Control System for Equidistributed Angle Hydraulic Cylinder Motor

Abstract

The invention belongs to the field of mining hydraulic motors, particularly discloses a control system for an angle equidistribution hydraulic cylinder type motor, and aims to provide a control system for an angle equidistribution hydraulic cylinder type motor which is simple in structure and high in safety factor, and can automatically control a hydraulic cylinder to conduct reciprocating movement. The adopted technical scheme is that the control system comprises a first kowtow device, a second kowtow device and a third kowtow device which adopt a same structure, wherein the first kowtow device, the second kowtow device and the third kowtow device are arranged side by side on a kowtow seat, and are fixedly connected with a box body front end component through the kowtow seat; control valves are arranged at the front of the first kowtow device, the second kowtow device and the third kowtow device respectively, and are used for controlling reciprocating movement of the hydraulic cylinder. The mechanical control system is very suitable for an underground coal mine; potential safety hazard is not generated as an electrical control system; incidence of underground coal mine accidents can be reduced.

Description

technical field [0001] The invention belongs to the field of mining hydraulic motors, and in particular relates to a control system for hydraulic cylinder motors with equal distribution angles. Background technique [0002] The coal industry is the pillar industry of our country, and the safety in coal mining is the top priority. Because gas often exists underground in coal mines, the main components of gas are alkanes, of which methane accounts for the vast majority, and a small amount of ethane, propane and butane. In addition, it generally contains hydrogen sulfide, carbon dioxide, nitrogen and water vapor, and trace amounts inert gases such as helium and argon. Under standard conditions, methane to butane exists as a gas, and above pentane as a liquid. In case of an open flame, it can burn, and a "gas" explosion occurs, directly threatening the life safety of miners. In order to reduce and prevent the occurrence of hairline explosion accidents, the requirements for th...

Problems solved by technology

Diesel engines need to consume a lot of diesel oil during the working process, and they emit a lot of high-temperature hot gas, which poses a safety hazard

[0007] The above coal mine machinery mainly uses traditional motors or diesel engines for power input. This power input method is not suitable for coal mine machinery and equipment, and there will be great safety hazards in the process of using coal mine equipment. The safety factor is high, so the existing power input equipment has seriously restricted the development of coal mine underground equipment
