Road Trailer-to-Bogie Coupling by Horizontal Transshipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming trains by coupling road trailers with bogies require a vertical lift, which is technically complex, energy-intensive, and time-consuming, and can lead to high load peaks on bogies and connecting elements.
Innovation Solution
A method using a horizontal transshipment system with a loading device that moves transversely to the track direction, allowing road trailers to be coupled to bogies through a relative movement in the track direction, eliminating the need for vertical lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If vertical lift coupling method is used to couple road trailers with bogies, then coupling can be achieved, but technical complexity increases and energy consumption increases
Solution Approach 1:
Instead of lifting the road trailer vertically to couple with the bogie (conventional method), the invention inverts the approach by having the bogie horizontally approach and couple with the road trailer at ground level. The loading device moves the bogie horizontally along the track toward the stationary road trailer, eliminating the need for vertical lifting mechanisms.
Solution Approach 2:
The invention transitions from vertical coupling (one dimension) to horizontal coupling (another dimension). By moving the coupling action from the vertical dimension to the horizontal dimension, the system eliminates complex vertical lift mechanisms while maintaining effective coupling capability.
2Ease of manufacture
If vertical lift coupling method is used to couple road trailers with bogies, then coupling can be achieved, but energy expenditure increases
Solution Approach 1:
The invention inverts the conventional coupling approach by having the bogie move horizontally to couple with the road trailer, rather than lifting the road trailer vertically. This inversion eliminates energy-intensive vertical lifting while maintaining coupling effectiveness.
Solution Approach 2:
By shifting the coupling action from the vertical dimension to the horizontal dimension, the system avoids the high energy expenditure associated with lifting heavy loaded trailers (up to 40 tonnes) vertically, utilizing instead the lower-energy horizontal movement capability of the loading device.
3Ease of manufacture
If vertical lift coupling method is used to couple road trailers with bogies, then coupling can be achieved, but coupling time increases
Solution Approach 1:
The invention inverts the coupling sequence by having the bogie approach the road trailer horizontally and couple at ground level, rather than lifting the trailer vertically. This inversion enables faster coupling by eliminating the time-consuming vertical lift and lower operations.
Solution Approach 2:
By performing coupling in the horizontal dimension rather than vertical, the system achieves faster operation since horizontal movement and coupling can occur more rapidly than vertical lifting operations, reducing overall coupling time.
4Strength
If vertical lift coupling method is used to couple road trailers with bogies, then coupling can be achieved, but load peaks on bogies and connecting elements increase
Solution Approach 1:
The invention inverts the coupling approach by having the bogie move horizontally to connect with the road trailer, rather than lowering the trailer vertically onto the bogie. This inversion eliminates the impact loads and load peaks that occur during vertical lowering, distributing forces more evenly throughout the coupling process.
Solution Approach 2:
By transitioning from vertical to horizontal coupling, the system avoids the high impact forces and load peaks associated with vertical lifting and lowering operations. Horizontal coupling allows for controlled, gradual connection without the sudden load peaks that occur when heavy trailers are lowered onto bogies.
