Lontron is a company that designs and manufactures equipment for rail vehicle and locomotive maintenance, including underfloor wheel lathes, wheelset ultrasonic flaw detectors, and measurement and monitoring tools for wheelset parameters. These tools are used to restore the wheel profiles of rail vehicles.
All industrial ultrasonic testing applications use flaw detection as their most popular method. High-frequency sound waves typically reflect off of imperfections and produce distinct echo patterns.
These echo patterns are captured and displayed by portable equipment. In many service industries and manufacturing processes, especially those involving the usage of welds and structural metals, ultrasonic testing is a common and safe technique. The paper overviews ultrasonic fault detection theory, practice, and application.
The driver stops the Rail Flaw Detection Vehicle when a potential problem is found and manually checks the area to see if a flaw exists. The size of the fault is then determined, followed by the position inside the rail section. To take corrective action, the operator will give the railroad this information.
Lontron has the world's best Rail Flaw Detection Vehicle and Weld Flaw Detector; we have listed below the best of Lontron's rail flaw detection vehicles:-
To detect internal rail defects at a detection speed of 80 km/h, the GGTS high-speed phased array rail flaw detection vehicle uses fast phased array ultrasonic technology, a pulley carrier trolley, and deep learning technology. It also performs intelligent alarming, automatic positioning, feature parameter extraction, and automatic reporting for over-limit defects. It is appropriate for rail-type detection at 43kg/m, 50kg/m, 60kg/m, 75kg/m, and other weights.
The GWTS phased array rail weld flaw detector combines conventional and phased array ultrasonic technology. It uses a hand-push + semi-automatic scanning method to achieve complete coverage detection of the weld area, carry out an automatic alarm for exceeding the allowable number of flaws, and provide a comprehensive display with an A/B/C/S scan.
The exterior surface of the axle, wheel disc, hubs, etc., is magnetized for inspection using the wheelset fluorescent magnetic particle inspection system. Most of this apparatus comprises the rack, spray mechanism, feeding and discharging device, rotating supporting wheel device, double-row comb-tooth electrode device, UV lamp, LED cold light source, etc. It is appropriate for railway wheelset magnetic particle inspection.
The demagnetization uses half-wave bell attenuation technology, the remanence is steady and reliable, and a double-row comb-shaped vertical lift opens and shuts the coil with high sensitivity, uniform magnetization, and no dead zone.
Automatic alarming; adoption of an energy-efficient and ecologically friendly LED cold light source with low power consumption and long service life.
An SJ pantograph and roof state dynamic inspection system is installed on the depot's vehicle entrance line. It uses high-speed, high-resolution, 3D inspection, and non-contact image processing measurement technology to achieve active automatic detection of vital characteristic parameters and visualization observation of the state of foreign objects and critical components on the vehicle roof. The system is commonly used in metros, high-speed trains, locomotives, and rolling stock for passengers and freight.
The LY wheelset failure dynamic detection system, installed on the depot's entrance line, uses high-precision displacement measurement technology, an ultrasonic flaw detection array, and structured light projection image technology to automatically detect wheel pair dimensions, tread wear, and internal wheel defects in real time. It is appropriate for various types of vehicles, including metros, high-speed trains, locomotives, and rolling stock for passengers and freight.
The LVT Wheel Tread Defect Monitoring System is built to automatically collect wheel tread photographs using high-speed, high-resolution image analysis and measuring technology, current cameras, and AI. The device uses artificial intelligence (AI) technology to identify tread surface flaws like flatness, spalling, and peeling-off automatically. It is appropriate for various types of vehicles, including metros, high-speed trains, locomotives, and rolling stock for passengers and freight.
High-speed trains, locomotives, and rolling stock hollow axles are inspected using the LHZ Hollow Axle Ultrasonic Testing System. The LHZ system uses a round-trip spiral inspection mode and a sophisticated non-contact oil immersion ultrasonic inspection technique to study bulk and outside surface fatigue faults in the hollow axle. It can be used to inspect any hollow axle. It is appropriate for various types of vehicles, including locomotives and EMUs.
The LU In-Service Wheel Ultrasonic Testing System is deployed on the inspection line of high-speed trains, locomotives, rolling stock, and metros light maintenance depots. As wheelsets are placed on the train, flaws in the wheel flange, wheel rim, and wheel disc are automatically and effectively inspected based on the combined use of a phased array, traditional ultrasonic inspection technology, and robotic technology.
The Trackside Brake Pad Condition Monitor System, situated at the entrance line where trains pass, automatically takes pictures of the bottoms of vehicles with brakes on them. The braking area is detected, and the thickness is precisely assessed using AI-drive technology. Brake conditions, such as the loss of a brake pad, can also be seen in addition to wear measurements. The residual life mileage of each particular brake pad can be forecast using the data mining software of this module. It can be used for any type of vehicle, including metros, high-speed trains, locomotives, and rolling equipment for passengers and freight.
