Belt deviation intelligent correcting system and correcting method for belt conveyor

Abstract

The invention discloses a belt deviation intelligent correcting system and a belt deviation intelligent correcting method for a belt conveyor. Belt deviation detection devices are arranged at the head part, in the middle and at the tail part of a belt; the belt deviation detection devices output signals, the signals output by the belt deviation detection devices are connected with a control unit by A/D (Analog to Digital) conversion, the control unit outputs signals, and the signals output by the control unit are connected with deviation regulation screw drivers to drive deviation regulation rollers by A/D conversion; each belt deviation detection device comprises a posentiometric displacement transducer which is arranged on a belt frame and is formed by a slider and a winding; the middle part of each slider is provided with a fixed shaft; one end of each slider is in line contact with the corresponding winding and the other end of the slider is connected with the tail part of a movable sliding rod which is provided with a roller at the head part and is sleeved with an automatic return spring and one end of the automatic return spring; the rollers are arranged at one side of the belt to be in contact with the belt; the other ends of the automatic return springs are fixed on a frame at the other side of the belt; and when the belt is deviated, the rollers push the sliding rods to move to drive the sliders to slide on the windings by taking the fixed shafts as the centers and voltage difference signals are generated and are output to the control unit by A/D conversion.

Description

technical field [0001] The invention relates to an intelligent correction system and a correction method for belt deviation of a belt conveyor. Background technique [0002] In mining production, the transportation of minerals mainly uses belt conveyors to transport materials. In industrial sites, there are a large number of belt conveyors in use. Belt deviation has always been a common problem in the belt transportation process, which has not been well solved so far. The deviation of the belt will cause problems such as spillage, belt wear, idler roller and frame wear during material transportation. The spilled materials cause a heavy workload for the on-site staff and deteriorate the working environment, and the spilled materials will aggravate the wear or scratch of the belt, which will affect the service life of the belt. Now in order to ensure the normal operation of the belt, it is necessary to conduct regular inspections at the post to ensure that the belt is in go...

AI Technical Summary

Problems solved by technology

This device cannot intelligently adjust the belt deviation at any time. Only when the belt deviation is serious, stop the belt and adjust the deviation mainly by the on-site personnel to manually adjust and because the belt cannot be adjusted in time, it is easy to cause the material on the belt to spill due to the deviation of the belt, resulting in Belt wear and head wheel, tail wheel damage and increase the workload of on-site personnel
