Description

Technical Field

[0001] This utility model relates to the field of gas engineering technology, specifically to a gas engineering pipeline protection device. Background Technology

[0002] Gas engineering refers to the systematic engineering involving the production, transmission, distribution, and use of gas. It includes facilities, equipment, and devices from gas sources (such as storage and distribution stations and gate stations) through the transmission and distribution system to the user end. It covers municipal gas facilities, gas facilities in public areas of building zones, and indoor gas facilities, aiming to ensure a safe and efficient gas supply. Gas pipeline protection devices are key equipment in gas engineering, mainly used for physical protection during pipeline installation and operation. Common types include suspension protection devices, corrosion protection devices, and connection and buffer devices.

[0003] A gas pipeline protection device, as described in application number CN202420646460.0 and authorized announcement date 20250408, includes a fixing plate, an L-shaped support plate below the fixing plate, an L-shaped carrier plate above the L-shaped support plate, and a shock-absorbing rubber block with a concave arc-shaped top fixedly connected to the bottom inner wall of the L-shaped carrier plate. A gas pipeline is movably held in place by the top of the shock-absorbing rubber block. A box-shaped plate with an open bottom is located above the L-shaped carrier plate. This utility model, through a series of structures, facilitates flexible adjustment of the suspension support height for the gas pipeline according to suspension support requirements. It facilitates stable and anti-detachment fixation of the gas pipeline through bottom support combined with upper compression. It allows adjustment of the curvature of the arc-shaped elastic pressure plate according to different specifications of gas pipelines, improving applicability and stability of the compression and anti-detachment measures for the gas pipeline. Furthermore, it facilitates effective buffering and stress relief during hard vibrations of the gas pipeline, improving the buffering effect and thus enhancing safety.

[0004] Traditional suspension protection devices rely on multi-layered mechanical structures, resulting in cumbersome installation steps, especially inefficient construction in confined spaces. Furthermore, disassembly requires the complete removal of components, making it impossible to quickly inspect individual parts. Therefore, there is an urgent need to design a gas pipeline protection device to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a gas pipeline protection device to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A gas pipeline protection device includes an upper mounting assembly and a lower mounting assembly, which are installed together. The upper mounting assembly includes an upper mounting base. Slide rails are integrally formed on both outer walls of the bottom of the upper mounting base. Mounting grooves and recesses are formed on both outer walls of the upper mounting base, with the recesses located above the mounting grooves. A tensioning assembly is provided inside the recesses and mounting grooves on one side of the upper mounting base. The tensioning assembly includes an adjusting screw, which is mounted inside the mounting groove via a bearing. A hexagonal rotating head is mounted on the top of the adjusting screw via a flat key and is located inside the recess. A sliding block is threaded to the bottom of the adjusting screw and is slidably connected inside the mounting groove. A hook is integrally formed on one outer wall of the sliding block.

[0008] The lower mounting assembly includes a lower mounting base. Two sliding grooves are formed on one outer wall of the lower mounting base. The lower mounting base is slidably mounted on two slide rails through the two sliding grooves. Mounting blocks are bolted to both outer walls of the lower mounting base, and a rope is bolted to one outer wall of the mounting block. The rope is fastened to a hook.

[0009] Furthermore, the upper mounting base has ear plates integrally formed on both outer walls, and six through holes are opened on one side of the top of the ear plates.

[0010] Furthermore, a limiting rod is slidably inserted inside the through hole, and a self-locking nut is threadedly connected to the bottom end of the limiting rod. The self-locking nut contacts the ear plate, and a flange is welded to the top end of the limiting rod.

[0011] Furthermore, the upper mounting base has two integrally formed upper arc-shaped limiting plates inside, and a highly elastic rubber block is adhered to one side of the outer wall of the upper arc-shaped limiting plate.

[0012] Furthermore, the lower mounting base has two integrally formed lower arc-shaped limiting plates inside, and a high-elasticity rubber block is bonded to one side of the outer wall of the lower arc-shaped limiting plate.

[0013] Furthermore, two mounting cavities are formed on one side of the outer wall of the lower mounting base, and the mounting cavities are interconnected with the sliding groove. A sliding block is slidably inserted inside the mounting cavity, and one end of the sliding block is integrally formed with a plug rod, one end of which is located inside the sliding groove.

[0014] Furthermore, a compression spring is bolted to one end of the sliding block, and the compression spring is bolted to one side of the inner wall of the mounting cavity.

[0015] Furthermore, a limiting hole is provided on one side of the outer wall of the slide rail, and one end of the plug rod is inserted into the limiting hole. The preload of the compression spring keeps the plug rod in the inserted state. Pressing the sliding block can release the locking between the plug rod and the limiting hole.

[0016] In the above technical solution, the gas pipeline protection device provided by this utility model has the following beneficial effects:

[0017] (1) This utility model achieves rapid alignment and bidirectional tensioning of the upper and lower installation components by sliding the upper and lower installation components with the sliding rails and grooves, combined with the adjusting screw of the tensioning component driving the sliding block and hook to fasten the rope. This solves the problem of complicated installation caused by traditional multi-layer structures. Moreover, the entire installation process does not require complicated tools or complicated steps, which significantly simplifies the operation. It is particularly beneficial for efficient installation and preliminary adjustment in gas construction sites with limited space. It solves the problems of complicated installation steps and low efficiency in narrow spaces of traditional devices. Furthermore, the modular design of the upper and lower installation components allows for individual disassembly of the components, avoiding overall disassembly and reducing maintenance costs.

[0018] (2) The design of the upper arc-shaped limiting plate and the lower arc-shaped limiting plate of this utility model can effectively wrap and position gas pipelines of different diameters, especially common cylindrical pipelines. The introduction of the high elasticity rubber block provides excellent buffer performance, which can effectively absorb the vibration and displacement energy generated by the pipeline due to thermal expansion and contraction, fluid pulsation or slight external force impact, avoid direct hard collision and friction between the pipeline and the rigid metal limiting plate, greatly reduce the risk of damage to the outer anti-corrosion layer of the pipeline and wear of the pipe body, and improve the safety of pipeline operation.

[0019] (3) The elastic self-locking structure composed of the sliding block, plug rod and compression spring of this utility model ensures that the upper and lower installation components can be firmly locked after being adjusted to the position, effectively preventing accidental slippage and disengagement caused by vibration or external force during hoisting, tensioning or operation, greatly enhancing the stability and safety of the device's working state. At the same time, the press-to-unlock method makes the position adjustment operation still convenient and flexible, taking into account both safety and adjustability, realizing quick disassembly and assembly without tools, and solving the risk of pipeline displacement caused by the lack of bidirectional locking in traditional suspension devices.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-5 As shown in the figure, a gas pipeline protection device provided by this utility model includes an upper mounting component 1 and a lower mounting component 2. The upper mounting component 1 and the lower mounting component 2 are installed together. The upper mounting component 1 includes an upper mounting base 3. The outer walls of both sides of the bottom of the upper mounting base 3 are integrally formed with slide rails 4. The outer walls of both sides of the upper mounting base 3 are provided with mounting grooves 13 and recesses 14, and the recesses 14 are located above the mounting grooves 13. The recesses 14 and mounting grooves 13 on one side of the upper mounting base 3 are provided with a tensioning component 15. The tensioning component 15 includes an adjusting screw 16. The adjusting screw 16 is installed in the mounting groove 13 through a bearing. The top of the adjusting screw 16 is installed with a hexagonal rotating head 17 through a flat key, and the hexagonal rotating head 17 is located in the recess 14. The bottom end of the adjusting screw 16 is threadedly connected to a sliding block 18, and the sliding block 18 is slidably connected in the mounting groove 13. The outer wall of one side of the sliding block 18 is integrally formed with a hook 19.

[0030] The lower mounting component 2 includes a lower mounting base 20. Two grooves 21 are formed on one side of the outer wall of the lower mounting base 20. The lower mounting base 20 is slidably mounted on two slide rails 4 through the two grooves 21. Mounting blocks 24 are bolted to both sides of the outer wall of the lower mounting base 20, and a rope 25 is bolted to one side of the outer wall of the mounting block 24. The rope 25 is fastened to the hook 19.

[0031] Specifically, in this embodiment, an upper mounting component 1 and a lower mounting component 2 are included, which are installed together. The upper mounting component 1 includes an upper mounting base 3. The outer walls on both sides of the bottom of the upper mounting base 3 are integrally formed with slide rails 4. The slide rails 4 facilitate the installation of the lower mounting base 20 on the upper mounting base 3. The outer walls on both sides of the upper mounting base 3 are provided with mounting grooves 13 and recesses 14, with the recesses 14 located above the mounting grooves 13. A tensioning component 15 is provided inside the recesses 14 and mounting grooves 13 on one side of the upper mounting base 3. The tensioning assembly 15 includes an adjusting screw 16, which is mounted inside the mounting groove 13 via a bearing. A hexagonal rotating head 17 is mounted on the top of the adjusting screw 16 via a flat key. The hexagonal rotating head 17 facilitates the installation worker to rotate the adjusting screw 16 and is located inside the groove 14. A sliding block 18 is threadedly connected to the bottom of the adjusting screw 16 and is slidably connected inside the mounting groove 13. A hook 19 is integrally formed on one side of the outer wall of the sliding block 18, which can fix the rope 25.

[0032] The lower mounting component 2 includes a lower mounting base 20. Two grooves 21 are formed on one outer wall of the lower mounting base 20. The lower mounting base 20 slides along the slide rails 4 of the upper mounting base 3 via the grooves 21, initially achieving horizontal alignment of the upper and lower components. The lower mounting base 20 is slidably mounted on the two slide rails 4 via the two grooves 21. Mounting blocks 24 are bolted to both outer walls of the lower mounting base 20, and ropes 25 are bolted to one outer wall of each mounting block 24. When the lower mounting base 20 is engaged with the upper mounting base 3, the ropes 25 are... The hook 19 is inserted into the side of the upper mounting base 3. Then, the hexagonal rotating head 17 is rotated to drive the adjusting screw 16 to rotate, which causes the sliding block 18 to move down in the mounting groove 13. This allows the hook 19 to hook the ropes 25 on both sides of the lower mounting base 20. The adjusting screw 16 is rotated again, and the sliding block 18 continues to move down. The ropes 25 pull the lower mounting base 20 up, so that the upper arc-shaped limiting plate 11 and the lower arc-shaped limiting plate 22 tightly press the pipe together, eliminating installation gaps and enhancing the stability of the fixation. The ropes 25 are fastened in the hook 19.

[0033] This utility model provides a gas pipeline protection device. Through the sliding cooperation of the slide rail 4 and slide groove 21 of the upper installation component 1 and the lower installation component 2, combined with the adjustment screw 16 of the tensioning component 15 driving the sliding block 18 and hook 19 to fasten the rope 25, the upper installation component 1 and the lower installation component 2 can be quickly aligned and installed and tightened in both directions. This solves the problem of complicated installation caused by traditional multi-layer structures. Moreover, the entire installation process does not require complicated tools or complicated steps, which significantly simplifies the operation. It is particularly beneficial for efficient installation and initial adjustment in gas construction sites with limited space. It solves the problems of complicated installation steps and low efficiency in narrow spaces of traditional devices. In addition, the modular design of the upper installation component 1 and the lower installation component 2 allows for individual disassembly of the components, avoiding overall disassembly and reducing maintenance costs.

[0034] In one embodiment provided by this utility model, such as Figure 2 As shown, the upper mounting base 3 has ear plates 6 integrally formed on both outer walls, and six through holes 7 are opened on the outer wall of the top side of the ear plate 6. Limiting rods 8 are slidably inserted into the through holes 7, and self-locking nuts 10 are threadedly connected to the bottom end of the limiting rods 8. The bottom end of the limiting rods 8 passes through the through holes 7 and is tightened and fixed by the self-locking nuts 10. The self-locking nuts 10 are in contact with the ear plates 6. A flange 9 is welded to the top of the limiting rods 8 to form a rigid connection. The flange 9 at the top of the limiting rods 8 can be fixed to the support structure by bolts.

[0035] In another embodiment provided by this utility model, such as Figure 2 and Figure 4 As shown, the upper mounting base 3 has two integrally formed upper arc-shaped limiting plates 11, and a high-elasticity rubber block 12 is bonded to one side of the outer wall of the upper arc-shaped limiting plate 11. The lower mounting base 20 has two integrally formed lower arc-shaped limiting plates 22, and a high-elasticity rubber block 23 is bonded to one side of the outer wall of the lower arc-shaped limiting plate 22. When the pipeline is fixed by this device, the gas pipeline is placed on the high-elasticity rubber block 23 of the lower arc-shaped limiting plate 22. Then, the high-elasticity rubber block 12 of the upper arc-shaped limiting plate 11 is attached downward to the top of the pipeline, forming a flexible clamping between the upper and lower parts to buffer thermal expansion and contraction or vibration impact. The upper arc-shaped limiting plate 11, the lower arc-shaped limiting plate 22, and the high-elasticity rubber block 12 and the high-elasticity rubber block 23 work together to wrap the pipeline, absorb vibration and prevent hard friction.

[0036] In another embodiment provided by this utility model, such as Figure 4-5As shown, two mounting cavities 26 are formed on one side of the outer wall of the lower mounting base 20, and the mounting cavities 26 are interconnected with the slide groove 21. A sliding block 28 is slidably inserted into the mounting cavity 26, and a connecting rod 29 is integrally formed at one end of the sliding block 28. One end of the connecting rod 29 is located inside the slide groove 21, and a compression spring 27 is bolted to one end of the sliding block 28. When the slide rail 4 and the slide groove 21 slide to the target position, the compression spring 27 pushes the sliding block 28, so that the connecting rod 29 automatically inserts into the limiting hole 5 of the slide rail 4. This prevents the upper and lower components from accidentally coming off; conversely, pressing the sliding block 28 overcomes the preload of the compression spring 27, causing the plug rod 29 to exit the limiting hole 5, allowing it to slide and adjust its position again without the need for tools. One end of the compression spring 27 is bolted to one side of the inner wall of the installation cavity 26, and a limiting hole 5 is provided on one side of the outer wall of the slide rail 4. One end of the plug rod 29 is inserted into the limiting hole 5, and the preload of the compression spring 27 keeps the plug rod 29 in the inserted state. Pressing the sliding block 28 can release the locking between the plug rod 29 and the limiting hole 5.

[0037] Working principle: The upper mounting assembly 1 is fixed to an external support structure, such as a steel frame or wall, via the ear plates 6 on both sides of the upper mounting base 3. The six through holes 7 on the ear plates 6 provide multiple position options. The bottom end of the limiting rod 8 passes through the through holes 7 and is tightened with a self-locking nut 10 to form a rigid connection. The flange 9 at the top of the limiting rod 8 can be fixed to the support structure with bolts. Subsequently, the sliding groove 21 of the lower mounting base 20 is aligned with the sliding rail 4 at the bottom of the upper mounting base 3, and pushed in along the sliding rail 4 to complete the initial assembly. Then, the gas pipeline is placed on the two lower arc-shaped limiting plates 22 of the lower mounting base 20. During this process, the pipeline's connecting flange can be locked between the two lower arc-shaped limiting plates 22, and the highly elastic rubber block 23 on its surface provides bottom cushioning. Subsequent... As the lower mounting base 20 continues to slide, when the slide groove 21 slides to the target position, the compression spring 27 in the mounting cavity 26 on the side wall of the lower mounting base 20 automatically pushes the sliding block 28, so that the plug rod 29 is inserted into the limiting hole 5 on the slide rail 4 and locked in position. During this process, the two upper arc-shaped limiting plates 11 of the upper mounting base 3 cover the top of the pipe and press the pipe with the high elastic rubber block 12. Then, the rope 25 is hooked into the hook 19 on the side of the upper mounting base 3. Then, the hexagonal rotating head 17 in the groove 14 is rotated to drive the adjusting screw 16 to rotate, thereby driving the threaded sliding block 18 to slide up and down in the mounting groove 13. After that, the height of the hook 19 changes, tightening or loosening the rope 25, realizing the compression and sealing of the upper mounting component 1 and the lower mounting component 2.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
