Description

Technical Field

[0001] This invention relates to the field of corrugated plate construction technology, and in particular to an auxiliary hanger for hoisting large-radius steel corrugated plates. Background Technology

[0002] Metal corrugated steel plate structures are widely used in underground structures of railway, highway, municipal, and mining projects, as well as in the reinforcement of old bridges and culverts, highway tunnels, seepage wells, and coal mine roadways. Corrugated steel plates are a new type of building structure. They have good ductility, strong resistance to deformation, and are quick and easy to install, saving construction time. They also have advantages such as low cost and environmental friendliness, making them more advantageous than traditional reinforced concrete structures. They are lightweight and quick to construct, and are superior to traditional structures in terms of both cost and construction time.

[0003] For example, the utility model patent application with authorization announcement number CN214784177U and authorization announcement date of November 19, 2021, entitled "A Steel Corrugated Plate Culvert Structure," includes a culvert foundation, culvert sidewalls, culvert top, and reinforcing components. The culvert foundation is a reinforced concrete structure. The culvert sidewalls include a left sidewall and a right sidewall arranged parallel to each other, which are fixedly set above the culvert foundation. The structure of the culvert sidewalls consists of two parallel steel corrugated plates with a steel reinforcement cage placed between them. The two steel corrugated plates and the steel reinforcement cage are fastened together by tie bolts through the sidewalls. The space between the two steel corrugated plates is filled with poured concrete. The culvert top is a steel corrugated plate arch, with the left and right ends of the culvert top fixedly set on the top of the left and right sidewalls, respectively. A reinforcing component is set at intervals in the culvert, and the reinforcing component includes sidewall steel and foundation steel.

[0004] In existing technology, when installing corrugated steel sheets, cranes are often used to lift and install them. A lifting diagram is attached. Figure 1 As shown, a crane lifts the corrugated sheet and moves it to a suitable position using a wire rope. However, in railway, highway and other engineering projects, the corrugated sheets used are long and thin, and sometimes they are assembled from multiple sections of corrugated sheets, resulting in a large overall weight. Directly lifting the corrugated sheet with a crane and wire rope can easily cause large irreversible deformation, affecting the installation quality of the corrugated sheet. Summary of the Invention

Detailed Implementation

[0036] 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.

[0037] like Figure 1-15 As shown, the present invention provides an auxiliary hoisting frame for large-radius corrugated steel plates, including a frame body 2. The frame body 2 is provided with a suspension mounting component 20 for fixing the suspension rope 11. The frame body 2 is equipped with a top support component 21 for supporting the top of the corrugated steel plate 10 and an end support component 22 for supporting both sides of the corrugated steel plate 10. The top support component 21 and the end support component 22 include an inner support plate 23 and an outer pressure plate 26. The inner support plate 23 is connected to the frame body 2 through a telescopic connector 7. The outer pressure plate 26 can be installed on the outside of the corrugated steel plate 10 and is fixedly connected to the inner support plate 23.

[0038] Specifically, the suspended large-radius corrugated steel plate 10 can be a single piece or multiple pieces connected together. For ease of description, the corrugated steel plate 10 referred to in this embodiment is the large-radius corrugated steel plate 10. The frame 2 is used to support the corrugated steel plate 10 for suspension. The shape and size of the frame 2 correspond to the corrugated steel plate 10. In this embodiment, the frame 2 is suitable for corrugated steel plates 10 with an arc-shaped structure. The shape of the frame 2 can be triangular, trapezoidal, etc. At least four suspension mounting parts 20 that can be connected to the suspension rope 11 are provided on the frame 2. That is, at least two suspension mounting parts 20 are provided on each of the opposite sides of the frame 2, and the distance between the suspension mounting parts 20 on both sides is greater than the width of the corrugated steel plate 10. This avoids the suspension rope 11 from pressing or colliding with the corrugated steel plate 10 during the suspension process.

[0039] In this embodiment, a top support assembly 21 and an end support assembly 22 are provided on the frame 2. The top support assembly 21 supports the top of the corrugated steel plate 10, which has an arc-shaped structure. The end support assemblies 22 are located on opposite sides of the bottom of the frame 2. The two end support assemblies 22 can support the two sides of the corrugated steel plate 10. The line connecting the top support assembly 21 and the two end support assemblies 22 forms an isosceles triangle. The support points between the top support assembly 21 and the end support assembly 22 and the corrugated steel plate 10 can be one, two, or more. In this way, the top support assembly 21 and the end support assembly 22 can achieve multi-point support when suspending the corrugated steel plate 10.

[0040] In this embodiment, both the top support assembly 21 and the end support assembly 22 include a telescopic connector 7, an inner support plate 23, and an outer pressure plate 26. The inner support plate 23 and the outer pressure plate 26 are correspondingly arranged so that they can be installed on the inner and outer sides of the corrugated steel plate 10, respectively. The lengths of the inner support plate 23 and the outer pressure plate 26 are both greater than the width of the corrugated steel plate 10. A fixing structure is provided at the protruding portion 25 of the inner support plate 23 and the outer pressure plate 26 relative to the corrugated steel plate 10. The fixing structure can fix the inner support plate 23 and the outer pressure plate 26, thereby making the corrugated steel plate 10 more stable. The corrugated plate 10 is fixed between the inner support plate 23 and the outer pressure plate 26. The positions of the inner pressure plate and the outer pressure plate 26 can be adjusted by the telescopic connector 7, so that the inner tooth plate can be adjusted to a suitable position to support the top and sides of the steel corrugated plate 10. The telescopic connectors 7 of the top support assembly 21 and the end support assembly 22 can be the same or different. For example, the telescopic connector 7 of the top support assembly 21 is a hydraulic jack, and the telescopic connector 7 of the end support assembly 22 is a hydraulic telescopic rod. At the same time, the telescopic connector 7 can also be other mechanisms.

[0041] In this embodiment, when suspending the corrugated steel plate 10 using a hoisting auxiliary hanger, the process includes the following steps:

[0042] The first step is to adjust the telescopic connector 7 according to the size of the corrugated steel plate 10 so that the inner support plate 23 of the top support assembly 21 can fit and support the inner wall of the corrugated steel plate 10, and fix the outer pressure plate 26 on the inner support plate 23 to fix the top of the corrugated steel plate 10.

[0043] The second step is to adjust the position of the inner support plate 23 of the two side support components 641 by means of the telescopic connector 7, so that the inner support plate 23 fits and supports against the corrugated steel plate 10, and the outer pressure plate 26 is fixedly installed on the inner support plate 23 to fix the two sides of the corrugated steel plate 10.

[0044] The third step is to install the suspension rope 11 on the suspension mounting component 20 and suspend the corrugated steel plate 10 by using the crane 1 or other suspension device.

[0045] The large-radius corrugated steel plate 10 hoisting auxiliary hanger provided by the present invention has a suspension mounting component 20 on the frame body 2 for fixing the suspension rope 11. The frame body 2 is equipped with a top support component 21 for supporting the top of the corrugated steel plate 10 and an end support component 22 for supporting the two sides of the corrugated steel plate 10. During the suspension process, the suspension rope 11 suspends the frame body 2, the top support component 21 on the frame body 2 supports the top of the corrugated steel plate 10, and the two end support components 22 fix and support the sides of the corrugated steel plate 10. The top support component 21 and the end support components 22 achieve multi-point support for the corrugated steel plate 10, so that the corrugated steel plate 10 is subjected to uniform force and avoids large irreversible deformation of the corrugated steel plate 10.

[0046] In the embodiments provided by the present invention, preferably, the suspension mounting component 20 includes suspension seats 201 disposed on opposite sides of the frame 2. The suspension seats 201 are provided with a fixing mounting part that can be fixedly installed with the suspension rope 11. That is, along the width direction of the corrugated steel plate 10, suspension seats 201 are provided on both sides of the frame 2, and there are at least two suspension seats 201 on each side of the frame 2. The distance between the suspension seats 201 on both sides is greater than the width of the corrugated steel plate 10, so as to avoid the suspension rope 11 from contacting the corrugated steel plate 10 during the suspension process. The fixing mounting part can be a fixing mounting hole. During use, the suspension rope 11 is fixedly installed in the fixing mounting hole. At the same time, in order to improve the stability of the suspension process, suspension seats 201 can also be set at different heights of the frame 2, so that the suspension rope 11 can be fixed at different heights of the frame 2.

[0047] In the embodiments provided by the present invention, the lengths of the inner support plate 23 and the outer pressure plate 26 are greater than the width of the corrugated steel plate 10. Both the inner support plate 23 and the outer pressure plate 26 are provided with intersecting corrugated support structures 24 that correspond to the waveform of the corrugated steel plate 10. The corrugated support structures are located on the side of the inner support plate 23 and the outer pressure plate 26 corresponding to the corrugated steel plate 10. The corrugated support structures include sequentially connected protrusions 240 and recesses 241. When the inner support plate 23 and the outer pressure plate 26 are installed, the protrusions 240 and recesses 241 of the inner support plate 23 and the corrugated steel plate 10 are aligned. The protrusions and grooves on the inner wall of plate 10 are sequentially fitted together, and the protrusions 240 and recesses 241 of the outer pressure plate 26 are sequentially fitted together with the protrusions and grooves on the outer wall of the corrugated steel plate 10. The advantage of this arrangement is that the inner support plate 23 and the outer pressure plate 26 cannot move along the width direction of the corrugated steel plate 10, and the telescopic connector 7 can provide a radial support force along the corrugated steel plate 10. Thus, after the inner support plate 23 and the outer pressure plate 26 are fixed, they cannot move along the circumference of the corrugated steel plate 10, thereby improving the fixing strength between the inner support plate 23 and the outer pressure plate 26 and the corrugated steel plate 10.

[0048] The inner support plate 23 and the outer pressure plate 26 are provided with matching fixing parts 250 on both sides of their length direction. The length of the corrugated support structure 24 of the inner support plate 23 and the outer pressure plate 26 is consistent with the width of the corrugated steel plate 10. Both ends of the inner support plate 23 and the outer pressure plate 26 at the length direction of the corrugated support structure form protrusions 25 that extend relative to the corrugated steel plate 10. The fixing part 250 can be a fixing screw hole provided on the protrusion 25. The number of fixing screw holes can be set as needed. In use, the fixing bolts can be rotated and fixed in the fixing screw holes on the inner support plate 23 and the outer pressure plate 26 in sequence to fix the outer pressure plate 26, the corrugated steel plate 10 and the inner support plate 23.

[0049] In a preferred embodiment of the present invention, the top support assembly 21 further includes an arc-shaped support seat 210. The arc-shaped support seat 210 is provided with at least two sets of inner support plates 23 and outer pressure plates 26. The side wall of the arc-shaped support seat 210 corresponding to the inner side wall of the corrugated steel plate 10 is an arc-shaped wall, and the arc-shaped wall is consistent with the curvature of the top inner wall of the corrugated steel plate 10. The inner support plates 23 are fixedly installed on the arc-shaped wall. The arc-shaped support seat 210 is connected to the telescopic connector 7. In this way, the position of the arc-shaped support seat 210 can be adjusted by the telescopic connector 7, so that each inner support plate 23 on the arc-shaped wall is synchronously attached and fixed to the inner wall of the corrugated steel plate 10.

[0050] In the embodiments provided by the present invention, the frame 2 further includes an I-shaped hanger formed by connecting a bottom crossbeam 27, a top crossbeam 28, and vertical rods 29. The length of the top crossbeam 28 is less than the length of the bottom crossbeam 27. Both the bottom crossbeam 27 and the top crossbeam 28 are horizontally arranged. The top crossbeam 28 is fixedly connected to the bottom crossbeam 27 through vertical rods 29. There can be two or more vertical rods 29. Telescopic connectors 7 are provided on opposite sides of the bottom crossbeam 27. The inner support plate 23 is located at the end of the telescopic connector 7 away from the bottom crossbeam 27. The arc-shaped support seat 210 is fixed directly above the top crossbeam 28 through the telescopic connectors 7. Thus, in use, by adjusting the three telescopic connectors 7, the inner support plates 23 can be driven respectively so that each inner support plate 23 can fit against the inner wall of the corrugated steel plate 10. Then, the outer pressure plate 26 is fixedly installed on the inner support plate 23 to fix the corrugated steel plate 10.

[0051] In the preferred embodiment provided by the present invention, the frame 2 further includes a side support beam 3, the upper end and the lower end of which are connected to the top crossbeam 28 and the bottom crossbeam 27, respectively; there are two side support beams 3, which are fixedly installed at opposite ends of the top crossbeam 28 and the bottom crossbeam 27, so that the top crossbeam 28, the bottom crossbeam 27 and the two side support beams 3 are connected to form a trapezoidal hanger.

[0052] In the embodiments provided by the present invention, a side support mechanism 4 is further included, which is disposed on the side support beam 3 and is used to support the side of the corrugated steel plate 10. Each side support beam 3 is provided with a side support mechanism 4. The side support mechanism 4 can support the inner wall of the corrugated steel plate 10 between the top support component 21 and the end support component 22, thus forming multiple more support points along the circumference of the corrugated steel plate 10, so that the corrugated steel plate 10 can maintain its original curvature during hoisting and transportation and will not undergo irreversible deformation.

[0053] The side support mechanism 4 includes an arc-shaped side plate 40 and a side support assembly 641 disposed on the arc-shaped side plate 40. At least two side support assemblies 641 are disposed on each arc-shaped side plate 40. The arc shape of the arc-shaped side plate 40 corresponds to the arc of the corrugated steel plate 10. The side support assembly 641 is disposed radially along the arc-shaped side plate 40. One end of the side support assembly 641 is fixedly connected to the arc-shaped side plate 40, and the other end of the side support assembly 641 can support the inner wall of the corrugated steel plate 10.

[0054] The side support assembly 641 includes a support rod 42 that is vertically fixedly connected to the arc-shaped side plate 40. A strip support member 43 is provided at the end of the support rod 42 away from the arc-shaped side plate 40. The strip support member 43 is provided with a corrugated support structure. The corrugated support structure on the strip support member 43 is correspondingly arranged with the steel corrugated plate 10. In use, the protrusion 240 and the recess 241 of the strip support member 43 are sequentially fitted with the protrusions and grooves on the inner wall of the steel corrugated plate 10 to form a support.

[0055] When suspending the corrugated steel sheet 10 using a hoisting auxiliary frame, for ease of installation and disassembly, the side support components 641 are in a pressing contact with the inner wall of the corrugated steel sheet 10. That is, the side support components 641 are not fixed to the corrugated steel sheet 10, but a suitable pressing force must be maintained at all times so that each side support component 641 can provide support for the corrugated steel sheet 10. Therefore, in another embodiment of the present invention, a drive mechanism 5 for driving the side support components 641 is also provided on the frame 2. The drive mechanism 5 is connected to the suspension rope 11. The suspension rope 11 is then used to drive the side support beam 3 for adjustment and support. For ease of description, the continuous lifting process is divided into two processes: In the first lifting process, the suspension rope 11 drives the drive mechanism 5, thereby driving the arc-shaped side plate 40 and the side support assembly 641 to move to both sides until each side support assembly 641 presses against the inner wall of the corrugated steel plate 10. During this process, the corrugated steel plate 10 does not leave the ground. In the second lifting process, the suspension rope 11 applies force to the drive mechanism 5 and the frame 2 simultaneously to suspend the steel corrugated steel plate 10, thereby lifting it up.

[0056] In another embodiment of the present invention, preferably, the upper end of the side support beam 3 is rotatably connected to the top crossbeam 28 via a rotating shaft, and arc-shaped portions 270 are provided on both opposite sides of the bottom crossbeam 27. Arc-shaped grooves 271 are provided in the arc-shaped portions 270. The bottom of the two side support beams 3 is rotatably restricted by rotation limiting members and the arc-shaped grooves 271. The drive mechanism 5 is slidably connected to the vertical rod 29. During the first lifting process, the drive mechanism 5 is driven to move upward along the vertical rod 29 by the suspension rope 11. When the drive mechanism 5 is driven to move upward, the side support beam 3 is driven to rotate to both sides, so that the side support assembly 641 rotates with the side support beam 3 and presses against the inner wall of the corrugated steel plate 10.

[0057] In another embodiment of the present invention, preferably, the driving mechanism 5 includes a motion seat 50, which has a through hole for the vertical rod 29 to pass through. When the motion seat 50 is driven, it will move up and down along the vertical rod 29. A pressing driving member 51 is provided at both ends of the motion seat 50 along its length. A sliding limiting part 30 is provided on the opposite sidewalls of the two side support beams 3. The sliding limiting part 30 can be a sliding groove. The pressing driving member 51 is slidably connected in the sliding limiting part 30. Suspension seats 201 are provided on both sides of the motion seat 50. The suspension seats 201 have fixing holes for installing the suspension rope 11. Specifically, along the width direction of the corrugated steel plate 10, suspension seats 201 are provided on both sides of the frame 2, and there are at least two suspension seats 201 on each side of the motion seat 50, located between the two suspension seats 201. The spacing is greater than the width of the corrugated steel plate 10. A suspension limiting seat 280 is provided on the top crossbeam 28. The suspension limiting seat 280 is provided with a limiting hole. The limiting hole only restricts the suspension rope 11 to improve the stability during the suspension process. It is not directly fixed to the suspension rope 11. During installation, the lower end of the suspension rope 11 passes through the limiting hole and is fixedly connected to the suspension seat 201 on the motion seat 50. Thus, during the lifting process, the suspension rope 11 is installed on the suspension seats 201 on both sides of the motion seat 50. The upper ends of the suspension rope 11 are connected to the hook of the crane 1. During the first lifting process, the suspension rope 11 applies force to the motion seat 50. The motion seat 50 moves upward along the vertical bar 29. The pressure driving member 51 on the motion seat 50 presses against the side support beams 3, causing the side support beams 3 to rotate to both sides.

[0058] In another embodiment of the present invention, preferably, a vertical guide rod 52 is provided on the bottom crossbeam 27, and a top force-bearing plate 53 is provided on the top of the vertical guide rod 52. The motion seat 50 is integrally provided with an arc-shaped side 500, and a guide hole for the vertical guide rod 52 to pass through is provided on the arc-shaped side 500. The top force-bearing plate 53 is configured such that at the end of the first lifting process, the arc-shaped side 500 directly abuts against the top force-bearing plate 53. The advantage of this configuration is that, firstly, during the first lifting process, the vertical guide rod 52 supports the movement of the motion seat 50. Firstly, the moving seat 50 moves up and down along the vertical rod 29, acting as a guide. Secondly, during the second lifting process, the moving seat 50 directly applies force to the load-bearing plate, which is fixedly connected to the frame 2, thus enabling the direct application of suspension force to the frame 2. Thirdly, during the second lifting process, the position of the moving seat 50 along the vertical rod 29 remains unchanged, and the moving seat 50 always maintains pressure against each side support component, so that each side support component 641 maintains appropriate support force on the inner wall of the corrugated steel plate 10, preventing the corrugated steel plate 10 from deforming during the lifting process.

[0059] In another embodiment of the present invention, preferably, a first spring member 54 is also included. Each vertical rod 29 is fitted with a first spring member 54. The upper end of the first spring member 54 is fixedly connected to the top crossbeam 28. In the initial state, the lower end of the first spring member 54 may or may not be in contact with the moving seat 50. Thus, during the first lifting process, when the moving seat 50 moves upward along the vertical rod 29, it will press against the first spring member 54, so that the first spring member 54 is in a compressed state. The first spring member 54 plays the role of spring buffer for the moving seat 50. At the same time, after the corrugated steel plate 10 is suspended to a suitable position and installed, after the upward tension of the crane 1 and the suspension rope 11 on the moving seat 50 disappears, under the action of the first spring member 54, the moving seat 50 can move downward along the vertical rod 29. The moving seat 50 causes the side support beam 3 to rotate in the opposite direction by pressing the drive member 51, so that each side support assembly 641 is separated from the inner wall of the corrugated steel plate 10, which facilitates the disassembly of the frame 2 and the corrugated steel plate 10.

[0060] In another embodiment of the present invention, optionally, the force-bearing plate is adjustablely mounted on the vertical guide rod 52. For example, a threaded part is provided at the top of the vertical guide rod 52, and the force-bearing plate is adjustablely mounted on the vertical guide rod 52 by means of a nut. In this way, by adjusting the position of the force-bearing plate, the movement stroke of the moving seat 50 during the first lifting process can be adjusted, so that the rotation angle of each side support beam 3 and the pressure of each side support assembly 641 against the inner wall of the corrugated steel plate 10 can be adjusted, thereby meeting different requirements for the suspension process of the corrugated steel plate 10.

[0061] In actual use, there may be inconsistencies in the pressure exerted between the side support assembly 641 and the corrugated steel plate 10, and some side support assemblies 641 may be in contact with the corrugated steel plate 10 while others may be separated. Therefore, in another embodiment of the present invention, the side support assembly 641 further includes a self-adjusting support member 44. There are two self-adjusting support members 44, which are arranged on both sides of the strip support member 43. The self-adjusting support member is connected to the support rod 42 through the elastic component 45. During the first lifting process, the side support assembly 641 is driven to have two states: a first pressing state and a second pressing state. When the top support assembly 21 and the end support assembly 22 are fixed to the corrugated steel plate 10, the side support assembly 641 has no pressure exerted on the inner wall of the corrugated steel plate 10. Subsequently, the suspension rope 11 applies force to the moving seat 50, causing the moving seat 50 to move upward along the vertical rod 29. During the movement, the side support beam 3 is driven to rotate. When the side support assembly 641 rotates with the side support beam 3 to a certain position, it enters the first pressing state. At this time, the self-adjusting support member 44 presses against the inner wall of the corrugated steel plate 10, while the strip support member 43 does not contact the inner wall of the corrugated steel plate 10. Subsequently, as the side support continues to rotate, the pressing force between the self-adjusting support member 44 and the corrugated steel plate 10 increases. During this process, the self-adjusting support member is driven to rotate away from the strip support member 43 and presses against the elastic component 45. When the self-adjusting support member rotates to the maximum angle, the self-adjusting support member and the strip support member simultaneously press against the corrugated steel plate 10. At this time, the side support assembly 641 is in the second pressing state. The self-adjusting support member remains at this maximum angle and will not continue to rotate. When the pressing force on the self-adjusting support member decreases, the self-adjusting support member will rotate in the opposite direction, causing the side support assembly 641 to automatically switch back to the first pressing state.

[0062] By setting the self-adjusting support 44, its function during use is as follows: First, regardless of whether the side support assembly 641 is in the first pressing state or the second pressing state, the side support assembly 641 can provide support for the corrugated steel plate 10; Second, the side support assembly 641 can be adjusted according to the pressure. When the pressing force between the side support assembly 641 and the corrugated steel plate 10 increases, the rotation angle of the support is automatically adjusted to increase until it switches to the second pressing state. When the pressing force between the side support assembly 641 and the corrugated steel plate 10 decreases, the rotation angle of the support is automatically adjusted to decrease.

[0063] In another embodiment of the present invention, preferably, the elastic component 45 includes an annular motion plate 450, a second spring member 451, and an annular fixing plate 452. The annular fixing plate 452 is fixedly mounted on the support rod 42, and the annular motion plate 450 is movably fitted onto the support rod 42. The annular motion plate 450 is driven to reciprocate along the axial direction of the support rod 42. The second spring member 451 is sleeved on the support rod 42, and its two ends are respectively connected to the annular fixing plate 452 and the annular motion plate 450. Two first hinge seats 4520 are provided on the annular fixing plate 452, and two second hinge seats 4500 are provided on the annular motion plate 450. A first rotating rod 453 is rotatably mounted on the first hinge seat 4520, and a second rotating rod 453 is provided on the second hinge seat 4500. The upper ends of the two rotating rods 454, the first rotating rod 453, and the second rotating rod 454 are both fixed to the self-adjusting support member 44. When the self-adjusting support member 44 is driven to rotate away from the strip support member 43, the first rotating rod 453 rotates while pressing against the annular motion plate 450, causing the annular motion plate 450 to move downward along the support rod 42 and stretch the second spring member 451. A torsion spring is provided between the bottom of the first rotating rod 453 and the first hinge seat 4520. When the self-adjusting support member 44 rotates away from the strip support member 43, the torsion spring is rotated and stores force. When the pressure on the self-adjusting support member 44 decreases or disappears, under the action of the second spring member 451 and the torsion spring, the self-adjusting support member 44 rotates in the opposite direction until it returns to its initial state.

[0064] In another embodiment of the present invention, optionally, the self-adjusting support 44 includes a U-shaped frame 440, a roller mounting shaft 441 is provided inside the U-shaped frame 440, and a plurality of rollers 442 are provided on the roller mounting shaft 441. The spacing between the rollers 442 corresponds to the waveform of the corrugated steel plate 10. Thus, when the self-adjusting support 44 contacts the corrugated steel plate 10, each roller 442 corresponds to a recess in the corrugated steel plate 10. When the first rotating rod 453 and the second rotating rod 454 rotate, the rollers 442 roll along the recesses of the corrugated steel plate 10. This reduces the friction between the self-adjusting support 44 and the corrugated steel plate 10. At the same time, the rollers 442 and the corrugated steel plate 10 are adaptively matched, and the rollers 442 are restricted along the width direction of the corrugated steel plate 10 to prevent the self-adjusting support 44 from moving during rotation.

[0065] In another embodiment of the present invention, further, in order to enable the elastic support force between the side support components 641 on the same side support beam 3 to be mutually adjustable, the arc-shaped side plate 40 includes multiple segments that are hinged to each other. An arc-shaped beam 8 is fixedly arranged directly above the top crossbeam 28. At this time, the suspension limiting seat 280 is arranged on the arc-shaped beam 8. The uppermost segment of the arc-shaped side plate 40 is hinged to the arc-shaped beam 8. Each segment of the arc-shaped side plate 40 is provided with a side support component 641. The support rod 42 of the side support component 641 is fixedly installed on each segment of the arc-shaped side plate 40. An X-shaped support frame 60 is arranged between the arc-shaped side plate 40 and the side support beam 3. The X-shaped support frame 60 includes a first support shaft 61 and a second support shaft 62 that are rotatably connected. A first top sliding seat 610 and a first bottom sliding seat 611 are respectively provided at the upper and lower ends of the support shaft 61. A second top sliding seat 620 and a second bottom sliding seat 621 are respectively provided at the upper and lower ends of the second support shaft 62. A sliding mounting rod 31 is fixedly provided on the side of the side support beam 3 near the arc-shaped side plate 40. The first bottom sliding seat 611 and the second bottom sliding seat 621 are slidably connected between the sliding mounting rod 31, and a third spring member 32 is provided on the sliding mounting rod 31. No third spring member 32 is provided between the first bottom sliding seat 611 and the second bottom sliding seat 621 of the same X-shaped support frame 60, but a third spring member 32 is provided between the first bottom sliding seat 611 and the second bottom sliding seat 621 of adjacent X-shaped support frames 60. A third spring member 32 (the two ends of the third spring member 32 are respectively fixed on the first bottom sliding seat 611 and the second bottom sliding seat 621 of the adjacent X-shaped support frame 60) is provided with an arc-shaped groove 271 on the side of each arc-shaped side plate 40 near the side support beam 3. The X-shaped support frame 60 and each arc-shaped side plate 40 are arranged alternately, that is, the first top sliding seat 610 of one X-shaped support frame 60 is slidably connected in the arc-shaped groove 271 of one arc-shaped side plate 40, and the second top sliding seat 620 of the X-shaped support frame 60 is slidably connected in the arc-shaped groove 271 of another arc-shaped side plate 40 adjacent to the first arc-shaped side plate 40. The advantage of this arrangement is that when a certain side support component 641 and the corrugated steel plate 10 are in contact, the pressure difference between them is reduced. When the pressure is large, the side support component 641 exerts greater pressure on the opposite arc-shaped side plate 40. This arc-shaped side plate 40 simultaneously drives the two X-shaped support frames 60, causing them to adjust synchronously. The adjustment of the two X-shaped support frames 60 allows for simultaneous adjustment of the angles of the three arc-shaped side plates 40. Furthermore, since a third spring 32 is provided between the first bottom sliding seat 611 and the second bottom sliding seat 621 of two adjacent X-shaped support frames 60, the pressure exerted on the X-shaped support frame 60 can be transmitted to the other X-shaped support frames 60 through the third spring 32. This allows the arc-shaped side plates 40 to adjust their angles synchronously until the pressure exerted on each side support component 641 is basically the same or within the allowable control range.

[0066] The process by which the X-shaped support frame 60 is pressed down to transmit pressure, thereby driving other X-shaped support frames 60, is as follows: Two X-shaped support frames 60 connected to the same arc-shaped side plate 40 (referred to as the pressing arc-shaped side plate 40) are called the first X-shaped support frame 60 and the second X-shaped support frame 60. The first support shaft 61 of the first X-shaped support frame 60 and the second support shaft 62 of the second X-shaped support frame 60 are slidably connected to the pressing arc-shaped side plate 40. When the pressing force of the pressing X-shaped support frame 60 is large, it will press down on the first support shaft 61 of the first X-shaped support frame 60 and the second support shaft 62 of the second X-shaped support frame 60, thereby causing the first X-shaped support frame 60 and the second X-shaped support frame 60 to be adjusted by the pressing force. When the frame 60 is adjusted, the first bottom sliding seat 621 of the first X-shaped support frame 60 and the second bottom sliding seat 621 of the second X-shaped support frame 60 slide along the sliding mounting rod 31, thereby pressing against the third spring member 32. In this way, the first X-shaped support frame 60 and the second X-shaped support frame 60 drive the X-shaped support frame 60 on their sides through the third spring member 32, so that the X-shaped support frame 60 on their sides is also driven and adjusted. Thus, each X-shaped support frame 60 is driven and adjusted, so that each section of the arc-shaped side plate 40 can be adjusted to match the arc-shaped corrugated steel plate 10, and the pressure of each side support component 641 on the corrugated steel plate 10 can also be adjusted and controlled within a suitable range, ensuring that the corrugated steel plate 10 will not undergo irreversible deformation during the hoisting process.

[0067] 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.
