AI Technical Summary

Technical Problem

Existing belt conveyors used in coal mines lack support after deployment, causing the conveyor belt to be partially suspended and tilted, affecting the stability of coal transportation.

Method used

A control system for a belt conveyor used in coal mines was designed. By setting limit guide rails and support rods on both sides of the conveyor belt, the length of the conveyor belt is adjusted by using telescopic sleeves and telescopic rods, and the length adjustment is achieved by combining the contact between the friction plate and the wing plate, thus ensuring the smooth unfolding of the conveyor belt.

Benefits of technology

This effectively avoids the problem of the conveyor belt being suspended and tilted after being extended, ensuring the stability and safety of coal transportation.

Abstract

The utility model belongs to the technical field of coal mine transportation, and relates to a control system of a belt conveyor for a coal mine, which comprises a conveying belt, a power belt wheel arranged on an inner ring of the conveying belt, a reversing belt wheel arranged at the other end of the inner ring of the conveying belt, and a tensioning belt wheel and an adjusting belt wheel arranged in the middle of the inner ring of the conveying belt. Limiting guide rails are arranged below the two sides of the conveying belt. According to the control device of the belt conveyor for the coal mine, firstly, a friction plate is separated from a wing plate, the variable length of a length driving telescopic rod is adjusted, the length needing to be adjusted is equally divided into the number of telescopic sleeves on the single side, the variable length of the telescopic sleeves is determined, and adjustment is started from the telescopic sleeve on one side of a power belt wheel; and after the adjustment is finished, the friction plate is in contact with the wing plate, so that the length of the conveying belt can be adjusted while the distribution distance of the belt supporting rollers is changed, and the problem that the conveying belt is partially suspended and is easy to incline after being extended is avoided.
