Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to an auxiliary device for slippage protection testing of underground belt conveyors. Background Technology

[0002] A belt conveyor is a continuous transportation device that uses a circular conveyor belt to circulate between drive and driven drums, enabling efficient, long-distance material transport. The belt conveyor protector is crucial for ensuring the safe and efficient operation of the equipment. Its core functions are fire prevention and belt protection, and it also includes multiple protective functions such as anti-deviation, anti-slip, anti-tear, overheating, smoke protection, water spraying, tension reduction, anti-reverse rotation, braking, and emergency stop along the conveyor line.

[0003] Belt conveyor protection falls under the category of major risk management in coal mines. Therefore, daily maintenance requires testing of various protection systems to ensure their proper functioning and reliability. The belt conveyor slippage protection system uses a small roller and speed sensor installed on the lower belt surface. Daily slippage tests require starting the belt conveyor, and maintenance personnel must stand beside it and manually retract the roller to activate the slippage protection. During this process, the distance between personnel and operating equipment is very small, failing to meet safety requirements and posing a high safety risk. Therefore, this invention proposes an auxiliary device for testing slippage protection of underground belt conveyors to address the shortcomings of existing technologies. Utility Model Content
