Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a lifting device for pipe cleaning. Background Technology

[0002] In industrial production, the cleaning of tubular materials is a crucial step in ensuring product quality and smooth production processes. Currently, the transfer and cleaning of tubular materials typically involves using lifting equipment in conjunction with clamping modules to hoist and transfer the materials for subsequent cleaning. However, the existing lifting equipment and clamping modules have several shortcomings in practical use.

[0003] On the one hand, when dealing with long tubular materials, existing clamping modules are prone to uneven heights at both ends during lifting due to manufacturing errors and uneven weight distribution of the material itself, causing the material to tilt during lifting. For example, Chinese Patent (202310786914.4) discloses a double-arm lifting device with a self-propelled lifting mechanism, including a tower and a slewing mechanism. Two horizontal arms are symmetrically arranged on the tower, and the inner ends of the horizontal arms are rotatably connected to the tower. The tower has two winches at the top of the slewing section. Two winches correspond to two boom arms, and the winches are connected to the corresponding boom arms by steel wire ropes. A guide rail is provided along the length of each boom arm, and a traveling mechanism is mounted on the guide rail for guidance. A lifting mechanism is also mounted on the traveling mechanism. A generator is mounted on each boom arm, and the generator is electrically connected to the slewing mechanism, winches, traveling mechanism, and lifting mechanism. Remote control modules are installed on the generator, slewing mechanism, winches, traveling mechanism, and lifting mechanism, and these remote control modules are connected to a remote control system.

[0004] However, in actual use, material skewing may occur. This skewing not only affects the safety of material transfer and increases the risk of material falling, but may also cause insufficient or uneven cleaning during the cleaning operation, seriously affecting the cleaning quality and efficiency. On the other hand, existing lifting equipment lacks effective adjustment devices and cannot make precise fine adjustments to both ends of the clamp module, making it difficult to meet the lifting needs of tubular materials of different lengths and weights, which greatly limits the application range and effectiveness of the lifting equipment. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a lifting device for pipe cleaning. The device utilizes the cooperation of the lifting equipment and the clamp module to transfer tubular materials and complete the cleaning operation. The adjusting device allows for fine-tuning of both ends of the clamp module, ensuring that both ends remain horizontal and preventing skewing when lifting materials of considerable length.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lifting device for pipe cleaning, comprising a lifting module and a clamping module. The lifting module includes a truss and a traveling beam. A lifting motor is mounted on the truss. A pulley block is mounted on the upper part of the clamping module. A sling is mounted between the pulley block and the lifting motor. A rope end fixer connected to the sling is mounted on one side of the lifting motor. An adjustment device is mounted above the rope end fixer.

[0009] The pull rod is provided with a fall arrestor block located below the adjusting nut, and the upper part of the anti-rotation bracket is provided with a limit seat corresponding to the position of the fall arrestor block.

[0010] The limiting seat has a spherical storage cavity in the middle, and the anti-fall block has a sliding hemisphere at the bottom.

[0011] The truss is equipped with drive motors at both ends, and the upper part of the traveling beam is equipped with guide rails located below the truss.

[0012] The clamp module includes a mounting frame, within which a crossbeam is provided. Two symmetrically distributed hooks are provided at the lower part of the crossbeam, and a drive assembly for rotating the hooks is provided at the upper part of the crossbeam.

[0013] The drive assembly includes a rotating shaft, the lower end of which is detachably connected to a hook, and a drive arm on the upper part. A push rod connected to the drive arm is provided above the crossbeam, and a hydraulic cylinder is provided at the end of the push rod.

[0014] The push rod is provided with a connecting column, and the drive arm is provided with a clearance groove corresponding to the position of the connecting column.

[0022] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] like Figure 1-2As shown, the lifting equipment for pipe cleaning in this embodiment includes a lifting module and a clamping module. The lifting module includes a truss 1 and a traveling beam 2. Drive motors 17 are installed at both ends of the truss 1. The drive motors 17 drive the truss 1 to move laterally along the guide rail 18. A lifting motor 3 is installed on the truss 1. The lifting motor 3 drives the drum to wind up and unwind the sling 6 through a reducer. After the sling 6 passes through the pulley block 4 of the clamping module, its end is fixed to one side of the lifting motor 3 by a rope end fixing device 7. The pulley block 4 adopts a double pulley design to reduce the wear of the sling 6. An anti-rotation bracket 8 is installed above the rope end fixing device 7. A load-bearing plate 9 is provided in the middle of the anti-rotation bracket 8. A tie rod 10 is welded at the center of the load-bearing plate 9. The tie rod 10 passes through the through hole at the top of the anti-rotation bracket 8. A connecting seat 11 connected to the rope end fixing device 7 is provided at the bottom of the tie rod 10. The height of the load-bearing plate 9 is adjusted by rotating the adjusting nut 12, thereby fine-tuning the height of the sling 6, and thus achieving the purpose of adjusting the two ends of the lifting module to maintain balance.

[0024] like Figure 3-4 As shown, a fall arrestor block 13 is installed on the pull rod 10. A sliding hemisphere 16 is provided at the lower part of the fall arrestor block 13. A limit seat 14 is provided at the top of the anti-rotation bracket 8. A spherical storage cavity 15 is machined at the center of the limit seat 14. The design of the spherical storage cavity 15 and the sliding hemisphere 16 can ensure that the sliding hemisphere 16 can rotate at any angle to realize the deflection angle rotation of the wire rope.

[0025] like Figure 5 As shown, the mounting frame 19 of the clamp module is a rectangular steel structure with a fixed crossbeam 20 inside. Two hooks 21 are symmetrically installed below the crossbeam 20. A rotating shaft 22 is installed inside the crossbeam 20. The upper end of the rotating shaft 22 extends above the crossbeam 20 and connects to the drive arm 23. A hydraulic cylinder 25 is horizontally fixed at the top of the mounting frame 19. The piston rod of the hydraulic cylinder 25 is connected to a push rod 24. The end of the push rod 24 slides with the clearance groove 27 of the drive arm 23 through a connecting column 26. The clearance groove 27 is designed as an arc-shaped long groove structure, which allows the connecting column 26 to adaptively offset its angle when the push rod 24 moves, avoiding motion interference. The mounting frame 19 is also equipped with a fall arrestor extending to the top of the truss 1 to prevent the clamp module from detaching from the lifting module during operation, ensuring the safety of the lifting operation.

[0026] When the hydraulic cylinder 25 extends or retracts, the push rod 24 pushes the drive arm 23 to rotate around the rotating shaft 22, thereby controlling the rotation of the hook 21. The forward and reverse rotation of the hook 21 realizes the clamping and releasing of tubular materials. Every two hooks 21 form a complete clamping group. Multiple clamping groups are provided on the mounting frame 19, which are evenly distributed along its length. Adjacent clamping groups are linked by a transmission rod. After being driven by the same hydraulic cylinder 25, multiple clamping groups can operate synchronously. This allows for multi-point support of materials with large lengths, reducing the gravity on each clamping group.

[0027] When the equipment is running, the lifting motor 3 releases the sling 6 to lower the clamp module to the pipe position. The operator rotates the adjusting nut 12 to adjust the height of the sling 6 so that the two ends of the clamp module are in a balanced state. Then the hydraulic cylinder 25 retracts, and the push rod 24 pushes the drive arm 23 outward, causing the hook 21 to rotate 90 degrees clockwise and clamp the pipe. The drive motor 17 drives the truss 1 to move along the guide rail 18 to the cleaning station. After cleaning is completed, the hydraulic cylinder 25 resets, causing the hook 21 to rotate 90 degrees counterclockwise and release the pipe. The lifting motor 3 then retracts the sling 6 to reset.
