Staircase portal frame assembling fixture and assembling method thereof

Abstract

The invention relates to a staircase portal frame assembling fixture and an assembling method thereof. The staircase portal frame assembling fixture comprises a portal frame guide rail (7), a portal frame location dolly (10), a station transfer orbit (17), a station transfer dolly (28), a clamping location dolly guide rail (6), an upper clamping location dolly (4) and a lower clamping location dolly (8), and further comprises an upper fixture location base (10), a lower precise hoisting fixture (9), a lower fixture location base (11), a lower portal frame location dolly (10) and a middle portal frame location dolly. The invention further provides an assembling method of the staircase portal frame assembling fixture. The invention fills in a gap in the prior art, solves the bottleneck of assembling the portal frame station, and has the advantages of high degree of automation, high efficiency, high precision and simple and power-saving operation.

Description

technical field [0001] The invention relates to a structure of an escalator gantry assembly tooling and an assembly method thereof, belonging to the escalator category. Background technique [0002] In order to ensure the stability and reliability of the long-term operation of the escalator, reduce the vibration and noise of the escalator, and improve the comfort of the passengers, in the design of the escalator, the main drive, ladder path system, handrail system, front plate positioning bracket, etc. The dimensional design accuracy of the main components is high, and the allowable assembly deviation range is very small, so it is very difficult to control the assembly positioning and accuracy for large-scale equipment-escalators. The traditional escalator assembly method is completed by using the manual hanging wire measurement method. First, the steel wire is used to hang the measurement center line on the escalator truss. While tapping with a hammer to adjust the install...

AI Technical Summary

Problems solved by technology

The main problems of this traditional escalator assembly method are: 1. The factors affected by human beings are large, the precision of component assembly is low, and the quality is unstable; 2. The production efficiency is low and cannot meet the production capacity demand

Comprehensive analysis of these tooling, there are still the following unsolvable problems: 1. The tooling is not universal. The design and manufacture of the tooling needs to be designed and manufactured corresponding to the lifting angle and ladder width of the escalator. The universality of the tooling is poor; 2. The tooling has a single function and can only be used for auxiliary positioning of the ladder road. There is no positioning function of the head glass clamping parts, the front plate bracket and the armrest roller group; 3. There is no automatic detection and adjustment control system, and the errors of parts and tooling will accumulate in the In the assembly parts, the dimensional devia
