Abstract

The embodiment of the invention provides a swinging supporting leg spacing component and a crane, and relates to the field of cranes. The swinging supporting leg spacing component comprises an installation seat, a supporting leg component and a spacing element, wherein the installation seat is used for being installed on the crane; the supporting leg component and the installation seat are rotatably connected, and the supporting leg component is used for carrying out transmission connection with the power component of the crane; the spacing component is connected with the installation seat andis used for spacing the supporting leg component to be positioned on a first stop position under a situation that the supporting component rotates around a first rotation direction relative to the installation seat; in addition, the spacing component is also used for spacing the supporting leg component to be positioned on a second stop position under a situation that the supporting component rotates around a second rotation direction relative to the installation seat, wherein the first rotation direction and the second rotation direction are opposite; and the supporting leg component rotatesin a range between the first stop position and the second stop position. The embodiment of the invention has a simple structure and is reliable in performance, high in operability and good in universality.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a swing leg limiting assembly and a crane. Background technique [0002] The swing outriggers of the crane bear all the loads of the whole machine during hoisting, and the swing angle needs to be adjusted in time according to the actual working conditions. The limit of the outriggers is very important to ensure the swing angle. [0003] At present, the limit of the swing leg is mostly guaranteed by the stroke of the hydraulic cylinder. The swing angle cannot be adjusted in real time. To change the swing angle, only the oil cylinder with a different stroke has to be replaced, which is costly and inconvenient. Contents of the invention [0004] The object of the present invention is to provide a swing leg limiting assembly and a crane, which have simple structure, reliable performance, strong operability and good versatility. [0005] Embodiments of the present invention are achieved like ...
