Abstract

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.

Description

technical field [0001] The invention relates to the field of crane outriggers, in particular to an outrigger structure and a truck crane. Background technique [0002] A car crane is a kind of crane installed on an ordinary car chassis or a special car chassis, and its driving cab is set separately from the lifting control room. At present, the movable outriggers of GM cranes are connected to the fixed outrigger box of the frame, and the span adjustment of the movable outriggers is very limited, which requires strict requirements on the working terrain. [0003] For example, in the patent document (CN110304561A), the connecting frame is fixed on the crane platform through the platform connecting shaft, and one end of the inner movable leg is movably connected with the connecting frame, and the inner movable leg can only swing up and down relative to the crane platform, while the inner movable leg The range of adjustment of the legs is very limited.
