Description

Technical Field

[0001] This invention relates to the field of chemical pipeline support technology, specifically a planar universal rolling ultra-low friction support device. Background Technology

[0002] In the petrochemical, power, and other fields, pipe supports are used to support pipelines and equipment. Many high-temperature pipelines used to transport gases or liquids experience significant internal temperature variations. According to the principle of thermal expansion and contraction, the pipeline deforms with temperature changes, generating stress. Since the pipeline is not a straight pipe, the direction of displacement caused by stress is uncertain; it could be axial or radial displacement. Current methods use pipe supports with friction pairs to reduce the uncertain displacement stress on high-temperature pipelines. The friction pair reduces the frictional force generated by pipeline movement by sliding between a PTFE plate and a mirror-finished stainless steel plate. The disadvantage of this type of pipe support is that the friction between the PTFE plate and the mirror-finished stainless steel plate is sliding friction, resulting in a high coefficient of friction, and the frictional force increases with the load.

[0003] Some chemical pipeline support devices reduce friction by setting ball bearing seats. However, the balls inside the ball bearing seats will still rub against the inner wall of the housing. This cannot completely replace sliding friction with rolling friction, which is inconvenient for users.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-5 In this embodiment of the invention, the planar universal rolling ultra-low friction support device includes a first mounting frame 1 and a rolling support mechanism. A second mounting frame 4 is horizontally arranged at the top center of the first mounting frame 1. A first support block 3 is installed at the upper end of the second mounting frame 4. A support bracket 2 for supporting chemical pipelines is installed at the upper end of the first support block 3. A plurality of springs 5 ​​for buffering the second mounting frame 4 are installed on the side wall of the second mounting frame 4. The end of the spring 5 away from the second mounting frame 4 is installed on the upper end of the inner wall of the first mounting frame 1.

[0029] The rolling support mechanism is located at the lower end of the second mounting frame 4 and is used to provide rolling support for the second mounting frame 4, thereby reducing the friction when the second mounting frame 4 moves.

[0030] The rolling support mechanism includes several support frames 7, which are horizontally arranged below the second mounting frame 4. A support column 21 is vertically installed at the bottom center of the support frame 7. A support platform 9 is horizontally installed at the upper end of the support column 21. A ball 8 is rolled on the upper end of the support platform 9. The upper end of the ball 8 is close to the lower end of the second mounting frame 4. A second support block 24 for supporting the support platform 9 is installed on the upper side wall of the support column 21. The upper end of the second support block 24 is installed at the lower end of the support platform 9. A detection component is provided inside the support frame 7 to detect whether the ball 8 is located on the upper end of the support platform 9 near the inner wall of the support frame 7.

[0031] Compared with traditional ball bearing seats, the ball bearing 8 is not restricted, allowing it to roll simultaneously on the upper end of the support platform 9 and the lower end of the second mounting frame 4. There is no sliding friction on the side wall of the ball bearing 8, which effectively reduces the friction when the second mounting frame 4 moves, making it easier for users to use.

[0032] The detection assembly includes a movable ring 10, which is disposed between the support platform 9 and the support frame 7. The side wall of the movable ring 10 is slidably connected to the inner wall of the support frame 7, and the inner wall of the movable ring 10 is slidably connected to the side wall of the support platform 9. The upper end of the movable ring 10 near the support platform 9 is provided with an inclined surface to facilitate the ball 8 to squeeze the movable ring 10. A pressure sensor 23 is installed at the bottom of the support frame 7, and the lower end of the movable ring 10 is in close contact with the detection end of the pressure sensor 23. The lower end of the support frame 7 is provided with a reset assembly for moving the support frame 7 to reset the ball 8 to the center position of the upper end of the support platform 9.

[0033] The reset assembly includes a third magnet 22, which is mounted at the center of the upper end of the support platform 9. A first magnet 11 is mounted on the inclined surface of the moving ring 10. Several mounting holes 25 are provided on the side wall of the ball 8. A second magnet 20 is installed inside the mounting holes 25. The polarity of the end of the second magnet 20 away from the center of the ball 8 is different from the polarity of the upper end of the third magnet 22. The polarity of the end of the second magnet 20 away from the center of the ball 8 is the same as the polarity of the end of the first magnet 11 away from the moving ring 10. A thread for moving the support frame 7 away from the second mounting frame 4 is vertically mounted on the lower end of the support frame 7. The threaded column 18 has an internally threaded rotating cylinder 12 rotatably connected to its side wall via a thread. The lower end of the internally threaded rotating cylinder 12 is rotatably connected to a rotating seat 13. The rotating seat 13 is installed at the bottom of the first mounting frame 1. Several balls 19 are installed on the inner wall of the rotating seat 13 to facilitate the rotation of the internally threaded rotating cylinder 12. A limit rod 26 is vertically installed at the lower end of the side wall of the support frame 7. A limit sleeve 27 is slidably sleeved on the side wall of the limit rod 26. The lower end of the limit sleeve 27 is installed at the bottom of the first mounting frame 1. A drive assembly for driving the entire row of internally threaded rotating cylinders 12 is installed at the bottom of the first mounting frame 1.

[0034] The drive assembly includes a motor 15, which is mounted on the bottom of a first mounting frame 1 at one end of a row of internally threaded rotating cylinders 12. A first sprocket 16 is mounted on the output end of the motor 15. A second sprocket 17 is mounted on the side wall of the internally threaded rotating cylinder 12. A chain 14 is fitted on the side walls of the second sprocket 17 and the first sprocket 16 in the same row to drive the second sprocket 17 to rotate. A controller 6 is mounted on the side wall of the first mounting frame 1 to receive signals from the pressure sensor 23 and control the motor 15.

[0035] Compared with existing technologies, by utilizing the principle of like poles repelling and unlike poles attracting, the rolling ball 8 located at the edge of the support platform 9 can be reset and moved to the center of the upper end of the support platform 9, ensuring the rolling efficiency of the rolling ball 8. At the same time, by controlling the single row of support frames 7, when the rolling ball 8 is reset, only the row of support frames 7 that needs to be reset can be controlled, avoiding the second mounting frame 4 from lacking support, which would cause the second mounting frame 4 and the chemical pipeline to move, thus protecting the chemical pipeline. It also facilitates the maintenance of the rolling ball 8 and the support frame 7 by the staff and is convenient for the user.

[0036] The working principle of the planar universal rolling ultra-low friction support device is as follows: When the chemical pipeline is displaced due to temperature changes, the chemical pipeline will drive the support bracket 2 to move, the support bracket 2 will drive the first support block 3 to move, the first support block 3 will drive the second mounting frame 4 to move, and the second mounting frame 4 will drive the ball 8 to roll. The ball 8 rolls along the upper end of the support platform 9 to achieve stable support for the chemical pipeline.

[0037] When the ball 8 rolls and presses against the inclined surface of the moving ring 10, the moving ring 10 is compressed and moves downward. The moving ring 10 presses against the pressure sensor 23, and the pressure sensor 23 sends a signal to the controller 6. The controller 6 controls the corresponding motor 15 to start. The output end of the motor 15 drives the first sprocket 16 to rotate. The first sprocket 16 drives the chain 14 to rotate. The chain 14 drives the second sprocket 17 to rotate. The second sprocket 17 drives the internal thread rotating cylinder 12 to rotate. Under the action of the thread, the internal thread rotating cylinder 12 drives the threaded column 18 to move downward. The threaded column 18 drives the support frame 7 to move downward, thereby moving the ball 8 away from the second mounting frame 4.

[0038] Simultaneously, due to the repulsion of like poles and the attraction of unlike poles, the first magnet 11 and the second magnet 20 repel each other, while the third magnet 22 and the second magnet 20 attract each other. This causes the rolling ball 8 to move to the center position at the upper end of the support platform 9. After a period of time, the motor 15 is started. The output end of the motor 15 drives the first sprocket 16 to rotate. The first sprocket 16 drives the chain 14 to rotate. The chain 14 drives the second sprocket 17 to rotate. The second sprocket 17 drives the internal thread rotating cylinder 12 to rotate. Under the action of the thread, the internal thread rotating cylinder 12 drives the threaded column 18 to move upward. The threaded column 18 drives the support frame 7 to move upward, thereby causing the rolling ball 8 to re-adhere tightly to the lower end of the second mounting frame 4, facilitating the re-movement of the second mounting frame 4.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
