The invention discloses a telescopic stable supporting leg which comprises fixed arms, bent movable arms, a telescopic oil cylinder assemblies and a vertical oil cylinder assembly. The number of the fixed arms is two, the two fixed arms are fixed on an auxiliary frame in an outer splayed shape, the two bent movable arms are movably installed on the two fixed arms respectively, the movable ends of the bent movable arms are located in the fixed arms, stretching and retracting of the bent movable arms are achieved through telescopic oil cylinder assemblies, and the bent ends of the bent movable arms on the two sides are parallel to each other. A vertical oil cylinder assembly is vertically installed at the bent end of each bent movable arm, the vertical oil cylinder assembly is in a retracted state in the transportation state, and the vertical oil cylinder assembly is in an extended state in the erecting operation. The problems that the anti-overturning stabilizing moment of equipment of a special vehicle used in a narrow region is insufficient under the condition that the working site and space are limited, and the width of supporting legs does not exceed the width of a bridge in the transportation state can be solved.

    本发明公开了一种伸缩式稳定支腿,包括固定臂、折弯型活动臂、伸缩油缸组件及垂直油缸组件;固定臂为两个,呈外“八”字固定在副车架上,两个折弯型活动臂分别活动安装在两个固定臂上,折弯型活动臂活动端位于固定臂内,并通过伸缩油缸组件实现折弯型活动臂的伸出和收回,两侧的折弯型活动臂折弯端互相平行;折弯型活动臂折弯端竖直安装有垂直油缸组件,运输状态时垂直油缸组件处于收回状态,架设作业时垂直油缸组件处于伸出状态。本发明能够解决狭窄地域使用的专用车辆在工作场地和空间有限情况下装备抗倾覆稳定力矩不够的问题,以及在运输状态下支腿宽度不超桥宽的问题。
