Description

Technical Field

[0001] This utility model relates to the technical field of pipe alignment, and in particular to a pipe alignment device. Background Technology

[0002] Pipe connection refers to the process of connecting prefabricated pipe sections into a complete system according to the design drawings. During construction, different connection methods should be selected based on the material of the pipes used. Common steel pipes can be connected using methods such as threaded connections, flange connections, welding connections, socket connections, and pipe adhesive connections.

[0003] Currently, when connecting pipes, it is necessary to align the two pipes. However, this is usually done manually by workers, especially in pipe repair work where it is impossible to carry large connecting tools. Manual connection can only be performed on-site. However, this method is not only cumbersome, but also lacks precision. Therefore, a pipe alignment device has been designed that is not only easy to carry, but also facilitates precise pipe connection by workers. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a pipe alignment device.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A pipe fitting device, characterized in that it comprises: a pipe fixing ring and a pipe; the pipe fixing ring includes two movable half-rings, and two hollow columns are provided on the ring body of the two movable half-rings on the side away from each other, and threaded columns are provided in the hollow columns, and a rubber pressure plate is provided on the side of the threaded columns near the inner ring of the pipe fixing ring; limiting guide posts are passed through the plates of the top and bottom of the two movable half-rings on the side close to each other, and a hollow ring is provided on the ring body of the movable half-rings on the side away from each other, and a guide post is movably inserted into the ring body of the hollow ring; pipe fixing rings are sleeved on both ends of the pipe body connection.

[0007] In one embodiment, the two hollow columns are designed symmetrically with the center of the movable half-ring as the center. The threaded groove in the inner cavity of the hollow column extends to the ring body of the movable half-ring, and the diameter of its side surface matches the diameter of the threaded column side surface.

[0008] In one embodiment, a rotating handle is fixedly connected to the side of the threaded post away from the movable semi-ring, and a connecting shaft is rotatably connected to the position where the threaded post and the rubber pressure plate are connected via a bearing.

[0009] In one embodiment, the two movable semi-rings in the pipe retaining ring are combined together, and the diameter of their front faces is larger than the diameter of the front faces of the pipe.

[0010] In one embodiment, the top and bottom blocks on the side of the movable semi-rings that are close to each other extend away from the movable semi-rings, and the limiting guide post passes through the extended block. The limiting guide post is composed of a threaded insert and a connecting post that are threadedly connected together.

[0011] In one embodiment, the two ends of the guide post pass through the hollow rings of the two pipe fixing rings on the pipe break.

[0012] In one embodiment, the two rings of the hollow ring are designed in a symmetrical mirror shape with the center of the movable semi-ring as the midpoint.

[0013] In one embodiment, the side of the rubber pressure plate closest to the pipe is set as an arc-shaped surface, and the side of the rubber pressure plate closest to the threaded post is designed as an iron plate.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] This utility model discloses a pipe alignment device. Through the design of two movable semi-rings and limiting guide posts, the two movable semi-rings can be detached and fitted near the two pipe openings. Combined with the threaded posts and rubber pressure plates designed inside the movable semi-rings, the four rubber pressure plates within the two movable semi-rings can abut the pipes from four directions, thereby fixing and limiting the two pipes to be connected. Furthermore, the structural design of the hollow rings and guide posts allows for precise alignment of the two fixed pipes. This achieves the goal of not only being easy to carry but also facilitating precise pipe connection by workers. Attached Figure Description

[0016] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope.

[0017] Figure 1 This is a schematic diagram of the overall structure of the pipe fixing ring of this utility model;

[0018] Figure 2 This is a schematic diagram of the pipe connection of this utility model.

[0019] In the diagram: 1. Pipe fixing ring; 11. Movable half ring; 12. Threaded post; 13. Rotating handle; 14. Rubber pressure plate; 15. Hollow ring; 16. Restricting guide post; 17. Connecting shaft; 18. Hollow post; 2. Pipe; 3. Guide post. Detailed Implementation

[0020] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0021] like Figure 1-2 As shown, a pipe fitting device includes: a pipe fixing ring 1 and a pipe 2; the pipe fixing ring 1 includes two movable half-rings 11, and two hollow columns 18 are provided on the ring body on the side of the two movable half-rings 11 that are far apart from each other. A threaded column 12 is provided in the hollow column 18, and a rubber pressure plate 14 is provided on the side of the threaded column 12 near the inner ring of the pipe fixing ring 1; a limiting guide post 16 passes through the plate body at the top and bottom of the side of the two movable half-rings 11 that are close to each other, and a hollow ring 15 is provided on the ring body on the side of the movable half-rings 11 that are far apart from each other. A guide post 3 is movably inserted into the ring body of the hollow ring 15; the pipe fixing ring 1 is sleeved on both ends of the connection of the pipe body of the pipe 2. It should be noted that when pipe connection is required, the staff first removes the two pipe fixing rings 1 and puts them on the two pipes that need to be connected (the two pipes are S1 and S2 respectively). After that, by rotating the handle 13, the threaded post 12 moves closer to the pipe 2, thereby moving the rubber pressure plate 14 closer to the pipe 2. This allows the four rubber pressure plates 14 to fix the pipe fixing rings 1 from four directions. At this time, it is only necessary to push S2 along the guide post 3 in the hollow post 18 towards S1 to complete the connection of the two pipes 2.

[0022] like Figure 1-2 As shown in one embodiment, the two hollow columns 18 are designed symmetrically with the center of the movable half-ring 11 as the center. The threaded groove in the inner cavity of the hollow column 18 extends to the ring of the movable half-ring 11, and the diameter of its side surface matches the diameter of the side surface of the threaded column 12. It should be noted that the hollow column 18 and the movable half-ring 11 are designed as an integrated structure, thereby enhancing their overall strength.

[0023] like Figure 1-2 As shown in one embodiment, a rotating handle 13 is fixedly connected to the side of the threaded post 12 away from the movable semi-ring 11, and a connecting shaft 17 is rotatably connected to the position where the threaded post 12 and the rubber pressure plate 14 are connected via a bearing. It should be noted that the design of the rotating handle 13 allows the user to easily rotate the threaded post 12 by hand.

[0024] like Figure 1-2As shown in one embodiment, the two movable semi-rings 11 in the pipe fixing ring 1 are combined together, and the diameter of their front faces is larger than the diameter of the front faces of the pipe 2. It should be noted that the diameter of the pipe fixing ring 1 is not fixed and can be designed with different diameters to accommodate pipes of different diameters.

[0025] like Figure 1-2 As shown in one embodiment, the top and bottom blocks of the movable half-rings 11, located close to each other, extend away from the ring body of the movable half-rings 11. A limiting guide post 16 passes through this extended block. The limiting guide post 16 is composed of a threaded insert and a connecting post that are inserted into and threaded together. It should be noted that this design allows workers to easily separate the two movable half-rings 11 and fit them onto the pipe.

[0026] like Figure 1-2 As shown in one embodiment, the two ends of the guide post 3 pass through the hollow rings 15 of the two pipe fixing rings 1 on the break of the pipe 2, respectively. It should be noted that the guide post 3 can be removed from the hollow rings 15 as needed for docking to achieve precise positioning.

[0027] like Figure 1-2 As shown in one embodiment, the two rings of the hollow ring 15 are designed in a symmetrical mirror shape with the center of the movable semi-ring 11 as the midpoint. The side of the rubber pressure plate 14 closest to the pipe 2 is set as an arc surface, and the side of the rubber pressure plate 14 closest to the threaded post 12 is designed as an iron plate. It should be noted that this design can enhance the fixing effect on the pipe 2.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
