[0026] A first card frame 5 is fixed to the top surface of the front frame 2, and a second card frame 6 is fixed to the top surface of the rear frame 3. The first card frame 5 and the second card frame 6 are arranged opposite to each other, and a slide rail 7 is arranged between the first card frame 5 and the second card frame 6. The first card frame 5 and the second card frame 6 are correspondingly buckled on both sides of the slide rail 7 by adjusting components. Rollers are arranged on the inner top surfaces of the first card frame 5 and the second card frame 6. The first card frame 5 and the second card frame 6 cooperate to form a slide. The box moves on the slide rail 7 by the rollers of the slide. The moving box drives the optical device 1 to move synchronously, and the optical device 1 performs data acquisition and processing on the train wheel pairs on the track. The adjustment components make the first card frame 5 and the second card frame 6 cooperate and be connected to the two sides of the slide rail 7. At this time, the rollers on the inner top surfaces of the first card frame 5 and the second card frame 6 are correspondingly located on the top surfaces on both sides of the slide rail 7, and the slide slides on the slide rail 7 through the rollers. The moving slide drives the optical device 1 inside the box to move synchronously.

A rotating frame 11 is provided at the front end of the square rod 8, and the front end of the square rod 8 is movably inserted into the rear side of the rotating frame 11, and the front side of the rotating frame 11 passes through the first bracket 5. A gear 12 is fixed to the rear end of the rotating rod 10 and the front end of the rotating frame 11, and the rear side of the gear 12 on the front side is in contact with the front side of the first bracket 5, and the front side of the gear 12 on the rear side is in contact with the rear side of the second bracket 6. Racks 13 are provided on the front side of the first bracket 5 and the rear side of the second bracket 6, and two adjacent gears 12 are matched by the rack 13 for transmission. When the gear 12 is rotated, the rotating gear 12 uses the rack 13 to drive the adjacent gear 12 to rotate synchronously. The rotating gear 12 uses the rotating frame 11 to drive the circular plate 9 at the rear end of the square rod 8 to rotate. At this time, the circular plate 9 uses the rotating rod 10 to drive the gear 12 on the rear side to rotate, thereby ensuring that the two square rods 8 rotate synchronously.

[0028] The surface of the square rod 8 is sleeved with an elastic member 14, one end of the elastic member 14 is connected to the front side of the circular plate 9, and the other end of the elastic member 14 is connected to the rear side of the rotating frame 11. Two circular frames 15 are fixed to the front side of the second bracket 6, and the two circular frames 15 correspond to the two square rods 8 one by one. The circular frames 15 are spirally sleeved on the surface of the circular plate 9 at the rear end of the square rod 8. The rotating square rod 8 drives the circular plate 9 to rotate inside the circular frame 15, and the square rod 8 drives the rotating frame 11 to rotate synchronously. A plurality of side frames 16 are fixed to the front end surface of the square rod 8, and the inner wall of the rotating frame 11 is provided with inner grooves corresponding to the side frames 16. When the circular plate 9 rotates inside the circular frame 15, since the circular frame 15 is spirally sleeved on the outer side of the circumference of the circular plate 9, the spiral cooperation between the rotating circular plate 9 and the circular frame 15 makes the circular plate 9 approach the second bracket 6, and the rotating circular plate 9 pulls the side frame 16 of the square rod 8 to move inside the inner groove inside the rotating frame 11, and the square rod 8 gradually moves out from the inside of the rotating frame 11, and the moving circular plate 9 cooperates to pull the elastic member 14, and the rotating circular plate 9 uses the rotating rod 10 to make the gear 12 on the rear side away from the second bracket 6, until the first bracket 5 and the second bracket 6 are cooperated and connected on both sides of the slide rail 7, and the elastic force of the elastic member 14 is used to avoid the extrusion force process between the slide and the slide rail 7, avoid excessive friction loss between the slide and the slide rail 7, and facilitate the slide to slide on the slide rail 7 using the roller.

[0029] When the rotating circular plate 9 approaches the first card rack 5, the circular plate 9 uses the rotating rod 10 to pull the gear 12 on the rear side to approach the second card rack 6, until the front side of the rear side gear 12 is in contact with the rear side of the second card rack 6, the gear 12 is stopped, and when the first card rack 5 and the second card rack 6 are pulled apart, the first card rack 5 slides on the surface of the square rod 8 by means of the rotating frame 11, and the circular plate 9 and the rotating frame 11 cooperate to pull the elastic member 14, so as to adjust the distance between the first card rack 5 and the second card rack 6, and then the relative distance between the front frame 2 and the rear frame 3 can be adjusted, so as to facilitate the inspection and replacement of the optical device 1 inside the box.

[0030] exist Figure 4 and Figure 5 In the embodiment, ring sleeves 17 are fixed on both sides of the interior of the front frame 2, and inner rods 18 are fixed on both sides of the interior of the rear frame 3. The two ring sleeves 17 correspond to the two inner rods 18 one by one, and the ring sleeves 17 are correspondingly sleeved on the surface of the inner rods 18. An inner frame 19 is provided on the inner side of the front frame 2, and the inner frame 19 is installed at the center of the rear side surface of the front frame 2. The optical device 1 is correspondingly placed on the inner side of the inner frame 19. After the front frame 2 and the rear frame 3 are correspondingly snapped together using the adjustment component, the ring sleeve 17 of the front frame 2 is correspondingly sleeved on the surface of the inner rod 18 of the rear frame 3. The snap fit between the ring sleeve 17 and the inner rod 18 prevents the front frame 2 and the rear frame 3 from being misaligned. The rubber ring 4 is used to seal the gap between the front frame 2 and the rear frame 3, so as to conveniently protect the optical device 1 inside the box.

[0031] exist Figure 4 and Figure 6 In the embodiment, a clamping component for limiting the optical device 1 is installed on the inner frame 19, and the clamping component includes two opposite side plates 20, the inner side of the side plates 20 corresponds to the side of the optical device 1, and the rear side of the side plates 20 corresponds to the front side of the rear frame 3. The first card frame 5 and the second card frame 6 separated from each other respectively separate the front frame 2 and the rear frame 3, and a push plate 21 for pushing the optical device 1 to move is arranged on the top of the rear side of the side plate 20. The optical device 1 is placed inside the inner frame 19, and the two side plates 20 cooperate to clamp the optical device 1. When the front frame 2 and the rear frame 3 are close to each other, the rear frame 3 pushes the optical device 1 forward by using the push plate 21, and the optical device 1 moved forward is close to the rear side of the front frame 2, which is convenient for ensuring the stability of the optical device 1 inside the box body, and at the same time, the output end of the optical device 1 is directly attached to the rear side of the front frame 2. During the data collection process, the output end of the optical device 1 avoids the optical device 1 and the front frame 2 from having a severe impact due to external collision, and can protect the optical device 1.

[0032] exist Figure 4 , Figure 6 and Figure 7 In the embodiment, a slide plate 22 is provided on the outer side of the side plate 20, and a rotating plate 23 is provided between the side plate 20 and the slide plate 22. One end of the rotating plate 23 is hinged to the rear end face of the side plate 20, and the other end of the rotating plate 23 is hinged to the rear side face of the slide plate 22. Rings 24 are fixed to the top and bottom of the outer side faces of the slide plate 22. The two side faces of the inner frame 19 correspond to the two slide plates 22 one by one. Slide bars 25 are embedded in the top and bottom of the side faces of the inner frame 19. The ring 24 is sleeved on the surface of the slide bar 25. The surface of the slide bar 25 is sleeved with a first spring 26. One end of the first spring 26 is connected to the front side face of the ring 24, and the other end of the first spring 26 is connected to the rear side face of the front frame 2. The top and bottom of the slide plate 22 are both plugged with plug rods 27, the outer side surface of the side plate 20 is provided with a slide groove corresponding to the inner end of the plug rod 27, the inner end of the plug rod 27 is fixed with an inner plate 28, the plug rod 27 slides inside the slide groove using the inner plate 28, and a second spring 29 is sleeved on the surface of the plug rod 27, one end of the second spring 29 is connected to the outer side surface of the side plate 20, and the other end of the second spring 29 is connected to the inner side surface of the slide plate 22. When the front frame 2 and the rear frame 3 approach each other, the elastic force of the first spring 26 is greater than the elastic force of the second spring 29. When the front side of the rear frame 3 contacts the push plate 21, the push plate 21 drives the side plate 20 to move forward while driving the rotating plate 23. The rotating rotating plate 23 makes the side plate 20 move away from the slide plate 22. The moving side plate 20 slides on the surface of the inner plate 28 at the inner end of the insertion rod 27 using the sliding groove. At this time, the two opposite side plates 20 approach each other. In the process of approaching the optical device 1, the side plate 20 pulls the insertion rod 27 to move. The insertion rod 27 gradually approaches the optical device 1, and the side plate 20 cooperates with the slide plate 22 to pull the second spring 29 in the process of moving, until the two opposite side plates 20 cooperate to clamp the optical device 1, thereby completing the preliminary limitation of the optical device 1.

[0033] When the rear frame 3 uses the push plate 21 to push the optical device 1 forward, the two side plates 20 cooperate to clamp the optical device 1. At this time, the side plates 20 cooperate with the slide plate 22 to limit the rotating plate 23 to prevent the rotating plate 23 from rotating. The moving side plate 20 uses the rotating plate 23 to drive the ring 24 of the slide plate 22 to slide on the surface of the slide rod 25. The ring 24 squeezes the first spring 26 during the sliding process. The elastic force of the first spring 26 is used to prevent the optical device 1 from directly impacting the front frame 2. The elastic force of the first spring 26 and the second spring 29 cooperate. At this time, the clamping component can stably clamp the optical device 1 to ensure the stability of the optical device 1 inside the box.

[0034] Working principle of the present invention:

[0035] Reference Figures 1 to 7 As shown, the optical device 1 is placed on the inner side of the inner frame 19. When the gear 12 is rotated, the rotating gear 12 uses the rack 13 to drive the adjacent gear 12 to rotate synchronously. The rotating gear 12 uses the rotating frame 11 to drive the circular plate 9 at the rear end of the square rod 8 to rotate. At this time, the circular plate 9 uses the rotating rod 10 to drive the gear 12 at the rear side to rotate, thereby ensuring that the two square rods 8 rotate synchronously.

[0036] When the circular plate 9 rotates inside the circular frame 15, since the circular frame 15 is spirally sleeved on the outer side of the circumference of the circular plate 9, the spiral cooperation between the rotating circular plate 9 and the circular frame 15 makes the circular plate 9 approach the second bracket 6, and the rotating circular plate 9 pulls the side frame 16 of the square rod 8 to move inside the inner groove inside the rotating frame 11, and the square rod 8 gradually moves out from the inside of the rotating frame 11, and the moving circular plate 9 cooperates to pull the elastic member 14, and the rotating circular plate 9 uses the rotating rod 10 to make the gear 12 on the rear side away from the second bracket 6, until the first bracket 5 and the second bracket 6 are cooperated and connected on both sides of the slide rail 7, and the elastic force of the elastic member 14 is used to avoid the extrusion force process between the slide and the slide rail 7, avoid excessive friction loss between the slide and the slide rail 7, and facilitate the slide to slide on the slide rail 7 using the roller.

[0037] When the front frame 2 and the rear frame 3 approach each other, the elastic force of the first spring 26 is greater than the elastic force of the second spring 29. When the front side of the rear frame 3 contacts the push plate 21, the push plate 21 drives the side plate 20 to move forward while driving the rotating plate 23. The rotating rotating plate 23 makes the side plate 20 move away from the slide plate 22. The moving side plate 20 slides on the surface of the inner plate 28 at the inner end of the insertion rod 27 using the sliding groove. At this time, the two opposite side plates 20 approach each other. In the process of approaching the optical device 1, the side plate 20 pulls the insertion rod 27 to move. The insertion rod 27 gradually approaches the optical device 1, and the side plate 20 cooperates with the slide plate 22 to pull the second spring 29 in the process of moving, until the two opposite side plates 20 cooperate to clamp the optical device 1, thereby completing the preliminary limitation of the optical device 1.

[0038] When the rear frame 3 uses the push plate 21 to push the optical device 1 forward, the two side plates 20 cooperate to clamp the optical device 1. At this time, the side plates 20 cooperate with the slide plate 22 to limit the rotating plate 23 to prevent the rotating plate 23 from rotating. The moving side plate 20 uses the rotating plate 23 to drive the ring 24 of the slide plate 22 to slide on the surface of the slide rod 25. The ring 24 squeezes the first spring 26 during the sliding process. The elastic force of the first spring 26 is used to prevent the optical device 1 from directly impacting the front frame 2. The elastic force of the first spring 26 and the second spring 29 cooperate. At this time, the clamping component can stably clamp the optical device 1 to ensure the stability of the optical device 1 inside the box.

[0039] After the front frame 2 and the rear frame 3 are correspondingly snap-fitted by using the adjustment components, the ring sleeve 17 of the front frame 2 is correspondingly sleeved on the surface of the inner rod 18 of the rear frame 3. The snap fit between the ring sleeve 17 and the inner rod 18 prevents the front frame 2 and the rear frame 3 from being misaligned. The rubber ring 4 is used to seal the gap between the front frame 2 and the rear frame 3, so as to protect the optical device 1 inside the box body.

[0040] The slide slides on the slide rail 7 via rollers, and the moving slide drives the optical device 1 inside the box to move synchronously. The moving optical device 1 collects image information data of the train wheelset through the transparent front frame 2. The moving optical device 1 can comprehensively collect the front and rear sides of the train wheelset to ensure the comprehensiveness of data collection.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
