The anti-falling safety protection device comprises a hoistway, a lift car body is arranged in the hoistway, a plurality of positioning notches are formed in the two sides in the hoistway correspondingly, and a mounting seat is fixedly mounted at the top of the lift car body. The height of the lifting block, the connecting block, the moving block, the anti-falling clamping blocks and the like can be adjusted according to the height of the elevator when the elevator breaks down and stops running and the positions of the positioning notches formed in the two sides in the shaft close to the anti-falling clamping blocks arranged at the two ends of the top of the elevator, and the flexibility of the anti-falling mechanism is improved; after the anti-falling clamping blocks are adjusted to the proper height, the position and height of the lift car body can be limited by moving the multiple anti-falling clamping blocks at the two ends into the positioning notches in the corresponding positions formed in the two sides in the hoistway, the lift car body is effectively prevented from falling, and the stability of the device is improved; and the protection performance and the safety in the maintenance process of the elevator car roof are improved.

    本发明公开了一种电梯轿厢检修用防坠安全防护装置,包括井道,所述井道内设有轿厢本体,所述井道内两侧分别开设多个定位槽口,所述轿厢本体顶部固定安装安装座。本发明可根据电梯出现故障停止运行时所处的高度以及与其顶部两端设置的若干防坠卡块相近的井道内两侧设置的定位槽口的位置,对升降块、连接块、移动块、防坠卡块等的高度进行调节,提高了防坠机构的灵活性,防坠卡块调节至合适高度后,可通过将两端的若干防坠卡块移动进入至井道内两侧设置的对应位置的定位槽口内,可对轿厢本体的位置和高度进行限位,有效防止轿厢本体坠落,提高了装置的稳定性,提高了电梯轿厢顶检修过程中的防护性和安全性。
