The invention discloses a displacement detection device for a traveling mechanism of a coal-winning machine. An executing element of the traveling mechanism of the coal-winning machine is a traveling wheel (1) on which a traveling transmission device (2) is arranged; the displacement detection device (3) is arranged at the tail end of the traveling transmission device (2); the displacement detection device (3) consists of a mechanical transmission device (4), an electronic rotary counter (5) and an electronic displacement controller (6); the mechanical transmission device (4) is arranged on the traveling transmission device (2); and the mechanical transmission device (4) is connected with the electronic displacement controller (6) through the electronic rotary counter (5). By adoption of the displacement detection device, the position of the coal-winning machine can be detected accurately; proper working parameters are set in the electronic displacement controller of a coal-winning machine control system according to working conditions at different positions, so faults of complicated working sections and a machine head and a machine tail of a transporter can be avoided; and automated control of a coal-winning machine is realized.
Description
technical field [0001] The invention relates to a displacement detection device, in particular to a displacement detection device for a coal mining machine traveling mechanism. Background technique [0002] Shearer is the core equipment of mechanized coal mining in coal mines. It is used in conjunction with transportation equipment and support equipment to achieve efficient coal mining in roadways. The traveling mechanism is an important walking executive component in the shearer, and the displacement of the traveling mechanism on the conveyor determines the position of the shearer on the working face. When the coal shearer is working, due to the complex coal seam of the working face and the different conditions of each section, it is easy to break down when cutting under the same working condition, and it is difficult to determine the position of the nose and tail of the transporter by manual operation, which often occurs Faults such as incomplete cutting and coal shearer ...
