Rail-Mounted Work Unit With Detachable Transport Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for track-bound work, such as rail track construction, face challenges in efficient transportation to and from the site of use, particularly for locations inaccessible by rail.
Innovation Solution
A transport unit is designed that can be detachably fastened to a rail vehicle, allowing for rail transport and also accommodating low-loader or ship transport, with adjustable components to reduce space during transport and standard container dimensions for low-cost shipping, incorporating lifting arms, rail adjustment devices, and other work equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices are designed as custom-made rail-mounted products, then the rail bed is not affected and the device can be transported to and from the railroad, but the device cannot reach workplaces that cannot be accessed by rail
Solution Approach 1:
The device is divided into a working unit and a transport unit that can be detachably connected. The transport unit can be separated from the working unit and mounted on different rail vehicles (work trains, maintenance trains, or even standard freight cars), allowing the same working device to reach various workplaces including those inaccessible by dedicated rail infrastructure.
2Ease of manufacture
If devices are manufactured as custom-made rail-mounted products, then they can be transported to and from the railroad, but transport costs increase and require special permits
Solution Approach 1:
The transport unit is designed with universal mounting capabilities that allow it to be attached to different types of rail vehicles without modification. The detachable connection system enables the device to be transported on standard freight cars or work trains without requiring special permits, as it appears as ordinary cargo rather than modified rail equipment.
3Adaptability or versatility
If the device includes all necessary work equipment, then it can perform various track construction tasks, but the dimensions exceed standard container sizes for cost-effective shipping
Solution Approach 1:
The device incorporates adjustable components that can change position between transport and working modes. During transport, components are reconfigured to minimize the overall dimensions and fit within standard container sizes. During work operations, the same components are adjusted to their functional positions to provide full work capability.
4Ease of manufacture
If the device is designed to be light in weight with a frame structure, then manufacturing cost is reduced, but the device requires more support infrastructure
Solution Approach 1:
The support infrastructure is extracted from the device itself and provided by the external rail vehicle. The device uses a lightweight frame structure without heavy-duty self-contained support systems, relying instead on the rail vehicle's chassis and mounting structure to provide the necessary strength and stability during transport and operation.

AI summary
The device has a working unit e.g. rail lifting arm (7), crane path (8), crane arm (9), lifting and rotation devices (10, 12) and an intermediate bearing (11), for implementing works and forming a transport unit (15) such as a standard container i.e. sea container. The working unit is accommodated in the transport unit. The transport unit is detachably attached on a rail vehicle (1) i.e. railcar. A part of the working unit is adjusted between a transport position and a working position. The transport unit comprises a frame (4), which is detachably attached on the rail vehicle.
