Conveyor belt wear repair treatment structure and repair treatment method

Abstract

The invention discloses a conveyor belt wear repair treatment structure and a repair treatment method. The repair treatment structure is a layered structure, and comprises an outer protective film layer, an ultra-high molecular weight polyethylene outer layer and an ethylene-propylene-diene monomer bottom layer from outside to inside in sequence. The repair treatment method adopts a local cold repairing mode, and comprises the following steps: a, cleaning and drying the position and the periphery to be repaired of a conveyor belt; b, cutting off surface rubber at a damaged position along the edge of the damaged position of the conveyor belt; c, roughening the cut edge, and cleaning; d, accurately cutting a repairing material according to the cutting size and thickness, roughening, and cleaning; and e, coating the surface required to be repaired of the conveyor belt and the bottom surface of the ethylene-propylene-diene monomer bottom layer of the repairing material with a cold repairing adhesive, and fitting and compacting the surface required to be repaired of the conveyor belt and the bottom surface of the ethylene-propylene-diene monomer bottom layer of the repairing material. According to the conveyor belt wear repair treatment structure and the repair treatment method, the problems, such as wear, scratches, breakage, overlapped part cracking and the like, of the conveyor belt can be effectively solved; and the conveyor belt wear repair treatment structure and the repair treatment method has the characteristic of quick repair on site.

Description

technical field [0001] The invention relates to the field of conveyor belt wear repair, in particular to a conveyor belt wear repair treatment structure and a repair treatment method. Background technique [0002] With the development of the coal industry, the use of conveyor belts in coal mines in my country is also increasing. As the main equipment for transporting materials in the mining field, the service life of the belt conveyor is very important. However, in actual use, since the conveyor belt is a standard elastic device and is the most important part of the conveyor, the life of the belt conveyor mostly depends on the life of the conveyor belt. The cost of the conveyor belt accounts for 30% to 50% of the cost of the belt conveyor. Due to the long-distance uninterrupted transportation of a large amount of coal and its sundries, the belt conveyor will cause fatigue to a large extent on the conveyor belt. Once this fatigue phenomenon is not fundamentally resolved, th...

[0003] The wear problem of the conveyor belt not only accelerates the damage of the conveyor belt, but also causes material leakage and waste

Usually, after the problem of conveyor belt equipment occurs, the enterprise uses frequent sewing, heating vulcanization, or scrapping and updating. These methods cannot solve practical problems well. Thermal vulcanization requires a lot of manpower and material resources, and the construction time is also very time-consuming. long, and scrapping and updating have caused an increase in equipment procurement costs
