Novel vertical roller-type anti-deviation device employing carrier roller

Abstract

The invention discloses a novel vertical roller-type anti-deviation device employing a carrier roller. The novel vertical roller-type anti-deviation device comprises a rotating shaft-type tapered carrier roller device, a hydraulic power device and a vertical roller device, wherein the rotating shaft-type tapered carrier roller device comprises a left tapered carrier roller, a right tapered carrier roller, a middle cylindrical carrier roller, a carrier roller support frame, a rotating shaft device connected with a belt conveyor support, an angular displacement sensor installed on a rotating shaft; the hydraulic power device comprises a lower-end hydraulic cylinder power part, an upper-end hydraulic cylinder rotating part and a hydraulic push rod with a sliding block; and the vertical roller device comprises a vertical roller support, the rotating shaft and the carrier roller. When a conveyor belt deviates, the rotating shaft-type tapered carrier roller device drives the carrier roller support frame to rotate due to the fact that the diameters of the two ends of the tapered carrier roller are different, and primary deviation correction is achieved; and the lower-end hydraulic cylinder power part in the hydraulic power device controls the push rod to extend and retract, the upper-end hydraulic cylinder rotating part controls the push rod to rotate, and when the angular displacement sensor detects the angle change of the rotating shaft-type tapered carrier roller device, the hydraulic cylinder is controlled to act, so that the vertical roller presses the conveyor belt, and secondary deviation correction is achieved.

Description

technical field [0001] The invention relates to an anti-deviation device for a belt conveyor, in particular to a novel vertical-roller type idler anti-deviation device. Background technique [0002] Belt conveyor is a kind of machinery that is driven by friction to transport materials in a continuous manner. It is a kind of transmission equipment in mining, port, metallurgy and other industries in the field of heavy machinery. It is mainly composed of frame, conveyor belt, idler roller, roller, tensioning device, transmission device and so on. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. [0003] During the working process of the belt conveyor, the conveyor belt often deviates due to the inconsistent tension on both sides of the conveyor belt or the misalignment of the material, which can cause accidents such as tearing of the conveyor belt, parking, and production stoppage. [0004] The c...

Problems solved by technology

[0003] During the working process of the belt conveyor, the conveyor belt often deviates due to the inconsistent tension on both sides of the conveyor belt or the misalignment of the material, which can cause accidents such as tearing of the conveyor belt, parking, and production shutdown.

[0004] The common tapered idler shaft anti-deviation device can play a certain role in anti-deviation, but when the deviation is corrected, there will be sliding friction between the conveyor belt and the idler, which will increase internal friction; the common vertical roller anti-deviation device The vertical roller is fixed, passively makes the conveyor belt return, the efficiency is not high, and it is in contact with the edge of the conveyor belt for a long time, resulting in fluffing of the conveyor belt and accelerated damage
