[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] Reference Figure 1-4 The utility model embodiment of a pipe lifting device for laying a municipal water supply and drainage pipe network includes: a balancing base 1, a load box 3 and a lifting beam 2 are fixedly connected to the upper surface of the balancing base 1, the load box 3 and the lifting beam 2 are relatively distributed on the left and right, and all auxiliary equipment required for lifting work are arranged inside the balancing base 1 and the lifting beam 2. The front and rear surfaces of the load box 3 are fixedly connected with reinforced legs 14. When the device is used, the reinforced legs 14 are in close contact with the ground. The reinforced legs 14 are composed of a stretching rod 16 and a prefabricated plate 17. The load box 3 cooperates with the reinforced legs 14 to improve the stability of the lifting device when in use. The front and rear surfaces of the balancing base 1 are fixedly connected with a storage sleeve 13. When the device is not in use, the reinforced legs 14 are located inside the storage sleeve 13, and the storage sleeve 13 is convenient for storing the reinforced legs 14.

[0024] One end of the lifting beam 2 away from the balancing base 1 is fixedly connected to two steel cables 4, and one end of the steel cable 4 away from the lifting beam 2 is fixedly connected to a cross mounting frame 5. The surface of the cross mounting frame 5 is fixedly connected to a reinforcement shell 10. The connection node between the steel cable 4 and the cross mounting frame 5 is located inside the reinforcement shell 10. The existence of the reinforcement shell 10 prevents the connection node between the steel cable 4 and the cross mounting frame 5 from being completely exposed to the outside. A limited opening 11 is provided on the surface of the reinforcement shell 10. When the device is used, the steel cable 4 is located inside the limited opening 11. The limited opening 11 limits the range of movement of the steel cable 4 during the lifting process to prevent the steel cable 4 from shaking and deviating.

[0025] The side of the cross mounting frame 5 away from its own center point is fixedly connected with an external limit assembly 6. When the lifting device is used, the external limit assembly 6 is in close contact with the surface of the pipe. The side of the cross mounting frame 5 away from the steel cable 4 is fixedly connected with an internal limit assembly 19. When the lifting device is used, the internal limit assembly 19 is in close contact with the inner wall of the pipe. The cross mounting frame 5, the internal limit assembly 19, and the external limit assembly 6 form a cross clamping mechanism. The external limit assembly 6 is composed of a spring rod 21 and an external flat plate 20. The internal limit assembly 19 is composed of a mounting block 8, an automatic telescopic rod 9, and an internal flat plate 18. The internal limit assembly 19 cooperates with the external limit assembly 6 to improve the lifting stability through the double-layer restriction structure.

[0026] The external flat plate 20 and the internal flat plate 18 are fixedly connected to the external rubber pad 12 and the internal rubber pad 7 on the opposite sides thereof. The existence of the external rubber pad 12 and the internal rubber pad 7 reduces the wear effect between the lifting device and the pipeline. The internal rubber pad 7 is provided with a docking groove 15 on the side away from the internal flat plate 18. When the device is not in use, the external flat plate 20 is located inside the docking groove 15. The docking groove 15 forms an air pressure adsorption effect when the internal limit assembly 19 is built in. When the device is stored, the docking groove 15 stores the external rubber pad 12 to prevent excessive dust from accumulating in the part where the device contacts the pipeline.

[0027] Working principle: First, fully retract the automatic telescopic rod 9, then pull the external flat plate 20 to clamp the external limit component 6 with the outer surface of the pipe, and then control the extension of the automatic telescopic rod 9 to clamp the internal limit component 19 with the inner wall of the pipe. After the docking groove 15 on the surface of the internal rubber pad 7 is compressed, the internal rubber pad 7 has the same function as the compression suction cup, which can further improve the stability of the internal limit component 19 after clamping, and then the lifting work can be carried out.

[0028] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
