A warning device for mine transportation roadway

Abstract

The invention relates to a mine haulage roadway warning device. The mine haulage roadway warning device comprises a controller, a warning fence, an early-warning reminding unit, a lifting transmission device and an air compression device. An action triggering signal module is connected with the input end of the controller, and the output end of the controller is connected with the early-warning reminding unit through a signal line. The lifting transmission device and the air compression device are connected with the controller through signal lines. The warning fence is connected with the lifting transmission device through a steel wire rope. The mine haulage roadway warning device is simple in structure, reasonable in design and good in warning effect, has the full-automatic warning effect and greatly increases the safety factor of inclined roadway haulage.

Description

technical field [0001] The invention relates to a power protection device for mine transportation roadway, in particular to a warning device for mine transportation roadway with simple structure, reasonable design and good early warning effect. Background technique [0002] At present, most of the warning and protection devices for mine transportation roadways are mechanical automatic recovery warning ropes. Through the cooperation of manual lifting and red light opening and stopping, the warning purpose of "no driving and no pedestrians" in the transportation roadway can be realized. However, there are the following problems in the use of the mechanical automatic recovery warning rope: ①If the installation is too low, sometimes the warning rope is forgotten to be retracted after the inclined lane transportation stops, and the vehicle is easy to crash it; The position is not obvious, causing people to accidentally enter the warning rope, which is likely to cause safety accid...
