Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and specifically to a prefabricated cabin-mounted overhead crane gripper mechanism. Background Technology

[0002] Prefabricated GIS and other equipment require lifting, short-distance transport, and placement during installation and maintenance. Due to limited space inside the cabin and the fact that most of the equipment has a cylindrical or curved structure, existing technologies face two main problems during transportation: I. Existing solutions mostly use slings, wire ropes for direct binding, or simple lifting devices for suspension. The support and clamping are independent of each other, and the force path is prone to drift. This leads to the need for manual traction and repeated adjustments for alignment, making it difficult to guarantee the posture stability and positioning reliability during transportation.

[0003] Second, some clamps achieve clamping through hydraulic, electric or manual screws, but they are usually large in size and have many adjustment steps, making them difficult to arrange in the low clearance and narrow passage of the prefabricated cabin; at the same time, their ability to fit equipment of different diameters / shapes is limited, which can easily lead to problems such as insufficient clamping causing slippage or excessive clamping causing surface damage. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the purpose of this invention is to provide a prefabricated cabin gantry crane gripper mechanism to solve the problems of poor linkage between support and clamping actions and insufficient reliability of clamping and positioning during the transportation of equipment in the prefabricated cabin.

[0005] To achieve the above objectives, the present invention provides a prefabricated cabin in-cabin overhead crane gripper mechanism, comprising: Supporting components that support the equipment to be transported from below; A clamping assembly, positioned above the supporting assembly, presses the device to be transported from above; and A guide adjustment assembly is symmetrically arranged at both ends of the clamping assembly and the supporting assembly; The guide adjustment assembly includes a linkage module movably connected to the clamping assembly and a slider module movably connected to the supporting assembly; Under the weight of the equipment to be transported, the supporting component moves the slider module downward and drives the connecting rod module to move the clamping component downward according to a preset stroke ratio to cooperate in approaching and clamping the equipment to be transported.

[0006] Furthermore, the overhead crane gripper mechanism also includes a load-bearing frame; The load-bearing frame includes: An inverted U-shaped hanger, comprising a horizontal beam and vertical columns disposed at both ends of the horizontal beam; and A connecting plate, located between the crossbeams of the two hangers; The upper surface of the crossbeam is provided with at least one lifting ring, and the lower part is provided with sliding columns located at both ends of the clamping assembly.

[0007] Furthermore, the slider module includes: The guide seat is fixedly installed on the column in the bearing frame, and the guide seat has a fixing block on the side near the clamping assembly and a guide hole at the bottom; A slider, which is disposed within a sliding groove in the guide seat and slides vertically along a guide post disposed within the sliding groove; and A guide element, comprising a pair of guide posts arranged on both sides of the guide post; The top ends of the two guide posts are connected to the bottom of the slider, and the bottom ends pass through the guide holes and extend to provide connecting blocks.

[0008] Furthermore, the linkage module includes: The first connecting rod has one end rotatably connected to the slider in the slider module; The second link, one end of which is rotatably connected to the clamping assembly; and The proportional connecting rod is movably connected to the fixed block through a fixing hole at one end, and rotatably connected to the second connecting rod at the other end; The proportional connecting rod is a strip plate, and hinge holes are equally spaced on the proportional connecting rod; the other end of the first connecting rod is movably connected to the proportional connecting rod through one of the hinge holes.

[0009] Furthermore, the center distance from the fixing hole to its nearest hinge hole is a first distance, and the center distance from the fixing hole to its farthest hinge hole is a second distance; the first distance and the second distance are set in a predetermined ratio to limit the preset stroke ratio.

[0010] Furthermore, the clamping assembly includes: An arc-shaped saddle beam, with connecting seats at both ends that are rotatably connected to the second connecting rod in the connecting rod module; and At least two clamping modules are installed at equal intervals on the arc-shaped saddle beam, forming multi-point clamping on the outer surface of the equipment to be transported; The arc-shaped saddle beam has an extension block on its inner arc-shaped side that corresponds to the clamping module, and the connecting seats at both ends are fitted onto the sliding column. The lower part of the sliding column has several limiting holes along the vertical direction, and the bottom end has a limiting block. The limiting block is installed at the limiting holes at different heights to adjust the displacement stroke of the arc-shaped saddle beam as it reciprocates along the sliding column.

[0011] Furthermore, the clamping module includes: The adjusting component includes a locking screw threadedly connected to the arc-shaped saddle beam, an upper push plate disposed at the lower end of the locking screw, and a push rod coaxially connected to the upper push plate. An extrusion component, comprising a sleeve fitted over the outside of the push rod and a lower push plate disposed at the lower end of the sleeve; An elastic element, sleeved on the outside of the sleeve, has its two ends abutting against the upper push plate and the lower push plate, respectively; and The pressure plate is connected to the lower push plate via a ball joint with a ball joint rod. The lower end of the ball head rod is fixedly connected to the pressure plate, and the upper ball head is embedded in the ball socket of the lower push plate; one side of the pressure plate is provided with a flexible pad that contacts the outer surface of the equipment to be transported.

[0012] Furthermore, the clamping module also includes a limiting member disposed in the annular groove at the bottom end of the extension block; The annular groove has a keyway extending axially on its wall, and the outer periphery of the limiting member has a key that mates with the keyway. The limiting member has several adjustment holes along the axial direction, the extension block has a connecting hole, and the relative distance between the limiting member and the pressure plate is limited by a locking member that is sequentially inserted into the connecting hole and any of the adjustment holes.

[0013] Furthermore, the support component includes: The base, located below the clamping assembly; and A traction module is installed in pairs at both ends of the base and drives the base to move to support the equipment to be transported.

[0014] Furthermore, each of the traction modules includes: A pulley frame, which is fixedly connected to the connecting block in the slider module; A pulley, which is rotatably connected to the pulley frame via a pulley axle; A wire-feeding mechanism, located below the pulley frame, and fixedly mounted on the column; and The traction rope has one end connected to the wire-laying mechanism and can be retracted and extended with the wire-laying mechanism, and the other end is connected to the base after passing through the pulley.

[0015] Beneficial effects: This invention sets a support component below the equipment to be transported and a clamping component above it, with guide adjustment components at both ends. During short-distance transport, transfer, and positioning of the equipment within the prefabricated compartment, the weight of the equipment to be transported, through the support component, causes the slider module to shift, which in turn drives the linkage module to press down in a preset stroke ratio, making the clamping component and the support component relatively close to form an upper and lower clamping, achieving adaptive clamping positioning. The guide adjustment components are symmetrically set at both ends and work together to reduce the force drift and repeated alignment adjustments caused by the independent support and clamping, reduce the risk of posture deviation and loosening during transportation, and improve the stability and safety of equipment transportation and positioning.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1: like Figure 1 As shown, this embodiment provides a prefabricated cabin in-cabin overhead crane gripper mechanism, including: a support component 1, which supports the equipment to be transported from below; a clamping component 2, which is located above the support component 1 and presses the equipment to be transported from above; and a guide adjustment component 3, which is symmetrically arranged at both ends of the clamping component 2 and the support component 1; wherein, the guide adjustment component 3 includes a connecting rod module 31 movably connected to the clamping component 2 and a slider module 32 movably connected to the support component 1; under the action of the gravity of the equipment to be transported, the support component 1 drives the slider module 32 to move downward, and drives the connecting rod module 31 to move the clamping component 2 downward according to a preset stroke ratio to cooperate in approaching and clamping the equipment to be transported.

[0021] During operation, the overhead crane mechanism is connected to the prefabricated container overhead crane 5, with the clamping component 2 positioned above the equipment to be transported and the supporting component 1 positioned below it. During the transfer process, the supporting component 1 first contacts the lower part of the equipment to be transported and supports it. The weight of the equipment acts on the supporting component 1, causing it to undergo relative displacement under the constraint of the guide adjustment component 3. This displacement is transmitted to the connecting rod module 31 via the slider module 32. The connecting rod module 31 converts the displacement of the supporting component 1 into the downward clamping displacement of the clamping component 2. The downward movement distance of the clamping component 2 is greater than that of the supporting component 1, thereby reducing the relative distance between the clamping component 2 and the supporting component 1 according to a preset stroke ratio. The two components work together to approach each other and form an upper and lower clamping fit with the equipment to be transported, achieving clamping and positioning.

[0022] like Figures 1 to 3 As shown, the mechanism also includes a support frame 4. The support frame 4 includes a pair of inverted U-shaped hangers 41 and a connecting plate 42. Each inverted U-shaped hanger 41 includes a crossbeam 411 and vertical columns 412 at both ends of the crossbeam 411; the connecting plate 42 is located between the crossbeams 411 of the two inverted U-shaped hangers 41 and is used to connect the two hangers 41 into an integral frame. The upper surface of the crossbeam 411 is provided with at least one lifting ring 43 for connection with the hook of the prefabricated cabin crane 5; the lower part of the crossbeam 411 is provided with sliding columns 44 located at both ends of the clamping assembly 2 for guiding the vertical movement of the clamping assembly 2 and cooperating with the limiting structure described later to achieve stroke adjustment, wherein the distance between the two sliding columns 44 is greater than the diameter or width of the equipment.

[0023] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, each guide adjustment assembly 3 includes a slider module 32. The slider module 32 includes a guide seat 321, a slider 323, and a guide member 325.

[0024] The guide seat 321 is fixedly mounted on the column 412. A fixing block 322 is provided on the side of the guide seat 321 near the clamping assembly 2. The bottom of the guide seat 321 has a guide hole and a sliding groove inside. A guide post 324 is provided in the sliding groove. The slider 323 is disposed in the sliding groove and slides vertically along the guide post 324 to obtain stable linear guidance and provide controllable displacement input for the subsequent connecting rod module 31. Optionally, friction pads are provided on both sides of the sliding groove. The friction pads are in contact with the sides of the slider 323 to provide damping during the downward movement of the slider 323 to buffer the descent speed.

[0025] The guide 325 includes a pair of guide posts 3251 located on both sides of the guide post 324. The top ends of the two guide posts 3251 are connected to the bottom of the slider 323, and the bottom ends of the two guide posts 3251 pass through the guide hole and extend downward to form a connecting block 3252.

[0026] In addition to the vertical displacement input provided by the slider module 32, each guide adjustment component 3 also includes a linkage module 31, which converts the input into the output displacement of the clamping component 2 according to a preset stroke ratio. The linkage module 31 includes a first linkage 311, a second linkage 312, and a proportional linkage 313.

[0027] One end of the first connecting rod 311 is rotatably connected to the slider 323; one end of the second connecting rod 312 is rotatably connected to the clamping assembly 2; one end of the proportional connecting rod 313 is movably connected to the fixed block 322, and the other end is rotatably connected to the second connecting rod 312. The proportional connecting rod 313 is a strip plate with several hinge holes 314 evenly spaced along its length. The other end of the first connecting rod 311 is movably connected to the proportional connecting rod 313 through one of the hinge holes 314.

[0028] For ease of description, in this embodiment, the hole corresponding to the connection position between the proportional connecting rod 313 and the fixed block 322 is defined as the fixed hole 3131. The center distance from the fixed hole 3131 to the nearest hinge hole 314 is the first distance, and the center distance from the fixed hole 3131 to the farthest hinge hole 314 is the second distance; the first distance and the second distance are set according to a predetermined ratio to limit the preset stroke ratio.

[0029] The following describes the implementation of the proportional change: The proportional link 313 uses the hinge point between the fixed hole 3131 and the fixed block 322 as an equivalent rotation reference. The vertical displacement generated by the slider 323 within the guide seat 321 serves as the input displacement, which is transmitted to the proportional link 313 via the first link 311. The other end of the first link 311 can selectively connect to the proportional link 313 through different hinge holes 314, thereby changing the center distance of the hinge hole 314 relative to the fixed hole 3131, i.e., the position of the input point of the first link 311 relative to the proportional link 313. The hinge end of the proportional link 313 and the second link 312 serves as the output end, and the vertical displacement of this output end serves as the output displacement, which is further driven by the second link 312 to cause the clamping assembly 2 to move vertically downward.

[0030] Because the center distances from different hinge holes 314 to the fixed hole 3131 are different, under the same input displacement conditions, the rotation angle generated by the proportional link 313 around the fixed hole 3131 is different, resulting in different output displacements at the output end. Consequently, the downward movement of the clamping component 2 relative to the downward movement of the supporting component 1 forms different stroke ratios. Specifically, when the hinge hole 314 closer to the fixed hole 3131 is connected to the first link 311, the rotation angle of the proportional link 313 is relatively increased, the output displacement at the output end is relatively increased, and the downward movement of the clamping component 2 is relatively increased. When the hinge hole 314 farther from the fixed hole 3131 is connected to the first link 311, the rotation angle of the proportional link 313 is relatively decreased, the output displacement at the output end is relatively decreased, and the downward movement of the clamping component 2 is relatively decreased. By switching the positions of the hinge holes 314 of the first link 311 and the proportional link 313, the preset stroke ratio can be adjusted in stages without changing the link length to adapt to transport equipment with different external dimensions or clamping stroke requirements.

[0031] Under the output action of the linkage module 31, the clamping assembly 2 achieves clamping of the top of the equipment. For example... Figures 2 to 4 as well as Figure 7 As shown, the clamping assembly 2 includes an arc-shaped saddle beam 21 and at least two clamping modules 23. The two ends of the arc-shaped saddle beam 21 are connecting seats 22 that are rotatably connected to the second connecting rod 312, used to transmit the output displacement of the connecting rod module 31 as a vertical downward clamping motion of the arc-shaped saddle beam 21. The clamping modules 23 are evenly spaced on the arc-shaped saddle beam 21 to form multi-point clamping on the outer surface of the equipment to be transported, thereby improving clamping stability and reducing the risk of localized crushing damage.

[0032] The connecting seats 22 at both ends of the arc-shaped saddle beam 21 are fitted onto the sliding column 44. Several limiting holes 441 are opened vertically at the lower part of the sliding column 44, and a limiting block 24 is provided at the bottom of the sliding column 44. The limiting block 24 is installed at the limiting holes 441 at different heights to adjust the displacement stroke of the arc-shaped saddle beam 21 reciprocating along the sliding column 44, thereby adapting to different equipment heights or clamping stroke requirements.

[0033] The arc-shaped saddle beam 21 is integrally formed with an extension block 211, which is arranged one-to-one with each clamping module 23. The arc-shaped saddle beam 21 and its integrally formed extension block 211 are axially perforated with sequentially connected threaded holes, receiving holes, and guide holes; wherein the diameter of the threaded holes is the same as the diameter of the guide holes, and the diameter of the receiving holes is larger than the diameters of the threaded holes and guide holes. This three-hole coaxial through structure is used to install the adjusting component 231 and the pressing component 232 of the clamping module 23 and provides guiding and receiving space, ensuring stable transmission of clamping force, compact assembly structure, and ease of maintenance and replacement.

[0034] like Figure 7 and Figures 10 to 14As shown, each clamping module 23 consists of an adjusting component 231, a pressing component 232, an elastic component 233, and a pressure plate 234, arranged along the same axis to form a continuous clamping force transmission path. The adjusting component 231 includes a locking screw 2311, an upper push plate 2312, and a push rod 2313. The locking screw 2311 is threadedly connected to the threaded hole of the arc-shaped saddle beam 21. The upper push plate 2312 is located at the lower end of the locking screw 2311, and the push rod 2313 is coaxially connected to the upper push plate 2312. The pressing component 232 includes a sleeve 2321 and a lower push plate 2322. The sleeve 2321 is fitted onto the outside of the push rod 2313 and slides with the push rod 2313. The lower push plate 2322 is fixedly located at the lower end of the sleeve 2321. The elastic component 233 is fitted onto the sleeve 2321. 1. On the outside, its two ends abut against the upper push plate 2312 and the lower push plate 2322 respectively, so as to generate controllable elastic compression when the locking screw 2311 is adjusted; the pressure plate 234 is ball-jointed to the lower push plate 2322 through the ball head rod 2341. The lower end of the ball head rod 2341 is fixedly connected to the pressure plate 234, and the upper ball head is embedded in the ball socket of the lower push plate 2322, so that the pressure plate 234 can realize angle swing when axial force is transmitted to adaptively fit the outer surface of the equipment to be transported. The side of the pressure plate 234 facing the equipment is provided with a flexible pad 235 to improve the fitting and protection effect.

[0035] Combining the aforementioned three-hole coaxial through structure: the locking screw 2311 is located inside the threaded hole and is threaded into it; the upper push plate 2312, push rod 2313, sleeve 2321, elastic element 233, and lower push plate 2322 are all arranged inside the receiving hole to obtain sufficient compression and buffer stroke; wherein, the push rod 2313 slides axially within the sleeve 2321 to transmit and balance the axial load; the hinge area of ​​the ball socket and ball head rod 2341 is correspondingly located at the guide hole. By tightening or loosening the locking screw 2311, the axial position of the upper push plate 2312 can be adjusted, thereby changing the compression amount of the elastic element 233 and realizing the adjustment of the clamping force and the fit state.

[0036] Optionally, to limit the swing angle of the pressure plate 234 at the ball joint and improve the stability of the contact point under vertical hoisting conditions, the clamping module 23 further includes a limiting member 236. The limiting member 236 is disposed in an annular groove 237 opened at the bottom end of the extension block 211. A keyway 2371 extending axially is opened on the groove wall of the annular groove 237. A key 2361 that mates with the keyway 2371 is provided on the outer periphery of the limiting member 236 to limit the circumferential rotation of the limiting member 236 relative to the extension block 211 and ensure that the limiting direction is consistent. The limiting member 236 has a plurality of adjusting holes 2362 spaced axially. A corresponding connecting hole 2111 is opened on the extension block 211. The locking member 238 can pass through the connecting hole 2111 and any one of the adjusting holes 2362 in sequence to fix the limiting member 236 at different axial positions. By changing the axial installation position of the limiting member 236, the relative distance between the limiting member 236 and the pressure plate 234 can be changed, so that when the pressure plate 234 swings to a predetermined angle, it forms an abutment limit with the limiting member 236, thereby realizing the adjustable limiting of the swing angle of the pressure plate 234 in stages. When the limiting member 236 is set close to the pressure plate 234, the swing angle of the pressure plate 234 is less restricted, and the pressure plate 234 tends to be "approximately locked". When the limiting member 236 is far away from the pressure plate 234, the pressure plate 234 can obtain a larger adaptive swing angle. This structure can achieve controllable constraint on the swing range of the pressure plate without changing the main structure of the ball joint.

[0037] While the clamping component 2 presses down from above, the supporting component 1 supports the device from below, and the two together form an upper and lower clamping constraint. Figures 2 to 5 as well as Figure 7 As shown, the supporting component 1 includes a base support 11 and a traction module 12. The base support 11 is located below the arc-shaped saddle beam 21 and is used to support the equipment to be transported from below. In this embodiment, the base support 11 can be selected as a flexible supporting belt base support. The traction modules 12 are arranged in pairs at both ends of the base support 11 and are used to drive the base support 11 to generate a supporting displacement, so that the base support 11 and the clamping component 2 together form a clamping constraint on the equipment to be transported.

[0038] Each traction module 12 includes a pulley frame 121, a pulley 122, a line-laying mechanism 123, and a traction rope 124. The pulley frame 121 is fixedly connected to the connecting block 3252; the pulley 122 is rotatably connected to the pulley frame 121 via a pulley axle; the line-laying mechanism 123 is located below the pulley frame 121 and is fixedly mounted on the column 412; one end of the traction rope 124 is connected to the line-laying mechanism 123 and can be wound and unwound with the line-laying mechanism 123, and the other end is wound around the pulley 122 and connected to the base support 11.

[0039] During the clamping and releasing process, the pulley frame 121 moves in conjunction with the connecting block 3252, causing a change in the effective length of the traction rope 124. The wire release mechanism 123 synchronously retracts and releases the traction rope 124 to compensate for excessive tension or slack of the traction rope 124, thereby ensuring the continuity and controllability of the support action of the base support 11, and cooperating with the downward pressing action of the clamping component 2 to complete the clamping and positioning.

[0040] When using the prefabricated cabin gantry crane grabbing mechanism of the present invention, the supporting frame 4 is first connected to the hook of the prefabricated cabin gantry crane 5 through the lifting ring 43, so that the equipment to be transported is positioned between the arc-shaped saddle beam 21 and the base support 11 and is aligned. Before operation, the traction rope 124 is adjusted by the line release mechanism 123 to set the initial height of the base support 11, so that the base support 11 is quickly aligned with the lower surface of the equipment and forms a reliable support.

[0041] When the equipment is lifted, its own weight acts on the traction rope 124 via the base support 11, and is transmitted to the pulley frame 121 through the pulley 122, thereby driving the slider 323 connected to the connecting block 3252 to slide vertically along the guide post 324 within the guide seat 321. The friction pads on both sides of the sliding groove provide damping for the downward movement of the slider 323 to buffer the movement and suppress impact.

[0042] The downward displacement of slider 323 serves as the input displacement, which is transmitted to proportional link 313 via first link 311. Proportional link 313 uses fixed hole 3131 as its rotation reference and adjusts the output displacement by selecting different hinge holes 314 to change the position of the input point. This output displacement is then transmitted via second link 312, driving the arc-shaped saddle beam 21 to move downward, causing the clamping assembly 2 to approach the supporting end in a pre-set stroke ratio, thus achieving proportional linkage control of the clamping process.

[0043] During the above-mentioned linkage process, the synchronous movement of the pulley frame 121 with the slider 323 will cause the effective length of the traction rope 124 to change. The wire release mechanism 123 performs synchronous winding and unwinding compensation on the traction rope 124 to maintain the rope tension and rope length matching, and avoid the traction rope 124 from being too tight and causing jamming or too loose and causing rope stacking, thereby ensuring that the linkage clamping process is continuous, stable and controllable.

[0044] Therefore, by adjusting the proportional linkage 313 in stages, the downward movement of the arc-shaped saddle beam 21 can be set to be greater than that of the base support 11, so that the relative distance between the two gradually decreases according to the preset stroke ratio and achieves the upper and lower clamping and positioning of the equipment; by switching the hinge hole 314, the clamping stroke can be matched in stages without changing the linkage length to adapt to equipment of different sizes. After clamping, the clamping module 23 forms multi-point clamping on the curved surface of the equipment through elastic buffer and adaptive fit with the ball joint, and works with the flexible pad 235 to protect the surface, thereby maintaining clamping stability under transportation vibration conditions.

[0045] Example 2: like Figures 1 to 3 , Figure 7 as well as Figure 11 As shown, without changing the supporting component 1, clamping component 2, guiding adjustment component 3 and their linkage transmission relationship in Embodiment 1, this embodiment is used for transporting vertical equipment, and the vertical equipment is provided with flanges, reinforcing ribs or other load-bearing structures on both sides. During operation, the arc-shaped saddle beam 21 and its clamping module 23 are arranged at a predetermined height position of the equipment. The pressure plate 234, under the adaptive action of the ball joint connection, comes into contact with the outer edge, side or other load-bearing structure of the upper flange of the equipment and forms a clamping effect. At the same time, the bottom support 11 is set below the lower flange of the equipment and supports the lower surface of the lower flange, the step bearing surface or its adjacent bearing edge, so that the clamping component 2 and the supporting component 1 act on the upper and lower load-bearing structures of the equipment respectively and form upper and lower clamping constraints.

[0046] Optionally, the connecting plate 42 is configured as a detachable structure. The connecting plate 42 can be detachably connected to the crossbeam 411 via bolts, pins, or other detachable connection methods. When the equipment to be transported is vertical equipment, and its upper flanges, accessories, or load-bearing structures need to enter or approach the upper space of the load-bearing frame 4 during transport, the connecting plate 42 may obstruct or restrict the passage of the upper structure. Therefore, the connecting plate 42 can be removed or removed before operation to release upper clearance and create clearance space, thereby reducing the risk of the upper structure of the equipment being blocked, scratched, or jammed. After the connecting plate 42 is removed, the two inverted U-shaped gantry cranes 41 can be connected to the prefabricated cabin crane 5 respectively. It is preferred to adopt a double connection point arrangement with a balance beam to constrain the relative distance and attitude of the two inverted U-shaped gantry cranes 41 and balance the load, suppress relative sway and achieve synchronous transfer. Under the above connection arrangement, the clamping component 2 and the supporting component 1 can still maintain a synchronous linkage relationship under the symmetrical guidance of the guide adjustment component 3, and move closer together according to the preset stroke ratio to complete the clamping and positioning.

[0047] like Figure 11 and Figure 12As shown, to reduce the risk of excessive swaying, contact point drift, and slippage of the pressure plate 234 caused by lateral disturbances during vertical equipment transport, the limiting member 236 structure described in Embodiment 1 can be preferably adopted: by selecting different adjustment holes 2362 through the locking member 238, the limiting member 236 is installed in an axial position close to the pressure plate 234, thereby reducing the allowable sway angle of the pressure plate 234, making the pressing direction of the pressure plate 234 on the flange or other load-bearing structure more stable and the contact more reliable; when a certain degree of adaptability is required to accommodate flange processing errors or assembly deviations, the limiting member 236 can be adjusted to a position away from the pressure plate 234 to obtain a larger sway angle and maintain the fitting ability. Thus, under the condition of vertical equipment transport, it can ensure effective pressing of the load-bearing structure, while also taking into account the protection of the equipment surface and the adaptability to deviations.

[0048] like Figure 1 , Figure 4 , Figure 7 and Figure 10 As shown, optionally, to adapt to the differences in the dimensions and shapes of the load-bearing structures of different specifications of vertical equipment, the radius of curvature, axial length of the arc-shaped saddle beam 21, and the number and spacing of the clamping modules 23 can be selected or adjusted according to the load-bearing structures on both sides of the equipment, such as the outer diameter, thickness, or projection size range of the flange, so that the pressure plate 234 can form a stable fit with the load-bearing structure; at the same time, the support width, support length, and shape of the support surface in contact with the equipment of the base support 11 can be selected or adjusted according to the lower shape of the equipment and the projection size of the load-bearing structure, so as to achieve reliable clamping and transfer of vertical equipment with different load-bearing structures without changing the guide adjustment component 3 and its linkage transmission relationship.

[0049] The remaining structures, linkage principles, and rope path compensation methods in this embodiment are the same as in Embodiment 1, and will not be repeated here.

[0050] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
