Ballastway TRIZ Cases
- Gantry Crane Work Train for Sequential Track Renewal
A work train uses a pivotable crane jib to remove old track panels and place new ones on graded ballast.
- Railway Track Sensor Mat for Vertical Pressure Distribution
Matrix sensor array on a mat-shaped carrier maps vertical surface pressure distribution to resolve spatial information loss in railway track monitoring.
- Pivotable Sweeping Brush Housing for Track Ballast Maintenance
Rotating the sweeping brush housing about a vertical axis simplifies component replacement and reduces operational downtime during track maintenance.
- Storage Cart Floor Conveyor Belt Adjustment for Bulk Transfer
A storage cart floor conveyor belt adjusts its discharge end position to transfer bulk material.
- Ballast Stripping Machine Same-End Material Handling
A ballast stripper excavates used track material and receives new aggregate through a single end to streamline maintenance workflows.
- Rail-Mounting Assembly with Asymmetric Elastomeric Stiffness
Asymmetric rail-mounting assembly uses angled elastomeric pads to enhance lateral stiffness, preventing anchor bolt failure.
- Eccentric Transmission Device for Infrastructure Component Displacement
A transmission device converts rotary movement into translational displacement using an eccentric ground contact point.
- Railroad Aggregate Dumping System with Real-Time Gate Control
Hydraulic actuators adjust multiple delivery gates in real time, resolving operator safety risks while maintaining precise aggregate placement.
- Saddle-Shaped Polymer Railroad Tie Reducing Center Bounding
A saddle-shaped polymer railroad tie redistributes ballast to maintain track gauge.
- Movable Seat Measuring Instrument for Chain Wear Detection
A measuring instrument with a movable seat and resilient member detects chain length differences through dynamic positioning.
- Low-Pressure Polyurethane Ballast Production Process
A low-pressure process applies polyurethane reaction mixtures between ballast stones to create stable foam structures.
- Thermoplastic Wood Fiber Coating for Weather Protection
A continuous thermoplastic and wood fiber coating protects wooden cores from moisture.
- Dual-End Conveyor Silo Wagons for Bidirectional Material Transfer
Segmented and merged conveyor belts eliminate separate transfer units, resolving directional constraints while maximizing transport volume.
- Segmented Railway Regulator Blade Design
Segmented railway regulator blades with irregular side edges enable single-handed replacement and reduce material waste.
- Threaded Rod Groove Securing Rail Suspension
A threaded rod with a groove engages a pin part to secure the connection.
- Tamping Unit Force-Path Recording for Ballast Quality
A tamping unit records force-path progression during vibration cycles to derive characteristic values for ballast quality assessment.
- Slab Trackway Escape Route Formwork and Sleeper Integration
Removable formwork creates stable slab trackway escape routes without impeding elastic sleeper block mobility or requiring prefabricated panels.
- Railway Track Substructure Repair via On-Site Material Recovery
A railway track repair method recovers mixing zone material for new substructures.
