The invention discloses a damping device capable of achieving elevator emergency protection. The damping device comprises a box body, wherein the interior of the box body comprises an inner cavity, multiple speed reduction devices which are symmetric left and right and are arrayed up and down are arranged on the inner wall of the inner cavity, and internally comprise linkage cavities which are located in the inner wall of the inner cavity, fixed blocks are fixedly arranged on the inner walls of the upper sides of the linkage cavities, fixed shafts are rotatably connected to the lower sides ofthe fixed blocks, and connecting rods are rotatably connected to the rear sides of the fixed blocks and the fixed shafts. According to the damping device, through the rapid descending of an elevator,huge air pressure which then triggers the speed reduction devices is generated, and the speed reduction devices lower the elevator descending speed through friction; and meanwhile, damping device bodies are triggered to inflate a lower baseboard, so that the damping distance is increased, and the damping effect is enhanced. According to the damping device, a cleaning device cleans away oil foulingat the lower side, and an oil baffle plate prevents the speed reduction devices and the damping device bodies from being jammed by the oil fouling.
