Description

Technical Field

[0001] This application belongs to the field of building construction technology, specifically a steel pipe painting device. Background Technology

[0002] The main purpose of painting steel pipes is to provide corrosion protection, improve appearance, increase visibility, enhance wear resistance and insulation, and provide fire resistance, thereby extending the service life of steel pipes and meeting various application requirements.

[0003] For example, application CN210614156U discloses a steel pipe painting device, including a base, support plate, horizontal plate, first vertical plate, first motor, first conical block, first T-shaped groove, first T-shaped slider, second vertical plate, threaded rod, and second conical block. Through reasonable design, the first and second conical blocks form a steel pipe clamping structure. The device also includes a support plate, trapezoidal block, rack, second T-shaped groove, and second T-shaped slider. This structure constitutes a sliding platform for a paint storage tank. The sliding of the paint storage tank and the painting of the steel pipe are achieved through a roller brush, L-shaped plate, second motor, half gear, positioning groove, mounting plate, reducer, ball bearings, and second retaining ring. This steel pipe painting device eliminates the need for manual painting, ensures uniform paint application, avoids excessive paint waste, prevents harm to human health and environmental pollution, and has high work efficiency.

[0004] However, the application did not specify the painting of the inner wall of the steel pipe, and if the steel pipe was too long, the placement area was insufficient, limiting the conditions for painting. Utility Model Content

[0005] The purpose of this application is to provide a steel pipe painting device to solve the problems mentioned above, such as the lack of a corresponding steel pipe inner wall painting device and the limited painting conditions due to insufficient placement area if the steel pipe is too long.

[0006] The technical solution adopted in this application is as follows: a steel pipe painting device, including a reference pipe, a support pipe welded to one outer surface of the reference pipe, a stabilizing sleeve movably sleeved on the outer surface of the support pipe, a square hollow conduit welded to the outer surface of the stabilizing sleeve, a hollow sleeve movably sleeved on the outer surface of the square hollow conduit, and a roller brush provided on the outer surface of the hollow sleeve.

[0007] By adopting the above technical solution, the reference tube, as the main supporting component of the equipment, forms the main support with the support tube and the stabilizing sleeve. An internal channel is formed to facilitate the entry of paint. The support tube and the stabilizing sleeve rotate relative to each other, and the support tube can only allow air to circulate downwards. The equipment enters the inner diameter of the steel pipe, and the square hollow guide tube and hollow sleeve move relative to each other. The inner diameter is hollow, which facilitates the delivery of paint to the roller brush for painting, thereby ensuring continuous painting inside. As long as the pipeline is fixed and the load-bearing capacity meets the requirements, painting does not need to be carried out in a specific location, thus increasing the application scenarios.

[0008] In a preferred embodiment, a connecting rod is welded to the outer surface of the roller brush, and an adjusting member is welded to the outer surface of the end of the stabilizing sleeve away from the supporting tube. The outer surface of the output end of the adjusting member is fixedly connected to the connecting rod.

[0009] By adopting the above technical solution, the output end of the adjusting component extends the connecting rod outward, and the screw built into the adjusting component fixes the compression spring to complete the pressure adjustment, thereby facilitating painting.

[0010] In a preferred embodiment, a first motor is provided on the outer surface of the adjusting member, and a support plate is welded to the outer surface of the first motor.

[0011] By adopting the above technical solution, the first motor provides the mechanical power for rotation of the overall painting structure, and the support plate provides support for the first motor.

[0012] In a preferred embodiment, a support frame is movably sleeved on the outer surface of the support plate, and a roller is movably connected to the outer surface of the support frame at the end away from the support plate.

[0013] By adopting the above technical solution, the support frame ensures the stability of the equipment during painting, and the rollers minimize the impact on painting by rolling, thus ensuring the quality of painting.

[0014] In a preferred embodiment, a limiting groove is welded to the outer surface of the support plate, and a limiting plate is movably connected to the inner surface of the limiting groove.

[0015] By adopting the above technical solution, the limiting groove and limiting plate ensure the stability of the movement between the support plate and the support frame.

[0016] In a preferred embodiment, a positioning groove is provided on the side surface of the support frame, a fixing member is provided on the outer surface of the positioning groove, and a support frame is provided on the outer surface of the fixing member.

[0017] By adopting the above technical solution, the fastener is fixed in the positioning groove with corresponding screws, and the support frame is inserted into the fastener, which facilitates painting on the outer surface of the steel pipe.

[0018] In a preferred embodiment, an adjustment support is provided on the outer surface of the end of the reference tube away from the support tube, a second motor is fixedly connected to the outer surface of the adjustment support, and a drive wheel is fixedly connected to the outer surface of the output end of the second motor.

[0019] By adopting the above technical solution, the second motor drives the drive wheel to rotate, thereby attaching to the pipeline to move forward or backward. The adjustable support corresponding to the reference pipe adopts a deformable structure, which can rotate at an angle, making it convenient to support steel pipes with different inner diameters.

[0020] In a preferred embodiment, a conveying pipe is welded to the upper surface of the reference tube, and a storage tank is fixedly connected to the outer surface of the end of the conveying pipe away from the reference tube. A pressure pump is provided on the outer surface of the storage tank.

[0021] By adopting the above technical solution, the pressure pump increases the pressure, and the paint stored in the storage tank is flushed from the storage tank to the reference pipe through the delivery pipe.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application, the reference tube serves as the main supporting component of the equipment, forming a primary support with the support tube and stabilizing sleeve. An internal channel facilitates the entry of paint. The support tube and stabilizing sleeve rotate relative to each other, and the support tube allows airflow only downwards. The equipment enters through the inner diameter of the steel pipe, where the square hollow conduit and hollow sleeve move relative to each other. The hollow inner diameter facilitates the delivery of paint to the roller brush for painting, thus ensuring continuous painting inside. As long as the pipeline is fixed and meets the load-bearing requirements, painting does not need to be performed in specific locations, increasing the application scenarios.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Example:

[0031] Reference Figure 1-4 A steel pipe painting device includes a reference pipe 1, a support pipe 2 welded to one outer surface of the reference pipe 1, a stabilizing sleeve 3 movably sleeved on the outer surface of the support pipe 2, a square hollow conduit 4 welded to the outer surface of the stabilizing sleeve 3, a hollow sleeve 5 movably sleeved on the outer surface of the square hollow conduit 4, and a roller brush 6 provided on the outer surface of the hollow sleeve 5.

[0032] The reference pipe 1, as the main supporting component of the equipment, forms the main support with the support pipe 2 and the stabilizing sleeve 3. An internal channel is formed to facilitate the entry of paint. The support pipe 2 and the stabilizing sleeve 3 rotate relative to each other. The support pipe 2 can only allow air to flow downwards. The equipment enters through the inner diameter of the steel pipe. The square hollow conduit 4 and the hollow sleeve 5 move relative to each other. The inner diameter is hollow, which facilitates the delivery of paint to the roller brush 6 for painting. This ensures that painting is continuously carried out inside. As long as the pipeline is fixed and the load-bearing capacity meets the requirements, painting does not need to be carried out in a specific location, which increases the application scenarios.

[0033] Reference Figure 1-4 The outer surface of the roller brush 6 is welded with a connecting rod 7. The outer surface of the stabilizing sleeve 3 away from the support tube 2 is welded with an adjusting component 8. The outer surface of the output end of the adjusting component 8 is fixedly connected to the connecting rod 7.

[0034] The output end of the adjusting component 8 extends the connecting rod 7 outward, and the screw built into the adjusting component 8 fixes the compression spring to complete the pressure adjustment, thus facilitating painting.

[0035] Reference Figure 1-4 The outer surface of the adjusting component 8 is provided with a first motor 9, and a support plate 10 is welded to the outer surface of the first motor 9.

[0036] The first motor 9 provides the mechanical power for rotation of the overall painting structure, and the support plate 10 provides support for the first motor 9.

[0037] Reference Figure 1-4 A support frame 11 is movably sleeved on the outer surface of the support plate 10, and a roller 12 is movably connected to the outer surface of the support frame 11 at the end away from the support plate 10.

[0038] The support frame 11 ensures the stability of the equipment during painting, and the rollers 12 minimize the impact of painting by rolling, thus ensuring the quality of painting.

[0039] Reference Figure 1-4 A limiting groove 13 is welded to the outer surface of the support plate 10, and a limiting plate 14 is movably connected to the inner surface of the limiting groove 13.

[0040] The limiting groove 13 and the limiting plate 14 ensure stable movement between the support plate 10 and the support frame 11.

[0041] Reference Figure 1-4 The side surface of the support frame 11 is provided with a positioning groove 15, the outer surface of the positioning groove 15 is provided with a fastener 16, and the outer surface of the fastener 16 is provided with a support frame 17.

[0042] The fastener 16 is fixed to the positioning groove 15 with corresponding screws, and the support frame 17 is inserted into the fastener 16 to facilitate painting on the outer surface of the steel pipe.

[0043] Reference Figure 1-4 An adjustment support 18 is provided on the outer surface of the end of the reference tube 1 away from the support tube 2. A second motor 19 is fixedly connected to the outer surface of the adjustment support 18. A drive wheel 20 is fixedly connected to the outer surface of the output end of the second motor 19.

[0044] The second motor 19 drives the drive wheel 20 to rotate, thereby attaching to the pipeline to move forward or backward. The adjustable support 18 adopts a deformable structure corresponding to the reference pipe 1, which can rotate at an angle to facilitate support for steel pipes with different inner diameters.

[0045] Reference Figure 1-4 A conveying pipe 21 is welded to the upper surface of the reference pipe 1. A storage tank 22 is fixedly connected to the outer surface of the end of the conveying pipe 21 away from the reference pipe 1. A pressure pump 23 is installed on the outer surface of the storage tank 22.

[0046] The pressurizing pump 23 pressurizes the paint stored in the storage tank 22 and pushes it from the storage tank 22 to the reference pipe 1 through the delivery pipe 21.

[0047] The implementation principle of an embodiment of a steel pipe painting device according to this application is as follows:

[0048] During use, painting is performed on the inner or outer surface of the steel pipe as needed. When painting the inner wall, the fixing piece 16 is removed, and the springs at both ends of the support plate 10 pop outward. Similarly, the output end of the adjusting piece 8 extends the connecting rod 7 outward. The difference is that the screw inside the adjusting piece 8 fixes the compression spring to complete the pressure adjustment, thus facilitating painting. Correspondingly, the hollow sleeve 5 is extended outward. The square hollow guide tube 4 and the hollow sleeve 5 are hollow in the middle, forming a channel with the stabilizing sleeve 3. The support tube 2 and the stabilizing sleeve 3 rotate relative to each other. The support tube 2 can only allow air to flow downward. After the steel pipe to be painted is fixed, the equipment enters the inner diameter of the steel pipe, and the second motor 19 drives the drive wheel 20 to move forward or backward. The adjusting support 18 adopts a formable shape corresponding to the reference tube 1. The variable structure allows for angle rotation, facilitating support for steel pipes of different inner diameters. The pressure pump 23 pressurizes the paint stored in the storage tank 22, which is then pumped from the storage tank 22 to the reference pipe 1 through the delivery pipe 21. The first motor 9 rotates, driving the adjusting component 8, which in turn drives the entire painting structure to rotate. When the paint is applied from below, the support pipe 2, stabilizing sleeve 3, square hollow conduit 4, and hollow sleeve 5 provide a path for the roller brush 6 to touch up the paint. The roller brush 6 in other positions applies a stable and uniform coating. When external painting is required, the support frame 11 is brought close and fixed to the positioning groove 15 by the fixing component 16. The support frame 17 provides support, and the support frame 11 is placed horizontally for painting above the outer pipe. When painting below the outer pipe, the support frame 11 is rotated 180 degrees for painting.
