[0002] Belt conveyors for coal mines play a vital role and are important transportation equipment in coal transportation. They have the characteristics of large transportation volume, complex working environment, strong carrying capacity, and long transportation distance. They are widely used in major coal-producing areas in my country. Belt conveyors for coal mines can be used not only in the production and processing of coal, but also in the production and processing of other minerals. In terms of maintenance, belt conveyors for coal mines have the characteristics of low maintenance and relatively simple maintenance, and are also loved by mining production and processing companies. Belt conveyors for mines are an indispensable part of coal production and transportation in mines.

After the belt of the conveyor breaks, the two clamping assemblies 5 are clamped and fixed to the two ends of the belt respectively, and the broken end extends out of the clamping assembly 5 with a certain length of margin, and the upper clamping plate 51 and the lower clamping plate 52 are kept perpendicular to the length direction of the belt, and the irregular broken end of the belt is cut and the joint steel buckle is installed.

[0046] After loosening the connection between the slider seat 12 and the linear guide 11, adjust it to the preset position and then re-fix it. The fixed positions of the two slider seats 12 correspond to each other in the left and right directions. The hoisting mechanism 3 starts to work, and each steel wire rope 2 is pulled out from the box 31 and hung on the corresponding hanging nose of the lower clamping plate 52. After the two clamping assemblies 5 are connected to the hoisting mechanism 3 through the steel wire rope 2, the hoisting mechanism 3 drives the two rollers 32 to rotate, and pulls the two ends of the belt to move towards each other and tighten. After measuring the distance between the two ends of the belt, cut another section of the belt of the same specification according to the measurement results, and install the same joint steel buckle at both ends of the other section of the belt. The two ends of the other section of the belt are connected to the two ends of the original conveyor belt. After the connection is completed, the clamping assembly 5 releases the fixation of the conveyor belt and restores the auxiliary traction device to its initial state. The utility model is also suitable for the operation of replacing a new belt.
