The invention provides a rotary pin plugging and pulling mechanism and an automobile crane, and relates to the technical field of cranes. The rotary pin plugging and pulling mechanism comprises a telescopic assembly, a limiting assembly and a first mounting seat, wherein the first mounting seat is mounted on a main arm of a cargo boom; the telescopic assembly and the limiting assembly are mountedon the first mounting seat; the telescopic assembly is used for driving a rotary pin to be plugged and pulled; and the limiting assembly is used for limiting the telescopic assembly when the telescopic assembly stretches and retracts to predetermined positions. The automobile crane is provided with the rotary pin plugging and pulling mechanism, and the limiting assembly is used for limiting the telescopic assembly, so that the telescopic assembly is prevented from retracting due to misoperation or other reasons, then the situation that an auxiliary arm of the automobile crane falls off when the rotary pin is pulled out is avoided, and the driving safety of the automobile crane is guaranteed.
本发明提供了一种回转销插拔机构及汽车起重机,涉及起重机技术领域。回转销插拔机构包括伸缩组件、限位组件及第一安装座,第一安装座安装于起重臂的主臂上,伸缩组件和限位组件安装于第一安装座,伸缩组件用于驱动回转销插拔,限位组件用于在伸缩组件伸缩至预定位置时对伸缩组件进行限位。汽车起重机安装有上述的回转销插拔机构,限位组件对伸缩组件进行限位,避免伸缩组件由于误操作或者其它原因收缩,从而避免回转销拔出造成汽车起重机的副臂脱落,保证了汽车起重机的行车安全。
