Description

Technical Field

[0001] This utility model relates to the technical field of early warning and protection equipment for coal mining machines, and in particular to an early warning and protection device for coal mining machines with cable protection. Background Technology

[0002] In the production of fully mechanized mining (loosening) faces, mobile substations and pump stations provide power and hydraulic power to the face equipment. Numerous cables and hydraulic pipelines enter the face through mobile substations, pump stations, monorail cranes, the exit on the face, and the tail of the front conveyor.

[0003] In the production operation of fully mechanized mining faces, after the coal mining machine has cut through the coal wall at the upper end, it can continue to move forward for a certain distance to carry out coal loading operations. At this time, the cables and hydraulic pipelines of the coal mining machine drum are close to the upper end outlet, which can easily cause accidents that cut the cables and hydraulic pipelines, resulting in major electromechanical accidents and economic losses.

[0004] To address the problem that existing early warning and protection devices for coal mining machines are prone to cutting cables and hydraulic lines near the upper end of the mining machine drum, potentially causing major electromechanical accidents and economic losses, this new early warning and protection device for coal mining machines uses magnetic proximity switches and moving magnets installed on the mining machine and track. This allows for the detection and early warning of the mining machine's position. When the moving magnet approaches the magnetic proximity switch, an alarm is triggered, alerting the mining machine operator that the machine has reached its limit position, preventing further operation that could damage the cables. Utility Model Content

[0005] In order to overcome the problem that existing early warning and protection devices for coal mining machines can easily damage cables and hydraulic pipelines near the upper end of the coal face during coal mining operations, causing major electromechanical accidents and economic losses, the coal mining machine can continue to move forward a certain distance for coal loading operations after cutting through the coal wall at the upper end.
