Mining groove type support roller of two-layer bracket

Abstract

The invention relates to a mining groove type support roller of a two-layer bracket. Support rollers of belt conveyers for coal mines are generally steel support rollers, and have such defects as heavy weight, no corrosion resistance, weak water and dust preventing effect and generation of severe hidden dangers for safe production caused by the spark production in the operation process or the hard matter collision. The mining groove type support roller is provided with a bracket and a roller column fixed on the bracket, wherein the bottom of the bracket is fixed on the base through multiple springs; one roller column is provided, and is fixed between roller column fixed bases arranged at the two ends of the bracket through connecting shafts arranged at two ends; a center shaft is arranged at the center of the roller column; a roller column outer cylinder coats the center shaft; a bearing is arranged between the center shaft and the roller column outer cylinder; the inner wall of the roller column outer cylinder is cylindrical; the middle of the outer wall is cylindrical; two ends are frustum-shaped; and the frustum parts are gradually increased from the center to two sides of the roller column outer cylinder in diameter to form a groove type structure. The mining groove type support roller has the advantages of excellent vibration reducing effect, strong transmission performance and long service life.

Description

technical field [0001] The invention relates to a transmission device for coal mines, in particular to a grooved idler roller for mines with double-layer supports. Background technique [0002] The idler roller is an important part of the belt conveyor. Its function is to support the conveyor belt and the weight of the material. The friction between the conveyor belt and the idler roller drives the idler tube body, the bearing seat, the outer ring of the bearing, and the sealing ring to rotate. Realize the transmission of logistics together with the conveyor belt. Most of the currently used mechanical idlers are steel idlers, especially the idlers for belt conveyors used in coal mines. The two ends of the idlers need to be supported by bearings in the bearing housings. There is a problem that it can be designed and not easy to process, which restricts the adoption of new structures. At the same time, steel rollers also have disadvantages such as heavy weight, no corrosion...

Problems solved by technology

Most of the currently used mechanical idlers are steel idlers, especially the idlers for belt conveyors used in coal mines. The two ends of the idlers need to be supported by bearings in the bearing housings. There is a problem that it can be designed and not easy to process, which restricts the adoption of new structures

At the same time, steel rollers still have shortcomings such as heavy weight, no corrosion resistance, poor waterproof and dustproof effect, and sparks will be generated during operation and when hard objects collide, which will bring major hidden dangers to safety production.
