[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-4 This utility model provides an embodiment of a high-speed railway bridge pier maintenance spraying device, including a fixed plate 1 and a positioning bracket 2. The positioning bracket 2 is fixedly connected to the bottom end of the fixed plate 1. A fixed frame 9 is provided at the bottom end of the fixed plate 1. An annular tube 10 is provided inside the fixed frame 9. A nozzle 22 is fixedly connected to the inner wall of the annular tube 10. Water inlets 23 are fixedly connected to both sides of the top end of the annular tube 10. A drive motor 11 is fixedly installed at the top end of the fixed frame 9. The output end of the drive motor 11 passes through the inside of the top end of the fixed frame 9 and is fixedly connected to a right angle gear 12. The annular tube 10 has toothed grooves on its outside, and right-angle gears 12 mesh with the annular tube 10. There are three sets of right-angle gears 12. A drive motor 3 is fixedly installed on both sides of the top of the fixed plate 1. A connecting shaft 4 is fixedly connected to the output end of the drive motor 3. A winding roller 5 is fixedly installed on the outside of the connecting shaft 4. A steel wire rope 6 is wound on the outside of the winding roller 5. A reserved groove 7 is provided inside both sides of the top of the fixed plate 1. The bottom end of the steel wire rope 6 passes through the interior of the reserved groove 7 longitudinally and is fixedly connected to a hook 8. A fixed seat 24 is fixedly connected to both sides of the top of the fixed frame 9. The hook 8 is detachably fastened to the outside of the fixed seat 24. Specifically, such as Figure 1 and Figure 2As shown, when the drive motor 11 is turned on, the right-angle gear 12 is driven to rotate. When the right-angle gear 12 rotates, it can drive the meshing annular tube 10 to rotate inside the fixed frame 9, which makes it easy to adjust in all directions during spraying, making the spraying more uniform and improving the quality of spraying maintenance.
[0017] The top of the fixed plate 1 has an internal movable groove 19. A connecting pipe 18 is longitudinally installed inside the movable groove 19. A water injection pipe 20 is fixedly connected to the top of the connecting pipe 18. A valve 21 is fixedly installed on the outside of the water injection pipe 20. A water storage box 16 is fixedly connected to the bottom of the connecting pipe 18. Flexible hoses 17 are fixedly connected to both sides of the bottom of the water storage box 16. The bottom of the flexible hoses 17 is fixedly connected to the water inlet 23. The connecting pipe 18 is embedded in the movable groove 19 and can rotate. The water storage box 16 and the connecting pipe 18 are both cylindrical; Specifically, such as Figure 1 and Figure 4 As shown, because the connecting pipe 18 can rotate in the movable groove 19, the external water pipe can be connected to the water injection pipe 20. Opening the valve 21 makes it easy to inject clean water into the connecting pipe 18, then into the water storage box 16, and finally into the water inlet 23 through the hose 17, so that it enters the annular pipe 10 and is sprayed to the outside through the nozzle 22, making the hose 17 less likely to fall to the ground and cause external wear.
[0018] A support base 13 is fixedly connected to the top end of the annular tube 10, and a mounting frame 14 is fixedly connected to the top end of the support base 13. An auxiliary roller 15 is movably connected inside the mounting frame 14. Three sets of auxiliary rollers 15 are provided and are evenly distributed. Specifically, such as Figure 1 and Figure 3 As shown, when the drive motor 3 is turned on, the connecting shaft 4 is driven to rotate, which can drive the external winding roller 5 to rotate, thereby driving the bottom fixed frame 9 to move up and down. When the fixed frame 9 moves up and down, the auxiliary roller 15 can roll outside the pier to assist in its stable lifting and lowering, making it more suitable for lifting and lowering.
[0019] Working Principle: In use, this invention first uses a positioning bracket 2, which is fixed to the outside of the reinforcing steel bar at the top of the pier. An external water pipe is connected to the water injection pipe 20 via a snap-fit connector. The water injection pipe 20 has a pre-drilled interface for this connector. The drive motor 3 is turned on, driving the connecting shaft 4 to rotate, which in turn rotates the external winding roller 5, thereby causing the bottom fixed frame 9 to move up and down. When the fixed frame 9 moves up and down, the auxiliary roller 15 can roll outside the pier to assist in stable lifting and lowering, making it more suitable for lifting and lowering. Then, the... Valve 21 facilitates the injection of clean water into the connecting pipe 18, then into the water storage box 16, and finally into the water inlet 23 through the hose 17, allowing it to enter the annular pipe 10 and be sprayed outwards through the nozzle 22. This prevents the hose 17 from falling to the ground and causing external wear. Finally, the drive motor 11 is turned on to drive the right-angle gear 12 to rotate. When the right-angle gear 12 rotates, it can drive the meshing annular pipe 10 to rotate inside the fixed frame 9, thus facilitating all-round adjustment during spraying, making the spraying more uniform, and improving the quality of spray maintenance.
[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
