Group control method for deviation rectification of conveyor belt and detection and correction system thereof

Abstract

The invention provides a group control method for deviation rectification of a conveyor belt. The method comprises the specific steps: firstly, arranging multiple sets of deviation detection assemblies according to the length and the deviation position of the conveyor belt, and arranging corresponding deviation rectification assemblies at the upstream distance H of the conveyor belt; when the deviation detecting assembly detects that the deviation displacement S of the position exceeds the set deviation displacement S1, sending, by the control assembly, an instruction to control an actuator ofthe corresponding deviation correcting assembly to act to the preset position, and when an angle sensor in the deviation correcting assembly detects the rotating angle of a carrier roller set in thecurrent deviation correcting assembly, correcting, by the deviation correcting assembly, the deviation of the carrier roller set. and feeding back, by the deviation rectifying assembly, the information to the control assembly and comparing, by the deviation rectifying assembly, the information with a set value, and controlling the actuator to conduct corresponding actions, so as to complete coupling closed-loop control over the deviation rectifying assembly. The invention further provides a detection and correction system applied to the group control method for deviation rectification of the conveyor belt, the conveyor belt can be rapidly and automatically corrected when deviating at any position of one or more positions through group control, and the deviation correction effect on the conveyor belt during transportation under complex working conditions is improved.

Description

technical field [0001] The invention relates to the field of deviation correction control of belt conveyors, in particular to a group control method for deviation correction of conveyor belts and a detection and correction system thereof. Background technique [0002] In recent years, with the wide application of belt conveyors with large flow, long distance and high belt speed, the conveying efficiency of bulk materials has been greatly improved. During the operation of the belt conveyor, the conveyor belt is subjected to various eccentric forces, causing its axis to deviate from the center line of the conveyor and deviate to one side. This phenomenon is called the deviation of the conveyor belt. At present, the deviation of the conveyor belt is one of the main reasons for the sudden shutdown of the belt conveyor, material spreading, blockage of the frame, and shortening of the service life of the conveyor belt. It not only affects the production of enterprises, but also ca...

Problems solved by technology

This method can realize the function of automatically adjusting the deviation of the belt in the short-distance, small-flow, and single-material belt transportation of coal handling equipment in thermal power plants. Under these conditions, it is often affected by various eccentric forces. Using a single mechanism to control the deviation of the long-distance conveyor belt will not be able to provide the return force required for the deviation of the long-distance conveyor belt, so that the ideal deviation correction effect cannot be achieved.
