[0036] As a technical optimization solution of the present invention, the bottom of the slider 303 is fixedly connected to a lamp board 14, and the bottom of the lamp board 14 is fixedly connected to lamp beads 18, and the number of lamp beads 18 is several.

[0037] In this embodiment, by lighting the lamp bead 18 , the staff can quickly observe the positions of the slider 303 and the multi-way solenoid valve 301 on the ground, thereby achieving the effect of facilitating the determination of the position of the slider 303 .

[0038] As a technical optimization solution of the utility model, a fixed block 8 is fixedly connected to the left side of the rotating plate 1, a top column 7 is fixedly connected to the top of the fixed block 8, a ball 15 is rotatably connected to the top of the top column 7, a fixed plate 9 is fixedly sleeved on the surface of the servo motor 4, and the top of the ball 15 is in contact with the bottom of the fixed plate 9.

[0039] In this embodiment, the top of the ball 15 contacts the top of the fixed plate 9, so that the rotating plate 1 can be supported for rotation, so that the rotation of the rotating plate 1 is more stable, thereby achieving the effect of making the rotation of the rotating plate 1 more stable.

[0040] As a technical optimization solution of the utility model, the front side and the rear side of the top of the servo motor 4 are fixedly connected with a mounting plate 5, and the interior of the mounting plate 5 is provided with mounting holes 6, and the number of the mounting holes 6 is two.

[0041] In this embodiment: workers ride on lifting equipment to bring the mounting plate 5 into contact with the steel that needs to be sprayed with corrosion-resistant paint to enhance the corrosion resistance of the steel frame bridge, and then use external bolts to pass through the mounting holes 6, and use the external bolts to thread the steel of the steel frame bridge. At this time, the servo motor 4 and the turn plate 1 can be fixed to the bottom of the steel frame bridge, thereby achieving the effect of facilitating the connection between the servo motor 4 and the steel of the steel frame bridge.

[0042] Working principle: First, the staff takes the lifting equipment to put the mounting plate 5 in contact with the steel that needs to be sprayed with corrosion-resistant paint to enhance the corrosion resistance of the steel frame bridge, and then uses the external bolts to pass through the mounting holes 6, and uses the external bolts to thread the steel of the steel frame bridge. At this time, the servo motor 4 and the rotating plate 1 can be fixed to the bottom of the steel frame bridge, and then the external paint delivery pipe is connected to the input pipe 2. At this time, the staff can return to the ground, and at this time, the reduction motor 11 is controlled to rotate. The rotation of the reduction motor 11 can drive the rubber wheel 12 to rotate through the output. Since the rubber wheel The surface of 12 contacts with the surface of the rotating plate 1, and the rubber wheel 12 rotates to move the slider 303. The slider 303 slides inside the slide groove 16, which facilitates the movement of the slider 303, thereby moving the multi-way solenoid valve 301. By controlling the multi-way solenoid valve 301, the nozzles 302 at different positions of the multi-way solenoid valve 301 can spray corrosion-resistant paint on the surface of the steel frame bridge steel. When the slider 303 moves, the anti-slip block 13 slides inside the anti-slip groove 17, and the anti-slip block 13 can limit the slider 303 to prevent the slider 303 from slipping out of the slide groove 16. By controlling the servo motor 4 to rotate, the servo motor 4 can drive the rotating plate 1 to rotate through the output shaft. At this time, the top of the ball 15 contacts the top of the fixed plate 9, and the rotating plate 1 can be supported for rotation, so that the rotation of the rotating plate 1 is more stable. Through the rotation of the rotating plate 1 and the movement of the slider 303, and in combination with the nozzles 302 at multiple locations of the multi-way solenoid valve 301, corrosion-resistant paint can be sprayed on steel frame bridge steel in a larger range, and the steel frame bridge steel can be maintained to enhance the corrosion resistance of the steel frame bridge steel. By lighting the lamp beads 18, it is convenient for the staff to The positions of the slider 303 and the multi-way solenoid valve 301 can be quickly observed from the ground. The staff only needs to stay at a height to install the mounting plate 5 and then return to the ground, which greatly reduces the time the staff stays at height, reduces safety hazards, and avoids the problem of spraying corrosion-resistant paint on steel frame bridge steel. Most of the existing methods for enhancing the corrosion resistance of steel frame bridge steel are to manually hang at high altitudes and use a brush roller to paint. There are great safety hazards when manual labor is in high altitudes for a long time, and it consumes more labor, which affects the efficiency of painting corrosion-resistant paint on steel frame bridge steel.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
