The invention relates to the technical field of winches, and discloses a winch stall self-locking device capable of preventing an equipment stall from influencing the safety of an operator. The winch stall self-locking device comprises a rotating shaft, wherein a rotating disc is fixedly connected to the outer wall of the rotating shaft, a sliding groove is formed in the right side of the rotating disc, and an electrorheological body is movably connected in the sliding groove. According to the winch stall self-locking device capable of preventing the equipment stall from influencing the safety of the operator, when the stall of a winch happens, a first contact makes contact with a second contact, then the electrorheological body is changed into a solid state from a liquid state, limiting blocks can be clamped in limiting grooves at the moment, the rotating shaft cannot rotate at the moment, and thus the effect of preventing the stall of the winch in the hoisting process is achieved. When a disc is pulled upwards, a movable block can deflect upwards, then the first contact and the second contact are separated, the liquid state of the electrorheological body is recovered at the moment, the rotation of the rotating shaft can be recovered at the moment, and therefore the effect of conducting recycling to save resources is achieved.

    本发明涉及绞车技术领域,且公开了一种避免设备失速影响操作员安全的绞车失速自锁装置,包括转动轴,所述转动轴的外壁固定连接有转动盘,所述转动盘右侧的内部开设有滑槽,所述滑槽的内部活动连接有电流变体。该避免设备失速影响操作员安全的绞车失速自锁装置,当绞车发生失速现象时,此时触点一与触点二接触,进一步使得电流变体从液体变为固体,此时限位块会卡在限位槽的内部,此时转动轴无法转动,从而达到了防止绞车在起吊过程中发生失速情况发生的效果。向上扳动圆盘,此时活动块也会向上偏转,进一步使得触点一和触点二分离,此时电流变体恢复成液体,此时转动轴可以恢复转动,从而达到了可以循环使用节约资源的效果。
