Description

Technical Field

[0001] This utility model relates to the field of flange mating adjustment equipment, and more specifically, to a flange misalignment adjustment tool. Background Technology

[0002] Currently, flanges are used to connect pipes to transport fluids. However, after a period of use, the flanges need to be removed for pipe maintenance.

[0003] After pipeline maintenance is completed, the flanges need to be reconnected. However, misalignment of the flanges or the flange threaded holes can easily occur at this time. Specifically, the causes of misalignment can be divided into the following situations:

[0004] 1. Installation error: During installation, improper measurement or operation may cause the two flanges to fail to align precisely, resulting in misalignment.

[0005] 2. Design or manufacturing defects: If there are design or manufacturing defects in the flange, such as inaccurate dimensions or irregular shape, misalignment can also occur.

[0006] 3. External interference: After installation, if the pipeline or equipment is subjected to external forces, such as pressure from heavy objects or other external factors, it may also cause flange misalignment.

[0007] In summary, once misalignment occurs during flange docking, adjustment is necessary to complete the docking. However, the current method requires multiple people to adjust the misalignment and is not convenient to operate, thus the flange misalignment correction effect needs to be further improved. Utility Model Content

[0008] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a flange misalignment adjustment tool.

[0009] The technical solution adopted by this utility model to solve its technical problem is:

[0010] A flange misalignment adjustment tool includes an adjustment rod with an L-shaped main body, a force-bearing steel roller, a fixing sleeve, and a screw.

[0011] The load-bearing steel roller is movably connected to the adjusting rod;

[0012] The fixing sleeve is fixed to the adjusting rod;

[0013] The screw is threadedly connected to the inside of the fixed sleeve and slides with the inside of the adjusting rod.

[0014] Furthermore, the bottom of the stressed steel roller is provided with a mounting post, the mounting post is provided with an external thread, and the adjusting rod is provided with an internal thread hole that matches the external thread.

[0015] Furthermore, the mounting column and the load-bearing steel roller are integrally formed.

[0016] Furthermore, the outer surface of the stressed steel roller is provided with annular reinforcing ribs.

[0017] Furthermore, a rubber pad is provided on the outer side of the stressed steel roller, and a storage groove adapted to the annular reinforcing rib is provided on the rubber pad.

[0018] The above solution can further improve the bending strength of the stressed steel roller by using ring-shaped reinforcing ribs. In addition, setting rubber pads on the outside of the stressed steel roller can reduce wear during its contact with the inner wall of the bolt hole.

[0019] Furthermore, a rubber layer is provided at one end of the screw, and a nut is provided at the other end of the screw.

[0020] Furthermore, the bottom of the adjusting rod is provided with a handle and the handle is provided with an anti-slip pad.

[0021] The above solution uses a handle to make it easier for workers to grip the tool during the misalignment adjustment process, and reduces the probability of slippage during gripping.

[0022] Furthermore, the surface of the adjusting rod is overlaid with a wear-resistant layer.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] Compared to existing technologies, this device requires only one person to complete the error correction and adjustment process during flange docking, thereby improving the accuracy of subsequent flange docking and operational convenience. At the same time, the manual adjustment of misaligned flanges using threaded connections ensures accurate control and better operational results for the flange misalignment adjustment process.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0031] like Figure 1 and Figure 2 As shown, a flange misalignment adjustment tool includes an adjustment rod 1 with an L-shaped main body (specifically, the surface of the adjustment rod 1 is overlaid with a wear-resistant layer to extend its service life), a force-bearing steel roller 2, a fixing sleeve 31, and a screw 32.

[0032] The load-bearing steel roller 2 is movably connected to the adjusting rod 1;

[0033] The fixing sleeve 31 is fixed on the adjusting rod 1;

[0034] The screw 32 is internally threaded to the fixed sleeve 31 and slides inside the adjusting rod 1;

[0035] One end of the screw 32 is provided with a rubber layer, and the other end of the screw 32 is provided with a nut 33.

[0036] Further refinements of the embodiments of this utility model, such as... Figure 2 As shown, the bottom of the stressed steel roller 2 is provided with a mounting post 21, the mounting post 21 is provided with an external thread 22, and the adjusting rod 1 is provided with an internal thread hole that mates with the external thread 22 (the internal thread hole is not shown in the figure). The mounting post 21 and the stressed steel roller 2 are integrally formed.

[0037] The working process of this utility model:

[0038] First, install the two flanges on the two pipes that have been maintained and need to be connected. If there is a misalignment of the flanges, then pass the load-bearing steel roller 2 through one of the bolt holes of the lower flange. First, screw the mounting post 21 into the internal thread hole to install the load-bearing steel roller 2. After the load-bearing steel roller 2 passes through the bolt hole, the nut 33 can be turned to drive the screw 32 to move horizontally. Then, one end of the screw 32 will contact the upper flange, and the position of the upper flange can be finely adjusted.

[0039] After the adjustment is completed, first move the tool away from the flange, and then install bolts into the bolt holes of the upper flange one by one to check if the error correction is successful. If it is still not right, adjust the position of the upper flange again with the tool until the center of the upper and lower flanges and the bolt holes are completely aligned. This will enable the subsequent flange docking process. It should be noted that the force-bearing steel roller 2 will come into contact with the left side wall of the threaded hole of the lower flange during the error correction process. While ensuring its strength, its diameter should be designed to be smaller to complete the misalignment correction process during the docking of flanges of different sizes.

[0040] Compared to existing technologies, this device requires only one person to complete the error correction and adjustment process during flange docking, thereby improving the accuracy of subsequent flange docking and operational convenience. At the same time, the manual adjustment of misaligned flanges using threaded connections ensures accurate control and better operational results for the flange misalignment adjustment process.

[0041] In some embodiments, the outer surface of the stressed steel roller 2 is provided with annular reinforcing ribs, which are not shown in the figure.

[0042] Further optimizations of the above-described embodiments, such as... Figure 2 As shown, a rubber pad 23 is provided on the outer side of the stressed steel roller 2, which fits tightly against it. The rubber pad 23 has a receiving groove adapted to the annular reinforcing rib. The receiving groove is not shown in the figure. In this embodiment, the annular reinforcing rib can further improve the bending strength of the stressed steel roller 2. In addition, the rubber pad 23 on the outer side of the stressed steel roller 2 can reduce the wear during the contact process with the inner wall of the bolt hole.

[0043] In other embodiments, the bottom of the adjusting rod 1 is provided with a handle 11 and an anti-slip pad is provided on the handle 11, which is not shown in the figure; in this embodiment, the handle 11 makes it convenient for the staff to grip the tool during the misalignment adjustment process and reduces the probability of slipping during the gripping process.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
