An elevator guide rail

Abstract

The invention discloses an elevator guide rail, which comprises a guide rail, a fixed seat and a fixed plate. An elevator car body is arranged on one side of the outer surface of the guide rail, and a second threaded hole is provided on the outer surface of the lower end of the fixed seat close to one side. , the internal thread of the second threaded hole is connected with a screw, the upper surface of the fixed seat is fixedly connected with a fixed block, and a chute is provided inside the fixed block near the upper end, and one side of the chute is set There is a spring, the outer surface of the other side of the chute is provided with a first threaded hole, the inside of the first threaded hole is threadedly connected with a threaded rod, and the inside of the chute is slidably connected with a slider between the spring and the threaded rod, The device fixes the lubricating device and the fixing block on the upper end of the elevator car, and the lubricating device with U-shaped structure can be well engaged on both sides of the guide rail, so that it can be wiped and lubricated when the elevator is running. Oil maintenance, improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of elevator guide rail devices, in particular to an elevator guide rail. Background technique [0002] The elevator guide rail includes a guide rail body and mounting ears located on both sides of the guide rail body, and is an elevator component composed of steel rails and connecting plates. From the cross-sectional shape, it can be divided into three types: T-shape, L-shape and hollow. While the guide rail plays a guiding role, it also bears the impact force of the car and elevator braking, and the impact force of the safety gear during emergency braking. [0003] 1. Due to the humid and dark environment of the elevator shaft, the surface of the existing elevator guide rails will produce a certain degree of rust after long-term use, so it is necessary for the staff to stop the machine regularly for maintenance and apply lubricating oil, but the maintenance of the existing elevator guide rails is time-cons...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the humid and dark environment of the elevator shaft, the surface of the existing elevator guide rails will produce a certain degree of rust after long-term use, so it is necessary for the staff to stop the machine regularly for maintenance and apply lubricating oil, but the maintenance of the existing elevator guide rails is time-consuming It is laborious and requires workers to work on heights, making it dangerous;

[0004] 2. At the same time, in the maintenance of the existing elevator guide rail, the elevator needs to be stagnated for a long time, which is not convenient for the owner to use; for this reason, a kind of elevator guide rail is proposed

[0005] 3. Since the elevator shaft is closed for a long time, it will cause spider webs between the elevator shaft and the guide rail. For a long time, it will affect the rotation of the roller, and it will also affect the lubrication of the guide rail. At the same time, if there is rust on the guide rail, it will affect the lubrication effect of the lubricating oil.
