Safety warning signal system for lifting transportation of inclined roadway track of coal mine

Abstract

The invention discloses a safety warning signal system for lifting and transporting a coal mine inclined roadway track, which comprises the following steps that: each horizontal parking lot entrance car door state sensor provides real-time signals of'opening 'and'closing' for the opening and closing states of each horizontal parking lot entrance car door, and provides the signals to a signal control box through a cable; each horizontal inclined drift blocking door state sensor provides opening and closing real-time signals for the opening and closing state of each horizontal inclined drift blocking door, and provides the signals to the signal control box through a cable; and each horizontal parking lot track switch device position state sensor provides a real-time signal for the position state of each horizontal parking lot track switch device. Transportation accidents caused by state errors of the turnout and the vehicle blocking door due to human factors can be fundamentally eradicated, the lifting safety of multi-level rail lifting and transportation of the inclined roadway of the coal mine can be greatly improved, and the safety coefficient and the working efficiency are improved.

Description

Technical field [0001] The present invention relates to the field of coal mine tilt roadway track lifting and transportation technology, and in particular, there is a safety warning signal system for booster transportation transportation for coal mines. Background technique [0002] Traditional improvement of transportation, various horizontal stalls entrance vehicle shutter door, each horizontal diagonal trunk door, each horizontal car track Tutor operation is performed by the signal of each horizontal car field to manually set the hookworks, hoist drivers Unable to visually obtain status information of each horizontal car entrance vehicle door, each horizontal diagonal vehicle door, each horizontal car track trench is turned on and closed. For example, when the signal transmits the hook industry in the 4-horizontal street, the slope of the 1, 2, 3 horizontal car field must be set to open state, 1, 2, 3 horizontal stamp's entrance vehicle door must be closed State, the rail trig...

AI Technical Summary

Problems solved by technology

There are many levels of operation and complex operation, and it is very easy to cause human-made operation errors to cause transportation safety accidents caused by wrong opening and closing states of turnouts and car doors.

[0003] The existing lifting transportation conditions cannot provide hoist operators with intuitive information on the opening and closing status information of the parking doors at the entrance of each horizontal parking lot, the parking doors of each horizontal inclined lane, and the track switches of each horizontal parking lot. Relying on the signals of various levels of yards to combine the information provided by hook workers, human factors are likely to mislead the operation, the reliability is not high, and the risk of improving transportation safety is high
