Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to a low-friction composite pipe sliding support. Background Technology

[0002] Modern pipeline systems are widely used, and temperature changes in the medium within the pipeline cause thermal expansion and contraction, affecting the pipeline and its supporting structure. While traditional pipeline sliding supports can generally meet the sliding requirements of pipelines, they are significantly inadequate when dealing with large displacements caused by factors such as thermal expansion and contraction. The support height of traditional sliding supports is usually fixed, and after pipeline displacement, the contact state between the support and the pipeline may change, potentially leading to unstable support and increasing the risk of pipeline system vibration and stress concentration. In severe cases, this can cause pipeline deformation, support damage, or even pipeline leaks, posing a threat to the safety of industrial production.

[0003] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a low-friction composite pipe sliding support in order to achieve a more practical purpose. Utility Model Content

Lower arc-shaped frames are installed on both sides of the upper surface of the base. Upper arc-shaped frames are correspondingly arranged above the two lower arc-shaped frames. The upper and lower arc-shaped frames on the corresponding side are connected by bolts. The pipe body is arranged between the two sets of upper and lower arc-shaped frames. The base has an inner cavity, and a lower support assembly is arranged inside the inner cavity. An upper support assembly is arranged above the pipe body.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides a low-friction composite pipe sliding support, including a base 1 and a mounting plate 2 installed at the bottom for fixing to other parts. Lower arc-shaped frames 5 are installed on both sides of the upper surface of the base 1. Upper arc-shaped frames 4 are correspondingly arranged above the two lower arc-shaped frames 5. Bolts 6 are connected between the upper arc-shaped frames 4 and the lower arc-shaped frames 5 on the corresponding side. The pipe body 3 is arranged between the two sets of upper arc-shaped frames 4 and lower arc-shaped frames 5. An inner cavity 7 is provided inside the base 1. A lower support assembly is provided inside the inner cavity 7. An upper support assembly is provided above the pipe body 3. The upper support assembly and the lower support assembly jointly support the pipe body 3 to prevent it from detaching and shifting.

[0025] The lower support assembly includes a vertical rod 11, with a first spring 12 sleeved on the outer side of the vertical rod 11. A rod sleeve 10 is slidably installed on the outer wall of the vertical rod 11. The top of the first spring 12 is fixed to the bottom of the rod sleeve 10. A connecting plate 9 is installed on the top of the rod sleeve 10, and a first support frame 8 is installed on the top of the connecting plate 9. The first support frame 8 abuts against the lower part of the pipe body 3. The lower support assembly also includes two sliding grooves 16, which are respectively located on both sides of the base 1. A slider 13 is slidably installed on the inner wall of each of the two sliding grooves 16. The same side of each slider 13 is fixed to the connecting plate 9. A pressing block 15 for pressing is installed on one side of each slider 13, and a limit hole 14 is opened on one side of each slider 13. The first spring 12 applies pressure to the rod sleeve 10, causing the rod sleeve 10 to drive the connecting plate 9 and the first support frame 8 to support the lower part of the pipe body 3.

[0026] The two bases 1 have grooves 17 on both sides. A second spring 18 is installed on one side of the inner wall of each groove 17. A wedge block 19 is installed on the opposite side of each second spring 18. The two wedge blocks 19 are located below the corresponding side slide groove 16. A wedge-shaped surface is provided on one side of the upper surface of each wedge block 19. By setting the wedge blocks 19 and the second springs 18, pressing the pressing block 15 drives the slider 13 to slide on the inner wall of the slide groove 16, so that the limiting hole 14 engages with the corresponding wedge block 19, causing the first support frame 8 to move down and be fixed.

[0027] The pipe body 3 is equipped with a connecting frame 20 on top. The bottom of the connecting frame 20 is fixed to two upper arc-shaped frames 4. The inner top of the two connecting frames 20 is equipped with a cylinder 21. The output end of the cylinder 21 is equipped with a second support frame 22. The second support frame 22 is set to abut against the top of the pipe body 3. Through the cooperation of the cylinder 21 and the second support frame 22, the second support frame 22 can support and abut against the top of the pipe body 3. Through cooperation with the first support frame 8, the device can always maintain stable support for the pipe, avoid the arc-shaped frame from detaching from the pipe due to pipe displacement, thereby extending the service life of the pipe and the support, and improving the safety and reliability of the entire pipeline system.

[0028] The contact surfaces between the first support frame 8 and the second support frame 22 and the pipe body 3 are both set as arc-shaped surfaces, which makes it easier to support the pipe body 3.

[0029] The inner wall of the sleeve 10 and the bottom of the connecting plate 9 are connected by a through groove, and the size of the through groove is adapted to the vertical rod 11. The through groove allows the vertical rod 11 to freely enter and exit the sleeve 10.

[0030] The two limiting holes 14 are configured to fit the size of the wedge block 19. The connecting plate 9 is fixed by the locking of the limiting holes 14 and the wedge block 19. The locking of the limiting holes 14 and the wedge block 19 can be released when needed.

[0031] The working principle of this embodiment is as follows: A first spring 12 is located outside the vertical rod 11 in the inner chamber 7. Its top is connected to the rod sleeve 10. The connecting plate 9 on the rod sleeve 10 drives the first support frame 8 to abut against the bottom of the pipe body 3. Under the pressure of the first spring 12, lower support is achieved. The connecting frame 20 above the pipe body 3 is fixed to the upper arc-shaped frame 4. A second support frame 22 is installed at the output end of the top cylinder 21 inside the upper arc-shaped frame 4. The operation of the cylinder 21 causes the second support frame 22 to abut against the top of the pipe body 3, cooperating with the lower support assembly to ensure stable support. The specific operation of the lower support assembly is as follows: Pressing the pressing block 15 drives the slider 13 to slide within the slide groove 16. The slider 13 drives the connecting plate 9 to descend, thereby driving the first support frame 8 to abut against the bottom of the pipe body 3. As the first support frame 8 descends, the first support frame 8 drives the sleeve 10 to slide on the outer wall of the vertical rod 11, thereby squeezing the first spring 12 until the limiting hole 14 contacts the wedge-shaped surface on one side of the wedge block 19. Under the action of the second spring 18, the wedge block 19 engages with and is fixed to the limiting hole 14. The elastic force of the second spring 18 keeps the wedge block 19 in a limiting position on the slider 13, thereby fixing the position of the first support frame 8. When it is necessary to release the limiting position, press the wedge block 19 to separate the limiting hole 14 from the wedge block 19. The entire support, through the above principle, ensures the stability of the pipeline body 3, avoids problems caused by displacement, extends the service life of the pipeline and the support, and improves the safety and reliability of the pipeline system.

Many modifications and variations will be apparent to those skilled in the art.
