A method for connecting and fixing elevator guide rails

Abstract

The invention discloses a connection assembly for elevator guide rails and a connection fixing method for the elevator guide rails. By means of the T-shaped seal type hollow guide rails, structural strength is correspondingly increased compared with traditional hollow guide rails. The connection assembly is arranged between two adjacent sections of the guide rails, and the connection assembly is arranged on the inner sides of the guide rails to guarantee glancing flatness between the guide rails. The connection assembly is of a U-shaped structure, compressive strength on two sides of each guide rail is effectively enhanced, deformation of each guide rail is reduced, and service life of each guide rail is prolonged. In addition, the guide rails are formed in a cold roll forming joint automatic oxy-arc welding and water cooling mode, labor intensity of workers is lowered compared with manual electric welding, and production efficiency is improved. Water cooling and automatic shaping are conducted, forming quality of the guide rails is guaranteed, the strength is better than that of common opening seal hollow rails, a galvanized sheet technology is utilized, follow-up galvanization is omitted, and more environment-friendly use of a product is achieved. Compared with the traditional opening type hollow rails, the connection assembly is characterized in that guide surfaces of the guide rails are wider, an elevator operates more stably, and noise is lower.

Description

technical field [0001] The invention belongs to the technical field of elevator track processing and manufacturing, and in particular relates to a connecting assembly for an elevator guide rail and a connection and fixing method for the elevator guide rail. Background technique [0002] At present, with the increasing number of high-rise buildings, the demand for high-speed elevators is gradually increasing. The elevators manufactured by most elevator manufacturers in my country are of the guide rail type, that is, the car runs along the fixed guide rails during the operation of the elevator. run. [0003] The elevator guide rail is a safe rail for the elevator to run up and down in the well. The guide rail is installed on the well wall, and is fixedly connected to the well wall by the guide rail frame and the guide rail bracket. The guide rails commonly used in elevators are "T"-shaped guide rails. This type of guide rail has the characteristics of strong rigidity, high re...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the problem that the external connection between the elevator guide rails connected in series in the prior art affects the straightness of the two rails after the series connection, and the traditional hollow guide rail is open type, the structural strength is poor, and its guide surface is relatively thick. narrow, easy to generate noise when the elevator is running, and the elevator is unstable. Increase the structural strength, increase the width of the guiding surface of the guide rail, realize the smooth operation of the elevator, reduce the noise, and ensure the straightness of the elevator when it is connected in series
