Abstract
The utility model relates to a height-adjustable oil cylinder of a coal winning machine on a coal mine working face, is classified as a control unit of the coal winning machine on the coal mine working face, achieves the function for detecting the accurate position of the rocker arm of the coal winning machine, and solves the problem of the conventional coal winning machine that the position of the rocker arm of the coal winning machine cannot be detected accurately due to small design space. Aiming to change the height-adjustable oil cylinder of the original coal winning machine, a displacement sensor is mounted in the piston rod of the height-adjustable oil cylinder. The utility model not only solves the problem that an inclination angle sensor is difficult to be mounted in the rocker arm of the coal winning machine, but also overcomes the protection problem of the displacement sensor, and realizes the mounting manner in which the cylinder tube of the height-adjustable oil cylinder moves in a retractable manner.
