Mechanical touching type conveyor belt tearing detection method

Abstract

In a mechanical touching type conveyor belt tearing detection method, a probe arranged on a rotating body rotating with a conveyor belt has a contact with the surface of a conveyor belt; when the probe contacts a tearing area of the surface of the conveyor belt, the probe is inserted into the slit in the surface of the conveyor belt via elasticity applied by an elastic element connected with the probe; when the probe is inserted into the slit, a triggering switch is triggered by a triggering mechanism connected with the probe; and a signal is sent to a processing unit by the triggering switch, so a tearing condition of the conveyor belt is determined. A detection process is simple and reliable; harmful effect on on-site equipment can be prevented; an alarm signal is produced when the probe is inserted into the conveyor belt slit; external interference such as light rays, magnetic fields and conveyor belt surface impurities can be avoided; and high detection accuracy is achieved.

Description

technical field [0001] The invention relates to a detection method of a conveyor belt, in particular to a mechanical touch type conveyor belt tear detection method. Background technique [0002] The transportation of coal mines is an important issue in coal mining. As a continuous transportation machine, the belt conveyor is characterized by its continuous operation, large transportation capacity, low power consumption, stable operation, small crushing of materials, and easy automatic control. Widely used in coal transportation. However, due to the particularity of the coal mine business, especially the poor underground transportation conditions, the cost of the conveyor belt accounts for as much as 45% of the cost of the whole machine. Once the belt is torn, the conveyor belt worth hundreds of thousands or even millions will be destroyed in a few minutes. It will be severely damaged and bring great direct and indirect economic losses. The research on the detection device f...

Problems solved by technology

However, due to the particularity of the coal mine business, especially the poor underground transportation conditions, the cost of the conveyor belt accounts for as much as 45% of the cost of the whole machine. Once the belt is torn, the conveyor belt worth hundreds of thousands or even millions will be destroyed in a few minutes. It will be severely damaged and bring great direct and indirect economic losses. The research on the detection device for longitudinal tearing of mining conveyor belts is extremely important.

[0003] At present, conveyor belt tear detection equipment is generally developed based on laser ranging or machine vision technology. The detection process of such detection equipment is cumbersome and unreliable, and has radiation hazards to the human body.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
