Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, specifically to a variable spring combination support for pipelines. Background Technology

[0002] With the continuous development of the petrochemical industry, the use of spring supports for pipeline installation and fixation has been widely applied in the petrochemical field.

[0003] Petrochemical pipelines typically transport various media with a certain weight, such as crude oil, refined oil, and chemical raw materials. The pipelines themselves also have a certain weight. Using spring supports can provide reliable support for the pipelines and reasonably transfer the weight of the pipelines and media to the building structure or foundation.

[0004] Spring supports also have a displacement compensation function for pipelines. When the pipeline is installed in an uneven location, the different elastic forces of each spring support can compensate for the pipeline to a certain extent. However, since the existing spring supports cannot adjust the degree of spring extension and contraction, multiple spring supports installed along the pipeline route will exert different forces on different positions of the pipeline. If the elastic forces of adjacent spring supports differ significantly, the pipeline between these two spring supports will bear a large tensile or compressive force, which may cause the pipeline to deform or even break under long-term action. Utility Model Content

If the elasticity of adjacent spring supports differs significantly, the part of the pipeline between these two supports will bear a large tensile or compressive force, which may cause the pipeline to deform or even break under long-term action.

[0039] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0042] like Figures 1 to 4 As shown, this utility model provides a variable spring combination support for pipes, including a sleeve 100, a load frame 101, a support spring 102, a pipe fixing component 103, and an adjustment assembly;

[0043] The top of the sleeve 100 is provided with a load frame 101, and the pipe fixing component 103 is provided on the top of the load frame 101. The load frame 101 can move along the height direction of the sleeve 100. The support spring 102 is provided inside the sleeve 100, and the two ends of the support spring 102 abut against the outer bottom wall of the load frame 101 and the inner bottom wall of the sleeve 100, respectively.

[0044] The bottom of the sleeve 100 is provided with an adjustment component, which is used to adjust the relative distance between the sleeve 100 and the load frame 101.

[0045] In this embodiment, the variable spring combination support for the pipeline includes a sleeve 100, a load frame 101, a support spring 102, a pipeline fixing component 103, and an adjustment component. In use, multiple variable spring combination supports are arranged along the pipeline's direction. The pipeline is fixed by the pipeline fixing component 103, causing the pipeline to press down on the load frame 101. Since the support spring 102 is located inside the sleeve 100, and both ends of the support spring 102 abut against the outer bottom wall of the load frame 101 and the inner bottom wall of the sleeve 100 respectively, after the pipeline is fixed, the relative distance between the sleeve 100 and the load frame 101 can be adjusted using the adjustment component located at the bottom of the sleeve 100. This ensures that the compression or extension distance of the support spring 102 on the pipeline within each variable spring combination support remains consistent, i.e., the extension and contraction depth of the support spring 102 remains consistent. This ensures that the elastic force of the support spring 102 on the pipeline remains consistent across each variable spring combination support, preventing pipeline deformation or even damage due to elastic force deviation.

[0046] Of course, the pipe fastener 103 uses a clamp and fixing bolts in combination, which is existing technology and will not be described in detail here.

[0047] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the adjusting assembly includes a first sleeve 200, a threaded rod 201 with opposite directions, and an adjusting element;

[0048] The first sleeve 200 is sleeved on the outside of the sleeve 100. The side wall of the first sleeve 200 is provided with a connecting hole. The two ends of the opposite threaded rod 201 are respectively rotatably connected to the connecting hole.

[0049] At least two adjusting components are provided. One end of each adjusting component is threaded to the opposite threaded rod 201, and the other end is connected to the outer bottom wall of the sleeve 100. The adjusting components can drive the sleeve 100 to slide along the height direction of the first sleeve 200.

[0050] The sleeve 100 has scale lines 202 on its side wall.

[0051] In this embodiment, preferably, the two adjusting members are symmetrically arranged. Since one end of the two adjusting members is threadedly connected to the opposite threaded rod 201, when in use, rotating the opposite threaded rod 201 can change the position of one end of the adjusting member through the threaded engagement. The length of the adjusting member remains unchanged. The other end of the adjusting member drives the sleeve 100 to slide along the height direction of the first sleeve 200. Since the pipe is fixed in the pipe fixing member 103 above the sleeve 100, it will press down on the load frame 101, so it cannot lift the load frame 101. Instead, it compresses or stretches the support spring 102. At the same time, it can be compared and adjusted with the scale line 202 set on the outside of the sleeve 100 so that the compression or stretching distance of each support spring 102 on the pipe is consistent.

[0052] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the adjusting component includes an adjusting sleeve 203 and an adjusting rod 204;

[0053] The inner wall of the adjusting sleeve 203 is threaded. The adjusting sleeve 203 is sleeved on the opposite threaded rod 201, and the adjusting sleeve 203 can be threadedly engaged with the opposite threaded rod 201. One end of the adjusting rod 204 is hinged to the adjusting sleeve 203, and the other end is hinged to the outer bottom wall of the sleeve 100.

[0054] In this embodiment, preferably, the adjusting component includes an adjusting sleeve 203 and an adjusting rod 204. The adjusting sleeve 203 is threaded on its inner wall and sleeved on the outer side of the opposite threaded rod 201. By threading the adjusting sleeve 203 and the opposite threaded rod 201, the position of the adjusting sleeve 203 can be changed when the opposite threaded rod 201 is rotated. Since the two ends of the adjusting rod 204 are hinged to the adjusting sleeve 203 and the outer bottom wall of the sleeve 100 respectively, the adjusting rod 204 is used to push the sleeve 100 upward or downward along the inside of the first sleeve 200, so that the compression or tension distance of the support spring 102 of each pipe variable spring combination bracket is consistent, so as to ensure that the elastic force of each support spring 102 on the pipe is consistent and to avoid the pipe deformation or even damage caused by the elastic force deviation.

[0055] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the adjustment assembly also includes an adjustment block 205. The two ends of the opposite threaded rod 201 protrude from the connecting hole, and the two ends of the opposite threaded rod 201 are respectively fixed with adjustment blocks 205.

[0056] In this embodiment, the two ends of the anti-threaded rod 201 are rotatably connected to the connecting hole and protrude from the connecting hole. Therefore, adjustment blocks 205 are fixed at both ends of the anti-threaded rod 201. Preferably, the adjustment blocks 205 are hexagonal blocks and are regular hexagonal, so that the adjustment blocks 205 can be clamped and rotated by tools such as wrenches, thereby driving the anti-threaded rod 201 to rotate synchronously, so as to adjust the position of the sleeve 100.

[0057] According to one embodiment provided by this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the variable spring combination support for the pipeline also includes a base plate 300 and auxiliary installation components;

[0058] The base plate 300 is located at the bottom of the first sleeve 200. The base plate 300 is rectangular in shape and is installed on the fixing surface by hexagonal bolts 301 located at its four apex corners.

[0059] The auxiliary installation component is located on the base plate 300 and is used to tighten four hexagonal bolts 301 at the same time.

[0060] In this embodiment, a base plate 300 is provided at the bottom of the first sleeve 200 for mounting the entire variable spring combination bracket of the pipe on a fixed surface, i.e., the ground. Preferably, the base plate 300 is rectangular and is mounted on the fixed surface by hexagonal bolts 301 located at its four apex. To facilitate installation, an auxiliary installation component is provided on the base plate 300 to tighten the four hexagonal bolts 301 at the same time. Using the auxiliary installation component for installation can effectively improve installation efficiency and reduce labor intensity.

[0061] According to one embodiment provided by this utility model, such as Figure 1 and Figure 3 As shown, the auxiliary installation components include a second sleeve 400 and a swivel sleeve 401;

[0062] The second sleeve 400 is sleeved on the outside of the first sleeve 200, and the second sleeve 400 can rotate along the radial direction of the first sleeve 200. The four apex corners of the base plate 300 are provided with screw holes, and a screw sleeve 401 is provided above the screw holes. The screw sleeve 401 is used to fasten the hexagonal bolt 301.

[0063] The bottom of the second sleeve 400 is fixedly provided with a first toothed ring 402, and the bottom of the sleeve 401 is fixedly provided with a second toothed ring 403. The first toothed ring 402 and the second toothed ring 403 mesh with each other.

[0064] In this embodiment, a second sleeve 400 is sleeved on the outside of the first sleeve 200. A first toothed ring 402 is fixed at the bottom of the second sleeve 400, and a second toothed ring 403 is fixed at the bottom of the rotating sleeve 401. Since the second sleeve 400 can rotate radially along the first sleeve 200, by rotating the second sleeve 400, the first toothed ring 402 and the second toothed ring 403 can be meshed together to drive the rotating sleeve 401 to rotate synchronously. This can simultaneously drive the hexagonal bolts 301 in the four rotating sleeves 401 to be bolted to the screw holes, so as to fix the base plate 300 to the fixed surface.

[0065] According to one embodiment provided by this utility model, such as Figure 1 and Figure 3 As shown, the sleeve 401 has a hexagonal groove 404, and the hexagonal bolt 301 is slidably bolted to the hexagonal groove 404. The depth of the hexagonal groove 404 is greater than the length of the hexagonal bolt 301.

[0066] In this embodiment, during use, four hexagonal bolts 301 are inserted into the hexagonal grooves 404 of the sleeve 401, causing the second sleeve 400 and the first toothed ring 402 to rotate. This allows the second toothed ring 403 to rotate synchronously, and the hexagonal grooves 404 in the sleeve 401 drive the four hexagonal bolts 301 to rotate simultaneously, thus tightening the four hexagonal bolts 301 at the same time. This achieves the effect of quickly fixing or removing the base plate 300.

[0067] Preferably, the hexagonal groove 404 is a regular hexagon that matches the top shape of the hexagonal bolt 301, and the depth of the hexagonal groove 404 is greater than the length of the hexagonal bolt 301 to ensure the fixing effect.

[0068] According to one embodiment provided by this utility model, such as Figure 1 and Figure 3 As shown, the outer wall of the second sleeve 400 is provided with a handle 405.

[0069] In this embodiment, a handle 405 is provided on the outer wall of the second sleeve 400 to facilitate the rotation of the second sleeve 400 and the first toothed ring 402. When in use, the second sleeve 100 and the first toothed ring 402 can be rotated through the handle 405, which saves time and effort.

[0070] According to one embodiment provided by this utility model, such as Figure 1 and Figure 4 As shown, the auxiliary installation assembly also includes a ring frame 406 and a clamping block 407. The ring frame 406 is located below the handle 405. The bottom wall of the ring frame 406 is fixed with a clamping block 407. The clamping block 407 corresponds one-to-one with the rotating sleeve 401. The clamping block 407 can be inserted into the hexagonal groove 404 along the height direction of the second sleeve 400.

[0071] In this embodiment, the ring frame 406 is located below the handle 405, and the clamping block 407 can be vertically inserted into the hexagonal groove 404. The clamping block 407 on the ring frame 406 presses the hexagonal bolt 301 into the hexagonal groove 404. Applying vertical downward pressure can make the hexagonal bolt 301 fit more tightly with the screw hole. During the tightening process, the friction between the threads is one of the key factors to ensure the tightness of the bolt connection. When there is a vertical downward force, the normal pressure between the threads will increase. As the normal pressure increases, the friction will also increase accordingly, thereby tightening the hexagonal bolt 301 more effectively and making the connection between the hexagonal bolt 301 and the screw hole of the base plate 300 and the fixed surface below the base plate more secure.

[0072] According to one embodiment provided by this utility model, such as Figure 1 and Figure 4 As shown, the auxiliary installation assembly also includes several guide telescopic rods 408 and compression springs 409. The guide telescopic rods 408 are arranged at intervals around the ring frame 406. One end of the guide telescopic rod 408 is connected to the ring frame 406, and the other end is connected to the top wall of the base plate 300. The compression spring 409 is sleeved on the outside of the guide telescopic rod 408, and both ends of the compression spring 409 abut against the ring frame 406 and the base plate 300, respectively.

[0073] In this embodiment, a guide telescopic rod 408 is also fixedly connected below the ring frame 406. The end of the guide telescopic rod 408 away from the ring frame 406 is fixedly connected to the base plate 300, and a compression spring 409 is sleeved on the outer side of the guide telescopic rod 408. The upper and lower ends of the compression spring 409 are fixedly connected to the ring frame 406 and the base plate 300, respectively. Specifically, the spring force of the compression spring 409 can make the compression block 407 on the ring frame 406 press the hexagonal bolt 301 into the hexagonal groove 404.

[0074] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
