[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] As Figure 1 and Figure 2 shown, the utility model provides a kind of for flange butt joint auxiliary device, including first clamp 1 and second clamp 2, the first clamp 1 and second clamp 2 are respectively covered on first flange 3 and second flange 4, butt joint fastening assembly for the center alignment of first flange 3 and second flange 4 is equipped between the first clamp 1 and second clamp 2, leveling piece is equipped on the first clamp 1 and second clamp 2, and the leveling piece is used to adjust the parallelism of first flange 3 and second flange 4, so that the contact surface of first flange 3 and second flange 4 is closely contacted.This auxiliary device makes the flange between different skids keep coaxial alignment and closely contact by mechanical control, greatly reduces the difficulty of butt joint, increases the installation precision of flange butt joint, improves the efficiency of station construction.

[0024] In the embodiment, the first clamp 1 and the second clamp 2 are each composed of two half-ring-shaped clamp bodies 12, and the two clamp bodies 12 realize opening and closing functions through a hinged structure. Specifically, one end of the two clamp bodies 12 forms a hinged structure through a pin shaft 13, and the other end is provided with a protruding connecting piece 14, which is fixed through a bolt assembly. The bolt assembly includes a fastening screw 16 and a fastening nut 17, and the connecting piece 14 is provided with a bolt hole 15. After the fastening screw 16 passes through the bolt hole 15, one fastening nut 17 is installed at each of the upper and lower ends of the fastening screw 16, and the clamp body 12 is fixed by tightening the nuts. The first clamp 1 and the second clamp 2 are provided with a ring-shaped groove 11 on the inner wall, and after the fastening nuts 17 are tightened, the first flange 3 and the second flange 4 can be firmly nested inside.

[0025] In this embodiment, the first clamp 1 and the second clamp 2 are connected as a whole by a docking fastening assembly. Multiple docking fastening assemblies are provided and evenly distributed circumferentially around the first clamp 1 and the second clamp 2. The docking fastening assembly includes a tension bolt 5 and a tension nut 6. Bolt holes 15 are provided on the clamp body 12 of the first clamp 1 and the second clamp 2. After the first clamp 1 and the second clamp 2 are installed, the tension bolt 5 and the tension nut 6 are installed through the bolt holes 15 on the clamp body 12 to ensure that the first flange 3 and the second flange 4 are aligned, thus achieving smooth docking of the pipeline 8.

[0026] In this embodiment, the leveling component is a leveling bolt 7, with three leveling bolts 7 evenly distributed circumferentially on the first clamp 1 and the second clamp 2. The leveling bolts 7 are installed on the clamp body 12 of the first clamp 1 and the second clamp 2, and their axial direction is perpendicular to the flange faces of the first flange 3 and the second flange 4. Due to precision errors in actual processing, the mating surfaces of the first flange 3 and the second flange 4 often cannot be perfectly flush, directly affecting the flange mating accuracy. By using this mating aid, after the first clamp 1 and the second clamp 2 are installed and aligned by the tension bolts 5 and tension nuts 6, tightening the leveling bolts 7 can apply pressure perpendicular to the flange faces of the first flange 3 and the second flange 4, forcing the contact surfaces of the first flange 3 and the second flange 4 to make tight contact, greatly reducing the difficulty of flange mating, increasing the accuracy of flange mating, and improving the efficiency of station construction.

[0027] In this embodiment, as Figure 2 As shown, the specific construction process of the flange docking auxiliary device is as follows: First, the first clamp 1 and the second clamp 2 are nested on the first flange 3 and the second flange 4 to be docked, respectively. The flanges are fixed by the fastening screw 16 and the fastening nut 17. Then, the tension bolt 5 and the tension nut 6 are installed between the first clamp 1 and the second clamp 2. By tightening the tension nut 6, the centers of the first flange 3 and the second flange 4 are forced to align. Finally, the leveling bolt 7 is adjusted to ensure that the contact surfaces of the first flange 3 and the second flange 4 are in close contact, increasing the accuracy of the flange docking and improving the efficiency of the flange docking. After the flange docking is completed, the leveling bolt 7, the tension nut 6, and the fastening nut 17 are loosened, and the first clamp 1 and the second clamp 2 are removed, ready for docking of the next set of flanges.

[0028] In this embodiment, by using a flange docking aid, the docking of flanges between different skids is transformed from manual control to mechanical control, significantly reducing the docking difficulty and improving docking accuracy and efficiency. Furthermore, mechanical alignment ensures that the flanges remain coaxially aligned and in close contact, avoiding potential damage to the flange plates or pipes 8 that might occur during manual force docking, thus greatly enhancing the safety of the site.
