AI Technical Summary
Existing pipe pulling equipment causes the joint pipe to slip when clamping it due to reduced friction caused by moisture and soil particles on the outer wall of the joint pipe. This affects the construction quality and efficiency, and increasing the clamping force may cause the joint pipe to deform and be damaged.
The connector tube is alternately clamped by a ring support base, a first clamping device, and a second clamping device. The connector tube is slowly pulled out by a hydraulic push rod, while a hot air pipe is used to blow away the attached moisture and soil particles to ensure clamping stability.
This allows for the stable and slow extraction of the connector pipe, preventing slippage and deformation, and improving construction quality and efficiency.
