Description

Technical Field

[0001] This utility model relates to the field of thermal insulation pipe production technology, and in particular to a positioning device for the production of spray-coated and wound thermal insulation pipes. Background Technology

[0002] In the field of industrial pipeline insulation engineering, spray-coated spiral wound insulation pipes are widely used in many industries such as petroleum, chemical, and heating due to their excellent thermal insulation performance and protective effect. To ensure the production quality of insulation pipes, the positioning device used in the production of spray-coated spiral wound insulation pipes plays a crucial role, and its performance directly affects the production efficiency and finished product accuracy of the insulation pipes.

[0003] Currently, most common positioning devices for insulated pipe production adopt a fixed-station structure. By fixing the pipe in a specific position, spraying equipment and winding machinery are used to spray and wrap the pipe with insulation material. These devices typically rely on fixed supports and clamps to restrict pipe movement. Operators must manually move the pipe to the designated station, and after the insulation material spraying and wrapping are completed, the finished product is removed. The entire production process depends on a fixed production flow and equipment layout.

[0004] However, traditional positioning devices, because the pipes are produced in fixed positions, make it difficult to enable mobile operations, resulting in a long spraying and wrapping process. On the one hand, each pipe requires a series of operations such as loading, unloading, and positioning, making the process cumbersome; on the other hand, the pipe position cannot be flexibly adjusted during the spraying and wrapping process, making it difficult to ensure uniform coverage of the insulation material. This makes it difficult to improve the production accuracy of the insulation pipes and results in low production efficiency, making it difficult to meet the needs of large-scale production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a positioning device for the production of spray-coated and wound insulation pipes, which aims to improve the traditional positioning device. Since the pipe is completed in a fixed position for insulation pipe production, it is difficult to achieve mobile operation, resulting in a long time consumption in the spray-coating and winding process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for the production of spray-coated and wound insulation pipes, including a workbench, a sliding plate slidably connected inside the workbench, two supports slidably connected inside the sliding plate, an electric slide rail fixedly connected inside the workbench, the output end of the electric slide rail fixedly connected to the sliding plate, and a driving component provided on the outer wall of the sliding plate;

[0007] The drive assembly includes a motor, the outer wall of which is fixedly connected to the outer wall of the sliding plate. A turntable is fixedly connected to the output end of the motor. A turntable is positioned above the turntable. A belt drive mechanism is provided on the outer wall of the turntable. The belt drive mechanism consists of a belt and two matching drive wheels. The two drive wheels are fixedly connected to the turntable and the turntable, respectively. The turntable is fixedly connected to one end of the belt drive mechanism. A connecting rod is slidably connected inside both the turntable and the turntable. Guide blocks are slidably connected to the outer walls of the four connecting rods. A clamping plate is fixedly connected to the top of the support. A guide assembly is provided inside the worktable.

[0008] Furthermore, a triangular plate is slidably connected inside the worktable, and a cylinder is fixedly connected inside the worktable. The output end of the cylinder is connected to the outer wall of the triangular plate. A slider is slidably connected to the outer wall of the triangular plate. A rotating rod is rotatably connected to one end of the slider. The outer wall of the rotating rod is rotatably connected to the inside of the worktable. A connecting rod is rotatably connected to one end of the rotating rod. A clamping assembly is provided at one end of the connecting rod.

[0009] Furthermore, the clamping assembly includes a clamp, one end of which is fixedly connected to one end of a connecting rod, one end of which is rotatably connected to a rotating shaft, a rubber pad is fixedly connected to the inner wall of the clamp, and a rotating assembly is provided on the outer wall of the clamp.

[0010] Furthermore, the rotating assembly includes a second motor and multiple drive wheels. The outer wall of the second motor is fixedly connected to the outer wall of the clamp, and the output end of the second motor is fixedly connected to one of the drive wheels.

[0011] Furthermore, the triangular plate is triangular in shape and has a groove inside for the bottom of the slider to slide.

[0012] Furthermore, both ends of the rotating shaft are fixedly connected to the inside of the worktable.

[0013] Furthermore, both turntable one and turntable two have worm-shaped slides inside for the connecting rods to slide, and one end of each of the four connecting rods is fixedly connected to the outer wall of the bracket.

[0014] Furthermore, the outer wall of the slider is slidably connected to the inside of the worktable, and the outer wall of the guide block is fixedly connected to the inside of the sliding plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the clamping plate is first moved on the outer wall of the pipe by an electric slide rail. Then, the clamping plate is driven by a motor, a turntable, a belt drive mechanism, a turntable, a connecting rod, a guide block, and a bracket to produce pressure insulation pipes for the pipe. This solves the problem of the difficulty in producing insulation pipes by moving the pipe, and achieves the production of movable insulation pipes. This allows the insulation pipes to be sprayed and wrapped in a shorter time, saving production time and improving the production accuracy of the insulation pipes.

[0017] 2. In this utility model, the cylinder first drives the triangular plate to move, and at the same time, the slider, rotating rod, connecting rod and rotating shaft drive the clamp and rubber pad to clamp the two sides of the pipe, thereby fixing the pipe and preventing the pipe from shifting during the production of the insulation pipe. Finally, the motor is started and the drive wheel can effectively drive the insulation pipe to rotate and adjust, thereby improving the production accuracy of the insulation pipe and ensuring the safety of the insulation pipe production.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3 An embodiment of this utility model provides a positioning device for the production of spray-coated and wound insulation pipes, including a workbench 1, a sliding plate 3 slidably connected inside the workbench 1, two supports 10 slidably connected inside the sliding plate 3, an electric slide rail 2 fixedly connected inside the workbench 1, the output end of the electric slide rail 2 fixedly connected to the sliding plate 3, and a drive assembly provided on the outer wall of the sliding plate 3.

[0026] The drive assembly includes a motor 4, the outer wall of which is fixedly connected to the outer wall of the sliding plate 3. The output end of the motor 4 is fixedly connected to a turntable 5. A turntable 7 is arranged above the turntable 5. A belt drive mechanism 6 is arranged on the outer wall of the turntable 5. The belt drive mechanism 6 consists of a belt and two matching drive wheels. The two drive wheels are fixedly connected to the turntable 5 and the turntable 7 respectively. One end of the belt drive mechanism 6 is fixedly connected to the turntable 7. The interiors of the turntable 5 and the turntable 7 are slidably connected to connecting rods 8. The outer walls of the four connecting rods 8 are slidably connected to guide blocks 9. The top of the bracket 10 is fixedly connected to a clamping plate 11. The interior of the worktable 1 is provided with a guide assembly.

[0027] Specifically, firstly, the electric slide rail 2 drives the sliding plate 3 to move inside the worktable 1, enabling comprehensive internal and external wall spraying of the pipe without damaging it. The speed and direction of the sliding plate 3 can be precisely controlled, ensuring the accuracy of the spraying process. Next, the motor 4 drives the turntable 5 to rotate. The arc-shaped groove on the turntable 5 cooperates with one end of the connecting rod 8, allowing the connecting rod 8 to slide inside the turntable 5. This allows the connecting rod 8 to drive the supports 10 on both sides to move, thus achieving precise control of the position of the pipe supports 10. On this basis, the belt drive mechanism 6 drives the turntable 7 on the other side to rotate synchronously with the turntable 5, ensuring the synchronicity of the two turntables. This allows the other two connecting rods 8 to move simultaneously, guiding the movement of the supports 10. Finally, the guide block 9 guides the movement of the connecting rod 8, preventing the connecting rod 8 from detaching from the control of the turntable 5 and the turntable 7 during the spraying process. This ensures the stability and safety of the entire spraying process and avoids potential accidents caused by the uncontrolled connecting rod 8.

[0028] Reference Figure 1 , Figure 3 and Figure 4 A triangular plate 13 is slidably connected inside the workbench 1. A cylinder 12 is fixedly connected inside the workbench 1. The output end of the cylinder 12 is connected to the outer wall of the triangular plate 13. A slider 14 is slidably connected to the outer wall of the triangular plate 13. A rotating rod 15 is rotatably connected to one end of the slider 14. The outer wall of the rotating rod 15 is rotatably connected inside the workbench 1. A connecting rod 16 is rotatably connected to one end of the rotating rod 15. A clamping assembly, including a clamp 18, is provided at one end of the connecting rod 16. A rotating shaft 17 is rotatably connected to one end of the clamp 18. A rubber pad 19 is fixedly connected to the inner wall of the clamp 18. The outer wall of the fixture 18 is provided with a rotating assembly, which includes a second motor 20 and multiple drive wheels 21. The outer wall of the second motor 20 is fixedly connected to the outer wall of the fixture 18. The output end of the second motor 20 is fixedly connected to one of the drive wheels 21. The triangular plate 13 is triangular in shape and has a groove inside for the bottom of the slider 14 to slide. Both ends of the rotating shaft 17 are fixedly connected to the inside of the worktable 1. The inside of the turntable 5 and the second turntable 7 are provided with worm-shaped slides for the connecting rods 8 to slide. One end of each of the four connecting rods 8 is fixedly connected to the outer wall of the bracket 10. The outer wall of the slider 14 is slidably connected to the inside of the worktable 1. The outer wall of the guide block 9 is fixedly connected to the inside of the sliding plate 3.

[0029] Specifically, firstly, the output end of cylinder 12 drives the triangular plate 13 to move inside the worktable 1, thereby enabling the slider 14 to slide on the inclined surface of the triangular plate 13, allowing the slider 14 to move up and down. The movement of the slider 14 is not the end point, but the starting point of another process. The movement of the slider 14 drives one end of the rotating rod 15 to rotate. At the same time, the other end of the rotating rod 15 drives the connecting rod 16 to rotate around the rotating shaft 17. The rotation of the connecting rod 16 ultimately causes the clamp 18 to rotate. The rotation of the clamp 18 then drives the rubber pad 19 to clamp the pipe, achieving pipe fixation. Finally, the drive motor 20 drives the drive wheel 21 to rotate. With the assistance of the other three drive wheels 21, the insulation pipe can be rotated to achieve adjustment.

[0030] Working principle: When the positioning device for spray-coated and wound insulation pipe production is needed, the electric slide rail 2 first drives the sliding plate 3 to move, thereby causing the two clamping plates 11 to slide on the outer wall of the pipe. Then, the motor 4 drives the turntable 5 to rotate, causing one end of the connecting rod 8 to slide in the pre-set arc-shaped groove inside the turntable 5, thereby driving the two supports 10 on both sides to move. During this process, the belt transmission mechanism 6 drives the other turntable 7 to rotate synchronously with the turntable 5, thereby driving the other two connecting rods 8 to move, thus guiding the movement of the supports 10. Finally, the guide block 9 guides the movement of the connecting rods 8. The moving guide prevents the connecting rod 8 from disengaging from the control of the turntable 5 and the turntable 7, thereby achieving the effect of moving and spraying the insulation pipe. Then, the cylinder 12 drives the triangular plate 13 to move inside the worktable 1, thereby driving the slider 14 to slide on the inclined surface of the triangular plate 13, and thus causing the slider 14 to move up and down. Finally, the movement of the slider 14 drives one end of the rotating rod 15 to rotate, and at the same time, the other end of the rotating rod 15 drives the connecting rod 16 to rotate around the rotating shaft 17, thereby driving the clamp 18 to rotate, and then the clamp 18 drives the rubber pad 19 to clamp the pipe, achieving the effect of fixing.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
