The invention relates to the technical field of railway tracks, and discloses a rail hoisting vehicle hoisting mechanism capable of preventing rail hoisting stalling from hurting people. The rail hoisting vehicle hoisting mechanism comprises a fixed disc, wherein a limiting mechanism is arranged in the fixed disc, and a rotating disc is movably connected into the fixed disc. According to the railhoisting vehicle hoisting mechanism capable of preventing rail hoisting stalling from hurting people, when the hoisting mechanism stalls, a balancing weight drives a first contact and a second contactto make contact under the effect of centrifugal force, an electrorheological fluid is further changed into a solid from liquid, a limiting rod can be clamped in a limiting groove at the moment, the rotating disc cannot rotate, and therefore the effect that the hoisting mechanism stalls and is self-locked to prevent a rail from falling to hurt people is achieved. A reset rod is pulled downwards, the balancing weight moves to a first movable cavity from a second movable cavity at the moment, the interior of the electrorheological fluid is not powered on, the limiting rod cannot be clamped in the limiting groove at the moment, and therefore the effect of rapidly releasing self-locking of the hoisting mechanism is achieved.

    本发明涉及铁路轨道技术领域,且公开了一种避免铁轨吊装失速伤人的铁轨吊装车吊装机构,包括固定盘,所述固定盘的内部设置有限位机构,所述固定盘的内部活动连接有转动盘。该避免铁轨吊装失速伤人的铁轨吊装车吊装机构,当吊装机构发生失速现象时,此时配重块在离心力的作用下带动触点一与触点二接触,进一步使得电流变体由液体变为固体,此时限位杆会卡在限位槽的内部,进一步使得转动盘无法转动,从而达到了吊装机构失速自锁防止铁轨坠落伤人的效果。向下拉动复位杆,此时配重块从第二活动腔运动到第一活动腔,进一步使得电流变体的内部不通电,此时限位杆不会卡在限位槽的内部,从而达到了快速解除吊装机构自锁的效果。
