[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This solution is applied to the hoisting of pipelines during municipal pipeline installation.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a hoisting device for municipal pipeline construction, including a support plate 1 and a controller. A box 2 is fixed at the top of the support plate 1, and a lifting ring 3 is fixed at the top of the box 2. When using the device, the lifting ring 3 is connected to the hook of a crane or other lifting mechanism to lift the device.

[0018] Pull ropes 4 are movably arranged on both sides of the support plate 1. In order to increase the strength of the pull ropes 4, in this scheme, the pull ropes 4 are preferably steel wire ropes. A collar 6 with an inner diameter larger than the outer diameter of the pipe 9 is fixed at one end of the pull rope 4, and a limiting member 7 for limiting the top of the pipe body of the pipe 9 is provided at the top of the inner ring of the collar 6.

[0019] like Figure 1 , Figure 3 and Figure 4 As shown, the limiting component 7 includes a hydraulic cylinder 701 fixed to the inner wall of the top of the collar 6. The hydraulic cylinder 701 is perpendicular to the ground, and the center of the collar 6 is located on the extension line of the central axis of the hydraulic cylinder 701 rod. A U-shaped plate 702 is fixed to the end of the extension end of the hydraulic cylinder 701. A through groove is opened at the bottom of both sides of the U-shaped plate 702, and a connecting shaft is fixed in the through groove. A pressure roller 703 is movably connected to the shaft of the connecting shaft. To increase the friction between the pressure roller 703 and the pipe 9 and prevent longitudinal displacement of the pipe 9 during hoisting, the pressure roller 703 in this solution is preferably a rubber roller. Figure 4 As shown, during hoisting, the pipe 9 is located inside the collar 6, and the bottom surface of the pipe 9 is in contact with the inner wall of the top of the collar 6. At this time, two pressure rollers 703 are symmetrically distributed on both sides of the top of the pipe 9. The connection between the two pressure rollers 703 and the bottom surface of the pipe 9 and the inner wall of the top of the collar 6 forms a triangular mechanism, thereby achieving a stable connection of pipes 9 with different diameters.

[0020] A drive unit 5 is provided on the opposite side of the two pull ropes 4, and the pull ropes 4 are wound up by the drive unit 5.

[0021] Specifically, such as Figure 2As shown, the drive unit 5 includes two take-up shafts 501 movably disposed at the bottom of the housing 2. One side of the pull rope 4 is wound around the roller of the take-up shaft 501. Gears 502 meshing with each other are fixed on the shafts of the two take-up shafts 501 extending out of the housing 2. A side mounting box 505 is provided on one side of the housing 2. A worm gear 503 is fixed on one of the take-up shafts 501. A worm 504 is movably connected to the bottom of the side mounting box 505, and the worm 504 meshes with the worm gear 503. A motor 506 is fixed to the side of the 05, and the output end of the motor 506 is fixed to the end of the worm 504. After the motor 506 is started, the two winding shafts 501 can rotate in different directions to wind up the ropes 4 on both sides, thereby lifting the pipe 9. In addition, it is understood that since the worm 504 and the worm wheel 503 are meshed, they have a self-locking function, which can effectively prevent the disorderly rotation of the two winding shafts 501 and improve the safety of the lifting device.

[0022] To reduce wear on the top wall of the wire hole on the support plate 1 on the pull rope 4, right-angle guide tubes 8 are fixed on both sides of the top of the support plate 1, and the pull rope 4 moves through the right-angle guide tubes 8.

[0023] As a supplement to this solution, during use, the lifting ring 3 is connected to the hook of a crane or other lifting mechanism to lift the device and move it directly above the pipe 9 to be lifted. The controller controls the motor 506 to start, and the two winding shafts 501 rotate in opposite directions to unwind the pull rope 4. When the pull rope 4 is unwound to a certain amount, the workers pull the collar 6 to both sides and put the collar 6 on the pipe 9. The controller controls the hydraulic cylinder 701 to extend. When the hydraulic cylinder 701 extends, it drives the pressure roller 703 to move downward until the pressure roller 703 presses against the top of the pipe 9, thus fixing the pipe 9. At this time, the controller controls the motor 506 to rotate in the opposite direction, and the winding shaft 501 winds up the pull rope 4, thereby realizing the lifting of the pipe 9.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
