Description

Technical Field

[0001] The invention relates to the technical field of supports and hangers, and in particular to a spring support and hanger for thermal displacement of pipelines. Background Art

[0002] In the modern industrial field, pipeline systems are widely used in many industries such as petrochemicals, electric power, metallurgy, etc., and play a vital role. However, due to the frequent and large changes in the temperature of the medium in the pipeline, the problem of pipeline thermal displacement has become one of the key factors affecting the safe and stable operation of the pipeline system.

[0003] In the related art, supports and hangers are fixedly connected to the pipelines through clamps to form a whole, which is then installed on the supporting building to provide support for the pipelines. However, due to the long-term flow of medium inside the pipelines and changes in the regional temperature or ambient temperature, thermal stress will be generated in the pipelines. Under the action of thermal stress, the pipeline will expand and contract axially due to thermal expansion and contraction, which is thermal displacement of the pipeline. On the one hand, thermal displacement of the pipeline will force the supports and hangers to shift in the direction of the axial expansion and contraction of the pipeline, causing the installation point of the supports and hangers and the supporting building to loosen or even fall off, which may eventually damage the pipeline; on the other hand, it may cause the pipeline to deform or rupture, or even cause medium leakage at the pipeline connection, affecting the normal operation of the entire production system.

[0004] Therefore, how to effectively solve the problem of pipeline thermal displacement, improve the safety and reliability of the pipeline system, ensure the safe operation of the pipeline system, and extend the service life of the pipeline is an issue that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In order to effectively solve the problem of pipeline thermal displacement, improve the safety and reliability of the pipeline system, ensure the safe operation of the pipeline system, and extend the service life of the pipeline, the present application provides a spring support and hanger for pipeline thermal displacement.

[0006] The present application provides a spring support and hanger for pipeline thermal displacement, which adopts the following technical solution:

[0007] A spring support and hanger for thermal displacement of a pipeline comprises a mounting seat, a support rod is slidably connected to the mounting seat, a longitudinal elastic mechanism is elastically connected between the support rod and the mounting seat, a circumferential elastic mechanism is elastically connected to the end of the support rod away from the mounting seat, a support seat is fixedly connected to the circumferential elastic mechanism, a transverse elastic mechanism is fixedly connected to the support seat, two symmetrically arranged connecting pipes are sealingly and slidably connected to the transverse elastic mechanism, and the connecting pipes are detachably and sealingly connected to the pipeline.

[0008] By adopting the above technical scheme, the spring support bracket can be fixedly installed as a whole on a supporting foundation such as a building by using the mounting seat, and then the connecting pipe is used to seal and connect with the pipeline, and the transverse elastic mechanism can be strung between the two pipelines. When the pipeline has thermal displacement during operation, the pipeline can drive the connecting pipe to slide on the transverse elastic mechanism accordingly, thereby compensating for the thermal displacement of the pipeline; at the same time, the longitudinal elastic mechanism can be used to buffer the vibration caused by the medium flowing inside the pipeline for a long time, which not only effectively solves the problem of thermal displacement of the pipeline, but also improves the safety and reliability of the pipeline system, ensures the safe operation of the pipeline system, and is conducive to extending the service life of the pipeline.

[0009] Furthermore, the longitudinal elastic mechanism includes a first longitudinal spring, which is fixedly installed inside the mounting seat, the bottom of the first longitudinal spring is fixedly connected to the mounting seat, the top of the first longitudinal spring is fixedly connected to a sliding seat, the sliding seat is slidably connected to the mounting seat, a locking assembly is provided between the sliding seat and the support rod, and the sliding seat and the support rod are fixedly connected via the locking assembly.

[0010] By adopting the above technical solution, the vibration generated by the medium flowing inside the pipeline for a long time can be transmitted to the first longitudinal spring through the sliding seat and the support rod. The elasticity of the first longitudinal spring can effectively buffer the vibration, thereby avoiding direct vibration impact on the mounting seat and the support foundation, and effectively ensuring the firmness and stability of the connection between the mounting seat and the support foundation.

[0011] Furthermore, the mounting seat is provided with a plurality of sliding grooves which are centrally symmetrical and vertically arranged, and a slider is fixedly connected to the sliding seat corresponding to the sliding groove. The slider is vertically slidably connected to the mounting seat via the sliding groove, and positioning blocks are detachably connected to the two ends of the slider corresponding to the inside of the sliding groove.

[0012] By adopting the above technical solution, the stability between the sliding seat and the mounting seat can be effectively improved by utilizing the cooperative sliding connection between the slider and the slide groove, and the installation position of the sliding seat can be effectively fixed by utilizing the positioning block. During the installation process, the preload of the first longitudinal spring can be set by simply setting the size of the positioning block.

[0013] Furthermore, a guide hole is opened in the axial direction of the lower end of the support rod, a guide rod is fixedly connected to the mounting seat corresponding to the guide hole, the lower end of the guide rod is fixedly connected to the mounting seat, the outer side surface of the guide rod is slidably connected to the inner wall surface of the guide hole, and a second longitudinal spring is abutted and connected between the upper end of the guide rod and the inner end of the guide hole.

[0014] By adopting the above technical solution, the guide rod can be used to ensure that the sliding between the sliding seat and the mounting seat is more stable. At the same time, the second longitudinal spring can be used to conveniently adjust the position of the support rod during the installation process on the one hand, and on the other hand, it can assist the first longitudinal spring in buffering and absorbing the vibration generated by the pipeline during operation, thereby further ensuring the safety and reliability of the pipeline system.

[0015] Furthermore, the locking assembly includes a locking rod, which has a driving part, an external threaded part, a long tooth part, and a pressing part. The driving part and the pressing part are respectively arranged at two end parts of the locking rod, and the external threaded part and the long tooth part are sequentially arranged on the outer periphery of the locking rod along the axial direction of the locking rod. A plurality of locking rods are centrally symmetrically installed inside the sliding seat, a screw hole is provided on the sliding seat corresponding to the locking rod, an annular groove is provided inside the sliding seat corresponding to the long tooth part, a gear ring is slidably connected inside the annular groove, and the long tooth parts on all the locking rods are meshed with the gear ring, and the pressing part is abutted against a pressure plate, and the pressure plate is abutted against the outer periphery of the support rod.

[0016] By adopting the above technical scheme, the locking rod can be used to press the top pressure plate against the outer periphery of the support rod, thereby forming a fixed connection between the support rod and the sliding seat. During the working process, the locking rod can be driven to rotate by an external rotating tool through the driving part. During the rotation process, the locking rod can make the locking rod axially move by the matching connection between the external threaded part and the screw hole, and in the process of rotation of the locking rod, the long tooth part can drive the gear ring to rotate, and the gear ring can drive other locking rods engaged with it to rotate synchronously. Therefore, only any one of the locking rods needs to be twisted to drive all the locking rods to rotate synchronously. In this way, on the one hand, the position of the support rod can be quickly adjusted during the installation process, and on the other hand, multiple centrally symmetrical locking rods can be used to synchronously lock the support rod during the installation process, thereby realizing automatic centering and ensuring the stability of the fixed connection between the support rod and the sliding seat.

[0017] Furthermore, the circumferential elastic mechanism includes a fixed plate, which is fixedly connected to the top end of the support rod, and the bottom of the support seat is fixedly connected with a bottom cover corresponding to the fixed plate. The outer side surface of the fixed plate is fixedly connected with a plurality of spring plates in a centrally symmetrical manner, and one end of the spring plate away from the fixed plate is fixedly connected to the bottom cover.

[0018] By adopting the above technical solution, the spring sheet can be used to form an elastic connection between the fixed disk and the support seat. When the two pipes are not coaxially connected during operation, the thermal displacement generated by the pipes will drive the two pipes to generate bending moments with each other. The elastic connection between the fixed disk and the support seat can buffer and compensate for the bending moments, thereby achieving compensation for the thermal displacement generated by the non-coaxially connected pipes, and further improving the safety and reliability of the pipeline system.

[0019] Furthermore, the transverse elastic mechanism includes an outer sleeve, the outer side surface of the outer sleeve is fixedly connected to the support seat near the middle thereof, the inner sleeve is slidably connected to the inside of the outer sleeve, the two connecting tubes are symmetrically inserted inside the inner sleeve, the outer side surface of the inner sleeve is fixedly connected to a limiting ring near the middle thereof, both end surfaces of the limiting ring are fixedly connected to a first transverse spring, and the end of the first transverse spring away from the limiting ring is fixedly connected to the outer sleeve.

[0020] By adopting the above technical solution, the outer sleeve and the inner sleeve are elastically connected by using the first transverse spring, which can not only buffer the vibration of the inner sleeve during operation, but also further increase the compensation amount for the thermal displacement of the pipeline when one of the connecting pipes slides to the extreme position, thereby further ensuring the stability and reliability of the pipeline system.

[0021] Furthermore, a second transverse spring is connected between the inner ends of the two connecting tubes located inside the inner sleeve, and installation grooves are provided at both ends of the inner sleeve corresponding to the connecting tubes. A damping ring is fixedly and sealedly connected in the installation groove, and a convex ring is centrally arranged on the inner side surface of the damping ring. The damping ring is sealingly and slidingly connected to the connecting tube via the convex ring.

[0022] By adopting the above technical solution, the second transverse spring can absorb the vibration generated by the fluid medium, reducing the vibration force generated by the fluid on the pipeline, and can elastically connect the two connecting pipes, effectively perform elastic buffering when compensating for the thermal displacement generated by the pipeline, and ensure stability and reliability when compensating for the thermal displacement. The damping ring can seal between the connecting pipe and the inner sleeve, thereby preventing the fluid medium from leaking from between the connecting pipe and the inner sleeve, ensuring the stability and safety of the pipeline system.

[0023] Furthermore, a first annular cavity and a second annular cavity are opened in parallel inside the damping ring, a first connecting hole is opened on the damping ring corresponding to the first annular cavity, a second connecting hole is opened on the damping ring corresponding to the second annular cavity, a first pressure channel is opened on the inner sleeve corresponding to the first connecting hole, a second pressure channel is opened on the inner sleeve corresponding to the second connecting hole, the first pressure channel is sealedly connected to a first pressure member, the second pressure channel is sealedly connected to a second pressure member, and the first pressure member and the second pressure member are symmetrically arranged.

[0024] By adopting the above technical solution, the first pressure member can be used to apply pressure to the first annular cavity corresponding to the damping ring through the first pressure channel and the first connecting hole, and the first annular cavity will expand after being pressurized. The second pressure member can be used to apply pressure to the second annular cavity corresponding to the damping ring through the second pressure channel and the second connecting hole, and the second annular cavity will expand after being pressurized. The damping ring will expand after the first annular cavity and the second annular cavity are pressurized. The expansion of the damping ring can not only prevent the sealing performance of the connecting pipe and the inner sleeve from being affected by thermal deformation, but also increase the damping force of the damping ring on the connecting pipe, thereby offsetting the displacement force caused by thermal deformation, and further ensuring the stability and safety of the pipeline system.

[0025] Further, the first pressure member includes a first pressure cylinder, which is fixedly mounted on the inner sleeve, and the rodless chamber of the first pressure cylinder is sealed and fixedly connected to the first pressure channel, and the end of the piston rod of the first pressure cylinder is fixedly connected to a first positioning ring, and the first positioning ring is fixedly mounted on the connecting pipe; the second pressure member includes a second pressure cylinder, which is fixedly mounted on the inner sleeve, and the rodless chamber of the second pressure cylinder is sealed and fixedly connected to the second pressure channel, and the end of the piston rod of the second pressure cylinder is fixedly connected to a second positioning ring, and the second positioning ring is fixedly mounted on the connecting pipe, and the rodless chambers of the first pressure cylinder and the second pressure cylinder are both filled with pressure medium.

[0026] By adopting the above technical solution, the first pressure cylinder and the second pressure cylinder can be used to input the pressure medium inside the first pressure cylinder or the second pressure cylinder into the first annular cavity or the second annular cavity inside the damping ring by the axial movement caused by the thermal displacement of the pipeline. When the connecting pipe moves toward the inside of the inner sleeve, the pressure medium inside the first pressure cylinder will be input into the first annular cavity inside the damping ring through the first positioning ring. When the connecting pipe moves toward the outside of the inner sleeve, the pressure medium inside the second pressure cylinder will be input into the second annular cavity inside the damping ring through the second positioning ring. In this way, whether the connecting pipe is displaced by thermal expansion or cold contraction, the damping ring will be expanded accordingly, thereby increasing the damping force of the damping ring on the connecting pipe, which can not only effectively reduce the vibration caused by thermal displacement, but also reduce the vibration caused by thermal displacement to avoid fatigue damage to the pipeline and connecting parts, thereby ensuring the service life of the pipeline system. It also helps to control the displacement amount, and control the displacement amount within a reasonable range, which can ensure that the pipeline connected to the precision equipment will not cause excessive stress to the equipment due to thermal displacement, and ensure the normal operation of the pipeline system.

[0027] The beneficial effects achieved include at least the following:

[0028] 1. The present application can fix the spring support and hanger as a whole on a supporting foundation such as a building through the mounting seat, and then use the connecting pipe to seal and connect with the pipeline. The transverse elastic mechanism can be strung between the two pipelines. When the pipeline has thermal displacement during operation, the pipeline can drive the connecting pipe to slide on the transverse elastic mechanism accordingly, thereby compensating for the thermal displacement of the pipeline, effectively solving the problem of thermal displacement of the pipeline, which is beneficial to ensuring the safe operation of the pipeline system and extending the service life of the pipeline.

[0029] 2. The elasticity of the first longitudinal spring in the present application can effectively buffer the vibration generated by the medium flowing inside the pipeline for a long time, thereby avoiding direct vibration impact on the mounting seat and the support foundation, and can effectively ensure the firmness and stability of the connection between the mounting seat and the support foundation.

[0030] 3. The present application can form an elastic connection between the fixed disk and the support seat through the spring sheet, and the elastic connection between the fixed disk and the support seat can buffer and compensate for the bending moment, thereby compensating for the thermal displacement generated by the non-coaxially connected pipes, further improving the safety and reliability of the pipeline system.

The other end of the push rod 609 fixedly connected to the buffer ring 606 slidably connected to one connecting pipe 700 is fixedly connected to the other connecting pipe 700. A third transverse spring 610 is mounted on the push rod 609. One end of the third transverse spring 610 is fixedly connected to the connecting pipe 700, and the other end of the third transverse spring 610 is fixedly connected to the buffer ring 606 slidably connected to the connecting pipe 700.

The damping ring 702 can be used to seal between the connecting pipe 700 and the inner sleeve 602, thereby preventing the fluid medium from leaking from between the connecting pipe 700 and the inner sleeve 602, thereby ensuring the stability and safety of the pipeline system.

The damping ring 702 will expand after the first annular cavity 704 and the second annular cavity 705 are pressurized. The expansion of the damping ring 702 can not only prevent the connection pipe 700 and the inner sleeve 602 from affecting the sealing performance due to thermal deformation, but also increase the damping force of the damping ring 702 on the connection pipe 700, thereby offsetting the displacement force generated by thermal deformation, and further ensuring the stability and safety of the pipeline system.

[0064] The implementation principle of a spring support and hanger for thermal displacement of pipelines in the embodiment of the present application is as follows:

[0065] When installing the pipeline 800, it is only necessary to string the transverse elastic mechanism 600 between the two pipelines 800 through the connecting pipe 700. When the pipeline 800 has thermal displacement during operation, the pipeline 800 can drive the connecting pipe 700 to slide on the transverse elastic mechanism 600 accordingly, thereby compensating for the thermal displacement of the pipeline 800; at the same time, the longitudinal elastic mechanism 300 can buffer the vibration caused by the long-term flow of the medium inside the pipeline, which not only effectively solves the problem of thermal displacement of the pipeline, but also improves the safety and reliability of the pipeline system, ensures the safe operation of the pipeline system, and is conducive to extending the service life of the pipeline.

[0066] When the installation position of the pipe 800 needs to be adjusted during installation, or the pipe 800 needs to be corrected during use, it is only necessary to use an external rotating tool (such as an Allen wrench, an electric wrench, etc.) to insert the driving part 3041 and then drive the locking rod 304 to rotate. During the rotation process, the locking rod 304 can make the locking rod 304 move axially by the matching connection between the external threaded part 3042 and the screw hole 305, and in the process of rotation of the locking rod 304, the long tooth part 3043 can drive the ring gear 307 to rotate, and the ring gear 307 will drive the other locking rods 304 engaged with it to rotate synchronously. Therefore, only one of the locking rods 304 needs to be twisted to drive all the locking rods 304 to rotate synchronously. In this way, the locking of the support rod 200 is first released, and then the installation position of the support rod 200 and the pipe 800 is adjusted, and then the external rotating tool is used to lock the support rod 200. On the one hand, this design can quickly adjust the position of the support rod 200 during the installation process. On the other hand, during the installation process, multiple centrally symmetrical locking rods 304 can be used to synchronously lock the support rod 200, achieving automatic centering and ensuring the stability of the fixed connection between the support rod 200 and the sliding seat 302.

[0067] During operation, the first pressure cylinder 712 and the second pressure cylinder 714 can utilize the axial movement caused by the thermal displacement of the pipeline 800 to input the pressure medium in the first pressure cylinder 712 or the second pressure cylinder 714 into the first annular cavity 704 or the second annular cavity 705 of the damping ring 702. When the connecting pipe 700 moves toward the inner sleeve 602, the pressure medium in the first pressure cylinder 712 is input into the first annular cavity 704 of the damping ring 702 through the first positioning ring 713. When the inner sleeve 602 moves externally, the pressure medium inside the second pressure cylinder 714 will be input into the second annular cavity 705 inside the damping ring 702 through the second positioning ring 715. In this way, whether the connecting pipe 700 is displaced due to thermal expansion or cold contraction, the damping ring 702 will be expanded accordingly, thereby increasing the damping force of the damping ring 702 on the connecting pipe 700, which can not only effectively reduce the vibration caused by thermal displacement, but also reduce the vibration caused by thermal displacement to avoid fatigue damage to the pipeline and connecting parts, thereby ensuring the service life of the pipeline system. It also helps to control the displacement amount, and control the displacement amount within a reasonable range, which can ensure that the pipeline connected to the precision equipment will not cause excessive stress to the equipment due to thermal displacement, and ensure the normal operation of the pipeline system.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
