Document Type and Number:
WIPO Patent Application WO/2021/249434
Kind Code:
A1
Abstract:
An anti-falling and vibration-dampening elevator car, comprising an elevator car body (1). A sealing door body (2) is snap-connected to a side edge of the elevator car body (1). The top surface and the bottom surface of the elevator car body (1) are symmetrically sleeved with fixing plates (3). Inserting channels (4) are symmetrically formed in the top surface of each fixing plate (3). A vertical guide rail (5) is vertically inserted into an inner side edge of each inserting channel (4). Sealing rods (6) are horizontally welded to the top and the bottom of the vertical guide rail (5). Jacking cylinders (7) are evenly connected to the top surface and the bottom surface of the fixing plates (3) by means of bolts. A sliding groove (8) is vertically formed in a side edge of each vertical guide rail (5). The elevator car is more direct and efficient in falling prevention, and adopts a multiple vibration-dampening structure to achieve a buffering effect during an emergency stop, so that the internal protection is more comprehensive.
