Intelligent control device and method for preventing conveyor belt from deviating

Abstract

The invention relates to an intelligent control device and method for preventing a conveyor belt from deviating. A lower joist is fixed to a conveying rack, a bearing set is connected with the lower joist, a swing bracket is inserted into the bearing set to be fastened after being connected with a rotating shaft in a welded mode, a gear is installed at the tail end of the rotating shaft and fixed, a gear is installed on a shaft head of a servo motor, the gear at the tail end of the rotating shaft is engaged with a servo motor shaft head gear in a relative tooth mode, a driver is placed on the lower joist, and two ultrasonic distance measuring sensors are installed at the two ends of the swing bracket respectively. The three rollers form a roller set, the conveyor belt runs on the roller set, a roller supporting base is connected with the swing bracket, and the three rollers are connected with the roller supporting base. A PLC is electrically connected with a driver and the two ultrasonic distance measuring sensors, and the driver is electrically connected with the servo motor. The intelligent control device and method have the advantages that the deviation amount is intelligently detected in a non-contact mode, the edge of the conveyor belt is not abraded, the deviation correcting amount is intelligently matched, reliability is high, and maintenance is not needed.

Description

technical field [0001] The invention relates to a conveyor belt, in particular to an intelligent control device and control method for preventing the conveyor belt from running off. Background technique [0002] Conveyor belts are widely used in the transportation of bulk materials in various factories and mines, and there is usually a certain deviation phenomenon, which is caused by various factors. Such as: belt joint handover is not correct, frame is not correct, roller sticking material, idler roller operation is not flexible, etc. In view of the above-mentioned belt deviation situation, at present, mechanical self-aligning idlers or hydraulic deviation-correcting idlers are mainly used to control belt deviation. The mechanical self-aligning idler rollers rely on the vertical rollers on both sides of the conveyor belt to push the edge of the conveyor belt to achieve the purpose of controlling the deviation. The hydraulic correction idler drives the oil pump to rotate t...

AI Technical Summary

Problems solved by technology

Both methods act on the edge of the conveyor belt. Over time, the edge of the conveyor belt will crack, which affects the normal service life of the conveyor belt

At the same time, these two methods of correcting the deviation of the conveyor belt also have the problem of insufficient or excessive deviation correction, and cannot accurately calculate the deviation of the conveyor belt
