Rail Reprofiling Device Waste Pickup Segment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current abrasive rail reprofiling methods fail to effectively recover all abrasive waste, particularly the high-energy spark jets, leading to environmental concerns and safety risks for operators, with existing systems only capturing 10-20% of waste due to the high kinetic and thermal energy of heavy particles.
Innovation Solution
A device with a waste pickup segment positioned along the geometric axis of the waste jet, coated with ceramic materials and equipped with cooling and vibrational systems to absorb and reflect energy, ensuring nearly all abrasive waste, including heavy particles, is collected and transported to a container for disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a box under reduced pressure with lateral walls is used to collect waste, then light dust particles are suctioned up and transported, but heavy spark particles cannot be collected due to their high kinetic energy and form accumulations on lateral walls
Solution Approach 1:
The invention extracts the heavy spark particles from the harmful spark jet by positioning a collection segment directly in the path of the particle jet, where particles are removed from the hazardous trajectory and directed into a collection container, thereby eliminating the harmful effect while improving recovery
Solution Approach 2:
A deflecting element is introduced as an intermediary component that redirects the particle jet containing heavy spark particles into the collection segment, mediating between the harmful spark jet and the collection system to enable effective capture of high-energy particles
2Productivity
If high power abrading units are used to remove large quantities of metal quickly, then productivity increases, but the amount of abrasive waste generated increases significantly
Solution Approach 1:
The invention implements a comprehensive waste recovery system that captures both light dust particles via suction and heavy spark particles via the collection segment positioned in the particle jet path, enabling recovery of nearly all abrasive waste material generated during high-productivity rectification operations
3Loss of substance
If the collection segment is positioned in the geometric axis of the particle jet, then heavy spark particles are effectively captured, but thermal energy concentrates on the collection segment
Solution Approach 1:
The invention converts the harmful thermal energy concentrated in the particle jet into a beneficial cooling effect by introducing a fluid circulation system that absorbs excess heat, transforming the thermal hazard into a controllable parameter that enables effective particle capture

AI summary
A device for the continuous reprofiling of the rails of railroads includes at least one abrasive rail reprofiling unit (2) guided along the railroad tracks and comprising at least one abrasive disk (3) that can be pressed against a rail (1). This device notably includes at least one abrasive-waste pickup (20) having at least one segment forming a collection port (21). This segment is placed in the immediate vicinity of at least one abrasive disk (3) and into the geometric axis (41) of the major waste jet (40) produced during operation of this abrasive disk (3). The segment (21) simultaneously cooperates with means for transporting the waste. Moreover, each waste pickup (20) includes elements for reflecting and absorbing the kinetic and thermal energy that allow the formation of agglomerations of matter on the pickup to be avoided.
