The invention discloses an anti-falling safety elevator, and relates to the field of elevators. The elevator comprises a channel wall, an elevator car and a bearing rope, wherein a strip-shaped groove is formed in the surface of one side of the channel wall, a limiting rack is formed in the strip-shaped groove, the bearing rope is fixedly connected to the top of the elevator car, a containing plate is fixedly mounted at the top of the elevator car, and two symmetrically-arranged locking mechanisms are fixedly mounted on the upper surface of the containing plate; each locking mechanism comprises a sleeve, a locking block and a spring, wherein the locking block is movably connected to one side of the sleeve in a sleeving mode, the spring is located in the sleeve, a plurality of clamping heads matched with the limiting racks are formed at the end, far away from the bearing rope, of the locking block, and a limiting rope is fixedly connected between a bearing rope and a locking block. When the arranged bearing rope does not bear the mass of a car any more, the spring in a contraction state pushes the locking block to move towards the limiting rack, so that the clamping heads are clamped into the limiting rack, and then the car is prevented from falling down.

    本发明公开了防坠落的安全性电梯,涉及电梯领域。本发明包括通道墙、轿厢和承重绳,通道墙的一侧表面开设有条形凹槽,条形凹槽的内部成型有限位齿条,承重绳固定连接在轿厢的顶部,轿厢的顶部固定安装有放置板,放置板的上表面固定安装有两个对称设置的锁紧机构;锁紧机构包括套筒、锁紧块和弹簧,锁紧块活动套接在套筒的一侧,弹簧位于套筒的内部,锁紧块远离承重绳的一端成型有若干与限位齿条相适配的卡头,承重绳与锁紧块之间固定连接有限位绳。本发明设置的承重绳不再承受轿厢的质量时,处于收缩状态的弹簧推动锁紧块向限位齿条运动,使卡头卡入限位齿条内,进而阻止轿厢下坠。
