| description | 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 |
