Description

Technical Field

[0001] This utility model relates to the field of natural gas pipeline installation technology, specifically a support frame for a bending joint of a natural gas transportation pipeline. Background Technology

[0002] Natural gas, as a clean and efficient energy source, relies heavily on pipeline systems for long-distance transportation. However, the numerous bends and joints within these pipeline networks represent a critical vulnerability in ensuring transportation safety. These bends must withstand not only the pressure of the natural gas medium within the pipeline but also additional stresses from the external environment. Therefore, specialized support frames are essential for stable support, ensuring the pipeline connections remain airtight, maintain structural integrity, and guarantee long-term operational safety.

[0003] However, existing support frames for bending joints in natural gas transportation pipelines still have significant shortcomings: most existing support frames adopt a fixed integrated structure, lacking a flexible adjustable support mechanism and a highly adaptable clamping structure. This makes it impossible to flexibly adjust the support angle and height according to the actual installation angle of the bending joint and the on-site construction space, resulting in poor installation adaptability of the support frame and insufficient pipeline support stability. This fails to meet the requirements of the bending joint for precise and stable support under different working conditions, which may affect the sealing performance and service life of the pipeline bending joint. Utility Model Content

[0004] To address the problems of existing technologies, this utility model provides a support frame for a bending joint of a natural gas transportation pipeline, comprising: Base; A frame; the lower end of the frame is connected to the top of the base for supporting the component that fixes the folding joint; A support and adjustment assembly; the lower end of the support and adjustment assembly is connected to the top of the frame for supporting the natural gas pipeline; Clamping assembly; the lower end of the clamping assembly is connected to the upper end of the support adjustment assembly, and the upper end of the clamping assembly is connected to the key bend of the gas pipeline; The support adjustment assembly includes: a bearing housing fixedly assembled inside the frame, and a support shaft inserted into the bearing housing; The lower end of the support shaft is fixedly connected to the base, and the support shaft can rotate relative to the frame; A bearing sleeve is also fixedly mounted on the frame, and a support rod is inserted inside the bearing sleeve. The upper end of the support rod passes through the bearing sleeve and is connected to the clamping assembly. The support rod can adjust the support height or horizontal position of the clamping assembly relative to the bearing sleeve.

[0005] Furthermore, the clamping assembly includes: a clamping base and an arc-shaped sleeve; The bottom of the arc-shaped sleeve is fixedly connected to the top of the support rod, and the top of the arc-shaped sleeve is connected to the top of the clamping seat through a connecting frame to form a hinged fit. The two ends of the connecting frame are respectively hinged to the top of the arc-shaped sleeve and the top of the clamping seat through hinge pins.

[0006] Furthermore, a U-shaped seat is installed at the bottom of the clamping seat, and a card seat is fixedly installed at the bottom of the arc-shaped sleeve. A T-bolt is hinged inside the card seat, and a nut sleeve is fitted on the surface of the T-bolt. The T-bolt can be inserted into the slot of the U-shaped seat. By tightening the nut sleeve, the card seat and the U-shaped seat can form a locking fit, thereby fixing the arc-shaped sleeve and the clamping seat to clamp the natural gas pipeline body.

[0007] Furthermore, an elastic buffer layer is fitted to the inner wall of the clamping seat. The elastic buffer layer is made of EPDM rubber and is fixedly connected to the inner wall of the clamping seat by epoxy adhesive.

[0008] Furthermore, the base has symmetrically distributed bolt holes at its bottom end, which are used to insert fixing bolts.

[0009] Furthermore, a limiting pin is installed on the outer wall of the bearing sleeve on one side of the support rod, and the limiting pin is used to limit the rotation range of the support rod relative to the bearing sleeve.

[0010] The beneficial effects of this utility model are: 1. By installing the support shaft inside the bearing housing and fixing the bearing housing to the frame, the support shaft can rotate freely relative to the frame, improving the adjustment flexibility of the support frame and adapting to the installation requirements of natural gas pipelines at different angles and positions. The bottom end of the support shaft is fixedly connected to the base, ensuring the stability of the entire support frame and maintaining structural stability even in complex and changeable installation environments.

[0011] 2. Since the support rod can rotate freely around the frame, and the clamping seat is fixedly connected to the support rod, the natural gas pipeline body is installed inside the clamping seat, allowing the natural gas pipeline body to rotate freely around the base. This significantly reduces the amount of friction on the surface of the heat shrink tubing and extends its service life.

[0012] 3. By placing the natural gas pipeline body inside the clamping seat, using the cooperation of the connecting frame and bearing seat, the arc sleeve is closed, and then the U-shaped seat and the clamping seat are clamped together. Simply rotate the nut sleeve, and with the support of the clamping seat, the U-shaped seat and the clamping seat can be locked together by the cooperation of the nut sleeve and the T-bolt, thus firmly fixing the arc sleeve and the clamping seat, simplifying the installation steps and improving work efficiency.

[0017] In some embodiments, the clamping assembly includes: a clamping base 6 and an arc-shaped sleeve 11; The bottom of the arc-shaped sleeve 11 is fixedly connected to the top of the support rod 9. The top of the arc-shaped sleeve 11 is connected to the top of the clamping seat 6 through the connecting frame 12 to form a hinged fit. The two ends of the connecting frame 12 are respectively hinged to the top of the arc-shaped sleeve 11 and the top of the clamping seat 6 through the hinge pins 13.

[0018] The bottom end of the clamping seat is fixedly connected to the top end of the support rod, and the bottom end of the clamping seat is also fixedly connected to the base. The interior of the clamping seat forms a receiving space adapted to the outer wall of the natural gas pipeline for accommodating the bending joint of the natural gas pipeline. The arc-shaped sleeve 11 is installed on the outer wall of the clamping seat on one side of the natural gas pipeline body. The top of the arc-shaped sleeve is connected to the top of the clamping seat through a connecting frame to form a hinged fit. The bottom end of the connecting frame is hinged to the top end of the arc-shaped sleeve. A hinge pin is installed on the side of the connecting frame near the clamping seat. The connecting frame is hinged to the top of the clamping seat through the hinge pin, so that the arc-shaped sleeve can be rotated around the hinge point to realize the opening and closing clamping of the natural gas pipeline.

[0019] In some embodiments, a U-shaped seat 14 is installed at the bottom end of the clamping seat 6, and a card seat 10 is fixedly installed at the bottom end of the arc sleeve 11. A T-bolt 16 is hinged inside the card seat 10, and a nut sleeve 15 is fitted on the surface of the T-bolt 16. The T-bolt 16 can be inserted into the slot of the U-shaped seat 14.

[0023] In some embodiments, the bottom end of the base 1 is provided with symmetrically distributed bolt holes, which are used to insert fixing bolts.

[0024] The base has four symmetrically distributed bolt holes at its bottom, located at the four corners of the base. The bolt holes are used to insert fixing bolts and are compatible with M16 standard bolts. During installation, the M16 standard bolts pass through the bolt holes and connect to the pre-embedded bolts or bolt sleeves on the foundation.
