The invention discloses an automatic hook retracting device for a crane, which belongs to the technical field of crane hooks and comprises a hollow pipe, one end of the hollow pipe is fixedly connected with a box body, a push rod is slidably connected in the hollow pipe, one end of the push rod is fixedly connected with a rack, one end of the rack is fixedly connected with a clamping block, and a clamping groove is formed in the inner side surface of the box body. The inner wall of the box body is rotationally connected with a connecting shaft, the surface of the connecting shaft is fixedly connected with a sector gear, the rack is meshed with the sector gear, one side face of the box body is provided with a mounting groove, and the two side faces of the mounting groove are fixedly connected with a pair of symmetrical connecting plates. By arranging the push rod, the rack, the sector gear and the belt, the rack drives the sector gear to move through the push rod, the belt rotates to drive the rotating shaft to rotate, and therefore the hook rotates and rotates into the arc-shaped groove, automatic hook retracting of the hook is achieved, manual hook retracting by workers is not needed, and the workload of the workers is reduced.

    本发明公开了一种起重机用自动收钩装置,属于起重机挂钩技术领域,包括空心管,空心管的一端固定连接有箱体,空心管内滑动连接有推杆,推杆的一端固定连接有齿条,齿条的一端固定连接有卡块,箱体的内侧面开设有卡槽,卡块和卡槽卡接,箱体的内壁转动连接有连接轴,连接轴的表面固定连接有扇形齿轮,齿条和扇形齿轮啮合,箱体的一侧面开开设有安装槽,安装槽的两侧面固定连接有一对对称的连接板。本发明通过设置有推杆、齿条、扇形齿轮和皮带,通过推杆使得齿条带动扇形齿轮移动,使得皮带转动带动转轴转动,从而使得挂钩进行转动并转动进弧形槽内,实现了挂钩的自动收钩,无需工作人员手动进行收钩,降低了工作人员的工作量。
