Abstract
Description
Technical Field
[0001] The invention belongs to the field of conveyor belt anti-tearing devices, and in particular relates to a novel conveyor belt anti-tearing device. Background Art
[0002] Conveyor belts, also known as transport belts, are composite products of rubber, fiber, metal, or plastic and fabric used in belt conveyors to carry and transport materials. Conveyor belts are widely used in industries such as cement, coking, metallurgy, chemical industry, steel, and mining. However, when the existing technology is used, some of the discharged materials from the mine will be mixed with iron pieces and other debris, resulting in the long iron pieces being stuck between the material delivery pipe and the conveyor belt. Due to the hardness of the long iron pieces, the conveyor belt will be pressed against the conveyor belt after being stuck, resulting in the tearing of the conveyor belt. Traditional conveyor belt tearing detection devices mostly use laser Line irradiation detection or leakage detection, etc., but because the belt will become relatively closed after detaching from the torn part due to its own elasticity and other reasons, laser detection and leakage detection may not be able to detect the tearing in time. Especially when the upper layer of the conveyor belt is curved, it is even more inconvenient for laser monitoring, resulting in poor monitoring accuracy, which leads to long belt tear length or complete tearing. Laser detection is also prone to false alarms due to scratches and other unevenness on the bottom of the conveyor belt, and falling materials are also prone to false alarms due to debris or dust. In addition, the cost and maintenance cost of laser equipment are high, which is relatively inconvenient. Summary of the invention
[0003] 1. Technical issues to be resolved
[0004] In order to overcome the shortcomings of the prior art, a new type of conveyor belt tearing prevention device is proposed to solve the problem that when the prior art is used, part of the discharged materials of the mine will be mixed with iron pieces and other debris, resulting in that when long iron pieces appear, the long iron pieces will be stuck between the blanking pipe and the conveyor belt. Because of the hardness of the long iron pieces, the conveyor belt will be pressed against the conveyor belt after being stuck, resulting in the tearing of the conveyor belt. Traditional conveyor belt tearing prevention detection devices mostly use laser line irradiation detection or leakage detection. However, since the belt will be relatively closed due to its own elasticity after being separated from the torn part, laser detection and leakage detection may not be able to detect the tearing in time. Especially when the upper layer of the conveyor belt is arc-shaped, it is more inconvenient to monitor with laser, resulting in poor monitoring accuracy, which leads to long belt tearing length or complete tearing. Laser detection is also prone to false alarms due to unevenness such as scratches on the bottom of the conveyor belt, and the blanking is also prone to false alarms due to debris or dust.

Due to the hardness of the long iron pieces, the conveyor belt will be pressed against the conveyor belt after being stuck, resulting in the tearing of the conveyor belt. Traditional conveyor belt anti-tear detection devices mostly use laser line irradiation detection or leakage detection. However, since the belt will become relatively closed due to its own elasticity after detaching from the torn part, laser detection and leakage detection may not be able to detect the tearing in time. Especially when the upper layer of the conveyor belt is arc-shaped, it is more inconvenient to monitor with laser, resulting in poor monitoring accuracy, which leads to long belt tear length or complete tearing. Laser detection is also prone to false alarms due to scratches on the bottom of the conveyor belt, and blanking is also prone to false alarms due to debris or dust.
