The invention belongs to the technical field of coal mine mobile platforms. The crawler belt traveling mechanism with the variable driven wheels and the variable supporting wheels comprises a crawler belt, a driving wheel, the driven wheels, the supporting wheels and a mounting frame. A first rotating mechanism is arranged on the mounting frame, and the supporting wheel is rotationally connected with the mounting frame through the first rotating mechanism; the first rotating mechanism comprises a rotating arm and a driving device; a rotating fulcrum is arranged in the middle of the rotating arm, and the rotating arm and the mounting frame rotate through the rotating fulcrum; one end of the rotating arm is rotationally connected with the supporting wheel, and the other end of the rotating arm is connected with the driving device; the driving device drives the rotating arm to rotate around the rotating fulcrum and drives the supporting wheel to move, and therefore the supporting height of the supporting wheel is adjusted. According to the crawler belt traveling mechanism, the supporting wheels and the driven wheels can be adjusted, so that the supporting height of the crawler belt is changed, and the height of a vehicle body is adjusted.

    本发明属于煤矿移动平台技术领域。涉及一种从动轮与支撑轮可变的履带行驶机构,包括履带、主动轮、从动轮、支撑轮、安装架;所述安装架上设有第一转动机构,所述支撑轮通过所述第一转动机构与安装架转动连接;所述第一转动机构包括转动臂、驱动装置;所述转动臂的中部设有转动支点,并通过所述转动支点与安装架转动;所述转动臂一端与所述支撑轮转动连接,另一端与所述驱动装置连接;所述驱动装置驱动转动臂绕转动支点转动,并带动支撑轮移动,从而调整支撑轮的支撑高度。本发明中的履带行驶机构,支撑轮与从动轮均可进行调整,从而改变履带的支撑高度,实现车身高度的调整。
