A large storage tank hoisting connector

Abstract

This invention relates to the field of tank lifting technology and provides a large storage tank lifting connector, including a frame, a first clamping mechanism, a second clamping mechanism, and a lifting device. The first clamping mechanism clamps and fixes the wall panel, so that as the lifting device raises the lifting seat, it simultaneously moves the clamped wall panel upwards. Since the lifting seat and frame are elastically supported, the relative displacement of the lifting seat relative to the frame causes the second clamping mechanism to activate, reinforcing and fixing the second clamping mechanism during the lifting process. In this invention, the wall panel is clamped and fixed before the lifting device begins lifting; therefore, during lifting, the wall panel moves upwards accordingly, avoiding the problem in existing technologies where the clamping point of the limiting plate changes during the lifting process before the limiting plate has clamped the wall panel.

Description

Technical Field

[0001] This invention belongs to the field of tank hoisting technology, and particularly relates to a hoisting connector for large storage tanks. Background Technology

[0002] Currently, large-diameter non-standard circular tank wall panels are generally installed and welded in sections from bottom to top using the upright installation method, and the chain hoist inverted installation method is used for construction. When the upright installation method is used to install the wall panels in sections, the wall panels are lifted into place by a crane.

[0003] For example, the prior art document CN114291485A discloses an anti-detachment tank wall panel clamping device, which includes: a placement body, a support arm symmetrically arranged below the placement body, a clamping groove in the middle of the support arm, a limiting groove in the support arm, and the limiting groove and the clamping groove communicating through a first through groove; and a clamping assembly, which includes two clamping blocks symmetrically arranged in the support arm, the clamping blocks being embedded in the first through groove, a limiting plate on one side of the clamping block, the limiting plate being embedded in the limiting groove, and the limiting plate being connected to the side wall of the limiting groove through a first spring.

[0004] In the actual implementation of the above scheme, when pulling the handle, the support arm may also move upward simultaneously. In other words, before the limit plate clamps the wall panel, the clamping point of the limit plate on the wall panel will change during the hoisting process. This will require additional adjustments when the wall panel is moved to the designated position, reducing the practicality of the hoisting structure. Overall, additional wall panel adjustment work is required, making the operation cumbersome and the hoisting efficiency of the wall panel low. Summary of the Invention

[0005] The purpose of this invention is to provide a large storage tank hoisting connector, which aims to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A large storage tank hoisting connector includes a frame, a first clamping mechanism, a second clamping mechanism, and a lifting device. The frame includes a frame and a lifting seat. The lifting seat is elastically connected to the frame. The first clamping mechanism and the second clamping mechanism are both mounted on the lifting seat. The lifting device is connected to the lifting seat. The first clamping mechanism clamps and fixes the wall panel. As the lifting device lifts the lifting seat upward, it simultaneously moves the clamped and fixed wall panel upward. With the relative displacement of the lifting seat relative to the frame, the second clamping mechanism is activated to reinforce and fix the wall panel during the lifting process.

[0008] Furthermore, the lifting device includes a lifting base, on which a support wheel is rotatably mounted, and a hook is rotatably connected to the top of the lifting base for hanging on a crane; the lifting device also includes a steel rope, with both ends of the steel rope connected to two sets of connecting hooks, which are respectively fixedly installed at both ends of the lifting base; the middle section of the steel rope is wound around the support wheel.

[0009] Furthermore, the first clamping mechanism includes a support plate, which is fixedly mounted on the lifting seat. A servo motor is provided on the support plate, and the output shaft end of the servo motor is fixedly connected to the middle part of the drive rod. When the servo motor is started, the drive rod can rotate around the middle part. The first clamping mechanism also includes two sets of legs. The open inner wall of the legs is provided with guide grooves. The bottom horizontal side of the support plate is integrally formed and fixed with guide rails that are adapted to the guide grooves. The legs are slidably connected to the bottom of the support plate through the mutual cooperation of the guide rails and guide grooves. The first clamping mechanism also includes two sets of support legs. The bottom end of the support leg is integrally formed and fixedly connected to the corresponding support foot. The top end of the support leg is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to one end of the drive rod. Therefore, when the drive rod is rotated by the activated servo motor, the two sets of support feet can be pushed to move relative to each other under the linkage of the connecting rod and the support leg. The first clamping mechanism further includes two sets of first clamping blocks, which are respectively fixedly connected to two sets of corresponding legs; specifically, the top surface of the first clamping block is fixedly connected to the connecting leg, and the top end of the connecting leg is fixedly connected to the leg.

[0010] Furthermore, the second clamping mechanism includes a rotating toothed sleeve with an internal thread groove. The rotating toothed sleeve is threaded onto the lead screw via the internal thread groove. A second clamping block is fixedly provided at the extended end of the lead screw. A receiving groove for accommodating the second clamping block is provided on the first clamping block. The end of the rotating toothed sleeve is rotatably connected to the first clamping block.

[0011] Furthermore, a lifting rack is fixedly installed on the lifting seat. The lifting rack meshes with the rotating sleeve. When the lifting device pulls the lifting seat upward, it will drive the lifting rack to move upward, thereby driving the rotating sleeve to rotate. The rotating sleeve will push the second clamping block to form a feed movement to fasten the wall panel.

[0012] Furthermore, the lifting rack is provided with supporting protrusions, and the outer ring of the rotating sleeve has supporting grooves, with the supporting protrusions meshing with the supporting grooves.

[0013] Furthermore, the axial length of the rotating gear sleeve is greater than the width of the lifting rack, so that when the first clamping block and the rotating gear sleeve undergo lateral displacement, the meshing between the rotating gear sleeve and the lifting rack will not disengage.

[0014] Furthermore, a support guide rod is fixedly installed on the inner wall of the frame, and a guide groove is provided on the first clamping block to cooperate with the support guide rod. The support guide rod slides against the guide groove to guide the lateral movement of the first clamping block and the rotating gear sleeve.

[0015] Furthermore, a support back plate is fixedly installed on the inner wall of the frame, which is used to support the bottom edge of the lifting seat; the frame and the lifting seat are connected by a support spring.

[0016] Compared with the prior art, in the specific implementation of the large storage tank hoisting connector provided by the present invention, the first clamping mechanism is used to clamp and fix the wall panel, so that when the lifting device lifts the lifting seat upward, it will simultaneously drive the clamped and fixed wall panel to move upward. Since the lifting seat and the frame are elastically supported, as the lifting seat moves relative to the frame, the second clamping mechanism is activated to reinforce and fix the second clamping mechanism during the lifting process of the lifting device. The first clamping mechanism provided by the embodiment of the present invention drives the corresponding two sets of first clamping blocks to move closer together by bringing the two sets of support legs closer together, thereby achieving clamping and fixing of the wall panel. Then, the lifting device is used for the lifting process. The wall panel is clamped and fixed before the lifting device lifts. Therefore, during the lifting process, the wall panel will also move upward, avoiding the problem in the prior art where the clamping point of the limiting plate on the wall panel changes during the lifting process before the limiting plate clamps the wall panel.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0022] like Figure 1 As shown, in one embodiment of the present invention, a large storage tank hoisting connector is provided, which is used to hoist the wall panel 600.

[0023] The large storage tank hoisting connector includes a frame, a first clamping mechanism 400, a second clamping mechanism 500, and a lifting device. The frame includes a frame 100 and a lifting seat 200. The lifting seat 200 is elastically connected to the frame 100. The first clamping mechanism 400 and the second clamping mechanism 500 are both installed on the lifting seat 200. The lifting device is connected to the lifting seat 200. In a specific implementation, the first clamping mechanism 400 clamps and fixes the wall panel 600, so that when the lifting device lifts the lifting seat 200 upward, it will simultaneously drive the clamped wall panel 600 upward. Since the lifting seat 200 and the frame 100 are elastically supported, as the lifting seat 200 moves relative to the frame 100, the second clamping mechanism 500 moves to reinforce and fix the wall panel 600 during the lifting process.

[0024] As a preferred option, such as Figure 1 and Figure 8 As shown, in this embodiment of the invention, the lifting device includes a lifting base 300, on which a support wheel 303 is rotatably mounted, and a hook 301 is rotatably connected to the top of the lifting base 300 for mounting on a crane; the lifting device also includes a steel rope 302, with both ends of the steel rope 302 connected to two sets of connecting hooks 201, which are respectively fixedly installed at both ends of the lifting base 200; the middle section of the steel rope 302 is wound around the support wheel 303.

[0025] Please continue reading. Figures 1-3 In this embodiment of the invention, the first clamping mechanism 400 includes a support plate 401, which is fixedly mounted on the lifting seat 200. A servo motor 403 is provided on the support plate 401. The output shaft end of the servo motor 403 is fixedly connected to the middle part of the drive rod 408. When the servo motor 403 is started, the drive rod 408 can rotate around its middle part.

[0026] Furthermore, the first clamping mechanism 400 also includes two sets of support legs 404. The open inner wall of the support legs 404 is provided with guide grooves 405. The bottom horizontal side of the support plate 401 is integrally formed and fixedly provided with a guide rail 402 that is adapted to the guide grooves 405. The support legs 404 are slidably connected to the bottom of the support plate 401 through the mutual cooperation of the guide rails 402 and the guide grooves 405.

[0027] Furthermore, in this embodiment of the invention, the first clamping mechanism 400 further includes two sets of support legs 406, the bottom end of which is integrally formed and fixedly connected to the corresponding support foot 404; the top end of which is hinged to one end of the connecting rod 407, and the other end of the connecting rod 407 is hinged to one end of the driving rod 408. Therefore, when the driving rod 408 is rotated by the activated servo motor 403, the two sets of support feet 404 can be pushed to move relative to each other under the linkage of the connecting rod 407 and the support legs 406; specifically, to Figure 2 For example, when the drive rod 408 rotates counterclockwise, the two sets of support legs 404 move closer to each other; when the drive rod 408 rotates clockwise, the two sets of support legs 404 move further apart from each other.

[0028] Furthermore, such as Figures 2-4 As shown, in this embodiment of the invention, the first clamping mechanism 400 further includes two sets of first clamping blocks 501, which are respectively fixedly connected to two sets of corresponding legs 404; specifically, the top surface of the first clamping block 501 is fixedly connected to the connecting leg 4041, and the top end of the connecting leg 4041 is fixedly connected to the leg 404.

[0029] Based on the above detailed description of the first clamping mechanism 400, it can be seen that the first clamping mechanism 400 provided in this embodiment of the invention clamps the wall panel 600 by bringing the two sets of legs 404 closer together, thereby driving the corresponding two sets of first clamping blocks 501 closer together. Then, the wall panel 600 is clamped and fixed by the lifting equipment. Before the lifting equipment lifts the wall panel 600, the wall panel 600 is clamped and fixed. Therefore, during the lifting process, the wall panel 600 will also move upward. This avoids the problem in the prior art where the clamping point of the limiting plate on the wall panel 600 changes during the lifting process before the limiting plate clamps the wall panel 600.

[0030] Furthermore, such as Figures 4-6 As shown, in this embodiment of the invention, the second clamping mechanism 500 includes a rotating toothed sleeve 506, which is provided with an internal threaded groove 5061. The rotating toothed sleeve 506 is threadedly connected to the lead screw 505 through the internal threaded groove 5061. A second clamping block 504 is fixedly provided at the extended end of the lead screw 505. A receiving groove 503 for accommodating the second clamping block 504 is provided on the first clamping block 501. The end of the rotating toothed sleeve 506 is rotatably connected to the first clamping block 501.

[0031] In a specific implementation of the second clamping mechanism 500 provided by the present invention, the rotating toothed sleeve 506 is rotated. Since the lead screw 505 and the rotating toothed sleeve 506 are connected by a thread, when the rotating toothed sleeve 506 rotates, it can push the lead screw 505 and the second clamping block 504 to generate displacement, thereby causing the second clamping block 504 to extend out of the receiving groove 503, so that the second clamping block 504 can further fasten and fix the wall plate 600.

[0032] Please continue reading. Figure 1 , Figure 4 and Figure 7 In this embodiment of the invention, a lifting rack 202 is fixedly provided on the lifting seat 200. The lifting rack 202 meshes with the rotating sleeve 506. When the lifting device lifts the lifting seat 200 upward, it will drive the lifting rack 202 to move upward, thereby driving the rotating sleeve 506 to rotate. The rotating sleeve 506 will push the second clamping block 504 to form a feed movement to fasten the wall panel 600.

[0033] As a preferred option, such as Figure 7 As shown, in this embodiment of the invention, the lifting rack 202 is provided with a supporting protrusion 2021, and the outer ring of the rotating sleeve 506 has a supporting groove 5062, and the supporting protrusion 2021 meshes with the supporting groove 5062.

[0034] As a preferred option, such as Figure 1 and Figure 4 As shown, in this embodiment of the invention, the axial length of the rotating toothed sleeve 506 is greater than the width of the lifting rack 202, so that when the first clamping block 501 and the rotating toothed sleeve 506 undergo lateral displacement, the meshing between the rotating toothed sleeve 506 and the lifting rack 202 will not disengage.

[0035] Please continue reading. Figure 1 and Figure 4 In this embodiment of the invention, a support guide rod 102 is also fixedly provided on the inner wall of the frame 100. The first clamping block 501 is provided with a guide groove 502 that cooperates with the support guide rod 102. The support guide rod 102 slides against the guide groove 502 to guide the lateral movement of the first clamping block 501 and the rotating toothed sleeve 506.

[0036] Please continue reading. Figure 1 In this embodiment of the invention, a support back plate 101 is also fixedly provided on the inner wall of the frame 100. The support back plate 101 is used to support the bottom edge of the lifting seat 200. The frame 100 and the lifting seat 200 are connected by a support spring 103.
