Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing goods handling devices for combined freight transport face challenges in easily, reliably, and efficiently raising and lowering wagon attachments from freight wagons to rail systems, requiring improved mechanisms for transverse transport.
Innovation Solution
The introduction of a shuttle beam with a lifting mechanism that includes a wedge lifting device, allowing for synchronized movement of lifting carriages and rollers to raise and lower the lifting beam, enabling efficient transfer of wagon attachments between wagon underframes and loading tracks, with the shuttle beam being driven by electric motors and spindles, and featuring a compact design for reduced construction height and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lifting devices are fixed to the track bed, then the lifting function is stable and reliable, but the device complexity and construction height increase
Solution Approach 1:
The lifting device is integrated into the shuttle beam structure, merging the lifting function with the transport beam. The lifting carriages are mounted on the shuttle beam itself rather than being separate fixed installations, combining transport and lifting capabilities in one mobile unit.
Solution Approach 2:
The lifting device transitions from a static fixed installation to a dynamic mobile system. The shuttle beam with integrated lifting carriages can move along the track, providing lifting capability at different positions without requiring fixed lifting points throughout the entire track length.
2Productivity
If a wedge lifting device with synchronized lifting carriages is used, then the lifting efficiency and reliability improve, but the device complexity increases
Solution Approach 1:
The wedge-shaped lifting beam acts as an intermediary mechanism between the lifting carriages and the wagon attachment. The wedge geometry converts the horizontal movement of lifting carriages into vertical lifting motion, providing mechanical advantage and synchronized lifting without complex control systems.
Solution Approach 2:
The lifting process uses periodic reciprocating motion of the lifting carriages along the wedge surfaces. The carriages move horizontally along the inclined wedge faces, converting linear horizontal motion into vertical lifting motion through the wedge geometry, creating a rhythmic lift-maintain-lower cycle.
3Length of stationary object
If the shuttle beam design is made compact, then the construction height and cost are reduced, but the lifting capacity and reliability may be compromised
Solution Approach 1:
The lifting mechanism transitions from vertical stacking (increasing height) to horizontal expansion (increasing length). The wedge-shaped lifting beam with carriages moving along inclined surfaces achieves lifting capacity through horizontal movement rather than vertical stacking, reducing construction height while maintaining reliability.
