The invention relates to the technical field of elevator car falling protection self-locking, and discloses an elevator car falling protection self-locking device which comprises a fixing plate, sliding rail clamping grooves are formed in the two ends of the fixing plate, and elevator sliding rails are slidably connected to the sliding rail clamping grooves. By arranging the buffering mechanism, after the elevator car is locked by the self-locking mechanism, the self-locking rotating disc stops sliding down, at the moment, the self-locking rotating disc drives the sliding plate fixedly connected with the self-locking rotating shaft to stop falling down, and at the moment, under the inertia effect of the elevator car, the sliding plate still tends to continue falling down; at the moment, the fixing plate drives the elevator car body to downwards extrude the energy absorption springs, the first moving blocks slide on the buffering sliding rods, the energy absorption springs at the upper ends of the first moving blocks contract under extrusion of the fixing plate, absorb kinetic energy and convert the kinetic energy into elastic potential energy of the energy absorption springs, and therefore the buffering effect can be better provided for the elevator car falling rapidly.

    本发明涉及电梯轿厢坠落防护自锁技术领域,且公开了一种电梯轿厢坠落防护自锁装置,包括固定板,固定板的两端开设有滑轨卡槽,滑轨卡槽上滑动连接有电梯滑轨。本发明通过设置缓冲机构,当自锁机构锁定电梯轿厢后,自锁转盘停止下滑,这时自锁转盘带动与自锁转轴固定连接的滑动板停止向下坠落,这时在电梯轿厢的惯性作用下还有继续向下坠落的趋势,这时固定板带动电梯轿厢本体向下挤压吸能弹簧,这时移动块一在缓冲滑杆上滑动,此时移动块一上端的吸能弹簧在固定板的挤压下收缩并吸收动能转化为吸能弹簧的弹性势能,这样设置有利于为快速下坠的电梯轿厢提供缓冲效果。
