The invention relates to a crawler-type quick-change walking system. The system comprises a bearing vertical frame, a driving shaft, an oil-gas automatic tensioning mechanism, a thrust wheel assembly,and a split type caterpillar band, wherein the driving shaft is arranged on the bearing vertical frame, and a flange plate and a driving wheel are arranged on the driving shaft; the oil-gas automatictensioning mechanism is arranged on the bearing vertical frame, the oil-gas automatic tensioning mechanism includes a bearing support, a high-pressure energy accumulator, a tensioning oil cylinder and a tensioning rocker arm, and a tensioning wheel is arranged on the tensioning rocker arm; the thrust wheel assembly includes a swing shaft, a front herringbone support, a rear herringbone support, adriven thrust shaft and a thrust wheel arranged on the driven thrust shaft; and the split type caterpillar band wraps the driving wheel, the tensioning wheel and the thrust wheel. A caterpillar bandis always kept in a proper tensioning state through the tensioning device, problems of impact and vibration generated in a high-speed running process of a rescue vehicle can be effectively solved, andthe stability performance, operation comfort and safety of the caterpillar band vehicle are improved.
