Change gear transmission device for rope laying machine

The invention relates to a change gear transmission device for a rope laying machine. The change gear transmission device mainly comprises a shaft, a lower box, a handle, a guide rod, four pairs of gears with different transmission ratios and a part of connecting bolts. 128 lay pitches can be realized by centralizedly carrying out ratio proportioning and distributing on the gears, so that the production needs of all the lay pitches of a rope laying machine are satisfied. According to the change gear transmission device for the rope laying machine disclosed by the invention, a change gear transmission device is added in front of a lay pitch box in a rope laying machine transmission system, and various lay pitch specifications needed by production are centralized in the change gear transmission device, so that the produced product specifications are increased by 4 times, production in a larger range of the product specifications can be realized, a produced steel wire rope is stable and accurate in the lay pitch, the production efficiency and utilization value of the manufactured steel wire rope are improved, the accuracy is improved by 3 times, the quality stability of products is ensured, and equipment can also be in a good running state. The change gear transmission device for the rope laying machine is convenient to operate, is in time-saving, is rapid and is high in efficiency, so that labor productivity is increased.
