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

Abstract

The invention belongs to the field of mining hydraulic motors, particularly discloses a walking type hydraulic cylinder motor. The hydraulic cylinder motor with equal distributed angles is simple in structure, convenient to operate, high in safety coefficient, long in service life, is capable of effectively reducing the accident rate under a coal mine. The hydraulic cylinder motor comprises a box body, three hydraulic cylinders, a crank shaft, a box body front end component and a control system, wherein an installing plate fixed together with a tractor is arranged at one side of the box body; the hydraulic cylinders are arranged in the box body side by side; the hydraulic cylinders do reciprocating motion to drive the crankshaft to do rotating motion and the crankshaft drives the control system to move; the control system is used for controlling the three hydraulic cylinders to do reciprocating motion so as to drive the crankshaft to do continuous rotating motion; the hydraulic cylinders drives the crankshaft to rotate and can be used as left and right input devices of the tractor and a crane so as to drive the tractor and the crane to move simultaneously.

Description

Technical field [0001] The invention belongs to the field of mining hydraulic motors, and particularly relates to a walking hydraulic cylinder motor, which is mainly used for power input on coal mining machines, scraper conveyors, traction locomotives, cranes, etc. in coal mining faces. Background technique [0002] The coal industry is a pillar industry in my country, and safety in coal mining is the top priority. Because gas often exists in coal mines, the main component of gas is 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, as well as trace amounts. Inert gases such as helium and argon. Under standard conditions, methane to butane exists as a gas, and above pentane is liquid. If it encounters an open flame, it can burn, and a "gas" explosion will occur, directly threatening the lives of miners. In order to reduce and p...
