Energy Storage Cabinet Lifting Structure to Protect Beam-Column Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection between columns and beams in energy storage cabinets often breaks during lifting due to uneven distribution of forces, leading to damage.
Innovation Solution
A lifting assembly with a lifting plate and hole is connected to each column, allowing the hook of a lifting machine to engage the hole, distributing forces to prevent breakage by ensuring the column bears the majority of the load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lifting assembly is connected to the beam to facilitate lifting, then the handling of the energy storage cabinet is facilitated, but the connection between the column and the beam breaks during lifting
Solution Approach 1:
The lifting assembly is moved from the beam to the column, using the column as an intermediary structure that is specifically designed to bear lifting loads. The column acts as a mediator that transfers the lifting force directly to the ground through its vertical structure, preventing force transmission through the beam-column connection joints.
Solution Approach 2:
The lifting function is segmented and assigned to specific columns rather than being distributed across the entire beam structure. Each column independently handles lifting loads, separating the lifting function from the beam's primary function of providing horizontal support and connection between columns.
2Reliability
If the lifting assembly is connected to the column to prevent connection breakage, then the connection between column and beam remains intact, but the column is subjected to larger force
Solution Approach 1:
Instead of trying to strengthen the beam-column connection to handle lifting forces, the solution inverts the approach by directly connecting the lifting assembly to the column. This reverses the force transmission path, allowing the column to directly bear the lifting load without relying on the beam connection, thereby protecting the connection from breakage.
3Reliability
If multiple lifting assemblies are connected to columns, then the energy storage cabinet can be lifted safely, but the device complexity increases
Solution Approach 1:
The columns serve multiple functions: they provide structural support for the cabinet framework, serve as mounting points for lifting assemblies, and directly bear the lifting loads. This multi-functionality reduces the need for separate dedicated lifting structures, thereby limiting the increase in device complexity.
