Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel pipe painting device for construction. Background Art

[0002] In the field of construction, steel pipes are widely used as important building materials, and their surface painting has multiple important meanings. On the one hand, painting can form a protective layer on the surface of the steel pipe, effectively preventing the steel pipe from rusting and corrosion, greatly extending the service life of the steel pipe and reducing construction costs; on the other hand, painting can make the steel pipe more beautiful, meet the needs of building decoration, and improve the overall beauty of the building.

[0003] Most steel pipe painting devices are equipped with an annular painting frame, and the steel pipe passes through the inside of the annular painting frame. As the steel pipe moves, the effect of spraying paint on the surface of the steel pipe is achieved. However, during the painting process, the staff first needs to clamp and fix the steel pipe by a clamping mechanism. When clamping the steel pipe, the staff needs to hold the steel pipe and wait for the clamping mechanism to operate and clamp and fix the steel pipe. It is difficult to pre-fix and clamp the steel pipe quickly, which affects the portability of the operation. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-Figure 5As shown, a steel pipe painting device for construction includes a workbench 1 and a paint spraying room 2 arranged at the upper end of the workbench 1, a box door 3 is hingedly provided on one side of the paint spraying room 2, a paint spraying rack 11 for paint spraying operation is slidably provided inside the paint spraying room 2, a screw rod 12 for driving the paint spraying rack 11 to move is rotatably provided inside the paint spraying room 2, the paint spraying rack 11 is threadedly connected with the screw rod 12 through a connecting block, a first motor 8 for driving the screw rod 12 to rotate is provided on the outside of the paint spraying room 2, a controller 5 is provided on the upper end of the workbench 1, and a paint storage tank is provided on the outside of the paint spraying room 2 4. The paint spraying rack 11 is connected with the paint storage tank 4 through a pipeline. A clamping assembly for clamping the steel pipe to be painted and driving it to rotate is provided inside the paint spraying room 2. After the clamping assembly clamps and fixes the steel pipe to be painted, it can drive it to rotate, and then the paint spraying rack 11 performs the painting operation. Under the driving action of the first motor 8, the paint spraying rack 11 moves. During the rotation of the steel pipe to be painted, the moving paint spraying operation of the paint spraying rack 11 is cooperated to achieve the effect of spraying paint on the surface of the steel pipe, thereby effectively improving the work efficiency.

[0030] Furthermore, the clamping assembly includes two conical blocks 13 and an electric push rod 10 arranged on the outside of the paint spraying room 2. The telescopic end of the electric push rod 10 movably penetrates into the paint spraying room 2 and is provided with a connecting seat 20. One of the conical blocks 13 is rotatably connected to the connecting seat 20, and one of the conical blocks 13 is rotatably connected to the inner wall of the paint spraying room 2 through the rod body. A second motor 9 for driving the rod body to rotate is provided on the outside of the paint spraying room 2. The second motor 9 is electrically connected to the controller 5. When in use, the steel pipe to be painted is first placed between the two conical blocks 13, and then the electric push rod 10 is started. The electric push rod 10 extends out to drive one of the conical blocks 13 to move, so that the steel pipe approaches the other conical block 13, that is, the distance between the two conical blocks 13 is gradually shortened, thereby achieving the effect of clamping the steel pipe. After the steel pipe is clamped and fixed, the second motor 9 is started to drive the rod body to rotate, and the rotation of the rod body drives the clamped and fixed steel pipe to rotate, thereby effectively ensuring the uniformity of paint spraying on the surface of the steel pipe.

[0031] Furthermore, the rod body includes a rotating sleeve 17 rotatably connected to the inner wall of the spray booth 2 and a spline shaft 15 slidably arranged inside the rotating sleeve 17, one end of the spline shaft 15 is fixedly connected to the tapered block 13, and the other end of the spline shaft 15 is connected to the inner wall of the rotating sleeve 17 through a spring 16. A pressure sensor 19 is fixedly provided at one end of the spline shaft 15 near the spring 16, and the pressure sensor 19 is electrically connected to the second motor 9. In the process of clamping the steel pipe, the staff can make one end of the steel pipe initially squeeze the tapered block 13 connected to the rod body, so that the distance between the two tapered blocks 13 is increased. Then the steel pipe can be placed between the two conical blocks 13. Under the action of the spring 16 resetting, the steel pipe can be initially positioned. Then the electric push rod 10 is extended to drive the steel pipe to move. In this process, the spline shaft 15 will slide into the rotating sleeve 17, so that the spring 16 is compressed. As the spline shaft 15 slides into the rotating sleeve 17, the pressure sensor 19 is squeezed against the inner wall of the rotating sleeve 17. Then the signal is fed back to the controller 5. The controller 5 controls the second motor 9 to start, so that the second motor 9 starts automatically, thereby improving the working efficiency.

[0032] Furthermore, a fixed ring 18 is fixedly provided on the outer side of the rotating sleeve 17, and a telescopic sleeve 14 is provided on the outer side of the spline shaft 15. One end of the telescopic sleeve 14 is fixedly connected to the conical block 13, and the other end of the telescopic sleeve 14 is fixedly connected to the surface of the fixed ring 18. Under the action of the telescopic sleeve 14, the paint is effectively prevented from adhering to the surface of the spline shaft 15 during the painting operation, thereby affecting the telescopic sliding of the spline shaft 15.

[0033] Furthermore, a telescopic sleeve 14 is also sleeved on the outside of the telescopic end of the electric push rod 10, and one end of the telescopic sleeve 14 is fixedly connected to the connecting seat 20, and the other end is fixedly connected to the inner wall of the paint spraying room 2. Under the action of the telescopic sleeve 14, the telescopic end of the electric push rod 10 is protected to prevent paint from adhering to the telescopic end surface of the electric push rod 10.

[0034] Furthermore, a rectangular frame 6 is fixedly provided inside the spray paint room 2, a magnet 7 which is magnetically attracted to the rectangular frame 6 is fixedly embedded on the inner side of the door 3, and a handle is fixedly provided on the outer side of the door 3. When the door 3 is in a closed state, the magnetic attraction between the magnet 7 and the rectangular frame 6 ensures the stability of the closing of the door 3, and at the same time, it is convenient for the staff to quickly open the door 3 by pulling the handle.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
