Problems solved by technology
[0006] In view of the above situation, the industry should leave the bending space required for the cables as much as possible when the three machines are matched to reduce the amount of interference. Put it in the pedestrian passage, and move the cable (clamp) back into the cable trough after the coal shearer completes the oblique cutting. In fact, this method does not fundamentally solve the problem of cable bending, and there are serious safety hazards; The set tow cable device can be increased according to 2-3 steps, and fixed after heightening according to a certain size, but it will affect the mining height of the coal seam or the clearance of the machine, so it is difficult to be practically applied; in short, the problem of cable bending has seriously affected the reliability of the shearer The demand for high performance and high-efficiency production also greatly hinders the development of thin coal seam shearer technology

The invention discloses a lifting coal winning machine cable towing device with an auxiliary chain, and the device mainly solves the technical problems of improving the working reliability, the production efficiency and the like. The adopted technical scheme is as follows: the device is provided with a lifting mechanism; one end of the lifting mechanism is fixedly arranged on a coal winning machine body and is overhung; a connecting component is hinged on the overhanging end; and the auxiliary chain and a main chain are respectively hinged on the connecting component. The lifting coal winning machine cable towing device with the auxiliary chain is applicable to towing led-in cables of various thin coal bed or thinner coal bed coal winning machines.
Description
Technical field: [0001] The invention relates to a belt clamping cable device, in particular to a coal shearer towing cable device. Background technique: [0002] During the mining process of the existing thin coal seam shearer, it is usually necessary to carry out oblique cutting and feeding, so that the coal mining machine can only walk in a straight section after cutting into the coal wall. Multiple bends occur, and in the most serious place, the cable forms an "S" bend. At this time, there is serious interference between the cable clamp and the bracket; in the coal mining face, the power cable connected to the shearer is usually placed In the special cable trough provided by the coal machine, as the working face becomes longer and longer, the cable of the shearer is also longer and longer. Due to the cable's own weight and friction, the method of directly dragging the cable by the shearer is no longer suitable. To reduce cable breakage and wear and other factors, coal s...
