Description

Technical Field

[0001] This utility model pertains to support devices, and specifically relates to an adaptive adjustment support for fluid pipelines. Background Technology

[0002] Ground pipelines can be used to transport refined oil products such as aviation kerosene, and fluid media such as water. For example, in industrial plants, ground pipelines can be used to transport various liquid refined oil products or chemical raw materials required for industrial production. In some construction sites, ground pipelines can also be temporarily laid for water supply and drainage. The pipeline support system is a key component in ensuring the safe and stable operation of pipelines. Especially in outdoor environments, pipeline supports need to withstand various external factors such as ground frost heave, vibration, temperature changes, and corrosion. Therefore, the stability and durability of their structure are crucial. However, some existing pipeline support devices still have some drawbacks, such as those described in public number CN 222513781. A type of pipe positioning bracket for water supply and drainage engineering, in northern regions, experiences significant vertical displacement due to frost heave on the supported ground during long-term use. This can cause excessive upward force on the pipes in the grooved support area, leading to damage to the supported pipelines or downward sag, leaving the pipelines unsupported. The bracket lacks a design to provide cushioning, which can easily cause pipe breakage if not detected promptly, resulting in environmental pollution, safety accidents, and economic losses. Furthermore, the structural design cannot determine whether the pipeline is deformed and address the issue in a timely manner, thus reducing the pipeline's service life. Summary of the Invention

[0003] This invention provides an adaptive regulating support for fluid pipelines to address the shortcomings of existing technologies.

[0004] This utility model discloses an adaptive adjusting support for fluid pipelines, comprising a base, with support rods fixed at each of the four corners of the base, and a support plate fixed between the upper ends of the four support rods by nuts. A through hole is provided at the center of the support plate, and a protective cover I is provided on the through hole and fixed to it. A hydraulic jack is fixed at the center of the base, and the ejector screw of the hydraulic jack passes through the through hole and is placed inside the protective cover I. A working platform is fixed at the end of the ejector screw, a spring is mounted on the working platform, a support column is mounted on the upper end of the spring, and an arc-shaped support frame is fixed at the top of the support column.

[0005] As a further improvement of this utility model, a long strip-shaped observation window I is provided on one end face of the protective cover I, and a scale I is provided on one side of the observation window I.

[0006] As a further improvement of this utility model, a rubber pad is provided on the inner side of the support frame.

[0007] As a further improvement of this utility model, an installation groove is fixed at the bottom end of the support frame to cooperate with the upper end of the support column.

[0008] As a further improvement of this utility model, spring limiting grooves are provided on both the working platform and the support column.

[0009] As a further improvement of this utility model, the protective cover I is cylindrical, and its inner diameter is slightly larger than the diameter of the support column.

[0010] As a further improvement of this utility model, a protective cover II is provided on the outer circumference of the adjusting support, and a long strip-shaped observation window II is provided on one end face of the protective cover II, corresponding to the observation window I, and a scale II is provided on one side of the observation window II.

[0011] This utility model features an adaptive adjustable support for fluid pipelines. Its structure is rationally designed, with support rods fixed at all four corners. One model is suitable for different heights. When the supported ground bulges upwards or sinks downwards due to frost heave, the springs act as a buffer, preventing the support height from rising or falling, which could cause the pipeline to deform and break. The observation window allows workers to easily monitor whether the lower end of the support column is within a safe range. If the lower end is outside the safe range, it indicates that the pipeline deformation exceeds the safe limit, requiring timely adjustment of the support height using a hydraulic jack to change the deformation range, increase pipeline lifespan, reduce costs, and decrease the frequency of support adjustments.

[0016] This utility model discloses an adaptive adjustable support for fluid pipelines, comprising a base 1, with support rods 2 fixed at each of the four corners of the base 1. A support plate 3 is fixed between the upper ends of the four support rods 2 by nuts 18. The height of the support plate 3 can be adjusted by the nuts to adapt to the pipeline height. A through hole 4 is provided at the center of the support plate 3, and a protective cover I9 is ​​provided on the through hole 4 and fixed to it. A hydraulic jack 5 is fixed at the center of the base 1. The ejector screw 16 of the hydraulic jack 5 passes through the through hole 4 and is placed inside the protective cover I9. A working platform 17 is fixed at the end of the ejector screw 16. A spring 6 is mounted on the working platform 17, and a support column 7 is mounted on the upper end of the spring 6. Spring limiting grooves are provided at the upper end of the working platform 17 and the lower end of the support column 7. The upper and lower ends of the spring 6 are respectively placed in the corresponding spring limiting grooves to fix and limit the spring 6, preventing the spring 6 from shifting or falling. The spring 6 can be freely replaced according to different site conditions. An arc-shaped support frame 8 is fixed at the top of the support column 7. A rubber pad 15 is provided on the inner side of the support frame 8. The rubber pad 15 can effectively protect the pipe and prevent wear or damage caused by contact between the pipe and the support. An installation groove 18 is fixed at the bottom of the support frame 8. The upper end of the support column 7 is placed in the installation groove 18 and fixedly connected to it.

[0017] The protective cover I9 is ​​cylindrical, with its inner diameter slightly larger than the diameter of the support column 7, and the diameter of the support column 7 slightly larger than the outer diameter of the spring 6, so that the spring 6 and the support column 7 can move up and down within the protective cover I9 without shifting. A long strip-shaped observation window I10 is provided on one end face of the protective cover I9, and a scale I11 is provided on one side of the observation window I10. The position of the bottom end of the support column 7 can be observed through the observation window I10, and the scale I11 can be used to determine whether the position of the bottom end of the support column 7 is within a safe range.

[0018] To ensure the safety of the entire device, a protective cover II12 is installed around the outer circumference of the adjusting support. A long, narrow observation window II13, corresponding to observation window I10, is located on one end face of the protective cover II12. A scale II14 is also provided on one side of observation window II13. The protective cover II12 protects the entire adjusting support. The position of the bottom of the support column 7 can be seen through observation windows II13 and I10, and the scale II14 indicates whether the position of the bottom of the support column 7 is within the normal range. For easier observation, a pointer is installed at the bottom of the support column 7, positioned within observation windows II13 and I10, and can be moved up and down to read the bearing capacity of the support. The values ​​on scales I11 and II14 correspond, increasing sequentially from top to bottom, such as 0, 1, 2, 3, 4… and the unit is Newtons (N).

[0019] In use, firstly, select a matching spring 6 based on the pipe diameter, length, transported medium, and the material and model of the valves used in the supported pipeline. Then, place both ends of the spring 6 into the spring limiting grooves at the upper end of the working platform 17 and the lower end of the support column 7, respectively, to fix and limit the position of the spring 6. Next, adjust the overall height of the pipeline support using the nut 18 according to the pipeline height to complete the pipeline adjustment. Then, place the device under the pipeline that needs support. Then, determine the spring force range, such as 1~3N, based on factors such as the pressure-bearing capacity of the supported pipeline. Use the hydraulic jack 5 to adjust the height of the support frame 8 so that it fits snugly against the pipeline, ensuring that the lower end of the support column 7 is within a reasonable and safe range of 1~3N on the scale. After the device has been in use for a period of time, staff can periodically observe through observation windows II13 and I10 whether the position of the bottom of the support column 7 is within the 1-3N safe range. When the position of the bottom of the support column 7 drops and falls above the 3N mark, exceeding the safe range, it can be determined that the pipeline is subjected to excessive external force due to ground protrusion or other reasons, which may easily cause the pipeline to break. At this time, staff can release the pressure of the hydraulic jack 5 and readjust the ejector screw 16 to raise the bottom of the support column 7 to within the 1-3N mark. Conversely, when the position of the bottom of the support column 7 rises and falls below the 1N mark, exceeding the safe range, it can be determined that the pipeline is without external support due to ground subsidence or other reasons, which may easily cause the pipeline to break. At this time, staff can release the pressure of the hydraulic jack 5 and readjust the ejector screw 16 to adjust the bottom of the support column 7 to within the 1-3N mark. It can be seen that by using the hydraulic jack 5, the height of the support frame 8 can be adjusted in a timely manner, restoring the pipeline to its optimal state and effectively increasing the service life of the pipeline.
