Description

Technical Field

[0001] The present invention relates to the technical field of high-temperature gas-cooled reactors, and particularly to a steam generator adjustment device. Background Art

[0002] High-temperature gas-cooled reactors are advanced nuclear energy technologies with independent intellectual property rights in China and fourth-generation technical characteristics. They have high safety characteristics, wide application fields, and very broad commercial prospects. The reactor pressure vessel cylinder and the steam generator are the main equipment of the primary loop of a high-temperature gas-cooled reactor nuclear power plant. These large and complex main equipment are the heart of the nuclear power plant, with harsh installation conditions, high precision requirements, and extremely great difficulty.

[0003] As Figure 1 shown, the steam generator 10 of the high-temperature gas-cooled reactor weighs about 420 tons and is located in the high-temperature gas-cooled reactor chamber 20. It is an important equipment of the nuclear power plant primary loop. The steam generator 10 is installed on the corbel support platform 21 of the high-temperature gas-cooled reactor chamber 20 through four support lugs 11. After the steam generator 10 is hoisted into the high-temperature gas-cooled reactor chamber 20, the position adjustment needs to be carried out first.

[0004] The high-temperature gas-cooled reactor core structure design tends to be diversified. The installation and adjustment methods used in the past can no longer meet the construction requirements of the steam generator of the high-temperature gas-cooled reactor with subsequent diversified core structure designs. When installing the steam generator in the prior art, first, the steam generator is hoisted into the nuclear island building by a large crane, and the support lugs of the steam generator are pre-supported on the corbel support platform. Then, the adjustment tooling is hoisted to the upper surface of the high-temperature gas-cooled reactor chamber and supported on the top wall of the high-temperature gas-cooled reactor chamber. Since both ends of the adjustment tooling need to be supported on the top wall of the high-temperature gas-cooled reactor chamber, its length needs to be greater than the outer diameter of the high-temperature gas-cooled reactor chamber, making the adjustment work volume in the prior art relatively large, usually weighing about 80 tons.

[0005] Then, the adjustment tooling is connected to the upper flange of the steam generator through a cable system, and then the position adjustment work is carried out through the adjustment tooling. After the steam generator adjustment is completed, the distance data between the support lugs of the steam generator and the embedded plate on the corbel support platform is measured. According to this distance data, adjustment pads with corresponding thicknesses are processed, and then the adjustment pads are inserted between the support lugs and the embedded parts of the corbel support platform to fill the gap between the two. Finally, bolts are installed and tightened for fixation. Before adjusting the next steam generator, the adjustment tooling needs to be removed and then connected to the upper flange of the next steam generator. Since the cable system needs to be disassembled and assembled with the adjustment tooling and the upper flange of the steam generator respectively, the construction time is long and the construction efficiency is low.

[0006] Therefore, how to reduce the construction time and improve the construction efficiency is a technical problem that those skilled in the art need to solve currently. Summary of the Invention

Detailed implementation manners

[0041] The core of the present invention is to provide a steam generator adjustment device to reduce construction time and improve construction efficiency.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] As Figure 2 shown, in order to facilitate the adjustment of the steam generator 10 by the steam generator adjustment device disclosed in the embodiment of the present invention, an adjustment ear rack 12 needs to be provided on the outer peripheral wall of the entire steam generator 10. The structure of the adjustment ear rack 12 is similar to that of the support ear rack 11. Usually, there are at least two adjustment ear racks 12. Since two adjustment ear racks 12 can assist in completing the adjustment of the position parameters of the entire steam generator 10, in this embodiment, there are two adjustment ear racks 12, and they are symmetrically arranged on the outer peripheral surface of the steam generator 10 along the axis center of the steam generator 10. The height of the lower surface of the adjustment ear rack 12 can be the same as the height of the lower surface of the support ear rack 11 of the steam generator 10, or it can of course be designed to be higher than the height of the lower surface of the support ear rack 11.

[0044] The present invention can adjust the two adjustment ear racks 12 on the steam generator 10 to make the position parameters such as the elevation, levelness, and coaxiality of the steam generator 10 meet the design requirements, and then fix the four support ear racks 11 of the steam generator 10 on the bracket support platform 21 of the high-temperature gas-cooled reactor compartment 20 to complete the adjustment and installation of the steam generator 10. Next, the specific structure of the steam generator adjustment device disclosed in the embodiment of the present invention will be introduced.

[0045] As Figure 3 and Figure 6As shown in the figure, an embodiment of the present invention discloses a steam generator adjustment device, which includes an adjustment mechanism for cooperating with the adjustment ear brackets 12 of the steam generator 10 to adjust the position of the steam generator 10. The adjustment mechanism has two corresponding to the two adjustment ear brackets 12. That is, if the steam generator 10 has two adjustment ear brackets 12, the adjustment mechanism also needs to be two and cooperate with the two adjustment ear brackets 12 respectively. Correspondingly, if the steam generator 10 has three adjustment ear brackets 12, the adjustment mechanism also needs to be three and cooperate with the three adjustment ear brackets 12 respectively.

[0046] The adjustment mechanism includes an adjustment tooling 30 and two three-dimensional adjustment jacks 40. The adjustment tooling 30 includes a transverse support beam 31 and a jacking frame. Among them, the transverse support beam 31 has an ear bracket support part for supporting the adjustment ear bracket 12. The jacking frame is connected to the transverse support beam 31. The two three-dimensional adjustment jacks 40 are respectively located on both sides of the ear bracket support part, and the Z-axis cylinders of the two three-dimensional adjustment jacks 40 are both used to jack up the jacking frame. The adjustment tooling 30 can be assembled with steel sections and directly hoisted into the high-temperature gas-cooled reactor chamber 20 for use. Therefore, its size is smaller than the diameter of the high-temperature gas-cooled reactor chamber 20, which can save material costs, reduce the occupied site and resources such as cranes. At the same time, the tooling is small and simple to manufacture, and can be mass-produced.

[0047] The three-dimensional adjustment jack 40 includes an X-axis cylinder, a Y-axis cylinder and a Z-axis cylinder. The X-axis cylinder and the Y-axis cylinder are used to control the Z-axis cylinder to move in the X direction and the Y direction respectively. The Z-axis cylinder is used to control the lifting of the jacking frame, that is, to control the jacking frame to move in the Z direction. Therefore, the jacking frame can be adjusted in the X, Y and Z directions under the action of the X-axis cylinder, Y-axis cylinder and Z-axis cylinder of the three-dimensional adjustment jack 40, that is, the adjustment in space can be realized. The three-dimensional adjustment jack 40 is a commonly used three-dimensional adjustment device in the prior art, and its specific structure will not be described in detail herein.

[0048] Since the jacking frame is connected to the transverse support beam 31, when the three-dimensional adjustment jack 40 adjusts the jacking frame, it also adjusts the spatial position of the transverse support beam 31, and then adjusts the spatial position of the steam generator 10.

[0049] Each adjustment ear bracket 12 corresponds to an adjustment mechanism. Each adjustment mechanism has two three-dimensional adjustment jacks 40, and the two three-dimensional adjustment jacks 40 are respectively located on both sides of the ear bracket support part, that is, on both sides of the adjustment ear bracket 12. Therefore, the spatial position of the adjustment ear bracket 12 can be adjusted by the two three-dimensional adjustment jacks 40. Combining with the adjustment mechanism corresponding to another adjustment ear bracket 12, various spatial dimension adjustments of the steam generator 10 can be realized, so that the positional parameters such as the elevation, levelness and coaxiality of the steam generator 10 meet the requirements of the design documents.

[0050] Since the steam generator 10 has two adjustment brackets 12, the steam generator adjustment device disclosed in the embodiment of the present invention needs to be configured with four three-dimensional adjustment jacks 40. In order to coordinate the work of the four three-dimensional adjustment jacks 40, it is usually necessary to configure a main control cabinet (with a hydraulic pump station), input the position data to be adjusted in the main control cabinet, and the main control cabinet synchronously controls the 4 three-dimensional adjustment jacks 40 to move the steam generator 10 in the X, Y, and Z directions, so that the elevation, levelness, and coaxiality of the steam generator 10 meet the requirements of the design document.

[0051] The steam generator adjustment device provided by the present invention adjusts the positional accuracy of the steam generator 10 by using the adjustment brackets 12 provided on the outer peripheral wall of the steam generator 10. Before installing the steam generator 10, it is necessary to hoist the steam generator adjustment device onto the corbel support platform 21 of the high-temperature gas-cooled reactor compartment 20, and then hoist the steam generator 10 into the high-temperature gas-cooled reactor compartment 20. After that, support the adjustment brackets 12 on the bracket support part of the transverse support beam 31, and then adjust the spatial position parameters of the steam generator 10 by adjusting the three-dimensional adjustment jacks 40. After adjusting the steam generator 10 to the appropriate position, measure the distance data between the support brackets 11 of the steam generator 10 and the embedded plates on the corbel support platform 21. The positions of the 4 support brackets 11 corresponding to the corbel support platform 21 can generally be designed to be higher than other positions of the corbel support platform 21, and are provided with embedded plates. The embedded plates are provided with bolt holes. A shim plate needs to be provided between each support bracket 11 of the steam generator 10 and the embedded plate of the corbel support platform 21, and the shim plate is machined with clearance holes corresponding to the bolt hole positions of the embedded parts.

[0052] After measuring the distance data between the support brackets 11 of the steam generator 10 and the embedded plates on the corbel support platform 21, process the shim plates with corresponding thicknesses according to the distance data, and then insert the shim plates into the gaps between the support brackets 11 of the steam generator 10 and the embedded parts of the corbel support platform 21 to fill the gaps between the two, and finally install and tighten the bolts. After the steam generator 10 is fixed, by controlling the Z-axis cylinder of the three-dimensional adjustment jack 40 to descend, the separation of the adjustment bracket 12 from the transverse support beam 31 can be completed. Compared with the prior art, there is no need to disassemble and assemble by bolts, which is convenient for replacing and adjusting the next steam generator, reduces the time occupied by the main line project, and improves the construction efficiency.

[0053] Such as Figure 4 and Figure 5As shown, in a specific embodiment of the present invention, the jacking frame includes an upper support assembly and a lower support assembly. Among them, the upper support assembly includes a first diagonal support 33 and a second diagonal support 34. The first end of the first diagonal support 33 is connected to the first end of the second diagonal support 34, and the first diagonal support 33 and the second diagonal support 34 are not on the same straight line, so that the angle between the first diagonal support 33 and the second diagonal support 34 is greater than 0° and less than 180°. Figure 4 The scheme shown is that the first diagonal support 33 and the second diagonal support 34 are at a right angle. It should be noted that the first diagonal support 33 and the second diagonal support 34 can also be at an acute angle or an obtuse angle.

[0054] The height of the second end of the first diagonal support 33 is lower than the height of the first end of the first diagonal support 33, and the height of the second end of the second diagonal support 34 is lower than the height of the first end of the second diagonal support 34, that is, the height of the intersecting end of the first diagonal support 33 and the second diagonal support 34 is higher than the height of the other end.

[0055] One end of the lower support assembly is connected to the second end of the first diagonal support 33, and the other end is connected to the second end of the second diagonal support 34. The height of the lower support assembly is higher than the height of the transverse support beam 31. The lower support assembly cooperates with the Z-axis cylinder of the three-dimensional adjustment jack 40. The first diagonal support 33, the second diagonal support 34 and the lower support assembly as a whole form a triangular structure, and the three-dimensional adjustment jack 40 is jacked on both sides of the bottom edge of the triangular structure. This embodiment utilizes the stability effect of the triangular structure, which is beneficial to enhancing the overall stability of the adjustment tooling 30.

[0056] Specifically, the second end of the first diagonal support 33 and the second end of the second diagonal support 34 are in the same plane. The plane where the second end of the first diagonal support 33 and the second end of the second diagonal support 34 are located forms an acute angle with the extension directions of both the first diagonal support 33 and the second diagonal support 34, so that the end faces of the second end of the first diagonal support 33 and the second end of the second diagonal support 34 have a larger surface area, so as to increase the contact area with the lower support assembly and improve the connection stability.

[0057] For ease of understanding, the plane where the second end of the first diagonal support 33 and the second end of the second diagonal support 34 are located is defined as the first plane, and the plane where the ear support part is located (that is, the upper surface of the ear support part) is defined as the second plane. Then the first plane and the second plane are parallel, so that the plane supported by the three-dimensional adjustment jack 40 is parallel to the plane supporting the adjustment ear 12, which is convenient for adjusting the spatial form of the steam generator 10.

[0058] Such as Figure 4 and Figure 5As shown in the figure, in order to improve the strength of the adjustment tooling 30, there are two upper support components arranged in parallel. The two upper support components can be arranged in parallel with a certain gap therebetween. The gap should not be too large to reduce the spatial dimension of the adjustment tooling 30. Specifically, the gap between the two upper support components can be smaller than the widths of the first diagonal support 33 and the second diagonal support 34.

[0059] The lower support component includes a transverse support 35 and a longitudinal support 32. There are two transverse supports 35 respectively connected to the upper support components one by one. One end of the transverse support 35 is connected to the second end of the first diagonal support 33, and the other end is connected to the second end of the second diagonal support 34. The transverse support 35 does not completely cover the end faces of the second ends of the first diagonal support 33 and the second diagonal support 34, so as to reserve an installation space for the longitudinal support 32.

[0060] There are two longitudinal supports 32. One of the longitudinal supports 32 is fixed to one end of the two transverse supports 35 and is fixed to the second ends of the two first diagonal supports 33, that is, the part of the end face of the second end of the first diagonal support 33 not covered by the transverse support 35 is covered by the longitudinal support 32. This longitudinal support 32 extends from the second end of one of the first diagonal supports 33 to the second end of the other first diagonal support 33.

[0061] Similarly, the other longitudinal support 32 is fixed to the other end of the two transverse supports 35 and is fixed to the second ends of the two second diagonal supports 34, that is, the part of the end face of the second end of the second diagonal support 34 not covered by the transverse support 35 is covered by the longitudinal support 32. This longitudinal support 32 extends from the second end of one of the second diagonal supports 34 to the second end of the other second diagonal support 34.

[0062] The two upper support components arranged in parallel at intervals are connected into a stable triangular structure under the action of the two transverse supports 35 and the two longitudinal supports 32. Moreover, the width of the adjustment tooling 30 is increased, the support for the adjustment ear bracket 12 is more stable, and a larger support position area can also be provided for the three-dimensional adjustment jack 40.

[0063] Specifically, in order to improve the installation stability of the three-dimensional adjustment jack 40, a cylindrical sleeve 37 is provided on the lower surface of the longitudinal support 32. The cylindrical sleeve 37 is matched with the Z-axis cylinder of the three-dimensional adjustment jack 40. The cylindrical sleeve 37 can be arranged at the middle position of the longitudinal support 32 to maintain stability during the jacking action and prevent the adjustment tooling 30 from twisting when being jacked up.

[0064] The piston rod of the Z-axis oil cylinder of the three-dimensional adjustment jack 40 can be inserted into the cylindrical sleeve 37, preventing relative sliding between the Z-axis oil cylinder and the longitudinal support 32 when the three-dimensional adjustment jack 40 is adjusted in the X or Y direction, and affecting the adjustment accuracy of the position degree. Under the limiting effect of the cylindrical sleeve 37, the piston rod of the Z-axis oil cylinder is restricted within the cylindrical sleeve 37, avoiding relative sliding between the Z-axis oil cylinder and the longitudinal support 32 when the three-dimensional adjustment jack 40 is adjusted.

[0065] As Figure 4 and Figure 5 shown, both the first diagonal support 33 and the second diagonal support 34 are connected to the transverse support beam 31 through the vertical support 36. Since there are two upper support assemblies, there are two first diagonal supports 33 and two second diagonal supports 34 accordingly, and there are four vertical supports 36, two of which are respectively connected to the two first diagonal supports 33, and the other two are respectively connected to the two second diagonal supports 34. The four vertical supports 36 are parallel to each other.

[0066] Two transverse support beams 31 can be provided. For the convenience of understanding, the vertical support 36 connected to one of the upper support assemblies is defined as the first vertical support, and the vertical support 36 connected to the other upper support assembly is defined as the second vertical support. One of the transverse support beams 31 is connected to the first vertical support, and the other transverse support beam 31 is connected to the second vertical support. The upper surfaces of the two transverse support beams 31 are located in the same plane, so that the two transverse support beams 31 can provide a larger support area for the adjustment earpiece 12 and improve the stability of the support.

[0067] For the convenience of understanding, the transverse support 35 connected to one of the upper support assemblies is defined as the first transverse support, and the transverse support 35 connected to the other upper support assembly is defined as the second transverse support. Then in this embodiment, the first transverse support intersects with the first vertical support (preferably perpendicularly), and is an integral structure. Correspondingly, the second transverse support intersects with the second vertical support (preferably perpendicularly), and is an integral structure.

[0068] In this embodiment, the first transverse support is arranged to intersect with the two first vertical supports and is an integral structure. At the same time, the second transverse support is arranged to intersect with the two second vertical supports and is an integral structure. Moreover, one of the longitudinal supports 32 is connected to the first ends of the first transverse support and the second transverse support (for example Figure 4 shown on the left side of the first transverse support and the second transverse support), and the other longitudinal support 32 is connected to the second ends of the first transverse support and the second transverse support (for example Figure 4on the right side of the shown first lateral support and second lateral support), such that the longitudinal support 32, the first lateral support, the first vertical support, the second lateral support, and the second vertical support form a stable support frame structure, and connect the upper side of the support frame structure to the first diagonal support 33 and the second diagonal support 34, and connect the lower side to the lateral support beam 31, so that the entire adjustment tooling 30 is connected into a stable frame to be able to bear the weight of the steam generator 10.

[0069] It should be noted that the adjacency between the various components described in the text means that the connection manner between two components can be fixed by fasteners, fixed by welding, or designed as an integral structure, etc.

[0070] It should be noted that the various embodiments in this specification are all described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts between the various embodiments, reference can be made to each other.
