Abstract

The invention relates to a hydraulic adjustable damping supporting roller. A bearing block matched with a connecting stationary shaft 1 and a supporting roller pipe body are welded into a whole; a pump fixed mount is fixed on a connecting stationary shaft I by welding; a liquid pipe fixed mount is fixed at one end of a connecting stationary shaft II; the other end of the supporting roller is welded with a snap ring and the bearing block, and the bearing block is fixed by an end face locking ring; and bearings are arranged in two side bearing blocks and the two side bearing blocks are fixed by a bearing end cover. An oil tank is fixed on the connecting stationary shaft II; the liquid pipe is spiral and is positioned on the outer side of the connecting stationary shaft II; an inlet and an outlet of a positive-displacement pump are connected with the oil tank by the oil pipe; and an air cleaner is arranged on the oil tank. The hydraulic adjustable damping supporting roller solves the problem that a rubber belt slides downward continuously after a conveyer drum is braked, achieves the aim of smooth brake control particularly the accurate brake control of the rubber belt of an inclined belt conveyer, prolongs the service life of the rubber belt, and improves the production efficiency. The hydraulic adjustable damping supporting roller is suitable for various mine inclined belt conveyers and meets the requirements of modern comprehensive mechanical mining.

Description

technical field [0001] The invention relates to a hydraulic damping roller, in particular to a damping brake for the belt after the stop of the inclined belt conveyor, so as to meet the requirements of safe, accurate and reliable conveying of materials. Background technique [0002] Belt conveyors have been widely used in all walks of life due to their characteristics of long distance, large capacity and continuous conveying. In the transportation of materials in the coal industry, the belt conveyor is the most prominent. Among them, the idler roller is the supporting and restraining part of the conveyor belt and materials, which has a direct impact on the control of the operation of the conveyor belt. [0003] Most of the idlers used on the existing domestic and foreign belt conveyors are two-way idlers. When this kind of belt conveyor with two-way rollers is used to transport coal in the inclined roadway of the mine, when the driving roller is braked, the belt belt will ...
