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

Embodiment Construction
[0031] Such as figure 1 — image 3 As shown, the equal distribution angle hydraulic cylinder motor includes a box body 1, three hydraulic cylinders 2, a crankshaft 3, a front end assembly of the box body 4, and a control system 5. The box body 1 is a shell structure as a whole, and the inside of the box body 1 Three earrings 11 for installing the hydraulic cylinder 2 are arranged side by side at the rear end of the box. The earrings 11 are provided with a hydraulic cylinder installation hole 12. The front end of the box body 1 is provided with a box semicircular seat 13 for installing the crankshaft 3. The box The body semicircular seat 13 is provided with a threaded hole connected with the box front end assembly 4; The internal hydraulic cylinder installation hole 12 is fixedly connected, and the hydraulic cylinder piston end 22 is connected to the crankshaft 3 through the piston end cover 23. The reciprocating motion of the hydraulic cylinder 2 drives the crankshaft 3 to ro...

The invention belongs to the field of mining hydraulic motors and particularly discloses a crankshaft for a hydraulic cylinder motor with equal distributed angles. The crankshaft for the hydraulic cylinder motor with the equal distributed angles is simple in structure, high in safety coefficient and long in service life, and is capable of converting the linear motion of a hydraulic cylinder to rotating motion. The crankshaft comprises a middle shaft, an output shaft, a tail shaft and first, second and third piston crank connecting devices which are arranged side by side, wherein the second piston crank connecting device is in interference fit with a shaft installing hole in a plywood through the middle shaft, and is fixedly connected with the first and third piston crank connecting device respectively; crank pins of the first, second and third piston crank connecting devices are in 120-degree uniform distribution with the shaft installing hole as the center; the output shaft is fixedly connected with an shaft installing hole in the plywood at the outer side of the first piston crank connecting device and the tail shaft is fixedly connected with a shaft installing hole in the plywood at the outer side of the third piston crank connecting device.
Description
technical field [0001] The invention belongs to the field of mining hydraulic motors, in particular to a crankshaft for an equal distribution angle hydraulic cylinder motor. 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 the safety factor of d...
