Preparing method of elevator guide rail

Abstract

The invention discloses a preparing method of an elevator guide rail. The preparing method of the elevator guide rail comprises the steps that profiles are subjected to destressing treatment, the profiles are placed in the outdoor natural environment to be stacked together in a flat manner, the duration is seven to ten days, and through wind blowing and sunlight drying under the natural condition,the profiles with stress removed are obtained; the obtained profiles with the stress removed are subjected to rust removal treatment, the profiles are placed in a shot blasting machine, composite metal shots with the granularity of phi 2.5 to phi 1 mm are adopted, compressed air serves as power, high-speed motion of the composite metal shots is used for cleaning and rust removal of the profile surfaces, the duration is controlled within 5 to 20 minutes, and the profiles obtained after rust removal can be obtained; and the profiles obtained after rust removal are subjected to rough machining treatment, the profiles are fed into a straightening machine to be straightened, the straightening speed is 2 to 4m / s, and the profiles obtained after roughening can be obtained. According to the preparing method of the elevator guide rail, through the small symmetry tolerance of a male tenon and a female tenon, when the elevator guide rail is used, the guide rail is more stable and comfortable, and meanwhile in long-time use, the anti-corrosion effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical devices, in particular to a method for preparing elevator guide rails. Background technique [0002] Elevator guide rail is an elevator component composed of steel rails and connecting plates. It is divided into car guide rails and counterweight guide rails. Elevator guide rails are two or more vertical or inclined rigid rails installed in the elevator shaft or between floors. Ensure that the car and the counterweight device move vertically up and down along it, ensure that the steps of the escalator and moving walkway move along it inclined or horizontally, and provide guidance for the elevator car, reloading device or steps. The guide rail not only controls the elevator car and The running track of the counterweight is also a solid support for emergency braking when the car accidentally overspeeds, so the elevator guide rail is an important part related to the elevator's running quality and e...

Problems solved by technology

[0003] However, there are certain disadvantages in the preparation of the elevator guide rails. The existing elevator guide rails are not finely calibrated or manually fine-tuned, so that there are errors in the manual calibration of the elevator guide rails, so that the quality of the elevator is poor during operation, and it is unstable. To this end, we propose a preparation method for elevator guide rails
