Electromechanical liquid intelligent combined belt breakage protective device for belt conveyor

Abstract

The invention discloses an electromechanical liquid intelligent combined belt breakage protective device for a belt conveyor, which belongs to the technical field of mining machinery. The electromechanical liquid intelligent combined belt breakage protective device comprises an integral belt breakage protective device and multiple belt breakage capturers, wherein the integral belt breakage protective device is positioned near a nose and fixed on a base through foundation bolts; and the belt breakage capturers are distributed at the upstream and downstream of the integral belt breakage protective device and fixed at the upper part of a belt stand through a bolt set. The electromechanical liquid intelligent combined belt breakage protective device has the beneficial effects that the integral belt breakage protective device is adopted in the position where the tension of the nose is maximum and belt breakage is liable to occur; the capturing speed is high, the capturing force is large and capturing is more reliable; and the multiple belt breakage capturers are adopted at the upstream and downstream of the integral belt breakage protective device of the nose, thereby solving the random breakage capturing problem of a belt and overcoming the problem of large capturing dead zone of the integral belt breakage protective device.

Description

technical field [0001] The invention relates to a mine equipment, in particular to a broken belt protection device applied to a coal mine inclined shaft (lane) belt conveyor, which can be used as a belt cassette when needed. Background technique [0002] As an important transportation equipment, the belt conveyor is widely used in some links of coal mine production and transportation, and plays a huge role. Due to the long-term operation of the tape and various accidental factors (poor quality of vulcanized joints or poor quality of tape production, etc.), broken tape accidents occur from time to time. The harm of flat belt belt conveyor is not obvious after the belt is broken, but because the upper belt conveyor, especially the upper belt conveyor used as the main lifting, has a large inclination angle, long belt and heavy load, once a broken belt accident occurs, It will cause great harm: damage to the idler bracket, causing the idler to fly horizontally; cause the be...

AI Technical Summary

Problems solved by technology

There are two types of broken belt arresters currently used most in China, one is a broken belt catcher, and the other is an integral broken belt protection device. Their disadvantages are: the broken belt catcher must achieve a high safety factor , the number of catchers must be arranged in a high density, so that it is easy to give the catch signal by mistake, resulting in misoperation and too much maintenance. In addition, most of the existing broken belt catchers are purely mechanical, and the misoperation rate is very high.

The number of integrated broken belt protection devices is small. For the entire belt, there is a possibility of broken belts at any position, so the blind area for catching is too large. In addition, the existing integral broken belt protection devices are all one-time braking. Without cushioning, it is easy to cause secondary breakage of the belt, especially for the down belt, which is particularly important
