Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0023] refer to Figure 1-4 , an elevator safety protection device, including an elevator body 18 arranged inside the elevator shaft, the bottom of the elevator body 18 is provided with an anti-fall device, and the anti-fall device includes a fall trigger mechanism and an anti-fall actuator;

[0024] The fall trigger mechanism includes a housing 5 and several support members 8, and several support members 8 are arranged on the peripheral side of the housing 5. There is a limit plate 1 that can slide up and down inside, and a first spring 2 is provided between the top surface of the limit plate 1 and the top wall of the housing 5, the first spring 2 is a...

Abstract

The invention relates to the technical field of elevator safety protection apparatuses, particularly to an elevator safety protection apparatus. The elevator safety protection apparatus comprises an elevator body disposed in an elevator shaft; a fall prevention apparatus is provided at the bottom of the elevator body, and comprises a fall trigger mechanism and a fall prevention execution mechanism; the fall trigger mechanism comprises a housing and multiple support members; the multiple support members are arranged on the peripheral side of the housing; a second connecting rod vertically arranged is fixedly connected to the bottom surface of the limiting plate; and multiple four connecting rods inclined upwards are rotatably connected to the peripheral direction of the bottom end of the second connecting rod. The apparatus completes damping and clamping fixation of an elevator in a full mechanical manner to achieve higher stability coefficient; and because the apparatus starts a fall prevention action when the elevator falls, the fall of the elevator can be timely stopped, and the safety of passengers is preferably protected.

Description

technical field [0001] The invention relates to the technical field of elevator safety devices, in particular to an elevator safety protection device. Background technique [0002] During the working process of the elevator, if the lifting device breaks down, it will cause the elevator to stop moving, or cause the elevator to fall, which will threaten the lives of passengers. [0003] Now people will install a buffer device at the bottom of the elevator shaft. When the elevator falls, the elevator falls on the buffer device for buffering to reduce the risk of falling. However, this kind of buffer device has the following disadvantages: 1. The higher the floor, the lower the buffer device. The worse the buffering effect is, when the elevator falls from a high place, under the action of gravity, the buffering device will exceed the upper line of the buffering load, which will be directly damaged, and the buffering effect will be negligible; 2. The buffering device cannot be ac...
