Description

Technical Field

[0001] The present invention relates to the technical field of equipment connection construction, in particular to a large-scale corrugated pipe joint docking device. Background Art

[0002] Currently, the main approach to repairing old, damaged sewage pipes that were previously buried is to replace them with durable, corrosion-resistant corrugated pipes. Overall, after the replacement, the urban sewage system operates smoothly and produces less odor. However, during the pipeline laying process, a large number of pipe joints are required. For the docking of small-diameter corrugated pipe joints, construction workers currently use auxiliary snap-on connection devices to perform the docking. However, when docking large-diameter corrugated pipe joints, the heavy weight of the pipes makes it inconvenient for workers to operate. Furthermore, external lifting equipment is required to move and adjust the materials, which is time-consuming and labor-intensive. Furthermore, large corrugated pipes require tightening the joints after docking, requiring precise positioning of the corrugated pipe joints. However, existing external lifting methods make it difficult to accurately adjust and position the joints at both ends of large corrugated pipes, affecting the subsequent process of connecting the corrugated pipes. Traditional corrugated pipe joint docking equipment is unable to handle such situations, which in turn affects the construction of the corrugated pipe joints and ultimately has a certain impact on the construction progress. Therefore, we propose a large-scale corrugated pipe joint docking device to address the above-mentioned problems. Summary of the Invention

DETAILED DESCRIPTION

[0030] Example 1:

[0031] like Figures 1 to 10 In the invention, a large-scale bellows joint docking device includes two large bellows 1. One large bellows 1 is provided with a lifting device 2 on both sides, and the other large bellows 1 is provided with a docking device 3 on both sides. The two lifting devices 2 and the two docking devices 3 are connected by a bending clamp 4. The bending clamp 4 rests on the outer wall of the large bellows 1. The lifting device 2 and the docking device 3 on the same side are connected by a telescopic hydraulic jack 15. With this structure, the device has a simple structure, is easy to operate, and has a wide range of applications. Compared with traditional bellows joint connection devices, the device is suitable for the docking construction of bellows joints with different pipe diameters, and at the same time, it saves operators time and effort during construction.

[0032] The present invention has been optimized in structure to a certain extent. It adopts the connection between the bending clamp 4 and the two lifting devices 2 or the docking device 3, which can be effectively applied to the connection of large corrugated pipes 1 with various diameters. Compared with the traditional corrugated pipe joint auxiliary device, it has the advantage of a wide range of applications. The bending clamp 4 can be opened and closed. When opened, the bending clamp 4 is relatively straight and can be inserted from the gap at the bottom of the large corrugated pipe 1. After the bending clamp 4 is inserted through the large corrugated pipe 1, the two first arc-shaped holders 401 of the bending clamp 4 are lifted, so that the bending clamp 4 can be fitted on the outer wall of the large corrugated pipe 1. The installation and disassembly are quick and easy, so that the bending clamp 4 can be quickly and conveniently placed against the large corrugated pipe 1.

[0033] During the construction of bellows joints, the present invention utilizes a telescopic hydraulic jack 15 to ensure smooth dragging and installation of the large bellows 1 joint, saving time and effort for construction workers. Furthermore, the device is recyclable. More importantly, the device is extremely convenient to assemble, debug, and disassemble. Therefore, the device offers significant practical value compared to conventional bellows joint auxiliary connections.

[0034] The two lifting devices 2 of the present invention can be relatively close to or relative to the large bellows 1, and the adjusting mechanism 5 on the lifting device 2 can move horizontally and vertically to adjust the flat docking position of the large bellows 1 on the lifting device 2. The adjusting mechanism 5 on the docking device 3 can move and adjust horizontally and vertically to adjust the flat docking position of the large bellows 1 on the docking device 3, and drive the telescopic hydraulic jack 15 to make the docking device 3 close to the lifting device 2, so that the two large bellows 1 are closed, so that the two large bellows 1 can be docked accurately, which is convenient for the subsequent large bellows 1 joint welding or other additional pressure device connection. It will not have a certain impact on the construction progress of the project, and improve construction efficiency. At the same time, there is no need to use external lifting equipment to move and adjust the materials, which ensures that the personnel are easy to operate during the joint connection process, saves time and effort, further optimizes the connection steps, and has the advantage of low construction safety risk.

[0035] In the preferred embodiment, the lifting device 2 includes an adjustment mechanism 5, a connector 14, and a trolley 17, and the docking device 3 includes an adjustment mechanism 5, a second connector 16, and a trolley 17. With this structure, the two lifting devices 2 drive the adjustment mechanism 5 on the lifting devices 2 to move the lifting plates 13 on the two lifting devices 2, thereby moving the corresponding bending clamps 4 of the lifting devices 2 on the horizontal plane, thereby accurately adjusting the position of the lifting devices 2 relative to the large corrugated pipe 1.

[0036] The two docking devices 3 are also precisely adjusted to their horizontal positions on the corresponding large bellows 1 by the adjustment mechanism 5 on the docking device 3. The telescopic hydraulic jack 15 is driven to retract, so that the docking device 3 moves closer to the lifting device 2, thereby moving the two large bellows 1 closer together to achieve precise adjustment when docking the two large bellows 1.

[0037] In the preferred embodiment, the adjustment mechanism 5 includes a slideway 6, on which is mounted a sliding screw seat 9, which is mounted a receiving plate 10, and on which is mounted a lifting plate 13 that rises and falls. With this structure, the motor 7 is driven to rotate the screw 8, causing the screw seat 9 to slide relative to the slideway 6. The motors 7 of the two adjustment mechanisms 5 corresponding to the same large bellows 1 are synchronized to move the lifting plate 13 away from or closer to the large bellows 1.

A guide rod 12 is provided on the receiving plate 10, and the guide rod 12 abuts against the through-hole 1301. With this structure, the hydraulic cylinders 11 on the two adjustment mechanisms 5 corresponding to the same large bellows 1 are synchronized and driven to vertically raise and lower the lifting plate 13 to adjust the height position of the large bellows 1.

[0040] In the preferred embodiment, connector 14 includes a turntable 1401, with sleeves 1402 and shafts 1403 at either end. One end of a telescopic hydraulic jack 15 rests against sleeve 1402, while shaft 1403 is rotatably connected to trolley 17. With this structure, one end of telescopic hydraulic jack 15 is rotatably connected to lifting device 2 via connector 14, while the other end of telescopic hydraulic jack 15 is rotatably connected to docking device 3 via second connector 16, thereby closing the two large bellows 1. The use of telescopic hydraulic jack 15 ensures smooth dragging and undocking of the large bellows 1 joint, saving time and effort for construction workers.

[0041] In the preferred embodiment, the second connecting member 16 has the same structure as the connecting member 14 and is rotatably connected to the trolley 17 on the docking device 3. A bolt hole 1601 is provided on the sleeve of the second connecting member 16. A connecting hole 1501 is provided at one end of the telescopic hydraulic jack 15, and a bolt passes through the bolt hole 1601 and the connecting hole 1501. With this structure, the telescopic hydraulic jack 15 is connected to the second connecting member 16 via bolts.

The two first curved pieces 401 are respectively connected to different lifting plates 13. This structure allows the bending clamp 4 to be opened and closed. When opened, the bending clamp 4 is relatively straight and can be inserted through the gap at the bottom of the large corrugated tube 1. After the bending clamp 4 has been inserted through the large corrugated tube 1, the two first curved pieces 401 of the bending clamp 4 are lifted, allowing the bending clamp 4 to be placed against the outer wall of the large corrugated tube 1. This allows for quick and easy installation and removal, allowing the bending clamp 4 to be quickly and conveniently placed against the large corrugated tube 1.

[0043] In the preferred embodiment, a connecting plate 4011 is provided at one end of the first curved holding member 401. The two connecting plates 4011 are respectively connected to the lifting plates 13 on the two lifting devices 2 or the two docking devices 3. The other end of the first curved holding member 401 is provided with an arcuate groove 4012, with hinge holes 4013 on either side of the arcuate groove 4012. The second curved holding member 402 is provided with curved plates 4021 at both ends. These curved plates 4021 are provided with rotating posts 4022, which abut against the rotating posts 4022, which in turn abut against the hinge holes 4013. With this structure, the connecting plate 4011 is connected to the lifting plate 13 via bolts. After the bent clamp 4 passes through the bottom of the large corrugated tube 1, the first curved holding member 401 is lifted and closed relative to the second curved holding member 402, so that the closed bent clamp 4 can abut against the outer wall of the large corrugated tube 1.

A hydraulic pump is provided on one side of the lifting device 2, and the hydraulic pump is connected to the telescopic hydraulic jack 15 through a pipeline.

Opening two bending clamps 4, which are relatively straight and can be inserted through the gap at the bottom of the large bellows 1. After the bending clamps 4 have been inserted through the large bellows 1, lifting the two first arc-shaped holding pieces 401 of the bending clamps 4 allows the bending clamps 4 to fit against the outer wall of the large bellows 1.

[0047] Multiple motors 7 and hydraulic cylinders 11 are driven to adjust the position of the lifting plate 13. The two ends of the two bent clamps 4 are bolted to the lifting plate 13 on the lifting device 2 or the docking device 3.
