The invention is suitable for the technical field of elevator cars, and provides an elevator car safety protection device which comprises a car and a traction steel cable and further comprises a T-shaped guide rail, a fixed plate, a guide shaft, a movable plate, a connecting plate, an anti-falling claw, a first spring, a shock absorber, a connecting steel cable, a guide assembly, a trigger mechanism, a fixed connecting assembly and a reciprocating moving assembly. When the lift car suddenly descends, the connecting steel cable loses traction force, the triggering mechanism relieves limitation on the anti-descending claw in the mode that the connecting steel cable loses the traction force, the first spring on the moving plate pushes the anti-descending claw, then the anti-descending claw on the moving plate is meshed with the ratchet groove, and therefore the moving plate does not continue to move downwards; the fixed connecting assembly relieves movement limitation on the movable plate through the triggering mechanism, at the moment, the lift car and the fixed plate continue to move downwards under the guiding effect of the guiding shaft, the movable plate and the fixed plate lengthen the shock absorber, then the shock absorber achieves the shock absorption effect, and the situation that the lift car suddenly stops and impacts a human body is avoided.
本发明适用于电梯轿厢技术领域,提供了一种电梯轿厢安全保护装置,包括轿厢和曳引钢索,还包括:T形导轨、固定板、导向轴、移动板、连接板、防降爪、第一弹簧、减震器、连接钢索、导向组件、触发机构、固定连接组件和往复移动组件。轿厢骤降时,连接钢索也失去牵引力,触发机构通过连接钢索失去牵引力的方式解除对防降爪的限制,移动板上的第一弹簧推动防降爪,进而使移动板上的防降爪与棘齿槽啮合,从而使移动板不继续向下移动,固定连接组件通过触发机构解除对移动板的移动限制,此时轿厢和固定板在导向轴的导向作用下继续向下移动,移动板和固定板拉长减震器,进而使减震器起到减震的效果,避免轿厢骤停而对人体产生冲击。
