Description

Technical Field

[0001] This utility model belongs to the technical field of spraying equipment, and in particular relates to a rust-proof paint spraying device for steel structure surfaces. Background Technology

[0002] Steel structure painting is an important process in steel structure construction, mainly used to protect steel structure materials from natural factors such as oxidation, corrosion, and rust, thereby extending the service life of the steel structure building. There are two methods for spraying steel structure paint: manual spraying and mechanical spraying. Manual spraying is inefficient, produces inconsistent paint quality, and the sprayed materials can be harmful to workers. Mechanical spraying involves moving the steel components through the spraying equipment; after spraying, the components need to be removed from the equipment promptly, which can easily damage the paint surface and affect product quality. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a rust-proof paint spraying device for steel structure surfaces, which effectively solves the problem of poor spraying quality.

[0004] The technical solution to the technical problem is as follows: it includes a vehicle body, a U-shaped frame that is lifted and connected to the vehicle body, a cover plate that is hinged to the U-shaped frame, a steel component in the middle of the U-shaped frame, first electric push rods installed on the left, right and lower sides of the U-shaped frame, a second electric push rod installed on the cover plate in a vertical direction, and telescopic rods that move toward or away from the steel component on both the first and second electric push rods. A tank is installed on the telescopic rod, and a spray nozzle facing the steel component is installed on the tank. A paint pump is installed on the vehicle body, and the paint pump is connected to the tank via a pipeline.

[0005] Preferably, a vertical hydraulic cylinder is installed on the vehicle body, and the telescopic end of the hydraulic cylinder is fixedly connected to the bottom end of the U-shaped frame.

[0006] Preferably, a handle is installed on one side of the cover plate, a protrusion is fixed at the upper end of the U-shaped frame, and a through groove corresponding to the protrusion is provided on the cover plate.

[0007] Preferably, the nozzle is equipped with a remote control switch.

[0008] Preferably, the lower end of the vehicle body is equipped with multiple drive wheels.

[0009] Preferably, the vehicle body is equipped with a storage battery.

[0010] This invention offers the following advantages over traditional equipment: the cover plate and the U-shaped frame are hinged. When the cover plate is open, the steel component can enter or leave the U-shaped frame by raising and lowering it. When the steel component is in the U-shaped frame, the cover plate is closed. The spraying distance between each nozzle and the steel component is adjusted by the first and second electric push rods. It offers good flexibility and is suitable for spraying steel components of different specifications. It enables spraying of steel components in all directions, including up, down, left, and right. By moving the vehicle body forward and backward, it can perform mobile spraying for rust prevention on steel components. It has a wide coverage area, high spraying quality, high degree of automation, simple operation, and reduces the inhalation of harmful substances by workers. Attached Figure Description

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 2 A rust-preventive paint spraying device for steel structure surfaces is provided, comprising a vehicle body 1, a U-shaped frame 2 connected to the vehicle body 1 in a lifting manner, a cover plate 3 hinged to the U-shaped frame 2, a steel component 4 located in the middle of the U-shaped frame 2, first electric push rods 5 installed on the left, right and lower sides of the U-shaped frame 2, a second electric push rod 6 installed vertically on the cover plate 3, both the first electric push rod 5 and the second electric push rod 6 having telescopic rods 7 that move toward or away from the steel component 4, a tank 8 installed on the telescopic rod 7, a spray nozzle 9 installed on the tank 8 facing the steel component 4, and a paint pump 10 installed on the vehicle body 1, the paint pump 10 being connected to the tank 8 via a pipeline.

[0016] A vertical hydraulic cylinder 11 is installed on the vehicle body 1, and the telescopic end of the hydraulic cylinder 11 is fixedly connected to the bottom end of the U-shaped frame 2.

[0017] To facilitate the opening and closing of the cover plate 3, a handle 12 is installed on one side of the cover plate 3, a protrusion 13 is fixed at the upper end of the U-shaped frame 2, and a through groove corresponding to the protrusion 13 is provided on the cover plate 3.

[0018] The nozzle 9 is equipped with a remote control switch 14.

[0019] The lower part of the vehicle body 1 is equipped with multiple drive wheels.

[0020] The vehicle body 1 is equipped with a storage battery 15, which provides power to the electric push rod, the paint pump 10 and the drive wheels.

[0021] In use, when the steel component 4 needs to be painted, the drive wheel power is turned on, and multiple drive wheels move the vehicle body 1 to below the steel component 4. The cover plate 3 is opened by the handle 12. The cover plate 3 is hinged to the U-shaped frame 2, and the top of the U-shaped frame 2 is in an open state. The hydraulic cylinder 11 is activated, and the hydraulic cylinder 11 moves the U-shaped frame 2 upward. When the steel component 4 is in the middle position of the U-shaped frame 2, the hydraulic cylinder 11 is closed, and then the cover plate 3 is closed. The through groove is locked onto the protrusion 13. The first electric push rod 5 and the second electric push rod 6 are activated. According to the specifications of the steel component 4, the position of each spray nozzle 9 is adjusted, which is flexible. The paint pump 10 is then activated. The anti-rust coating is pressurized through the pipeline into the tank 8. Then, the remote control switch 14 is activated, and the nozzles 9 spray the anti-rust coating onto the surface of the steel component 4. Multiple nozzles 9 spray simultaneously, and the steel component 4 can be sprayed from all sides. The drive wheels are activated, and the drive wheels move the vehicle body 1 in the forward and backward directions, so that multiple nozzles 9 can move and spray on the surface of the steel structure, expanding the spraying range. The automation level is high and the spraying effect is good. After the spraying is completed, the cover plate 3 is opened, and the hydraulic cylinder 11 drives the U-shaped frame 2 to move downward. The vehicle body 1 can then move the U-shaped frame 2 away from the steel component 4. The operation is simple and does not require moving the steel component 4, so that the steel component 4 can be painted from all directions.

[0022] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
