AI Technical Summary
The existing PCCP pipe installation pull-out device cannot adapt to the laying of pipes of different lengths and diameters.
A device was designed that includes a first main beam, a telescopic device, wheels, limiting legs, a motor, a reel, and a limiting beam. The telescopic device and wheels adapt to different diameters, the limiting legs and the limiting beam adapt to different lengths, the motor drives the reel to collect steel wire ropes for traction, and the limiting beam adapts to different diameters through limiting pins and sliders.
It achieves adaptability to the laying of PCCP pipelines of different lengths and diameters, ensuring stable movement and traction of the device within the pipeline, and providing safety protection.
