Rotating Machine Support Platform for Level Load Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In rotating machines supported by a base plate and a column, the jack bolt's position away from the column leads to an uneven distribution of load, causing the base plate to incline and creating a gap between the machine and the column, necessitating high-accuracy installation.
Innovation Solution
A supporting platform with a pair of separated supporting bodies, a supporting column, outer adjustment members, and inner adjustment members that act on both sides of the load to prevent inclining, allowing for precise height and level adjustments without increasing stiffness, and using curable fillers to secure the platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the jack bolt is provided at a position separated horizontally from the supporting column, then the jack bolt does not interfere with the supporting column, but the base plate becomes inclined and the supporting column becomes inclined, generating a gap between the rotating machine and the upper end surface of the supporting column
Solution Approach 1:
The supporting body is divided into an upper plate section and a lower plate section connected by a connection section. The outer adjustment member is positioned at the outer side of the connection section while the inner adjustment member is positioned at the inner side, creating a segmented adjustment system that distributes load support across multiple points rather than relying on a single jack bolt positioned far from the column.
Solution Approach 2:
The connection section acts as an intermediary element between the upper plate section and lower plate section, positioned to overlap with the supporting column. This intermediary structure transmits and distributes the load from the upper plate section through the connection section to the lower plate section, preventing direct transmission of inclined forces that would cause column inclination.
2Manufacturing precision
If the jack bolt is provided close to the supporting column, then the load distribution is improved, but the jack bolt interferes with the supporting column
Solution Approach 1:
The supporting body is segmented into upper and lower plate sections with a connection section between them. This segmentation allows the structure to achieve good load distribution through the vertically aligned upper plate section - connection section - lower plate section path, while the outer adjustment member is positioned away from the column to avoid interference.
Solution Approach 2:
The adjustment members are positioned in different spatial dimensions relative to the supporting column. The outer adjustment member is positioned horizontally outside the connection section, while the inner adjustment member is positioned inside the connection section. This spatial arrangement allows both members to function without interfering with the vertically extending supporting column.
3Manufacturing precision
If the stiffness of the upper plate section is increased to prevent inclining, then the load distribution is improved, but the device complexity and cost increase
Solution Approach 1:
The connection section serves as an intermediary element positioned to overlap with the supporting column when viewed in the vertical direction. This intermediary structure provides a stable load transmission path from the upper plate section to the lower plate section, preventing upper plate section inclining without requiring increased stiffness of the upper plate section itself.
Solution Approach 2:
The load support function is extracted from the upper plate section itself and transferred to the adjustment members and connection section. Instead of relying on the upper plate section's stiffness to prevent inclining, the system uses the outer and inner adjustment members positioned on both sides of the connection section to support the load, thereby preventing inclining without increasing upper plate section stiffness.

AI summary
A supporting platform which supports a rotating machine on a base, includes: a pair of supporting bodies which is provided on the base to be separated from each other in a horizontal direction; a supporting column which is provided on the supporting body, extends upward in a vertical direction, and supports a supporting target portion provided in the rotating machine; an outer adjustment member which supports the supporting body on the base and adjusts a height of the supporting body with respect to the base; and an inner adjustment member which is disposed inside the outer adjustment member in a separation direction of the pair of supporting bodies, supports the supporting body on the base, and adjusts the height of the supporting body with respect to the base.
