Description

Technical Field

[0001] The invention relates to the technical field of rail detection devices, in particular to an ultrasonic-based rail detection device. Background Art

[0002] As a key part of rail transit, the integrity and reliability of track play a vital role in the safe operation of rail transit. Track inspection is mostly done manually, and maintenance workers can only rely on manual labor and small equipment. The efficiency, accuracy and reliability of track inspection need to be improved. Therefore, relying solely on manual labor and small handheld equipment is increasingly unable to meet the inspection needs of modern rail transit.

[0003] After searching the Chinese patent with the announcement number CN110758457B, an ultrasonic rail detection device is disclosed, which has a simple structure, convenient maintenance and easy use. The patent can automatically detect the rails. When cracks and gaps appear on the rails, the damaged rail ends can be marked, which makes it convenient for subsequent maintenance personnel to quickly repair them. At the same time, the built-in ultrasonic detection device greatly improves the efficiency and accuracy of track detection and reduces the workload of traditional detection personnel.

[0004] Based on the above search and the prior art, it is found that when inspecting rails, most of the time, ultrasonic waves are emitted from the side, and then reflected or transmitted ultrasonic waves are received. The positions of defects and damages of the rails are calculated according to the changes in the ultrasonic waves. However, the amount of marking paint cannot be selected according to the size and specifications of the defects and damages of the rails. During maintenance, the maintenance plan cannot be determined quickly and accurately, and defects on the top of the rails are difficult to detect, which reduces the inspection efficiency of the rails.

[0035] Working principle: When testing the rails, the testing vehicle 3 is placed on the rails 2. The testing vehicle 3 is connected to the rails 2 through the iron wheel 14 at the bottom. When the iron wheel 14 rotates, the testing vehicle 3 also moves. The ultrasonic transmitter 15 on the mounting plate 10 is horizontally set, and the ultrasonic wave emitted horizontally passes through the rails 2. The ultrasonic transmitter 2 16 is tilted, and the ultrasonic wave emitted obliquely passes through the top of the rails 2. Part of the ultrasonic wave is reflected and received by the ultrasonic receiver 1 17 and the ultrasonic receiver 2 18 on the mounting plate 10. According to the change of the ultrasonic wave, the defects or damage on the rails 2 are detected. The transmitted ultrasonic wave passes through the rails 2 and acts on the resonance plate 1 19 and the resonance plate 25. , there are defects and damages on the rail 2, and when the transmitted ultrasonic wave changes, it will cause the resonance plate 19 and the resonance plate 25 to vibrate. When the rail 2 has defects and damages in the horizontal direction, the ultrasonic wave received by the resonance plate 19 changes, and the resonance plate 19 vibrates, thereby driving the slide plate 22 to slide through the spring 20, and the slide plate 22 presses the resisting ball 23, so that the support plate 36 is lifted up, and the mesh plate 33 rises accordingly, and slides at the position of the mesh hole 45 on the liquid inlet box 32. When the mesh plate 33 is lifted up, the mesh and the mesh hole 45 coincide, and when the resonance plate 19 vibrates, the electrical signal is transmitted to the controller 30 through the compression resistor wire 21 and the wire, and then the controller is started. The high-pressure pump 31 transports the pigment to the top of the liquid inlet box 32. When the mesh plate 1 33 overlaps with the mesh hole 45, the pigment enters the side box 41 through the mesh hole 45, and then is sprayed on the rail 2 from the side through the side pipe 24 and the nozzle 1 42 for marking. Similarly, when a damage defect occurs on the top of the rail 2, the pigment enters the liquid inlet box 32, the slide plate 2 27 slides to press the sphere 29, the support plate 2 38 and the mesh plate 2 40 are pressed and slide into the liquid inlet box 32, so that the mesh of the mesh plate 2 40 and the mesh plate 3 46 overlap, and the pigment is sprayed on the top of the rail 2 through the horizontal pipe 43 and the nozzle 2 44. When the resonance plate 1 19 or the resonance plate 2 25 does not vibrate, the mesh plate 1 33 and the mesh hole 45 are staggered. , or the screen plate 2 40 and the screen plate 3 46 are staggered, so that when the pigment enters the liquid inlet box 32, the pigment will only be output from the defective side of the rail 2, and according to the size and specifications of the defect, the transmitted ultrasonic wave is also different, causing the vibration amplitude of the resonance plate 19 and the resonance plate 25 to be different. The larger the defect, the greater the vibration amplitude of the resonance plate 19 and the resonance plate 25, the longer the sphere 1 23 and the sphere 2 29 are lifted up, the greater the amount of pigment output, and the larger the size of the mark, which is convenient for quickly determining the maintenance plan. The horizontal ultrasonic transmitter 15 detects defects in the middle and bottom of the rail 2, and the inclined ultrasonic transmitter 2 16 detects the top of the rail 2.

[0036] When the resonance plate 19 or the resonance plate 25 vibrates rapidly, the sphere 1 23 or the sphere 2 29 is continuously pressed, so that the mesh 1 33 and the mesh 2 40 are always in a pressed state, and the meshes are always connected to ensure that the pigment can be output normally. When the defect of the rail 2 is small and the vibration amplitude of the resonance plate 19 or the resonance plate 25 is small, the size of the mesh overlap leakage is also reduced accordingly, reducing the output of the pigment. When the resonance plate 19 or the resonance plate 25 stops vibrating, the mesh 1 33 or the mesh 2 40 will also be reset under the action of the spring 34 or the spring 4 39, and the pigment is marked by the transmitted ultrasonic wave, and then according to the reflected ultrasonic wave received by the ultrasonic receiver 1 17 and the ultrasonic receiver 2 18, the combination of the transmitted wave and reflected wave detection can provide a more comprehensive assessment of the internal condition of the rail 2. The transmitted wave detection is very effective for detecting the overall integrity of the rail and identifying larger defects, while the reflected wave detection can provide detailed information about the location and size of the defect.

[0037] The driving motor 4 drives the rotating rod 5 to rotate, and the rotating rod 5 cooperates with the bevel gear 1 12 and the bevel gear 2 13 to rotate, thereby driving the movable rod 8 to rotate, and the iron wheel 14 rotates to drive the detection vehicle body 3 to move to detect the rail 2. At the same time, when the rotating rod 5 rotates, it also drives the stirring rod 11 to rotate, and stirs the pigment inside the pigment storage box 6, so that the pigment is always stirred to maintain a liquid state, to prevent precipitation and solidification blockage, or stratification to cause large color differences in pigments at different positions.

Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
