Problems solved by technology
[0003] Although there are multiple anti-falling measures in the elevator, when all the methods fail and the elevator falls, the passengers in the car will be in a state of weightlessness, and will continue to accelerate, and finally hit the bottom with the car at a very high speed, which will easily cause passengers to be paralyzed. fracture, causing injury
There is no better way to avoid this phenomenon at present, and reports of domestic elevator falling injury accidents also occur from time to time.

Embodiment Construction
[0015] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0016] Such as figure 1 , image 3 and Figure 5 As shown, the elevator fall protection self-locking device includes the car 1 and the car guide rail 2 installed in the shaft, and the car guide rail 2 is equipped with a fall brake device 3, which is fixed on the car 1. At the top, the fall arresting device 3 is mainly composed of a lower casing 4, an upper casing 5, a base 6, a driving screw 7 and a brake plate 8, the base 6 is fixed on the car 1, and the lower casing 4 is fixed on the base 6 Upper, the upper housing 5 is fixed on the lower housing 4, the lower ...

The invention relates to an elevator falling protection self-locking device and belongs to the technical field of elevators. The elevator falling protection self-locking device is simple in structure,convenient to use, capable of performing effective braking during elevator falling and large in braking force. According to the adopted technical scheme, the elevator falling protection self-lockingdevice comprises a lift car and lift car guide rails installed in a shaft; and the lift car guide rails are each provided with a falling braking and stopping device. According to the elevator fallingprotection self-locking device, due to the fact that a friction wheel makes contact with the lift car guide rails, a lead screw is driven to push a friction block on a braking plate to be in contact friction with the lift car guide rails through the kinetic energy generated during falling of the lift car, the friction force preventing the lift car from falling is generated, the braking effect is good, running is reliable, the fault rate is low, and the elevator falling protection self-locking device is widely used for falling protection of the elevators.
Description
technical field [0001] The invention relates to an elevator fall protection self-locking device, which belongs to the technical field of elevators. Background technique [0002] With the acceleration of domestic urbanization, the supply of land in cities and towns is becoming increasingly tense, so high-rise buildings also appear in large numbers, among which office buildings, commercial and residential mixed buildings, residential quarters or office buildings are basically equipped with elevators; elevator failures also occur from time to time , There are mainly two types of elevator failures: the one is that the elevator stops running suddenly; the other is that the elevator loses control and falls rapidly. How to protect yourself in the car once you encounter an elevator failure has become a compulsory course: 1. How to call for help when the elevator door fails: The current method is that if the elevator stops suddenly, first of all, don’t panic, try to keep pressing the...
