Adjustable Guide Roller Carriers for Cooling Tower Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional service access systems for cooling towers face challenges in adapting to varying wall contours and thicknesses, requiring complex conversion work to ensure even contact of guide rollers with the building wall, especially for convexly curved or oval shapes, leading to inefficient renovation processes.
Innovation Solution
The system incorporates adjustable carriers and guide rollers, including diagonal supports of adjustable length and pivotable elements, allowing for fine adjustments and stable contact with the building wall, enabling simple conversion to match the wall's dimensions and contours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional welded superstructure designs are used, then structural stability is achieved, but adaptability to varying wall contours and thicknesses deteriorates, requiring complex conversion work
Solution Approach 1:
The base support is divided into modular sections with standardized connection interfaces. The guide roller supports are segmented and can be independently adjusted along the base support length, allowing the structure to adapt to varying wall contours without requiring complete redesign or complex conversion work.
Solution Approach 2:
The guide roller supports are made adjustable rather than fixed, enabling dynamic repositioning along the base support. This allows the superstructure to adapt to different wall thicknesses and contours by simply repositioning components rather than performing complex conversion work, while maintaining structural stability through standardized connections.
2Manufacturing precision
If fixed-position guide rollers are used, then structural simplicity is maintained, but manufacturing precision of wall contact deteriorates when wall thickness varies
Solution Approach 1:
The guide roller supports are designed to be adjustable along the base support rather than fixed in position. This allows precise positioning of guide rollers to match actual wall thickness and contour variations, improving contact precision without requiring complex mechanisms—only simple repositioning of modular components.
Solution Approach 2:
The position parameter of guide roller supports can be changed along the base support length according to measured wall thickness and contour. This allows the system to adapt to varying wall dimensions by adjusting the support position parameter, achieving precise contact without increasing structural complexity.
3Productivity
If the superstructure is designed for specific wall dimensions, then initial installation is simplified, but productivity deteriorates when renovating different wall sections requiring conversion work
Solution Approach 1:
The base support and guide roller support system is designed with universal adjustability, allowing the same modular components to serve multiple wall sections with different thicknesses and contours. This eliminates the need for conversion work between different wall sections, significantly improving renovation productivity while maintaining ease of assembly through standardized interfaces.
Solution Approach 2:
The adjustable guide roller supports enable the superstructure to dynamically adapt to different wall sections during renovation. Instead of requiring conversion work for each new wall section, the system can simply reposition the guide rollers along the base support, maintaining high productivity and avoiding downtime for structural modifications.

This design allows for easy adaptation of the upper carriage to the wall's contour, ensuring stable and efficient renovation by allowing for precise positioning and contact of guide rollers, reducing the need for extensive conversion work and enabling top-to-bottom processing of wall sections without conversion.
Implementation Method 1
a plurality of running wheels (2) mounted on the base support (1), via which the base support (1) can be movably supported on the upper side of a building wall
Implementation Method 2
Carry guide rollers (4), which are assigned to the inner and outer side surfaces of a building wall, in order to support the base support (1) on the side surfaces

AI summary
The superstructure has multiple running wheels (2) mounted at a base beam (1) i.e. I-beam. The base beam is movably supported at an upper side of a cooling tower wall (K) by the wheels. Carriers (5-7) downwardly protrude from the base beam on both sides of the wheels, and carry guide rollers (4). The carriers are associated to inner and outer side surfaces of the tower wall for supporting the base beam at the side surfaces. One of the associated carriers is adjustably attached at the base beam, and fastened in a longitudinal extension of the base beam in different positions.
