Tunnel Light Column Alignment via Limiting Measuring Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing light columns in tunnel media systems often result in inclination due to staggered installation holes in beam steel angles, affecting the viewing experience for passengers.
Innovation Solution
A method involving the use of a limiting measuring tool with non-circular limiting columns to ensure that installation holes in upper and lower beam steel angles are in the same vertical plane, combined with horizontal measuring tools to maintain consistent distances between adjacent beam steel angles, and assembly plates for precise positioning and connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If beam steel angles are fixedly connected to the adjustable support using conventional methods, then the installation process is simple, but the installation holes in the upper and lower beam steel angles may become staggered, causing the light columns to incline
Solution Approach 1:
A positioning plate is introduced as an intermediary component between the adjustable support and the beam steel angles. The positioning plate features positioning holes that precisely align with the installation holes of both upper and lower beam steel angles, ensuring they are in the same vertical plane. This mediator component transfers and maintains the precise alignment relationship during the installation process, eliminating the inclination problem while keeping the overall installation process straightforward.
2Productivity
If the installation holes in upper and lower beam steel angles are not in the same vertical plane, then the installation process can proceed without complex positioning, but the installed light columns will incline, affecting the watching effect
Solution Approach 1:
The positioning holes in the positioning plate are pre-configured to ensure that when the positioning plate is installed on the adjustable support, the installation holes of the upper and lower beam steel angles are automatically aligned in the same vertical plane. This preliminary positioning action is performed before installing the beam steel angles and light columns, ensuring vertical alignment reliability is built into the installation process from the beginning, without requiring complex adjustments during installation.

AI summary
The present disclosure relates to an installing and positioning method for light columns of a tunnel media system, and relates to the field of tunnel media system installation. The installing and positioning method comprises the following steps: S1, installing an adjustable support; S2, installing beam steel angles, forming installation holes in each beam steel angle at intervals along the length direction of each beam steel angle, firstly installing one beam steel angle on a connecting plate on the upper side of the adjustable support, then placing the other beam steel angle on a connecting plate on the lower side of the adjustable support, and clamping the upper ends and the lower ends of limiting measuring tools in the installation holes in the corresponding positions of the upper and lower beam steel angles respectively in which the limiting measuring tools are perpendicular to the two beam steel angles at the same time, and finally fixing the position of the second beam steel angle on the adjustable support; S3, sequentially installing the rest of the beam steel angles on the adjustable support; and S4, installing the light columns at the installation holes at the corresponding positions of the upper and lower beam steel angles. According to the installing and positioning method, the installation holes in the corresponding positions of the two installed beam steel angles can be located in the same vertical plane, and the probability that the installed light columns incline is reduced.
