The invention relates to the technical field of machining, and discloses a crane separating device for an automobile crane. The crane separating device comprises an equipment shell and a mounting shaft. The mounting shaft is movably connected to the interior of the equipment shell, a winding shaft is movably connected to the outer side of the mounting shaft, a hoisting cable is movably connected to the outer side of the winding shaft, and a movable groove is formed in the winding shaft. The inner wall of the movable groove is fixedly connected with a connecting spring, the outer side of the connecting spring is fixedly connected with a moving contact, the inner wall of the movable groove is fixedly connected with a fixed contact, and the interior of the equipment shell is fixedly connected with a magnet filling block. Magnetic repulsive force is generated between a first magnetic block and a first electromagnet, so that the first magnetic block moves inwards along an adjusting groove, at the moment, the first magnetic block drives a first connecting rod to drive, the first connecting rod and a first fixing shaft form a winding shaft driving mechanism, a winding shaft rotates in the anticlockwise direction, the hoisting cable is rolled up, a heavy object is prevented from falling, and accidents are prevented.

    本发明涉及机械加工技术领域,且公开了汽车起重机的车吊分离装置,包括设备壳体和安装轴,所述设备壳体内部活动连接有安装轴,所述安装轴外侧活动连接有绕线轴,所述绕线轴外侧活动连接有起吊线缆,所述绕线轴内部开设有活动槽,所述活动槽内壁固定连接有连接弹簧,所述连接弹簧外侧固定连接有动触头,所述活动槽内壁固定连接有定触头,所述设备壳体内部固定连接有磁铁填充块。通过第一磁性块与第一电磁铁之间产生磁性排斥力,使得第一磁性块沿着调节槽向内移动,此时第一磁性块带动第一连杆驱动,第一连杆与第一固定轴形成绕轴驱动机构,将绕线轴沿着逆时针方向转动,收卷起吊线缆,制止重物下坠,防止出现意外事故。
