[0002] Flange-connected instruments are widely used in industrial production. During maintenance work, the instruments often need to be removed for inspection and testing. Due to the coking phenomenon caused by the production of catalytic cracking units, it is very difficult to remove the wear-resistant thermocouples. Some instrument equipment operates in an environment with viscous media for a long time, making it difficult to remove the instrument equipment. Irregular removal of instrument equipment often causes damage to the instrument equipment.

[0003] The flange head of the underwater data center is heavy, has a high positioning center of gravity, and requires a large number of installation bolts. During the existing maintenance and disassembly of the data center, the positioning of the flange head and the removal or installation of all bolts take up a long time using cranes and other lifting equipment, increasing maintenance costs.

[0039] Example

[0040] This embodiment provides a flange auxiliary installation tool, such as Figures 1 to 3 As shown, the working environment is underwater, and the working target is a sealing flange. The sealing flange includes a flange head 3 and a manhole pipe 4 , and the manhole pipe 4 is fixed on the flange head 3 .

[0041] like Figures 1 to 3 As shown, the flange auxiliary installation tooling includes an adjustment structure 1 and a limiting bracket structure 2. The limiting bracket structure 2 includes a first frame 11, a second frame 12 and an adjustment fixture 13. The first frame 11 is a lower frame, which is placed on a base. The base can be the ground or other base that can support the first frame 11, which is not specifically limited here. The second frame 12 is arranged above the first frame 11, and an adjustment fixture 13 is fixed between the first frame 11 and the second frame 12 brackets. The adjustment fixture 13 is an adjusting nut. The top end of the adjustment fixture 13 is fixed on the lower surface of the second frame 12, and the bottom end of the adjustment fixture 13 is fixed on the top surface of the first frame 11. Specifically, there are several adjustment fixtures 13. In this embodiment, there are specifically six. Three are provided on each side of the area between the first frame 11 and the second frame 12; the three adjustment fixtures 13 on the same side are arranged at intervals.

[0042] like Figure 2As shown, a first limiting bracket 21, a second limiting bracket 22 and a counterweight 6 are sequentially arranged above the second frame 12, and the first limiting bracket 21 and the second limiting bracket 22 can be detachably mounted on the second frame 12. A mounting groove is provided on one side of the second frame 12 where the first limiting bracket 21 is mounted, and the mounting groove can effectively avoid interference between the lower end of the flange head 3 and the second frame 12. There are two first limiting brackets 21, and the two first limiting brackets 21 are respectively arranged on both sides of the mounting groove, and the two first limiting brackets 21 are both provided with a first limiting groove 211. The second limiting bracket 22 is arranged in the middle part of the second frame 12, and a second limiting groove 221 is provided on the upper end of the second limiting bracket 22. Among them, the first limiting groove 211 and the second limiting groove 221 are respectively arranged as arc grooves corresponding to the flange head 3 and the manhole pipe 4. As shown Figure 1 As shown, the counterweight 6 is arranged on the side of the adjustment structure 1 away from the first limit bracket 21. Specifically, according to the weight and center of gravity of the flange head 3, the first limit bracket 21, the second limit bracket 22, the first frame 11 and the second frame 12, the counterweight 6 is placed on the side of the upper surface of the second frame 12 away from the first limit bracket 21, and the center of gravity of the entire device is adjusted to the center of the second frame 12 to prevent rollover due to eccentricity. The counterweight can be a precast concrete block, a water tank or other steel components.

[0043] When the flange needs to be installed, first place the assembled adjustment structure 1 at the position where the flange needs to be installed, place the first frame 11 on the base, adjust the upper frame to the correct installation position of the flange head 3 with the help of a jack, and then tighten the adjustment fixture 13 to fix the second frame 12 and the first frame 11. It is not only necessary to adjust the height of the second frame 12 to meet the installation requirements and to the correct installation position, but also to ensure that the placement angle of the second frame 12 is horizontal regardless of whether the placement angle of the first frame 11 is tilted. For example: when the base is higher on the left side and lower on the right side, the adjustment fixture 13 on the left side can be shortened and the adjustment fixture 13 on the right side can be lengthened. This makes the second frame 12 tend to be horizontal. Using the above method, the levelness of the site is not high, and it can also be applied to sites with poor levelness.

[0044] There are two installation schemes at this time. The first one is to fix the first limiting bracket 21 on both sides of the installation groove, and fix the second limiting bracket 22 on the corresponding manhole pipe 4 between the first limiting bracket 21 and the counterweight 6. At this time, the axis corresponding to the arc groove surface of the first limiting groove 211 on the first limiting bracket 21 is collinear with the axis corresponding to the arc groove surface of the second limiting groove 221, and the above axis is collinear with the axis of the pipe to be installed with the flange. The flange head 3 is mounted on the limiting bracket structure 2 corresponding to the first limiting groove 211 and the manhole pipe 4 is mounted on the second limiting groove 221, and then the flange is installed in a translation manner. The second one is to first tighten the flange head 3 in the appropriate place according to the position of the second frame 12 and the flange head 3, and then tighten them in the appropriate place according to the position of the second frame 12 and the manhole flange pipe, and then use bolts to connect the first limiting bracket 21 and the second limiting bracket 22 to the second frame 12.

[0045] In order to ensure the stability of the installation, the manhole pipe 4 can also be fixed to the second limiting bracket 22 by a clamp 5 to ensure the stability of the installation. Specifically, the clamp 5 is sleeved on the manhole pipe 4 from top to bottom, and its two ends are respectively fixed to the two ends of the second limiting groove 221 to fix the manhole pipe 4 between the second limiting groove 221 and the clamp 5.

[0046] The above solution can be used as a storage bracket for the flange head 3, eliminating the need to remove and then flip the flange head 3 for storage. Furthermore, for maintenance, the flange head 3 only needs to be fixed during disassembly and then reassembled. During installation, the flange head 3 does not need to be repositioned, and can be directly moved to the disassembly position for alignment, reducing positioning time during maintenance. Furthermore, the crane usage time can be reduced, and the flange head 3 can be reused as a maintenance tool, reducing usage costs.

[0047] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
