Description

Technical Field

[0001] This utility model relates to the field of pipeline vibration suppression technology, and in particular to a vibration suppression mechanism for oil and gas pipelines. Background Technology

[0002] When fluids flow at high speeds in oil and gas pipelines, they will generate continuous vibrations due to turbulence, valve opening and closing, and compressor operation. In order to disperse and suppress vibration energy, pipe supports are used to support the pipeline and limit the lateral and longitudinal displacement of the pipeline during vibration, so as to prevent the pipeline from shaking significantly.

[0003] Currently, existing pipe supports are secured to the mounting surface using anchor bolts to ensure their vibration suppression effect. When the pipeline route is changed during maintenance, the bolts between the base plate and the mounting surface must be removed before the pipe support angle can be adjusted. Since the bolt removal process is cumbersome, it not only prolongs the construction period but may also damage the mounting surface due to forced removal, thus affecting the reliability of subsequent pipeline installation. Therefore, we propose a vibration suppression mechanism for oil and gas pipelines to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vibration suppression mechanism for oil and gas pipelines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vibration suppression mechanism for oil and gas pipelines includes a pipe support. A plug is fixedly connected to the bottom end of the pipe support, and a collar is movably sleeved on the outside of the plug. The collar is distributed above a mounting plate. A connecting groove is formed inside the collar, and a guide block is inserted into the connecting groove. A movable block is connected to one end of the guide block, and a connecting rod is fixedly connected to the other end of the guide block, extending to the outside of the collar. Fixed blocks are evenly distributed on the outside of the plug.

[0007] This device, equipped with a plug and a collar, allows for adjustment of the pipe support angle by cooperating with the plug and collar during pipe routing changes. This eliminates the need for workers to pull the anchor bolts out of the mounting plate, thus significantly improving the ease of use of the device.

[0008] Preferably, the top of the collar is symmetrically provided with slots, and the inner wall of each slot is connected to a roller via a bearing, and the bottom of the tube support is provided with an annular groove that matches the roller.

[0009] Preferably, the collar is fixedly connected to a mating block on its side, and bolts are symmetrically inserted inside the mating block. The mounting plate is evenly provided with screw holes that match the bolts.

[0010] Preferably, a pull bar is fixedly connected to the side of the connecting rod away from the collar, and the pull bar is configured as an arc-shaped structure.

[0011] Preferably, a spring is sleeved on the outer side of the connecting rod, with one end of the spring connected to the guide block and the other end of the spring connected to the inner wall of the connecting groove.

[0012] Preferably, the docking blocks are provided in two sets, and the two sets of docking blocks are configured in an L-shaped structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device, equipped with a plug and a collar, allows for adjustment of the pipe support angle during pipeline rerouting by cooperating with the plug and collar. This eliminates the need for workers to pull the anchor bolts out of the mounting plate, thus significantly improving the ease of use of the device.

[0015] 2. This device is equipped with a docking block and screw holes. During use, the horizontal position of the insert block can be quickly adjusted by the cooperation of the docking block and screw holes, thereby further improving the flexibility and convenience of the device during use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A vibration suppression mechanism for oil and gas pipelines includes a pipe support 1. A plug 2 is fixedly connected to the bottom end of the pipe support 1, and a collar 3 is movably sleeved on the outer side of the plug 2. The support and vibration suppression principle of the pipe support 1 for the oil and gas pipeline is a mature existing technology, which will not be elaborated upon here. The collar 3 is distributed above the mounting plate 4. The longitudinal section of the plug 2 is T-shaped, thus meeting its rotation requirements inside the collar 3. A connecting groove 5 is provided inside the collar 3, and a guide block 10 is inserted inside the connecting groove 5. One end of the guide block 10 is connected to a moving block 6, and the other end of the guide block 10 is fixedly connected to a connecting rod 7, which extends to the outside of the collar 3. Fixed blocks 11 are evenly distributed on the outer side of the plug 2. In use, the moving block 6 is inserted between two sets of fixed blocks 11, thereby limiting the position of the plug 2.

[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the top of the collar 3 is symmetrically provided with slots, and the inner wall of each slot is connected to a roller 12 through a bearing. The bottom of the tube support 1 is provided with an annular groove that matches the roller 12. During use, the weight of the tube support 1 can be distributed through the arrangement of each set of rollers 12, and the resistance when the tube support 1 rotates can be effectively reduced, thereby effectively improving the convenience of using this device.

[0024] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the side of the collar 3 is fixedly connected to the mating block 13, and bolts are symmetrically inserted inside the mating block 13. The mounting plate 4 is evenly provided with screw holes 14 that are compatible with the bolts. In use, the lateral position of the pipe support 1 can be adjusted by the mating block 13 and each set of screw holes 14, thereby further improving the flexibility of the device in use.

[0025] Furthermore, refer to Figure 1 and Figure 2 It can be seen that a pull bar 8 is fixedly connected to the side of the connecting rod 7 away from the collar 3, and the pull bar 8 is set with an arc structure. In use, the two sets of pull bars 8 provide a force point for the staff, so that the staff can quickly pull the two sets of connecting rods 7 to move under force.

[0026] Furthermore, refer to Figure 4It can be seen that a spring 9 is sleeved on the outside of the connecting rod 7, and one end of the spring 9 is connected to the guide block 10, and the other end of the spring 9 is connected to the inner wall of the connecting groove 5. Through the elastic force of the spring 9 itself, the tightness of the moving block 6 being inserted into the two sets of fixed blocks 11 can be effectively guaranteed, thereby effectively improving the limiting effect of the moving block 6 on the insert block 2.

[0027] Furthermore, refer to Figure 1 It can be seen that there are two sets of docking blocks 13, and the two sets of docking blocks 13 are set in an L-shaped structure. The setting of the two sets of docking blocks 13 can effectively ensure the reliability of the connection process between the collar 3 and the mounting plate 4. Since the docking blocks 13 are set in an L-shape, the collar 3 can move stably in the specified direction, so that the staff can use bolts to connect the collar 3 and the mounting plate 4 later.

[0028] Working principle: When using this utility model, the operator can first place the mounting plate 4 at the bottom of the pipe support 1 in a suitable area, and then use anchor bolts to connect and fix the mounting plate 4 to the mounting surface. Then, the operator can place the oil and gas pipeline that needs to suppress vibration on the arc-shaped support plate inside the pipe support 1, and then use bolts to fix the oil and gas pipeline. During the use of the oil and gas pipeline, the vibration can be suppressed by the rubber pad glued to the inner wall of the arc-shaped support plate.

[0029] When changing the pipeline route during oil and gas pipeline maintenance, the worker can first pull the two sets of pulling bars 8 to move them laterally, which will drive the two sets of connecting rods 7, guide blocks 10 and moving blocks 6 to move simultaneously. The moving block 6 can be pulled out from the position between the two sets of fixed blocks 11 and embedded into the inside of the connecting groove 5 for temporary storage. Then the worker can push the pipe support 1 to rotate, so that the insertion block 2 is simultaneously rotated inside the collar 3 under force, thereby realizing the rapid adjustment of the orientation of the pipe support 1. After the adjustment is completed, the worker can stop pulling the pulling bars 8, so that the moving block 6 can be locked into the inner position of the corresponding two sets of fixed blocks 11 by the elastic force of the spring 9, so as to limit the insertion block 2. The above is the entire working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
