[0002] Track rollers are mechanical rollers that provide high-strength support and are often used inside metal tracks. Track rollers require assembly and welding during production, and after welding, their internal structure must be inspected using a flaw detector to ensure production quality. However, existing flaw detection machines still have certain usage defects during use. The existing X-ray flaw detector weighs about 30 kg. Due to its heavy weight, it is difficult for workers to move the equipment over long distances directly by manpower. Other props such as carts must be used for assistance. When using it outside, carrying auxiliary props affects the portability of the equipment, which is very inconvenient. Patent authorization announcement number CN219302316U discloses a portable X-ray flaw detector. The patent comprises a support rod, a first outer ring groove, a bottom plate, and a universal wheel, in conjunction with a sleeve, a fixed groove, and a clamping groove. The support rod can be pulled back and slid on the inner side of the inner ring to dock and secure with the fixed groove or the clamping groove, respectively. When the support rod is secured to the fixed groove, it is in a retracted state, which does not affect the normal use of the flaw detector. When the support rod is secured to the clamping groove, it is in an extended state, with the universal wheel located outside the flaw detector and capable of supporting and sliding the wheel, thereby reducing the difficulty and manpower required to move the flaw detector. Patent authorization publication number CN217033818U discloses an adjustable position flaw detector. The design is used to adjust the height of the flaw detector through the drive motor, turntable, slide bar, slider, and pin shaft. The utility model uses the motor, rotating shaft, ball screw, transmission block, and ball nut pair to adjust the lateral position of the flaw detector.

[0019] Example 1: This example Figure 1-Figure 5 As shown, in order to solve the problem that the existing flaw detection machine is difficult to automatically feed, the process of automatic feeding of the flaw detection machine is disclosed, and the effect of automatic feeding of the flaw detection machine is achieved. The specific content is as follows: A base plate 1 and a working box 2 fixedly mounted on the upper end of the base plate 1; A support frame 3 is fixedly mounted on the upper end of the work box 2, and a telescopic rod 4 is fixedly mounted inside the support frame 3, and a sliding plate 8 is fixedly mounted on the lower end of the telescopic rod 4. At the same time, a flaw detection mechanism 5 is provided on the lower end of the sliding plate 8. A blanking plate 6 is fixedly mounted on the upper end of the work box 2, and a supporting foot 7 is fixedly mounted on the lower end of the bottom plate 1; A drive motor 9 is fixedly installed inside the working box 2, and a reciprocating screw 10 is fixedly installed at the output end of the drive motor 9, and the reciprocating screw 10 is rotatably connected to the working box 2; The interior of the working box 2 is provided with a feeding structure for automatically conveying supporting rollers; The feeding structure includes a moving block 11, and the moving block 11 is threadedly mounted on the outside of the reciprocating screw 10, and a support plate 12 is fixedly mounted on the upper end of the moving block 11, and the support plate 12 is slidably connected to the working box 2; A placement frame 13 is rotatably mounted on the upper end of the support plate 12, and a support member 14 is slidably mounted inside the placement frame 13. A rubber pad 15 is fixedly mounted on the upper end of the support member 14. At the same time, the upper end of the support member 14 has an inwardly concave curved surface structure. Two sets of steel ropes 41 are fixedly mounted on the upper end of the support plate 12, and the ends of the steel ropes 41 away from the support plate 12 are fixedly connected to the upper end of the sliding plate 8. A lifting gear plate 16 and a moving gear plate 17 are slidably installed inside the support plate 12, and the lifting gear plate 16 and the moving gear plate 17 are vertically distributed when viewed from the front, and a rotating gear cylinder 18 is rotatably installed inside the support plate 12, and the rotating gear cylinder 18 is respectively engaged with the lifting gear plate 16 and the moving gear plate 17, and the upper end surface of the lifting gear plate 16 is tightly fitted with the lower end surface of the placement frame 13.

[0020] The fixing tube 19 is located inside the mounting tube 20 , and the fixing tube 19 and the mounting tube 20 are slidably connected. An air outlet 21 is opened inside the mounting tube 20 .

[0021] When using the flaw detection machine for the track roller processing, first place the flaw detection machine at the position where it needs to work. After the flaw detection machine is placed at the required position, the track roller can be inspected by the flaw detection machine. When the support frame 13 is moved to the lower end, the driving motor 9 is rotated to drive the reciprocating screw 10 to rotate forward, and the rotation of the reciprocating screw 10 can make the moving block 11 move. The movement of the moving block 11 will drive the placing frame 13 and the supporting member 14 to move through the supporting plate 12. At this time, the supporting member 14 will drive the supporting wheel at its upper end to move. At this time, the supporting wheel will move toward the inside of the supporting frame 3, and in the process of the placing frame 13 moving, the distance between the placing frame 13 and the sliding plate 8 will be reduced, and the wire rope 41 will pull the sliding plate 8 downward. At this time, the telescopic rod 14 will expand and make the sliding plate 8 slide downward inside the supporting frame 3. At this time, the flaw detection mechanism 5 will follow the sliding plate 8 to move downward and approach the supporting wheel. After the support member 14 moves to the lower end of the support frame 3, the flaw detection mechanism 5 can perform flaw detection on the supporting wheel. During the detection, the driving motor 9 stops working; After the inspection is completed, it is possible to directly determine whether there are defects in the internal structure of the supporting wheel. At this time, the drive motor 9 can continue to rotate forward, and then the moving block 11 and the support plate 12 can continue to move to the right. In the process of the support plate 12 moving downward, the right side of the moving tooth plate 17 will contact the working box 2 and be squeezed by the working box 2. At this time, the moving tooth plate 17 will stop moving, and the support plate 12 will continue to move and make the rotating gear cylinder 18 rotate under the action of the moving tooth plate 17, and the rotating When the gear cylinder 18 rotates, it will drive the lifting gear plate 16 engaged with it to move, and the lifting gear plate 16 will move upward and push the placement frame 13 to rotate on the upper end of the support plate 12. At this time, the placement frame 13 will drive the support member 14 to move synchronously and cause the support member 14 to deflect. The rotation of the support member 14 will cause the supporting wheel at its upper end to roll to the upper end of the blanking plate 6 and fall from the upper end of the blanking plate 6, thereby completing the use process of the flaw detection machine and effectively improving the efficiency of the use of the flaw detection machine.

[0022] Example 2: This example Figure 1-Figure 5 As shown, in order to solve the problem of the flaw detection machine avoiding the stable transportation of the supporting wheels, the process of the flaw detection machine for stable transportation is disclosed, and the effect is achieved. The specific content is as follows: The upper end of the working box 2 is provided with a shock absorbing structure to protect the supporting wheels; The shock-absorbing structure includes a fixing tube 19 and a mounting tube 20 , wherein the fixing tube 19 is fixedly mounted on the outer side of the lower end of the support member 14 , and the mounting tube 20 is fixedly mounted on the inner side of the lower end of the placement frame 13 ; The shock absorption structure further includes a fixed rod 22, and the fixed rod 22 is fixedly installed inside the placement frame 13, and a moving rod 23 is slidably installed outside the fixed rod 22; A rotating rod 25 is rotatably mounted inside the moving rod 23, and the upper end of the rotating rod 25 is rotatably connected to the support member 14. A supporting spring 24 is sleeved on the outer side of the fixed rod 22, and the supporting spring 24 is located between the moving rod 23 and the placement frame 13. The lifting structure includes a rotating drum 26 and a connecting rod 27, and the rotating drum 26 is fixedly installed on the end of the reciprocating screw 10 away from the drive motor 9, and the connecting rod 27 is rotatably installed inside the working box 2, and at the same time, the end of the connecting rod 27 away from the working box 2 is rotatably connected to the rotating drum 26.

[0023] When using the flaw detection machine for roller processing, the roller needs to be placed on the upper end of the rubber pad 15. During this process, the support member 14 will be squeezed by the roller and move downward. The downward movement of the support member 14 will drive the fixing cylinder 19 to move downward. The downward movement of the fixing cylinder 19 will squeeze the gas inside the installation cylinder 20 and cause the gas inside the installation cylinder 20 to be discharged through the air outlet 21. In this process, the downward movement speed of the fixing cylinder 19 will be slowed down, thereby slowing down the downward movement of the support member 14 and reducing the collision force between the rubber pad 15 on the upper end of the support member 14 and the roller. And during the downward movement of the support member 14, the support member 14 will push the rotating rod 25 to rotate, and the rotation of the rotating rod 25 will drive the movement rod 23 to move, and the movement of the movement rod 23 will squeeze the support spring 24 and cause the support spring 24 to contract. The contraction of the support spring 24 will slow down the movement of the movement rod 23, thereby slowing down the downward movement speed of the support member 14 again, and can slow down the rebound effect between the supporting wheel and the rubber pad 15 again.

[0024] Example 3: This example Figure 1-Figure 2 and Figure 6-Figure 8 As shown, in order to solve the problem that the existing flaw detection machine needs to be manually moved, the working process of the existing flaw detection machine lifting structure is disclosed, which makes the flaw detection machine easy to move. The specific content is as follows: The interior of the base plate 1 is provided with a lifting structure for controlling the movement and support of the supporting legs 7; A ratchet 28 is fixedly mounted on the outside of the connecting rod 27, and the ratchet 28 is located inside the rotating drum 26. A fixed shaft 29 is fixedly mounted inside the rotating drum 26. A ratchet 30 is rotatably mounted on the outside of the fixed shaft 29, and a torsion spring 31 is nested inside the ratchet 30, and the torsion spring 31 is located outside the fixed shaft 29. The lifting structure also includes a pulley structure 32 and a driven rod 33, and the driven rod 33 is rotatably mounted on the upper end of the base plate 1, and the pulley structure 32 is provided on the outside of the driven rod 33 and the connecting rod 27, and two sets of bevel gears 34 are fixedly mounted on the outside of the driven rod 33; Two sets of rotating screws 35 are rotatably installed inside the bottom plate 1, and the upper ends of the rotating screws 35 are fixedly installed with bevel gears 36, and the bevel gears 36 are meshed and connected with the bevel gears 1 34; A lifting cylinder 37 is installed on the outer thread of the rotating screw 35, and a lifting plate 38 is fixedly installed on the lower end of the lifting cylinder 37, and the lifting plate 38 and the lifting cylinder 37 are slidingly connected to the base plate 1. At the same time, a roller 39 is fixedly installed on the lower end of the lifting plate 38, and a telescopic rod 40 is fixedly installed on the upper end of the lifting plate 38, and the upper end of the telescopic rod 40 is fixedly connected to the base plate 1.

[0025] Before the flaw detection machine is put into operation, the roller 39 needs to be in contact with the ground. During this process, the driving motor 9 needs to drive the reciprocating screw 10 to rotate in the opposite direction. The reverse rotation of the reciprocating screw 10 will drive the rotating drum 26 to rotate synchronously. The rotation of the rotating drum 26 will drive the ratchet 30 to rotate, and the ratchet 30 will engage with the ratchet wheel 28 during the rotation. At this time, the torsion spring 31 will be in an expanded state. At this time, the ratchet wheel 28 will rotate with the rotating drum 26 and drive the connecting rod 27 to rotate. The rotation of the connecting rod 27 will drive the driven rod 33 to rotate through the pulley structure 32. At this time, the bevel gear 1 34 on the outside of the driven rod 33 will rotate along with the driven rod 33, and the bevel gear 1 34 will drive the bevel gear 2 36 meshing with it to rotate, and the rotation of the bevel gear 2 36 will drive the rotating screw 35 to rotate and make the lifting cylinder 37 on the outside of the rotating screw 35 move. At this time, the lifting cylinder 37 will move downward and drive the lifting plate 38 to move downward synchronously, and then the roller 39 can follow the lifting plate 38 to move downward, and the telescopic rod 2 40 at the upper end of the lifting plate 38 will expand, and then the roller 39 can contact the ground, and after the roller 39 moves downward, the supporting foot 7 will be separated from the ground, and the roller 39 can roll and the flaw detector can move, thereby improving the convenience of the flaw detector to move and increasing the overall practicality.
