Automatic detection and adjustment device and method for preventing breakage and slippage of long-conveying-distance conveying belt

Abstract

The invention discloses an automatic detection and adjustment device and method for preventing breakage and slippage of a long-conveying-distance conveying belt. The device comprises a mechanical part and a measurement and control part, wherein the mechanical part comprises a conveying belt, a transmission system, a drive drum, a turnabout drum, a conveying belt tensioning mechanism, a supporting mechanism and an automatic tension adjustment device; the measurement and control part comprises a signal acquisition module and a PLC (Programmable Logic Controller) automatic detection and control module; the signal acquisition module is used for acquiring data signals of a tension of a conveying belt, a speed of the conveying belt and a speed of the drive drum and conveying the data signals to the PLC automatic detection and control module; the PLC automatic detection and control module sends an instruction to the automatic tension adjusting device and a motor of the drive drum and adjusts the tension of the conveying belt and the speed of the drive drum respectively. According to the automatic detection and adjustment device and method, a relationship between slippage and breakage faults of a conveying belt of a belt conveyor is established, the variation of the tension of the conveying belt is detected while the slippage is detected, and therefore the breakage problem caused by excessive adjustment of a tension adjustment device is avoided.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an automatic detection and adjustment device and method for preventing breakage and slippage of long-distance conveyor belts, mainly used for automatic detection and adjustment of the tension and running speed of belt conveyor belts for long-distance transportation , Realize the timely prevention and adjustment of long-distance conveyor belt breakage and slippage. Background technique [0002] A belt conveyor is a friction driven machine that transports material in a continuous manner. It is mainly composed of frame, conveyor belt, idler roller, driving drum, reversing drum, tensioning device, transmission system, etc. The transmission system includes the drive roller motor, the motor drives the drive roller to rotate, the friction between the drive roller and the conveyor belt drives the conveyor belt to run, and the running direction of the conveyor belt is changed by reve...

AI Technical Summary

Problems solved by technology

[0007] To sum up, at this stage, long-distance conveyor belts have a certain detection technology for conveyor belt breakage and slippage, but they have not connected the two, and the tension factors that cause conveyor belt breakage and slippage have not been self-adaptive. The adjustment, lack of a certain ability to predict and adjust in time, the degree of automation is not high
