Same-distribution-angle hydraulic cylinder motor

Abstract

The invention belongs to the field of mining hydraulic motors, and especially discloses a same-distribution-angle hydraulic cylinder motor. A technical problem to be solved is providing a same-distribution-angle hydraulic cylinder motor with the advantages of simple structure, operation convenience, high safety coefficient, long service life and effective reduction of the coal mine underground accident rate. The motor comprises a case body, three hydraulic cylinders, a crankshaft, a case body front end assembly and a control system, the whole case body is a shell structure, the three hydraulic cylinders are arranged in the case body side by side, the front end of the case body is provided with a case body semicircle seat for installing the crankshaft, the case body front end assembly is fixedly connected with the case body to fix the crankshaft, the piston terminals of the hydraulic cylinders are connected with the crankshaft through piston terminal covers, the hydraulic cylinders move back and forth to drive the crankshaft to rotate, the crankshaft drives the control system to move, and the control system controls the reciprocating motion of the three hydraulic cylinders in order to drive the crankshaft to continuously revolve. The motor adopting the hydraulic cylinders to drive the crankshaft to rotate has the advantages of low rotating speed, large torque, and suitableness for the use requirements of coal mine underground equipment.

Description

technical field [0001] The invention belongs to the field of mining hydraulic motors, in particular to a hydraulic cylinder motor with equal distribution angles, which is mainly used for power input of shearers, scraper conveyors, traction locomotives and cranes in coal mining working faces. 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 ...

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
