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.
本发明实施例提供一种摆动支腿限位组件和起重机,涉及起重机领域。该摆动支腿限位组件包括:安装座,安装座用于安装在起重机上;支腿件,支腿件与安装座转动连接,且支腿件用于与起重机的动力部件传动连接;限位件,限位件与安装座连接,用于在支腿件相对安装座绕第一转动方向转动的情况下,限位支腿件于第一止挡位置,且限位件还用于在支腿件相对安装座绕第二转动方向转动的情况下,限位支腿件于第二止挡位置,其中,第一转动方向与第二转动方向相反,支腿件在第一止挡位置和第二止挡位置之间的范围内转动。本发明实施例的结构简单、性能可靠,并且可操作性强、通用性好。
