Description

Technical Field

[0001] This utility model relates to the field of pipeline coating technology, and in particular to a rapid coating device for anti-corrosion coating on the surface of high-pressure pipelines. Background Technology

[0002] In industrial instruments, laboratory equipment, medical devices and other scenarios, high-pressure pipelines are generally small-diameter and lightweight metal pipes. The metal pipes need to be coated with anti-corrosion coatings to improve their service life. The core goal of applying anti-corrosion coatings is to form a uniform, dense and strongly adhered coating to resist corrosion, wear and harsh environments.

[0003] Before spraying, the pipes need to be pre-treated by grinding and cleaning. Even after pre-treatment, dust will still fall on the surface of the pipes before they enter the spraying workshop. If the dust is not cleaned, it will affect the adhesion of the coating. In actual production, for pipes that have been stored for a long time and have a lot of dust on the surface, manual cleaning is generally used to remove the surface dust and ensure the adhesion of the coating. This is not only time-consuming and labor-intensive, but also difficult to guarantee a thorough cleaning effect. When applying the anti-corrosion layer, the pipes are usually fixed in the spraying workshop with clamps. During spraying, the spray gun needs to be moved multiple times by the operator to spray from all directions, resulting in low spraying efficiency.

[0004] Therefore, this application provides a rapid coating device for anti-corrosion coating on the surface of high-pressure pipelines to solve the problems mentioned in the background art. Summary of the Invention

The pneumatic claws of the two clamping components extend into the inner cavities at both ends of the pipeline along the horizontal axis to clamp and fix the pipeline; the pulley A of the clamping component is vertically connected to the vertically arranged pulley B via a belt to form a vertical transmission connection, and the pulley B is connected to the motor A via a rotating shaft, and the motor A is used to drive the pneumatic claws to rotate.

[0007] A further improvement of the present invention is that the clamping assembly also includes an L-shaped bracket set on the top surface of the horizontal slide module, a cylinder is set on the outside of the bracket, the telescopic rod of the cylinder extends through to the inside of the bracket, a pulley A is movably mounted on the outside of the telescopic rod, and a pneumatic claw is set on the inner side of the pulley A.

[0008] A further improvement of the present invention is that the pneumatic gripper also includes three fixing blocks evenly arranged on the inner side of the vertical pulley A. The fixing blocks are connected to the middle of the support block through a fixing plate shaft, and the bottom end of the support block is connected to the end of the telescopic rod shaft.

[0009] A further improvement of this utility model is that a pulley B is positioned directly below the pulley A at the front end of the flatbed vehicle, and pulley B is connected to pulley A by a belt. The horizontal axis of pulley B is connected to motor A on the outside of the bracket.

[0010] A further improvement of the present invention is that the horizontal slide module also includes a U-shaped base horizontally set on the top surface of the flatbed, a lead screw horizontally set in the middle of the base body, a ball slider sleeved on the lead screw body, a horizontal fixing plate set on the top surface of the ball slider, and limit sliders set on both sides of the bottom surface of the fixing plate. The limit sliders are movably nested on the limit rail body, and the limit rail is set on both sides of the top surface of the base.

[0011] A further improvement of this utility model is that: one end of the lead screw is connected to motor B, and motor B drives the lead screw to rotate and drives the ball slider to move horizontally.

[0012] A further improvement of the present invention is that the soot blowing device also includes an arched protective cover, and several high-pressure air pipes are arranged parallel to each other along the horizontal axis on the inner wall of the protective cover, and several air outlet holes are opened on the wall of the high-pressure air pipes.

[0013] A further improvement of this utility model is that both the spraying device and the drying device also include an arched protective cover.

[0014] A further improvement of this utility model is that the diameter of the protective cover is larger than the outer diameter of the pipe, and the length of the protective cover is larger than the length of the pipe.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] 1. This utility model provides a rapid coating device for anti-corrosion coating on the surface of high-pressure pipelines. The pneumatic claw of the clamping component expands and supports the pipeline. The clamping component can rotate via a pulley. The rotating pipeline allows the spraying operation to be carried out continuously, reducing the need for manual rotation of the pipeline or adjustment of the spraying angle.

The automated dust blowing device reduces the manual cleaning process, lowers labor intensity and labor costs, and the arched protective cover can save space and improve space utilization while adapting to pipeline size.

[0031] The present invention will be further explained below with reference to specific embodiments.

[0032] like Figures 1-6As shown, this embodiment provides a rapid coating device for anti-corrosion coating on the surface of high-pressure pipelines, including a track 1, a movable flatbed 2 mounted on the track 1 body, and a soot blowing device 3, a spraying device 4, and a drying device 5 sequentially mounted above the track 1 behind the flatbed 2; two horizontal sliding table modules 6 are symmetrically mounted on the top surface of the flatbed 2 body, and clamping components 7 are symmetrically mounted on the two horizontal sliding table modules 6 bodies, with pneumatic claws 75 of the two clamping components 7 extending into the inner cavities of both ends of the pipeline 8 along the horizontal axis to clamp and fix the pipeline 8; the clamping components... The pulley A74 of component 7 is vertically connected to the pulley B76, which is arranged vertically, via belt 77. Pulley B76 is connected to motor A78 via a shaft, and motor A78 drives the pneumatic gripper 75 to rotate. Specifically, the bottom surface of the flatbed trolley 2 is equipped with rollers (not shown in the figure) adapted to slide along the track. The flatbed trolley 2 can move horizontally along track 1, sequentially passing through the dust blowing device 3, spraying device 4, and drying device 5 to complete the processes of dust blowing, coating the anti-corrosion layer, and drying the anti-corrosion layer on the pipe 8. Two horizontal sliding molds... Group 6 is fixed horizontally to the center of both ends of the flatbed trolley 2, used to adjust the horizontal distance between the two clamping components 7, facilitating the insertion or removal of the pneumatic claws 75 into or from the inner cavities of both ends of the pipe 8, enabling automatic clamping and disassembly. The pneumatic claws 75 are controlled to open or retract by cylinder 72. The telescopic rod 73 of cylinder 72 extends inward, and the pneumatic claws 75 open to tightly adhere to the inner wall of the pipe 8 to support and fix the pipe 8. Simultaneously, the pneumatic claws 75 are mounted on pulley A74, which is connected to pulley B76 via belt 77. The pulley B76 is connected to the motor A78 via a rotating shaft. The motor A78 drives the pulley B76 to rotate, and the pulley B76 drives the pulley A74 to rotate via the belt 77. The pulley A74 drives the pipe 8 to rotate via the pneumatic gripper 75. The rotating pipe 8 allows the spraying operation to be carried out continuously, reducing the need for manual rotation of the pipe 8 or adjustment of the spraying angle. The spraying equipment can maintain a fixed position relative to the pipe 8, which enables the anti-corrosion coating to be evenly sprayed on all parts of the outer wall of the pipe 8, thus improving the spraying efficiency.

[0033] like Figures 2-4As shown, in this embodiment, the clamping assembly 7 further includes an L-shaped bracket 71 disposed on the top surface of the horizontal slide module 6. A cylinder 72 is disposed on the outside of the bracket 71, and the telescopic rod 73 of the cylinder 72 extends through to the inside of the bracket 71. A pulley A74 is movably mounted on the outside of the telescopic rod 73, and a pneumatic claw 75 is disposed on the inner side of the pulley A74. The pneumatic claw 75 also includes three fixing blocks 751 evenly disposed vertically on the inner side of the pulley A74. The fixing blocks 751 are axially connected to the middle of the support block 753 through a fixing plate 752, and the bottom end of the support block 753 is axially connected to the end of the telescopic rod 73. Specifically, the bracket 71 is an L-shaped plate structure, and the bracket 71 is vertically screwed to the top surface of the fixing plate 64 of the horizontal slide module 6 to support and fix the cylinder 72, pulley A74, etc. The end of the telescopic rod 73 has a Y-shaped structure. The bottom of the support block 753 is fixedly connected to the three branches of the Y-shaped structure. The support block 753 has an irregular shape. The top of the support block 753 is a semi-cylindrical structure. The outer side of the top of the support block 753 is an arc structure to better fit against the inner wall of the pipe 8. The cylinder 72 is fixed on the outside of the bracket 71. When air enters the cylinder 72, the telescopic rod 73 extends outward, which drives the three support blocks 753 to expand outward under the limitation of the fixing plate 752. The top of the three support blocks 753 expands outward to fit the inner wall of the pipe 8 to clamp and fix the pipe 8. After the cylinder 72 is depressurized, the three support blocks 753 move closer to each other and contract. At this time, the diameter of the circle formed by the three support blocks 753 is smaller than the inner diameter of the pipe 8, which makes it easier for the three support blocks 753 to be inserted into the inner cavity of the pipe 8.

[0034] like Figures 2-3 As shown, in this embodiment, a pulley B76 is positioned directly below the pulley A74 at the front end of the flatbed trolley 2. The pulley B76 is connected to the pulley A74 via a belt 77. The pulley B76 is horizontally connected to a motor A78 on the outside of the bracket 71. Specifically, a motor A78 is fixed on the front bracket 71. The motor A78 drives the pulley B76 to rotate, and the pulley B76 drives the pulley A74 to rotate via the belt 77. The pulley A74 drives the pipe 8 to rotate via a pneumatic gripper 75, so that the anti-corrosion coating is evenly sprayed on various parts of the outer wall of the pipe 8.

[0035] like Figure 2 , Figure 3 , Figure 5As shown, in this embodiment, the horizontal slide module 6 also includes a U-shaped base 61 horizontally disposed on the top surface of the flatbed trolley 2. A lead screw 62 is horizontally disposed in the middle of the base 61 body. A ball bearing slider 63 is sleeved on the lead screw 62 body. A horizontal fixing plate 64 is disposed on the top surface of the ball bearing slider 63. Limiting sliders 65 are disposed on both sides of the bottom surface of the fixing plate 64. The limiting sliders 65 are movably nested on the limiting rail 66 body. The limiting rail 66 is disposed on both sides of the top surface of the base 61. One end of the lead screw 62 is connected to a motor B67. The motor B67 drives the lead screw 62 to rotate and drives the ball bearing slider 63 to move horizontally. Specifically, the motor B67 drives the lead screw 62 to rotate, thereby causing the ball bearing slider 63 to move horizontally on the lead screw 62, thereby causing the clamping assembly 7 to move horizontally, realizing automatic adjustment of the distance between the two clamping assemblies 7, which facilitates the clamping and disassembly of the pipe 8.

[0036] like Figure 1 , Figure 6 As shown, in this embodiment, the dust blowing device 3 also includes an arched protective cover 31. Several high-pressure air pipes 32 are arranged parallel to each other along the horizontal axis on the inner wall of the protective cover 31. Several air outlets 33 are opened on the pipe wall of the high-pressure air pipes 32. The spraying device 4 and the drying device 5 also include an arched protective cover 31. The diameter of the protective cover 31 is larger than the outer diameter of the pipe 8, and the length of the protective cover 31 is larger than the length of the pipe 8. Specifically, the flatbed trolley 2 can move horizontally along the track 1 and pass through the dust blowing device 3, the spraying device 4 and the drying device 5 in sequence to complete the dust blowing, anti-corrosion coating and anti-corrosion drying processes of the pipe 8 in sequence. The protective cover 31 is slightly larger than the length of the pipe 8. The parallel high-pressure air pipes 32 distribute compressed air evenly to various parts of the outer wall of the pipe 8, thereby effectively removing dust and impurities.

[0037] This utility model provides a rapid coating device for anti-corrosion coating on the surface of high-pressure pipelines. The working principle is as follows: During use, the operator first drives the ball bearing slider 63 outward via motor B67, increasing the distance between the two opposing supports 71. Then, the pipeline 8 is placed between the two supports 71. Next, the ball bearing slider 63 is driven inward via motor B67, causing the pneumatic claws 75 to enter the inner cavities at both ends of the pipeline 8. Then, the air intake system of cylinder 72 is activated, and the telescopic rod 73 extends outward, causing the three support blocks 753 to expand outward under the constraint of the fixing plate 752. The tops of the three support blocks 753 expand outward to fit the inner wall of the pipeline 8, clamping and fixing the pipeline 8. Simultaneously, motor A78 starts to drive the pipeline 8 to rotate. Then, the flatbed trolley 2 can move horizontally along track 1, sequentially passing through the dust blowing device 3, the spraying device 4, and the drying device 5 to complete the processes of dust blowing, anti-corrosion coating, and drying of the anti-corrosion layer on the pipeline 8.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
