[0002] Municipal underground pipelines are a vital component of urban infrastructure, acting like the city's lifeblood to support its daily operations. These pipelines are diverse, including water supply pipes, drainage pipes, and gas pipelines, each serving a different function. Laid intricately underground, they form a vast network, ensuring the city's smooth operation and the convenience of residents' lives. Therefore, the construction and management of municipal underground pipelines are crucial for urban development.

[0003] When laying underground pipelines, it is usually necessary to transport the pipelines to the installation point, then disassemble the pipelines from the transport equipment, and finally use hoisting equipment to fix the pipelines and move them to the laying site. The pipeline transfer operation during laying is quite cumbersome and requires the use of various equipment, making the laying process quite challenging. To address these issues, a laying device for municipal underground pipeline construction is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is as follows: the transfer operation of the pipeline during laying is relatively complicated and requires the use of a variety of equipment, making the laying threshold high.

[0005] The objective of this utility model can be achieved through the following technical solutions:

One end of the rotating rod passes through the upright plate and is fixedly connected with a crank.

[0008] The rotating rod has winding wheels fixedly installed on both sides of its outer wall. Each winding wheel has a lifting rope wound around its outer side. One end of the lifting rope extends to the bottom of the winding wheel, and a hook is fixedly connected to the end of the lifting rope away from the winding wheel.

[0009] The limiting frame sidewall and the end near each upright plate are provided with internal threaded holes, and each internal threaded hole is threaded with a bolt.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, a laying device for municipal underground pipeline construction includes an adjusting mechanism 1, with a lifting mechanism 2 located in the middle of the adjusting mechanism 1. The adjusting mechanism 1 includes a limiting frame 101, with upright plates 107 fixedly installed on both sides of the top of the limiting frame 101. A rotating rod 108 is rotatably connected between the upper ends of the two upright plates 107. One end of the rotating rod 108 extends through the upright plate 107 and is fixedly connected to a crank 110. A winding wheel 109 is fixedly installed on both sides of the outer wall of the rotating rod 108. A lifting rope 111 is wound around the outer side of each winding wheel 109. One end of the lifting rope 111 extends below the winding wheel 109, and a hook 112 is fixedly connected to the end of the lifting rope 111 furthest from the winding wheel 109. An internally threaded hole 104 is provided on the side wall of the limiting frame 101 near each upright plate 107. A bolt 105 is threaded into the interior of each internally threaded hole 104. Figure 1 , Figure 3 , Figure 5 As shown, after the bolt 105 is tightened in the internal threaded hole 104, the end of the bolt 105 passes through the limit frame 101 and is inserted into the lower end of the lifting frame 201 to prevent the lifting frame 201 from falling.

[0028] The lifting mechanism 2 includes two lifting frames 201. The lower ends of the outer walls of the two lifting frames 201 are in movable contact with the inner sides of the limiting frame 101. The lower ends of the outer walls of each lifting frame 201 are also inserted into the ends of bolts 105. A connecting rod 202 is movably installed between the upper ends of the two lifting frames 201. Both ends of the connecting rod 202 extend out of the lifting frame 201, and both ends of the outer wall of the connecting rod 202 are threaded. Nuts 203 are also threaded onto both ends of the outer wall of the connecting rod 202, and the surfaces of the two nuts 203 abut against the surfaces of the lifting frames 201. Figure 1 , Figure 4 As shown, an opening is provided at the lower end of the surface of the upright plate 107 near the nut 203 and the insert rod 202, so that the insert rod 202 can be separated from the lifting frame 201 after the nut 203 is loosened.

[0029] Both lifting frames 201 are fixedly equipped with lifting lugs 204 on their tops. The upper end of the outer wall of each lifting lug 204 is connected to a hook 112. Base plates 102 are fixedly connected to both sides of the bottom surface of the limiting frame 101, and casters 103 are rotatably connected to the bottom of each base plate 102. A push rod 106 is also fixedly connected to one side of the outer wall of the limiting frame 101, with the top of the push rod 106 extending above the limiting frame 101. The adjusting mechanism 1 also includes support plates 113, of which two are provided. A limiting groove 114 is formed in the middle of the inner wall of the support plate 113. A magnetic suction element 115 is fixedly connected to one end of the inner wall of the limiting groove 114. The outer surface of the support plate 113 and the side near the magnetic suction element 115 are sloped. The inner side of the limiting groove 114 is slidably connected to the outer wall of the limiting frame 101, and the outer surface of the magnetic suction element 115 is also magnetically connected to the limiting frame 101. Figure 5 As shown, the limiting frame 101 is made of iron. When the magnetic component 115 approaches the limiting frame 101, it is attracted and positioned, so that the two support plates 113 remain in contact.

[0030] The working principle of this utility model:

[0031] When using the device, first loosen and remove the nuts on both sides of the insertion rod 202, then pass the insertion rod 202 through the lower end of the vertical plate 107 and take it out. Then, move the pipe to the top plane of the support plate 113 through the side slope of the support plate 113. After that, fix the insertion rod 202 again, install and tighten the nuts 203 at both ends of the insertion rod 202. The nuts 203 abut against the side of the lifting frame 201, thereby preventing the insertion rod 202 from moving relative to the lifting frame 201.

[0032] Secondly, by using the push rod 106 and the universal wheel 103, the entire device is moved to the top of the pipeline laying point. The support plate 113 is pushed away from the limit frame 101, so that the two support plates 113 are separated and the support plates 113 no longer support the pipeline above. The pipe is then supported by the insertion rod 202. Then, the bolt 105 is loosened and removed, and the end of the bolt 105 is separated from the lifting frame 201. Then, the crank 110 is rotated to drive the rotating rod 108 to rotate. At the same time, the winding wheels 109 on both sides of the rotating rod 108 release the hoisting rope 111, and then the entire lifting mechanism 2 moves down. The insertion rod 202 drives the entire pipeline to fall to the underground installation point. After the pipeline is supported from the bottom, the nut 203 is removed again according to the above operation. The insertion rod 202 is passed through the lower end of the upright plate 107 and taken out. The crank 110 is rotated in the opposite direction, and the winding wheel 109 takes in the hoisting rope 111. The lifting mechanism 2 is then moved up and reset through the hook 112.

[0033] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
