Abstract：Considering that current belt replacing method is inefficient, of high safety risk and requires long time, in this paper, we propose continuous belt replacing device, based on electromechanical liquid system. The drive source is hydraulically driven, and the transmission belt mechanism uses a three-stage crawler chassis. In addition, the structure and working principle of the device are expounded, the hydraulic system is simulated, and the performance parameters of pulling the belt and clamping circuit are acquired. The further experimental study of the belt replacing device is carried out to reflect correctness of the simulation. The results show that, the clamping force provided by the clamping circuit is sufficient to allow tracked chassis to clamp the belt. The pressure of the pulling belt system varies with the belt weight, and the speed of the belt replacing varies with the pump displacement. Meanwhile, replacing time is decreased from 5 days(or even more)to 3 days. In summary, the safety and efficiency of the continuous belt replacing device driving by crawler drag are demonstrated.
