Description

Technical Field

[0001] The present invention relates to the technical field of roller rubber lagging wear detection, and in particular to a self-powered belt conveyor roller rubber lagging wear detection system and method. Background Art

[0002] Belt conveyors are widely used in coal mining, metallurgy, construction and other industries due to their long conveying distance, large transportation volume, high adaptability and strong versatility. The rubber-coated roller is composed of a metal roller and a rubber-coated layer on its outer surface, and is an important component of the belt conveyor. The rubber-coated layer has the functions of protecting the metal roller from wear, preventing the belt conveyor belt from slipping, and reducing belt wear, thus providing guarantee for the efficient operation of the belt conveyor. In the actual working process, the rubber-coated layer will gradually wear out, and when it wears to a certain extent, the roller needs to be replaced and re-coated. However, due to factors such as the environment, operation, and worker proficiency, the visual inspection method often cannot observe and evaluate the wear of the rubber-coated layer in time, and it cannot be replaced in time, resulting in direct contact between the metal roller and the belt, resulting in irreversible wear, and even causing the belt conveyor belt to slip or tear, causing safety accidents. Therefore, in order to ensure the safety of production, it is necessary to study and optimize the wear detection technology of the rubber-coated roller.

[0056] S1. When the rubber-coated drum wheel shell 7 rotates, the sun gear 1-1 connected to it rotates coaxially therewith, and the sun gear 1-1 drives the planetary gear 1-2 to rotate through the bearing 1-3.

[0058] S3. At the same time, the energy management device 3 analyzes the main control chip 3-2. When the output of the self-power supply device 1 is redundant, the energy management device 3 stores the instantaneous redundant energy in the rechargeable battery 3-3. When the output of the self-power supply device 1 based on the planetary gear system cannot meet the energy requirements, the battery energy is called to power the rubber lagging wear quantitative detection device 5.

[0059] S4. When the rubber bag is worn to a certain extent, the qualitative detection wire 6-1 in the wear qualitative detection device 6 will be worn off, causing the overall current in the circuit to decrease, thereby completing the qualitative detection. The current is converted into a voltage output through the sampling resistor 5-2 in the rubber bag wear quantitative detection device 5, and converted into a digital signal through the AD converter 5-3. Finally, the voltage information is wirelessly sent to the host computer through the communication chip 5-4.
