Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific examples.

[0013] A method for repairing long-distance longitudinal tearing of a steel cord belt. According to the belt repair effect and the length of time required for repair, the damaged part of the belt is the coal transportation surface, and the repair is divided into the following two schemes:

[0014] (1) if figure 1 As shown, if you want to have a good repair effect, use one-sided permanent repair, which takes a long time: use polyurethane material as the repair strip, first cut the torn belt into a V-shaped groove with a width of 2 cm from the torn part of the belt, and then use The hot-filling material is heated by a glue gun and flows into the V-shaped groove for caulking; when the non-coal surface is running to the lower belt position, it is bonded with a repair strip. After the bonding is completed, the belt is permanently bonded. Purpose, it is required to be equal to or l...

Abstract

The invention discloses a long-distance longitudinal tearing repairing method for a steel wire rope core adhesive tape. According to the belt repairing effect and the time length required by repairing, repairing is divided into the following two schemes that (1) single-face permanent repairing is adopted, specifically, a polyurethane manufacturing material is used as a repairing strip, a torn beltis firstly formed into a V-shaped groove with the width being 2cm from the belt tearing part, then a hot repairing filling material is heated through a glue gun and then flows into the V-shaped groove, and joint filling is conducted; and when a non-coal-conveying face is transferred to the lower belt position, the repairing strip is used for bonding, after bonding is completed, the purpose of belt permanent bonding is achieved, the requirement is equal to or lower than the belt surface, then a belt conveyor operates normally, the consumed time is long, and the effect is good; and (2) the twofaces of the belt are bonded through the repairing strip, the polyurethane manufacturing material is used as the repairing strip, the non-coal-conveying face of the torn belt is firstly transferred tothe return lower belt position and bonded through the repairing strip, then the damaged belt coal conveying face is transferred to the top plate face, and then the upper repairing strip is bonded. The consumed time is short, and the production benefits are good.

Description

technical field [0001] The invention relates to the field of belt repair, in particular to a method for repairing long-distance longitudinal tearing of a steel cord core belt. Background technique [0002] In the process of coal mine production, the belt is easily damaged by foreign objects, such as wear after the idler roller is stuck, the impact of large materials, scratches caused by metal foreign objects mixed in, and scrap iron on the iron remover causes the belt to deviate and tear. After the long-distance longitudinal tear of the belt occurs, it is very important for the mine coal transportation system to quickly restore the coal transportation system of the mine, reduce the expenditure caused by belt rescue accidents, and greatly reduce the labor intensity of workers. There are two main types of traditional long-distance longitudinal tear repair techniques for steel wire rope tapes: (1) Replace all damaged belts: If the long-distance tear damage of the belt is to be ...
