Wedge Level Adjusters for Rotary Machine Support Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing rotary machines cannot adjust the levelness of the machine by modifying the support legs once they are fixed to the rotary machine main body, necessitating adjustment of the support legs with respect to the base plate.
Innovation Solution
A method involving wedge-shaped level adjusting members placed on the base plate to adjust the horizontal level of support legs, allowing for reliable level adjustment by adjusting the pushing amounts of these members, and subsequent welding to fix positions, enabling easy and precise level adjustment of the rotary machine main body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If support legs are fixed to the rotary machine main body before installation, then the structural integrity and stability are improved, but the ability to adjust levelness is lost
Solution Approach 1:
The support leg assembly is segmented into three distinct components: the support leg itself, the level adjusting member, and the fixing member. This segmentation allows the level adjusting member to be positioned between the support leg and base plate, enabling levelness adjustment while maintaining structural integrity through the fixing member.
Solution Approach 2:
The level adjusting member is installed in advance between the support leg and base plate before final fixation. This preliminary action allows levelness to be adjusted during installation, and once the desired level is achieved, the fixing member secures all components together, preventing further adjustment but maintaining the achieved levelness.
2Ease of operation
If support legs are adjusted by modifying their position or height with respect to upper end portions, then levelness adjustment is possible, but the support legs must be separated from the rotary machine main body
Solution Approach 1:
The level adjusting member acts as an intermediary component positioned between the support leg and the base plate. This mediator enables levelness adjustment by allowing controlled movement and positioning, while the fixing member subsequently secures the assembly, maintaining structural integrity without requiring separation from the rotary machine main body.
3Manufacturing precision
If the positions of support legs are adjusted with respect to the base plate to ensure levelness, then levelness can be maintained, but the installation process becomes more complex
Solution Approach 1:
The level adjusting member incorporates a wedge-shaped structure that changes the geometric parameters of the support leg assembly. By inserting or removing the wedge-shaped level adjusting member, or adjusting its position, the height and angle parameters of the support leg can be precisely controlled, enabling accurate levelness adjustment.
Solution Approach 2:
The level adjusting member provides dynamic adjustment capability during installation, allowing the support leg height to be modified as needed. Once the desired level is achieved, the fixing member transforms the system from a dynamic (adjustable) state to a static (fixed) state, securing the achieved configuration.

Function Achieved in This Case
This method ensures easy and reliable level adjustment of the rotary machine main body by allowing horizontal level adjustment of the support legs, improving work efficiency and reducing costs by allowing reuse of the base plate without reinstallation.
