Reversible dual-drive hydraulic radial plunger type transmission roller

Abstract

The invention discloses a reversible dual-drive hydraulic radial plunger type transmission roller. The transmission roller comprises a roller shaft, the shaft section of the roller shaft are providedwith oil distribution shaft sections which are in left-right symmetry, the roller shaft is also provided with a check structure, and the positions, corresponding to the oil distribution shaft sections, in a roller body are provided with two hydraulic-drive roller driving devices provided with hollow piston base plates, push rods and pistons. Working pressure oil in a high-pressure oil cavity actson the push rods through the pistons, an included angle is formed between the reactive force direction of the push rods and the moving direction of the pistons due to eccentric arrangement of the eccentric cylindrical shaft section, then the action force, acting on the push rods, of the working pressure oil through for the pistons is decomposed into two parts, one part of the action force counteracts the reaction force provided by the push rods, and the other part of the action force generates rotating torque for the hollow piston base plates. The two roller driving devices can ensure the stress balance on the premise of ensuring sufficient driving torque, and the transmission roller is particularly suitable for high-gas mines or belt conveyors with no arrangement space for transmission devices.

Description

technical field [0001] The invention relates to a driving roller for a belt conveyor, in particular to a reversible double-drive hydraulic radial plunger driving roller suitable for belt conveyors in underground mines, on the ground, in ports, etc. The field of conveyor technology. Background technique [0002] Belt conveyors, also known as belt conveyors, are widely used in various industries such as machinery, electronics, tobacco, injection molding, post and telecommunications, printing, and food. Belt conveyors can be divided into heavy belt conveyors such as mining belt conveyors according to their conveying capacity, and light belt conveyors such as those used in electronic plastics, food light industry, chemical and pharmaceutical industries. Belt conveyor is a kind of machinery that is driven by friction to transport materials in a continuous manner. It is mainly composed of frame, conveyor belt, idler roller, roller, tensioning device, transmission device, etc. A ...

AI Technical Summary

Problems solved by technology

This traditional belt conveyor transmission needs to be installed on the side of the drive roller. For heavy-duty belt conveyors such as mine belt conveyors, the huge drive motor and reducer not only need to occupy additional installation space, but also for space The narrow coal mine underground coal transport roadway needs additional excavation of the installation and maintenance space of the transmission device, and it is necessary to ensure the coaxial installation of the reducer output shaft and the transmission drum during the installation process, and the installation and debugging are more complicated; in addition, due to the explosion-proof Particularity, especially for high-gas mines, the driving motors used in traditional mine belt conveyor transmissions must use explosion-proof motors, which not only increases production costs, but also increases maintenance costs for supporting facilities (high-power explosion-proof The use of the motor requires an increase in the voltage level)
