The invention relates to a crawler belt with adjustable supporting wheel. The crawler belt comprises a driving wheel, a supporting wheel adjusting device, a track shoe, a track frame and fixed supporting wheels. The supporting wheel adjusting device comprises a rotating rod, a moving rod, a fixed rod, a hydraulic cylinder, a connecting pin and the adjustable supporting wheel. The hydraulic cylinder comprises a piston rod and a cylinder barrel. The piston of the hydraulic cylinder stretches out and draws back to drive the movable rod to move along the track of the fixed rod, so that the rotating rod is driven to rotate with the lower connecting pin as the circle center and the length of the rotating rod as the radius, and when the piston stretches to the maximum value, the adjustable supporting wheel moves to the position below the track shoe to be in a working state; and when the piston is retracted, the supporting wheel adjusting device is in a non-working state. The crawler belt has the advantages that the number of fixed supporting wheels on the crawler belt is reduced, and the cost is reduced; the supporting wheel adjusting device is convenient to mount and dismount, so that the maintenance cost and the maintenance difficulty are reduced; the number of the supporting wheels can be adjusted according to actual ground conditions, so that driving is more convenient.

    本发明涉及一种支撑轮可调节式履带。包括驱动轮、支撑轮调节装置、履带板、履带架、固定支撑轮。支撑轮调节装置包括旋转杆、移动杆、固定杆、液压缸、连接销、可调节支撑轮。液压缸包括活塞杆、缸筒。通过液压缸活塞伸缩带动移动杆沿固定杆的轨道进行移动,从而带动旋转杆以下方连接销为圆心,以自身长度为半径发生旋转,当活塞伸长到最大值时,可调节支撑轮移动到履带板下方处于工作状态,当活塞收回时,支撑轮调节装置处于非工作状态。本发明的优点在于,减少了履带上固定支撑轮的数量,降低了成本;支撑轮调节装置便于安装与拆卸,降低了维修费用与维修难度;履带可根据地面实际情况调节支撑轮数量,使行驶更为方便。
