[WANG, Zhenqian, HU, Jing, HU, Tao, ZHOU, Changfei, DONG, Chao, SONG, Zhen, LIU, Kunmin, ZHANG, Liqiang, GU, Enyang, DING, Haichun, HE, Lining, MU, Jie] R&D/Dai Guo No. 168, Huancheng East Road Fengxian District, Shanghai 201401, CN The invention relates to an automatic towing cable system of a coal mining machine. The space in a cable trough is divided into three layers, namely an upper layer, a middle layer and a lower layer, by a dividing plate assembly; lower parts of a towing cable trolley and a constraint cage towing rope device are limited in the middle layer and can only slide in the length direction of the cable trough back and forth; the constraint cage towing rope device is fixed relative to the coal mining machine; a steel wire rope goes through the cable trough in the length direction; one end of the steel wire rope bypasses a fixed pulley at a head-gate end of the cable trough of an AFC (armoured-face conveyor) to change the direction and then is connected with the lower part of the constraint cage towing rope device, and the other end bypasses a fixed pulley at a tail-gate end of the cable trough to change the direction, then bypasses a movable pulley of the towing cable trolley to change the direction again, and returns to the tail-gate end of the cable trough to be fixed; a cable clamp set with one end fixed to the head-gate end of the cable trough extends from the head-gate end of the cable trough to the tail-gate end in the upper layer of the cable trough in the length direction: the cable clamp set firstly goes through the constraint cage of the constraint cage towing rope device and then reaches the location of the towing cable trolley. There the cable clamp set bypasses the roller of the towing cable trolley to change the direction and then extends to a coal mining machine and at last is fixed to the coal mining machine; the head gate and the tail gate which the automatic towing cable system concerned are interchangeable for general layout of the invented system. The invented automatic towing cable system of the coal mining machine has following great advantages: it can guide itself in the cable trough of AFC while the coal mining machine haulages, needs no external input power, the cable clamp set concerned will not fall off from the cable trough any more and the steel wire rope concerned will be prevented from escaping out of the cable trough. Thereby the invented automatic towing cable system is very safe during utilization.＜img id="iaf01" file="imgaf001.tif" wi="74" he="233" img-content="drawing" img-format="tif" /＞
