The invention provides a caterpillar band tensioning device for a track vehicle. The caterpillar band tensioning device comprises a crawler wheel frame and an elastic bearing mechanism, wherein the crawler wheel frame and a crawler wheel shaft of a crawler wheel are fixedly arranged, and the elastic bearing mechanism is used for providing elastic bearing force for the crawler wheel frame. The elastic bearing mechanism of the caterpillar band tensioning device comprises a spring force bearing mechanism and a hydraulic pressure bearing mechanism which are connected in series. The spring force bearing mechanism comprises a hollow spring and a guiding sleeve surrounding the hollow spring and guiding stretching and retracting of the hollow spring. The caterpillar band tensioning device for the track vehicle can ensure tensioning of a caterpillar band even under the situation that a hydraulic cylinder leaks liquid or breaks down, and the normal running of the track vehicle with the caterpillar band tensioning device is guaranteed. The dismounting and mounting procedures of the caterpillar band tensioning device are simplified through the guiding sleeve on the periphery of the hollow spring. The invention further relates to the track vehicle with the caterpillar band tensioning device.
