Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, in particular to an anti-deviating device suitable for coal mine belt conveyors. Background Art

[0002] Coal mine belt conveyor is a kind of equipment widely used in the process of coal mining and transportation. It is mainly used to transport coal from the coal mining face or other loading points to the designated unloading point. Its characteristics are that the belt conveyor can realize large-scale and long-distance material transportation, and the transportation volume per hour can reach tens of tons or even thousands of tons.

[0003] In the past, the anti-deviation device of the belt conveyor was constructed by placing a support bracket under the anti-deviation device and using vertical rollers on both sides to control the position of the anti-deviation device. When the belt was running, the anti-deviation device moved freely with the belt, and the belt deviation device could not play its due role. Belt deviation accidents occurred frequently. In order to fix the position of the anti-deviation device, ropes and lead wires were often used to tie the anti-deviation device to the belt truss to prevent the deviation device from swinging back and forth. This was not only unsightly, but also the angle of the anti-deviation device could not be adjusted at any time, and could not meet the requirement of adjusting the belt running angle at any time.

[0004] The existing anti-deviation device for belt conveyors at this stage is composed of a support bracket placed under the equipment and the vertical rollers of the anti-deviation device to control the position of the anti-deviation device. However, the vertical anti-deviation device is prone to uneven force depending on the size of the load, so that excessively large and heavy loads will affect the wear of the crawler belt and reduce the service life of the crawler belt. Therefore, we have proposed a device that is widely used in coal mining and transportation. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-deviation device suitable for a coal mine belt conveyor, which drives the output rod to rotate through a motor, so that the roller five pulls the crawler belt to rotate, so that the equipment is in operation, and the arrangement of the roller five can ensure that the coal mine is smoothly transported at the crawler belt outlet, and the three rollers at the bottom serve as support for the bottom of the crawler belt, so that after the crawler belt is transported, the friction between the crawler belt and the cross plate is reduced, thereby extending the service life of the crawler belt, solving the problem of the existing anti-deviation device for belt conveyors at this stage, which is composed of placing a support bracket under the equipment and using the vertical rollers of the anti-deviation device to control the position of the anti-deviation device, but the vertical anti-deviation device is prone to uneven force according to the size of the load, so that too large and heavy loads will affect the wear of the crawler belt, reduce the service life of the crawler belt, and then fail to fully play the corresponding role.
