Tank Shell Roller Alignment for Circular Welding Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tank fabrication methods face challenges in maintaining the circular cross-section of tank shells during assembly, leading to inefficiencies, increased fabrication time, and reduced quality due to manual alignment processes that are labor-intensive and prone to misalignment.
Innovation Solution
The tank fabricating equipment uses pneumatically or hydraulically actuated rollers that contact the tank shell above and below the horizontal centerline to force the shell into a circular cross-section, aligning adjacent components and facilitating simultaneous rotation for precise welding, eliminating manual alignment errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual alignment processes are used for tank shell assembly, then labor flexibility is maintained, but alignment accuracy deteriorates and fabrication time increases
Solution Approach 1:
The patent replaces manual mechanical alignment processes with an automated mechanical system featuring adjustable arms, rollers, and clamps that automatically position and secure tank shells. This substitution eliminates human error in alignment while maintaining controlled, repeatable positioning, directly resolving the contradiction between alignment accuracy and fabrication time.
Solution Approach 2:
The alignment system is designed to self-adjust and self-position tank shells using its adjustable arms and rollers. The equipment performs its own alignment function without requiring external manual intervention, achieving both high precision and efficiency simultaneously by making the system self-sufficient.
2Productivity
If manual alignment processes are used for tank shell assembly, then equipment complexity is reduced, but productivity deteriorates
Solution Approach 1:
The alignment system is divided into modular components including separate adjustable arms, rollers, and clamps that can be independently positioned and adjusted. This segmentation allows the complex function of tank shell alignment to be achieved through coordinated simple modules, increasing productivity while managing equipment complexity through modularity.
Solution Approach 2:
The alignment equipment is designed with multi-functional arms and rollers that can accommodate different tank shell sizes and configurations. This universality allows a single piece of equipment to perform multiple alignment tasks, increasing overall productivity without proportionally increasing equipment complexity.

AI summary
A design for tank fabricating equipment and system comprises a frame supporting opposing arms for supporting one or more tank shells. The opposing arms pivotally engage opposing sides of the tank shells to force them into a circular cross-sectional shape. The arms are provided with rollers for aligning the tank shell with adjacent components during fabrication. In some embodiments, the rollers are provided with a circumferential channel to accommodate welding seams and to ensure alignment of butt joints.
