Description

Technical Field

[0001] The utility model relates to the technical field of power cable protection pipe processing, and particularly relates to a traction device for power cable protection pipes. Background Art

[0002] The cable protection pipe with an inner diameter less than 50 mm can obtain the forward thrust from the pipe extruder. However, for the cable protection pipe with a large inner diameter, relying solely on the pipe extrusion equipment to obtain the forward thrust is not sufficient to gain the power for forward movement, and a traction device is also required to ensure the forward power after the pipe is formed. Summary of the Invention

[0003] The purpose of the utility model is to provide a traction device for power cable protection pipes to solve the problem of the forward movement power of large-diameter power cable protection pipes after being formed.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A traction device for power cable protection pipes, including a workbench 1, a pipe guiding ring 2, and a traction device 3. The pipe guiding ring 2 and the traction device 3 are successively located on the workbench 1 from left to right;

[0005] The pipe guiding ring 2 is circular;

[0006] The traction device 3 includes a balloon 31, a telescopic rod 32, a fan 33, and a baffle 34. The fan 33 is behind the baffle 34, the telescopic rod 32 is in front of the baffle 34, the baffle 34 is supported on the workbench 1, the balloon 31 is connected to the telescopic rod 32, and after the balloon 31 expands, it becomes an ellipsoid, and a check valve 311 and a safety valve 312 are provided;

[0007] When the power cable protection pipe is connected to the traction device 3, the power cable protection pipe is inside the pipe guiding ring 2; the fan 33 of the traction device 3 sucks air, the telescopic rod 32 of the traction device 3 is in a stretched state, and the balloon 31 is in an expanded state inside the end of the power cable protection pipe and tightly clings to the inner wall of the power cable protection pipe;

[0008] When the traction device 3 drives the power cable protection pipe to move forward together, the power cable protection pipe is inside the pipe guiding ring 2; the fan 33 of the traction device 3 deflates, the telescopic rod 32 of the traction device 3 is in a contracted state, and the balloon 31 is in an expanded state inside the end of the power cable protection pipe and tightly clings to the inner wall of the power cable protection pipe, dragging the power cable protection pipe.

[0009] The beneficial effects of the utility model are:

[0010] 1. The pipeline guiding ring 2 allows the power cable protection pipe to pass through, guiding the advancing direction of the power cable protection pipe so that it does not deviate from the track.

[0011] 2. The balloon 31 of the traction preparation 3 is inside the end of the power cable protection pipe. After expansion, it generates frictional force with the inner wall of the power cable protection pipe, thereby dragging the power cable protection pipe forward.

[0012] 3. After expansion, the balloon 31 is an ellipsoid to ensure a large contact surface with the power cable protection pipe after expansion, and a check valve 311 is provided to prevent the air release of the fan 33. When the telescopic rod contracts, the balloon 31 releases air, resulting in the inability to connect with the power cable protection pipe. BRIEF DESCRIPTION OF THE DRAWINGS
