A cable squeeze prevention device for a working face

Abstract

The utility model relates to a device for preventing the cable from being squeezed in a coal mine underground mining face, belonging to the field of mining machinery. Comprises an inner ring, an outerring and a middle small ring; The inner and outer rings are hollow rubber rings, and the middle ring is solid rubber ring. The inner ring is located at the center position, the middle small ring is glued to the outer surface of the inner ring every 40 degrees, and the outer ring is glued on the inner surface of the outer ring and sleeved on the outer surface of the middle small ring; The inner ring and the outer ring are open at a position passing through the two intermediate small rings and the inner ring and the outer ring are open at a position passing through the two intermediate small rings, Width of opening is 1cm, An opening is used to flap the device into a wire, the above device has a simple structure, Low production cost, easy to operate, the utility model can effectively prevent the cable from being squeezed directly, As that device is squeeze, deformation will occur, and the cable is replaced by the device first, thereby effectively prevent the power failure, leakage, insulation reduction, short circuit and other problems aft the cable is squeezed, minimizing the influence on the production, protecting the cable from damage to the maximum extent, and reducing the cablereplacement frequency and the production cost.

Description

technical field [0001] The invention relates to a device for preventing cable wires from being squeezed on an underground mining face of a coal mine, and belongs to the field of mining machinery. Background technique [0002] In coal mines, when the coal shearer is cutting coal, the cables that come with the equipment such as the shearer, front and rear scraper conveyors, and loaders will move with the movement of the equipment. During the movement, the brackets will also move forward and backward. Moving, especially near the terminal frame, there are many and complicated cables. During the moving process of the above-mentioned equipment, the built-in cables are often directly crushed, causing problems such as cable leakage and insulation drop, which affect the normal operation of the equipment. , At the same time, it is time-consuming and labor-intensive to accurately check the squeezed position, so it needs to be solved urgently. Contents of the invention [0003] The p...
