Description

Technical Field

[0001] This utility model belongs to the field of pipeline construction technology, and in particular relates to a device for aligning transverse pipelines connected to inspection wells. Background Technology

[0002] In the construction of urban underground drainage systems, municipal pipe networks, and other infrastructure, the connection between inspection wells and horizontal pipes is a crucial link. The rational and efficient completion of the connection between pipes is of great significance for ensuring the normal operation of the entire pipe network system, improving drainage efficiency, and reducing later maintenance costs.

[0003] In pipeline connection construction, due to the large weight of the pipeline itself and the lack of effective auxiliary devices, construction personnel often need to spend a lot of manpower and time to adjust the position of the pipeline to ensure that the pipeline interface can be accurately aligned. It is difficult to guarantee the horizontal alignment accuracy of the pipeline during the operation, which can easily lead to gaps at the interface, affecting the sealing and overall performance of the pipeline. Therefore, it is necessary to provide a horizontal pipeline alignment device for manhole connection, which uses a method of quickly deploying hand-operated hoists and related connection structures to pull and push adjacent pipe sections, thereby achieving precise and tight alignment.

[0021] In the following description, an embodiment of the present invention for aligning a transverse pipe connecting a manhole will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates an embodiment of a manhole connection horizontal pipe alignment device, comprising bases 2 located on the front and rear sides of a first pipe section 1. The two bases 2 are mirror images of each other. A hand-operated hoist 3 is fixedly installed on the side of each base 2 away from the first pipe section 1. Fixing components 4 are provided at the top and bottom of the two bases 2, each including a fixing seat 41 and a fixing plate 44 respectively fixedly connected to the top and bottom of the bases 2. A chain 42 is rotatably connected to the inner cavity of the fixing seat 41, and a threaded post 43 is rotatably connected to the end of the chain 42 away from the fixing seat 41. A threaded sleeve 45 is rotatably connected to the inner cavity of the fixing plate 44, and the threaded sleeve 45 is threaded onto the surface of the threaded post 43. The chain 42 wraps around the surface of the first pipe section 1, and a hexagonal threaded sleeve is welded to the surface of the threaded sleeve 45. Through the arrangement of the fixing components 4, the threaded post 43 and the threaded sleeve 45 work together to align the chain 42. 2 serves to tighten and fix the base. With the cooperation of the base 2 and the chain 42, the base 2 and the hand chain hoist 3 can be stably and quickly installed on the surface of the first pipe section 1. The second pipe section 5 is set on the right side of the first pipe section 1. The blocking frame 6 is set on the right side of the second pipe section 5. The front and rear sides of the top of the blocking frame 6 are welded with the hanging rod 10. The hanging rod 10 is hung on the right side of the top of the second pipe section 5. The anti-slip pad 11 is glued to the side of the base 2 near the first pipe section 1. The anti-slip pad 11 is a rubber pad. With the setting of the hanging rod 10, the blocking frame 6 can be pre-hung on the right side of the top of the second pipe section 5, so as to facilitate the user to connect and wire the traction rope 9 and the hook 7. The front and rear ends of the right side of the blocking frame 6 are opened with two connecting holes 8. The inner cavity of the connecting hole 8 is bolted with the traction rope 9. The lifting end of the hand chain hoist 3 is fixedly connected with the hook 7, and the hook 7 is sleeved on the surface of the traction rope 9.

[0023] Working Principle: In use, the user hoists the first pipe section 1 and the second pipe section 5 to the designated installation positions. Then, the user places the chain 42 onto the surface of the first pipe section 1, and inserts the threaded post 43 into the inner cavity of the threaded sleeve 45. Using a wrench, the threaded sleeve 45 is rotated. Through the interaction of the threads on the surface of the threaded post 43 and the threads on the inner wall of the threaded sleeve 45, the threaded post 43 enters the inner cavity of the threaded sleeve 45. The pulling action of the threaded post 43 tightens and secures the chain 42, thereby stably installing the two bases 2 on the front and rear sides of the first pipe section 1. Finally, the blocking bracket 6 is attached to the right side of the second pipe section 5. This allows the boom 10 to be hung on the right side of the top of the second pipe section 5, temporarily fixing the blocking frame 6. Then, the user places the hook 7 on the surface of the traction rope 9 and rotates the operating lever of the hand chain hoist 3 to tighten the hook 7, thereby pulling the traction rope 9. Under the linkage of the traction rope 9 and the blocking frame 6, the second pipe section 5 is pulled to the left, allowing the left end of the second pipe section 5 to be pushed into the inner cavity of the first pipe section 1 for alignment. In actual use, the user can change the length of the traction rope 9 to push the subsequently installed pipe section, thus avoiding the user from frequently disassembling and assembling the base 2 and the hand chain hoist 3.

[0024] In summary: This inspection well is connected to a horizontal pipe alignment device. The two bases 2 are fixedly installed by the fixing component 4. Then, with the cooperation of the hand chain hoist 3, the traction rope 9 and the blocking frame 6, the first pipe section 1 and the second pipe section 5 can be connected. Then, with the cooperation of the hand chain hoist 3, the traction rope 9 and the blocking frame 6, the second pipe section 5 can be pulled in, thus achieving the purpose of easy horizontal alignment and quick and labor-saving disassembly and assembly.
