The invention relates to the technical field of elevator operation safety, and discloses an elevator falling buffering device which comprises a wall body and an elevator car body, guide rails are fixedly installed on the two sides of the interior of the wall body, the elevator car body is movably connected with the guide rails in a clamped mode, and a counterweight device is fixedly installed on the inner wall of the wall body and located on the back face of the elevator car body. Through the arrangement of the abutting roller and the balancing weight, when an elevator is out of control and falls, the electromagnetic device is powered on, the abutting roller is pushed out, after being pushed out, the abutting roller slides downwards along the sliding limiting groove and falls to the position below the elevator car body, when the elevator car body falls, the elevator car body makes contact with the abutting roller and drives the abutting roller to press downwards together, and then under the supporting of the supporting roller, the elevator car body is driven to move downwards. The abutting roller pulls the balancing weight to ascend through the speed limiting steel rope so as to slow down falling of the elevator car body and force the elevator car body to stop falling, and the situation that the elevator car body directly falls to the shaft bottom, large impact is formed, and casualties occur is avoided.

    本发明涉及电梯运行安全技术领域,且公开了一种用于电梯坠落缓冲用装置,包括墙体和电梯箱体,所述墙体的内部两侧固定安装有导轨,所述电梯箱体与导轨活动卡接,所述墙体的内壁上且位于电梯箱体的背面固定安装有对重装置。通过抵压辊和配重块的设置,使得电梯失控下坠时,对电磁装置进行通电,将将抵压辊推出,抵压辊被推出后,顺着滑动限位槽下滑动,落到电梯箱体的下方,当电梯箱体下落时,则与抵压辊接触,并将抵压辊一起带动下压,随后,在支撑辊的支撑下,抵压辊通过限速钢绳拉动配重块上升,用以减缓电梯箱体的下坠,迫使电梯箱体停止下坠,避免电梯箱体直接坠落到井底,形成较大冲击,出现人员伤亡。
