The invention provides a crawler belt tensioning device and a crawler belt type advancing device. The caterpillar belt tensioning device is used for a caterpillar belt and comprises the caterpillar belt , a fixing shaft, two or more pressing plates, two or more rotating arms and an elastic piece. The supporting seat for pressing the caterpillar belt is divided into four surfaces, so that the contact is more uniform, and the contact area of the caterpillar belt and a slope plane can be increased when the caterpillar belt is kept tensioned, so that the friction force is increased to prevent slipping; and furthermore an avoiding structure is arranged at the middle part of the supporting base; when the caterpillar belt crosses the protruding obstacles, the front end of the supporting base tilts, but the rear end of the supporting base keeps pressing the caterpillar belt, then the protruding obstacles are contained in the receding structure so that all the lower surfaces of the supporting base can press the caterpillar band, and finally the rear end of the supporting base tilts, but the front end of the supporting base keeps pressing the caterpillar belt. The contact area and adhesive force between the crawler belt and a slope plane are increased, the operation stability of the crawler belt is improved, and enough friction force is kept to achieve normal walking.

    本发明提供一种履带张紧装置及履带式行进装置。履带张紧装置用于一履带,包括履带、固定轴、两个以上压板、两个以上转动臂以及弹性件。本发明通过将压紧履带的支撑座分为4个面,使其接触更均匀,在履带保持张紧时能增加履带与斜坡平面的接触面积,从而加大摩擦力防止打滑;并进一步在支撑座中部设置避位结构,当履带跨越凸起障碍物时,首先支撑座的前端翘起但后端保持压紧履带,其次凸起障碍物容置于避位结构中而使得支撑座所有下表面压紧履带,最后支撑座的后端翘起但前端保持压紧履带,增大了履带与斜坡平面的接触面积及附着力,提高履带运行的稳定性,保持足够的摩擦力实现正常行走。
