The invention relates to the technical field of elevator protection, in particular to a locking device for preventing an elevator from falling down, and solves the defects in the prior art. The locking device for preventing the elevator from falling down comprises a shaft and an elevator car, wherein the inner wall of the shaft is provided with limiting grooves, the inner walls of the limiting grooves are fixedly connected with stop blocks distributed in an array through bolts, the tops of the stop blocks are bonded with damping silica gel pads, the top of the elevator car is fixedly connectedwith a traction rope, and the top of the elevator car is sequentially fixedly connected with symmetrically-arranged supporting plates and fixing plates through hexagonal screws. Through the arrangement of structures such as baffle plates, needle rods, the stop blocks, the damping silica gel pads and the like, after the elevator car starts the locking device, the baffle plates which are indirectlyconnected with the elevator car are blocked by the stop blocks, the elevator can be effectively locked by using the multiple protection stop blocks and the baffle plates, meanwhile, the elevator is damped by the silica gel during locking, and the impact force of the elevator is absorbed to the maximum extent, so that the injury degree of personnel is reduced, and the protection strength is high.

    本发明涉及电梯防护技术领域,尤其涉及用于防止电梯下坠锁紧装置,解决现有技术中存在的缺点,包括井道和轿厢,所述井道的内壁开设有限位槽,所述限位槽的内壁均通过螺栓固定连接有呈阵列分布的挡块,挡块的顶部均粘接有减震硅胶垫,所述轿厢的顶部固定连接有牵引绳,且轿厢的顶部依次通过六角螺钉固定连接有对称布置的支撑板和固定板,通过挡板、针杆、挡块、减震硅胶垫等结构的设置,在轿厢启动锁紧装置后,与轿厢间接连接的挡板由挡块挡住,利用多道防护挡块和挡板可以有效地将电梯锁紧,同时在锁紧时通过硅胶进行减震,在最大程度上吸收电梯的冲击力,以此来减小人员的受伤程度,防护强度高。
