Description
Technical Field
The invention belongs to the technical field of mines, and particularly relates to an automatic deviation rectifying device of a mining belt conveyor.
Background
Mining conveyor belt conveyors refer to conveyor belt conveyors used in the mining, production, transfer, processing of minerals such as coal. The mining conveyor belt conveyor has the characteristics of large conveying capacity, complex working environment, strong bearing capacity, long conveying distance and the like, and is widely used in all main mining areas in China. The mining conveyor belt conveyor can be used not only in the process of mineral mining, but also in the process of mineral processing. In the aspect of energy consumption, the mining conveyor belt conveyor can effectively reduce energy consumption, improve economic benefits, and can save energy and protect the environment compared with transportation modes such as automobiles and the like. In addition, the mining conveyor belt conveyor has the characteristics of small maintenance amount, simple maintenance and the like in the aspect of maintenance, and is popular with mineral processing enterprises.
In actual use, due to the reasons of installation quality, transmission belt tension, surface roughness of guide rollers and the like, the phenomenon of transmission belt deviation often occurs in a mining transmission belt conveyor. Firstly, the deviation of the transmission belt can directly cause the uneven stress on the two sides of the transmission belt, and the uneven stress can cause the service life of the transmission belt to be shortened along with the lapse of time. In extreme cases, when the side edge of the conveyor belt passes over the edge of the guide roller (driving roller or driven roller), the conveyor belt rubs against the edge of the guide roller during operation, thereby accelerating its damage. Secondly, especially for a mining conveyor belt conveyor adopting a flat belt, the deviation of the conveyor belt can cause the problems of mineral falling, unstable operation of the conveyor and the like.
The prior art includes multiple technical schemes for solving the problem of deviation of a transmission belt. The technical schemes are mainly divided into two types, one type is that an independent deviation adjusting roller is arranged on a conveyor belt, and when the deviation of the conveyor belt is detected, the deviation adjusting roller is utilized to act on the side edge of the conveyor belt so as to force the conveyor belt to return to the central position. Another type is to provide the movable guide roller of the conveyor belt with a lifting device, and when the deviation of the conveyor belt is detected, one side of the movable guide roller (i.e., the side of the conveyor belt facing the deviation thereof) is lifted by the lifting device, so as to force the conveyor belt to return to the normal operating position.
However, the above solution still has problems. Specifically, the deflection roller applies a force to the side of the conveyor belt while rubbing against the conveyor belt, which over time results in accelerated wear of the side of the conveyor belt. Furthermore, in the case of a flat belt conveyor, the lifting device can cause the conveyor belt to tilt, which can cause minerals to fall off during the correction operation, and can also cause overcorrection.
Therefore, the automatic deviation rectifying device for the mining belt conveyor is provided, abrasion to a transmission belt is avoided, mineral falling and excessive deviation rectification caused in deviation rectifying operation are avoided, the whole structure is simpler, the cost is lower, and the problems in the prior art are solved.
