Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel structure processing equipment, and more specifically to a steel structure painting device. Background Technology
[0002] A steel structure painting device includes a frame with a base underneath. Multiple sets of support wheels supporting the steel structure are arranged sequentially from left to right on the frame. A paint container is also installed on the frame, and a spray pipe is connected to the container. The spray pipe is connected to a spray nozzle that can spray paint. In the prior art, the support wheels always support the steel structure. This creates a blind spot for the spray nozzle, resulting in a painting blind area on the steel structure, which affects product quality and also leads to low production efficiency. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a steel structure painting device that eliminates blind spots in the spray nozzles and achieves high production efficiency.
[0004] The technical solution of this utility model is implemented as follows: A steel structure painting device includes a frame, a base below the frame, and multiple sets of support wheels supporting the steel structure on the base. These support wheels are arranged sequentially from left to right on the frame. A paint container is also installed on the frame, and a spray pipe is connected to the container. The spray pipe is connected to a nozzle that can spray paint. The device is characterized by: a left-right directional slide rail on the frame, and rollers mounted on the slide rails. A spraying ring is connected below the rollers. The rollers run on the slide rails, causing the spraying ring to surround the steel structure from left to right. Multiple nozzles are evenly distributed around the spraying ring, facing the perimeter of the steel structure. Each set of support wheels is mounted on the base via a telescopic component, which is connected to a control device.
[0005] The beneficial effects of this utility model are: such a steel structure painting device has the advantages of no blind spots on the sprayed steel structure and high production efficiency. Attached Figure Description

[0009] The components include: 1. Device frame; 11. Base; 12. Slide rail; 2. Support wheel; 21. Front support wheel; 22. Rear support wheel; 3. Spray nozzle; 4. Roller; 5. Spraying ring; 6. Telescopic component; 7. Steel structure; 8. Container trough. Detailed Implementation
[0010] The present invention will be further described below with reference to the accompanying drawings.
[0011] like Figure 1 , 2 As shown in Figure 3, a steel structure painting device includes a frame 1, with a base 11 underneath the frame. Multiple sets of support wheels 2 support the steel structure on the base, arranged sequentially from left to right on the frame. A paint container 8 is also installed on the frame, and a spray pipe is connected to the container 8. A spray nozzle 3 is connected to the spray pipe and can spray paint. The device is characterized by: a left-right oriented slide rail 12 installed on the frame, and rollers 4 installed on the slide rails. A spraying ring 5 is connected below the rollers. The rollers run on the slide rails, causing the spraying ring to surround the steel structure from left to right. Multiple spray nozzles are evenly distributed around the spraying ring, facing the perimeter of the steel structure. Each set of support wheels is mounted on the base via a telescopic component 6, which is connected to a control device.
[0012] In this invention, the spraying ring moves around the steel structure from left to right. The spray nozzles spray paint. When the spraying ring is about to reach a certain set of support wheels, the control device can be manually operated. This control device is essentially a switch, causing the telescopic component of that set of support wheels to retract downwards, so that that set of support wheels no longer supports the steel structure. After the part of the steel structure supported by that set of support wheels is finished being sprayed, the control device is manually operated to raise the telescopic component, which then supports the steel structure again. The above operation is performed on each set of support wheels from left to right to complete the spraying of the steel structure, thus achieving the purpose of this invention. Because this invention uses multiple spray nozzles, it also has the advantage of high production efficiency.
[0013] The telescopic component can be, for example, a telescopic cylinder connected to an air pump, or a hydraulic cylinder connected to hydraulic oil, as long as it can rise or fall.
[0014] For example, the control device described is a switch leading to the telescopic cylinder; opening or closing the switch controls the raising and lowering of the telescopic component (telescopic cylinder). This is operable by those skilled in the art.
[0015] In one embodiment, the container is connected to a pressurizing device, such as an air compressor, to ensure that the paint sprayed from the nozzle has a certain spraying force.
[0016] In one embodiment, the roller 4 is connected to a roller motor, or the roller has a roller motor inside, to ensure that the roller moves in the left and right directions on the slide.
[0017] In one embodiment, each set of support wheels includes a front support wheel 21 installed at the front and a rear support wheel 22 installed at the rear to ensure the stability of the supporting steel structure.
[0018] In one embodiment, the steel structure is a steel pipe.
[0019] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
Claims
