Abstract

The invention relates to a main cable dragging device for a coal mining machine, and belongs to the technical field of coal mining machinery equipment. The device comprises a connecting bracket, wherein the connecting bracket is hinged to one end of a towrope frame; the other end of the towrope frame is hinged to a lifting lug; the lower part of the lifting lug is hinged to a plurality of connecting blocks which are rotatably connected to each other; a Haff slip is arranged between any two connecting blocks in a vertical direction; the connecting block at the lowermost end in the vertical direction is hinged to a connecting frame; and the extending direction of connecting grooves of the connecting blocks is perpendicular to the length direction of the towrope frame. The towrope frame and the connecting bracket are rotatably connected through a screw and a nut. The main cable dragging device is reasonable in structure, capable of freely turning forwards, backwards, upwards and downwardsin use, firm in fixation, safe and practical; the towrope frame is capable of freely adjusting the working state up and down; and the slip and the connecting frame can swing and turn left and right around the towrope frame, the use is convenient, and the strength is reliable.

Description

technical field [0001] The invention belongs to the technical field of coal mining machinery and relates to a coal mining machine main cable dragging device. Background technique [0002] The coal shearer is a device that moves back and forth for a long distance with the length of the working face. The main cable for power supply must be dragged and folded back with the movement of the main engine. Slip off and off-line, affecting safe production. Contents of the invention [0003] Aiming at the above problems, the present invention provides a main cable dragging device of a coal shearer, which can be turned up and down freely, and the cable is fixed securely, safely and practically. [0004] According to the technical solution of the present invention: a main cable dragging device for a coal mining machine, it is characterized in that: it includes a connecting bracket, one end of the connecting bracket is hinged to the cable frame, the other end of the cable frame is hin...
