A kind of protective groove braking elevator guide rail

Abstract

The invention relates to the field of elevator guide rails, in particular to a protective groove brake elevator guide rail. The protective groove brake elevator guide rail comprises a bottom plate, a wheel groove and a fixing column. The wheel groove and the fixing column distributed in parallel are arranged on the bottom plate. The fixing column is provided with a shelf. A brake column is arranged above the shelf. The brake column penetrates through the fixing column. A push plate is arranged on the shelf. The push plate and the brake column are welded together. A spring is arranged between the push plate and the brake column. The brake column is arranged on the fixing column, the brake column can be arranged on the push plate through the spring, and the automatic restoration effect can be achieved. Besides, the guide rail has the advantages of being convenient to use, easy to operate, good in practicality, low in cost and the like.

Description

technical field [0001] The invention relates to the field of elevator guide rails, in particular to a groove guard braking elevator guide rail. Background technique [0002] With the increasing number of high-rise buildings, the demand for elevators is also increasing. Elevators require safety and reliability, accurate leveling, and comfortable ride. Among them, safety and reliability are the most important performances of elevators. The existing safety devices include safety gears, buffers, etc. When the elevator car stalls and falls, the safety device can reduce the falling speed of the car to a certain extent, and buffer the impact force to achieve the purpose of protecting passengers. The safety device still has some drawbacks. For example, the buffer can only play the role of deceleration buffer when the elevator car squats on the buffer. [0003] In addition, in the prior art, when the elevator guide shoe slides on the surface of the elevator guide rail, the guide ra...

Problems solved by technology

Existing safety devices include such as safety gear, buffers, etc. When the elevator car stalls and falls, the safety device can reduce the falling speed of the car to a certain extent and buffer the impact force to achieve the purpose of protecting the occupants. However, the existing The safety device still has some disadvantages. For example, the buffer will only play the role of deceleration buffer when the elevator car squats on the buffer.

[0003] In addition, in the prior art, when the elevator guide shoe slides on the surface of the elevator guide rail, the guide rail has no sliding restriction on the guide shoe
