The invention relates to the technical field of cable installation, and discloses a crane hanging scaffold stall self-locking mechanism based on cable hoisting, the crane hanging scaffold stall self-locking mechanism comprises a base, the top of the base is fixedly connected with a first fixed column, the top of the first fixed column is movably connected with a first rotating disc, and the interior of the first rotating disc is fixedly connected with a first rotating shaft. For the crane hanging scaffold stall self-locking mechanism based on cable hoisting, when a stall phenomenon occurs in the hoisting process, the first metal ball makes contact with the negative electrode contact at the moment, magnetism is changed, the cross rod attracts the first metal ball at the moment, the second metal ball makes contact with the ball at the moment, the electro-rheological body is powered on, and therefore the effect that the electro-rheological body is changed into a solid state from a liquidstate is achieved. At the moment, a limiting column is clamped in a first groove under the action of centrifugal force and an electro-rheological body, a second rotating disc stops rotating at the moment, a first rotating shaft further stops rotating, and therefore the effects of stall self-locking of the hanging scaffold and sudden falling prevention are achieved.

    本发明涉及电缆安装技术领域,且公开了一种基于电缆吊装的吊车吊盘失速自锁机构,包括底座,所述底座的顶部固定连接有固定柱一,所述固定柱一的顶部活动连接有转动盘一,所述转动盘一的内部固定连接有转动轴一。该基于电缆吊装的吊车吊盘失速自锁机构,当吊装过程中发生失速现象时,此时金属球一与负极触点触碰,进而改变磁性,此时横杆会吸引着金属球一,此时金属球二与圆球接触,使得电流变体通电,从而达到了电流变体由液态变为固体的效果。此时限位柱在离心力和电流变体的作用下,卡接在凹槽一的内部,此时转动盘二停止转动,进一步使得转动轴一停止转动,从而达到了吊盘失速自锁,防止突然坠落的效果。
