Solution Overview

Problem

Existing track processing machines are not efficiently adaptable to changing track conditions, such as different types of sleepers, requiring lengthy conversion times and work disruptions.

Innovation Solution

A pivotable sweeping device that can rotate 180° relative to the machine frame, allowing for quick adaptation of sweeping brushes to suit various sleeper types, with height-adjustable and interchangeable brushes for optimal cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the sweeping device uses fixed sweeping brushes for a specific sleeper type, then the cleaning effectiveness for that sleeper type is optimized, but the adaptability to different sleeper types deteriorates

Engineering Contradiction:
Improveadaptability to different sleeper typesVSAvoidconversion time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The sweeping device is made pivotable about a vertical axis, allowing the sweeping brushes to be dynamically repositioned between different working positions. This dynamic configuration enables the same device to adapt to different sleeper types (e.g., wooden sleepers in switch areas vs. concrete sleepers on open track) without requiring physical conversion, thereby resolving the contradiction between adaptability and conversion time.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the sweeping device is equipped with multiple sweeping brushes for different sleeper types, then the versatility increases, but the device complexity increases

Engineering Contradiction:
Improveversatility for different sleeper typesVSAvoidsweeping device configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single sweeping device is designed to perform multiple functions by pivoting to different positions. The same sweeping brushes serve different sleeper types (wooden and concrete) through positional adjustment rather than requiring separate dedicated brushes for each sleeper type. This universal design achieves versatility while avoiding the complexity of multiple independent sweeping devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If the sweeping brushes are fixed in position, then the structural simplicity is maintained, but the productivity when changing track conditions deteriorates

Engineering Contradiction:
Improvecleaning efficiency across different track sectionsVSAvoidsweeping device structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The sweeping device incorporates a pivot mechanism about a vertical axis, allowing rapid reconfiguration between different track sections with different sleeper types. This dynamic positioning capability maintains high productivity across varying track conditions while adding minimal structural complexity compared to fixed configurations.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a machine (1) for processing a track (2), comprising a machine frame (4) supported on rail bogies (3). A sweeping device (6), the height of which can be adjusted by drives (5), is arranged on the machine frame and has two sweeping brushes (12, 13), which are arranged one behind the other in a working direction (10) and which can be rotated about horizontal axes (11) extending perpendicular to the working direction (10). The sweeping device (6) can be pivoted relative to the machine frame (4) about a vertical axis (14). Thus, the sweeping device (6) can be adapted quickly to changing track conditions.
