Description

Belt conveyor for coal mine

Technical Field

Background

The belt conveyor is a continuous action type conveying device which uses a conveying belt as a traction mechanism and a bearing mechanism, has the advantages of long conveying distance, large conveying capacity, continuous conveying and the like, and is currently a key device for coal efficient mining. The belt conveyor has the principle that: the belt is wound by the driving roller and the machine tail reversing roller to form an electrodeless annular belt, and the belt is driven to move by the rotation of the driving roller, so that the purpose of conveying goods on the belt from one place to another place is achieved.

However, when the belt conveyor is in operation, sliding friction occurs between the rollers due to the fact that the belt is lengthened in the long-term use process or friction force between the belt and the rollers is insufficient, so that temperature of related parts such as the belt and the rollers is increased, and even fire disaster occurs when friction is serious, and therefore certain potential safety hazards exist when the whole device is in use. In addition, in the process of conveying coal by using the belt conveyor, coal stacking faults, namely, the condition that the height of the coal on the belt conveyor is larger than that of a normal coal level, are easy to occur. If the coal can not be found and stopped in time, the coal can quickly submerge the head of the conveyor, seriously damage equipment and even endanger personnel safety.

Therefore, a new device is required to be designed to solve the above problems.
