Suspended Conveyor Rail with V-Shape Web for Overload Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension rails for tracks and cranes lack effective overload protection and simple attachment mechanisms, leading to potential failure under extreme loads and inefficient connection of rail sections.
Innovation Solution
A rail design featuring a c-shaped profile head with obliquely extending first web sections forming a V-shape, which enhances overload protection by preventing bending and allows for a positive-locking suspension attachment, along with a profile body that includes angled lower profile walls for additional stiffening and secure weld seam guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the profile head uses a c-shaped design with web sections extending horizontally outwards, then the suspension can be attached using a universal joint, but the rail lacks overload protection and may bend under extreme loads
Solution Approach 1:
The web sections are designed to extend obliquely outwards and upwards at a specific angle (15-35 degrees) rather than horizontally, changing the geometric parameter to provide both suspension attachment capability and overload protection through the V-shaped configuration
2Ease of operation
If the first web sections extend horizontally outwards from the longitudinal center plane, then the suspension attachment is simplified, but the rail profile can bend upwards under extreme overload
Solution Approach 1:
The angle of the first web sections is changed from horizontal to oblique (15-35 degrees), transforming the geometric parameter to prevent upward bending while maintaining suspension attachment functionality
Solution Approach 2:
The V-shaped configuration of the web sections creates a pre-loaded structural arrangement that resists upward bending forces before they occur, providing preliminary anti-action against potential deformation
3Strength
If the web sections are designed to provide overload protection through V-shaped configuration, then the rail gains strength, but the attachment mechanism becomes more complex
Solution Approach 1:
The obliquely extending web sections serve multiple functions simultaneously: they provide the V-shaped configuration for overload protection, create the gap for suspension attachment, and establish the angular geometry for structural stability, thereby achieving multi-functionality without increasing device complexity

AI summary
A rail for suspended conveyors and suspended cranes, having a substantially C-shaped profile head for suspending the rail and a profile body connected thereto. The profile head is open at the top, thereby forming a gap running along a longitudinal center plane bounded on both sides by first web segments extending outward from the center plane. Two second web segments opposite each other and running downward and outward as seen in cross section are connected to the first web segments and the rail is made of two profiles disposed symmetrically about the vertical longitudinal center plane as seen in cross section. The rail supports an overload protection in the region of the profile head, and allows simple attachment by suspension supports. In a particular embodiment the first web segments run diagonally outward and upward and the first web segments are angled relative to the longitudinal center plane.
