Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for mine pipelines, specifically to an automatic extension device for a loading and unloading aid for pipelines. Background Technology

[0002] The underground pipeline used in the mine is 6 meters long and is mainly transported into and retrieved from the mine by an 8-ton explosion-proof articulated material truck. The truck's external dimensions are 8.03 meters long, 1.96 meters wide, and 2 meters high, with the trough being 4.3 meters long.

[0003] During loading and unloading of pipes, at least 1.7 meters extend outward from the trough, making the pipes prone to slipping. After the pipes are loaded and tied, the lowest point is about 0.6 meters off the ground, especially the end of the flexible hose, which is about 0.3 meters off the ground. This causes the vehicle's overall center of gravity to shift backward, reducing the vehicle's longitudinal stability while driving in the alley. The trough floor plate deforms, and the chain hoisting is at risk of breaking. When encountering sharp turns, the pipes are prone to slipping, posing a safety hazard to auxiliary transportation.
