Description

Technical Field

[0001] This utility model specifically relates to a support mechanism for a natural gas pressure tapping pipeline, belonging to the technical field. Background Technology

[0002] In natural gas stations, pressure tapping lines are key components, responsible for collecting pressure signals from pipelines or equipment and transmitting them to instruments such as pressure gauges and transmitters, thereby achieving the important functions of pressure monitoring and control. Currently, pressure tapping lines are typically installed overhead, with an overhead height set at 10 to 15 cm and a line length ranging from 2 to 10 meters.

[0003] However, existing technologies lack effective support structures for pressure tapping pipelines. Due to their inherent weight, these pipelines are highly susceptible to bending and deformation without proper support. This not only leads to loosening at pipeline connections, potentially causing natural gas leaks and posing a serious safety hazard, threatening the safety of station personnel and the stable operation of equipment, but also, the low overhead height makes maintenance personnel prone to tripping over the pipelines while working within the station, resulting in injury. Furthermore, if personnel trip or are subjected to external impact, the unsupported pressure tapping pipelines can be damaged, affecting the normal operation of the natural gas station's pressure monitoring system, leading to inaccurate or even non-existent pressure data collection, and consequently impacting the safe operation and production scheduling of the entire station. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a support mechanism for natural gas pressure tapping pipelines, so as to provide stable support, prevent the pipeline from bending and deforming due to its own weight, and avoid loosening of the joints and natural gas leakage.

[0005] A support mechanism for a natural gas pressure tapping pipeline includes a base, a column extending vertically along the top surface of the base, an adjusting seat adjustable along its axial direction on the column, and a fixing assembly mounted on the adjusting seat. The fixing assembly includes a first clamping plate fixed to the side wall of a connecting plate, a second clamping plate rotatably mounted on the first clamping plate, and both the second clamping plate and the first clamping plate having an inwardly recessed arc-shaped clamping surface on opposite sides. When the second clamping plate rotates to close around a pivot, an annular clamping space for clamping the pressure tapping pipeline is formed between the two arc-shaped clamping surfaces. A locking element is rotatably mounted on the first clamping plate, and the second clamping plate is fixed to the first clamping plate by the locking element.

[0006] Furthermore, a connecting plate is connected to the side wall of the adjusting seat, and the first clamping plate is welded and fixed to the connecting plate.

[0007] Furthermore, the base has a frustum structure, and a rubber pad is attached to the bottom surface of the base, the size of which is adapted to the size of the bottom surface of the base.

[0008] Furthermore, the outer surface of the support column is integrally formed with external threads, and the inner wall of the adjusting seat is provided with internal threads. The adjusting seat is threadedly connected to the support column through the internal threads.

[0009] Furthermore, the locking component includes a screw rod rotatably mounted on the lower outer wall of the first clamping plate, the screw rod being threaded with a nut, and a straight slot being provided on the side wall of the second clamping plate for the screw rod to pass through.

[0010] Furthermore, a knob is fixedly installed on the nut, and the knob has a channel for the screw to pass through.

[0011] Furthermore, a second rotating shaft is installed at the lower end of the first clamping plate, and a bushing is rotatably installed on the second rotating shaft. One end of the screw is fixedly welded to the outer wall of the bushing.

[0012] Furthermore, a rotating shaft is rotatably mounted on the top of the first clamping plate, and a connecting ear is rotatably mounted on the rotating shaft. The end of the connecting ear away from the rotating shaft is connected to the top of the second clamping plate.

[0013] Beneficial effects:

[0014] 1. This utility model, by setting up a support column, adjusting seat and fixing components, can effectively support the pressure tapping pipeline, distribute the pipeline's own weight, avoid the pipeline from bending and deforming due to its own weight, thereby reducing the possibility of loosening at the pipeline interface, reducing the risk of natural gas leakage, and ensuring the safe operation of the natural gas station.

[0015] 2. In this utility model, the threaded connection between the adjusting seat and the support column allows the height of the fixing component to be flexibly adjusted according to actual conditions. Whether it is a pressure tapping pipeline at different heights or an adjustment of the pipeline height due to changes in the layout of station equipment, it can be achieved by rotating the adjusting seat, thus improving the versatility and adaptability of the support mechanism.

[0016] 3. This utility model provides a support mechanism that securely fixes the pressure tapping pipeline at a certain height, preventing the pipeline from swaying or sagging due to lack of support, reducing the risk of maintenance personnel tripping and protecting personnel safety. Simultaneously, the stable support also prevents damage to the pressure tapping pipeline caused by personnel tripping or external impacts, ensuring the normal operation of the pressure monitoring system, guaranteeing the accuracy of pressure data acquisition, and contributing to the safe operation and production scheduling of the station.

[0022] 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.

[0023] Please see Figures 1-4 As shown, a support mechanism for a natural gas pressure tapping pipeline includes a base 1. A support column 2 extending vertically along the top surface of the base 1 is provided. An adjusting seat 3 that can be adjusted along its axial direction is provided on the support column 2. A fixing component is installed on the adjusting seat 3. The fixing component includes a first clamping plate 5 fixed to the side wall of a connecting plate 4. A second clamping plate 7 is rotatably installed on the first clamping plate 5. The second clamping plate 7 and the first clamping plate 5 are both recessed inward on opposite sides to form arc-shaped clamping surfaces. When the second clamping plate 7 is rotated and closed towards the rotating shaft 6, an annular clamping space for clamping the pressure tapping pipeline is formed between the two arc-shaped clamping surfaces. A locking element is rotatably installed on the first clamping plate 5, and the second clamping plate 7 is fixed to the first clamping plate 5 by the locking element.

[0024] Specifically, the base 1 serves as the foundation of the entire support mechanism, providing stable support for the support column 2. The adjusting seat 3 on the support column 2 can be adjusted axially to meet the actual height requirements of the pressure tapping pipeline. The first clamping plate 5 in the fixing assembly is fixed to the connecting plate 4, and the second clamping plate 7 can rotate relative to the first clamping plate 5 via the rotating shaft 6. When the second clamping plate 7 rotates and closes around the rotating shaft 6, the two arc-shaped clamping surfaces form an annular clamping space to clamp the pressure tapping pipeline. Finally, the second clamping plate 7 is fixed to the first clamping plate 5 by the locking element, thereby achieving stable clamping of the pressure tapping pipeline. The adjustability of the adjusting seat 3 allows the support mechanism to adapt to pressure tapping pipelines at different overhead heights, improving the versatility of the device. The rotating design of the first clamping plate 5 and the second clamping plate 7 facilitates the installation and disassembly of the pressure tapping pipeline. The annular clamping space can tightly fit the pressure tapping pipeline, providing stable support, preventing the pipeline from bending and deforming due to its own weight, and avoiding loosening of the interface and natural gas leakage.

[0025] As a technical optimization of this utility model, the side wall of the adjusting seat 3 is connected to the connecting plate 4, and the first clamping plate 5 is welded and fixed to the connecting plate 4.

[0026] Specifically, the first clamping plate 5 can be stably installed on the adjusting seat 3 and move as the position of the adjusting seat 3 on the support column 2 is adjusted. The welding fixation method ensures the stability and reliability of the connection between the first clamping plate 5 and the connecting plate 4, avoids the first clamping plate 5 from shaking or loosening during use, ensures that the fixing components can function properly, and further enhances the support effect on the pressure tapping pipeline.

[0027] As a technical optimization of this utility model, the base 1 has a frustum structure, and a rubber pad is connected to the bottom surface of the base 1. The size of the pad is adapted to the size of the bottom surface of the base 1.

[0028] Specifically, the frustum structure increases the stability of the base 1, and the rubber pad increases the friction between the base 1 and the ground, while also acting as a buffer and shock absorber, thus improving the stability of the entire support mechanism. This reduces the impact of uneven ground or external vibrations on the support mechanism, preventing displacement or shaking of the support mechanism, thereby better ensuring the stable support of the pressure tapping pipeline and reducing the risk of pipeline damage due to unstable support.

[0029] As a technical optimization of this utility model, the outer surface of the support column 2 is integrally formed with external threads, and the inner wall of the adjusting seat 3 is provided with internal threads. The adjusting seat 3 is threadedly connected to the support column 2 through the internal threads.

[0030] Specifically, by rotating the adjusting seat 3, the adjusting seat 3 can be moved up and down along the axis of the support column 2 using the thread transmission principle, thereby achieving position adjustment. The threaded connection method is simple to operate and has high adjustment accuracy. It can accurately adjust the position of the adjusting seat 3 according to actual needs, and then adjust the height of the fixing component to adapt to pressure tapping pipelines at different overhead heights, thus improving the applicability and flexibility of the device.

[0031] As a technical optimization of this utility model, the locking component includes a screw 11 rotatably mounted on the outer wall of the lower end of the first clamping plate 5, a nut 12 threadedly connected to the screw 11, and a straight slot 14 for the screw 11 to pass through is provided on the side wall of the second clamping plate 7.

[0032] Specifically, the screw 11 is passed through the straight groove 14 on the side wall of the second clamping plate 7, and then the second clamping plate 7 is tightly fixed to the first clamping plate 5 by screwing the nut 12 onto the screw 11. This locking method is convenient to operate and can quickly fix and unlock the first clamping plate 5 and the second clamping plate 7, facilitating the installation and disassembly of the pressure tapping pipeline. At the same time, the clamping force can be adjusted by screwing the nut 12 to ensure stable clamping of the pressure tapping pipeline.

[0033] As a technical optimization of this utility model, a knob 13 is fixedly installed on the nut 12, and a channel for the screw 11 to pass through is opened on the knob 13.

[0034] Specifically, the operator can rotate the knob 13 to drive the nut 12 to rotate on the screw 11, thereby locking and unlocking the second clamping plate 7 and the first clamping plate 5. The knob 13 increases the operating torque, making it easier for the operator to tighten and loosen the nut 12, improving the convenience and efficiency of operation. Especially in situations where space is limited or operation is inconvenient, it makes it easier to adjust the fixing components.

[0035] As a technical optimization of this utility model, a rotating shaft 9 is installed at the lower end of the first clamping plate 5, and a bushing 10 is rotatably installed on the rotating shaft 9. One end of the screw 11 is fixedly welded to the outer wall of the bushing 10.

[0036] Specifically, the screw 11 can rotate around the pivot 9. When it is necessary to lock the second clamping plate 7, the screw 11 is rotated to the appropriate position to pass through the straight slot 14, and then the nut 12 is tightened. The rotatable design of the screw 11 makes the installation and disassembly of the pressure tapping pipeline more flexible and avoids the screw 11 from obstructing the operation. When the screw 11 is not needed, it can be rotated aside to facilitate the opening and closing of the second clamping plate 7.

[0037] As a technical optimization of this utility model, a rotating shaft 6 is rotatably installed on the top of the first clamping plate 5, and a connecting ear 8 is rotatably installed on the rotating shaft 6. The end of the connecting ear 8 away from the rotating shaft 6 is connected to the top of the second clamping plate 7.

[0038] Specifically, the second clamping plate 7 rotates around the pivot 6 via the connecting ear 8 to achieve the opening and closing action with the first clamping plate 5. This rotating connection method ensures the smoothness and stability of the rotation of the second clamping plate 7, enabling the second clamping plate 7 to accurately close with the first clamping plate 5 to form an annular clamping space. At the same time, it facilitates the placement and removal of the pressure tapping pipeline, improving the efficiency of installation and maintenance.

[0039] Working principle: This support mechanism is based on base 1, which has a frustum structure and provides a stable standing surface. The rubber pad on its bottom increases friction with the ground, preventing the base from moving and providing some shock absorption. Support column 2 is vertically fixed to base 1. Adjustment seat 3 is threadedly connected to the support column 2 via internal threads on its inner wall and external threads on its outer surface, allowing for axial adjustment along the support column 2. This enables the height of the fixing components to be adjusted according to the actual height requirements of the pressure tapping pipeline.

[0040] In the fixing assembly, the first clamping plate 5 is fixed to the side wall of the connecting plate 4, and the second clamping plate 7 is rotatably connected to the first clamping plate 5 via a rotating shaft 6 and a connecting ear 8. When it is necessary to fix the pressure tapping pipeline, the second clamping plate 7 is rotated to close towards the first clamping plate 5, and the arc-shaped clamping surfaces on opposite sides of the two clamping plates form an annular clamping space, which tightly clamps the pressure tapping pipeline therein.

[0041] The locking element is used to fix the second clamping plate 7 to the first clamping plate 5. The screw 11 is rotatably mounted on the lower outer wall of the first clamping plate 5, and is rotatably connected through the bushing 10 and the rotating shaft 9. After the second clamping plate 7 is closed in place, the screw 11 is passed through the straight slot 14 on the second clamping plate 7, and the nut 12 is screwed on. By rotating the nut 12, the screw 11 is tightened, thereby firmly fixing the second clamping plate 7 to the first clamping plate 5, completing the fixation of the pressure tapping pipeline. The knob 13 on the nut 12 makes it convenient for the operator to rotate the nut 12, improving the ease of operation.
