Belt conveyor deviation is usually refers to the belt conveyor in the operation of the conveyor belt is not in accordance with the central position of the conveyor belt around the normal operation. Analysis of belt conveyor width 800mm lag is to mechanized speedy drivage temporary installation, running in the transmission of power with floating operation in the triple acceptor roller roller and two roller belt conveyor, the rotation of the roller conveyor belt to a resistance and a guiding force, to transport with the frame is straight, the material on the conveyor belt is in the middle position of the roller guiding force uniform, and the direction of belt conveyor is the same, then there is no deviation; and in the actual production of conveyor belt rack can reach an ideal state of the straight, level will with the change of roadway to the conveyor belt, the delivery of the materials is not an ideal state of the uniform, so the conveyor belt at the supporting force and the change at any time, by the power to overcome resistance and guiding force is affected Direct cause of belt deviation.
Roller hanging on the beam is allowed to have a small amount of adjustable space to change the direction of guiding force of roller, line maintenance equipment mechanic is constantly changing the guiding force direction of roller for conveyer belt adjustment.
This not only saves manpower and roller conveyor belt into adjustment is not timely still appear deviation caused by the conveyor belt on the two sides of the shelf material spilled phenomenon, these materials need manpower to clean, thus reducing production efficiency increase the labor intensity, so contrary to the modern mine production concept. The design of the anti deviation roller is the result of the rational use of the guiding force after the qualitative change, to a certain extent, laid the foundation for the integrated transportation system.
