Abstract

The invention discloses a safe elevator comprising an elevator shaft and a lift car; each layer of the elevator shaft is provided with an elevator opening; an elevator door is mounted at the elevator opening; the lift car is positioned inside the elevator shaft; even number of safe devices are mounted inside the elevator shaft; every two safe devices are set as a group, the safe devices of the same group are positioned at a same installation height, one is positioned at the elevator opening and the other is positioned at the other side, corresponding to the elevator opening, of the elevator shaft; the safe device comprises a cylinder, an extension spring and a support board; one end of the support board is hinged to the elevator shaft; one end of the extension spring is connected to the elevator shaft and the other end is connected to the support board; a pedestal of the cylinder is mounted on the elevator shaft; a push rod of the cylinder is hinged to the lower surface of the support board; the cylinders of all safe devices are connected to one controller; a switch of the controller is installed inside the lift car. By means of the safe elevator of the invention, falling accidents are avoided when elevator wire ropes are broken.

Description

technical field [0001] The invention relates to an elevator, in particular to a safety elevator. Background technique [0002] Elevator safety accidents have occurred frequently this year, bringing hidden dangers to people's lives and property. Elevators are tools that people touch every day. The utilization rate of elevators is also very high. While elevators bring convenience to people going upstairs, they also have certain safety hazards. Once the wire rope breaks, a major safety accident will be caused. Because the probability of wire rope fracture in existing elevators is very low, therefore, safety devices are seldom provided to prevent the elevator from falling into a well accident. Contents of the invention [0003] In order to overcome the fact that the existing elevators are not equipped with safety devices to prevent the accident of falling into a well, the present invention provides a safety elevator, which can prevent the accident of falling into a well when...
