Description

Automatic power-off device for shuttle car Technical Field The utility model relates to the technical field of shuttle car auxiliary machinery, in particular to an automatic power-off device of a shuttle car. Background The shuttle car is one kind of conveying and storing equipment for discharging slag and loading ore for tunnel, mine, water diversion tunnel, petroleum pipeline, natural gas pipeline, tunnel driving and mining. Generally, a mining shuttle car mainly comprises a groove-shaped carriage and a walking part of a conveyor, and runs on a rail to advance under the traction action of a traction electric locomotive. With the gradual popularization of continuous mining and anchor digging processes, new safety problems are increasingly developed. In the mining construction environment, a shuttle car traverses back and forth along a coal mine tunnel in the production process of a tunneling team. Particularly in double lane driving, the shuttle car may also need to turn around with the tunnel. Because the remote control of the shuttle car cannot be realized by utilizing the existing mining facilities, great potential safety hazards exist. For example, when an operator enters a work surface, the shuttle is likely to be in an operational state, in which case the operation of the shuttle is likely to cause physical injury to the operator. In recent years, accidents of hurting people caused by incapability of timely controlling the operation of a shuttle car are frequently and frequently seen in mining areas. In the existing continuous mining, digging, anchoring and tunneling processes, a passive management mode is adopted for the use of the shuttle car. Generally, when knowing that an operator needs to enter a working surface under a mine, the operator needs to be provided with a shuttle driver, and the shuttle driver directly controls the operation of the shuttle to ensure the safety of the operator. However, even the artificial passive management mode has a certain potential safety hazard, so we propose an automatic power-off device for the shuttle car.
