Description

Technical Field

[0001] This utility model relates to the field of pipeline testing technology, and in particular to a testing device for the thermal insulation performance of pipelines. Background Technology

[0002] In numerous practical scenarios, including pipeline manufacturing, building water supply and drainage system construction, and heating network laying, pipeline insulation performance testing is a crucial task. Whether it's heating pipelines transporting hot water or steam, or various pipelines used for building water supply and drainage, their insulation performance directly affects energy loss and performance. Precise testing using specialized equipment is necessary to ensure that heat loss during pipeline transport is within a reasonable and controllable range, preventing energy waste and problems such as condensation and freezing.

[0003] However, existing pipe insulation performance testing devices have significant shortcomings. Most devices use simple clamps to fix the pipes, but these clamps lack proper linkage design. In actual testing operations, the pipes often sway due to insecure fixing, slight vibrations from the testing equipment, and the influence of simulated media testing. Once the pipes sway, the data collected by the testing sensors will be inaccurate, failing to accurately reflect the true insulation performance of the pipes. This poses a risk to subsequent pipe quality assessment and engineering applications, and fails to meet the stringent requirements of modern pipeline engineering for testing accuracy and reliability.

[0004] Therefore, a testing device for the thermal insulation performance of pipelines is proposed to address the above-mentioned problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a testing device for the thermal insulation performance of pipelines, aiming to improve the problem that pipelines are prone to shaking when being tested in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0029] 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.

[0030] Reference Figures 1 to 3 This utility model provides an embodiment of a device for testing the thermal insulation performance of pipelines. It includes a workbench 1 as the basic support platform for the entire device, used to place the pipeline to be tested. This provides installation space and support for the drive assembly, clamping structure, cleaning assembly, etc., ensuring that all components are arranged in an orderly manner and work collaboratively. It serves as the operating carrier for testing the thermal insulation performance of pipelines. A mounting plate 2 is fixedly connected to the bottom of the workbench 1, providing a stable mounting position for the motor 3 in the drive assembly. This allows the motor 3 to be firmly connected and transmit power, ensuring stable operation of the drive assembly and serving as the initial support structure for power transmission. The top of the mounting plate 2 is fixedly connected to a drive assembly that provides power to the device, consisting of a motor 3 and an output shaft 4. The motor 3 acts as a power source, outputting power after being powered on and transmitting it to a spur gear 5 via the output shaft 4. This provides power for the movement of the clamping structure in the entire device and is the starting power component for achieving stable clamping of the pipeline.

[0031] A spur gear 5 is fixedly connected to the top of the drive assembly. The drive assembly includes a motor 3 mounted on the top of the mounting plate 2. It converts electrical energy into mechanical energy via an output shaft 4, driving the spur gear 5 to rotate, thereby moving subsequent clamping components. The output shaft 4 is the core power-generating component of the drive assembly. Its bottom is connected to the output end of the motor 3, and its top is fixed to the middle of the spur gear 5, transmitting power from the motor 3 and converting the rotation of the motor 3 into the rotation of the spur gear 5. It serves as an intermediate connecting component for power transmission. The bottom of the motor 3 is fixedly connected to the top of the mounting plate 2, and the bottom of the output shaft 4 is fixedly connected to the top of the motor 3. At the output end, the central part of the spur gear 5 is fixed to the top of the output shaft 4 and meshes with the rack plate 7. By rotating itself, it drives the rack plate 7 to slide, converting the rotational power of the drive component into the linear motion power of the rack plate 7. It is a key transmission component for realizing the linkage of the clamping structure. The central part of the transmission component is fixedly connected to the top of the output shaft 4. Fixed rods 6 are fixedly connected to the front and rear sides of the inside of the worktable 1, providing sliding guidance for the rack plate 7 and restricting the sliding direction of the rack plate 7. This ensures that the rack plate 7 can only slide along the axial direction of the fixed rods 6, thereby ensuring the stability and accuracy of the movement of the rack plate 7 and ensuring the stable operation of the clamping structure.

[0032] Both fixed rods 6 are slidably connected to rack plates 7, which are fitted onto the outside of the fixed rods 6 and mesh with the spur gears 5. Driven by the spur gears 5, they slide along the fixed rods 6, and through their own sliding motion, drive the top movable plate 8 to move. This is an intermediate transmission component that transmits power to the spur gears 5 and moves the clamping plate 12 closer to or further away. The bottom of the rack plate 7 contacts the inner wall of the bottom of the worktable 1. The spur gears 5 and rack plates 7 are meshed. The tops of both rack plates 7 are fixedly connected to the top of the rack plates 7, and the movable plates 8 follow the gears' movement. The rack 7 slides and moves, causing the sliding rod 9 to slide within the groove 13, which in turn pushes the fixed block 10 and the second moving plate 11 to move, ultimately causing the clamping plate 12 to move. It is a transition structure connecting the rack 7 and the subsequent clamping components. The top of the first moving plate 8 is fixedly connected to the sliding rod 9, which is slidably connected to the groove 13. Under the action of the first moving plate 8, it slides along the groove 13, providing guidance and support for the movement of the fixed block 10 and the second moving plate 11, and ensuring the stability of the movement of the clamping plate 12.

[0033] A fixing block 10 is fixedly connected to the other side of the sliding rod 9. The fixing block 10 is fixed to the other side of the sliding rod 9, connecting the sliding rod 9 and the second movable plate 11. It transmits the movement of the sliding rod 9 to the second movable plate 11, so that the second movable plate 11 moves synchronously with the sliding rod 9. It is a connecting component for transmitting movement. The top of the fixing block 10 is fixedly connected to the second movable plate 11, which cooperates with the first movable plate 8. The top of both are connected to the clamping plate 12, which moves with the movement of the fixing block 10, pushing the clamping plate 12 closer or further away, thereby achieving the clamping or releasing action on the pipeline. The tops of the second movable plate 11 and the first movable plate 8 are fixedly connected to the clamping plate 12, which moves closer or further away from each other under the action of the first movable plate 8 and the second movable plate 11. This is used to clamp the pipeline to be tested and to insulate the pipeline. The performance testing provides a stable fixed foundation to ensure that the pipe does not shake during the testing process. The front and rear sides of the workbench 1 are provided with grooves 13 to provide sliding space for the sliding rod 9, restrict the movement trajectory of the sliding rod 9, and enable the sliding rod 9 to slide stably, thereby ensuring the stability and accuracy of the movement of the clamping plate 12. The external sliding connection of the sliding rod 9 is slidably connected to the inside of the groove 13. The top left and right sides of the workbench 1 are provided with two sliding holes 14 to provide sliding channels for the moving plate 1 8 and the moving plate 2 11, so that the moving plate 1 8 and the moving plate 2 11 can slide along the sliding holes 14 during the clamping of the pipe, ensuring the smooth progress of the clamping action. The top of the moving plate 1 8 and the top of the moving plate 2 11 are slidably connected to the inside of the sliding holes 14.

[0034] Reference Figure 3 and Figure 4 A support frame 15 is fixedly connected to the top of the workbench 1, providing installation support for cleaning components such as motor 17, threaded rod 18, moving plate 19, and guide rod 23, thus constructing the installation framework for the cleaning components and enabling them to operate stably. A mounting plate 16 is fixedly connected to the top rear side of the support frame 15, providing a stable installation position for motor 17 and ensuring its stable operation during cleaning. This plate 16 is the supporting component for the power source of the cleaning components. Motor 17 is fixedly connected to the top of mounting plate 16 and installed thereon. Its output end drives the threaded rod 18 to rotate, providing power for the movement of the cleaning components.

[0035] Motor 2 17 drives movable plate 3 19 to move along threaded rod 18 and guide rod 23, and is the power generating component of the cleaning assembly. The output end of motor 2 17 is fixedly connected to threaded rod 18 and externally connected to movable plate 3 19. Through its own rotation, it drives movable plate 3 19 to slide along guide rod 23, converting the rotational power of motor 2 17 into the linear motion power of movable plate 3 19. It is the transmission component for the movement of the cleaning assembly. The external thread of threaded rod 18 is connected to movable plate 3 19 and threaded rod 18. The middle right side is slidably connected to guide rod 23. Driven by threaded rod 18, it moves along guide rod 23, providing a moving carrier for electric push rod 20, connecting plate 21 and brush 22 in the cleaning assembly, so that the cleaning assembly can clean different parts of the pipe. The bottom of movable plate 3 19 is fixedly connected to a cleaning assembly for cleaning the outside of the pipe. The cleaning assembly consists of electric push rod 20, connecting plate 21 and brush 22, and is used to clean dust and impurities on the surface of the pipe.

[0036] The electric push rod 20 adjusts the height of the connecting plate 21, allowing the brush 22 to contact the pipe. Moving with the movable plate 3 19, it cleans the pipe surface, providing a clean testing surface for subsequent insulation performance testing. The cleaning assembly includes an electric push rod 20 fixed to the bottom of the movable plate 3 19, with its output end connected to the connecting plate 21. The height of the connecting plate 21 is telescopically adjustable, allowing the brush 22 at the bottom of the connecting plate 21 to adapt to pipes of different heights, ensuring full contact between the brush 22 and the pipe surface. This component in the cleaning assembly is responsible for adjusting the height of the brush 22 and connecting... Plate 21 is fixed to the output end of electric push rod 20, and multiple brushes 22 are set at the bottom. Under the adjustment of electric push rod 20, they contact the surface of the pipe. As the moving plate 3 19 moves, the brushes 22 clean the surface of the pipe. It is the mounting carrier of brushes 22 and the execution component of cleaning action. The bottom of electric push rod 20 is fixedly connected to the bottom of moving plate 3 19, and the top of connecting plate 21 is fixedly connected to the output end of electric push rod 20. Multiple brushes 22 are set at the bottom of connecting plate 21 and contact the surface of the pipe.

[0037] Driven by the connecting plate 21, the moving plate 19 moves with the moving plate 3. Through friction with the pipe surface, it removes dust, impurities, etc. from the pipe surface, providing a clean testing environment for subsequent pipe insulation performance testing and improving the accuracy of test data. A guide rod 23 is fixedly connected to the top right side of the support frame 15 and is slidably connected to the middle right side of the moving plate 3. This provides guidance for the movement of the moving plate 3.19 and restricts the direction of movement of the moving plate 3.19, allowing the moving plate 3.19 to slide stably along the threaded rod 18 and the guide rod 23, ensuring the stability of the cleaning component's movement. The middle right side of the moving plate 3.19 is slidably connected to the outside of the guide rod 23. Support legs are provided at the four corners of the bottom of the workbench 1 to provide support for the entire testing device.

[0038] Working principle: First, the pipe to be tested is placed on the workbench 1. Then, the drive assembly is started, and the motor 3 in the drive assembly runs, driving the output shaft 4 to rotate. The sprocket 5 at the top of the output shaft 4 rotates accordingly. Since the sprocket 5 and the rack plate 7 are meshed, the rotation of the sprocket 5 will cause the rack plates 7 on both sides to slide outside the fixed rod 6. When the rack plate 7 slides, the top moving plate 8 moves synchronously. The moving plate 8 drives the sliding rod 9 to slide in the groove 13. The fixed block 10 on the other side of the sliding rod 9 and the moving plate 11 on the top of the fixed block 10 also move accordingly. Finally, the clamping plate 12 on the top of the moving plate 8 and the moving plate 11 moves closer to each other, clamping and fixing the pipe.

[0039] Then, motor 17 on the top support frame 15 of workbench 1 can be started. The output end of motor 17 drives the threaded rod 18 to rotate. The movable plate 19, which is externally threaded to the threaded rod 18, will move along the direction of the threaded rod 18 and the guide rod 23 because its right side is slidably connected to the guide rod 23. The cleaning component at the bottom of the movable plate 19 moves accordingly. The electric push rod 20 in the cleaning component can adjust the position of the connecting plate 21 according to the pipe height, so that the multiple brushes 22 at the bottom of the connecting plate 21 contact the pipe surface. During the movement of the movable plate 19, the brushes 22 clean the outside of the pipe, removing dust, impurities, etc., to ensure the accuracy of subsequent insulation performance testing.

[0040] 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.
