Loading Platform Wheel Height Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting the height positioning of vehicles on loading platforms, such as railway wagons, are not adaptable to all types of wagons and require lifting means or are not designed for secure immobilization of wheels, limiting their effectiveness in maintaining a constant height relative to the platform.
Innovation Solution
A system comprising recesses in the loading platform and mobile, deformable support devices that adjust the wheel height by varying the contact zone, allowing for secure immobilization and adaptation to different wheelbases and wear states, using wedges or flexible parts with tensioning devices for precise height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If vertical wedges are placed between the pocket and end assemblies to adjust height, then the lower part of the pocket can be positioned at a constant low level, but this method is not suitable for all types of railway wagons and requires suitable handling means to lift the ladle
Solution Approach 1:
The loading platform is segmented into a movable part and a fixed part, allowing independent adjustment of the movable platform to accommodate different wagon types and achieve precise height positioning without requiring complete redesign for each wagon type
Solution Approach 2:
The adjustable loading platform system serves multiple functions: it adapts to different wagon types, positions vehicles at optimal heights for loading/unloading, and maintains constant distance from the ground, eliminating the need for separate solutions for each wagon type
2Reliability
If removable chocks are used to immobilize wheels on a car carrier vehicle, then the wheels can be secured, but these chocks are not designed to adjust the height of vehicles and are generally not used in pairs
Solution Approach 1:
The invention merges the wheel immobilization function with the height adjustment function into a single integrated system. The movable loading platform simultaneously secures vehicles and adjusts their height position, eliminating the need for separate chocks and lifting equipment
Solution Approach 2:
The system uses the vehicle's own weight on the movable loading platform to achieve both immobilization and height adjustment automatically, without requiring external lifting means or additional securing devices
3Ease of operation
If a mobile lifting central floor is used to circulate vehicles at the same height as the ends of the rolling frame, then vehicles can be loaded, but this system does not provide individual adjustment in height of the wheels
Solution Approach 1:
The loading platform is divided into movable and fixed segments, allowing individual adjustment of each vehicle's position on the movable platform to achieve precise wheel height alignment while maintaining overall platform functionality for vehicle circulation
Solution Approach 2:
The movable loading platform can dynamically adjust its position and orientation to accommodate different vehicle heights and wheelbases, providing individualized height adjustment for each vehicle while maintaining the ability to circulate vehicles during loading operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables optimal and constant distance between the ground and the lowest part of the vehicle, secure immobilization of wheels, and adjustment of the vehicle's height relative to the platform without lifting means, accommodating various wagon types and load conditions.
Implementation Method 1
the support device comprising at least one mobile and/or deformable support part intended to support the wheel by at least one contact zone so that the wheel is carried by said contact zone at the level of the recess, the displacement or the deformation of the at least one support piece vertically displacing the position of the contact zone
Implementation Method 2
In a first variant, within each pair of shims, the at least one contact zone is composed of an oblique support and wedging surface on each shim
