Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alignment devices for slab tracks face challenges in maintaining high accuracy and stability, particularly in high-speed rail construction, due to sensitivity to damage, complex adjustment mechanisms, and difficulty in individual rail alignment, which affects the precision and durability of rail alignment.
Innovation Solution
A clamping device with a support block featuring a rail receptacle and lifting units arranged on both sides of the track, allowing for precise alignment and adjustment of rail inclination, with a rigid rail mount and clamping mechanism to secure the rail in place, ensuring stability and ease of handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a swivel bearing mechanism with retaining clips is used to adjust rail inclination, then the angle of attack can be adjusted, but the mounting surfaces of the retaining clips are sensitive to damage and repeated handling makes it impossible to adjust the angle of attack with sufficient accuracy
Solution Approach 1:
The device separates the adjustment function into two independent parts: the rail inclination angle is adjusted once during setup using the bearing mechanism, while the retaining clips only perform the function of securing the rail in position. This segmentation prevents the clips from being damaged by adjustment operations, as they are no longer involved in the adjustment process itself.
Solution Approach 2:
The rail inclination angle is predetermined and set during the initial setup phase before the retaining clips are engaged. The bearing surfaces are pre-positioned at the desired angle, and the clips are simply inserted to lock this pre-established configuration, eliminating repeated handling and damage risk.
2Ease of operation
If lifting spindles are arranged offset from the longitudinal axis of the rail to enable height adjustment, then the rail can be lifted and inclined adjusted, but adjusting one spindle inevitably results in a change in the position of the rail along or around multiple spatial axes, thus complicating alignment
Solution Approach 1:
The device combines multiple lifting spindles with the bearing mechanism into an integrated system where the spindles are positioned to work in conjunction with the pre-configured bearing surfaces. This merging allows height adjustment through the spindles while the bearing mechanism simultaneously maintains the correct inclination angle, preventing unwanted positional changes and simplifying the overall alignment process.
3Device complexity
If a one-piece crossbeam design is used to simultaneously engage and secure both rails, then the device structure is simplified, but the considerable weight and length make it difficult to handle on construction sites
Solution Approach 1:
The device is divided into separate modular components: individual support blocks for each rail, independent lifting spindles, and detachable retaining clips. This segmentation replaces the heavy one-piece crossbeam design, making each component lightweight and easy to handle on construction sites while maintaining the capability to secure both rails through coordinated assembly.
4Stability of the object's composition
If the rail receptacle is designed as a recess in the support block with rigid arrangement between track sections, then the rail position is fixed and stable, but individual adjustment of the angle of attack for only one rail is not possible
Solution Approach 1:
The device incorporates dynamic adjustment capability through the bearing mechanism that allows the rail inclination angle to be modified while the rail remains secured in the recess. The retaining clips are designed to hold the rail firmly during operation but can be easily released to permit angle adjustments, providing both stability during use and adaptability when needed.
