Embodiment Construction
[0023] 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, not all, embodiments of the present invention.
[0024] refer to Figure 1-4 , an elevator anti-fall mechanism, 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;
[0025] 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 compression spring...

The invention relates to the technical field of elevator safety protection devices, in particular to an elevator falling prevention mechanism. The elevator falling prevention mechanism comprises an elevator body arranged in an elevator shaft, wherein the bottom of the elevator body is provided with a falling prevention device, and the falling prevention device comprises a falling triggering mechanism and a falling prevention actuating mechanism; the falling triggering mechanism comprises a shell and a plurality of supporting pieces, the multiple supporting pieces are arranged on the peripheralside of the shell, the bottom surface of a limiting plate is fixedly connected with a second connecting rod which is vertically arranged, and the bottom end of the second connecting rod is circumferentially and rotationally connected with a plurality of fourth connecting rods which are obliquely arranged upwards. According to the elevator falling prevention mechanism, the buffer and clamping fixation of an elevator are finished in an all-mechanical mode, the stability coefficient is higher, the anti-falling action is started when the elevator falls, the elevator can be prevented from fallingin time, and the safety of passengers is better protected.
Description
technical field [0001] The invention relates to the technical field of elevator safety protection devices, in particular to an elevator fall prevention mechanism. 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 ...
