Description

Technical Field

[0001] This application relates to the field of pipeline support structure technology, specifically a vacuum pipeline elbow support structure. Background Technology

[0002] Vacuum technology is being used more and more widely. However, in practical applications, especially in large vacuum equipment, ensuring the safe and stable operation of complex-shaped pipes (such as bends) has become a problem. Although existing vacuum pipe support structures can meet the strength requirements to a certain extent, they still have limitations in dealing with deformation and vibration under extreme conditions.

[0003] Currently, the common vacuum pipe support methods on the market mainly include two forms: rigid fixed brackets and support springs. Although rigid fixed brackets have good stability, they are sensitive to external impacts and are prone to changes in internal pipe pressure or even rupture. Support springs have good shock absorption performance, but due to their material limitations, their service life is limited in high or low temperature environments. In addition, these two traditional support methods are difficult to adapt to pipes with different diameters and bending angles, and have poor versatility and flexibility. In order to solve the above problems, a vacuum pipe elbow support structure is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a vacuum pipe elbow support structure, which can improve the adaptability and reliability of vacuum pipe support structures and reduce the risk of pipe damage caused by external vibrations.

[0005] To achieve the above objectives, this application provides the following technical solution: a vacuum pipe elbow support structure, comprising a base, a sleeve, and a height adjustment mechanism disposed inside the sleeve. The height adjustment mechanism includes a support column sleeved on the inner wall of the sleeve and a threaded rod rotatably sleeved on the bottom wall of the inner wall of the sleeve. The outer surface of the threaded rod is threadedly connected to the inner wall of the support column. An angle adjustment mechanism is provided at the top of the support column. The angle adjustment mechanism includes an adjustment rod rotatably connected to the top of the support column. A worm gear is fixedly connected to the rotating shaft end of the adjustment rod. A worm gear meshing with the worm gear is installed on the upper surface of the support column. An elastic element is fixedly connected to the top end of the adjustment rod.

[0006] The elastic element is provided with a clamping mechanism at its top. The clamping mechanism includes a lower clamping arm and an upper clamping arm. Multiple telescopic springs are fixedly connected to the inner walls of both the lower and upper clamping arms. A positioning post is fixedly connected to the top of each telescopic spring. The bottom surface of the lower clamping arm is fixedly connected to the elastic element. Positioning bolts are fixedly connected to both sides of the lower clamping arm.

[0007] The above scheme allows for flexible adjustment of the height of the clamping mechanism by setting a height adjustment mechanism, and flexible adjustment of the tilt angle of the clamping mechanism by setting an angle adjustment mechanism, thus improving the adaptability of the device support. The clamping mechanism, connected to the angle adjustment mechanism through elastic elements, can absorb and alleviate the stress generated by the pipeline due to external vibration or other environmental factors. Furthermore, by setting multiple telescopic springs and positioning columns, the clamping mechanism can adapt to the shape of vacuum pipeline bends of different sizes, and the telescopic springs can reduce the transmission of external vibrations to the pipeline, avoiding damage to the pipeline and improving the reliability of the device.

[0008] Furthermore, a partition is fixedly connected to the inner wall of the sleeve, and the threaded rod is rotatably sleeved in the inner wall of the partition.

[0009] The above solution can limit the downward movement of the support column, preventing excessive downward movement of the support column from damaging other components inside the sleeve.

[0010] Furthermore, two guide rods are fixedly connected to the upper surface of the partition, and the two sides of the support column are slidably sleeved on the outer surfaces of the two guide rods respectively.

[0011] The above solution makes the support column more stable when moving up and down, and facilitates the adjustment of the height of the support column extension.

[0012] Furthermore, a first bevel gear is fixedly connected to the bottom of the threaded rod, a rotating rod is rotatably sleeved on the bottom of the sleeve, a second bevel gear that meshes with the first bevel gear is fixedly connected to one end of the rotating rod, and a first knob is fixedly connected to the other end of the rotating rod.

[0013] With the above solution, turning the first knob can drive the second bevel gear to rotate, and the rotation of the second bevel gear can drive the first bevel gear to rotate, which in turn can drive the threaded rod to rotate, thus achieving the effect of conveniently rotating the threaded rod.

[0014] Furthermore, a second knob is fixedly connected to the shaft end of the worm gear.

[0015] The above solution increases the contact area at the worm shaft end, making it easier to rotate the worm.

[0016] Furthermore, the two sides of the upper clamping arm are sleeved on the outside of two positioning bolts, and each positioning bolt has a nut threaded onto its outer surface.

[0017] By using the above method, the upper clamping arm can be sleeved on both sides outside the two positioning bolts to place the bend of the vacuum pipe between the upper clamping arm and the lower clamping arm. Then, the nut is screwed on the positioning bolts and the nut is continued to be screwed on. This allows the upper clamping arm and the lower clamping arm to gradually clamp the bend of the vacuum pipe, which can fix the bend of the vacuum pipe and ensure that it is not displaced or deformed by external forces.

[0018] Furthermore, a shock-absorbing pad is fixedly connected to the bottom surface of the base, and the bottom surface of the shock-absorbing pad has evenly distributed grooves.

[0019] The above solutions can increase the friction between the base and the ground or load-bearing surface. At the same time, the groove design can make the shock-absorbing pad more elastic when bearing pressure or vibration. The air or space in the groove will be compressed when subjected to force, thereby absorbing and dispersing the impact force and improving the overall shock absorption performance.

[0020] Furthermore, positioning holes are provided at all four corners of the base.

[0021] The above method allows for easy fixing to the ground or load-bearing surface using bolts or welding, improving stability during support.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This vacuum pipe elbow support structure is characterized by the inclusion of height and angle adjustment mechanisms, allowing the clamping mechanism to flexibly adjust its height and tilt angle. This significantly improves the applicability and flexibility of the device. The clamping mechanism, through an elastic element connected to the angle adjustment mechanism, can effectively absorb and alleviate stress caused by external vibrations or other environmental factors. Furthermore, the clamping mechanism is equipped with multiple telescopic springs and positioning columns, which not only adapt to vacuum pipe elbows of different sizes and shapes but also buffer external vibrations through the telescopic springs, reducing the force transmitted to the pipe and thus avoiding potential damage to the pipe. This significantly enhances the reliability and stability of the device. Attached Figure Description

[0030] 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.

[0031] Please see Figure 1 and Figure 2 This embodiment of a vacuum pipe elbow support structure includes a base 1, a sleeve 2, and a height adjustment mechanism 3 disposed inside the sleeve 2. The height adjustment mechanism 3 includes a support column 301 sleeved on the inner wall of the sleeve 2 and a threaded rod 302 rotatably sleeved on the inner bottom wall of the sleeve 2. The outer surface of the threaded rod 302 is threadedly connected to the inner wall of the support column 301. A partition 303 is fixedly connected to the inner wall of the sleeve 2, and the threaded rod 302 is rotatably sleeved in the inner wall of the partition 303. By setting the partition 303, the downward movement of the support column 301 can be adjusted. To limit the downward movement of the support column 301 and prevent damage to other components inside the sleeve 2, two guide rods 304 are fixedly connected to the upper surface of the partition plate 303. The two sides of the support column 301 are slidably sleeved on the outer surfaces of the two guide rods 304. By setting the guide rods 304, the support column 301 can be more stable when moving up and down, and the height of the support column 301 can be easily adjusted. This allows the device to adjust the height of the support column 301 according to the actual position of the pipeline, thus improving the adaptability of the device.

[0032] Please see Figure 1 and Figure 2A first bevel gear 305 is fixedly connected to the bottom of the threaded rod 302. A rotating rod 306 is rotatably mounted on the bottom of the sleeve 2. One end of the rotating rod 306 is fixedly connected to a second bevel gear 307 that meshes with the first bevel gear 305. The other end of the rotating rod 306 is fixedly connected to a first knob 308. When the first knob 308 is rotated, the second bevel gear 307 can be driven to rotate. The rotation of the second bevel gear 307 can cause the first bevel gear 305 to rotate, which in turn causes the threaded rod 302 to rotate. This changes the direction of transmission and enables convenient rotation of the threaded rod 302. The effect of 02 is that the bottom surface of the base 1 is fixedly connected to the shock-absorbing pad 7. The bottom surface of the shock-absorbing pad 7 has evenly distributed grooves. By setting the shock-absorbing pad 7, the friction between the base 1 and the ground or load-bearing surface can be increased. At the same time, the groove design can make the shock-absorbing pad 7 more elastic when bearing pressure or vibration. The air or space in the groove will be compressed when subjected to force, thereby absorbing and dispersing the impact force and improving the overall shock absorption performance. The four corners of the base 1 are provided with positioning holes 8. By opening the positioning holes 8, it can be easily fixed to the ground or load-bearing surface by bolts or welding, improving the stability when supported.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The top of the support column 301 is provided with an angle adjustment mechanism 4. The angle adjustment mechanism 4 includes an adjustment rod 401 rotatably connected to the top of the support column 301. A worm gear 402 is fixedly connected to the shaft end of the adjustment rod 401. A worm 403 meshing with the worm gear 402 is installed on the upper surface of the support column 301. A second knob 404 is fixedly connected to the shaft end of the worm 403. By setting the second knob 404, the contact area of ​​the shaft end of the worm 403 can be increased, making it easier to rotate the worm 403. The combination of the worm 403 and the worm gear 402 has the effects of deceleration and self-locking. By rotating the worm 403, the worm gear 402 can be driven to rotate. By rotating the worm gear 402, the tilt angle of the adjustment rod 401 can be adjusted, so that the device can adjust the tilt angle of the adjustment rod 401 according to the actual curvature of the pipeline, thus improving the adaptability of the device.

[0034] Please see Figure 2 , Figure 3 and Figure 4An elastic element 5 is fixedly connected to the top of the adjusting rod 401. A clamping mechanism 6 is provided on the top of the elastic element 5. The clamping mechanism 6 includes a lower clamping arm 601 and an upper clamping arm 606. Multiple telescopic springs 602 are fixedly connected to the inner walls of both the lower and upper clamping arms 601 and 606. A positioning post 603 is fixedly connected to the top of each telescopic spring 602. The bottom surface of the lower clamping arm 601 is fixedly connected to the elastic element 5. By setting the elastic element 5, the stress generated by external vibration or other environmental factors in the pipeline can be absorbed and alleviated. By setting the telescopic springs 602 and positioning posts 603, the clamping mechanism 6 can adapt to bends in vacuum pipelines of different sizes. Simultaneously, the telescopic springs 602 can also alleviate vibrations. The upper clamping arm 606 is fitted over the two positioning bolts 604 on both sides to reduce the risk of pipeline damage caused by external vibration. The upper clamping arm 606 is fitted over the two positioning bolts 604 on both sides. Each positioning bolt 604 has a nut 605 threaded on its outer surface. Fitting the upper clamping arm 606 over the two positioning bolts 604 allows the bend of the vacuum pipeline to be placed between the upper clamping arm 606 and the lower clamping arm 601. Then, the nut 605 is screwed onto the positioning bolts 604 and the nut 605 is continued to be screwed on. This allows the upper clamping arm 606 and the lower clamping arm 601 to gradually clamp the bend of the vacuum pipeline, which can fix the bend of the vacuum pipeline and ensure that it is not displaced or deformed by external forces.

[0035] In this embodiment, a vacuum pipe elbow support structure allows for flexible adjustment of the height of the clamping mechanism 6 via a height adjustment mechanism 3 and flexible adjustment of the tilt angle of the clamping mechanism 6 via an angle adjustment mechanism 4, thus improving the adaptability of the support device. The clamping mechanism 6, connected to the angle adjustment mechanism 4 via an elastic element 5, can absorb and alleviate the stress generated by the pipe due to external vibration or other environmental factors. Furthermore, the clamping mechanism 6, by incorporating multiple telescopic springs 602 and positioning posts 603, can adapt to the shape of vacuum pipe elbows of different sizes and mitigate the transmission of external vibrations to the pipe through the telescopic springs 602, preventing damage to the pipe and improving the reliability of the device.

[0036] The working principle of the above embodiment is as follows: The device is positioned at a suitable location on the ground. Then, the first knob 308 is rotated to adjust the height of the support column 301. When the first knob 308 rotates, it drives the second bevel gear 307 to rotate. The rotation of the second bevel gear 307 drives the threaded rod 302 to rotate via the first bevel gear 305. When the threaded rod 302 rotates, it causes the support column 301 to move up and down on the inner wall of the sleeve 2, thereby adjusting the extension height of the support column 301 according to the position of the vacuum pipe bend. Next, the second knob 404 can be rotated to adjust the tilt angle of the adjusting rod 401. When the second knob 404 rotates, it drives the worm gear 403 to rotate. The rotation of the worm gear 403 drives the adjusting rod 401 to rotate, thereby adjusting the tilt angle of the adjusting rod 401. In this way, the height and tilt angle of the lower clamping arm 601 can be adjusted by the height adjustment mechanism 3 and the angle adjustment mechanism 4. Then, the lower clamping arm 601 is placed below the vacuum pipe bend and in contact with the vacuum pipe bend. Then, the two sides of the upper clamping arm 606 are fitted onto the two positioning bolts 604, so that the upper clamping arm 606 is located above the vacuum pipe bend. Then, the nuts 605 can be tightened onto the positioning bolts 604 one by one, so that the upper clamping arm 606 gradually moves towards the lower clamping arm 601. The position of the upper clamping arm 606 can be limited by the nuts 605, so that the vacuum pipe bend can be clamped by the lower clamping arm 601 and the upper clamping arm 606. The elastic element 5 and the telescopic spring 602 can effectively reduce the risk of pipe damage caused by external vibration and improve the reliability of the device.
