The embodiment of the invention provides a supporting leg structure and an automobile crane, relates to the field of crane supporting legs, and aims to solve the problems that an existing supporting leg is small in span adjustable range and high in operation site requirement. The supporting leg structure comprises a chassis, a movable supporting leg and a hinged seat, the hinged seat is connectedto the chassis in a swinging manner, the movable supporting leg is connected to the hinged seat in a swinging manner; in the process that the hinged seat swings relative to the chassis, the movable supporting leg swings on the horizontal plane; and in the process that the movable supporting leg swings relative to the hinged seat, the movable supporting leg swings on the vertical plane. The automobile crane comprises the supporting leg structure. The movable supporting leg can swing on the horizontal plane and the vertical plane, so that the span of the movable supporting leg in the length direction and the width direction of the chassis is adjustable, the movable supporting leg can be suitable for various terrain operations, and the operation site requirement is low.
本发明的实施例提供了一种支腿结构及汽车起重机,涉及起重机支腿领域。旨在改善现有的支腿跨距可调范围小,作业场地要求高的问题。其包括底盘、活动支腿以及铰接座;铰接座可摆动地连接于底盘,活动支腿可摆动地连接于铰接座;铰接座相对底盘摆动的过程中,使活动支腿在水平面摆动;活动支腿相对铰接座摆动的过程中,使活动支腿在竖直面摆动。汽车起重机包括支腿结构。活动支腿在水平面以及竖直面均可摆动,使活动支腿沿底盘长度方向以及宽度方向的跨距均可调,能够适用于多种地形作业,作业场地要求低。
