The invention relates to the technical field of cranes, in particular to an automatic crane for hoisting and assembling an engineering machinery cab, which comprises a rail beam, a support column, a bridge frame and a walking trolley, the cage-shaped shear fork telescopic piece comprises a top frame fixed on the walking trolley, two shear fork type connecting rods of which the top ends are connected to the top frame, a bottom plate of which the top surface is connected to the bottom ends of the shear fork type connecting rods, and a telescopic cylinder for driving the shear fork type connecting rods to vertically stretch out and draw back; the supporting frame is fixed to the bottom face of the bottom plate, the tops of the grabbing mechanisms are slidably connected to the two sides of the supporting frame in the transverse direction, the driving mechanism drives the grabbing mechanisms on the two sides to synchronously and reversely move, and overturning plates capable of vertically swinging and rotating are arranged on the inner sides of the bottom ends of the grabbing mechanisms. The clamping fixing part comprises a vertical plate fixed on the outer side wall of the grabbing mechanism, a supporting seat fixed at the top end of the outer side wall of the vertical plate, a clamping plate with one end hinged to the outer end of the supporting seat, and a transmission mechanism fixed on the supporting seat and used for driving the clamping plate to swing and rotate; therefore, the crane can stably hoist the engineering machinery cab.

    本发明涉及起重机技术领域,具体为用于工程机械驾驶室吊装装配的自动化起重机,包括轨梁、支柱、桥架以及行走小车,笼状剪叉伸缩件包括固定于行走小车的顶架、顶端连接于顶架的两个剪叉式连杆、顶面连接于剪叉式连杆底端的底板以及驱动剪叉式连杆竖向伸缩的伸缩缸,抓取起吊件包括固定于底板底面的支撑架、顶部沿横向滑动连接于支撑架两侧的抓取机构以及驱动两侧抓取机构同步反向运动的驱动机构,抓取机构底端内侧设有可竖向摆转的翻转板,夹持固定件包括固定于抓取机构外侧壁的立板、固定于立板外侧壁顶端的支撑座、一端铰接于支撑座外端的夹板以及固定于支撑座上且用于驱动夹板摆转的传动机构;以实现起重机对工程机械驾驶室的平稳吊装。
