Traction system and method for rapid replacement of flexible belt of long-distance overhead belt conveyor

Abstract

The invention discloses a traction system and method for rapid replacement of a flexible belt of a long-distance overhead belt conveyor. A centering steering traction system comprises a horizontal supporting anti-deviation carrier roller set, a centering steering carrier roller set, a secondary steering supporting carrier roller set, a traction loader, a traction-out end traction steel wire rope and a traction-in end traction steel wire rope. According to the site space requirement, when the conveying belt is replaced, efficient centering rolling steering traction within the range of 0-180 degrees leftwards or rightwards is achieved, and therefore centering steering traction work of the conveying belt of the long-distance overhead belt conveyor is safely, reliably and efficiently completed. The traction system fully utilizes the characteristics of a centering steering traction device, the efficiency is improved by more than five times compared with an original large crane hoisting traction mode, the site traction space limitation is effectively overcome, the influence of too long traction time of the conveying belt on the replacement and maintenance time of the conveying belt of the belt conveyor is remarkably shortened, and the replacement efficiency of the flexible conveying belt of the long-distance overhead belt conveyor is greatly improved.

Description

technical field [0001] The invention relates to the technical field of flexible belt conveyors, in particular to a centering and direction-changing traction system and a traction method for replacing flexible conveyor belts of long-distance elevated belt conveyors. Background technique [0002] During the long-term use of the belt (conveyor belt) of the belt conveyor, there are sudden abnormal scratches or tears on the belt surface of the conveyor belt, or due to the wear of the rubber on the working surface of the conveyor belt to a certain extent, even the wire rope appears Corrosion and cracks make it impossible to use normally. Therefore, in order to ensure the safe and stable operation of the conveyor belt, it must be replaced regularly. [0003] When the belt conveyor operation line replaces the conveyor belt, the conveyor belt traction method generally adopted varies with the parameters such as the layout of the conveyor frame, the space size of the traction site, th...

AI Technical Summary

Problems solved by technology

The main problems are as follows: 1. Due to the limitations of high-altitude operations, site and hoisting space, height, and lifting capacity, the large-tonnage belt cannot be lifted to a high position, so the belt can only be designed in small bundles, and the number of vulcanized joints has increased significantly ; 2. The length of one traction of the crane is limited by the lifting height of the crane, and it can only tow 20 meters at a time, resulting in low traction speed, low safety factor, and significantly prolonged maintenance time, which has a great impact on loading and unloading production

The research object of this case is a long-distance conveyor belt with a total length of 1,500 meters. According to statistics, the original process took 20 hours to complete the traction, which seriously affected the production efficiency of the enterprise.

3. When replacing the conveyor belt in the middle of two or more parallel belt conveyors, it will affect the normal operation of the adjacent belt conveyor, and there are many safety hazards. At least other adjacent belt conveyors that are working will be stopped at the same time, which will seriously affect Unloading production
