Continuous transport belt conveyor to transfer a major mechanical equipment industry is very wide, as well as the prevalence of some problems, these problems affect the equipment operating life of equipment efficiency and even pose a security risk. For example, the belt deviation the belt deviation belt side cause accelerated wear, and even cause the belt breaks, how to solve the problem \This thesis is a study conducted for the the deviation phenomenon and the belt conveyor during operation. This paper begins with a brief analysis of the the deviation phenomenon exists in the belt conveyor, deviation reasons and deviation caused by the impact, followed by an overview of the development of an overview of belt conveyors and belt conveyor at home and abroad, and analytic comparison of domestic and foreign The gap on the technical performance of the belt conveyor. From multiple angles and then a more detailed analysis of the reasons for the deviation occurs belt. The belt deviation of a variety of reasons, but the most fundamental reason is that between the drive roller and tension roller belt tension uneven on both sides, making the belt on both sides of the cylinder pressure is inconsistent. Deviation reason this paper, some improvement measures and methods, and last, respectively, from small belt conveyor and a large belt conveyor to proceed with corrective analysis. Small belt conveyor carrying small, short transport distance corrective method is relatively simple, mainly from the point of view of mechanics on corrective analysis. For example, the design of the drum-shaped rollers, the drum on the belt to maintain a certain degree of automatic performance; rollers mounted on both sides slope follower formula baffle obvious force, these methods can be effectively prevented a small belt conveyor, can be generated on the belt on the belt \Large belt conveyor load and long distance transport, and run fast, corrective method is more complex and difficult, mainly electronic corrective. This article by installing variable frequency motor side of the drive roller to change the motor speed to control the speed of the drive roller, so as to achieve the automatic correction. By taking these measures, it is good to play a role in prevention corrective belt deviation more effectively improve the work efficiency of the belt conveyor, and at the same time to ensure the safe operation of the belt conveyor.
