Description

Technical Field

[0001] This utility model relates to the field of auxiliary alignment equipment technology, and in particular to an auxiliary tooling for pipe docking. Background Technology

[0002] As a critical device for transporting fluids, the quality of pipeline installation directly affects system safety and operational efficiency. Among various installation scenarios, the welding and butt jointing of single pipelines and the connection and installation of prefabricated units (such as rows of pipelines or modular pipe sections) are two typical and demanding operations.

[0003] However, achieving precise alignment and reliable fixation of pipelines in these two types of operations presents the following technical challenges: 1. Difficulty in ensuring centering accuracy: The weight of the pipes can easily cause concentricity deviations (misalignment) during connection. Whether it's welded butt joints or assembled flanges and socket connections, this deviation will seriously affect the connection quality and sealing performance. For rows of assembled pipes, ensuring the alignment of the axes of multiple butt joints simultaneously is even more challenging.

[0004] 2. Prone to displacement during construction: During welding (due to thermal stress) or assembly tightening, external forces can easily cause the aligned pipes to shift or deform, disrupting the alignment and requiring repeated adjustments.

[0005] 3. Low operational efficiency: Existing methods often require multiple people to work together or rely on complex tooling, resulting in cumbersome operations, high labor intensity, and low overall efficiency. This problem is particularly prominent in prefabricated installation sites where rapid construction is required.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] To address the aforementioned shortcomings, the purpose of this utility model is to provide an auxiliary tooling for pipe connection, which can be installed and fixed using simple clamps. It can ensure that two clamps can be used for fixing, ensuring that the two joints can be aligned, facilitating subsequent welding, and achieving auxiliary fixing for pipe connection.

[0008] To achieve the above objectives, this utility model provides a pipe docking auxiliary tooling, comprising: at least two clamping fasteners for clamping the pipe, the axes of the two fasteners being coincident; a fixing plate for fixing the fasteners, the fixing plate fixing the positions of the two fasteners and fixing the axes of the two fasteners on the same straight line, wherein when the fasteners fix the pipe, the two pipe joints are aligned and fixed.

[0009] In one embodiment, each of the fasteners includes two opposing semicircular clamps, and both sides of the two semicircular clamps of the same fastener are fixed by a fixing plate.

[0010] In one embodiment, a fixing plate on one side of the semicircular clamp is rotatably connected to a hinge, and two opposing semicircular clamps rotate around the hinge to combine the semicircular clamps to form a fastener for fixing the pipe.

[0011] In one embodiment, the hinge includes: A rotating sleeve fixedly connected to one of the fixed plates; A rotating shaft is fixedly connected to the fixed plate on the same side as the fixed plate. The rotating shaft is rotatably connected inside the rotating sleeve and rotates coaxially with the rotating sleeve.

[0012] In one embodiment, the semi-circular clamp has mounting protrusions on both sides, and fixing holes are provided on the mounting protrusions. The fixing plate is fixed to the mounting protrusions after being inserted into the fixing holes by fixing bolts.

[0013] In one embodiment, a countersunk hole is provided on the inner side of the mounting protrusion, the countersunk hole has a hexagonal cross-section, and the hexagonal part of the fixing bolt is fitted into the inside of the countersunk hole.

[0014] In one embodiment, the semicircular clamp is connected to the fixed plate by welding, and the rotating sleeve and the rotating shaft are fixed to the semicircular clamp by welding.

[0015] In one embodiment, the fixing plate has a plurality of mounting holes, and the fixing holes at the end away from the hinge cooperate to fix two adjacent opposing semi-circular clamps to form a fastener.

[0016] This utility model provides a pipe-connection auxiliary tooling, comprising: at least two clamping fasteners for holding pipes, which center and assist in fixing the pipes to be connected, thereby ensuring better pipe connection. The axes of the two fasteners coincide, ensuring that while the two fasteners externally fix the pipes, the coincidence of their axes also enables the two pipes to be connected to be aligned axially; a fixing plate for fixing the fasteners, which fixes the position of the two fasteners and fixes their axes on the same straight line, ensuring that the fixing plate can simultaneously fix the two fasteners. When the fasteners fix the pipes, the two pipe joints are aligned and fixed, thereby completing the alignment and fixing of the two pipes to be connected and assisting in welding.

[0017] The beneficial effects of this utility model are as follows: Compared with the prior art, the pipe docking auxiliary tooling described in this utility model has the following technical effects: 1. High alignment accuracy: The fixing plate forcibly fixes the axes of the two fasteners on the same straight line, fundamentally ensuring the concentricity of the two pipes to be connected. This effectively solves the problem of inaccurate manual alignment, avoids pipe misalignment and eccentricity, and provides a reliable guarantee for subsequent high-quality welding or assembly connections.

[0018] 2. Effective anti-displacement: The rigid locking formed by the fixing bolts and countersunk hole structure can effectively prevent the pipeline from shifting under the action of welding thermal stress or assembly fastening force, ensuring that the alignment is maintained until the connection is completed.

[0019] 3. Significantly improves work efficiency: The two semi-circular clamps connected by hinges can be opened, closed and locked quickly, simplifying the operation process and reducing the excessive requirements for the number of personnel and skills. The main centering and fixing operations can be completed by a single person, changing the inefficient mode that relies on multiple people to cooperate. It is especially suitable for prefabricated pipeline installation sites that require rapid construction and can greatly shorten the installation time. Attached Figure Description

[0024] See Figure 1 and Figure 2 This utility model provides a pipe-connection auxiliary tooling, which includes: at least two clamping fasteners 6 for holding pipes 3, which center and assist in fixing the pipes 3 to be connected, thereby ensuring better connection of the pipes 3. The axes of the two clamping fasteners 6 coincide, thus ensuring that while the two clamping fasteners 6 externally fix the pipes 3, the two pipes 3 to be connected are aligned by the coincidence of their own axes; and a fixing plate 4 for fixing the clamping fasteners 6. The fixing plate 4 fixes the position of the two clamping fasteners 6 and fixes the axes of the two clamping fasteners 6 on the same straight line. At the same time, it ensures that the fixing plate 4 can fix the position of the clamping fasteners 6, and can fix the two clamping fasteners 6 simultaneously. When the clamping fasteners 6 fix the pipes 3, the two pipes 3 are aligned and fixed, thereby completing the alignment and fixing of the two pipes 3 to be connected and assisted in welding.

[0025] Among them, combined Figure 2 and Figure 3The internal structure of the fastener 6 is designed with an inner hole of the same diameter as the pipe 3 that needs to be fixed, so that the axes of the two pipes 3 that need to be fixed can be aligned by clamping, thereby achieving the effect of auxiliary fixing when the pipes 3 are connected. The fastener 6 and the fixing plate 4 can be fixed by welding or bolting, thereby ensuring the fixing effect between the fixing plate 4 and the fastener 6. The fixing plate 4 is one or more plate-shaped structures with high rigidity. Through its own structural precision, it is ensured that the axes of the two fasteners 4 are coincident / center aligned during manufacturing, thereby structurally forcing the axes of the two fasteners 6 to be on the same straight line.

[0026] In one embodiment, see Figure 3 and Figure 4 To ensure that the pipe 3 can be clamped and connected during use, each fastener 6 includes two opposing semi-circular clamps 63. When the pipe 3 needs to be clamped, the semi-circular clamps 63 are connected to clamp the pipe 3 between the semi-circular clamps 63, thus achieving the normal fixing effect of the pipe 3. Both sides of the two semi-circular clamps 63 of the same fastener are fixed by fixing plates 4. The fixing plates 4 restrict the position of the two semi-circular clamps 63, and at the same time, when the pipe 3 needs to be fixed, the fixing plates 4 restrict the axial position of the semi-circular clamps 63 by force, ensuring the coincidence of the axes of the fastener 6. The fixing plate 4 on one side of the semi-circular clamp 63 is rotatably connected to a hinge. The two opposing semi-circular clamps 63 rotate around the hinge to combine the semi-circular clamps 63 to form the fastener 6 that fixes the pipe 3. By setting the hinge structure, the quick installation of the semi-circular clamps 63 can be achieved, and the disassembly of the semi-circular clamps 63 can be guaranteed.

[0027] In one exemplary implementation, see Figure 1 and Figure 2 The hinges include: A rotating sleeve 1 is fixedly connected to one of the fixed plates 4 to ensure that the fixed plate 4 can rotate synchronously with the rotating sleeve 1, thereby ensuring the normal rotation effect of the two sets of semi-circular clamps 63. The rotating shaft 2 is fixedly connected to the fixed plate 4 on the same side as the fixed plate 4. The rotating shaft 2 is rotatably connected to the inside of the rotating sleeve 1 and rotates coaxially with the rotating sleeve 1, ensuring that the two sets of opposing semi-circular clamps 63 can rotate around the rotating shaft 2 and the rotating sleeve 1, thereby facilitating the docking and fixing of the pipe 3.

[0028] In one embodiment, to ensure the installation and fixation of the fixing plate 4 and the semi-circular clamp 63, mounting protrusions 62 are provided on both sides of the semi-circular clamp 63. Fixing holes are provided on the mounting protrusions 62. The fixing plate 4 is fixed to the mounting protrusions 62 after being inserted into the fixing holes by fixing bolts 5, and is fixed by fixing nuts 7. This ensures that the fixing plate 4 and the mounting protrusions 62 can be detachably connected. The inner side of the mounting protrusions 62 is provided with a countersunk hole 61. The countersunk hole 61 has a hexagonal cross-section. The hexagonal part of the fixing bolt 5 is embedded in the countersunk hole 61 to prevent the hexagonal part of the fixing bolt 5 from interfering with the installation of the semi-circular clamp 63 and affecting the use of the semi-circular clamp 63. By adopting this connection method, the fixing plate 4 can be detachably connected to the semi-circular clamp 63, which is convenient for adjustment.

[0029] In another embodiment, combined Figure 3 and Figure 4 The semi-circular clamp 63 is connected to the fixed plate 4 by welding, which increases the fixing effect between the fixed plate 4 and the semi-circular clamp 63. The rotating sleeve 1 and the rotating shaft 2 are fixed to the semi-circular clamp 63 by welding. The fixed plate 4 has several mounting holes 8. The fixing holes at the end away from the hinge cooperate to fix two adjacent opposing semi-circular clamps 63 to form a clamp 6, thus forming a reliable centering and fixing of the pipe 3.

[0030] In summary, this utility model provides an auxiliary tooling for pipe docking, comprising: at least two clamping fasteners for holding pipes, which center and assist in fixing the pipes to be docked, thereby ensuring better pipe docking. The axes of the two clamping fasteners coincide, ensuring that while the two fasteners externally fix the pipes, the coincidence of their axes allows for the alignment of the two pipes to be docked; a fixing plate for fixing the fasteners, which fixes the position of the two fasteners and fixes their axes on the same straight line, ensuring that the fixing plate can fix the position of the fasteners and that the two fasteners can be fixed simultaneously. When the fasteners fix the pipes, the two pipe joints are aligned and fixed, thereby completing the alignment and fixing of the two pipes to be docked and assisting in welding. In summary, the technical effect of this utility model is that by installing and fixing simple clamps, it ensures that the two joints can be fixed by two clamps, ensuring alignment of the two joints, facilitating subsequent welding, and achieving auxiliary fixing for pipe docking.
