Description

Technical Field

[0001] The utility model relates to the technical field of bridge painting, in particular to automatic bridge painting equipment. Background Art

[0002] The automatic bridge painting equipment is a high-tech equipment that integrates modern robotics, automation control and painting technologies. It is designed for the automatic painting of bridge steel structures and can significantly improve the painting efficiency and quality. This equipment plays a key role in bridge spraying operations. However, it should be noted that the single-seat design painting equipment may shake when handling large bridges, especially when spraying complex shapes and irregular surfaces. This shaking not only affects the uniformity and accuracy of the spraying, but may also cause paint waste and environmental pollution. In addition, the stability of the lifting platform during the lifting process is equally important. In order to adapt to bridges of different heights, the lifting platform needs to be lifted and lowered frequently. If the stability between the spraying equipment and the side frame cannot be guaranteed during the lifting process, the painting equipment may shake, thereby compromising the spraying quality.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 6 As shown, the automatic bridge painting equipment mainly includes key parts such as a mounting frame 9, a liquid storage tank 10, an infusion device 11, an infusion pipeline 12, a connecting frame 13, a spray nozzle 14 and a front frame 15. The liquid storage tank 10 and the infusion device 11 are firmly mounted on the mounting frame 9, and their function is to store and transport paint. The front frame 15 is connected to the front end of the mounting frame 9, providing a stable mounting platform for the spray nozzle 14. The spray nozzle 14 is mounted on the front frame 15 through the connecting frame 13, and its function is to spray the paint evenly on the surface of the bridge. The spray nozzle 14, the liquid storage tank 10 and the infusion device 11 are connected through the infusion pipeline 12 to form a complete paint delivery system.

[0025] Side frames 7 are installed on both sides of the lower end of the mounting frame 9, and a hydraulic cylinder 8 is provided on the outer side of each side frame 7. The telescopic end of the hydraulic cylinder 8 is connected to the connecting seat 6. By controlling the telescopic movement of the hydraulic cylinder 8, the gap distance between the connecting seat 6 and the side frame 7 can be adjusted. This design enables the equipment to adapt to bridges of different widths and maintain a stable coating effect.

[0026] An intermediate limit frame 16 is provided between the two side frames 7 and is mounted on the connecting seat 6. The function of the intermediate limit frame 16 is to limit the movement range of the side frame 7 to ensure the accuracy and uniformity of the coating. A stabilizing wheel 17 is installed in the inner cavity of each side frame 7, and the two stabilizing wheels 17 are connected by a stabilizing rod 18. The stabilizing rod 18 is inserted into the opening of the side wall of the intermediate limit frame 16. Through the coordinated action of the stabilizing wheel 17, the stabilizing rod 18 and the intermediate limit frame 16, the stability of the side frame 7 during the movement can be maintained.

[0027] A lifting device 5 is installed at the rear end of the connecting seat 6, which is responsible for controlling the height of the entire coating equipment. A base 1 is installed at the lower end of the lifting device 5, and the upper end of the base 1 supports the support frame 2. A top seat 3 is provided at the upper end of the support frame 2, and they together constitute the main structure of the coating equipment. The outer ends of the base 1 and the top seat 3 are connected with moving wheels 4, and the positions of the base 1 and the top seat 3 can be easily adjusted by the moving wheels 4 to meet different coating requirements.

[0028] The base 1, support frame 2 and top seat 3 are fixed together by bolts to form a stable whole. Their cross-section is designed in the shape of an "I", which ensures strength and reduces weight. The moving wheels 4 are fixed to the four corners of the outer ends of the base 1 and the top seat 3 by fasteners, so that the equipment can be stably moved and positioned between the bridge and the ground.

[0029] The two side frames 7 and the middle limit frame 16 are designed to be parallel, which can ensure the linearity and uniformity of the coating. The middle limit frame 16 passes through the connecting seat 6 and is fixed to the connecting seat 6 by bolts and nuts. This connection method is simple and strong. The side wall grooves of the middle limit frame 16 face the side wall grooves of the side frames 7, which can ensure the smooth movement of the stabilizing wheel 17 and the stabilizing rod 18.

[0030] The stabilizing wheel 17 is confined in the side frame 7, and its side wall round tube extends out from the side wall slot of the side frame 7. The stabilizing rod 18 is fixed to the round tube of the stabilizing wheel 17 by bolts, which can ensure the stability and reliability of the stabilizing wheel 17 and the stabilizing rod 18. The surface of the stabilizing rod 18 is smooth, and the contact end with the intermediate limit frame 16 is also smooth, which can reduce friction and wear and extend the service life of the equipment.

[0031] The lifting device 5 is fixedly mounted on the base 1 and the top seat 3 by fasteners, and is adapted to the connecting seat 6. The lifting device 5 can realize the lifting function of the connecting seat 6. In this way, the height and angle of the equipment can be adjusted according to different painting requirements to achieve the best painting effect.

[0032] Working process: First, move the automatic bridge painting equipment to the vicinity of the bridge to be painted. The position of the equipment can be easily adjusted by moving the wheels 4 to ensure that it is in a suitable working position; ensure that there is enough paint in the liquid storage tank 10. If not, it is necessary to add an appropriate amount of paint from the outside; check whether the infusion device 11, the spray nozzle 14, the hydraulic cylinder 8 and other key components are intact to ensure that they can work normally; adjust the distance between the side frame 7 and the middle limit frame 16 according to the width of the bridge. By controlling the extension and contraction of the hydraulic cylinder 8, the gap distance between the connecting seat 6 and the side frame 7 can be adjusted to adapt to bridges of different widths; adjust the height and angle of the entire painting equipment through the lifting device 5 to ensure that the spray nozzle 14 can accurately spray the surface of the bridge; start the infusion device 11 to transport the paint in the liquid storage tank 10 to the spray nozzle 14 through the infusion pipe 12; start the spray nozzle 14 to spray the paint evenly on the surface of the bridge. A complete paint delivery system is formed between the spray nozzle 14, the liquid storage tank 10 and the infusion device 11 to ensure that the paint can be continuously and evenly supplied to the spray nozzle 14; during the painting process, the stabilizing wheel 17 and the stabilizing rod 18 work together to maintain the stability of the side frame 7 during movement. The intermediate limit frame 16 limits the movement range of the side frame 7 to ensure the accuracy and uniformity of the painting; during the painting process, the uniformity and quality of the painting are checked regularly. If any problems are found, the parameters and position of the equipment are adjusted in time to ensure the best painting effect; according to the progress and needs of the painting, it may be necessary to replenish the paint or replace key components such as the spray nozzle 14 in time; when the surface painting of the bridge is completed, the spray nozzle 14 and the infusion device 11 are closed; the residual paint and dust on the equipment are cleaned to ensure the cleanliness and tidiness of the equipment; the equipment is moved to the next bridge to be painted or the storage location through the moving wheel 4; during the entire working process, the automatic bridge painting equipment achieves efficient and uniform painting effects through the collaborative work of various key components. At the same time, the stability and reliability of the equipment are also fully guaranteed to ensure the quality and efficiency of the painting.
