Method and device for material tracking and slipping detection for feeding belt

Abstract

The invention discloses a method and device for material tracking and slipping detection for a feeding belt. The device comprises a material conveying roller, a return roller and a conveying belt, wherein a speed measuring gear is arranged at one end of the return roller, a sensor is arranged on an outer machine frame of the return roller, and the speed measuring gear and the sensor are arranged in the same plane in the vertical direction. According to the method for material tracking and slipping detection for the feeding belt, the same speed sensor is matched with a single-chip microcomputer, a function relation between the speed and time and a function relation between the speed and displacement are utilized to realize simultaneous monitoring of the material tracking and the slipping detection; furthermore, in the method, multiple zero clearing steps are established, accumulative errors are eliminated, so that the data accuracy of the whole process is ensured; and detection pulse precision can be adjusted according to on-site belt working condition requirements so that universality between the belts with different rotating speeds can be ensured.

Description

technical field [0001] The invention belongs to the field of belt conveying, and in particular relates to a method and a device for material tracking and slip detection of a feeding belt. Background technique [0002] In the field of industrial automation, the belt conveyor is a commonly used solid material conveying equipment. In steelmaking production, the auxiliary raw materials and ferroalloy raw materials need to be transported to the furnace top silo through the belt. Among the safety accidents caused by the feeding belt, belt slippage is one of the most common failures of belt conveyors. Belt slippage will cause the motor to run idly, and materials will accumulate at the front end of the belt, which may cause different serious consequences. In order to ensure the safe and reliable operation of the belt conveyor, it is very important to detect the belt slipping fault accurately, timely and sensitively. Although there are various kinds of skid detection and alarm devic...
