[0002] Road and bridges are structural facilities used to span obstacles (such as rivers, canyons, railways, etc.) so that vehicles can pass smoothly above or below these obstacles. They play a key role in connecting different regions and improving traffic mobility in the road system. In road and bridge construction, dotting devices are used to accurately locate the positions of bridge bearings, measure the verticality and horizontality of bridge components, ensure the correct placement of steel bars and formwork components, help workers identify and correct construction errors, reduce potential structural safety hazards, and provide accurate data support for subsequent inspections and maintenance.

[0003] After retrieval, Chinese Patent Publication No.: CN215561984U discloses a dotting device for road and bridge construction, including a bottom plate.

[0033] Refer to Figure 1 , Figure 4 And Figure 5, the stirring assembly includes a rotating column 17. The rotating column 17 is a cylinder. When the device works, the rotating column 17 rotates following the roller 2. A gear 18 is fixedly connected to the outer wall of the rotating column 17. A bevel gear 19 is meshed with the outer wall of the gear 18. The gear 18 is meshed with the bevel gear 19 to ensure that the gear 18 can drive the bevel gear 19 to maintain the rotation trajectory. A transmission rod 20 is fixedly connected to the front end of the bevel gear 19. The outer wall of the transmission rod 20 penetrates and is rotatably connected to a connecting block 25.

A long rod 23 is fixedly connected to the top of the second connecting gear 22. A scraper 24 is fixedly connected to the upper outer wall of the long rod 23. When the scraper 24 works, it will scrape the pigment on the upper inner wall of the pigment box 3 to prevent the pigment from remaining on the barrel wall and coagulating. A stirring rod 26 is fixedly connected to the lower outer wall of the long rod 23. When the stirring rod 26 works, it will stir the pigment in the pigment box 3 to prevent the pigment from coagulating. The rotating column 17 is fixedly connected to the side wall of the roller 2. The connecting block 25 is fixedly connected to the bottom end of the base 1. The long rod 23 penetrates and is rotatably connected to the inner wall of the pigment box 3. A notch corresponding to the long rod 23 is provided on the pigment box 3 to ensure that the long rod 23 can rotate. The long rod 23 penetrates and is rotatably connected to the inner wall of the base 1. A notch corresponding to the long rod 23 is provided on the base 1 to ensure that the long rod 23 can rotate during work. The side wall of the scraper 24 is in contact with the inner wall of the pigment box 3.

[0034] Referring to Figures 1-3 , the adjusting mechanism includes a pull rod 16. The pull rod 16 is a cylinder. In the initial state, the lower end is inserted into the notch of the guide post 13. The inner side wall of the pull rod 16 is elastically connected to the moving frame 10 through a movable spring 15. The pull rod 16 is slidably connected to the inner wall of the moving frame 10. A notch corresponding to the pull rod 16 is provided on the moving frame 10 to ensure that the pull rod 16 can move vertically on the moving frame 10. A plurality of groups of slots are provided at the top of the guide post 13. The pull rod 16 is inserted into the slots of the guide post 13. A plurality of groups of notches corresponding to the pull rod 16 are provided on the guide post 13 to ensure that the pull rod 16 can be inserted into the notches of the guide post 13 to limit the moving frame 10. The inner side wall of the pull rod 16 is fixedly connected to one end of the movable spring 15. The other end of the movable spring 15 is fixedly connected to the top of the moving frame 10. When the pull rod 16 moves upward, the movable spring 15 is stretched. When resetting, the elastic force of the movable spring 15 is used to drive the pull rod 16 to enter the notch of the guide post 13 for resetting.

[0035] Working principle: When it is necessary to perform single-point marking simultaneously, the external device's electric control delivery box 5 allows the pigment in the pigment box 3 to enter the fixed marker 7 through the existing technology to mark the required points. When it is necessary to perform multi-point marking simultaneously, first, the hand pulls the pull rod 16 upward. The pull rod 16 moves upward and stretches the movable spring 15. When the pull rod 16 leaves the notch of the guide post 13, the hand pulls the pull rod 16 to the left. The pull rod 16 drives the moving plate 12 to move leftward along the outer wall of the guide post 13. The moving plate 12 drives the hinge plate 11, the movable marker 8, and the moving frame 10 to move leftward, expanding the distance between the fixed marker 7 and the movable marker 8. Multiple groups of movable markers 8 move leftward simultaneously with the moving frame 10. At the same time, the hose 6 is stretched as the movable marker 8 moves. When the distance between the movable marker 8 and the fixed marker 7 is adjusted, the movable marker 8 coincides with the notch on the guide post 13. The hand releases the pull rod 16, and using the elastic force of the movable spring 15, the pull rod 16 is brought into the notch of the guide post 13 to complete the limit of the movable marker 8. At this time, the spacing between the movable markers 8 is the same. Push the marking device forward. According to the required number of markings, the external device's electric control delivery box 5 extracts the pigment in the pigment box 3 into the fixed marker 7 and the movable marker 8 through the existing technology to complete the marking. If it is necessary to perform the marking operation again, just repeat the above steps.

[0036] If it is necessary to stir the pigment, when the device is moving, the roller 2 on the marking device will drive the rotating column 17 to rotate. The rotating column 17 will drive the gear 18 to rotate synchronously. The gear 18 will drive the bevel gear 19. The bevel gear 19 will drive the transmission rod 20 and the connecting gear one 21 to maintain the same movement trajectory. The connecting gear one 21 will drive the connecting gear two 22. The connecting gear two 22 will drive the long rod 23, the stirring rod 26, and the scraper 24 to rotate synchronously. The scraper 24 will rotate to clean and scrape the liquid on the pigment box 3. The stirring rod 26 will stir the pigment in the pigment box 3 to prevent the pigment from coagulating. When the roller 2 stops rotating, all components return to the initial state. If it is necessary to stir the pigment again, just repeat the above steps.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
