Mobile Bridge Tower Maintenance Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintenance of bridge towers is challenging due to their height, exposure to harsh weather conditions, and the need for extensive scaffolding that is costly and time-consuming to install and uninstall, leading to traffic delays and increased maintenance time.
Innovation Solution
A bridge tower apparatus comprising a first and second platform supported by upper and middle support beams, with a cable system and spring-loaded wheel for vertical movement along the tower shaft, allowing efficient deployment and stability in windy conditions, reducing the need for extensive scaffolding and enabling quicker maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stationary scaffolding is attached alongside the tower to support workers and equipment, then workers can perform maintenance on the tower, but the scaffolding is expensive to build and install, and the time to install and uninstall it delays maintenance
Solution Approach 1:
The patent applies the dynamics principle by transforming the traditional stationary scaffolding into a mobile platform that can move vertically along the tower shaft. The platform is equipped with wheels that engage with the tower shaft and a cable system for vertical movement, allowing it to dynamically reposition to different maintenance locations rather than remaining fixed in one position.
Solution Approach 2:
The patent applies segmentation by dividing the maintenance system into modular components: a movable platform, support beams, cable systems, and wheel assemblies. This modular structure allows the platform to be transported to the bridge site, assembled around the tower shaft, and easily disassembled after use, significantly reducing installation and uninstallation time compared to traditional stationary scaffolding.
2Adaptability or versatility
If scaffolding extends to the bottom of the tower beneath the surface of the water to support workers, then complete tower coverage is achieved, but the additional scaffolding below water surface is expensive to build and install
Solution Approach 1:
The mobile platform can be vertically positioned at any height along the tower shaft above the water surface, providing adaptable coverage where maintenance is actually needed. Workers can move the platform to different elevations as maintenance progresses, eliminating the need for permanent scaffolding structure extending below the water surface.
Solution Approach 2:
The system changes the parameter of platform position from fixed to variable, allowing the platform to be moved to different vertical locations along the tower shaft. This parameter change enables complete tower coverage above water without requiring additional scaffolding material extending below the water surface.
3Reliability
If wind speeds are greater than 40 mph, then workers cannot perform maintenance due to jostling scaffolding, but extending maintenance windows requires completing work faster
Solution Approach 1:
The mobile platform with wheel engagement and cable suspension provides a more stable configuration that can better withstand wind loads compared to traditional scaffolding. The system can be dynamically adjusted and secured at different positions, maintaining stability during maintenance operations even in windy conditions, thereby allowing work to proceed without strict wind speed limitations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus allows for quick and efficient maintenance by supporting workers and equipment along the tower shaft, reducing traffic delays and maintenance time while withstanding high wind loads and tapering tower shafts, using less material than traditional scaffolding.
Implementation Method 1
a wheel and a spring urging the wheel from the scaffolding to a bridge tower shaft
Implementation Method 2
a cable attached to the upper support beam. The cable may be arranged to vertically move the scaffolding
