[0002] In mines, equipment and items are generally transported along underground mine tracks by transport vehicles. Among the transport vehicles, flatbed trucks have no power of their own and need to be towed by a tractor. The flatbed truck is moved along the track by being dragged or pulled by the tractor.

[0003] When a traction rope is used to drag a transport vehicle on a track, the traction rope may break due to prolonged use or excessive load. After the traction rope breaks, the speed of the transport vehicle on the slope will be out of control, causing the transport vehicle to rush along the slope to the bottom of the mine, resulting in casualties and property losses.

The present application implements a system for preventing derailment of inclined shaft transport vehicles, thereby solving the problem that when the traction rope breaks while the transport vehicle is moving on the slope in the mine, the transport vehicle can be stopped on the track when the transport vehicle moves downward on the track, thereby avoiding casualties and property losses.

When the transport vehicle moves at a constant speed, the intervals at which the signal receiving blocks receive signals are the same. When the traction rope is disconnected, the speed of the transport vehicle loses control. After receiving the signal, the controller controls the operation of the winder, and the brake block contacts the guide rail to stop the transport vehicle. This effectively solves the problem in the prior art that the speed of the transport vehicle loses control after the traction rope breaks, causing the transport vehicle to rush to the bottom of the mine along the slope, causing casualties and property losses. This ensures that the transport vehicle stops on the track when it slides downward on the track. BRIEF DESCRIPTION OF THE DRAWINGS
