As a professional conveyor pulleys manufacturer,we produce high quality conveyor pulleys.The belt conveyor pulleys in underground mining with double drums drive are common.Through the derivation of the traction distribution of the two rollers under the dual-cylinder common driving mode of the belt conveyor, the influence of the actual diameter deviation of the two driving rollers on the traction ratio is discussed. And in response to the above effects, the double drum co-driven belt conveyor roller wear. Proposed solutions and measures. When the transportation volume of coal is large and the transportation length is long or the inclined transportation is adopted, the conveyor driving device has the dual-roller common driving rigidity and the double roller driving method. The purpose of the rigid connection is to enlarge the traction angle. This method can also use multi-machine mobilization. When the motor fails to work, use the synchronous wheel. One driving roller drives the other driving roller, and it can still work, but its defects are also obvious. Frequently, the roller wear is serious, causing frequent damage to the drum, which seriously affects production.The belt conveyor pulleys wear of a double drum co-driven belt conveyor is often associated with load imbalance caused by changes in the diameter of the two drums. This paper briefly analyzes the causes of this kind of 1 and its solutions and measures from the distribution of the traction force of the two belt conveyor idler rollers. The double-rolling common drive can adjust the traction ratio by wear, but the adjustment is extremely slow, and since the stress in the lateral direction of the tape is not uniform, the tape has a deviation on the drum, so the roller is axially The wear is uneven, making the operation of the conveyor gradually unstable.

The belt conveyor pulleys and belts in contact with the outer bread brazing or with the countersunk rivets riveted layer of high-performance wear-resistant steel plate, strong roller wear resistance, such as BRS high-performance wear-resistant steel plate, its wear-resistant The performance is about 10 times of the manganese steel plate. 2 The steel plate retaining ring is set on the circumference of the roller to reduce the axial movement range of the belt, prevent the belt from running off, and the anti-skid groove is processed on the outer surface of the roller to prevent the conveyor belt from being between the roller and the roller. Relative slip to reduce wear on the drum. The soft start device is connected between the motor and the drum to replace the commonly used reducer connection mode before 3, which is the rigid impact of the belt conveyor when starting and stopping, adding the buffering process, and changing the rigid impact to the flexible punching; 1; The conveyor is in normal operation, and the cargo has a pole drive for hydraulic stepless transmission, which reduces the relative slip between the conveyor belt and the drum, and maintains the tangent speed of the drum and the belt speed of the conveyor belt, thereby greatly reducing the wear speed of the drum. At present, in the Huainan Mine, the new Shangyu Mine No. double drive roller belt conveyor. Adopted, 3 630, type soft drive device, after nearly two years of operation and use, compared with other double roller belt conveyors, the roller wear speed is greatly reduced, and the drum service life is greatly improved. Reduced equipment failure rate and maintenance costs, and achieved significant economic benefits.
