separate control unit for each conveying system. For this purpose, the control unit is programmed to control the corresponding processes of the various conveying systems for the basic structure with the adjustment mechanism for all building modules, as shown in the figures and explained above. These processes are mostly achieved by adjusting the adjustment mechanism, and thus the conveying elements, in stages.

[0072] In principle, more than one conveying element could be provided, and instead of a piston-cylinder unit, a different conveying element could be provided, such as a rack that is longitudinally adjustable by at least one pinion instead of a piston.

[0073] In a strand jack, the longitudinal elements could also run laterally to the housing in the adjustment direction of the adjusting means.
