Technical Field

[0001] The utility model belongs to the technical field of box beam processing, in particular to a box beam anti-corrosion coating device. Background Art

[0002] Steel box girder, also known as steel plate box girder, is a commonly used structural form for large-span bridges. It is called a steel box girder because of its box-like appearance. During the production of steel box girders, in order to ensure that its surface has rust-proof and corrosion-resistant effects, it is usually sprayed with paint, so a coating device is required.

[0003] Although the existing box girder anti-corrosion coating equipment can meet the basic needs of spraying box girders, the spraying width that can be covered is often fixed. Therefore, during the process of spraying the box girder, users need to move and adjust the spraying device in a time-consuming and laborious manner to achieve sufficient coverage of the to-be-sprayed areas of box girders of various widths. In the process of moving and adjusting the spraying device, in order to avoid insufficient spraying affecting the spraying effect, the user's operation requirements are high, which is not only very troublesome, but also affects the overall efficiency of the box girder spraying treatment. Utility Model Content

[0025] like Figure 1 As shown, the mobile guide module includes a transverse cylinder 51 respectively provided at the left and right side ends of the fixed frame 1. A transverse plate 52 is respectively inserted into the two transverse cylinders 51. The free ends of the two transverse plates 52 are respectively provided with a connecting frame 53. Guide wheels 54 are rotatably provided on the two connecting frames 53. The outer ends of the two connecting frames 53 are also provided with connecting bearings 55. The outer rings of the connecting bearings 55 are connected to the connecting frames 53. Adjustment screws 56 are also transversely threadedly provided on the two side ends of the fixed frame 1.

The two adjusting screws 56 are respectively provided with a screw handle 57.

[0026] like Figure 1 As shown, the travel wheel 3 is also provided with a wheel brake 6.

[0027] After the user has placed the device on the outside of the box beam in the width direction and completed the initial position adjustment, the user locks the walking wheel 3 by the wheel brake 6 to stop the movement of the device. Then, the user can use the handle 57 to rotate the two adjusting screws 56 relative to the side ends of the fixing frame 1 to adjust the cross plate 52, the connecting frame 53, and the guide wheel 54 so that the cross plate 52, the connecting frame 53, and the guide wheel 54 move toward the direction close to the box beam, so that the two guide wheels 54 are respectively attached to the outer side walls of the left and right side ends of the box beam. After that, the user can adjust the position of the device conveniently and smoothly by making the two guide wheels 54 fit respectively with the two sides of the box beam.

[0028] Then, the paint spray head 47 can be connected to the paint supply device through the paint guide hose, and then the slide seat of the linear slide 42 can be moved left and right, so that the horizontal position of the paint spray head 47 is adapted to the box beam, and the horizontal position of the paint spray head 47 is adjusted. Then, the output shaft of the telescopic push rod 43 is telescopically adjusted, so that the paint spray head 47 is close to the top of the box beam, and the vertical position of the paint spray head 47 is adjusted, so that the paint spraying range of the paint spray head 47 can cover one side end of the top of the box beam.
