Change gear transmission device for cabling machine

The utility model provides a change gear transmission device for a cabling machine. The device comprises shafts, a lower tank, a handle, a guide rod, four pairs of gears with different transmission ratios and partial attachment bolts. The gears are subjected to proportion and distribution of ratios in a centralized manner, so that 128 kinds of lay lengths can be realized, and the production requirement for all lay lengths of the cabling machine can be met. According to the change gear transmission device, a change gear transmission device is added before a lay length tank in a transmission system of the cabling machine, and various lay length specifications required by production can be integrated in the change gear transmission device, so that the product specifications are four times more than the existing specifications, and large-scale production of product specifications can be realized; and the produced steel wire ropes are stable and accurate in lay length, so that the production efficiency for manufacturing steel wire ropes and value in use can be improved, the accuracy is 3 times higher than before, the stability of product quality is guaranteed, and the equipment can be in an excellent operation state. The change gear transmission device is convenient to operate, time-saving, quick and efficient, so that the labor productivity is improved.
