Mining anti-overspeed conveying trolley

Abstract

The invention discloses a mining anti-overspeed conveying trolley. The mining anti-overspeed conveying trolley comprises a track body and a trolley body arranged on the track body in a sliding mode; a connecting rod is inserted into the front side of the trolley body in a sliding mode; the end of the connecting rod is fixedly connected with a gas collecting hood; an extensible spring is fixedly connected between the other end of the connecting rod and the inner wall of the trolley body; a push plate is inserted into the lower side wall of the vehicle body; a compression spring is fixedly connected between the upper end of the push plate and the inner top wall of the vehicle body; and a limiting opening is formed in the outer wall of the push plate. Reverse resistance is formed when the speed of the vehicle body is excessively high by arranging the gas collecting hood, an inward moving trigger push plate is pushed to move downwards, so that a friction plate is in contact friction with a speed reduction block, the speed of the vehicle body is controlled by reducing the moving speed of the friction plate and the vehicle body, personnel injury caused by ore and coal flying out due to follow-up sudden stop is avoided, and when a steel wire rope is broken, the vehicle body is fixed through magnetic adsorption between an electromagnet and a magnet plate, so the safety coefficient is increased.

Description

Technical field [0001] The present invention relates to the field of coal mine mechanical technology, and more particularly to a mining anti-microcarcell transport cell. Background technique [0002] Mine transport trolley generally refers to a special vehicle for mineral track body transportation. It is a narrow rail railway handling vehicle that transports coal, ore and waste stone, etc., which is generally used to use locomotives or winches. [0003] The conveying trolley moves along the mine track body for transporting, but there is a speed of the truck speed, or even disengage control during transportation, or even detachment, can not be carried out in time, and the end of the track body It is easy to cause the body and the flying of the car body and coal, ore, etc., thereby pose a threat to the lives of surrounding staff. Inventive content [0004] It is an object of the present invention to solve problems in the background technique, and a mining anti-microfair transport ...

AI Technical Summary

Problems solved by technology

[0003] The conveying trolley slides up and down along the mine track body for conveying work. However, during the transportation process, the trolley may overspeed and slide due to locomotives or winches, or even get out of control. It cannot stop or decelerate in time, and hits the end of the track body. In the end, it is easy to cause the car body, coal, ore, etc. to fly out, which will threaten the lives of the surrounding staff.
