Embodiment Construction

[0030] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0031] Such as Figure 1 to Figure 8 Said, the anti-fall elevator of the present invention comprises T-shaped elevator guide rail 1 and car 2 arranged in the elevator shaft, and the two sides of the car 2 are respectively provided with car 2 guide shoes matched with the elevator guide rail 1, There is a traction sheave driven by the traction machine in the machine room at the upper part of the elevator shaft. The traction machine drives the traction wire rope through the traction wheel. There is also a speed limiter inside, and an expansion rope pulley is set at the bottom of the elevator shaft. The speed limiter steel wire rope 3 forms a closed loop through the speed limiter rope pulley and the expansion rope pulley. The connecting rod is connected with the safety gear, and the above-mentioned structure is the conventional structure of the elevator, so it will...

Abstract

The invention discloses an anti-falling elevator. The anti-falling elevator comprises a T-shaped elevator guide rail, a lift car, a hooking support device, a hooking support excitation device, hanging and pulling mechanisms and support holes, wherein the T-shaped elevator guide rail and the lift car are arranged in an elevator shaft, lift car guide shoes are respectively arranged on both sides of the lift car, the hooking support device and the hooking support excitation device are arranged on the lift car, and the hanging and pulling mechanisms and the support holes are arranged on and formed in the side walls of both sides of the elevator shaft; the hooking support device comprises a right hooking support sub-mechanism and a left hooking support sub-mechanism, the right hooking support sub-mechanism comprises a right hanging rod with a hook, a right fixed shaft, a right driving rod, a right support rod and a right elevator guide rail clamping excitation structure, the structure of the left hooking support sub-mechanism is the same as that of the right hooking support sub-mechanism, and the right hooking support sub-mechanism and the left hooking support sub-mechanism are symmetrically arranged on the left and right sides of the top surface of the lift car. According to the anti-falling elevator, on the basis of the anti-falling function of an existing elevator, the anti-falling performance of the elevator can be further improved, and safety accidents are avoided.

Description

technical field [0001] The invention relates to an elevator, in particular to an anti-fall elevator. Background technique [0002] At present, elevators are widely used in high-rise buildings, and the safety performance of elevators has become one of the most important elevator performances. During the operation of the existing elevators, the elevator may stall due to broken wire ropes, insufficient traction force, or slippage between the wire ropes and the traction sheave grooves, which can easily lead to safety accidents. Most of the existing elevator anti-fall equipment adopts speed governor, safety gear and car buffer. But existing anti-falling device and electric control equipment also often take place out of order phenomenon, cause serious safety accident. Contents of the invention [0003] The object of the present invention is to provide an anti-fall elevator, which can further improve the anti-fall performance of the elevator on the basis of the anti-fall functi...
