Description

Technical Field

[0001] The utility model relates to the technical field of transformer component preparation, in particular to a pressure test tooling for a bushing flange of a transformer riser. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] During the production and use of the bushing flange of the transformer riser, flange pressure testing is an important link to ensure its quality. Its main purpose is to verify whether the flange connection in the pipeline system can withstand the predetermined pressure and ensure that there is no leakage during actual operation. However, there are some deficiencies in the existing flange pressure test tooling. The existing tooling has a complex structure and inconvenient operation, resulting in low pressure test efficiency. In addition, the stability and sealing performance of some tooling are poor, making it difficult to accurately detect the performance of the flange, thus affecting the product quality.

[0004] Therefore, those skilled in the art are committed to developing a pressure test tooling for a bushing flange of a transformer riser, which can quickly clamp and seal the bushing flange of the transformer riser, facilitating subsequent pressure testing. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a pressure test tooling for a bushing flange of a transformer riser, which can quickly clamp and seal the bushing flange of the transformer riser, facilitating subsequent pressure testing.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] A pressure test tooling for a bushing flange of a transformer riser, comprising

[0008] A first tooling body;

[0009] A second tooling body, the second tooling body is connected to the first tooling body through a connecting plate, and both the first tooling body and the second tooling body have abutting parts for abutting against the flange;

[0010] An adjusting component, the adjusting component is installed on the first tooling body and the second tooling body;

[0011] A plug plate component, the plug plate component is installed on the moving end of the adjusting component, and the plug plate component is arranged opposite to the abutting part.

[0012] The beneficial effects of adopting the above solution are as follows: The first tooling body and the second tooling body are connected by a connecting plate. The abutting parts on the first tooling body and the second tooling body abut against one side of the flange. By means of the adjusting assembly, the plugging plate assembly abuts against the other side of the flange, thereby plugging the end of the flange, which is beneficial for subsequent pressure testing and improves the test efficiency of the flange.

[0013] On the basis of the above technical solution, the present utility model can also be improved as follows.

[0014] Further, both the first tooling body and the second tooling body include a first tooling piece, a second tooling piece, and a third tooling piece that are connected in sequence. The two ends of the second tooling piece are perpendicular to the first tooling piece and the third tooling piece respectively. The side of the first tooling piece opposite to the plugging plate assembly is the abutting part.

[0015] The beneficial effects of adopting the above further solution are as follows: The first tooling piece, the second tooling piece, and the third tooling piece form a tooling that is roughly U-shaped, which is beneficial for clamping the flange.

[0016] Further, the adjusting assembly includes an adjusting plate. The adjusting plate is installed on the first tooling body and the second tooling body. The adjusting plate has a threaded hole, and a threaded rod that mates with the threaded hole is inserted into the threaded hole. One end of the threaded rod is connected to the plugging plate assembly, and the other end of the threaded rod is connected to a rotating rod.

[0017] The beneficial effects of adopting the above further solution are as follows: Rotating the threaded rod causes the plugging plate assembly to move, so that the end face of the plugging plate assembly abuts against and plugs the end face of the flange.

[0018] Further, the plugging plate assembly includes a plugging plate disc. The plugging plate disc has a middle groove and an arc-shaped groove on the side opposite to the abutting part.

[0019] The beneficial effects of adopting the above further solution are as follows: The middle groove and the arc-shaped groove on the plugging plate disc are beneficial for cooperating with the end face of the flange to plug one side of the flange.

[0020] Further, the distance between the end of the first tooling body and the end of the second tooling body near the connecting plate is greater than the distance between the end of the first tooling body and the end of the second tooling body far from the connecting plate.

[0021] The beneficial effects of adopting the above further solution are as follows: The first tooling body, the second tooling body, and the connecting plate are roughly V-shaped, which is beneficial for adapting to flanges of different diameters.

[0022] Further, adjustment slots are provided at corresponding positions of the two third tooling parts. Both ends of the adjustment plate are connected with sliding plates, the sliding plates are arranged in the adjustment slots, and a plurality of fastening bolts for fixing the sliding plates are further arranged on the third tooling parts.

[0023] The beneficial effect of adopting the above further scheme is that the sliding plates move in the adjustment slots and drive the plug plate assembly to move so as to adapt to flanges with different diameters.

[0024] Further, connection holes are provided at corresponding positions of the ends of the first tooling part and the third tooling part, a connection screw rod is arranged in the connection holes, and a rotating handle is installed at the end of the connection screw rod.

[0025] The beneficial effect of adopting the above further scheme is that by rotating the handle, the connection screw rod connects the ends of the first tooling part and the third tooling part, improving the overall strength of the pressure test tooling and avoiding the tooling from breaking during the pressure test.

[0035] Embodiment 1

[0036] As Figure 1 、 Figure 2 and Figure 3 shown, a pressure test tooling for the flange of the transformer riser bushing includes

[0037] a first tooling body 1;

[0038] a second tooling body 2, the second tooling body 2 is connected to the first tooling body 1 through a connecting plate 3, and both the first tooling body 1 and the second tooling body 2 have abutting parts 4 for abutting against the flange;

[0039] an adjusting assembly 5, the adjusting assembly 5 is installed on the first tooling body 1 and the second tooling body 2;

[0040] a plug plate assembly 6, the plug plate assembly 6 is installed on the moving end of the adjusting assembly 5, and the plug plate assembly 6 is arranged opposite to the abutting part 4.

[0041] In the present utility model, the first tooling body 1 and the second tooling body 2 are connected through the connecting plate 3. The abutting parts 4 on the first tooling body 1 and the second tooling body 2 abut against one side of the flange. By means of the adjusting assembly 5, the plug plate assembly 6 abuts against the other side of the flange, thereby blocking the end of the flange, which is beneficial to subsequent pressure test detection and improves the test efficiency of the flange.

[0042] As Figure 1 、 Figure 2 shown, in some embodiments, both the first tooling body 1 and the second tooling body 2 are generally U-shaped. Specifically, both the first tooling body 1 and the second tooling body 2 include a first tooling part 7, a second tooling part 8, and a third tooling part 9 that are sequentially connected. The two ends of the second tooling part 8 are respectively perpendicular to the first tooling part 7 and the third tooling part 9. The two ends of the connecting plate 3 are specifically connected to the second tooling part 8. The side of the first tooling part 7 opposite to the plugging plate assembly 6 is an abutting part 4, and the abutting part 4 is mainly used to abut against one side of the flange, which is beneficial for plugging the flange subsequently.

[0043] As Figure 2 shown, in another embodiment, the adjusting assembly 5 includes an adjusting plate 10. The adjusting plate 10 is installed on the first tooling body 1 and the second tooling body 2.

[0048] In the embodiment, connection holes 19 are provided at corresponding positions at the ends of the first tooling part 7 and the third tooling part 9. The connection holes 19 are threaded holes, and connection screws 20 are inserted into the connection holes 19. A rotating handle 21 is installed at the end of the connection screw 20. The rotating handle 21 drives the connection screw 20 to rotate to connect the ends of the first tooling part 7 and the third tooling part 9, improving the overall strength of the pressure test tooling.
