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

Abstract

The invention discloses a traction system and method for quickly replacing flexible belts of a long-distance elevated belt conveyor. Juzhong direction-changing traction system includes horizontal support anti-deflection roller group, Juzhong direction-changing roller group, secondary direction-changing support roller group, traction loader, traction wire rope at the pull-out end and traction wire rope at the pull-in end. According to the site space requirements, when the conveyor belt is replaced, the high-efficiency convergent rolling and direction-changing traction in the range of 0‑180° to the left or right can be realized, so as to safely, reliably and efficiently complete the convergent transformation of the conveyor belt of the long-distance elevated belt conveyor Work toward traction. The traction system makes full use of the characteristics of the center-converting traction device, and the efficiency is more than 5 times higher than that of the original large-scale crane hoisting traction method, which effectively overcomes the limitation of the traction space on the site, and significantly shortens the time spent on the belt conveyor due to the long-term traction of the conveyor belt. The impact of belt replacement and maintenance time can greatly improve the replacement efficiency of flexible conveyor belts for long-distance elevated belt conveyors.

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...

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
