Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion spraying technology for steel box girders, and in particular to an anti-corrosion spraying device for manufacturing steel box girders. Background Technology

[0002] As a crucial load-bearing structure in bridge engineering, steel box girders are exposed to complex environments for extended periods, making them susceptible to corrosion, oxidation, and other factors that can lead to decreased structural strength and shortened service life. Therefore, applying anti-corrosion coating to the surface of steel box girders is a key process to ensure their durability and safety. Traditional anti-corrosion spraying techniques rely primarily on manual operation, using solvent-based paints. During application, volatile organic compounds (VOCs) and oil mist are easily generated, posing a threat to the health of construction workers and polluting the surrounding environment.

[0003] However, existing anti-corrosion spraying devices have some shortcomings: First, manual spraying is inefficient and it is difficult to guarantee the uniformity of spraying, especially for the complex curved surface structure of steel box girders, where manual operation is difficult to cover the entire area; Second, the oil mist generated during the spraying process diffuses quickly, and traditional equipment lacks an effective oil mist recovery and treatment mechanism, resulting in a large amount of harmful substances escaping into the air and causing serious environmental pollution. Utility Model Content

An oil storage tank 7 is installed on one side of the outer wall of the paint pump 6. The machine head 3, the spray nozzle 4, and the oil inlet pipe 5 are interconnected. A vision sensor 14 is fixedly connected to the other side of the outer wall of the machine head 3 by screws. A vehicle body 13 is installed on the bottom outer wall of the operating platform 1.

[0024] In this embodiment, the operating platform 1 is moved and positioned via the vehicle body 13. The multi-axis manipulator 2 adopts a multi-axis linkage structure, with a machine head 3 installed at its end. The nozzle 4 at the machine head 3 is connected to the oil storage tank 7 via an oil inlet pipe 5. The paint pump 6 can deliver paint to the nozzle 4. The vision sensor 14 acquires images of the steel box girder surface in real time, generates a three-dimensional spraying path through an algorithm, and controls the multi-axis manipulator 2 to adjust the spraying angle and distance.

[0025] Example 2: A corrosion-resistant spraying device for manufacturing steel box girders. The bottom outer wall of the machine head 3 is provided with an oil suction bucket 8, and an air inlet pipe 9 is fixedly connected to one end of the outer wall of the oil suction bucket 8. A paint filter assembly 10 is provided to one end of the outer wall of the air inlet pipe 9, and an exhaust pipe 11 is connected to the top outer wall of the paint filter assembly 10. The paint filter assembly 10 includes a filter housing 101 fixedly installed on one end of the outer wall of the air inlet pipe 9, a filter element 102 disposed inside the filter housing 101, and an oil collection cylinder 103 screwed to the bottom outer wall of the filter housing 101. The exhaust pipe 11 is fixedly installed on the top outer wall of the filter housing 101, and a blower 12 is installed on one end of the outer wall of the exhaust pipe 11. A connecting plate 15 is welded to the bottom outer wall of the machine head 3, and the oil suction bucket 8 is fixedly connected to the inner wall of the connecting plate 15 by screws.

[0026] In this embodiment, the oil suction hopper 8 is arranged adjacent to the nozzle 4, and its negative pressure is generated by the blower 12. The oil mist can be guided into the filter housing 101 through the air inlet pipe 9. The filter element 102 is made of multi-layer composite material, which can intercept particles.

The connecting plate 15 fixes the oil suction hopper 8 to the bottom of the machine head 3 to prevent vibration from causing displacement.

[0029] Working principle:

[0030] The anti-corrosion paint in the oil storage tank 7 is delivered to the paint pump 6 through the oil outlet 16 and the pipe joint 19. After being pressurized, the paint is delivered to the nozzle 4 of the machine head 3 through the oil inlet pipe 5. The surface features of the steel box girder are identified by the vision sensor 14, and a three-dimensional path signal is generated to drive the multi-axis manipulator 2 to move the nozzle 4 along the preset trajectory to achieve precise spraying. The oil mist generated by spraying is captured by the oil suction bucket 8 and enters the paint filter assembly 10 through the air inlet pipe 9. The filter element 102 separates solid particles and liquid paint. The latter is collected in the oil collection cylinder 103, and the purified gas is discharged by the blower 12 through the exhaust pipe 11.
