Embodiment Construction

[0020] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0021] In order to realize the detection of the conveyor belt, the present invention provides such as figure 1 The shown conveyor belt longitudinal tear monitoring device mainly includes a vibration source 11 , a vibration signal receiving module 12 , and a vibration signal processing module 13 . The vibration source 11 is preferably a cam mechanism passive vibration source, and the cam mechanism passive vibration source utilizes the conveyor belt 10 to generate a stable frequency. The vibration signal receiving module 12 is preferably a vibration sensor, especially a pulley contact vibration sensor. Vibration signal processing module 13 such as figure 2 As ...

Abstract

The invention discloses a device and a method for monitoring longitudinal tear of a conveying belt. The device comprises a vibration source, a vibration signal receiving module and a vibration signal processing module. The vibration source is used for allowing the conveying belt to generate transverse vibration. The vibration signal receiving module is used for receiving vibration signals generated by the conveying belt under the action of the vibration source and transmitting the vibration signals to the vibration signal processing module. The vibration signal processing module is used for judging whether longitudinal tear occurs or not according to the vibration signals and controlling the conveying belt to stop when longitudinal tear occurs. By the device, the convey belt can be stopped timely when longitudinal tear of the conveying belt occurs, and accordingly safe production is guaranteed, safety accidents caused by longitudinal tear of the conveying belt can be avoided, and damage to conveying devices can be avoided.

Description

technical field [0001] The invention relates to a conveyor belt, in particular to a monitoring device and method for longitudinal tearing of a conveyor belt. Background technique [0002] Conveyor belts are widely used in mines, ports and docks, and are the main transmission equipment in material production and transportation. During the process of conveying materials, due to the increase of load, scratches by obstacles and aging, the steel core may be corroded, broken or joint elongation and other failures may occur. If such a failure occurs, it will cause major safety accidents or stop production, and will cause loss of transported materials or damage to equipment, resulting in huge economic losses and casualties, seriously affecting safe production. In the prior art, the commonly used conveyor belt detection scheme is to detect the steel rope core of the conveyor belt through computer X-ray detection technology, but this detection scheme is expensive, and X-rays may caus...
