Safe elevator

Abstract

The invention relates to the technical field of elevators, and concretely relates to a safe elevator, which comprises a lift car going up and down in a hoistway, a car door, a leveling door and a lift car fixing device. The lift car fixing device comprises a fixing hole formed in a hoistway wall of the hoistway under the leveling door, and an insertion column arranged on the bottom part of the lift car; the insertion column is connected with a linkage mechanism; the car door drives the insertion column to move telescopically along with the opening and the closing of the car door through the linkage mechanism; and the insertion column is inserted into the fixing hole along with the opening of the car door, and is moved out from the fixing hole to the bottom part of the lift car along with the closing of the car door. According to the safe elevator provided by the invention, when the lift car stops at a corresponding floor, the lift car fixing device can be triggered to operate along with the opening of the car door, so that the lift car is fixed onto a hoistway wall of the floor, the occurrence of the accidents such as squeezing and cutting passengers due to the up-and-down running of the lift car when the car door is not closed completely is prevented, the safety is good, the accident rate is reduced, and the passenger safety is improved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a safety elevator. Background technique [0002] At present, most elevators have protection devices to prevent people from being trapped in the elevator door in the left and right directions, but there are few protection devices in the vertical and vertical directions to prevent shearing accidents. Abnormal operation will cause people to be longitudinally sheared and squeezed by the elevator running up and down and the stationary floor. In the absence of protection devices to prevent longitudinal shear accidents, casualties will often result. As far as the elevators we see in our real life are concerned, once this kind of shear failure occurs, because there is no corresponding protection device, it will inevitably cause vicious casualty accidents and endanger people's lives. There have been many reports of such vicious accidents. Contents of the invention [0003] The purpos...
