[0002] Highway bridge engineering refers to all work such as the planning, design, construction, maintenance, and repair of structures that cross water areas, valleys, and all traffic channels. During the maintenance process, it is necessary to spray and maintain the surface of highway bridges to prevent the surface of highway bridges from cracking due to water shortage, thereby affecting the entire highway bridge. There is a spraying maintenance device for highway bridge construction with the publication number of CN 221721385 U, which drives a lead screw to rotate through a driving motor, thereby driving a lifting block to rise, and then driving a disc between the tops of two connecting rods to rise, so that a semi-circular nozzle rises. At the same time, a storage tank is driven to rise, thereby driving two sliders to slide on the chutes on both sides of the inner wall of the hollow box. Then, a water pump is driven to transport the water inside the water tank to the inside of the semi-circular nozzle through a connecting pipe, a water inlet pipe, and a water outlet pipe in sequence, and then spray it out from the inside of the semi-circular nozzle to achieve the effect of simultaneously spraying and maintaining both sides of the highway bridge. However, the spraying area of the above device is fixed and it is inconvenient to adjust according to different maintenance areas, which brings inconvenience to use. Content of the Utility Model

[0025] As Figures 1-5 shown, a spraying and curing device for highway bridge construction includes a support mechanism, and a spraying mechanism for adjusting the spraying and curing area and water volume is arranged on the support mechanism;

[0026] In this embodiment: The support mechanism includes a box body 11. Moving wheels 12 are arranged at the four corners of the lower end of the box body 11. A handrail 13 is fixed at the rear end of the box body 11. A water injection cover 14 is installed at the upper end of the box body 11, which is convenient for moving and supporting the whole.

[0027] In this embodiment: The spraying mechanism includes a support frame 21 fixed on the support mechanism. A rotating shaft 22 is vertically arranged on the support frame 21. A gear 23 is arranged above the rotating shaft 22. A second arc-shaped rack 25 is arranged in front of the gear 23. A first arc-shaped rack 24 is arranged behind the gear 23. Spraying pipes 26 are installed on both the first arc-shaped rack 24 and the second arc-shaped rack 25. Spraying heads 27 are evenly distributed on the front side of the spraying pipes 26. A water pump 28 is arranged behind the support frame 21, which is used to pump out the water liquid in the box body 11 and send it into the spraying pipes 26. The water suction pipe of the water pump 28 is inserted into the box body 11. A sliding groove 201 is formed on the support frame 21. The first arc-shaped rack 24 and the second arc-shaped rack 25 slide on the sliding groove 201. The horizontal height of the first arc-shaped rack 24 is above the horizontal height of the second arc-shaped rack 25. Tooth teeth are arranged on the outer ring of the first arc-shaped rack 24. Tooth teeth are arranged on the inner ring of the second arc-shaped rack 25. The gear 23 meshes with the tooth teeth on the first arc-shaped rack 24 and the second arc-shaped rack 25. Limit plates 211 are arranged at both ends of the first arc-shaped rack 24 and the second arc-shaped rack 25 to limit the moving positions of the first arc-shaped rack 24 and the second arc-shaped rack 25.

[0028] The rotating shaft 22 is rotationally connected to the box body 11 and the support frame 21. A hose is connected between the water inlet end of the spraying pipe 26 and the water outlet end of the water pump 28. A rotating assembly for rotating the rotating shaft 22 is arranged inside the support frame 21. The rotating assembly includes a worm gear 29 fixed on the rotating shaft 22. A worm 210 is meshed on one side of the worm gear 29. A hand wheel is arranged at the front end of the worm 210 after passing through the support frame 21. The worm 210 is rotationally connected to the support frame 21. By rotating the worm 210, it meshes with the worm gear 29 to drive the rotating shaft 22 to rotate, and then the gear 23 meshes and rotates synchronously with the first arc-shaped rack 24 and the second arc-shaped rack 25, so as to overlap or separate the spraying areas of the spraying pipes 26 on the first arc-shaped rack 24 and the second arc-shaped rack 25.

[0029] The working principle and usage process of the utility model: When it is necessary to maintain a highway bridge, according to the width requirement of the maintenance area, rotate the worm 210. The worm 210 meshes and rotates with the worm gear 29 to drive the rotating shaft 22 to rotate. When the gear 23 on the rotating shaft 22 rotates, it meshes with the first arc-shaped rack 24 and the second arc-shaped rack 25, so that the first arc-shaped rack 24 and the second arc-shaped rack 25 move relatively in the sliding groove 201 of the support frame 21, and the spraying area between the first arc-shaped rack 24 and the second arc-shaped rack 25 becomes larger or smaller. Then, push the whole to move, and the water pump 28 pumps the water liquid in the box body 11 into the spraying pipes 26 and sprays it out through the spraying heads 27.

[0030] The basic principles, main features, and advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
