Longitudinal tear detection device and method for conveying belt

Abstract

The invention belongs to the technical field of tear detection of conveying belts, and relates to a longitudinal tear detection device and method for a conveying belt. The device comprises a signal transmitting unit, a signal receiving unit and a matched computing, analyzing and processing unit, wherein the signal transmitting unit is arranged on the upper side of a lower belt body of the conveying belt, and the signal receiving unit is arranged on the lower side of the lower belt body of the conveying belt. The signal transmitting unit comprises a transmitting end mounting plate connected with a synchronous drive mechanism and X-ray tubes arranged on the transmitting end mounting plate. The signal receiving unit comprises a receiving end mounting plate connected with the synchronous drive mechanism and X-ray receivers which are arranged on the receiving end mounting plate and matched with the X-ray tubes. The X-ray tubes and the X-ray receivers move synchronously through the synchronous drive mechanism. Improving is carried out on the structures and working manners of the signal transmitting unit and the signal receiving unit, the longitudinal tear condition of the conveying belt is detected in real time, alarm signals are sent out in time, further development of the tear condition of the conveying belt can be effectively postponed, and a good protection effect on the conveying belt is achieved.

Description

technical field [0001] The invention belongs to the technical field of conveyor belt tear detection, and in particular relates to a conveyor belt longitudinal tear detection device and a detection method. Background technique [0002] At present, most of the conveyor belts use X-ray machine static detection to predict their safety performance and service life. Although this kind of detection instrument is intuitive, production must be stopped during detection, and real-time online detection cannot be realized. In addition, manual operation is labor-intensive, low in efficiency, and takes a long time to detect, and the long-term exposure of X-rays will damage the body of the inspector, and the full-length test of the conveyor belt cannot be realized, so that the defects of the conveyor belt cannot be found in time. Therefore, how to design a simple, reliable, and high-efficiency conveyor belt tearing on-line detection device is one of the current important research and develo...
