Description

Technical Field

[0001] The utility model relates to the field of pipeline laying, in particular to a pipeline docking and positioning mechanism for natural gas construction. Background Art

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere and lithosphere (including oilfield gas, gas field gas, mud volcano gas, coalbed methane and biogas, etc.). Natural gas is a high-quality fuel and chemical raw material. The main use of natural gas is as fuel. It can be used to produce carbon black, chemicals and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry. Existing natural gas is usually transported by pipelines. Pipelines can effectively isolate natural gas from the surrounding environment, reduce the risk of leakage or explosion, and ensure the safe transportation of natural gas.

[0003] For example, the utility model patent with publication number CN214331682U and publication date October 1, 2021, discloses a docking device for natural gas pipeline installation, including a base plate, a slide groove is opened in the middle of the upper side wall of the base plate, and sliders are movably connected at both ends of the slide groove, and the upper ends of the two groups of sliders are fixedly installed with fixing mechanisms. The utility model is implemented by fixing the upper ends of the sliders movably installed on the upper side wall of the base plate with fixing mechanisms fixedly installed, and the first screw connected by screwing through the first screw hole in the middle of the first clamping seat at the upper end of the fixing mechanism is fixedly connected to the central axis of the first bearing fixedly installed in the middle of the upper end of the clamping block. When the two groups of natural gas pipelines to be docked are first fixed in the inner circular grooves of the two groups of fixing mechanisms, the first screw is then rotated to make the clamping block firmly fix the two groups of natural gas pipelines. Finally, one group of natural gas pipelines can be docked with the other group by moving it. The structure is simple and the operation is convenient, which is conducive to more practical use of the docking device for natural gas pipeline installation.

[0004] When existing natural gas pipelines are docked, flanges are usually connected to the butt ends of the two pipelines, and then the flanges at the butt ends of the two pipelines are connected to complete the docking of the two pipelines. The existing flanges are connected by bolts. However, when using bolts to connect the two flanges, it is usually necessary to manually adjust the positions of the two flanges to align the connection holes on the two flanges. Manual fine-tuning of the pipeline position is time-consuming and laborious. Utility Model Content

[0028] In order to make those skilled in the art better understand the technical solution of the present invention, Figure 1-7 , the utility model is further introduced in detail.

[0029] In each embodiment of the present invention, for the convenience of description and understanding, the axial direction of the pipe 4 is called the length direction, the direction perpendicular to the length direction on the horizontal plane is called the width direction, and the gravity direction is called the vertical direction, that is, the length direction, width direction and vertical direction constitute a three-dimensional rectangular coordinate system.

[0030] An embodiment of the present utility model provides a pipeline docking and positioning mechanism for natural gas construction, including a docking platform 1 and a driving component 2. Two groups of docking components 3 are slidably arranged on the docking platform 1, and pipelines 4 are placed on the two docking components 3. Flange parts 5 are installed at the adjacent ends of the two groups of pipelines 4. The driving component 2 is used to drive the two groups of docking components 3 to move the pipelines 4 closer to or away from each other, and also includes an adjustment component 6. The adjustment component 6 is installed on one of the docking components 3; when the two docking components 3 are close to each other, the adjustment component 6 fine-tunes the placement angle of the pipeline 4.

[0031] Specifically, the docking platform 1 is placed horizontally on the ground, wherein the driving component 2 can be selected from two electrically controlled telescopic rods, the telescopic ends of the two electrically controlled telescopic rods are respectively connected to the two docking components 3, and the docking component 3 can be selected from a support bracket, which is used to place the pipe 4. When the two pipes 4 need to be docked, the two electrically controlled telescopic rods respectively drive the corresponding docking components 3 to approach each other, and the two docking components 3 bring the two pipes 4 close to each other, and the flange parts 5 of the two pipes 4 are docked. Then, the two flange parts 5 are connected together using bolts manually or mechanically to complete the docking process of the two pipes 4.

[0032] Obviously, when the two pipes 4 need to be docked, the holes for connection on the flange parts 5 on the two pipes 4 need to be aligned. However, when the pipes 4 are placed on the docking assembly 3, the holes for connection on the flange parts 5 on the two pipes 4 are not always aligned. That is, before the two pipes 4 are docked, they need to be manually adjusted so that the holes for connection on the flange parts 5 on the two pipes 4 are aligned, which increases the workload of the staff.

[0033] In order to solve the above problems, in this embodiment, an adjustment component 6 is provided, and the adjustment component 6 is used to adjust the placement state of one of the pipes 4, so that the flange portion 5 on the pipe 4 is aligned with the hole position for connection on the flange portion 5 on the other pipe 4, wherein the adjustment component 6 is installed on one of the docking components 3. When the two electrically controlled telescopic rods drive the two docking components 3 close to each other, the adjustment component 6 on the docking component 3 rotates with the corresponding pipe 4 (the pipe 4 rotates around its own axis), so that the hole positions for connection on the flange portions 5 on the two pipes 4 are aligned when docking. Subsequently, the staff uses bolts to connect the flange portions 5 on the two pipes 4 together to complete the connection processing of the pipes 4.

[0034] Preferably, a guide slot 11 is provided on the docking platform 1 , and both docking components 3 are slidably installed in the guide slot 11 . The driving component 2 is used to drive the two docking components 3 to slide relative to each other along the guide slot 11 .

[0035] Specifically, by setting a guide groove 11 on the docking platform 1, the guide groove 11 restricts the movement of the docking component 3, that is, when the driving component 2 drives the docking component 3 to move, the docking component 3 slides along the groove of the guide groove 11, ensuring that the docking component 3 can carry the pipe 4 for docking, avoiding the pipe 4 from being misplaced during movement.

[0036] Preferably, the docking assembly 3 includes a supporting platform 31 , on which are mounted a plurality of locking members 32 , which are spaced apart along the length direction. The locking members 32 are used to limit the sliding of the pipe 4 in the length direction.

[0037] Specifically, the locking member 32 includes a locking clamp 321, one end of which is rotatably mounted on the supporting platform 31, a first rotation groove 322 is provided on the inner wall of the locking clamp 321, and a second rotation groove 323 is provided on the supporting platform 31. When the locking clamp 321 is stuck on the supporting platform 31 (that is, the locking clamp 321 fixes the pipe 4 on the supporting platform 31), the first rotation groove 322 and the second rotation groove 323 are coaxial, and a plurality of adsorption electromagnetic blocks 324 are slidably installed inside the first rotation groove 322 and the second rotation groove 323, and the plurality of adsorption electromagnetic blocks 324 are arranged at intervals along the circumference of the pipe 4.

[0038] When the pipe 4 is placed on the supporting platform 31 manually or by mechanical equipment, the locking clamp 321 is manually connected to the supporting platform 31. At this time, the first rotating groove 322 on the inner wall of the locking clamp 321 is connected to the second rotating groove 323 on the supporting platform 31. The adsorption electromagnetic block 324 in the first rotating groove 322 and the second rotating groove 323 adsorbs the pipe 4. The adsorption electromagnetic block 324 restricts the movement of the pipe 4 along the length direction. However, because the adsorption electromagnetic block 324 can rotate in the first rotating groove 322 and the second rotating groove 323, the pipe 4 can now rotate around its own axis, which is convenient for adjusting the connection holes on the flange parts 5 at the ends of the two pipes 4 for alignment.

[0039] It should be noted that the flange portion 5 includes a first flange member 51 and a second flange member 52. The first flange member 51 and the second flange member 52 are respectively installed at the adjacent ends of the two pipes 4. The first flange member 51 and the second flange member 52 are both provided with a plurality of connecting holes 53. The plurality of connecting holes 53 are arranged at intervals along the circumference of the first flange member 51 or the second flange member 52. The first flange member 51 and the second flange member 52 are connected by bolts.

[0040] Among them, a avoidance hole 21 is opened on the docking component 3; the adjustment component 6 includes an adjustment rod 61 slidably installed in the avoidance hole 21, and the adjustment rod 61 is connected to the avoidance hole 21 through a first spring 62, and the end of the adjustment rod 61 away from the first spring 62 is arc-shaped.

[0041] Specifically, the avoidance hole 21 is provided on the supporting platform 31, and in order to facilitate the insertion of the adjustment rod 61 into the connection hole 53 on the corresponding flange portion 5, in this embodiment, the head of the adjustment rod 61 is arc-shaped. When the staff place the two pipes 4 on the two docking components 3 respectively, they manually adjust the positions of the two pipes 4 so that the connection holes 53 on the flange portions 5 of the two pipes 4 are initially aligned (at this time, they are only approximately aligned, not really aligned), so that the adjustment rod 61 passes through the connection hole 53 of the flange portion 5 on one of the pipes 4, and then the drive component 2 is driven. Drive the two docking assemblies 3 closer to each other, and the two docking assemblies 3 bring the two pipes 4 closer to each other. At this time, the arc-shaped head of the adjustment rod 61 passes through the connection hole 53 of the flange part 5 on the other pipe 4, so that the connection holes 53 of the flange parts 5 on the two pipes 4 are in an aligned state. As the two docking assemblies 3 gradually approach each other, the adjustment rod 61 always passes through the connection holes 53 of the flange parts 5 on the two pipes 4, completing the positioning processing when the two pipes 4 are docked. Then, the flange parts 5 of the two pipes 4 are manually connected together by bolts to complete the processing of connecting the pipes 4.

[0042] Preferably, a plurality of adjustment assemblies 6 are provided, and the plurality of adjustment assemblies 6 correspond one-to-one to the connection holes 53 on the first flange 51 .

[0043] Specifically, by setting up multiple adjustment components 6, when the first flange component 51 and the second flange component 52 are docked, the multiple adjustment components 6 simultaneously pass through the multiple connection holes 53 on the second flange component 52. At this time, when the pipe 4 connected to the second flange component 52 needs to be rotated to adjust the position, the adjustment rods 61 in the multiple adjustment components 6 work together to rotate the pipe 4. Compared with setting up one adjustment rod 61, when multiple adjustment rods 61 drive the pipe 4 to rotate, the single adjustment rod 61 receives less force, thereby extending the service life of the adjustment rod 61. In addition, setting up multiple adjustment rods 61 can improve the docking accuracy of the first flange component 51 and the second flange component 52 when docking, and ensure that the connection holes 53 on the first flange component 51 and the second flange component 52 are in an aligned state.

[0044] Preferably, two locking blocks 22 are provided in the avoidance hole 21 . The two locking blocks 22 are spaced apart to form a locking groove 23 . The locking groove 23 is used to adjust the component 6 and limit the contraction of the first spring 62 .

[0045] Specifically, the adjustment rod 61 includes a fixed section 611 and a rotating section 612. One end of the fixed section 611 is connected to the avoidance hole 21 through the first spring 62. The other end of the fixed section 611 is rotatably installed with the rotating section 612. A locking block 613 is fixedly installed on the side wall of the rotating section 612 close to the fixed section 611. The locking block 613 is opposite to the locking groove 23. When the rotating section 612 rotates, the locking block 613 enters the locking groove 23, thereby limiting the contraction of the first spring 62.

[0046] When the first and second flange members 51 and 52 are connected, the first spring 62 is unlocked, and the first spring 62 is driven to contract, so that the adjustment rod 61 leaves the connection hole 53 on the first flange member 51 and the second flange member 52, completing the disassembly of the adjustment rod 61.

[0047] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
