A protective car buffer device in an elevator shaft

Abstract

The invention provides a protective car cushioning device in an elevator shaft. The protective car cushioning device is characterized in that a cushioning mechanism comprises a cushioning frame and a protective cushioning device, a car can be cushioned by the cushioning frame, and falling objects in the elevator shaft can be cushioned by the protective cushioning device; the cushioning frame comprises four elastic support columns and connecting beams, the elastic support columns are correspondingly separately arranged at four corners of the bottom of the elevator shaft, and the connecting beams are arranged between the adjacent elastic support columns in a connected manner; the protective cushioning device comprises an upper cushioning layer and a lower cushioning layer, the upper cushioning layer is positioned on the upper side of the protective cushioning device, the lower cushioning layer is positioned on the lower side of the protective cushioning device, and gaps are reserved between the lower cushioning layer and the upper cushioning layer; the upper cushioning layer comprises an elastic net layer, a sponge layer, an elastic air cushion layer and an accommodating frame, the elastic net layer is positioned on the upper side of the upper cushioning layer, the sponge layer is positioned on the lower side of the elastic net layer, the elastic air cushion layer is positioned on the lower side of the sponge layer, and the elastic net layer, the sponge layer and the elastic air cushion layer are accommodated by the accommodating frame; the lower cushioning layer comprises an elastic water cushion layer filled with water. The protective car cushioning device has the advantages that impact force on human bodies can be effectively cushioned via three steps of different cushioning phases, accordingly, the human bodies can ultimately steadily stop on the elastic net layer, and the personal safety of personnel can be guaranteed.
