[0002] Rail is the main component of railway tracks. The rail bears the huge pressure of the wheels and transmits it to the sleepers. The rail provides a continuous, smooth and least resistant rolling surface for the wheels. The subway rails bear the huge pressure of vehicles for a long time, which affects the driving safety and comfort.

[0031] The utility model discloses a subway vehicle integrated with a rail flaw detection system, realizing the integrated design of the subway vehicle and the flaw detection system, having a more compact layout and a higher integration degree, occupying as little as possible the passenger compartment space and the flaw detection bogie space, and reducing the cost.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figures 1 to 4 , for the subway vehicle of the integrated rail flaw detection system of the present utility model, which includes a subway car body 1, in-vehicle flaw detection equipment and out-of-vehicle flaw detection equipment. The in-vehicle flaw detection equipment is arranged inside the subway car body 1, and the out-of-vehicle flaw detection equipment is arranged outside the subway car body 1. The in-vehicle flaw detection equipment includes a control system and a coupling water tank. The out-of-vehicle flaw detection equipment includes a flaw detection bogie 2 and an ultrasonic probe wheel 15. The ultrasonic probe wheel 15 is installed on the flaw detection bogie 2 in a lifting manner. The bottom of the flaw detection bogie 2 is connected with a rotatably arranged wheel 18. The wheel 18 is a wheel of the subway vehicle. A laser alignment device 14 is installed on the flaw detection bogie 2, and a laser sensor cleaning device 16 is installed at the bottom of the subway car body 1. The air outlet of the laser sensor cleaning device 16 is arranged corresponding to the laser alignment device 14. The ultrasonic probe wheel 15, the laser alignment device 14, and the laser sensor cleaning device 16 are all communicatively connected to the control system.

[0034] Among them, the laser alignment device 14 ensures good followability between the ultrasonic detection wheel 15 and the rail, guaranteeing the detection effect. The laser sensor cleaning device 16 is installed on the underframe of the subway car body 1 beside the detection bogie 2, and is used to clean the surface dust of the laser alignment device 14. The installation positions are adjacent to each other, which can shorten the length of the air duct and ensure the cleaning effect. The ultrasonic detection wheel 15 uses ultrasonic waves to detect the rail. The ultrasonic flaw detection uses ultrasonic transducers with different frequencies installed in the ultrasonic detection wheel 15 at a certain angle to perform ultrasonic scanning on different parts and angles of the rail.

[0035] For the subway vehicle with the integrated rail flaw detection system of the present utility model, the ultrasonic detection wheel 15, the laser alignment device 14, and the laser sensor cleaning device 16 are arranged at the outer bottom of the subway car body 1, and the control system and the coupling water tank are arranged inside the subway car body 1. Thus, the rail flaw detection system previously installed on special vehicles is installed in ordinary subway vehicles, realizing the integrated design of the subway vehicle and the flaw detection system, having a more compact layout and higher integration degree, without the need to purchase special flaw detection vehicles separately, and reducing the cost.

[0036] Specifically, a detection wheel support frame 13 is connected to the detection bogie 2. The detection wheel support frame 13 is arranged between two adjacent wheels 18. The ultrasonic detection wheel 15 is connected to the detection wheel support frame 13 through a lifting power device, and the detection wheel support frame 13 is connected to the detection bogie 2 through a connecting piece. The lifting power device is a cylinder, and the connecting piece is a connecting bolt. The detection wheel support frame 13 provides a bearing platform for the ultrasonic detection wheel 15. A detection wheel temperature control system, a coupling water system 17, the lifting power device, and the laser alignment device 14 are installed on the detection wheel support frame 13. The coupling water system 17 is communicated with the coupling water tank through a pipeline. The coupling water system 17 transports the coupling water in the coupling water tank between the ultrasonic detection wheel 15 and the rail, acting as an ultrasonic conduction medium. At the same time, the coupling water system 17 provides rim water for the rim of the wheel 18 to lubricate the rim of the wheel 18, reducing the wear and vibration of the wheel 18. The detection wheel temperature control system, the coupling water system 17, and the laser alignment device 14 are all common devices in the existing flaw detection systems and will not be elaborated here.

[0037] In an embodiment, the coupling water system 17 includes a plurality of coupling water spray nozzles. The coupling water spray nozzles spray coupling water onto the rails on both sides of each ultrasonic detection wheel 15. The coupling water can fill the air gap between the detection wheel and the rail. At the same time, the fluidity of the liquid can fill the pits on the rail surface, reducing the probe loss. The coupling water is used as the ultrasonic transmission medium between the ultrasonic detection wheel 15 and the rail, and the under-vehicle rail detection signal is transmitted to the control system. The coupling water spray nozzles corresponding to the wheels 18 spray water onto the rim where the wheels 18 contact the rail to lubricate the rims of the wheels 18.

[0038] Among them, the laser alignment device 14 includes a laser displacement sensor and an electric cylinder. The laser displacement sensor is connected to the probe support frame 13 through a sensor bracket. One end of the electric cylinder is connected to the probe support frame 13, and the other end is connected to the ultrasonic probe 15. The electric cylinder adjusts the height of the ultrasonic probe 15. The laser alignment device 14 scans the rail profile through a two-line laser sensor, calculates the rail position, and then, with the help of the adjustment motor on the probe support frame 13, makes the ultrasonic probe 15 always face the rail surface directly. When the ultrasonic probe 15 is working, it is pushed down by the electric cylinder, and after the operation is completed, the electric cylinder drives the ultrasonic probe 15 to lift. When a system failure occurs, it has an emergency lift function.

[0039] Further, the coupling water system includes a plurality of coupling water spray nozzles. At least one coupling water spray nozzle is arranged on both sides of each ultrasonic probe 15 for spraying water on both sides and the surface of the rail.

[0040] To facilitate the control of the flaw detection system, the control system includes a system cabinet 5, a power supply cabinet 6, a water pump cabinet 10, a probe temperature control cabinet 9, a PLC control cabinet 11, an operation console 12, and an isolation transformer 4. The system cabinet 5, the power supply cabinet 6, and the isolation transformer 4 are arranged on one side of the passage at the end of the subway car body 1 and are surrounded by an interior enclosure 3; the probe temperature control cabinet 9 and the water pump cabinet 10 are arranged on the other side of the passage at the end of the subway car body 1 and are surrounded by another interior enclosure 3. Among them, the system cabinet 5, the power supply cabinet 6, the water pump cabinet 10, the probe temperature control cabinet 9, the PLC control cabinet 11, the operation console 12, and the isolation transformer 4 are arranged at the same end of the subway car body 1. The PLC control cabinet 11 and the operation console 12 are arranged inside the subway car body 1 and are located outside the interior enclosure 3. The PLC control cabinet 11 and the operation console 12 are respectively arranged on both sides of the passage of the subway car body 1. The interior enclosure 3 is connected to the side plate of the passenger compartment, so that the corresponding equipment is arranged in two enclosed spaces, hiding the equipment. There is a passage left between the two different interior enclosures 3, which is not only beautiful but also improves safety.

[0041] In a specific embodiment, the power supply cabinet 6, the isolation transformer 4, and the system cabinet 5 are arranged in sequence, as Figure 2As shown in the figure, the power supply cabinet 6 is arranged close to the end of the subway car body 1. The water pump cabinet 10 and the probe temperature control cabinet 9 are arranged in sequence, and the water pump cabinet 10 is arranged close to the end of the subway car body 1. The PLC control cabinet 11 and the water pump cabinet 10 are arranged on the same side, and the operation console 12 and the system cabinet 5 are arranged on the same side. The power supply for the flaw detection system of the vehicle is AC380V. To isolate the power consumption of the flaw detection system from that of the vehicle to avoid mutual influence, the vehicle power first enters the isolation transformer 4, and then the isolation transformer 4 supplies power to the flaw detection system, ensuring the electrical isolation between the flaw detection system and the vehicle, with no interference between the two, and guaranteeing the stability of the operation of the vehicle and the flaw detection system. The main unit of each system such as the ultrasonic flaw detection system, the cabinet centering system, and the visual liquid monitoring system is installed in the system cabinet 5, specifically including the ultrasonic system chassis, the ultrasonic power supply chassis, the control and display computer, the playback computer, the automatic centering control chassis, the automatic centering power supply chassis, the signal synchronization unit, and the network switch. The power supply cabinet 6 is installed with the visual liquid monitoring unit chassis, the lighting unit chassis, the cabinet power distribution unit chassis, the inclination control chassis, the UPS host, and the battery pack. The UPS uninterruptible power supply can ensure that when the vehicle has an accidental power cut, the interface of the flaw detection system maintains operation to leave time for exporting data, and at the same time plays the role of purifying the power supply. The probe temperature control cabinet 9 is used to control the temperature of the coupling liquid inside the probe at a constant temperature during detection to ensure the detection effect. The water pump cabinet 10 is the central control of the water circuit. It can draw coupling water from the coupling water tank and spray it on the surface of the rail, and also has the functions of blowing air through the pipeline, heating the coupling water, and adding antifreeze in a low-temperature environment. The PLC control cabinet 11 is installed outside the equipment room. It is mainly responsible for controlling the lifting of the probe and the on-off of the coupling water, and has a small volume. The operation console 12 is the place for operators to operate, and there is a display screen on it, which can meet the needs of two people to work simultaneously. Among them, the specific structure settings and connections of the system cabinet 5, the power supply cabinet 6, the water pump cabinet 10, the probe temperature control cabinet 9, the PLC control cabinet 11, the operation console 12, and the isolation transformer 4 are the common structures in the flaw detection system in the prior art, and will not be elaborated here.

[0042] Further, the coupling water tank includes a main coupling water tank 7 and a secondary coupling water tank 8, so as to increase the water capacity. The main coupling water tank 7 and the water pump cabinet 10 are arranged on the same side and are located within the interior enclosure 3 where the water pump cabinet 10 is located. The secondary coupling water tank 8 and the system cabinet 5 are arranged on the same side and are located within the interior enclosure 3 where the system cabinet 5 is located.

The main coupling water tank 7 is arranged on the side of the probe temperature control cabinet 9 away from the water pump cabinet 10, and the secondary coupling water tank 8 is arranged between the power supply cabinet 6 and the isolation transformer 4.

[0043] To facilitate the filling of coupling water, both the main coupling water tank 7 and the auxiliary coupling water tank 8 are provided with water inlets. The main coupling water tank 7 and the auxiliary coupling water tank 8 are also provided with overflow outlets and communication ports. The communication pipe is connected to the communication ports of the main coupling water tank 7 and the auxiliary coupling water tank 8, facilitating the connection between the main coupling water tank 7 and the auxiliary coupling water tank 8 and enabling the auxiliary coupling water tank 8 to supplement the main coupling water tank 7. The main coupling water tank 7 is provided with a water outlet, which is communicated with the water pump cabinet 10. The communication pipe is arranged at the outer bottom of the subway car body 1. The main coupling water tank 7 and the auxiliary coupling water tank 8 supply water to the water pump cabinet 10.

[0044] To improve the stability of the car body, the main coupling water tank 7 and the auxiliary coupling water tank 8 have the same capacity and are symmetrically arranged about the central position of the flaw detection bogie 2. The main coupling water tank 7 and the auxiliary coupling water tank 8 are connected by an undercarriage communication pipe, which is beneficial to vehicle weight distribution and the water pipeline design is relatively simple.

[0045] To facilitate improving the position stability of the flaw detection system, the isolation transformer 4, the system cabinet 5, the power supply cabinet 6, the main coupling water tank 7, the auxiliary coupling water tank 8, the probe temperature control cabinet 9, the water pump cabinet 10, the PLC control cabinet 11, and the operation console 12 are all connected to the C-groove on the car body floor through bolt fasteners. The system cabinet 5 and the power supply cabinet 6 are relatively tall and also have fixed points with the C-groove on the side wall of the car body to prevent the cabinets from shaking. The main coupling water tank 7 and the auxiliary coupling water tank 8 also have fixed points with the C-groove on the side wall of the car body. To achieve a beautiful structure, balance the weight, and save space, the isolation transformer 4, the system cabinet 5, the power supply cabinet 6, and the auxiliary coupling water tank 8 are installed in the interior decoration enclosure 3 on the first side of the vehicle to form an equipment room. The main coupling water tank 7, the probe temperature control cabinet 9, and the water pump cabinet 10 are installed in the interior decoration enclosure 3 on the other side.

[0046] To facilitate the operation of the staff, the operation console 12 and the PLC control cabinet 11 are installed in the open space inside the carriage of the subway car body 1. There are wire and cable connections between the equipment rooms on the vehicle to realize the control of the flaw detection system. There are wire connections between the equipment on the vehicle and the equipment under the vehicle to realize the control function.

The ultrasonic probes 15 are installed on both sides of the probe support frame 13 and are lifted pneumatically, with a power-off automatic lifting function.

[0047] The subway vehicle of the integrated rail flaw detection system of the utility model includes a subway car body 1, a flaw detection bogie 2, an interior enclosure 3, an isolation transformer 4, a system cabinet 5, a power supply cabinet 6, a main coupling water tank 7, a secondary coupling water tank 8, a wheel probe temperature control cabinet 9, a water pump cabinet 10, a PLC control cabinet 11, an operation console 12, a wheel probe support frame 13, a laser alignment device 14, an ultrasonic wheel probe 15, and a coupling water system 17.

On the basis of ensuring convenience and aesthetics, it reduces the occupation of the passenger compartment space. The wheel probe support frame 13 is installed below the flaw detection bogie 2, does not occupy the space of the car body underframe, and at the same time ensures better track following performance.

[0048] The flaw detection working process of the subway vehicle of the integrated rail flaw detection system of the utility model:

[0049] Close the main power circuit breaker in the power supply cabinet 6, close the main air switch of the distribution unit, and turn on the UPS power supply to supply power and start up the ultrasonic subsystem, the automatic alignment subsystem, and the auxiliary system smoothly.

[0050] Start the ultrasonic control software: The staff operates on the operation console 12 to start the flaw detection software, the ultrasonic A-scan display software, the double liquid level display software, and the alignment operation software.

[0051] Control the alignment with the manual rocker placed on the tabletop of the operation console 12: Before the automatic alignment detection starts, it is necessary to manually adjust the alignment first. Monitor the state of the wheel probe under the vehicle through the visual liquid monitoring unit, and manually adjust the alignment of the wheel probe with the manual rocker. After adjustment, turn on the automatic alignment, and at this time the manual rocker is shielded.

[0052] The working mode is adjusted to automatic, and the system is started for detection. During the detection, the ultrasonic detection wheel 15 slowly descends under the control of the PLC control cabinet 11, and the ultrasonic detection wheel 15 closely adheres to the rail. There are coupling water spray nozzles on both sides of each ultrasonic detection wheel 15. The water pump cabinet 10 pumps water from the coupling water tank to the coupling water spray nozzles, which are sprayed onto the rails on both sides of each ultrasonic detection wheel 15. The coupling water can fill the air gap between the ultrasonic detection wheel 15 and the rail, and at the same time, the fluidity of the liquid can fill the surface pits to reduce the probe loss. During the flaw detection process, the laser sensor of the automatic centering system has been scanning the rail, and the electric cylinder adjusts in real time, so that the ultrasonic detection wheel 15 can adjust its position in real time and always remain on the rail. The laser sensor cleaning device 16 includes a laser sensor air box, and the laser sensor air box blows air on the laser sensor of the laser centering device 14 to keep the surface of the laser sensor free from the influence of water and dust, ensuring the stability and accuracy of the laser centering device 14. During the flaw detection process, the coupling water system 17 takes water from the coupling water tank through the water pump cabinet 10 and sprays rim water on the four wheels 18 of the flaw detection bogie 2. The coupling liquid inside the ultrasonic detection wheel 15 is controlled at a constant temperature during detection by the probe temperature control cabinet 9. The detection results are combined with the mileage data of the synchronous positioning system, and the alignment of the measurement data and the mileage data can be achieved. After the flaw detection is completed, the ultrasonic detection wheel 15 is retracted to end the flaw detection work.

[0053] After the measurement is completed, use the flaw detection playback software to realize the retrieval of the detection data, the playback and display of the detection data, the automatic identification of defects, the classification of defects, the generation of detection reports and flaw detection logs.

[0054] After the data copy is completed, shut down and power off the system.
