Description

Technical Field

[0001] This utility model relates to the field of coupling painting, specifically a device for painting oil pipe couplings. Background Technology

[0002] Tubing couplings are steel fittings that fit over the ends of two tubing pipes and connect them quickly via threads. They are the core components of oil and gas well tubing string connections, ensuring sealing and strength. The precision thread design on the inner and outer walls ensures the sealing performance after tubing connection, preventing oil and gas leakage, while also enhancing the overall tensile and compressive strength of the tubing string.

[0003] Spraying paint on oil pipe couplings can form an isolation layer that resists the corrosion of oil, gas, moisture, and chemical media, extending their service life under complex working conditions. Different colors of paint can be used to indicate the specifications, materials, or usage scenarios of the couplings, making it easier for construction personnel to quickly identify and correctly install them, thus improving work efficiency.

[0004] When painting the oil pipe coupling, pressure is applied inside the paint bucket to supply the material to the spray gun. However, it is difficult to accurately control the pressure when using it, which affects the painting effect during material supply.

[0005] Therefore, a pipe coupling painting device is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the figure, an oil pipe coupling painting device according to an embodiment of the present invention includes a painting device body 1, a control panel 11 mounted on the surface of the painting device body 1; a cabinet door 12 opened at the bottom of the painting device body 1; a gear pump 13 installed in the middle of the painting device body 1; a paint hopper 14 fixedly connected inside the painting device body 1; a nut 15 threadedly connected to the top of the paint hopper 14; the nut 15 and the gear pump 13 are connected by an extraction pipe 16; and a square plate 1 is fixedly connected to the side wall of the painting device body 1. 8; A round rod 19 is fixedly connected to the bottom of the square plate 18; A three-way valve 101 is fixedly connected to the bottom of the round rod 19; The three-way valve 101 and the gear pump 13 are connected through a delivery pipe 17; A fixing plate 102 is fixedly connected to the bottom of the round rod 19; Multiple atomizing nozzles 103 are fixedly connected to the bottom of the fixing plate 102; The atomizing nozzles 103 and the round rod 19 are connected; A placement plate 104 is fixedly connected to the outer wall of the main body 1 of the painting equipment; A support plate 105 is fixedly connected to the top of the placement plate 104; The side wall of the support plate 105 is provided with A rotating assembly 106 is included; a magnet 107 is fixedly connected to the end of the rotating assembly 106. During operation, the end of the coupling is first brought into contact with the magnet 107. Upon contact, the coupling is attracted and fixed by the magnet 107. After fixing, the gear pump 13 is started via the control panel 11 to extract the material from the paint tank 14 and then transfer it through the conveying pipe 17 to the three-way valve 101. The control panel 11 then controls the three-way valve 101 to transfer the material to one of the atomizing nozzles 103 for spraying. After spraying, the material will then contact the connector on the conveying pipe 17. After the coupling is in contact with the magnet, and the coating is completed on one side, the rotating component 106 drives the magnet 107 to adjust the coupling to the coating surface for spraying. By using the gear pump 13, the paint can be delivered by the meshing of the gears. The volume of paint discharged per revolution is relatively fixed, which can precisely control the amount of paint delivered, reduce the impact of paint on the coupling during spraying, and thus increase the coating effect. At the same time, when placing the coupling, the magnet 107 can magnetically attract the coupling to quickly fix it, which makes the placement of the coupling faster.

[0026] like Figure 4 As shown, the rotating assembly 106 includes a stepper motor 2; the stepper motor 2 and the support plate 105 are fixedly connected; the magnet 107 is rotatably connected to the support plate 105; during operation, when the spraying surface needs to be adjusted by the coupling, the stepper motor 2 can be started to drive the magnet 107 to rotate. When the magnet 107 rotates, it will drive the attracted coupling to rotate together, thereby rapidly rotating the coupling; by adding the stepper motor 2, it is more convenient to adjust the spraying surface of the coupling, and at the same time, the rotation angle of the stepper motor 2 can be controlled, so that it can adjust a specified angle each time it rotates, thereby connecting the area of ​​the previous spraying.

[0027] like Figure 4As shown, a positioning rod 3 is fixedly connected to the middle of the magnet 107; the positioning rod 3 and the magnet 107 are correspondingly arranged; during operation, when placing the coupling, the coupling can be inserted along the positioning rod 3. When the positioning rod 3 is inserted and contacts the magnet 107, it will be directly located in the middle of the magnet 107, thereby increasing the contact area between the magnet 107 and the coupling; by adding the positioning rod 3, the adjustment time when inserting the coupling can be reduced, thereby speeding up the fixing process.

[0028] like Figure 4 As shown, a friction pad 4 is fixedly attached to the surface of the positioning rod 3; the friction pad 4 and the positioning rod 3 are correspondingly arranged; during operation, when the coupling is inserted into the positioning rod 3, the friction pad 4 will be located between the coupling and the positioning rod 3, making it tightly attached to the inner wall of the coupling, and then friction will be generated through the tight attachment when the coupling rotates; by adding the friction pad 4, friction can be increased during coupling installation, and then the linkage during rotation can be increased through friction, reducing the slippage of the positioning rod 3 on the inner wall of the coupling.

[0029] like Figure 2 As shown, a stirring motor 52 is fixedly connected inside the main body 1 of the spray painting equipment; a stirring rod 5 is fixedly connected to the output end of the stirring motor 52; the stirring rod 5 is through-mounted and rotatably connected to the paint hopper 14; a spiral blade 51 is fixedly connected to the surface of the stirring rod 5; during operation, the stirring motor 52 can be started when the material is placed, causing the stirring rod 5 to rotate. When rotating, the spiral blade 51 will stir the material inside, reducing material agglomeration when the material is placed. At the same time, when the spiral blade 51 encounters agglomerates, it will also cut them off due to the force generated during rotation; by adding the spiral blade 51, the material can be mixed inside after it is placed, thereby reducing agglomeration and reducing the impact of agglomeration on the atomizing nozzle 103 during use.

[0030] like Figure 2 As shown, a heating element 6 is fixedly connected to the bottom of the paint hopper 14; multiple heating elements 6 are arranged on the paint hopper 14; during operation, when there is material inside the paint hopper 14, the heating element 6 can be activated to continuously heat up, thereby continuously transferring heat to the inside of the material, thus heating the material; by adding heating elements 6, the inside of the material can be heated, thereby reducing the clumping inside the material after it is placed, and at the same time, the fluidity between materials can be increased after heating.

[0031] Working principle: First, the end of the coupling is brought into contact with the magnet 107. Upon contact, the coupling is attracted and fixed by the magnet 107. After fixing, the gear pump 13 is started through the control panel 11 to draw the material from the paint tank 14 and then transfer it through the conveying pipe 17 to the three-way valve 101. Then, the control panel 11 controls the three-way valve 101 to transmit the material to one of the atomizing nozzles 103 for spraying. After spraying, it will contact the coupling on the conveying pipe 17. After one side of the coupling is sprayed, the rotating component 106 drives the magnet 107 to adjust the spraying surface of the coupling, thus performing spraying. When it is necessary to adjust the spraying surface of the coupling, the stepper motor 2 can be started to drive the magnet 107 to rotate. When the magnet 107 rotates, it will drive the attracted coupling to rotate together, thus rapidly rotating the coupling. When placing the coupling, it can be inserted along the positioning rod 3. When the positioning rod 3 is inserted and contacts the magnet 107, it will be located directly in the middle of the magnet 107, thereby increasing the contact area between the magnet 107 and the coupling. After the coupling is inserted into the positioning rod 3, the friction pad 4 will be located between the coupling and the positioning rod 3, making it tightly attached to the inner wall of the coupling. Then, when the coupling rotates, friction will be generated through the tight contact. When the material is placed, the stirring motor 52 can be started to drive the stirring rod 5 to rotate. When rotating, it will drive the spiral blade 51 to stir the material inside, reducing the material from clumping when the material is placed. At the same time, when the spiral blade 51 encounters clumping, it will also cut it due to the force generated during rotation. When there is material inside the paint hopper 14, the heating element 6 can be started to continuously heat up, thereby continuously transferring heat to the inside of the material and heating the material.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
