Description

Technical Field

[0001] This application relates to the field of oil and gas pipeline technology, specifically an anti-corrosion coating spraying device for oil and gas pipelines. Background Technology

[0002] Oil and gas pipelines are trunk pipelines used to transport oil or natural gas from their development areas (oil and gas fields) to oil and gas processing enterprises, railways, river and sea loading points and transmission pump (distribution) stations, or to transport oil and natural gas from pumping stations, compressor stations, and gas distribution stations to oil depots and gas storage (tanks) in urban consumption areas. Before use, oil and gas pipelines need to be coated with an anti-corrosion coating to improve their service life.

[0003] Existing anti-corrosion coating equipment for oil and gas pipelines is mostly completed by automatic spraying equipment, but it still needs to be done manually. Moreover, pipeline spraying can only be done on one side, resulting in low spraying efficiency and inconvenience.

[0004] Therefore, this application provides an anti-corrosion coating spraying device for oil and gas transmission pipelines to solve the above problems. Utility Model Content

[0005] This application provides an anti-corrosion coating spraying device for oil and gas pipelines, which aims to solve the problems mentioned in the background art that the existing anti-corrosion coating spraying equipment for oil and gas pipelines is mostly completed by automatic spraying equipment, but still needs to be completed manually, and the pipeline spraying can only be carried out on one side, resulting in low spraying efficiency and inconvenience of use.

[0006] To achieve the above objectives, this application provides the following technical solution: an anti-corrosion coating spraying device for oil and gas pipelines, including a fixed base, a spraying device on one side of the fixed base, a connecting hose on the top of the spraying device, a spraying head at one end of the connecting hose, and a spraying mechanism on the top of the fixed base.

[0007] Preferably, to address the issues that existing oil and gas pipeline anti-corrosion coating equipment mostly relies on automated spraying equipment but still requires manual operation, and that pipeline spraying can only be performed on one side, resulting in low efficiency and inconvenience, the spraying mechanism includes an operating frame fixedly connected to the top of a fixed base. A dual-axis motor is installed inside one end of the operating frame. The output end of the dual-axis motor extends into the operating frame and is fixedly connected to a reciprocating screw. A moving block is installed outside the reciprocating screw. Both ends of the moving block extend into the operating frame and are fixed to operating slot blocks. Two sets of sliding blocks are installed inside each of the two sets of operating slot blocks. A fixing clamp is fixedly connected to one end of each sliding block. The clamping blocks are compatible with the spray head. The spray head is placed between two sets of fixed clamping blocks, and the contact between the spray head and the fixed clamping blocks causes the fixed clamping blocks to be stressed, causing the sliding block to slide outside the guide rod. The sliding block compresses the spring on its side, and the fixed clamping blocks are subjected to the spring's rebound force. The two sets of fixed clamping blocks can fix the spray head in place. A dual-axis motor drives a reciprocating screw to rotate inside the operating frame. The reciprocating screw is threadedly connected to a moving block, allowing the moving block to slide outside the limit rod. The moving block drives the operating slot block to move, thus allowing the spray head to move. This facilitates spraying oil and gas pipelines and makes it easy to install and fix the spray head. The operation is simple, quick, and convenient.

[0008] Preferably, to address the issue of convenient movement of the movable block, the reciprocating screw is rotatably connected to the operating frame, the reciprocating screw is threadedly connected to the movable block, a limit rod is fixedly connected inside the operating frame, the movable block is disposed outside the limit rod, and the movable block is slidably connected to the limit rod. The reciprocating screw is threadedly connected to the movable block, allowing the movable block to slide outside the limit rod under force, thereby enabling the movable block to move and facilitating operation.

[0009] Preferably, in order to solve the problem of the stability of the sliding block movement, a guide rod is fixedly connected inside the operating groove block, the sliding block is disposed outside the guide rod, and the sliding block is slidably connected to the guide rod.

[0010] Preferably, in order to solve the problem of convenient operation of the sliding block, a spring is sleeved on the outside of the guide rod. The spring is fixedly connected between the side of the sliding block and the inside of the operating groove block. When the sliding block compresses the spring on the side, the sliding block can easily return to its original shape through the spring, making it convenient to use.

[0011] Preferably, to solve the problem of fixing the oil and gas pipeline, a first rotating wheel is fixedly connected to the output end of the dual-axis motor. A transmission belt is fitted around the outside of the first rotating wheel, one end of which is fitted around the outside of a second rotating wheel. One end of the second rotating wheel extends to the outside of the fixed base and is fixedly connected to a mounting block. A hydraulic rod is fixedly connected to the side of the mounting block, and a bidirectional electric actuator is fixedly connected to the output end of the hydraulic rod. A friction block is fixedly connected to the output end of the bidirectional electric actuator. The dual-axis motor drives the first rotating wheel to rotate, and the transmission belt on the outside of the first rotating wheel drives the second rotating wheel to rotate synchronously. The second rotating wheel drives the mounting block to rotate. Activating the hydraulic rod on the side of the mounting block allows the hydraulic rod to push the bidirectional electric actuator to move. The bidirectional electric actuator pushes the friction blocks on both sides to move. The two sets of friction blocks support the inside of the pipeline, thereby driving the oil and gas pipeline to rotate. This supports the oil and gas pipeline, allowing it to rotate, facilitating rapid spraying operations and improving spraying efficiency.

[0012] Preferably, to address the issue of ease of use, the two sets of friction blocks are arranged symmetrically inside the oil and gas transmission pipeline. This symmetrical arrangement of the friction blocks facilitates pipeline support and makes the pipeline convenient to use.

[0013] This spraying mechanism places the spray head between two sets of fixed clamping blocks. The spray head contacts the fixed clamping blocks, causing the fixed clamping blocks to slide outside the guide rod under force. The sliding block compresses the spring on its side, and the fixed clamping blocks are subjected to the spring's rebound force. The two sets of fixed clamping blocks can fix the spray head. A dual-axis motor drives a reciprocating screw to rotate inside the operating frame. The reciprocating screw is threadedly connected to a moving block, allowing the moving block to slide outside the limit rod under force. The moving block drives the operating slot block to move, thereby moving the spray head. This allows for convenient spraying of oil and gas pipelines and easy installation and fixing of the spray head. The operation is simple, quick, and convenient.

[0014] This spraying mechanism uses a dual-axis motor to drive a first rotating wheel, which in turn drives a second rotating wheel to rotate synchronously via a transmission belt on the outside of the first rotating wheel. The second rotating wheel then drives a mounting block to rotate. Activating a hydraulic rod on the side of the mounting block causes the hydraulic rod to push a bidirectional electric actuator to move. The bidirectional electric actuator then pushes friction blocks on both sides to move. These two sets of friction blocks support the inside of the pipeline, thereby driving the oil and gas transport pipeline to rotate. This facilitates rapid spraying of the pipeline and improves spraying efficiency. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides an anti-corrosion coating spraying device for oil and gas transmission pipelines, such as... Figure 1-4 As shown, the anti-corrosion coating spraying device for oil and gas pipelines includes a fixed base 1, a spraying device 2 is provided on one side of the fixed base 1, a connecting hose 3 is provided on the top of the spraying device 2, a spraying head 4 is provided at one end of the connecting hose 3, and a spraying mechanism 5 is provided on the top of the fixed base 1.

[0024] The spraying mechanism 5 allows for convenient spraying of oil and gas pipelines and easy installation and fixing of the spray head 4. It is simple, quick and easy to use, and can support the oil and gas pipelines, allowing the pipelines to rotate and facilitating rapid spraying operations, thus improving spraying efficiency.

[0025] Specifically, the spraying mechanism 5 includes an operating frame 51 fixedly connected to the top of the fixed base 1. A dual-axis motor 52 is installed inside one end of the operating frame 51. The output end of the dual-axis motor 52 extends into the operating frame 51 and is fixedly connected to a reciprocating screw 53. A moving block 54 is installed outside the reciprocating screw 53. Both ends of the moving block 54 extend into the outside of the operating frame 51 and are fixed to operating slot blocks 56. Two sets of sliding blocks 58 are installed inside each of the two sets of operating slot blocks 56. A fixed clamping block 59 is fixedly connected to one end of the sliding block 58. The fixed clamping block 59 is adapted to the spraying head 4.

[0026] In use, the spray head 4 is placed between two sets of fixed clamps 59. The spray head 4 contacts the fixed clamps 59, causing the fixed clamps 59 to be forced to slide the sliding block 58 outside the guide rod 57. The sliding block 58 compresses the spring 60 on its side, and the fixed clamps 59 are subjected to the rebound force of the spring 60. The spray head 4 can be fixed by the two sets of fixed clamps 59. The reciprocating screw 53 is driven by the dual-axis motor 52 to rotate inside the operating frame 51. The reciprocating screw 53 is threadedly connected to the moving block 54, which allows the moving block 54 to slide outside the limit rod 55. The moving block 54 drives the operating slot block 56 to move, thereby allowing the spray head 4 to move. This facilitates spraying oil and gas pipelines and makes it easy to install and fix the spray head 4. The operation is simple, quick, and convenient.

[0027] Furthermore, the reciprocating screw 53 is rotatably connected to the operating frame 51, and the reciprocating screw 53 is threadedly connected to the moving block 54. The operating frame 51 is internally fixedly connected to a limit rod 55, and the moving block 54 is located outside the limit rod 55 and is slidably connected to the limit rod 55. The reciprocating screw 53 is threadedly connected to the moving block 54, which allows the moving block 54 to slide outside the limit rod 55 under force, thereby enabling the moving block 54 to move and facilitating operation.

[0028] Furthermore, a guide rod 57 is fixedly connected inside the operating slot block 56, and a sliding block 58 is disposed outside the guide rod 57 and slidably connected to the guide rod 57. The sliding block 58 slides outside the guide rod 57. The stability of the movement of the sliding block 58 can be improved by the guide rod 57.

[0029] Specifically, a spring 60 is sleeved on the outside of the guide rod 57. The spring 60 is fixedly connected between the side of the sliding block 58 and the inside of the operating groove block 56. When the sliding block 58 compresses the spring 60 on its side, the sliding block 58 can easily return to its original shape, making it convenient to use.

[0030] Example 2

[0031] Unlike Embodiment 1, in order to solve the problem of fixing the oil and gas transmission pipeline, a first rotating wheel 61 is fixedly connected to the output end of the dual-shaft motor 52. A transmission belt 62 is sleeved on the outside of the first rotating wheel 61. One end of the transmission belt 62 is sleeved on the outside of the second rotating wheel 63. One end of the second rotating wheel 63 extends to the outside of the fixed base 1 and is fixedly connected to the mounting block 64. A hydraulic rod 65 is fixedly connected to the side of the mounting block 64. A bidirectional electric actuator 66 is fixedly connected to the output end of the hydraulic rod 65. A friction block 67 is fixedly connected to the output end of the bidirectional electric actuator 66.

[0032] In use, the dual-axis motor 52 drives the first rotating wheel 61 to rotate, and the transmission belt 62 set on the outside of the first rotating wheel 61 drives the second rotating wheel 63 to rotate synchronously. The second rotating wheel 63 drives the mounting block 64 to rotate. Activating the hydraulic rod 65 set on the side of the mounting block 64 allows the hydraulic rod 65 to push the bidirectional electric actuator 66 to move. The bidirectional electric actuator 66 pushes the friction blocks 67 set on both sides to move. The two sets of friction blocks 67 support the inside of the pipeline, thereby driving the oil and gas transmission pipeline to rotate. This supports the oil and gas transmission pipeline and allows it to rotate, facilitating quick and easy spraying operations on the pipeline and improving spraying efficiency.

[0033] Specifically, the two sets of friction blocks 67 are symmetrically arranged inside the oil and gas transmission pipeline. The symmetrical arrangement of the friction blocks 67 can easily support the pipeline and is convenient to use.

[0034] It should be noted that the spraying equipment 2, the dual-axis motor 52, the hydraulic rod 65, and the bidirectional electric actuator 66 are existing equipment. Their working principle, size, and model are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0035] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
