Reversible single-drive hydraulic radial-plunger-type driving roller

Abstract

The invention discloses a reversible single-drive hydraulic radial-plunger-type driving roller. The reversible single-drive hydraulic radial-plunger-type driving roller comprises a roller shaft, an eccentric cylindrical shaft section is arranged on the shaft section of the roller shaft, a checking structure is further arranged on the roller shaft, a hydraulic-drive roller driving device comprisinga hollow piston seat disc, a pushing rod and a piston is arranged at the position, corresponding to the eccentric cylindrical shaft section, of a cylinder body, and the pushing rod is forced throughthe piston by using working pressure oil in a high pressure oil cavity; and an included angle is formed between the reaction force direction of the pushing rod and the moving direction of the piston due to the eccentric arrangement of the eccentric cylindrical shaft section, so that the acting force, acting on the pushing rod, of the working pressure oil through the piston is split into two parts,one part is offset by the reaction force provided by the pushing rod, the other part generates rotating torque on the hollow piston seat disc to achieve continuous rotation of driving of the cylinderbody, an additional driving device mounting space is not needed to be arranged, mounting and maintaining are facilitated, and the reversible single-drive hydraulic radial-plunger-type driving rolleris especially suitable for a high-gas mine or a belt conveyor without arrangement space of a driving device.

Description

technical field [0001] The invention relates to a driving roller for a belt conveyor, in particular to a reversible single-drive hydraulic radial plunger driving roller suitable for belt conveyors in underground mines, on the ground, in ports and wharves, and belongs to the belt conveyor. 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, tension...

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)
