The cable crane comprises a walking truss, a machine body, a motor, a cable, a self-rotating rod, a rotating piece, a fixed ring, a wedge-shaped block, a movable plate, a rotating plate, an abutting piece and a switching piece. When the lifting hook is put down, the motor is started, the abutting piece rotates in a reciprocating mode through the rotating piece, the abutting piece abuts against the wedge-shaped block on one fixing ring, clearance rotation of the fixing rings and matched fixation of the stabilizing piece are made to be consistent all the time, and the rotation directions are repeated in sequence, so that the lifting hook below the mooring rope is put down stably at intervals, and the situation that the lifting hook is put down or lifted up too fast is avoided; and potential safety hazards are avoided. The interval movement interval is small and continuous, and the influence on the hoisting efficiency is small; when the lifting hook is lifted, the rotating direction of the motor is not changed through the switching piece, so that the other fixing ring rotates in a clearance mode, the rotating directions are opposite, the lifting hook below the mooring rope is lifted stably at intervals, the rotating direction of the motor does not need to be switched, and loss of a bearing of the motor is reduced.

    本发明公开了一种缆索起重机,包括行走桁架、机体、电机、缆绳、自转杆、转动件、固定环、楔形块、活动板、转动板、抵压件、切换件;吊钩下放时,启动电机,通过转动件,使抵压件做往复转动,抵压件抵压其中一个固定环上的楔形块,使固定环间隙的转动,稳定件配合的固定,且转动的方向始终一致,依次反复,从而使缆绳下的吊钩间隔平稳的下放,避免吊钩下放或上提过快,造成安全隐患。本发明中的间隔运动间隔小而连续,对于吊装效率的影响小;吊钩上提时通过切换件,电机转动方向不变,从而使另一个固定环间隙的转动,且转动的方向相反,使缆绳下的吊钩间隔平稳的上提,本申请不需要切换电机的转动方向,减少对电机的轴承的损耗。
