Structural Profile Rotator With Side-By-Side Hydraulic Cylinders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing structural profile rotators face issues with hydraulic cylinder maintenance due to piston rod bending, interference between cylinders, and space constraints, limiting versatility and maintenance accessibility.
Innovation Solution
A structural profile rotator design with two blades attached to a spindle, allowing for variable angle adjustment, where one blade is fixed and the other is actuated by a pushing member, and both are rotated by separate devices, reducing interference and facilitating maintenance, with components accessible from the sides and on different horizontal planes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydraulic cylinders are disposed one on top of the other in parallel, then the rotator can achieve the required rotation function, but the piston rods may interfere with each other when bent, hindering normal operation and maintenance
Solution Approach 1:
The patent transitions from a vertical arrangement of hydraulic cylinders (one on top of the other) to a horizontal arrangement (side by side). This dimensional change eliminates interference between piston rods while maintaining the rotator's functional requirements, and significantly improves maintenance accessibility.
2Area of stationary object
If hydraulic cylinders are disposed close to each other, then space occupation is reduced, but maintenance and inspection become difficult requiring withdrawal from track and dismantling of protective cover
Solution Approach 1:
By arranging hydraulic cylinders horizontally side by side rather than vertically stacked, the patent achieves both compact space utilization and improved maintenance accessibility. The side-by-side configuration allows maintenance personnel to access the cylinders without withdrawing the rotator from the track or dismantling the protective cover.
3Volume of stationary object
If dimensions and runs of hydraulic cylinders are restricted to fit within protective cover, then the rotator can be housed within the cover, but this limits the number of components that can be used
Solution Approach 1:
The horizontal arrangement of hydraulic cylinders side by side provides more flexible space utilization within the protective cover. This configuration allows for larger cylinder dimensions and runs without compromising the overall compactness, thereby enabling greater selection of suitable components for different application requirements.

AI summary
Structural profile rotator that can be used with a structural profile conveyor device. The rotator (150) comprises two blades (10,40) attached to a spindle (5) and which define between them a variable angle, comprised for example between 90º and 180º, a pushing member (35) disposed below the first blade (10) and arranged to push the second blade (40) so that it rotates about the spindle (5); and rotation members (80a, 80b), which may be parallel to the second blade (40) arranged to rotate said spindle (5).
