Railroad Rail Support With Segmented Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing railway rail supports complicate maintenance and positioning adjustments, as loosening the anchoring element for rail movement leads to loss of transverse wedging, increasing maintenance duration and complexity, especially during rail replacements.
Innovation Solution
A support system with separate functions for clamping and transverse wedging, featuring oblong openings for easy adjustment and anchoring, allowing independent movement and repositioning of the rail without disassembling the support, facilitated by distinct upper bearing surfaces and receiving portions for anchoring and fastening elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the anchoring element is loosened to allow lateral movement of the support for rail position adjustment, then the rail can be repositioned, but the support loses its transverse wedging and stability
Solution Approach 1:
The patent divides the single opening into two separate openings: a first opening for the anchoring element and a second opening for the fastening element. This segmentation allows the anchoring element to remain engaged and maintain transverse stability while the fastening element is loosened for rail position adjustment, resolving the contradiction between ease of operation and reliability.
2Ease of repair
If the anchoring element is completely loosened to detach the elastic fastener for rail replacement, then the rail can be freed from the support, but the support becomes free to move laterally causing alignment loss
Solution Approach 1:
By separating the anchoring function from the fastening function into two distinct openings, the anchoring element can remain engaged to prevent lateral support movement while the fastening element is loosened for rail replacement. This maintains transverse alignment accuracy throughout the repair process.
Solution Approach 2:
The anchoring element is预先 engaged and maintains the support's transverse position before the rail replacement begins. This preliminary action ensures that when the fastening element is loosened and the rail is replaced, the support remains stable and aligned, eliminating the need for realignment after replacement.
3Device complexity
If a single opening is used for both anchoring and fastening, then the structure is simpler, but maintenance procedures are lengthened and complicated
Solution Approach 1:
The patent segments the single opening into two separate openings with distinct functions. This increases structural complexity slightly but dramatically improves maintenance efficiency by allowing independent access to anchoring and fastening elements, enabling faster rail replacements without complete disassembly.

AI summary
Railroad rail support, of the type having an elastic clip in which said clip bears against a foot of said rail and is tensioned by screwing in an anchoring element such as a screw spike or a stud bolt, this railroad rail support comprising a lateral wedging surface (15), a first upper bearing surface (32), a second upper bearing surface (26) distinct from the first upper bearing surface (32), a first opening (33) that is of oblong cross section and opens at the first upper bearing surface (32) and passes vertically through the support (10), a second opening (27) that opens at the second upper bearing surface (26), and a receiving portion (20) that is configured to receive a railroad clip (50) which is provided at least laterally outward with respect to the second opening (27).
