At the same time, since the track cleaning component is connected to the rotating wheel 5 in a transmission manner, the rotating wheel 5 drives the track cleaning component to clean the surface of the rotating rail 3, so that the track cleaning component can match the rotation of the rotating rail 3. That is, when the rotating wheel 5 drives the second moving frame 4 to rotate relative to the rotating rail 3, the track cleaning component correspondingly cleans the debris on the rotating rail 3 in front of the rotating wheel 5, thereby preventing impurities or dust from affecting the rotation of the second moving frame 4 relative to the rotating rail 3.

[0045] Example 2

[0046] See also Figure 2-3On the basis of Example 1, the self-cleaning component includes a drive shaft 6, the drive shaft 6 is rotatably connected to the fixed plate 15, and the upper end of the drive shaft 6 is transmission-connected to the rotating wheel 5, and the lower end of the drive shaft 6 is fixedly connected to the second turntable 9, and the second turntable 9 is provided with a transmission gear 10;

[0047] A first rotating disk 7 is disposed at the middle section of the driving shaft 6 , and an abutting sleeve 8 is disposed on the lower surface of the first rotating disk 7 . The side of the abutting sleeve 8 smoothly transitions with the first rotating disk 7 .

[0048] The self-cleaning component includes a first connecting plate 11 disposed on the lower surface of a fixed plate 15 , a deflection shaft 12 is fixedly connected to the first connecting plate 11 , a rotating block 13 is rotatably connected to the deflection shaft 12 , and a scraper 14 is rotatably penetrated in the rotating block 13 .

[0049] One end of the scraper 14 that passes through the rotating block 13 is fixedly connected with a deflection gear 16, and the deflection gear 16 is arranged at the end of the rotating block 13 away from the scraper 14. The center of the surface of the side of the deflection gear 16 away from the scraper 14 is fixedly connected with a linkage ball head 17, and the linkage ball head 17 can abut against the lower surface of the first rotating disk 7 or the abutment sleeve 8;

[0050] When the linkage ball head 17 abuts against the lower surface of the abutment sleeve 8 , the deflection gear 16 can mesh with the transmission tooth 10 .

[0051] A reset rod 18 is fixedly connected to the rotating block 13, one end of the reset rod 18 away from the rotating block 13 is connected to one end of a reset spring 19, the other end of the reset spring 19 is fixedly connected to a reset fixing rod 20, the reset fixing rod 20 is fixedly connected to a second connecting plate 21, and the second connecting plate 21 is fixedly connected to the lower surface of the fixed plate 15.

[0052] The length of the transmission tooth 10 is half the circumference of the deflection gear 16;

[0053] The length of the abutment sleeve 8 corresponds to the length of the transmission tooth 10;

[0054] The width of the scraper 14 is greater than the width of the rotating rail 3 .

[0055] The working principle and beneficial effects of the above scheme:

[0056] When the rotating wheel 5 rotates, since the driving shaft 6 is rotatably connected with the rotating wheel 5, the rotating wheel 5 drives the driving shaft 6 to rotate, and then drives the first rotating disk 7 and the second rotating disk 9 to rotate. When the first rotating disk 7 rotates to the transition section between the first rotating disk 7 and the abutting sleeve 8 and abuts with the linkage ball head 17, in the process of rotating to abutting with the abutting sleeve 8, the linkage ball head 17 is squeezed, driving the rotating block 13 to rotate around the deflection shaft 12, so that the scraper 14 is parallel to the rotating rail 3. At this time, the transmission tooth 10 on the second rotating disk 9 is meshed with the deflection gear 16. The rotation of the second rotating disk 9 drives the deflection gear 16 to rotate, and then drives the scraper 14 to rotate, so that the scraper 14 is turned over, and due to the scraper 14 The width is greater than the width of the rotating rail 3. When the scraper 14 flips over, the debris scraped off the surface of the rotating rail 3 by the scraper 14 is flipped and dumped on both sides of the rotating rail 3, completing the self-cleaning of the scraper 14. After that, the driving shaft 6 drives the first rotating disk 7 to rotate to the transition section between the first rotating disk 7 and the abutment sleeve 8 and abuts against the linkage ball head 17 again. At this time, the transmission gear 10 and the deflection gear 16 are no longer engaged, and the plane of the scraper 14 is in a state parallel to the rotating rail 3. Under the action of the pulling force of the reset spring 19, the scraper 14 rotates around the deflection shaft 12 within the limit of the transition section between the first rotating disk 7 and the abutment sleeve 8 until the scraper 14 abuts against the rotating rail 3, and cleans the rotating rail 3 again.

[0057] The self-cleaning component cleans the track cleaning component, thereby ensuring the cleanliness of the track cleaning component at all times, thereby ensuring the stability of the track cleaning component in cleaning the surface of the rotating rail 3, and preventing impurities or dust from affecting the rotation of the second moving frame 4 relative to the rotating rail 3.

[0063] The first linkage rod 25 is fixedly connected with a first claw 23 and a toggle rod 26 , which are respectively located on the left and right sides of the first linkage rod 25 . The second linkage rod 28 is fixedly connected with a second claw 24 , which is arranged opposite to the first claw 23 .

[0064] The side surface of the toggle rod 26 is fixedly connected to one end of the first elastic member 27, and the other end of the first elastic member 27 is fixedly connected to the inner wall of the housing 22;

[0065] A slide plate 43 is slidably connected in the housing 22, the left end of the slide plate 43 is fixedly connected to one end of the second elastic member 37, the other end of the second elastic member 37 is fixedly connected to the inner wall of the housing 22, and a trigger head 38 is fixedly connected to the slide plate 43, and the trigger head 38 is located between the first claw 23 and the second claw 24;

[0071] The working principle and beneficial effects of the above scheme:

[0072] When the second mobile frame 4 is rotated to be flush with other mobile frames, a stable connection is performed through a stable connection assembly to ensure the stability of multiple transmissions;

[0073] First, the toggle lever 26 is bent to make the toggle lever 26 overcome the resistance of the first elastic member 27 and move. The toggle lever 26 drives the first linkage lever 25 to move, and the second linkage lever 28 is moved in the opposite direction through the linkage piece 30. The interval between the first claw 23 and the second claw 24 increases, and the trigger block 35 is driven by the second linkage lever 28 to move to the side of the card slot 39 and squeeze the card rod 41, so that the card rod 41 overcomes the elastic force of the third elastic member 40 and moves. The second card block 42 is disengaged from the card joint 44, and the slide plate 43 moves, driving the trigger head 38 to extend, and the first card block 36 and the card slot 39 engage the trigger block 35 to prevent the trigger block 35 from moving. When the second mobile frame 4 rotates to be flush with other mobile frames, its The clamping joint 45 connected to the other moving frame abuts between the first clamping claw 23 and the second clamping claw 24 and squeezes the trigger head 38. The trigger head 38 overcomes the elastic force of the second elastic member 37 and moves inward, driving the slide plate 43 to move, thereby releasing the restriction on the trigger block 35, that is, releasing the restriction on the first linkage rod 25 and the second linkage rod 28. The first linkage rod 25 is reset under the action of the first elastic member 27, and the second linkage rod 28 is reset through the linkage plate 30. The interval between the first clamping claw 23 and the second clamping claw 24 connected to the first linkage rod 25 and the second linkage rod 28 is reduced, and the third clamping block 46 and the fourth clamping block 47 are clamped, thereby completing the stable connection between the second moving frame 4 and the other moving frames.
