Horizontal hydraulic cylinder type motor

Abstract

The invention belongs to the field of mining hydraulic motors, and particularly discloses a horizontal hydraulic cylinder type motor. The horizontal hydraulic cylinder type motor aims to achieve the technical purposes that the structure is simple, operation is convenient, safety coefficients are high, service life is long, and the underground coal mine accident rate can be effectively reduced. The horizontal hydraulic cylinder type motor comprises a box, three hydraulic cylinders, a crankshaft, a box front end assembly and a control system. An installing seat board is arranged at the bottom of the box, the hydraulic cylinders are arranged in the box side by side, the ends of pistons of the hydraulic cylinders are connected with the crankshaft through piston end covers, the output end of the crankshaft and the installing seat board are arranged on the same side, the hydraulic cylinders move in a reciprocating mode to drive the crankshaft to rotate, the crankshaft drives the control system to move, the control system controls reciprocating motion of the three hydraulic cylinders to drive the crankshaft to conduct continuous rotational motion, the hydraulic cylinders drive the crankshaft to rotate, the rotating speed is low, torque is large, and the horizontal hydraulic cylinder type motor meets the requirements for use of underground coal mine equipment.

Description

technical field [0001] The invention belongs to the field of mining hydraulic motors, and in particular relates to a horizontal hydraulic cylinder motor, 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 order to...

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
