Mining-use hinged roller-column-type trough-type carrier roller

Abstract

The invention relates to a mining-use hinged roller-column-type trough-type carrier roller. A carrier roller for a belt-type conveyor used in a coal mine is mostly a steel-made carrier roller. The steel-made carrier roller has the defects that the weight is heavy, the corrosion resistance is none, the waterproof and dustproof effect is poor, and great hidden dangers which are caused by sparks generated due to the fact that the steel-made carrier roller is collided with a hard object are brought to the safety production. The mining-use hinged roller-column-type trough-type carrier roller is provided with a support and three roller columns fixed on the support, wherein the three roller columns are connected in a series mode, and are arranged in a trough-way which is high at the two ends and low in the middle. Every two roller columns are hinged to each other through a hinged plate arranged at the ends. The support is composed of a base plate and two roller column fixed seats. The base plate is bent into a three-section flat plate, wherein the three sections are parallel to the roller columns respectively. The outer ends of the roller columns arranged at the two ends are fixed on the roller column fixed seats, and the roller column fixed seats are perpendicular to the roller columns arranged at the two ends respectively. The center of each roller column is a central shaft. Each central shaft is sleeved with a roller column outer cylinder, and a bearing is arranged between each central shaft and the corresponding roller column outer cylinder. Each roller column outer cylinder is of a rubber cylindrical structure. According to the mining-use hinged roller-column-type trough-type carrier roller, the good vibration reduction function is provided, the conveying performance is high, and the service life is long.

Description

technical field [0001] The invention relates to a transmission device for coal mines, in particular to a mine-used articulated roller column-type trough-type idler. 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 corrosio...

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.
