Rolling Stand Exchange Carriage With Independent Lifting Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stand-changing carriages for rolling stands require complex stand-supporting mechanisms and are inefficient in safely and quickly moving rolling stands between the rolling mill and the stand workshop.
Innovation Solution
A stand exchange carriage with individual stand positions and a lifting mechanism that allows for independent raising and lowering of rolling stands, eliminating the need for complex stand-supporting mechanisms and enabling safe, flexible transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex stand-supporting mechanism is used to push and pull rolling stands onto and from the carriage, then the rolling stands can be transported, but the device complexity increases and the carriage must move very close to the support
Solution Approach 1:
The patent extracts the lifting function from the stand-supporting mechanism and assigns it to a dedicated lifting mechanism on the carriage. This separates the transport function (performed by the carriage) from the support function (performed by the stand support), eliminating the need for the support mechanism to perform complex pushing and pulling operations.
Solution Approach 2:
The lifting mechanism acts as an intermediary between the stand support and the rolling stands. Instead of the stand support directly manipulating the rolling stands through complex pushing/pulling mechanisms, the lifting mechanism mediates by independently raising and lowering the stands at each position, simplifying the interaction.
2Ease of operation
If the carriage moves close to the support to allow the movement mechanism to maneuver rolling stands, then stands can be transferred, but the operational flexibility and speed are reduced
Solution Approach 1:
The patent segments the stand transfer process into independent lifting operations at each stand position. Instead of requiring a single complex maneuver that brings the carriage close to the support, each position can independently lift and release stands, allowing for faster and more flexible operations.
Solution Approach 2:
The lifting mechanism provides dynamic control over each stand position independently. The carriage can adjust the lifting operation at each position based on real-time requirements, enabling faster stand changes without requiring the carriage to maintain a fixed close position to the support throughout the entire operation.
3Productivity
If multiple rolling stands are transported simultaneously, then productivity increases, but the carriage must accommodate multiple stands requiring coordinated lifting
Solution Approach 1:
The carriage is divided into multiple independent stand positions, each with its own lifting mechanism. This segmentation allows each position to operate independently, enabling simultaneous transport of multiple stands without requiring complex coordinated control, as each position can lift and release stands autonomously based on local requirements.
