Control system of underground rock transporter in inclined drift of coal mine

Abstract

The invention provides a control system of an underground rock transporter in an inclined drift of a coal mine. The control system comprises a transporter stopper arranged at an entrance end of a track, wherein a speed-reducing limit switch, a first transporter arrester, an anti-overwind sensor and a second transporter arrester are sequentially arranged on the track located behind the transporter arrester; the speed-reducing limit switch and an output end of the anti-overwind sensor are electrically connected with an input end of a PLC (programmable logic controller) respectively; an output end of the PLC is electrically connected with input ends of the first transporter arrester, the second transporter arrester and the transporter stopper respectively; and the PLC is connected with the rock transporter interactively and electrically. The control system can guarantee reliable operation of the rock transporter in an ascending process and a descending process of the inclined drift transport and guarantee the safety and high efficiency of the underground inclined drift transport, meets requirements for safety production of the coal mine inclined drift transport, reduces the accident probability and the economic loss, and improves the automation degree of operation of an underground transport vehicle.

Description

Technical field [0001] The invention relates to a coal mine underground transportation control device, in particular to a coal mine inclined roadway transportation control system. Background technique [0002] In our country, coal is the main energy source. The safe production of coal mines directly affects the development of the national economy, and well-mined coal mines need to be transported by carts. Due to the complex underground environment of coal mines, the terrain is undulating, curved and changing, and inclined roadways Longer, there is a certain risk when the mine truck is transported. Therefore, safety protection devices such as car stoppers are installed on the transportation track to avoid the phenomenon of sports cars during the operation of the mine car and cause serious safety consequences. The main phenomena of sports cars during the operation of running vehicles are as follows: ①The running state of the running vehicle is inconsistent with the running state o...
