Description

Technical Field

[0001] This invention relates to the field of steel structure beam processing technology, and more specifically to a steel structure beam spraying device and a steel structure beam spraying method. Background Technology

[0002] Steel structural beams have multiple sides, for example, four sides. The exterior of the steel structural beam has a protective layer, which is formed by the curing of sprayed paint, such as oil paint. The equipment used to form this protective layer on the steel structural beam is a steel structural beam spraying device.

[0003] The steel structure beam spraying device includes a frame with a spray head on it. In use, the spray head moves forward and the paint sprayed from the spray head lands on the side of the steel structure beam.

[0004] In existing technologies, the paint sprayed from the spray head is evenly distributed across the sides of the steel structure beam. However, in actual use, the paint layer on the edges (near the corners) of the steel structure beam is more susceptible to damage, such as from bumps or scratches. This method cannot adequately protect the steel structure beam and is inconvenient to use. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a steel structure beam spraying device and method that can form a thicker coating layer on the side edges of steel structure beams, effectively protect them, and is easy to use.

[0006] The technical solution of the steel structure beam spraying device of the present invention is implemented as follows: The steel structure beam spraying device includes a device frame, on which a spraying head is provided. In use, the spraying head sprays paint onto the side of the steel structure beam and moves forward. The characteristic is that the paint sprayed by the spraying head onto the steel structure beam near the corner is more paint per unit length than the paint sprayed per unit length at other parts.

[0007] Specifically, the spray head has spray holes, and the spray holes on the spray head near the corners of the steel structure beam are more densely packed than those in other parts.

[0008] Specifically, the spray head has spray holes, and the spray holes on the spray head facing the steel structure beam near the corners have a larger diameter than the holes in other parts.

[0009] Furthermore, there is a temperature regulating component in front of the spray head, which makes the temperature of the middle part of the steel structure beam (the part away from the corners) higher than that of the side part of the steel structure beam.

[0010] Specifically, the temperature regulating component includes a heating component and a cooling component. The heating component acts on the middle part of the steel structure beam, and the cooling component acts on the side part of the steel structure beam.

[0011] Specifically, the heating element is a heating wire, which has higher power when facing the middle part of the steel structure beam and lower power when deviating from the middle part of the steel structure beam.

[0012] Specifically, the cooling component is a refrigeration device, which has a cold air output pipe and is connected to an airflow distribution pipe. The airflow distribution pipe has multiple air outlets facing the side of the steel structure beam, and the diameter of the multiple air outlets facing the side of the steel structure beam is larger than the diameter of the holes away from the side of the steel structure beam.

[0013] Furthermore, the temperature regulating component ensures a smooth transition from low to high temperatures on the surface of the steel structure beam.

[0014] Furthermore, the device frame also has a reel with a release line, and a pressure wheel is also installed on the device frame. The pressure wheel is located on the side of the steel structure beam (near the corner). In use, the pressure wheel can make the release line of the reel buried in the edge of the side of the steel structure beam (near the corner).

[0015] Furthermore, the device frame has rollers underneath, a paint bucket on the device frame, the paint bucket is connected to a spray head via an output pipe, and a pump is installed in the middle of the output pipe.

[0016] Furthermore, the device frame is also equipped with a vibration device, which has a vibration output head. In use, the vibration output head acts on the back of the spraying area of ​​the steel structure beam.

[0017] The technical solution of the steel structure beam spraying method of the present invention is as follows: In the process of spraying, more paint is sprayed on the surface of the steel structure beam near the edge (near the corner).

[0018] Furthermore, before spraying the steel structure beam, the temperature on both sides of the steel structure beam surface is lowered.

[0019] Furthermore, during the spraying of the steel structure beam, wires are also embedded on the side of the steel structure beam surface.

[0020] Furthermore, after the steel structure beam is sprayed, vibrations are also generated behind the sprayed area.

[0021] The beneficial effects of this invention are: such a steel structure beam spraying device and method have the advantages of forming a thicker coating layer on the side edges of the steel structure beam and ease of use. The resulting steel structure beam has the advantage of greater impact resistance on its side edges. Attached Figure Description

[0029] The following description, in conjunction with the accompanying drawings, illustrates one step of the present invention.

[0030] like Figure 1 , 3 As shown in Figures 4 and 5, the steel structure beam spraying device includes a device frame 1 with a spray head 2 on the device frame. In use, the spray head sprays paint onto the side of the steel structure beam 3 and moves forward. The characteristic is that the paint sprayed by the spray head onto the steel structure beam near the corner is more paint per unit length than the paint sprayed per unit length at other parts.

[0031] When the steel structure beam spraying device of the present invention is used, more paint can be sprayed on the side of the steel structure beam near the edge, that is, near the corner, so that the paint layer on the side of the steel structure beam near the edge is thicker, thus achieving the purpose of the present invention.

[0032] Specifically, the spray head has spray holes 21, and the spray holes on the spray head near the corner of the steel structure beam are more densely packed than those in other parts.

[0033] Specifically, the spray head has spray holes 21, and the diameter of the spray holes on the spray head facing the steel structure beam near the corner is larger than that of the holes in other parts.

[0034] Furthermore, there is a temperature regulating component 4 in front of the spray head, which makes the temperature of the middle part of the steel structure beam, that is, the part away from the corners, higher than the temperature of the side part of the steel structure beam.

[0035] The middle part of the side of the steel structure beam has a higher temperature, which makes the paint on this part flow better and is conducive to the leveling of the paint; the side of the steel structure beam near the edge has a lower temperature, which makes the paint on this part less likely to flow and is conducive to the solidification of thicker paint, that is, it will not run.

[0036] Specifically, the temperature regulating component includes a heating component 41 and a cooling component 42. The heating component acts on the middle part of the steel structure beam, and the cooling component acts on the side part of the steel structure beam.

[0037] Specifically, the heating element is a heating wire, which has higher power when facing the middle part of the steel structure beam and lower power when deviating from the middle part of the steel structure beam.

[0038] For example, the heating wire is thicker in the middle and thinner at both ends, so that the middle part of the side of the steel structure beam receives more heat and has a higher temperature, while the temperature is slightly lower in the middle part of the side of the steel structure beam further away from the middle part.

[0039] Specifically, the cooling component is a refrigeration device, which has a cold air output pipe 421. The cold air output pipe is also connected to an airflow distribution pipe 422. The airflow distribution pipe has multiple air outlets 4221 facing the side of the steel structure beam. The diameter of the multiple air outlets facing the side of the steel structure beam is larger than the diameter of the holes away from the side of the steel structure beam.

[0040] Furthermore, the temperature regulating component ensures a smooth transition from low to high temperatures on the surface of the steel structure beam.

[0041] Furthermore, the device frame also has a reel 51 with a release line 52, and a pressure wheel 53 is also installed on the device frame. The pressure wheel is located on the side of the steel structure beam (near the corner). In use, the pressure wheel can make the release line of the reel buried in the side edge of the steel structure beam (near the corner).

[0042] This invention allows for the embedding of wires on the side of the steel structure beam surface, so that the wires are concealed in the paint, increasing the overall integrity of the paint in that area.

[0043] Furthermore, the device frame has rollers 11 below it and paint buckets 12 on it. The paint buckets are connected to the spray head via an output pipe 14, and a pump 13 is installed in the middle of the output pipe.

[0044] Furthermore, a vibration device 6 is also installed on the device frame. The vibration device has a vibration output head 61. In use, the vibration output head acts on the back of the spraying part of the steel structure beam.

[0045] This design allows for better smoothness of the coating layer on the surface of the steel structure beam, which is beneficial for the coating to spread evenly.

[0046] The technical solution of the steel structure beam spraying method of the present invention is as follows: In the process of spraying, more paint is sprayed on the surface of the steel structure beam near the edge (near the corner).

[0047] Furthermore, before spraying the steel structure beam, the temperature on both sides of the steel structure beam surface is lowered.

[0048] Furthermore, during the spraying of the steel structure beam, wires are also embedded on the side of the steel structure beam surface.

[0049] Furthermore, after the steel structure beam is sprayed, vibrations are also generated behind the sprayed area.

[0050] The above-mentioned technical solutions, embodiments, and beneficial effects of steel structure beam spraying devices and methods can be explained or understood in relation to each other.

[0051] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
