Description

Technical Field

[0001] This utility model relates to the field of pipeline system technology, specifically to a support device for long-distance oil pipelines. Background Technology

[0002] Pipelines for transporting crude oil or refined oil over long distances can reach thousands of kilometers. During oil transportation, oil pipelines are usually laid off the ground. Therefore, oil pipeline support devices need to be installed at intervals to support the oil pipeline. Utility model with announcement number CN215568473U discloses an oil pipeline support device that is easy to assemble and disassemble (hereinafter referred to as prior art 1), which includes a support base. The top of the support base is movably connected to a lower pipe support plate. The upper pipe support plate is movably connected to an upper pipe fixing plate. Connecting devices are provided on the left and right sides of the upper pipe fixing plate and the lower pipe support plate. The bottom of the support base is provided with a base, and the top of the base is provided with support columns on both sides to support the connecting devices.

[0003] While existing technology 1 describes a convenient oil pipeline support device, during pipeline operation, the flow of the medium (crude oil, natural gas, etc.) within the pipeline experiences periodic pulsations, which can cause pipeline vibration. If the natural frequency of the support device is close to the pipeline vibration frequency, resonance will occur, amplifying the vibration amplitude. This leads to fatigue wear at the connection between the support device and the pipeline (such as loose bolts and weld cracking), severely affecting the safety of pipeline operation. Utility Model Content

[0004] The purpose of this utility model is to provide a support device for long-distance oil pipelines, which can solve the problem in the prior art where the natural frequency of the support device is close to the vibration frequency of the pipeline, resulting in resonance and amplification of the vibration amplitude; causing fatigue wear at the connection between the support device and the pipeline, which affects the safety of pipeline operation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A support device for a long-distance oil pipeline includes a support base and a clamp assembly, wherein the clamp assembly is mounted on the support base, and the support base is slidably mounted on a steel beam; The clamp assembly includes a locking element and two symmetrically arranged clamp bodies, one of which is connected to the support base, and the two clamp bodies form an installation area for placing the pipe; the two clamp bodies are detachably connected to each other via the locking element. Each clamp body is equipped with a buffer mechanism, and the support base is equipped with a first limiting part for cooperating with the steel beam.

[0006] Preferably, the buffer mechanism includes a buffer pad and a buffer block. The buffer pad is installed in the clamp body. The buffer pad is provided with a sliding groove. The buffer block is slidably installed in the sliding groove. An elastic element is installed in the sliding groove. The buffer block is connected to the buffer pad through the elastic element.

[0007] Preferably, the clamp body is provided with a guide groove, the buffer pad is fixedly connected with a guide block, and the buffer pad is slidably connected to the guide groove through the guide block.

[0008] Preferably, a second limiting part is symmetrically connected to the buffer pad.

[0009] Preferably, there are two clamp assemblies, which are symmetrically installed on the support base.

[0010] Preferably, the clamp body is symmetrically connected with connecting ears, the locking member is threadedly connected to the connecting ears, and the two connecting ears are detachably connected through the locking member.

[0011] Preferably, the connecting ear is tilted.

[0012] Preferably, the locking member is provided with a stepped groove, and the connecting ear is slidably connected to the stepped groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In this invention, when the pipeline vibrates during operation, the vibration energy is transferred to the buffer mechanism. The buffer mechanism consumes energy through deformation, reduces the vibration amplitude, and avoids resonance amplification. When the pipeline expands or contracts axially due to temperature changes, the pipeline drives the clamp assembly and the support to slide synchronously along the groove, realizing adaptive adjustment of axial displacement. The first limiting part on the support ensures that the sliding is within a safe range and prevents excessive pipeline displacement. Attached Figure Description

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] See Figures 1-3 This embodiment discloses a support device for a long-distance oil pipeline, characterized in that it includes a support base 101 and a clamp assembly 102, wherein the clamp assembly 102 is mounted on the support base 101, and the support base 101 is used to slide on a steel beam 103. The clamp assembly 102 includes a locking member 105 and two symmetrically arranged clamp bodies 104, one clamp body 104 being connected to the support base 101, and an installation area for placing pipes being formed between the two clamp bodies 104; the two clamp bodies 104 are detachably connected to each other through the locking member 105.

[0027] Each clamp body 104 is equipped with a buffer mechanism 106, and the support base 101 is equipped with a first limiting part 107 for cooperating with the steel beam 103.

[0028] In this embodiment, the clamp body 104 is semi-circular, with one clamp body 104 fixedly connected to the top of the support base 101, and the other clamp body 104 being movable. When the two clamp bodies 104 are closed, they form a circular installation area for wrapping and securing the long-distance oil pipeline. A slide rail 116 is detachably mounted on the steel beam 103 via bolts. The support base 101 is slidably installed within the slide rail 116. During installation, the support base 101 is first slidably installed on the steel beam 103 within the slide rail 116, and then the long-distance oil pipeline is placed between the two clamp bodies 104. Within the installation area, the two clamp bodies 104 are locked by the locking member 105, so that the buffer mechanism 106 fits tightly against the outer wall of the pipe. When the pipe vibrates during operation, the vibration energy is transmitted to the buffer mechanism 106. The buffer mechanism 106 consumes energy through deformation, reduces the vibration amplitude, and avoids resonance amplification. When the pipe expands or contracts axially due to temperature changes, the pipe drives the clamp assembly 102 and the support seat 101 to slide synchronously along the slide rail 116, realizing adaptive adjustment of axial displacement. The first limiting part 107 on the support seat 101 ensures that the sliding is within a safe range and prevents excessive pipe displacement.

[0029] In some embodiments, the buffer mechanism 106 includes a buffer pad 108 and a buffer block 109. The buffer pad 108 is installed inside the clamp body 104. A groove 110 is provided on the buffer pad 108. The buffer block 109 is slidably installed in the groove 110. An elastic element 111 is installed in the groove 110. The buffer block 109 is connected to the buffer pad 108 through the elastic element 111. In this embodiment, both the buffer pad 108 and the buffer block 109 are made of rubber material. The buffer pad 108 can absorb low-frequency, small-amplitude vibrations transmitted by the pipeline through its own elastic deformation, reducing the direct transmission of vibration to the clamp body 104 and the support seat 101, thus playing a preliminary buffering role. Furthermore, the buffer pad 108 can prevent scratches or corrosion caused by vibration friction due to direct rigid contact between the clamp body 104 and the outer wall of the pipeline. In this embodiment, there are several grooves 110, which are evenly spaced along the clamp body 104, and each groove 110 is equipped with the elastic element. The buffer block 109 and the buffer pad 108 are used to directly transmit the pipe vibration to the elastic element 111 through rigid contact. When the pipe vibration pushes the buffer block 109 to slide along the groove 110, the elastic element 111 is compressed or stretched, converting the kinetic energy of the vibration into elastic potential energy, thereby avoiding resonance between the pipe and the clamp body 104 and the support seat 101. The pipe vibration is first transmitted to the elastic element 111 through the buffer block 109. The elastic element 111 efficiently consumes the main vibration energy through deformation. The remaining low-frequency vibration is further absorbed and isolated by the buffer pad 108, preventing it from being transmitted to the clamp and the support seat 101.

[0030] In some embodiments, the clamp body 104 is provided with a guide groove 112, and a guide block 113 is fixedly connected to the buffer pad 108. The buffer pad 108 is slidably connected to the guide groove 112 via the guide block 113. When the pipeline vibrates, in addition to radial vibration, there will also be small axial vibrations, such as axial pulsations caused by the turbulent flow of the medium impacting the inner wall of the pipeline. By allowing the buffer pad 108 to slide synchronously with the small axial vibration of the pipeline via the guide block 113 and the guide groove 112, the buffer pad 108 can slide synchronously with the small axial vibration of the pipeline, keeping the buffer pad 108 in close contact with the pipeline and avoiding damage to the buffer pad 108 and the buffer block 109 by shear stress. The sliding connection between the support base 101 and the steel beam 103 can achieve adaptive adjustment of a large axial displacement of 5-50mm; the sliding of the buffer pad 108 along the guide groove 112 can ensure that the buffer pad 108 can slide synchronously with the high-frequency small-amplitude vibration of the pipeline with a small axial displacement of 3-5mm.

[0031] In some embodiments, a second limiting portion 114 is symmetrically connected to the buffer pad 108. The second limiting portion 114 on the buffer pad 108 can ensure that the buffer pad 108 slides within a safe range and prevent the buffer pad 108 from separating from the clamp body 104.

[0032] In some embodiments, there are two clamp assemblies 102, which are symmetrically mounted on the support base 101. By providing two clamp assemblies 102, the radial load on the pipeline can be evenly distributed, avoiding local stress concentration in a single clamp assembly 102 that could lead to deformation of the clamp body 104 or loosening of the locking element 105.

[0033] In some embodiments, the clamp body 104 is symmetrically connected with connecting ears 115, and the locking member 105 is threadedly connected to the connecting ears 115. The two connecting ears 115 are detachably connected through the locking member 105. In this embodiment, the locking member 105 is a fixing bolt for connecting the corresponding connecting ears 115 on the two clamp bodies 104. The connecting ears 115 symmetrically arranged at both ends of the same clamp body 104 can ensure that the tightening force of the locking member 105 is evenly transmitted along the circumference of the clamp body 104, avoiding uneven contact between the clamp and the outer wall of the pipe due to force misalignment. Furthermore, by adjusting the tightening degree of the locking member 105, the size of the installation area formed between the two clamp bodies 104 can be finely adjusted, improving versatility.

[0034] In some embodiments, the connecting ear 115 is tilted. During the installation of the clamp assembly 102, in a confined space, vertical operation requires a larger tool swing radius; by tilting the connecting ear 115, the operating direction of the locking member 105 can be shifted outward, forming a certain angle with the clamp body 104, allowing the tool to cooperate more smoothly with the locking member 105 and reducing operational jamming caused by space constraints.

[0035] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
