Description

Technical Field

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

[0002] Gas pipelines are pipelines mainly used to transport natural gas, liquefied petroleum gas, and manufactured gas. In long-distance transportation, gas pipelines specifically refer to those transporting natural gas. In urban areas, gas pipelines refer to those transporting natural gas, liquefied petroleum gas, manufactured gas, and other media. When transporting natural gas within a pipeline, the weight of the pipeline itself is increased, which leads to an increase in the load on the pipeline nodes. Support devices are usually installed to improve the protection of the gas pipeline nodes.

[0003] A search revealed an existing technology (application number: CN201921567328.6) for a gas pipeline support device, which describes "including a first fixed seat, a second fixed seat, a second support plate, and a bearing. Support rods are welded to both sides of the first fixed seat, and one end of each support rod is welded to the outer wall of a lower support sleeve. The upper surface of the first fixed seat is welded to the outer wall of the lower support sleeve. First support plates are welded to both sides of the second support plate, and a fixed plate is welded to the top of the two first support plates. An upper support sleeve is welded to the outer ring of the bearing. A support plate is screwed to the bottom of the second support plate, and a connecting rod is welded to the bottom of the support plate. A partition is welded inside the second fixed seat, and the connecting rod passes through the interior of the partition. A second support rod and a third support rod are respectively hinged to the end of the connecting rod away from the support plate. A first support rod is hinged to one end of both the second and third support rods. Baffles are welded to both sides of the inner wall of the second fixed seat, and a first spring is welded to one side of each baffle." This utility model supports the gas pipeline by placing the pipe body on the lower support sleeve, rotating the threaded rod with the throttle, and causing the upper support sleeve to clamp the upper part of the pipe body.

[0004] However, although the existing technology achieves the upper clamping of the pipe body by moving the threaded rod into the fixed plate to support the gas pipeline, it still has some shortcomings: during the installation of the pipe body, it is necessary to pass the pipe body through the second support plate, the first support plate and the fixed plate, which requires a large installation space and is not conducive to the operation and use of the staff.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] like Figures 1 to 4As shown, this embodiment provides a gas pipeline node protection device, including: a fixing component 1, including a load ring 13, disposed above a support plate 27; a lifting component 2, including a support plate 27, the support plate 27 being used to support the fixing component 1, and an adjusting component disposed below the support plate 27 for adjusting the height of the support plate 27, the adjusting component including a threaded rod 22 and a threaded rod 23, a second slider 29 being threadedly connected to the threaded rod 22, and a first slider 25 being threadedly connected to the threaded rod 23; and a support component 3, including a base 32, on which a support block 33 is disposed, the support block 33 being disposed in two sets, and a vertical support structure 31 being disposed in the middle of the support block 33.

[0030] In this embodiment, the fixing component 1, the adjusting component, and the supporting component 3 constitute the gas pipeline node protection device involved in this application, realizing a gas pipeline node protection device.

[0031] In this embodiment, the fixing component 1 is usually made of metal or polymer material, which can withstand external forces such as pressure, tension and vibration during the operation of the gas pipeline, and also has good corrosion resistance.

[0032] In this embodiment, a fixing block is fixed on the support plate 27, which can fix the load ring 13 and the support block 27, so that the support plate 27 can stably support the fixing component 1.

[0033] It should be noted that when the lifting component 2 is adjusted to the required height, the vertical support structure 31 provides stable support. According to the work requirements, the gas pipeline node is fixed in the fixing component 1, which can relieve the pressure at the pipeline node and complete the protection of the pipeline.

[0034] Specifically, the fixing component 1 also includes: a fixing ring 11, which is disposed above the loading ring 13; and a gasket 12, which is fixed to the inner wall of the loading ring 13 and the inner wall of the fixing ring 11, and is arranged symmetrically.

[0035] In this embodiment, the gas pipeline is surrounded by the fixing ring 11 and the carrying ring 13. The positioning pin and the pin hole are engaged to fix the gas pipeline in the horizontal direction. The gasket 12 plays the role of buffering and protecting the gas pipeline to prevent damage to the pipeline surface.

[0036] Specifically, the top of the carrying ring 13 is provided with a pin hole, and the bottom of the fixing ring 11 is provided with a positioning pin. The positioning pin slides in the pin hole and is used to fix the gas pipeline.

[0037] In a preferred embodiment, the positioning pin slides within the pin hole, and the positioning pin and pin hole, together with the fixing ring and the load ring 13, securely fix the gas pipeline within the protective device, thereby enhancing the stability of the gas pipeline.

[0038] Example 2:

[0039] Based on Embodiment 1, in order to adjust the lifting height of the fixed component and adapt to various working conditions, a lifting component 2 is provided on the base 32.

[0040] Specifically, the lifting assembly 2 also includes: a first connecting rod 26, with its bottom end hinged to a first slider 25 and its top end hinged to a support plate 27; and a second connecting rod 28, with its bottom end hinged to a second slider 29 and its top end hinged to a support plate 27.

[0041] It should be noted that when slider 1 25 and slider 29 move under the drive of threaded rod 1 22 and threaded rod 23, slider 1 25 and slider 29 move closer or further apart, and the motion is transmitted through the hinge of connecting rod 1 26 and connecting rod 28, thereby raising and lowering the support plate 27, and realizing the adjustment of the height of the fixed component and the gas pipeline.

[0042] Specifically, the adjustment assembly also includes: a guide rod 24, a threaded rod 22 fixed on the support block 33, a threaded rod 22 slidably connected to the guide rod 24, and rotating through a set of support blocks 33; a threaded rod 23 slidably connected to the guide rod 24 and rotating through another set of support blocks 33; and a knob 21 fixed on the threaded rod 22 at one end away from the threaded rod 23, used to adjust the movement of slider 25 and slider 29.

[0043] In a preferred embodiment, the rotation of threaded rod 22 drives threaded rod 23 to rotate synchronously. The slider 25 on threaded rod 22 and the slider 29 on threaded rod 23 will move in opposite or opposite directions in a straight line and slide on the guide rod 24, which avoids them from deviating or shaking during the movement, ensuring the stability of the entire adjustment process. This makes the entire lifting and adjusting action smoother and more reliable, and can adjust the gas pipeline to the required height position, thus improving the practicality of the device.

[0044] Example 3:

[0045] Based on Example 2, in order to ensure the stable lifting and lowering of the gas pipeline and meet various working requirements, the threaded rod 22 and the threaded rod 23 have opposite thread directions, and a vertical support structure 31 is also provided on the base 32.

[0046] Specifically, threaded rod 22 and threaded rod 23 are located on the same straight line. Threaded rod 22 and threaded rod 23 are fixedly connected by a fixed sleeve. The threaded relationships of threaded rod 22 and threaded rod 23 are set in opposite directions.

[0047] It should be noted that when the knob 21 is rotated to rotate the threaded rod 22 and the threaded rod 23, the slider 25 will move in one direction along the threaded rod 22 due to the action of the threads; at the same time, because the threaded rod 23 rotates synchronously with the threaded rod 22 and the threads are opposite, the slider 29 will move in the opposite direction along the threaded rod 23, so that the slider 25 and the slider 29 move closer or further apart, and the support plate 27 is raised and lowered synchronously. This ensures that the support plate 27 remains balanced during the raising and lowering process, and ensures that the raising and lowering adjustment of the gas pipeline is more uniform and stable, meeting different installation and maintenance requirements.

[0048] Specifically, the vertical support structure 31 also includes: a bracket 312, fixed in the middle of the base 32; a telescopic rod 311, with its fixed end fixed to the bracket 312 and its telescopic end fixed to the support plate 27; threaded rod 23 and threaded rod 22 rotatably connected to the bracket 312; and slider 1 25 and slider 29 arranged on both sides of the bracket 312.

[0049] In this embodiment, the telescopic rod 311 can extend and retract according to the lifting and lowering action of the support plate 27. Its function is to assist in supporting the support plate 27, enhance the stability of the entire support structure, and prevent the support plate 27 from swaying or becoming unstable during the lifting and lowering process. At the same time, the rotatable connection between the threaded rod 23 and the threaded rod 22 and the bracket 312 ensures that the slider 25 and the slider 29 can move smoothly. In turn, the lifting assembly realizes the lifting and lowering of the support plate 27, so that the entire protective device can maintain good stability under different working conditions, providing reliable support and protection for the gas pipeline and ensuring the safety of the gas pipeline at the node.

[0050] In use, when supporting the pipeline, the construction personnel first turn knob 21, which drives the two threaded rods with opposite threads, threaded rod 22 and threaded rod 23, to rotate. This causes sliders 25 and 29 to move closer or further apart along guide rod 24. When sliders 25 of the lifting assembly move closer together, connecting rods 26 and 28 move closer together. With the assistance of telescopic rod 311, the height of support plate 27 will rise. When sliders 25 and 29 move further apart, connecting rods 26 and 28 move further apart. With the assistance of telescopic rod 311, the height of support plate 27 will fall. The construction personnel then adjust the height of support plate 27 according to the height of the pipeline support, so that the load ring 13 on support plate 27 contacts the outer wall of the pipeline. Finally, the fixing ring 11 is inserted into the load ring 13 to complete the fixing of the pipeline.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
