Damage monitoring device and method of conveyer belt of belt conveyer

Abstract

The invention relates to a damage monitoring device and method of a conveyer belt of a belt conveyer. The damage monitoring device of the conveyer belt of the belt conveyer comprises the conveyer belt, a material bearing body arranged above the conveyer belt, a support used for supporting the material bearing body, a roller, a plurality of carrier rollers and upper carrier roller frames used for fixing the carrier rollers. The upper carrier roller frames are arranged on the lower side of the conveyer belt. The carrier rollers are located on the lower side of the conveyer belt and make contact with the bottom face of the conveyer belt. The material bearing body is installed above the conveyer belt and is a material bin or a chute or a hopper. Sensors are installed on the shell of the material bearing body or an additional structure fixedly connected to the shell, and each sensor measures the motion or state of one part of the material bearing body; or a sensor measuring the motion or state of one part of the material bearing body is installed on a component not connected with the material bearing body. The damage monitoring device and method of the conveyer belt of the belt conveyer are high in flexibility, low in false alarm rate and quite short in delay; and the adopted equipment and devices have quite high adaptability to the working conditions and are almost free of maintenance.

Description

technical field [0001] The invention relates to a conveyor belt damage monitoring device and method of a belt conveyor, belonging to the technical field of automatic detection, and the device can be applied to a belt conveyor. Background technique [0002] Belt conveyor is the most widely used transportation machinery in industrial production. Conveyor belt longitudinal tearing accident is the most serious conveyor belt damage. In production, the conveyor belt is often cut longitudinally due to the large pieces of material or steel mixed in the material transported by the belt conveyor. If it is not detected in time and stopped in time, the tear length will increase, resulting in huge economic losses. loss. and must be discontinued for repair. There are many forms of longitudinal tear monitoring devices on the market now, such as cable-blocking type, piezoelectric induction type, discharge port flap type, photoelectric type and so on. These monitoring and protection devi...

Problems solved by technology

[0015] The present invention is a conveyor belt damage monitoring device and method for a belt conveyor. Its purpose is to solve the problems of high false alarm rate and low sensitivity in the above-mentioned prior art that cannot be practically implemented, thereby disclosing a method for detecting the initial time of longitudinal tearing. The conveyor belt damage monitoring device and method of the belt conveyor that can issue an alarm signal due to the occurrence of several characteristics that can be distinguished from normal operation
