The volume of railway transportation is large, and the wear and extrusion of rails by trains during long-term operation, as well as the impact during train starting and braking, will inevitably cause fatigue and damage to the rails. Therefore, the railway system requires regular damage inspection of rails when they are first built or put into operation, so as to detect problems in the rails as early as possible and take corresponding measures to ensure the safety of railway operation.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-3 In this embodiment, a dual-track ultrasonic flaw detection robot walking mechanism includes two tracks 1, a body 2 is slidably installed on the top between the two tracks 1, rotating shafts 3 are rotatably installed at the four corners of the body 2, and moving wheels 4 are fixedly installed on the outer surfaces of the four rotating shafts 3, ultrasonic detection wheels 5 are installed on the left and right sides of the body 2, and a cleaning component 6 is fixedly installed on the front side of the body 2.
[0021] It should be noted that when the rails are initially built or in operation, the rails need to be inspected for damage through ultrasonic probe wheels 5 to ensure safe operation. The ultrasonic probe wheel 5 uses the characteristics of ultrasonic energy penetrating deep into metal materials and reflecting at the edge of the interface when entering from one section to another to inspect part defects. When the ultrasonic beam passes from the surface of the part through the probe to the inside of the metal, reflected waves are generated when encountering defects and the bottom of the part, forming pulse waveforms on the fluorescent screen. The defect position and size are judged based on these pulse waveforms. Combined with the traditional single-rail flaw detector, the detection rate of rail damage can be effectively improved.
[0022] The cleaning assembly 6 includes two connecting plates 601, and connecting plates 601 are slidably installed on the opposite sides of the two tracks 1. Movable shafts 602 are rotatably installed inside the two connecting plates 601. Pulleys 603 are fixedly installed on the outer surfaces of the two movable shafts 602 and the front rotating shaft 3. Every two pulleys 603 are connected by belts 604. Slide plates 606 are slidably installed on the inner walls of the two tracks 1, and cleaning rollers 605 are fixedly installed on the outer surfaces of the two movable shafts 602.
[0023] Specifically, when the machine body 2 runs on the surface of the track 1, the rotating shafts 3 on the left and right sides of the machine body 2 will rotate continuously, and the rotation of the two front rotating shafts 3 will drive the movable shaft 602 to rotate through the transmission between the pulley 603 and the belt 604. Therefore, the movable shaft 602 will drive the cleaning roller 605 to rotate, and the mud and stones on the track 1 will be cleaned by the cleaning roller 605, thereby improving the accuracy of the detection data of the ultrasonic probe wheel 5.
[0024] One end of the two movable shafts 602 away from the connecting plate 601 is slidably connected to the surface of the slide plate 606 , the outer surfaces of the two cleaning rollers 605 are in contact with the surface of the track 1 , and the two cleaning rollers 605 are both in contact with the front side of the body 2 .
[0025] Specifically, providing the connecting plate 601 and the sliding plate 606 can improve the stability of the cleaning roller 605 during rotation.
[0026] An adjustment component 7 is fixedly installed on the outer surface of the body 2, and the adjustment component 7 includes two L-shaped plates 701. The L-shaped plates 701 are fixedly installed on the left and right sides of the body 2. Rotating rods 702 are rotatably installed inside the two L-shaped plates 701, and driving gears 703 are fixedly installed on the outer surfaces of the two rotating rods 702. Movable rods 704 are rotatably installed inside the two L-shaped plates 701, and driven gears 705 are fixedly installed on the outer surfaces of the two movable rods 704. Elastic friction blocks 706 are fixedly installed on the opposite sides of the two L-shaped plates 701.
[0027] Specifically, the adjustment function can make the probe on the ultrasonic probe wheel 5 better fit the surface of the track 1 , so that the ultrasonic probe wheel 5 is always in contact with the surface of the track 1 and adapts to the curvature and ups and downs of the track 1 .
[0028] The two driving gears 703 are meshed with the outer surface of the driven gear 705 , and one end of the two rotating rods 702 is fixedly connected to the surface of the ultrasonic probe wheel 5 , and the two ultrasonic probe wheels 5 are in contact with the surface of the track 1 .
[0029] Specifically, the coordination between the driving gear 703 and the driven gear 705 can improve the stability of the ultrasonic probe wheel 5 during adjustment.
[0030] One side of the two elastic friction blocks 706 is in contact with the inner wall of the track 1 .
[0031] Specifically, the elastic friction block 706 on the inner wall of the L-shaped plate 701 is slidably fitted against the outer wall of one end of the track 1, which can ensure that when the body 2 moves at the top of the track 1, the L-shaped plate 701 moves with the track 1, thereby ensuring that the ultrasonic probe wheel 5 is always at the top of the track 1 and avoiding the movement of the ultrasonic probe wheel 5.
[0032] To summarize, the walking mechanism of the dual-track ultrasonic flaw detection robot is equipped with a cleaning component 6. When the body 2 walks on the track 1, the rotating shafts 3 on the left and right sides of the body 2 will rotate continuously, and the rotation of the two front rotating shafts 3 will drive the movable shaft 602 to rotate through the transmission between the pulley 603 and the belt 604. Therefore, the movable shaft 602 will drive the cleaning roller 605 to rotate, and the mud and stones on the track 1 are cleaned by the cleaning roller 605, so that the ultrasonic probe wheel 5 can avoid inaccurate data of the track 1 at the detection point of the ultrasonic probe wheel 5 while moving, thereby ensuring the accuracy of the measurement data.
[0033] Furthermore, by setting up the cooperation between the body 2, the ultrasonic probe wheel 5 and the elastic friction block 706, the ultrasonic probe wheel 5 contacts the surface of the track 1 for detecting the track 1, and the angle change of the ultrasonic probe wheel 5 can be adjusted under the rotation of the rotating rod 702, so that the ultrasonic probe wheel 5 is always in contact with the surface of the track 1 to adapt to the curvature and ups and downs of the track 1. The adjustment function can make the probe on the ultrasonic probe wheel 5 better fit the surface of the track 1, ensure that the ultrasonic wave can be effectively transmitted into the interior of the track 1, and improve the flexibility and accuracy of the detection.
