The invention relates to the technical field of railway parts, and discloses a railway track hoisting device capable of effectively reducing the occurrence probability of stall accidents. The railway track hoisting device comprises a base, a fixing rod is fixedly connected to the top of the left side of the base, a fixing disc is fixedly connected to the right side of the fixing rod, a limiting groove is formed in the fixing disc, and a driving disc is movably connected to the interior of the fixing disc. According to the railway track hoisting device capable of effectively reducing the occurrence probability of stall accidents, when a stall phenomenon occurs, a metal ball moves away from a driven disc at the moment, a movable contact is further made to be in contact with a fixed contact, a limiting rod is clamped in the limiting groove at the moment, the driving disc is further made to stop rotating, and therefore, the effect that the railway track hoisting device is self-locked when stalls, so that falling and hurting of people are prevented is achieved. The movable contact and the fixed contact are electrically connected with an electromagnetic device, so that the overall response speed of the device is very high, and the effect of effectively avoiding the influence of response delay on the reliability of the device is achieved.
本发明涉及铁路部件技术领域,且公开了一种有效降低失速事故发生概率的铁路轨道吊装装置,包括底座,所述底座左侧的顶部固定连接有固定杆,所述固定杆的右侧固定连接有固定盘,所述固定盘的内部开设有限位槽,所述固定盘的内部活动连接有主动盘。该有效降低失速事故发生概率的铁路轨道吊装装置,当发生失速现象时,此时金属球做远离从动盘运动,进一步使得活动触点与固定触点接触,此时限位杆卡在限位槽的内部,进一步使得主动盘停止转动,从而达到了铁路轨道吊装装置失速自锁避免坠落伤人的效果。由于活动触点与固定触点和电磁装置为电连接关系,所以该装置的整体反应速度会非常快速,从而达到了有效避免反应延迟影响装置可靠性的效果。
