Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas transmission pipelines, in particular to a safety pipe clamp for transmission pipelines. Background Art

[0002] Due to the unstable fluidity of natural gas transported by pipelines, the pipelines will vibrate to varying degrees during gas transmission. The process pipelines of the stations and valve rooms under the jurisdiction of the gas unit are fixed pipelines on the ground. In order to reduce the vibration of the pipelines during gas transmission and prevent the central axis of the pipeline from shifting, it is necessary to install a U-shaped pipe clamp directly clamped on the top of the pipeline, and the bottom of the pipe clamp is directly fixedly connected to the foundation pier. Affected by the flood season and the thawing of the land in spring, the foundation pier part of the pipe clamps in the station and valve room may settle. Since the pipeline pipe clamp is directly clamped on the top of the pipeline, the lower part of the pipeline pipe clamp is fixedly connected to the foundation pier. Once the foundation pier supporting the pipe clamp settles, the pipeline and the foundation pier will settle together or the pipeline will lack support, which will cause the pipeline to settle. There will also be leakage in the flanges, pipe fittings, and welds connected to the pipeline, which is not conducive to the safe and smooth operation of the pipeline. Utility Model Content

[0003] The purpose of the utility model is to overcome the problem in the prior art that when the foundation pier settles, the pipeline lacks support and protection, resulting in pipeline settlement, and to provide a safety pipe clamp for a conveying pipeline. The safety pipe clamp for the conveying pipeline has the function of well fixing the pipeline, reducing the vibration and deviation of the conveying pipeline, and effectively supporting and protecting the pipeline to prevent the pipeline from settling and causing safety accidents.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a safety pipe clamp for a conveying pipeline, which is applied to the pipeline. The pipe clamp includes an outer clamp wrapping the pipeline and a support platform abutting against the bottom of the pipeline. The outer clamp is a U-shaped structure. The outer clamp is detachably connected to a foundation pier. The support platform is placed above the foundation pier. The support platform includes a fixing mechanism and a lifting and adjusting mechanism movably connected to the fixing mechanism. The lifting and adjusting mechanism is placed on the foundation pier to enable the relative distance between the fixing mechanism and the pipeline to be adjusted.

[0005] During the transportation process, there are pipeline sections above the ground, such as stations, valve rooms, etc., and long-distance pipelines are buried underground. The pipeline safety pipe clamp of this application is mainly used for the protection and support of pipeline sections above the ground, such as pipelines in stations, valve rooms, etc.

[0006] The outer clamp and support platform of the safety pipe clamp wrap the pipeline in all directions. The support platform supports the pipeline, and the outer clamp protects and supports the pipeline. The U-shaped structure of the outer clamp is set to match the shape of the pipeline, which can better wrap the pipeline, and the lower part can also be detachably connected to the foundation pier. The support platform is inside the outer clamp and is also below the pipeline. The support platform has a fixing mechanism and a lifting and adjusting mechanism. Due to the setting of the fixing mechanism and the lifting and adjusting mechanism, the fixing mechanism is set above the lifting and adjusting mechanism, so that the fixing mechanism can be adjusted by the lifting and adjusting mechanism to achieve lifting and lowering, thereby achieving the adjustment of the relative distance between the fixing mechanism and the pipeline. When facing the settlement of the foundation pier, the support platform will be separated from the lower part of the pipeline as the foundation pier descends because it is placed on the foundation pier. At this time, the lifting and adjusting mechanism can be adjusted to raise the fixing mechanism to the position of abutting the pipeline, so that the support platform can continue to support the pipeline. Thereby effectively solving the problem that the pipeline will settle with the settlement of the foundation pier.

[0007] Preferably, the fixing mechanism comprises an arc-shaped support plate abutting against the pipeline, and a lifting plate movably connected to the lifting and adjusting mechanism, and the lifting plate and the arc-shaped support plate are fixedly connected via support ribs.

[0008] Among them, the fixing mechanism includes an arc-shaped support plate and a lifting plate, and the arc-shaped support plate and the lifting plate are fixedly connected by support ribs, that is, the arc-shaped support plate, the support ribs and the lifting plate are all fixedly connected. The arc-shaped support plate is provided to match the external structure of the pipeline. The lifting plate is movably connected to the lifting adjustment mechanism to facilitate the adjustment of the height of the lifting plate in the vertical direction, thereby realizing the lifting and lowering of the entire fixing mechanism. When the foundation pier sinks slightly, the fixing mechanism will separate from the pipeline as the support platform descends. The height of the lifting plate is adjusted by the lifting adjustment mechanism, and the fixing mechanism is again abutted against the pipeline to achieve re-support of the pipeline.

[0009] Preferably, the lifting plates are provided in two groups, and the supporting ribs are also provided in two groups.

[0010] The lifting plate can be an integral structure or a split structure. Arranging the lifting plate into two groups is a preferred embodiment, which can save materials and provide a larger operating space for adjusting the lifting adjustment mechanism. In order to match the structure of the lifting plate, when the lifting plate is a split structure, the support rib is also a split structure, so that the structure of the fixing mechanism is more compact.

[0011] Preferably, the lifting and lowering adjustment mechanism is configured as a bolt structure, including a first bolt and an upper nut and a lower nut cooperatively connected to the first bolt, and a nut is disposed at the bottom of the first bolt.

[0012] The lifting and lowering adjustment mechanism is set as a bolt structure, which is relatively conventional, simple in structure, flexible in operation, and has a lower cost. The nut at the bottom of the bolt structure is directly placed on the foundation pier, and the first bolt is provided with an upper and lower nut, and the height of the structure between the upper and lower nuts can be adjusted by adjusting the positions of the upper and lower nuts.

[0013] Preferably, a first threaded through hole matched with the first bolt is provided on the lifting plate, so that after the first bolt passes through the first threaded through hole, the upper nut is installed above the lifting plate, and the lower nut is installed below the lifting plate.

[0014] In order to better realize the connection between the lifting plate and the lifting adjustment mechanism, a first threaded through hole cooperating with the first bolt is arranged on the lifting plate, so that the first bolt can pass through the lifting plate, and the lifting plate is arranged between the upper and lower nuts. The height of the lifting plate can be adjusted by adjusting the position of the upper and lower nuts, and the operation is flexible and convenient.

[0015] Preferably, four or more first threaded through holes are provided and symmetrically distributed on the lifting plate, and the number of the first bolts matches the number of the first threaded through holes.

[0016] The lifting plate can be provided with four or more first threaded through holes, which are symmetrically distributed on the front and rear parts of the lifting plate with the support rib as the symmetry axis, and the number of the first bolts is the same as the number of the first threaded through holes, so that the lifting and adjusting mechanism can stably support the fixing mechanism, thereby realizing the support platform for the pipeline.

[0017] Preferably, the support platform further comprises a bottom plate arranged at the bottom and abutting against the lifting and adjusting mechanism, and the bottom plate is placed above the foundation pier to support the lifting and adjusting mechanism.

[0018] In order to evenly distribute the force applied by the pipeline to the support platform to the foundation pier, a base plate is provided at the bottom of the support platform. The base plate is placed on the foundation pier, so that the force area transmitted by the pipeline to the foundation pier through the support platform is increased, the pressure applied by the pipeline to the foundation pier is reduced, and the surface of the foundation pier and the bottom surface of the support platform can be better protected.

[0019] Preferably, the outer clamp comprises an outer clamp body of a U-shaped structure and reinforcing ribs arranged on both sides of the outer clamp body.

[0020] The provision of the reinforcing ribs can increase the load-bearing capacity of the outer clamp body and extend the service life of the outer clamp.

[0021] Preferably, a second bolt is pre-embedded in the foundation pier, and the outer clamp body is provided with a second threaded through hole that is threadably matched with the second bolt.

[0022] In order to improve the connection stability between the outer clamp and the foundation pier, a second bolt is pre-buried in the foundation pier, and a second threaded through hole is set in the connection area between the outer clamp body and the foundation pier to bolt the outer clamp to the foundation pier. When the foundation pier encounters settlement, the nut on the second bolt can be adjusted to reduce the extrusion between the outer clamp and the pipeline.

[0023] Preferably, the outer clamp abuts against the supporting platform and the pipeline.

[0024] The connection between the pipeline, the outer clamp and the supporting platform is a hard connection. In order to alleviate the physical damage caused by pipeline vibration, flexible materials are wrapped on the outside of the pipeline to better protect the pipeline. When the foundation pier settles, some buffering can be provided before adjusting the connecting bolts between the outer clamp and the foundation pier.

[0025] Through the above technical solution, the beneficial effects of using the safety pipe clamp of the conveying pipeline of the present application are as follows:

[0026] First, the safety pipe clamp can stably fix the pipeline, reduce pipeline vibration and deviation, and better protect the safe operation of the pipeline.

[0027] Second, safety pipe clamps can effectively support pipelines.

[0028] Third, it can effectively prevent the pipeline from settling. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0036] In the present utility model, unless otherwise specified, directional words such as "up, down, left, right, inside, outside, far, near, front" generally refer to the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present utility model and simplifying the description, and therefore cannot be understood as limitations on the present utility model.

[0037] like Figure 1 A safety pipe clamp for a conveying pipeline is shown, which is applied to a pipeline 2. The pipe clamp 1 includes an outer clamp 11 that wraps the pipeline 2, and a support platform 12 that abuts against the bottom of the pipeline 2. The outer clamp 11 is a U-shaped structure. The outer clamp 11 is detachably connected to the foundation pier 3. The support platform 12 is placed above the foundation pier 3. The support platform 12 includes a fixing mechanism 13 and a lifting and adjusting mechanism 14 that is movably connected to the fixing mechanism 13. The lifting and adjusting mechanism 14 is placed on the foundation pier 3 to enable the relative distance between the fixing mechanism 13 and the pipeline 2 to be adjusted.

[0038] During the transportation process, the pipeline 2 has pipeline sections above the ground, such as stations, valve chambers, etc., and the long-distance pipelines are buried underground. The pipeline safety pipe clamp 1 of the present application is mainly used to protect and support the pipeline sections above the ground, such as the pipelines 2 of stations, valve chambers, etc.

[0039] The outer clamp 11 and the support platform 12 of the safety pipe clamp 1 wrap the pipe 2 in all directions. The support platform 12 supports the pipe 2, and the outer clamp 11 has the dual functions of protecting and supporting the pipe 2. The inverted U-shaped structure of the outer clamp 11 is designed to match the columnar structure of the pipe 2, so that the pipe 2 can be better wrapped. Figure 1 As shown, the outer clamp 11 can wrap the upper part of the pipe 2. At the same time, the lower part can also be detachably connected to the foundation pier 3, such as Figure 1 shown.

[0040] The support platform 12 is located inside the outer clamp 11 and below the pipe 2, that is, the pipe 2 is supported below by the support platform 12, and the outer clamp 11 is wrapped around the pipe 2 and the outside of the support platform 12. Figure 1 As shown, the outer clamp 11 and the support platform 12 are both arranged on the upper surface of the foundation pier 3 , but the outer clamp 11 is connected to the foundation pier 3 , and the support platform 12 is only placed on the foundation pier 3 .

[0041] The supporting platform 12 is composed of a fixing mechanism 13 and a lifting and adjusting mechanism 14, which are movably connected. Figure 4As shown, due to the setting of the fixing mechanism 13 and the lifting and adjusting mechanism 14, and the fixing mechanism 13 is set above the lifting and adjusting mechanism 14, the fixing mechanism 13 can be lifted and lowered by adjusting the lifting and adjusting mechanism 14, thereby adjusting the relative distance between the fixing mechanism 13 and the pipeline 2. When the foundation pier 3 sinks, the support platform 12 will sink with the sinking of the foundation pier 3 due to being placed on the foundation pier 3, and the support platform 12 will be separated from the lower part of the pipeline 2. At this time, the height of the fixing mechanism 13 can be raised by adjusting the lifting and adjusting mechanism 14 until it abuts against the pipeline 2, so that the support platform 12 can continue to support the pipeline 2. Thereby effectively solving the problem that the pipeline 2 will sink with the sinking of the foundation pier 3.

[0042] Furthermore, the fixing mechanism 13 includes an arc-shaped support plate 121 abutting against the pipeline 2 , and a lifting plate 123 movably connected to the lifting adjustment mechanism 14 , and the lifting plate 123 is fixedly connected to the arc-shaped support plate 121 via a support rib 122 .

[0043] The fixing mechanism 13 includes an arc-shaped support plate 121 and a lifting plate 123, and the arc-shaped support plate 121 and the lifting plate 123 are fixedly connected by the support ribs 122, that is, the arc-shaped support plate 121, the support ribs 122 and the lifting plate 123 are all fixedly connected, and the fixed connection can be welded or integrally formed, such as Figure 4 As shown. The arc-shaped support plate 121 is provided to match the external structure of the pipeline 2. The support plate is provided in an arc shape to better support the pipeline 2. The lifting plate 123 is movably connected to the lifting adjustment mechanism 14, which is convenient for adjusting the height of the lifting plate 123 in the vertical direction, thereby realizing the lifting and lowering of the entire fixing mechanism 13. When the foundation pier 3 sinks slightly, the fixing mechanism 13 will separate from the pipeline 2 as the support platform 12 descends. The height of the lifting plate 123 is adjusted by the lifting adjustment mechanism 14, and the fixing mechanism 13 is again abutted against the pipeline 2 to achieve the re-support of the pipeline 2.

[0044] Furthermore, the lifting plates 123 are provided in two groups, and the supporting ribs 122 are also provided in two groups.

[0045] The lifting plate 123 can be an integral structure or a split structure. It is a preferred embodiment to set the lifting plate 123 in two groups. Figure 4 As shown, it is possible to save materials and provide a larger operating space when adjusting the lifting adjustment mechanism 14. In order to match the structure of the lifting plate 123, when the lifting plate 123 is a split structure, the support rib 122 is also a split structure, such as Figure 4 As shown, the overall structure of the fixing mechanism 13 is made more compact.

[0046] Furthermore, the lifting and lowering adjustment mechanism 14 is configured as a bolt structure, including a first bolt 125 and an upper nut 127 and a lower nut 126 that are matched and connected to the first bolt 125 . A nut 128 is disposed at the bottom of the first bolt 125 .

[0047] The lifting adjustment mechanism 14 is set as a bolt structure, which is relatively conventional, simple in structure, flexible in operation, and has a lower cost. The nut 128 at the bottom of the bolt structure is directly placed on the foundation pier 3, and the first bolt 125 is provided with an upper and lower nut, and the height of the structure between the upper and lower nuts can be adjusted by adjusting the positions of the upper and lower nuts.

[0048] Furthermore, a first threaded through hole 129 cooperating with the first bolt 125 is provided on the lifting plate 123 , so that after the first bolt 125 passes through the first threaded through hole 129 , the upper nut 127 is installed above the lifting plate 123 , and the lower nut 126 is installed below the lifting plate 123 .

[0049] In order to better realize the connection between the lifting plate 123 and the lifting adjustment mechanism 14, a first threaded through hole 129 cooperating with the first bolt 125 is provided on the lifting plate 123, so that the first bolt 125 can pass through the lifting plate 123 through the first threaded through hole 129, and the lifting plate 123 is set between the upper nut 127 and the lower nut 126. The height of the lifting plate 123 can be adjusted by adjusting the position of the upper and lower nuts, and the operation is flexible and convenient.

[0050] Furthermore, four or more first threaded through holes 129 are provided and symmetrically distributed on the lifting plate 123 , and the number of the first bolts 125 matches the number of the first threaded through holes 129 .

[0051] The first threaded through holes 129 on the lifting plate 123 may be provided with four or more, and symmetrically distributed at the front and rear parts of the lifting plate 123 with the support rib 122 as the symmetry axis, such as Figure 4 As shown, at the same time, the number of the first bolts 125 is the same as the number of the first threaded through holes 129. The lifting and lowering adjustment mechanism 14 can stably support the fixing mechanism 13, thereby achieving the support of the supporting platform 12 to the pipeline 2.

[0052] Furthermore, the supporting platform 12 further includes a bottom plate 124 disposed at the bottom and abutting against the lifting and adjusting mechanism 14 . The bottom plate 124 is placed above the foundation pier 3 to support the lifting and adjusting mechanism 14 .

[0053] In order to increase the service life of the support platform 12, a bottom plate 124 can be provided at the bottom of the support platform 12, the bottom plate 124 is placed on the foundation pier 3, and the nut 128 of the lifting and lowering adjustment mechanism 14 is placed on the bottom plate. Figure 1This arrangement evenly distributes the force applied by the pipeline 2 to the support platform 12 to the foundation pier 3, thereby increasing the force bearing area of ​​the pressure transmitted by the pipeline 2 to the foundation pier 3 through the support platform 12, reducing the pressure applied by the pipeline 2 to the foundation pier 3, and better protecting the surface of the foundation pier 3 and the bottom surface of the support platform 12.

[0054] Furthermore, the outer clamp 11 includes an outer clamp body 111 of a U-shaped structure and reinforcing ribs 112 arranged on both sides of the outer clamp body 111 .

[0055] Both sides of the outer clamp 11 are fixedly connected with reinforcing ribs 112 . The provision of the reinforcing ribs 112 can improve the load-bearing capacity of the outer clamp body 111 , thereby extending the service life of the outer clamp 11 .

[0056] Furthermore, the foundation pier 3 is pre-buried with a second bolt 31 , and the outer clamp body 111 is provided with a second threaded through hole 113 threadably matched with the second bolt 31 .

[0057] In order to improve the connection stability between the outer clamp 11 and the foundation pier 3, the second bolt 31 is pre-buried in the foundation pier 3, and a second threaded through hole 113 is provided in the position area corresponding to the foundation pier 3 on the outer clamp body 111, so as to bolt the outer clamp 11 to the foundation pier 3. When the foundation pier 3 encounters settlement, the nut on the second bolt 31 can be adjusted to reduce the extrusion between the outer clamp 11 and the pipe 2.

[0058] Furthermore, the outer clamp 11 abuts against the supporting platform 12 and the pipeline 2 .

[0059] The connection between the pipeline 2, the outer clamp 11 and the supporting platform 12 is a hard connection. In order to alleviate the physical damage caused by the vibration of the pipeline 2 during transportation, a flexible material can be wrapped on the outside of the pipeline 2 to better protect the pipeline 2. When the foundation pier 3 settles, some buffering can be provided before the connecting bolts between the outer clamp 11 and the foundation pier 3 are adjusted.

[0060] It should be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0061] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
