[0027] The following will refer to 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 of 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.

[0028] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0029] Reference Figure 2 , Figure 3 and Figure 4 The utility model provides an embodiment: a railway wheel and rail crack detection simple device, including a supporting main beam 1, both sides of the supporting main beam 1 are fixedly connected with a fixing seat 10, the front side of the fixing seat 10 is fixedly connected with a fixing frame 12, the interior of the fixing frame 12 is fixedly connected with an acoustic wave detection probe 15, both sides of the bottom end of the fixing seat 10 are rotatably connected with a moving roller 14, the bottom end of the fixing seat 10 is installed with a stable clamping component, the top of the supporting main beam 1 is provided with a traction groove 9, and both sides of the interior of the traction groove 9 are slidably connected with a retractable The top of the slider 2 and the retracting slider 2 are both rotatably connected with an adjusting plate 8, an adjusting assembly is installed on the inner side of the adjusting plate 8, and a stable engaging assembly includes a slide groove 17, a mounting plate 19 is fixedly connected to the middle of the slide groove 17, tension springs 16 are fixedly connected to both sides of the mounting plate 19, and connecting blocks 20 are fixedly connected to the outer sides of the tension springs 16, and the bottom end of the connecting block 20 is fixedly connected with a bonding plate 13, and a bonding roller 18 is rotatably connected to the inner side of the bonding plate 13, and the outer sides of the connecting blocks 20 are respectively slidably connected to the inner sides of the slide grooves 17;

[0030] The device is placed on the top of the rail, and the bottom ends of the fixing seat 10 are respectively aligned with the rails on both sides of the rail, and the rails are stuck in the compartment between the bonding plates 13. The device is forced downward, and the protruding point of the bonding roller 18 contacts the rail. As the upper part exerts downward force, the bonding plate 13 moves outward, and the connecting block 20 moves outward inside the slide groove 17. When the bottom end of the fixing seat 10 contacts the top of the rail, the tension spring 16 generates an inward pulling force on the connecting block 20, and the bonding plate 13 is bonded to both sides of the rail for fixing. As the device moves, the bonding plate 13 contacts the side of the rail and rotates, and the moving roller 14 contacts the top of the rail and rotates, making the movement smoother. At the same time, the acoustic wave detection probe 15 is located at the front end of the device, which can timely observe the crack damage of the rail, reduce the complexity and labor of the staff's operation, make the detection more stable, and make the device more convenient to use.

[0031] Reference Figure 1 and Figure 3 The adjustment assembly includes a traction plate 6, a bidirectional threaded rod 4 is threadedly connected to the middle of the traction plate 6, and a rotating handle 3 is fixedly connected to both sides of the bidirectional threaded rod 4. The top of the adjustment plate 8 is rotatably connected to a support plate 5, and both sides of the support plate 5 are fixedly connected to a moving handle 7. The outside of the traction plate 6 is rotatably connected to the inside of the adjustment plate 8;

[0032] By turning the rotating handle 3, the bidirectional threaded rod 4 can be easily rotated with the assistance of the rotating handle 3. The external threads of the bidirectional threaded rod 4 are opposite to each other, and the threads on both sides thereof are in contact with the threads inside the traction plate 6, so that the traction plate 6 is moved inward at the same time. As the traction plates 6 approach each other, the angle between the adjustment plates 8 becomes smaller, so that the retraction sliders 2 on both sides of the traction groove 9 are moved inward at the same time, thereby lifting the adjustment plate 8 upward. As the adjustment plate 8 gradually becomes vertical, the support plate 5 is lifted upward until it is lifted to a suitable height for the staff. Long-distance detection will not cause excessive pressure on the user's waist, thereby improving the user experience of the device.

[0033] Reference Figure 1 , the top of the fixing seat 10 is fixedly connected with an indicator plate 11;

[0034] The indicator plate 11 provides the workers with an indication direction to avoid the acoustic wave detection probe 15 being positioned in the wrong direction and failing to observe the crack in time.

[0035] Working principle: Place the device on the top of the rail, align the bottom end of the fixing seat 10 with the rails on both sides of the rail, and the rails are stuck in the compartment between the bonding plates 13. Apply force downward to the device, and the protruding point of the bonding roller 18 contacts the rail. With the downward force from the upper part, the bonding plate 13 moves outward, and the connecting block 20 moves outward inside the slide groove 17. When the bottom end of the fixing seat 10 contacts the top of the rail, the tension spring 16 generates an inward pulling force on the connecting block 20, and the bonding plate 13 is attached to both sides of the rail for fixing. The rotating handle 3 is turned at this time, and the bidirectional threaded rod 4 is easily turned with the assistance of the rotating handle 3, so that the traction plates 6 are moved inward at the same time. As the traction plates 6 are approached to each other, the angle between the adjustment plates 8 becomes smaller, so that the retraction sliders 2 on both sides of the traction groove 9 are moved inward at the same time, and the support plate 5 is lifted up until it is raised to a suitable level for the staff. At this time, the device is pushed by the moving handle 7. As the device moves, the acoustic wave detection probe 15 is located at the front end of the device, and the crack damage of the rail can be observed in time.
