Description

Technical Field

[0001] The invention relates to the technical field of nuclear power installation, and in particular to a device for controlling concentricity during a penetration welding process. Background Art

[0002] The internal and external structures of the nuclear reactor building are double-layer containment shells. The penetration pieces are key components that ensure that the inside and outside can be tightly connected when the pipeline passes through the double-layer containment shell, and can meet the system pipeline design requirements under various working conditions while ensuring the airtightness and integrity of the containment shell.

[0003] The installation of pipeline penetrations includes two parts: the penetration body and the sealing ring. At present, the dome penetration is usually first fixed by the civil construction unit to the civil sleeve and the double-layer shell of the nuclear island, and then the penetration body is introduced into the civil sleeve, and then the body and the civil sleeve are welded, or after the dome penetration and the civil sleeve are welded, the upstream and downstream pipelines are welded to connect the inside and outside of the nuclear island. However, the above scheme will cause the concentricity offset of the penetration and the civil sleeve during the welding process, which will result in the need for multiple adjustments during the welding process, reducing the welding efficiency and having a certain impact on the welding quality.

[0031] like Figure 1 to Figure 2As shown, the present invention provides a device for controlling the concentricity of a penetration welding process, comprising a mounting mechanism, a connecting mechanism and a positioning mechanism; the mounting mechanism is provided with a through hole, and the mounting mechanism is sleeved on the outside of the penetration 100 through the through hole, and is located between the penetration 100 and the civil sleeve 101; there are multiple connecting mechanisms, and they are evenly spaced along the circumferential direction of the upper surface of the mounting mechanism, the positioning mechanism corresponds to the connecting mechanism one by one, and the ends of the positioning mechanism pass through the connecting mechanism and alternately abut against the side walls of the penetration 100 or the civil sleeve 101.

[0032] In this embodiment, the device includes an installation mechanism, a connecting mechanism and a positioning mechanism. When in use, the installation mechanism is sleeved on the outside of the penetration piece 100 and is located at the portion overlapping with the civil sleeve 101. The connection mechanism is evenly spaced circumferentially on the upper surface of the installation mechanism, and the positioning mechanism passes through the connecting mechanism and alternately abuts against the side walls of the penetration piece 100 or the civil sleeve 101. The two cooperate to adjust the distance between the penetration piece 100 and the installation mechanism and the distance between the civil sleeve 101 and the installation mechanism to ensure concentricity. This can reduce the concentricity deviation during construction, thereby reducing the deformation problem caused by lack of control during welding, and can also effectively improve work efficiency.

[0033] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the connection mechanism includes a connection seat 200, which is fixed on the upper surface of the mounting mechanism and is evenly spaced along the circumference of the upper surface of the mounting mechanism.

[0034] In this embodiment, the connecting mechanism includes a connecting seat 200, wherein, preferably, the connecting seat 200 is fixed on the upper surface of the mounting mechanism and fixed by welding, and is evenly spaced along the circumference of the surface of the mounting mechanism, so that after the positioning mechanism passes through, the distance between the penetration piece 100 and the mounting mechanism and the distance between the civil sleeve 101 and the mounting mechanism can be accurately controlled.

[0035] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, a connecting hole is provided on the connecting seat 200 , and the end of the positioning mechanism passes through the connecting hole and abuts against the side wall of the penetration piece 100 or the civil engineering sleeve 101 .

[0036] In this embodiment, a connecting hole is provided on the connecting seat 200, and the end of the positioning mechanism is used to pass through the connecting hole and abut against the side wall of the penetration piece 100 or the civil sleeve 101, so that the protruding end length of the positioning mechanism after passing through the connecting seat 200 can be adjusted to be consistent to ensure the concentricity of the penetration piece 100 and the civil sleeve 101. It can be adjusted into place at one time, which can effectively reduce labor intensity and improve work efficiency.

[0037] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, there are at least four connecting seats 200, and the number is an even number, which are evenly distributed along the circumferential direction of the upper surface of the mounting mechanism.

[0038] In this embodiment, at least four connecting seats 200 are provided, and the number is set to an even number. Since the ends of the positioning mechanism pass through the connecting seats 200 and alternately abut against the side walls of the penetration piece 100 or the civil sleeve 101, it is necessary to ensure that the positioning mechanism on the connecting seat 200 arranged diagonally passes through and then abuts against the side wall of the same component, that is, the end of the positioning mechanism on the connecting seat 200 arranged diagonally along the installation mechanism is straight after passing through the connecting seat 200.

[0039] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the positioning mechanism includes a positioning member 300 , and the end of the positioning member 300 passes through the connecting hole and abuts against the side wall of the penetration member 100 or the civil engineering sleeve 101 .

[0040] In this embodiment, the positioning mechanism includes a positioning member 300, and the end of the positioning member 300 directly passes through the connecting hole and abuts against the side wall of the penetration member 100 or the civil sleeve 101. It is only necessary to keep the end length of the positioning member 300 abutting against the side wall of the penetration member 100 or the civil sleeve 101 after passing through the connecting seat 200 consistent, so as to achieve a concentric effect, clear distance, simple operation, and can be adjusted into place at one time, thereby improving the operation accuracy.

[0041] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the positioning member 300 is a positioning bolt.

[0042] In this embodiment, preferably, the positioning member 300 is set as a positioning bolt, and correspondingly, the connecting seat 200 is set as a nut that can be used in conjunction with the positioning bolt. The nut is welded and fixed on the surface of the mounting mechanism, and the length of the end of the positioning bolt protruding from the nut can be accurately controlled by cooperating with the thread at the end of the positioning bolt and the thread on the inside of the nut, which can effectively improve the operation accuracy and ensure the quality of the operation.

[0043] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the positioning bolt includes a bolt body and a bolt head, one end of the bolt body is connected to one side of the bolt head, and the other end of the bolt body passes through the connecting seat 200 and abuts against the side wall of the penetration piece 100 or the civil engineering sleeve 101.

[0044] In this embodiment, the positioning bolt includes a bolt body and a bolt head, wherein one end of the bolt body is welded and fixed to the bolt head, and the other end is used to pass through the connecting seat 200 and then abut against the side wall of the penetration piece 100 or the civil sleeve 101. Therefore, it is only necessary to measure the length of the end of the bolt body that abuts against the side wall of the penetration piece 100 or the civil sleeve 101 after passing through the connecting seat 200 and keep it consistent to achieve a concentric effect. The operation is simple, can reduce labor intensity, and improve subsequent welding efficiency.

[0045] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the installation mechanism includes a mounting ring 400 , a through hole is formed inside the mounting ring 400 , and the mounting ring 400 is sleeved between the penetration piece 100 and the civil engineering sleeve 101 .

[0046] In this embodiment, the mounting mechanism includes a mounting ring 400, and a through hole is formed on the inner side of the mounting ring 400. The mounting ring 400 is sleeved on the outer side of the penetration piece 100 by using the through hole, and is located at the overlapping portion of the penetration piece 100 and the civil engineering sleeve 101, so that the connecting seat 200 arranged thereon can cooperate with the positioning piece 300 to adjust the concentricity of the penetration piece 100 and the civil engineering sleeve 101.

[0047] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the connection seats 200 are disposed on the upper surface of the mounting ring 400 and are arranged at intervals along the circumferential direction of the edge of the mounting ring 400 .

[0048] In this embodiment, the connecting seat 200 is arranged on the upper surface of the mounting ring 400, and the connecting seat 200 is arranged at equal intervals along the circumferential edge of the mounting ring 400, that is, the connecting seat 200 is symmetrically arranged, and the two symmetrically arranged connecting seats 200 are symmetrical along the diameter of the mounting ring 400, and the ends of the positioning members 300 passing through the two symmetrical connecting seats 200 are oriented in the same direction, ensuring that the ends of the positioning members 300 pass through the connecting mechanism and alternately abut against the side walls of the through-piece 100 or the civil sleeve 101. When adjustment is needed, only the two adjacent positioning members 300 need to be adjusted, which makes the operation simpler.

[0049] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, there are eight connecting seats 200 , which are evenly distributed along the edge of the upper surface of the mounting ring 400 .

[0050] In this embodiment, preferably, 8 connecting seats 200 are provided, and the 8 connecting seats 200 are equally spaced axially along the upper surface of the mounting ring 400. It is only necessary to keep the end length of the positioning member 300 that abuts against the side wall of the through-piece 100 or the civil sleeve 101 after passing through the connecting seat 200 consistent, so as to achieve a concentric effect.

[0051] Among them, optionally, the number of the connecting sockets 200 can also be six, ten or other even numbers greater than four, and the purpose thereof does not deviate from the design concept of the present invention and should fall within the protection scope of the present invention.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
