Description

Technical Field

[0001] This utility model relates to the field of natural gas pipeline technology, and in particular to an overhead support structure for natural gas pipelines. Background Technology

[0002] The overhead support structure for natural gas pipelines is a key supporting equipment in the natural gas transmission system. It is mainly used to fix the natural gas pipelines to the walls, supports and other carriers in the air to avoid the pipelines from direct contact with the ground and being corroded or damaged by external forces. At the same time, it is necessary to ensure the stability of the pipelines during long-term transportation. The rationality of its structure directly affects the installation safety and service life of the natural gas pipelines.

[0003] In the practical application of existing overhead support structures for natural gas pipelines, there are obvious problems with insufficient adaptability and support stability: most support structures can only provide fixed support for a single horizontal or vertical pipeline. When the pipeline installation direction needs to be adjusted, different types of support devices need to be replaced, which is cumbersome and increases costs. Therefore, we propose an overhead support structure for natural gas pipelines to solve this problem. Utility Model Content

The lower arc-shaped plate is connected to an upper arc-shaped plate by a connecting mechanism. Side support columns are fixedly installed on the sides of the lower arc-shaped plate and the upper arc-shaped plate that are far apart from each other. Both sides of the lower side support column are provided with support arc plates, which are adapted to the side support column. The two support arc plates are in contact with the bottom of the lower arc plate. The bottom of the two support arc plates is fixedly installed with swing rods.

[0007] Preferably, the connecting mechanism includes four side plates. The two upper side plates are fixedly installed on the two sides of the upper arc plate, and the two lower side plates are fixedly installed on the two sides of the lower arc plate. Four connecting studs are fixedly installed on the top of the two lower side plates, and four connecting holes are opened on the two upper side plates. One end of each of the four connecting studs passes through the four connecting holes and is threaded with a connecting bolt.

[0008] Preferably, a connecting block is fixedly installed on the side of the mounting plate, and a rotating shaft is fixedly installed on both sides of the connecting block, with the two swing rods respectively rotatably sleeved on the two rotating shafts.

[0017] 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.

[0018] Please see Figure 1 - Figure 4 The embodiments provided by this utility model are as follows: The overhead support structure for natural gas pipeline includes a mounting plate 1, a mounting shaft 2 fixedly mounted on the side of the mounting plate 1, and a rotating disk 13 rotatably mounted on one side of the mounting shaft 2. The rotating disk 13 is connected to the side of the mounting shaft 2 through four limiting mechanisms. The side of the rotating disk 13 is fixedly installed with a lower arc plate 5 by a fixing block 8. The lower arc plate 5 is connected to an upper arc plate 4 by a connecting mechanism. The mounting plate 1 has four mounting holes. Protective pads are installed on the sides of the upper arc plate 4 and the lower arc plate 5 that are close to each other. Side support columns 3 are fixedly installed on the sides of the lower arc plate 5 and the upper arc plate 4 that are far apart from each other. Both sides of the lower side support column 3 are provided with support arc plates 9. The support arc plates 9 are adapted to the side support column 3. The two support arc plates 9 are in contact with the bottom of the lower arc plate 5. The bottom of the two support arc plates 9 are fixedly installed with swing rods 7. The two swing rods 7 are rotatably installed on the side of the mounting plate 1. The two swing rods 7 are installed in cooperation with the mounting shaft 2 through the adjustment mechanism.

[0019] like Figure 3As shown, the limiting mechanism includes an arc-shaped block 16 fixedly installed on the side of the rotating disk 13. A limiting hole is opened on the top of the arc-shaped block 16, and a limiting bolt 17 is installed in the limiting hole. Four threaded limiting grooves are opened on the outer side of the mounting shaft 2. The limiting bolt 17 is threadedly installed in the corresponding threaded limiting groove. The four limiting bolts 17 are rotated to move out of the four threaded limiting grooves. Then the rotating disk 13 is rotated to rotate the lower arc-shaped plate 5 by ninety degrees. Then the four limiting bolts 17 are rotated in the opposite direction to enter the corresponding four threaded limiting grooves for fixing.

[0020] like Figure 2 As shown, the connecting mechanism includes four side plates 11. The two upper side plates 11 are fixedly installed on both sides of the upper arc-shaped plate 4, and the two lower side plates 11 are fixedly installed on both sides of the lower arc-shaped plate 5. Four connecting studs 12 are fixedly installed on the top of the two lower side plates 11, and four connecting holes are opened on the two upper side plates 11. One end of each of the four connecting studs 12 passes through the four connecting holes and is threaded with a connecting bolt 10. After removing the four connecting bolts 10, the upper arc-shaped plate 4 is taken out. After the natural gas pipeline is placed on the lower arc-shaped plate 5, the natural gas pipeline can be fixed by tightening the four connecting bolts 10.

[0021] like Figure 2 As shown, a connecting block 6 is fixedly installed on the side of the mounting plate 1, and a rotating shaft is fixedly installed on both sides of the connecting block 6. Two swing rods 7 are respectively rotatably sleeved on the two rotating shafts. The connection block 6 and the rotating shafts facilitate the limiting of the swing rods 7.

[0022] like Figure 2 and Figure 4 As shown, the adjustment mechanism includes a synchronizing rod 18 fixedly installed on the sides of two swing rods 7 close to each other. A rotating rod 22 is rotatably sleeved on the synchronizing rod 18. An adjusting stud 19 is rotatably installed on the top of the rotating rod 22, and an adjusting nut 20 is threaded onto the adjusting stud 19. A groove 14 is opened on the top of the mounting shaft 2, and an adjusting hole is opened on the bottom inner wall of the groove 14. The adjusting stud 19 is located in the adjusting hole, and the bottom of the adjusting nut 20 contacts the bottom inner wall of the groove 14. A pulling block 21 is fixedly installed on the top of the adjusting stud 19. When the natural gas pipeline is upward, the adjusting nut 20 is first rotated to make it spiral upward on the adjusting stud 19. At this time, the adjusting stud 19 can move downward. The downward movement of the adjusting stud 19 drives the rotating rod 22 to rotate. The rotation of the rotating rod 22 drives the synchronizing rod 18, the two swing rods 7, and the two supporting arc plates 9 to move downward. The two supporting arc plates 9 separate from the bottom of the lower arc plate 5 until they no longer affect the rotation position of the lower arc plate 5.

[0023] like Figure 3As shown, a central column 15 is rotatably mounted on the side of the mounting shaft 2. The end of the central column 15 away from the mounting shaft 2 is fixedly mounted on the side of the rotating disk 13. The central column 15, the mounting shaft 2, and the rotating disk 13 are coaxially arranged. The central column 15 facilitates the limitation of the rotating disk 13, ensuring that it can only rotate.

[0024] Working principle: When using it, after determining the direction of the pipeline, you can first install the mounting plate 1 on the wall. If the natural gas pipeline is horizontal, remove the four connecting bolts 10 and take out the upper arc plate 4. After the natural gas pipeline is placed on the lower arc plate 5, tighten the four connecting bolts 10 to fix the natural gas pipeline. The two supporting arc plates 9 can provide auxiliary support. When the natural gas pipeline is pointing upwards, first rotate the adjusting nut 20 to make it spiral upwards on the adjusting stud 19. At this time, the adjusting stud 19 can move downwards. The downward movement of the adjusting stud 19 drives the rotating rod 22 to rotate. The rotation of the rotating rod 22 drives the synchronous rod 18, the two swing rods 7 and the two supporting arc plates 9 to move downwards. The two supporting arc plates 9 separate from the bottom of the lower arc plate 5 until they no longer affect the rotation position of the lower arc plate 5. Then rotate the four limiting bolts 17 to move them out of the four threaded limiting grooves. Then rotate the rotating disk 13 to make the lower arc plate 5 rotate 90 degrees. Then rotate the four limiting bolts 17 in the opposite direction to enter the corresponding four threaded limiting grooves for fixing. After the vertical natural gas pipeline is placed, it can be fixed by the upper arc plate 4. At this time, the side support columns 3 on the upper arc plate 4 and the lower arc plate 5 correspond to the positions of the supporting arc plate 9. Pulling the pulling block 21 causes the adjusting stud 19 to move upward. The movement of the adjusting stud 19 causes the rotating rod 22 to move upward. The movement of the rotating rod 22 causes the synchronous rod 18, the two swing rods 7 and the two supporting arc plates 9 to rotate, so that the two supporting arc plates 9 contact the bottom of the two side support columns 3. Then, rotating the adjusting nut 20 can fix the position of the adjusting stud 19. At this time, the two supporting arc plates 9 can continue to support the upper arc plate 4 and the lower arc plate 5.

[0025] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
