Description

Technical Field

[0001] The present invention relates to the field of track detection technology, and more particularly to an adjusting device for a track flaw detector. Background Art

[0002] Ultrasonic flaw detection is a method of inspecting defects in parts by utilizing the characteristic that ultrasonic energy can penetrate deep into metal materials and reflect at the edge of the interface when entering another section from one section. 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 surface of the part, forming pulse waveforms on the fluorescent screen. The position and size of the defect are judged based on these pulse waveforms. However, during the use of existing ultrasonic flaw detectors, the staff generally manually pushes the device to move on the rails to inspect the rails.

[0036] Working principle of the present invention:

[0037] First, the moving wheel 5 and the driving wheel 77 of the device are placed on the rail. At this time, the distance sensor 97 will measure the distance between the probe wheel 99 and the waist of the track. When the measured distance is not equal to the predetermined distance, it means that the probe wheel has deviated relative to the track. At this time, the distance sensor 97 will control the motor 2 92 to work, so that the motor 2 92 drives the threaded rod 2 93 fixedly connected to its output shaft to rotate. When the threaded rod 2 93 rotates, it drives the threaded seat 94 threadedly connected to it to move, so that the threaded seat 94 drives the mounting frame 96 fixedly connected to it to move. When the mounting frame 96 moves, it drives the probe wheel 99 to move synchronously, so as to readjust the probe wheel 99 to align with the geometric center line of the track cross section.

[0038] The motor 1 78 is controlled to rotate forward, so that the motor 1 78 drives the full gear 1 79 fixedly connected to its output shaft to rotate. When the full gear 1 79 rotates, it drives the ratchet set 2 710 meshing with it to rotate. At this time, the ratchet set 1 69 rotates idly. When the ratchet set 2 710 rotates, it drives the linkage rod 711 fixedly connected to it to rotate, so that the linkage rod 711 drives the driving gear 714 fixedly connected to it to rotate. When the driving gear 714 rotates, it drives the driven gear 713 meshing with it to rotate, so that the driven gear 713 drives the rotating rod 72 fixedly connected to it to rotate. When the rotating rod 72 rotates, it drives the driving wheel 2 73 fixedly connected to it to rotate, so that the driving wheel 2 73 drives the driven wheel 2 75 to rotate through the belt 2 74. When the driven wheel 2 75 rotates, it drives the installation shaft 76 fixedly connected to it to rotate, so that the installation shaft 76 drives the driving wheel 77 fixedly connected to it to rotate, and when the driving wheel 77 rotates, it pushes the device to move;

[0039] When the device moves, it will drive the moving wheel 5 to rotate, so that the moving wheel 5 drives the rotating shaft 4 fixedly connected to it to rotate. When the rotating shaft 4 rotates, it will drive the linkage shaft 814 fixedly connected to it to rotate, so that the linkage shaft 814 drives the driving wheel 3 813 fixedly connected to it to rotate. When the driving wheel 3 813 rotates, it will drive the driven wheel 3 811 to rotate through the belt 3 812, so that the driven wheel 3 811 drives the cross bar 810 fixedly connected to it to rotate.

When the vertical shaft 817 rotates, the residual gear 818 fixedly connected thereto is driven to rotate. At this time, the residual gear 818 will mesh with the gear ring 86, so that the gear ring 86 drives the rotating disk 82 fixedly connected thereto to rotate forwardly. When the residual gear 818 is out of mesh with the gear ring 86, the residual gear 818 will mesh with the full gear 2 87, so that the full gear 2 87 drives the gear ring 86 meshed therewith to rotate. When the driven bevel gear 2 816 rotates, it drives the rotating disk 82 to rotate reversely, thereby driving the vertical rod 83 to rotate back and forth continuously. When the vertical rod 83 rotates, it drives the connecting disk 84 fixedly connected thereto to rotate, so that the connecting disk 84 drives the brush 85 fixedly connected thereto to rotate synchronously. When the brush 85 rotates, it cleans the debris on the rail.

[0040] When the detection wheel 99 detects that the rail is damaged, the detection wheel 99 will transmit the detection signal to the detection box 2, so that the detection box 2 controls the motor 78 to reverse. At this time, the full gear 79 will drive the ratchet group 69 meshing with it to rotate. At this time, the ratchet group 2 710 is idling. When the ratchet group 69 rotates, it will drive the connecting rod 68 fixedly connected to it to rotate, so that the connecting rod 68 drives the driving wheel 610 fixedly connected to it to rotate. When the driving wheel 610 rotates, it will drive the driven wheel 612 to rotate through the belt 611, so that the driven wheel 612 drives the driving shaft 613 fixedly connected to it to rotate. The driving shaft 613 is When it rotates, it will drive the active cone wheel 614 fixedly connected to it to rotate, so that the active cone wheel 614 drives the driven cone wheel 615 meshing with it to rotate, and the driven cone wheel 615 will drive the transmission shaft 616 fixedly connected to it to rotate when it rotates, so that the transmission shaft 616 drives the threaded rod 65 fixedly connected to it to rotate, and when the threaded rod 65 rotates, the threaded sleeve 66 threadedly connected to it will move downward, so that the threaded sleeve 66 drives the push plate 64 fixedly connected to it to move synchronously, and when the push plate 64 moves, it will push the marking material in the inner cavity of the storage box 62 to the side of the damaged part of the rail through the discharge port 63.
