Problems solved by technology

But it brings another problem: during operation, the track will slightly deform outward due to force, or the car will shift horizontally due to unbalanced loads, which are very likely to cause gears and gears to track. Breaking away from the bite, causing the safety problem of the car falling from a high altitude

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0029] It should be noted that when an element is referred to as being “fixed on”, “disposed on” or “installed on” another element, it may be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time; the specific way that one element is fixedly connected to another element can be realized through existing technologies, and will not be discussed here. To repeat it agai...

Abstract

The invention relates to a gear self-driving elevator. The gear self-driving elevator comprises a lift car, an elastic compensation mechanism, two gear driving devices and two toothed guide rails, wherein the top of the lift car is provided with a load bearing transverse beam, and the load bearing transverse beam is provided with a containing cavity of which the two ends are through; the elastic compensation mechanism is arranged in the containing cavity; the two gear driving devices are both connected with the elastic compensation mechanism and can go close to or go away from each other, andthe two gear driving devices are arranged at the two ends of the load bearing transverse beam correspondingly; and the two toothed guide rails are arranged on the two opposite sides of the lift car and are in engagement fit with the two gear driving devices in a one-to-one correspondence mode. The two gear driving devices can be pushed by the compensation capacity of the elastic compensation mechanism to move away from each other, accordingly, the two gear driving devices can be in engagement fit with the two toothed guide rails reliably always, the tooth disengagement problem is avoided, andthe lift car high-altitude falling potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a gear self-driven elevator. Background technique [0002] At present, commonly used elevators mainly use the traction machine to pull the wire rope to drive the car and the counterweight to run vertically and crosswise in the shaft. However, the main disadvantages of this type of traction-driven elevator are that it takes up a lot of space in the shaft, the friction coefficient of the wire rope is not uniform under different working conditions, and it is easily affected by oil pollution, which leads to unstable or even failure of the traction force, and the installation process is complicated due to too many structural components. [0003] In view of this, there is a gear-driven elevator on the market. In this type of elevator, the driving gear fixed on the car roof frame is mated with the gear rails installed on both sides of the vertical shaft, and the car is driven to run ...
