Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary accessories for pressure pipelines, and in particular relates to a detachable sliding pipe support for online pipelines. Background Art

[0002] At present, some pressure pipelines are usually placed directly on concrete piers. Due to rainwater accumulation and thermal expansion and contraction friction, pitting corrosion is prone to occur at the bottom of the pipeline, which affects the quality of the pipeline. During pipeline transportation, there will usually be certain vibrations, or thermal expansion and contraction, which will cause slight relative movement between the pipeline and the pier, resulting in certain sliding friction. Under long-term operation, it is easy to cause pipeline wear and affect the quality of the pipeline. In particular, local corrosion or wear of the contact surface where the pipeline directly contacts the concrete will directly reduce the service life of the pipeline or cause failure. In severe cases, the pipeline needs to be partially replaced. Therefore, it is necessary to install a pipe support structure on the pipeline to support the pipeline and avoid direct contact between the pipeline and the concrete pier to prevent such phenomena from occurring.

[0003] Since some existing pipes without pipe supports are usually placed on concrete pipe piers, it is necessary to excavate the pipe piers under the pipes when installing pipe supports. Due to the quality of the pipe piers, the excavation height is not easy to control, and the height of the space under the pipes for installing pipe supports is often too high or too low, so the pipe supports need to be able to make certain adjustments according to the actual height; in addition, the support plate part of some existing pipe supports connected to the pipes is supported by a flat plate, resulting in no restraint on both sides of the pipes. The vibration generated during the operation of the pipes will cause the pipes to sway slightly left and right, resulting in relative sliding between the flat support plate. Under long-term operation, it is easy to cause wear of the pipes, affecting the quality of the pipes. In addition, the support plate of the pipe support will also show certain wear, thereby reducing the service life of the pipe support; in addition, regular inspection and maintenance work is required during the operation of the pipelines. The support plates of some existing pipe supports are directly welded to the pipes, and the online pipes and pipe supports cannot be directly disassembled and assembled. Hot cutting (special operations) is required to disassemble and assemble the pipe supports, which brings great risks to the safe operation of the pressure pipeline. Utility Model Content

[0004] In view of this, in order to solve the above problems, the utility model provides a detachable sliding pipe support for an online pipeline.

[0005] A detachable sliding pipe support for an online pipeline comprises a support plate, the support plate contacts and supports the bottom of the pipeline, the contact surface between the support plate and the pipeline is an arc-shaped surface, the movable component comprises a movable frame, a vertical plate and a bottom plate, the vertical plates are mounted on both sides of the bottom plate and are detachably connected to the bottom plate, the top of the movable frame is connected to the support plate, the two sides of the movable frame are slidably connected to the vertical plates, a slide plate is provided on the lower side of the bottom plate, the slide plate is fixedly connected to the bottom plate, and a plurality of sliding sheets are embedded at the bottom of the slide plate.

[0006] In the above technical solution, the side of the support plate in contact with the pipeline is an arc surface, which is directly in contact with the outer side of the pipeline. The two sides of the arc structure can provide a certain opposing support force to the pipeline, so that the support plate does not need to be fixedly connected to the pipeline, and the pipeline can be kept stable and relative sliding can be reduced, thereby reducing the friction between the pipeline and the support plate, reducing wear, protecting the pipeline structure, and also extending the service life of the support plate; a movable component is provided at the bottom of the support plate, wherein two vertical plates are provided, and the two vertical plates are detachably installed on both sides of the bottom plate, the two vertical plates are parallel to each other and perpendicular to the bottom plate, the movable frame is located between the two vertical plates, and the two sides of the movable frame are respectively slidably connected with the two vertical plates, so that the height of the support plate can be adjusted by sliding the movable frame; the slide plate is located below the bottom plate and fixedly connected to the bottom plate, the slide plate is made of a material with a small friction coefficient, and a plurality of sliding sheets are provided on the bottom surface of the slide plate, which effectively improves the sliding performance of the slide plate, and when installing the pipe support, the pipe support can be slid as a whole to a suitable position below the pipeline by sliding the slide plate, making the installation of the pipe support more convenient and quick.

[0007] Therefore, the present application provides opposite supporting forces to the pipeline from both sides of the pipeline by setting an arc-shaped support plate, so that the pipeline can be directly placed on the support plate and remain stable, thereby reducing the relative movement of the pipeline and avoiding wear of the pipeline. At the same time, there is no fixed connection between the support plate and the pipeline, and the vertical plate and the bottom plate are detachably connected. When the pipeline is inspected and maintained in the future, the pipes on both sides of the pipe support can be directly lifted up a short distance using a jack or other device to remove the pipe support and complete the removal. There is no need for hot cutting, thus simplifying the removal work. In addition, if there is no relevant device for lifting the pipeline, the vertical plate can also be removed from the bottom plate to , lowering the height of the pipe support, thereby taking the pipe support out from the bottom of the pipeline, making it convenient for subsequent maintenance work on the pipeline; the present application is provided with a movable component, and the height of the support plate can be adjusted by sliding between the movable frame and the vertical plate to ensure that the support plate is in contact with the pipeline, and it is flexibly adapted to installation environments at various heights and has good practicality; the present application is provided with a slide plate, and a plurality of sliding sheets are provided at the bottom of the slide plate, which effectively improves the sliding performance of the slide plate.

One end of the support plate is vertically installed on the movable plate, and the other end is connected to the bottom of the support plate. The left and right sides of the movable plate are respectively slidably connected to the vertical plates on both sides. The movable plate can slide up and down along the vertical plates, thereby driving the support plate and the support plate to slide up and down, thereby realizing the height adjustment of the pipe support.

[0010] Optionally, in a possible implementation manner, a gap is left between the support plate and the vertical plate.

[0011] In the above technical solution, after the support plate is adjusted to an appropriate height, in order to prevent the movable parts from continuing to move and causing the height of the support plate to change, the movable frame and the vertical plate are fixed by welding, and the gap left between the support plate and the vertical plate is used to fill the solder, thereby strengthening the fixing effect of the movable frame and the vertical plate after welding and ensuring a stable fixation.

[0035] Please refer to Figures 1 to 4 In a preferred embodiment, a detachable sliding pipe support for an online pipeline is provided, which includes a support plate 1, the support plate 1 contacts and supports the bottom of the pipeline 7, the contact surface between the support plate 1 and the pipeline 7 is an arc-shaped surface, a movable component is connected to the bottom of the support plate 1, and the movable component includes a movable frame 2, a vertical plate 3 and a bottom plate 4, the vertical plate 3 is installed on both sides of the bottom plate 4 and is detachably connected to the bottom plate 4, the top of the movable frame 2 is connected to the support plate 1, and the two sides of the movable frame 2 are slidably connected to the vertical plate 3, a slide plate 5 is provided on the lower side of the bottom plate 4, the slide plate 5 is fixedly connected to the bottom plate 4, and a plurality of sliding sheets 51 are embedded at the bottom of the slide plate 5.

[0036] In this embodiment, the top surface of the support plate 1 is an arc-shaped surface, which is directly in contact with the outer side of the pipe 7. The two sides of the arc-shaped structure can provide a certain opposite supporting force to the pipe 7, so that the support plate 1 does not need to be fixedly connected to the pipe 7, so that the pipe 7 can be kept stable and the relative sliding can be reduced, thereby reducing the friction force between the pipe 7 and the support plate 1, reducing wear and tear, protecting the pipe 7 structure, and also extending the service life of the support plate 1; a movable component is provided at the bottom of the support plate 1, specifically, two vertical plates 3 are provided, and the two vertical plates 3 can be detachably installed on both sides of the bottom plate 4, respectively, the two vertical plates 3 are parallel to each other and perpendicular to the bottom plate 4, the movable frame 2 is located between the two vertical plates 3, and The two sides of the movable frame 2 are respectively slidably connected to the two vertical plates 3, so that the height of the support plate 1 can be adjusted by sliding the movable frame 2; the slide plate 5 is located below the bottom plate 4 and is fixedly connected to the bottom plate 4. Preferably, the slide plate 5 is made of polytetrafluoroethylene (PTFE), which has an extremely low friction coefficient, good sliding performance, and is acid-resistant, alkali-resistant, and corrosion-resistant. It can better adapt to the environment in which the pipeline 7 is located. A plurality of sliding sheets 51 are provided on the bottom surface of the slide plate 5 to enhance the sliding performance of the slide plate 5, so that the sliding of the slide plate 5 is smoother. Specifically, when installing the pipe support, the slide plate 5 is slid to move the pipe support as a whole to a suitable position below the pipeline 7, and the installation is more convenient and quick.

[0037] Therefore, the present application provides opposite supporting forces to the pipe 7 from both sides of the pipe 7 by setting an arc-shaped support plate 1, so that the pipe 7 can be directly placed on the support plate 1 and remain stable, thereby reducing the relative movement of the pipe 7 and avoiding wear of the pipe 7. At the same time, there is no fixed connection between the support plate 1 and the pipe 7, and the vertical plate 3 and the bottom plate 4 are detachably connected. When the pipeline is inspected and maintained in the future, the pipes 7 on both sides of the pipe support can be directly lifted up a short distance using a jack or other device to remove the pipe support and complete the removal. There is no need for hot cutting, thereby simplifying the removal work. In addition, if there is no relevant device for lifting the pipe 7, the vertical plate 3 can also be removed from the bottom plate 4 to reduce the wear. The height of the pipe support is low, so that the pipe support can be taken out from the bottom of the pipe 7, which is convenient for subsequent maintenance work on the pipe 7; the present application is provided with a movable component, and the height of the support plate 1 can be adjusted by sliding between the movable frame 2 and the vertical plate 3 to ensure that the support plate 1 is in contact with the pipe 7, and it is flexibly adapted to installation environments at various heights and has good practicality; the present application is provided with a slide plate 5 with good sliding performance, and a plurality of sliding sheets 51 are provided at the bottom of the slide plate 5, which effectively improves the sliding performance of the slide plate 5. When installing the pipe support, the slide plate 5 can be used to drive the pipe support to move as a whole to a suitable position under the pipe 7, so that the positioning work during the installation of the pipe support is faster, and the installation is simpler and faster.

[0038] It should be noted that, in the specific implementation, since a pipe pier 8 is usually provided at the bottom of the pipeline 7, and the pipeline 7 is usually directly placed on the pipe pier 8, the pipe pier 8 at the bottom of the pipeline 7 needs to be partially excavated before the installation of the pipe support, such as Figure 3 As shown, a base plate 9 is then installed at the bottom of the excavated part (the base plate 9 is usually made of steel plate with high strength), and then a lifting device such as a jack is used to lift the pipe 7 for a short distance, and then the pipe support is placed on the steel plate as a whole, and the slide plate 5 at the bottom of the pipe support is used to slide on the base plate 9 to adjust the position of the pipe support. After the pipe support is moved to a suitable position, the pipe 7 is lowered so that the pipe 7 is placed on the support plate 1, and the installation of the pipe support is completed.

[0039] Please refer to Figures 1 to 4 In a non-limiting embodiment of the utility model, the movable frame 2 includes a support plate 21 and a movable plate 22, and the two sides of the movable plate 22 are slidably connected to the vertical plate 3, and the support plate 21 is installed on both sides of the top surface of the movable plate 22.

One end of the support plate 21 is vertically installed on the movable plate 22, and the other end is connected to the bottom of the support plate 1. The left and right sides of the movable plate 22 are respectively slidably connected to the vertical plates 3 on both sides. The movable plate 22 can slide up and down along the vertical plate 3, thereby driving the support plate 21 and the support plate 1 to slide up and down to achieve the height adjustment of the pipe support. Since the space from the pipe to the bottom may be too low or too high after the pipe pier 8 is partially excavated, the height of the pipe support can be adjusted according to the actual situation of the on-site construction through the up and down sliding of the movable plate 22, so as to ensure that the height of the pipe support will not change after the pipe support is installed on the pipeline 7, and the pipe support can be installed without affecting the normal transportation of the pipeline 7 without changing the pipeline 7 body, which is effectively suitable for the installation of the online pipeline 7.

[0040] In some embodiments, a protrusion is provided on the left and right sides of the movable plate 22, and a matching slide groove is provided on the vertical plate 3. The movable plate 22 can slide up and down through the cooperation between the protrusion and the slide groove. In addition to the above-mentioned setting method, other methods can also be used, as long as the movable plate 22 can slide in the vertical direction along the vertical plate 3.

[0044] Please refer to Figure 1 In a non-limiting embodiment of the present invention, the central angle of the arc is less than 180°. In this embodiment, the central angle of the arc of the cross section of the support plate 1 is less than 180°, so that the lateral force in the horizontal direction (i.e. Figure 1 The force in the horizontal left and right directions as shown) can prevent the two sides of the support plate 1 from being subjected to a large reverse force due to the vibration of the pipeline 7, avoid cracks and cracks on the support plate 1 caused by long-term pressure, effectively protect the structure of the support plate 1, and improve practicality; in this embodiment, preferably, the central angle corresponding to the arc is 120°.
