[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0042] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0044] In the related art, when installing pipelines and vibration isolation brackets, due to the existence of manufacturing or installation deviations, the installation position of the pipeline is prone to offset during the actual installation of the pipeline and the vibration isolation bracket. Ultimately, the space around the pipeline does not meet the installation requirements of the vibration isolation bracket, making it difficult to install the vibration isolation bracket. The position of the pipeline and the vibration isolation bracket needs to be adjusted frequently. The offset of the pipeline position may also cause the coordination between the vibration isolation bracket and the pipeline after installation to not meet the process range, and even make the vibration isolation bracket difficult to install. The position of the vibration isolation bracket and the pipeline is inconvenient to adjust, and it is also difficult to ensure the installation position accuracy between the pipeline and the vibration isolation bracket during the adjustment process. There are technical problems that the installation and adjustment of the pipeline and the vibration isolation bracket are inconvenient and it is difficult to ensure the installation position accuracy of the pipeline and the vibration isolation bracket. The embodiment of the present application provides a pipeline assembly and a method for installing a pipeline assembly, which can at least solve the above technical problems to a certain extent.

[0045] The present application will be described below with reference to the accompanying drawings:

[0046] Figure 1 A schematic diagram showing the use status of a pipeline assembly in some embodiments or certain embodiments of the present application is shown. Figure 2 A schematic diagram of the structure of an adjustment bracket in some embodiments or certain embodiments of the present application is shown, referring to Figure 1 , 2 The embodiment of the present application provides a pipeline assembly, which is used to connect and position two pipelines, including:

[0047] The regulating tube 1 has two ends respectively used for coaxial connection with two pipelines.

[0048] The vibration isolation bracket 2 is sleeved and connected to a pipeline and is used to reduce vibration for the corresponding pipeline.

[0049] The adjusting bracket 3 includes a fixing part 31, a limiting structure 32 and a positioning part 33. The limiting structure 32 is used to be sleeved on the same pipeline with the vibration isolation bracket 2. The limiting structure 32 is movably arranged on the fixing part 31. The positioning part 33 is used to connect the positioning limiting structure 32 and the fixing part 31.

[0050] Taking two pipelines on a ship that need to be positioned and connected as an example, one of the pipelines can be connected and installed according to the specifications. On the basis of one of the pipelines, one end of the regulating pipe 1 is coaxially connected to the installed pipeline. The regulating pipe 1 can play a certain regulating and transitional role. The position of the other end of the regulating pipe 1 can be controlled according to demand, so that the other pipeline of the two pipelines has space to be connected to the other end of the regulating pipe 1, which is also convenient for the connection and installation of the other pipeline and the vibration isolation bracket 2 on the pipeline. While meeting the installation requirements of the other pipeline, the vibration isolation bracket 2 can provide normal shock absorption function for the corresponding pipeline. The pipeline installed by the vibration isolation bracket 2 is also provided with a limiting structure 32 of the adjusting bracket 3. The limiting structure 32 of the adjusting bracket 3 can be movably arranged on the fixing part 31 of the adjusting bracket 3. Therefore, before the vibration isolation bracket 2 is actually installed on the corresponding pipeline, the fixing part 31 can be connected and fixed to the deck or wall near the adjusting pipe 1 or a fixed device. The fixing part 31 cooperates with the limiting structure 32 to preliminarily limit the position of the pipeline, and then the limiting structure 32 of the pipeline is moved relative to the fixing part 31 for fine-tuning. Finally, when the position of the other pipeline meets the requirements, the positioning part 33 of the adjusting bracket 3 can be used to connect the positioning limiting structure 32 and the fixing part 31, so that the position of the limiting structure 32 relative to the fixing part 31 is fixed, and the position of the pipeline is fixed, and finally the vibration isolation bracket 2 is installed. During the whole process, the position of the pipeline and the vibration isolation bracket 2 can be flexibly adjusted, and the relative position between the pipeline and the adjustment tube 1 can be quickly located by adjusting the bracket 3, which is beneficial to improving the installation efficiency and installation position accuracy of the pipeline, the vibration isolation bracket 2 and related structures, and to a certain extent solves the technical problems of inconvenient installation and adjustment of the pipeline and the vibration isolation bracket 2 and difficulty in ensuring the installation position accuracy of the pipeline and the vibration isolation bracket 2.

[0051] It should be noted that the vibration isolation bracket 2 is usually provided with a buffering or shock-absorbing component for covering the pipeline. When the vibration isolation bracket 2 is installed on the pipeline, the buffering or shock-absorbing component requires a certain buffering or shock-absorbing position. Therefore, the installation of the vibration isolation bracket 2 and the pipeline needs to meet certain position requirements.

[0052] In some or certain embodiments, the vibration isolation bracket 2 may also be one of a common vibration isolation bracket, a single-isolator vibration isolation bracket, or a double-isolator vibration isolation bracket.

[0053] In some or certain embodiments, the limiting structure 32 is provided with two parallel rods 321 , each of which can slidably pass through the fixing member 31 along its own axis, and two positioning members 33 correspond to the rods 321 one by one and are threadedly connected, and the positioning members 33 are used to abut against the fixing member 31 .

[0054] The rod 321 of the limiting structure 32, the fixing member 31 and the positioning member 33 are in the above-mentioned matching relationship, so the two rods 321 of the limiting structure 32 can be locked on the fixing member 31 by the two corresponding positioning members 33. When it is necessary to adjust the position of the limiting structure 32 relative to the fixing member 31, the two positioning members 33 can be rotated synchronously relative to the rod 321, so that the limiting structure 32 and the rod 321 can move relative to the fixing member 31 along the axial direction of the rod 321, thereby achieving fine adjustment of the position of the pipeline set by the limiting structure 32. The accuracy of position adjustment can be improved, and it is easy to disassemble and assemble.

[0055] In some or certain embodiments, the fixing member 31 is provided with a strip hole 311 for the rod portion 321 to pass through and the length of the strip hole 311 extends along the radial direction of the rod portion 321 , and the width of the strip hole 311 is smaller than the minimum width of the positioning member 33 .

[0056] The rod 321 of the limiting structure 32 can pass through the strip hole 311 to achieve axial sliding relative to the fixing member 31. The length direction of the strip hole 311 extends along the radial direction of the rod 321, so the rod 321 can also move along the length direction of the strip hole 311, and the limiting structure 32 can move along the length direction of the strip hole 311 and the axial direction of the rod 321. The limiting structure 32 has a lot of adjustment space, which is convenient for adjusting the position of the limiting structure 32 and the pipeline connected to the limiting structure 32 according to needs, which is conducive to realizing rapid adjustment of the pipeline and improving the installation efficiency of the pipeline and the vibration isolation bracket 2. The width of the strip hole 311 is smaller than the minimum width of the positioning member 33, which is convenient for achieving abutment between the fixing member 31 and the positioning member 33.

[0057] In some or certain embodiments, the fixing member 31 may be provided with two strip holes 311 for two rods 321 to pass through respectively, and each rod 321 may be sleeved with two positioning members 33. In the axial direction of the rod 321, two positioning members 33 corresponding to the same rod 321 are clamped with the strip hole 311 corresponding to the rod 321. To facilitate adjustment of the position of the rod 321 and the limiting structure 32, each rod 321 is sleeved with two positioning members 33, and is threadedly matched with the positioning members 33, which can also make the position of the limiting structure 32 relative to the fixing member 31 more accurate.

[0058] Figure 3 A side view of a fixing member in some embodiments or certain embodiments of the present application is shown, Figure 4 A top view of a fixing member in some embodiments or certain embodiments of the present application is shown, combined with Figure 3and Figure 4 The fixing member 31 may include a support portion 312 and a mounting portion 313 both of which are L-shaped, the support portion 312 is connected to the mounting portion 313, and one end of the support portion 312 is fixedly connected to one side of the mounting portion 313, and the other side of the mounting portion 313 may be provided with a strip hole 311.

[0059] The structure of the fixing member 31 is as described above, and the preparation cost is low. It is easy to cooperate with the limiting structure 32, the overall volume occupied is small, and it can also flexibly adapt to a smaller space.

[0060] In some or certain embodiments, the positioning member 33 may also be a nut, or a cylindrical structure with an internal threaded hole, etc.

[0061] In some or certain embodiments, the fixing member 31 may also be block-shaped, and a protruding mounting portion 313 may be provided on the fixing member 31, and the mounting portion 313 may be provided with a strip hole 311. The fixing member 31 may also cooperate with the limiting structure 32, and the limiting structure 32 may also move relative to the limiting structure 32.

[0062] In some or certain embodiments, the limiting structure 32 may include:

[0063] The U-shaped rod 322 has rod portions 321 at both ends.

[0064] The limiting plate 323 is slidably mounted on the two rod portions 321 , and together with the U-shaped rod 322 , forms a through hole for mounting a pipeline.

[0065] The two locking nuts 324 are threadedly connected to the corresponding rods 321 in a one-to-one correspondence and are used to abut against the limiting plate 323 .

[0066] In the limiting structure 32, the limiting plate 323 is sleeved on the two rods 321 of the U-shaped rod 322, and can enclose a through hole for sleeved pipelines with the U-shaped rod 322, and the locking nut 324 is threadedly connected with the corresponding rod 321 and abuts against the limiting plate 323, so that the pipeline can be stuck at the bending part between the limiting plate 323 and the U-shaped rod 322, which is conducive to improving the connection tightness between the pipeline and the limiting structure 32, so as to ensure that the pipeline can move with the movement of the limiting structure 32. This structure can improve the versatility to a certain extent by adjusting the locking nut 324, so that pipelines of different diameters can pass between the limiting plate 323 and the U-shaped rod 322, and can also facilitate the separation of the U-shaped rod 322 and the limiting plate 323, so as to facilitate disassembly and assembly.

[0067] In some or certain embodiments, the limiting structure 32 may also be a plate-like structure, and the limiting structure 32 is sleeved on the corresponding pipeline through the through hole provided therein, and the limiting structure 32 may be provided with a plurality of plug holes, and the fixing member 31 may be provided with a groove corresponding to the limiting structure 32, and the limiting structure 32 may move in the groove, and the positioning member 33 may be a rod-like or strip-like structure, and the positioning member 33 is inserted into the groove of the fixing member 31 to insert into the plug hole, thereby completing the positioning of the limiting structure 32 and the fixing member 31. Alternatively, the limiting structure 32 may also be rotatably connected to one side of the fixing member 31, and the limiting structure 32 and the fixing member 31 may both be provided with a plurality of plug holes, and when the limiting structure 32 rotates a certain angle relative to the fixing member 31, the positioning member 33 may be inserted into the corresponding plug holes on the limiting structure 32 and the fixing member 31 in sequence. The limiting structure 32 can be moved relative to the fixing member 31, and the positioning member 33 can connect the positioning limiting structure 32 and the fixing member 31. The adjustment bracket 3 can be installed on the corresponding pipeline according to needs to adjust the position of the pipeline.

[0068] In some or certain embodiments, the adjusting tube 1 may be a flexible tube.

[0069] The regulating pipe 1, which is a flexible pipe, can absorb and disperse the vibration in the pipeline, and can improve the service life and stability of the pipeline in combination with the vibration isolation bracket 2. In addition, the flexible pipe can have a certain displacement compensation, which is also conducive to flexibly adapting to different installation environments of the pipeline.

[0070] In some or certain embodiments, the regulating pipe 1 may also be a curved pipe, which may also be applicable to pipeline connection and regulation in certain environments.

[0071] Figure 5 A flow chart of a method for installing a pipeline assembly in some embodiments or certain embodiments of the present application is shown, with reference to Figure 5 Based on the same inventive concept, the present application also provides an installation method of the pipeline assembly as described above, dividing the two pipelines into a fixed pipeline and an installation pipeline, and the installation method includes:

[0072] S101: Fix one end of the fixed pipeline.

[0073] S102: Coaxially connect one end of the regulating pipe to the other end of the fixed pipe.

[0074] S103: Sleeve the limiting structure onto the installation pipeline.

[0075] S104: Fix the fixing member to the installation area adjacent to the adjusting pipe.

[0076] S105: Move the limiting structure relative to the fixing member to adjust the installation pipeline to meet the installation requirements.

[0077] S106: Connect the installation pipeline to the other end of the regulating pipe.

[0078] S107: Install a vibration isolation bracket on the installation pipeline and fix the vibration isolation bracket on the installation area.

[0079] The specific structure of the pipeline assembly and its corresponding technical effects can be referred to above and will not be repeated here. The two pipelines are divided into a fixed pipeline and an installation pipeline for ease of understanding only. After the fixed pipeline is installed, the adjusting pipe is first connected, and then the limiting structure of the adjusting bracket is sleeved onto the installation pipeline, and the fixing part of the adjusting bracket is fixed to the installation area adjacent to the adjusting pipe to complete the preliminary positioning of the installation pipeline. Finally, by adjusting the position of the limiting structure relative to the fixing part, the installation pipeline can be adjusted to meet the installation requirements. After the installation pipeline meets the installation requirements, first connect the installation pipeline to the other end of the adjusting pipe, and finally connect the installation pipeline to the vibration isolation bracket. The installation efficiency is high and the installation is fast, and the accuracy of the relative position of the vibration isolation bracket and the installation pipeline can be ensured.

[0080] For ease of understanding, Figure 1 The two pipelines in the figure are marked as a fixed pipeline 10 and an installation pipeline 20 respectively.

[0081] In some or certain embodiments, the fixed pipeline may be a pipe with a float valve machine on a ship, or may be some pipelines connected to other equipment or other fixed pipelines.

[0082] In some or certain embodiments, the installation area adjacent to the adjusting tube may be an area adjacent to the other end of the adjusting tube, such as an area 40 mm to 80 mm away from the other end of the adjusting tube. The adjusting tube end flange is centered and offset outwards within a range of 40 mm to 80 mm to be installed perpendicular to the installation pipeline. It needs to be connected to the other end of the adjusting tube. Therefore, after the position of the adjusting tube is determined, the fixing part of the adjusting bracket can be set in the attachment area close to the other end of the adjusting tube, which is more accurate in positioning and convenient for adjusting the position of the installation pipeline.

[0083] In step S104 of some or certain embodiments, fixing the fixing member to the installation area adjacent to the regulating tube includes:

[0084] Spot weld the fixings to the mounting area.

[0085] The fixing parts of the adjusting bracket are fixed to the installation area by spot welding, which can ensure that the adjusting bracket supports the installation pipeline. The adjusting bracket can also be separated from the installation area by cutting the spot welding parts, which is conducive to the reuse of the adjusting bracket.

[0086] It should be noted that the installation area may be a ship deck, a bulkhead or a fixed-position equipment, etc.

[0087] In some or certain embodiments, the adjusting tube may be installed so that the other end of the adjusting tube faces a position with a larger installation space and then connected to the vibration isolation bracket, so that the installation pipeline and the vibration isolation bracket can be installed in a relatively sufficient space.

[0088] In step S105 of some or certain embodiments, the limiting structure is moved relative to the fixing member to adjust the installation pipeline to meet the installation requirements, including:

[0089] With the other end of the adjusting pipe as the installation reference, the limiting structure is moved relative to the fixing part until the pipe opening of the installation pipeline meets the installation requirements relative to the installation reference.

[0090] After the adjusting tube is installed, the other end of the adjusting tube can be used as an installation reference for the installation pipeline to facilitate adjustment of the connection position of the installation pipeline.

[0091] In some or certain embodiments, the installation pipeline can be adjusted until the pipe opening of the installation pipeline is concentric with the other end of the adjustment pipe, and the deviation of parallelism and concentricity is -1mm to +1mm, which can effectively improve the installation position accuracy of the installation pipeline.

[0092] In step S106 of some or certain embodiments, the regulating pipe and the installation pipeline may be connected via a flange and a fastener, and the distance between the flange of the regulating pipe and the flange of the installation pipeline is less than 3 mm, which can improve the accuracy of the installation position.

[0093] It should be noted that the parallelism, concentricity and the distance between the two flanges can be measured by corresponding measuring instruments respectively.

[0094] In step S107 of some or certain embodiments, installing a vibration isolation bracket on the installation pipeline and fixing the vibration isolation bracket on the installation area may include:

[0095] The vibration isolation bracket is sleeved on the installation pipeline, the vibration isolation bracket can be fixed in the installation area, and the adjustment bracket is located between the vibration isolation bracket and the adjustment pipe.

[0096] The vibration isolation bracket is installed on the installation pipeline, and the adjustment bracket is located between the vibration isolation bracket and the adjustment pipe. The adjustment bracket has completed the position adjustment of the installation pipeline, and can provide fixed support for the installation pipeline at this time, so that the vibration isolation pipeline is set at a position where the installation pipeline is far away from the adjustment pipe, which can facilitate the installation of the vibration isolation bracket and will not affect the connection between the installation pipeline and the adjustment pipe. It can ensure that after the vibration isolation bracket is installed, the installation position accuracy of the installation pipeline relative to the adjustment pipe and the vibration isolation bracket relative to the installation pipeline are both good. The connection between the vibration isolation bracket and the installation area can be fixed by welding.

[0097] In some or certain embodiments, the distance between the fixing member and the pipe opening of the installation pipeline may be 40 mm to 80 mm, which is beneficial to improving the installation accuracy of the installation pipeline and facilitating the rapid installation of the installation pipeline.

[0098] In some or certain embodiments, the distance between the vibration isolation bracket and the pipe opening of the installation pipeline can be 80 mm to 130 mm, which is beneficial to ensure the shock absorption effect of the installation pipeline, reduce the impact of vibration on different pipeline connections, and improve the use stability of the pipeline assembly.

[0099] In some or certain embodiments, after installing the pipeline and setting the vibration isolation bracket and fixing the vibration isolation bracket to the installation area, the installation method of the pipeline assembly may further include:

[0100] Separate the limiting structure and installation pipeline.

[0101] The limiting structure and the installation pipeline are separated, and the adjustment bracket can be reused, which is energy-saving and environmentally friendly.

[0102] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0103] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
