A kind of belt conveyor belt replacement method

Abstract

The invention discloses a belt conveyor belt replacement method. The belt replacement vehicle used for continuously and synchronously retracting and unwinding belts includes an upper crawler part, a middle crawler part, a lower crawler part and a centralized electric control part; the belt replacement method specifically includes Steps such as equipment transition, tape change preparation, new tape input positioning, old tape input positioning, tape replacement, etc. The invention can flexibly adjust the working position according to the specific working conditions of the construction site, can realize the complete matching of the speed of unwinding the new tape and the take-up of the old tape, and realizes the automatic balance between the pulling force of the recycled tape and the resistance of releasing the new tape during the tape replacement process, and synchronization , higher stability and safety; the continuous wavy track surface concave-convex snap fit with the clamping tape method does not damage the tape, but also ensures a stable clamping, and can be replaced by multiple tapes that can continuously and synchronously retract and release the tape The combined use of vehicles in series is especially suitable for belt replacement of ultra-long-distance belt conveyors.

Description

technical field [0001] The invention relates to a belt replacement method, in particular to a method suitable for replacing belts of large belt conveyors used in coal mines, docks and other places, and belongs to the technical field of belt conveyor maintenance equipment. Background technique [0002] Belt conveyor, also known as belt conveyor or belt conveyor, is a machine that transports materials in a friction-driven continuous manner, mainly including racks, conveyor belts, rollers, rollers, tensioning devices, transmission devices, etc. It can It forms a material conveying process from the initial feeding point to the final unloading point on a certain conveying line, which is widely used in metallurgy, mining, electric power, chemical industry and other industries. [0003] Belt conveyor plays an irreplaceable role in coal mine production because of its advantages of large conveying capacity, simple structure, low cost and strong versatility. It is the main equipment t...

Problems solved by technology

[0005] 1. In order to achieve stable traction, it is necessary to set up an additional positioning and installation location for the tape replacement device in the mine. However, the working environment of the coal mine is complex, especially for mines with a distance of more than 1,000 meters. The transportation, positioning and installation of the tape replacement device are relatively difficult;

[0006] 2. For ultra-long-distance belt conveyors, if the power of the belt replacement device does not match, it often results in insufficient clamping force for clamping the belt or insufficient traction for pulling the belt, which in turn causes the belt to slip or cannot be pulled. Therefore, it is necessary to Cooperating with a sufficiently high-power tape replacement device will virtually increase the volume and weight of the tape replacement device, making transportation, positioning and installation more difficult;

[0007] 3. In order to facilitate transportation and positioning and installation, the tape replacement device for conveying the new tape and the tape replacement device for recycling the old tape are usually set up separately, positioned and installed separately, which will easily lead to a mismatch between the new tape unwinding and the old tape take-up speed If the situation arises, it will easily lead to poor laying quality of the new conveyor belt or increased belt change time
