Description

Technical Field

[0001] This invention belongs to the field of petrochemical pipeline technology, specifically relating to a self-resetting shock-absorbing pipe support device for oil pipelines. Background Technology

[0002] Petrochemicals generally refer to the chemical industry that uses petroleum and natural gas as raw materials, playing a vital role in national economic development. Every stage of the petrochemical process—extraction, transportation, refining, and utilization—is crucial, and pipeline transportation, with its advantages of stable, uninterrupted transport, low losses, and low freight costs, has become one of the main methods for transporting oil and natural gas. my country's pipeline transportation network is also growing rapidly and will continue to play an irreplaceable role in the future.

[0003] However, many areas in my country are prone to earthquakes, and these frequent earthquakes can cause irreversible and severe damage to pipe supports, leading to unbalanced stress on the pipeline, severe deformation, media leakage, endangering public safety, and causing property damage. Traditional pipe supports deform severely after earthquakes and are difficult to repair, wasting manpower and resources, and have low practical performance. In view of this, this invention proposes a self-resetting shock-absorbing pipe support device for oil pipelines. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a self-resetting shock-absorbing pipe support device for oil pipelines, which addresses the shortcomings of the prior art. This pipe support device, through a multi-shock-absorbing structure design, can absorb seismic energy after deformation and then restore its initial state through a self-resetting function, greatly improving its efficiency and having good practicality.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a self-resetting shock-absorbing pipe support device for oil pipelines, comprising a pipe support base plate, a support, and several annular fasteners for fixing the oil pipeline. The pipe support base plate is fixed to an external foundation. A guide rail is fixed on the pipe support base plate. The guide rail is parallel to the axis of the several annular fasteners. A slider is installed on the guide rail. The support is fixed on the slider. Several sets of viscoelastic bodies are fixed on the support. Each annular fastener is supported by a set of viscoelastic bodies. A positioning plate is fixed to the bottom of each annular fastener. Each positioning plate is clamped by a set of viscoelastic bodies. The inner wall of each annular fastener is covered with a rubber pad. Several shape memory tension springs are provided between each annular fastener and the pipe support base plate.

[0006] After the pipe support device of this invention is put into use, it fixes the oil pipeline with several annular fasteners. In the event of an earthquake, the support, the oil pipeline, and the several annular fasteners can slide as a whole along the guide rail, that is, the oil pipeline slides relative to the external foundation. The force along the direction of the oil pipeline is consumed by the slider, achieving a shock absorption effect, thereby effectively preventing longitudinal (i.e. axial) tensile cracking damage to the pipe support device due to external forces. The deformation recovery function of the shape memory spring is used to dissipate energy and simultaneously pull the support and the oil pipeline back to their initial positions. Under the earthquake, the relative displacement of the slider and the deformation of the viscoelastic body can be restored to the pre-earthquake state by the shape memory spring, achieving a self-resetting effect and overall stability. Furthermore, the viscoelastic body used to fix the ring fastener can generate shear deformation perpendicular to the direction of the oil pipeline under seismic action. This allows the force perpendicular to the oil pipeline to be consumed through the deformation of the viscoelastic body, further dissipating seismic energy. As a damping mechanism, the viscoelastic body can effectively reduce the vibration of the oil pipeline and protect it. In addition, the rubber pads covering the inner wall of the ring fastener can increase the friction between the ring fastener and the oil pipeline, preventing the oil pipeline from shifting with the ring fastener under internal and external forces. This stabilizes the oil pipeline and provides a good buffering effect, further enhancing the vibration reduction effect of the device and greatly improving the protection of the oil pipeline.

[0007] Preferably, each of the aforementioned ring fasteners includes an upper semi-circular fastener and a lower semi-circular fastener. The upper semi-circular fastener is fastened onto the lower semi-circular fastener. A first connecting plate is fixed to each of the radial ends of the upper semi-circular fastener, and a second connecting plate is fixed to each of the radial ends of the lower semi-circular fastener. Each of the first connecting plates is stacked on a second connecting plate and the two are connected by bolts and nuts. The positioning plate is fixed to the bottom of the lower semi-circular fastener. The top surface of each set of viscoelastic materials is an arc surface, and the bottom of the lower semi-circular fastener contacts the top surface of the set of viscoelastic materials.

[0008] Preferably, each of the aforementioned annular fasteners is connected to the tube support base plate by two shape memory springs. Each shape memory spring has a threaded section at both ends. One threaded section is fixed to a stacked first connecting plate and a second connecting plate by nuts, and the other threaded section is fixed to the tube support base plate by nuts. The threaded sections at both ends of the shape memory springs are fixed with nuts, facilitating adjustment of the spring's elasticity and ensuring its normal operation within its elastic range.

[0009] Preferably, the support includes a steel support base plate, which is fixed to the slider. Several sets of trapezoidal steel plates are vertically welded to the support base plate. Each set of viscoelastic body is fixed to one set of trapezoidal steel plates. A first stiffening plate is welded between each set of trapezoidal steel plates and the support base plate. A second stiffening plate is welded between two adjacent sets of trapezoidal steel plates.

[0010] Preferably, each set of trapezoidal steel plates includes two trapezoidal steel plates arranged facing each other, and each set of viscoelastic bodies includes two viscoelastic bodies arranged facing each other. Each viscoelastic body is fixed on one of the trapezoidal steel plates, and there is a gap between the two viscoelastic bodies. A positioning plate is inserted into the gap, and neither the positioning plate nor the bottom surface of the two viscoelastic bodies contacts the support base plate.

[0011] Preferably, each viscoelastic body is a rubber block. Rubber has stable material properties and significant energy dissipation, ensuring effective energy dissipation during earthquakes.

[0012] Preferably, the tube support base plate is fixed with two guide rails, each guide rail is equipped with a slider, and the support is fixed on the two sliders.

[0013] Preferably, the pipe support base plate has several bolt holes, and the pipe support base plate is fixed to the external foundation by several bolts.

[0014] Compared with the prior art, the present invention has the following advantages: The self-resetting shock-absorbing pipe support device for oil pipelines is simple in structure and easy to process. Through the design of multiple shock-absorbing structures, after the deformation absorbs the seismic energy, the device can restore the initial state through the self-resetting function, which greatly improves the efficiency of use and has good practicality. It can solve the technical problems of traditional pipe support supports being prone to cracking and deformation and unable to reset under seismic action. Attached Figure Description

[0023] To illustrate the present invention more clearly and completely, it will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The scope of application of the present invention is not limited to oil pipelines, but also applicable to other chemical pipelines.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] The embodiment of the self-resetting shock-absorbing pipe support device for oil pipelines, such as Figures 1-6 As shown, the device includes a pipe support base plate 1, a support, and two annular fasteners for fixing the oil pipeline. The pipe support base plate 1 has several bolt holes 11 and is fixed to the external foundation by expansion bolts or high-strength bolts. Two guide rails 2 are fixed to the pipe support base plate 1 by bolts 21. The guide rails 2 are parallel to the axes of the two annular fasteners. A slider 3 is installed on each guide rail 2. The support is fixed on the two sliders 3. Two sets of viscoelastic bodies are fixed on the support. Each annular fastener is supported by a set of viscoelastic bodies. A positioning plate 63 is fixed to the bottom of each annular fastener. Each positioning plate 63 is clamped by a set of viscoelastic bodies. The inner wall of each annular fastener is covered with a rubber pad 64. Two shape memory tension springs 7 are provided between each annular fastener and the pipe support base plate 1.

[0026] In this embodiment, each ring fastener includes an upper semi-circular fastener 61 and a lower semi-circular fastener 62. The upper semi-circular fastener 61 is fastened to the lower semi-circular fastener 62. The radial ends of the upper semi-circular fastener 61 are respectively fixed with a first connecting plate 67, and the radial ends of the lower semi-circular fastener 62 are respectively fixed with a second connecting plate 68. Each first connecting plate 67 is stacked on a second connecting plate 68 and the two are connected by bolts 65 and nuts 66. The bottom of the lower semi-circular fastener 62 is fixed with a positioning plate 63. The top surface of each set of viscoelastic bodies is an arc surface 69, and the bottom of the lower semi-circular fastener 62 is in contact with the top surface of a set of viscoelastic bodies. Each shape memory tension spring 7 has a threaded section 71 processed at both ends. One threaded section 71 is fixed to a stacked first connecting plate 67 and a second connecting plate 68 by a nut, and the other threaded section 71 is fixed to the tube support base plate 1 by a nut.

[0027] In this embodiment, the support includes a steel support base plate 4, which is fixed to the slider 3 by bolts 44. Two sets of trapezoidal steel plates 43 are vertically welded on the support base plate 4. Each set of viscoelastic body is fixed to a set of trapezoidal steel plates 43. A first stiffening plate 41 is welded between each set of trapezoidal steel plates 43 and the support base plate 4. A second stiffening plate 42 is welded between two adjacent sets of trapezoidal steel plates 43. Specifically, each set of trapezoidal steel plates 43 includes two trapezoidal steel plates 43 arranged in opposite directions. Each set of viscoelastic body includes two viscoelastic bodies 5 arranged in opposite directions. Each viscoelastic body 5 is made of rubber block. Each viscoelastic body 5 is fixed on a trapezoidal steel plate 43. There is a gap between the two viscoelastic bodies 5. A positioning plate 63 is inserted into the gap. The bottom surfaces of the positioning plate 63 and the two viscoelastic bodies 5 do not contact the support base plate 4.

[0028] After the aforementioned pipe support device is put into use, the oil pipeline is fixed by two annular fasteners. During an earthquake, the support, oil pipeline, and annular fasteners can slide as a whole along the guide rail 2, that is, the oil pipeline slides relative to the external foundation. The force along the direction of the oil pipeline is dissipated by the slider 3, achieving a shock absorption effect, thereby effectively preventing longitudinal (i.e. axial) tensile cracking damage to the pipe support device due to external forces. The deformation recovery function of the shape memory spring 7 is used to dissipate energy and simultaneously pull the support and oil pipeline back to their initial positions. Under the earthquake, the relative displacement generated by the slider 3 and the deformation generated by the viscoelastic body 5 can be restored to the pre-earthquake state by the shape memory spring 7, achieving a self-resetting effect and overall stability. Furthermore, the viscoelastic body 5 used to fix the annular fastener can generate shear deformation perpendicular to the direction of the oil pipeline under seismic action, thereby dissipating the force perpendicular to the oil pipeline through the deformation of the viscoelastic body 5, further dissipating seismic energy. As a damping mechanism, the viscoelastic body 5 can effectively reduce the vibration of the oil pipeline and protect it. In addition, the rubber pad 64 covering the inner wall of the annular fastener can increase the friction between the annular fastener and the oil pipeline, preventing the oil pipeline from shifting with the annular fastener under the action of internal and external forces, thus stabilizing the oil pipeline and providing a good buffering effect. This further enhances the vibration reduction effect of the device and greatly improves the protection of the oil pipeline.

[0029] This pipe support device, relying on the shock absorption and self-resetting characteristics of its internal structure, effectively ensures overall stability. Under earthquake action, it not only better protects the oil pipeline, but is also not easily damaged itself, exhibiting good durability and effectiveness, and can greatly save economic and labor costs.
