Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, specifically a pipeline joint splicing device. Background Technology

[0002] Pipe splicing is a crucial step in the construction and installation of pipelines. After the initial laying of the pipeline is completed, rubber plugs need to be inserted at both ends of the pipeline to prevent foreign objects from entering the pipeline. However, if the rubber plugs at both ends of the pipeline are removed too early during the pipeline splicing process, it will increase the risk of foreign objects entering the pipeline during the pipeline connection. On the other hand, if the rubber plugs at both ends of the pipeline are removed when two adjacent pipelines are close together, the limited operating space will increase the difficulty of removing the rubber plugs at both ends of the pipeline.

[0003] Therefore, there is an urgent need for a pipe splicing device to solve the above problems. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] Example 1

[0021] Please see Figures 1-5 The pipe splicing device shown in the figure includes a movable base plate 101 and two height adjustment mechanisms 102 arranged symmetrically on one side of the movable base plate 101. The two height adjustment mechanisms 102 are provided with a mounting plate 103 on the side away from the movable base plate 101. It also includes a splicing component provided on the mounting plate 103 for splicing two adjacent pipes.

[0022] There are two splicing components, which are symmetrically arranged. The mounting plate 103 is provided with a driving component for driving the two splicing components. The splicing component includes a T-shaped support plate 201 slidably connected to the side of the mounting plate 103 away from the movable base plate 101. A first splicing ring 202 is fixedly connected to one end of the T-shaped support plate 201 away from the mounting plate 103. A second splicing ring 203 is hinged to the side of the first splicing ring 202 away from the T-shaped support plate 201. Ear plates are fixedly connected to the side of the first splicing ring 202 and the second splicing ring 203 away from the hinge end. The two ear plates are fixed together by bolts and nuts. The first splicing ring 202 and the second splicing ring 203 are provided with a sealing component for sealing the pipe opening during the splicing process and a fixing component for fixing the pipe during the splicing process.

[0023] It should be noted that by setting up the splicing components, while achieving the splicing of adjacent pipes, the sealing components are used to seal the openings of the two spliced ​​pipes. This reduces the risk of foreign objects entering the pipes during the splicing process and makes it easier to remove the sealant from the pipe openings, thereby improving the sealing line and convenience of the pipe splicing.

[0024] It is worth noting that the height adjustment mechanism 102 includes, but is not limited to, cylinders, push rod motors or lead screws. As these are existing, mature and widely used technologies, they will not be described in detail here.

[0025] Please see Figure 2 and Figure 4 The sealing assembly shown in the figure includes a first sealing ring 301 and a second sealing ring 302 that are slidably connected to the side of the first splicing ring 202 and the second splicing ring 203 away from the pipe. The first splicing ring 202 and the second splicing ring 203 are respectively provided with telescopic components for telescopic extension and retraction of the first splicing ring 202 and the second splicing ring 203. A plug-in ring 305 is fixedly connected to the side of the first sealing ring 301 away from the first splicing ring 202. A sealing plate 303 is plugged into the plug-in ring 305. A handle 304 is fixedly connected to the side of the sealing plate 303 away from the mounting plate 103.

[0026] It should be noted here that the sealing components are used to seal the pipe openings, thereby reducing the risk of foreign objects entering the pipe interior during the splicing of adjacent pipes.

[0027] Please see Figure 2 and Figure 4 The telescopic assembly shown in the figure includes a plurality of T-shaped rods 401 arranged in a ring array and slidably connected to the first splicing ring 202. One end of each T-shaped rod 401 is connected to the first sealing ring 301. A spring 402 is sleeved on the side wall of each T-shaped rod 401. The two ends of each spring 402 are respectively connected to the side wall of the T-shaped rod 401 and the first splicing ring 202.

[0028] It should be noted here that the telescopic component is designed to provide elastic force to the sealing plate 303, thereby allowing the sealing plate 303 to fully abut against the pipe opening.

[0029] Working principle: When splicing two adjacent pipes, firstly, the movable base plate 101 is moved to the opposite side of the two adjacent pipes. Then, the two height adjustment mechanisms 102 are used to push the mounting plate 103 closer to the pipe. After the two first splicing rings 202 on one side of the mounting plate 103 are moved to a suitable height, the height adjustment mechanism 102 is stopped. Then, the second splicing ring 203 is rotated so that the second splicing ring 203 is fitted onto the side wall of the pipe. One end of the first splicing ring 202 and the second splicing ring 203 are locked and fixed by bolts and nuts.

[0030] After the first splicing ring 202 and the second splicing ring 203 are fitted onto the side wall of the pipe, the two T-shaped support plates 201 are moved by the drive assembly, so that the two sealing plates 303 abut against the pipe opening. After the two sealing plates 303 abut against the pipe opening, the pipe can be fixed by the fixing assembly. After the pipe is fixed, the drive assembly is used again to drive the two T-shaped support plates 201 to move closer to each other, thereby driving the two pipes to move closer to each other.

[0031] As the two pipes approach each other, when the sidewalls of the insertion rings 305 on one side of the two sealing plates 303 are fully abutted, the movement of the two T-shaped support plates 201 stops. At this point, the distance between the pipe openings of the two adjacent pipes has been reduced to a smaller gap. Therefore, the sealing plate 303 can be moved out of the insertion ring 305 by pulling the handle 304. After the sealing plate 303 is moved out, the driving component can be used to push the two adjacent pipes closer together again until the end faces of the two adjacent pipes abut each other, thus completing the splicing of the adjacent pipes. The two sealing plates 303 seal the pipe openings of the two pipes being spliced, reducing the risk of foreign objects entering the pipes during the splicing of adjacent pipes. At the same time, it is easy to remove the sealing plate 303 from the pipe openings, thereby improving the sealing line and convenience of the splicing of pipes.

[0032] Example 2

[0033] Please see Figure 3This embodiment further illustrates Example 1. The driving assembly shown in the figure includes three equally spaced driving holes 501 on the side of the mounting plate 103 near the T-shaped support plate 201. Two of the three driving holes 501 on the side are respectively fixedly connected to driving rods 502. Two first driving plates 503 are slidably connected to the two driving rods 502. The two first driving plates 503 on the same vertical side are connected to the T-shaped support plate 201. A double-threaded rod 504 is rotatably connected to the middle of the three driving holes 501. Two second driving plates 505 are threadedly connected to the side wall of the double-threaded rod 504. The two second driving plates 505 are respectively connected to the two T-shaped support plates 201. A motor 507 is fixedly connected to one side of the mounting plate 103. The output end of the motor 507 is connected to the double-threaded rod 504.

[0034] It should be noted here that: through the setting of the drive component, the motor 507 drives the double-ended threaded rod 504 to rotate, and then under the threaded meshing transmission action of the double-ended threaded rod 504 and the two second drive plates 505 and the guiding action of the two first drive plates 503, the two T-shaped support plates 201 are driven to move closer to each other or further away from each other.

[0035] It is worth noting that the double-threaded rod 504 refers to a threaded bar with two threads having opposite directions of rotation on its side wall. Therefore, the two second drive plates 505 are screwed to the threaded bars with different directions of rotation.

[0036] Example 3

[0037] Please see Figure 5 This embodiment further illustrates other embodiments. The fixing component shown in the figure includes a plurality of fixing rods 601 slidably connected to the first splicing ring 202. The fixing rods 601 are arranged in a circular array. An arc-shaped clamping plate 602 is fixedly connected to the side of each fixing rod 601 near the pipe. A plurality of push rod motors 603 are fixedly connected to the side of the first splicing ring 202 away from the arc-shaped clamping plate 602. The output end of each push rod motor 603 is connected to each fixing rod 601 respectively.

[0038] It should be noted here that: by setting up the fixing components, the synchronous push of multiple push rod motors 603 causes the arc-shaped clamps 602 to move closer to each other, thereby achieving concentric fixing of the pipes, so that the two adjacent pipes are in the same position, which facilitates the splicing of the two adjacent pipes.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
