[0003] Among them, two busbar expansion joint rubber sleeves are installed in each phase of the main busbar horizontal section of the nuclear power generator enclosed busbar, and the material of the expansion joint rubber sleeve is ethylene propylene rubber; when the expansion joint rubber sleeve of the enclosed busbar of the nuclear power generator ages or is damaged and there is a leakage point, the expansion joint rubber sleeve needs to be replaced.

[0065] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0066] The device provided by the embodiment of the present invention for bonding the rubber sleeve of the expansion joint of the nuclear power generator busbar, wherein, after the rubber sleeve 7 of the expansion joint is cut off, it is sleeved on the outer shell of the closed busbar, and the two cut ends of the rubber sleeve 7 of the expansion joint are aligned, as Figure 3 and Figure 4 shown. The device includes: a first connecting member, a second connecting member and a fixture assembly;

[0067] The first connecting member is used for bonding to the inner wall at the two aligned cut ends of the rubber sleeve 7 of the expansion joint and covering the seam formed by the two aligned cut ends of the rubber sleeve 7 of the expansion joint;

[0068] The second connecting member is used for bonding to the outer wall at the two aligned cut ends of the rubber sleeve 7 of the expansion joint and covering the seam formed by the two aligned cut ends of the rubber sleeve 7 of the expansion joint;

[0069] The fixture assembly is used for clamping the first connecting member and the second connecting member, so that the first connecting member is pressed against the inner wall at the two aligned cut ends of the rubber sleeve 7 of the expansion joint, and the second connecting member is pressed against the outer wall at the two aligned cut ends of the rubber sleeve 7 of the expansion joint.

[0070] It should be noted that, as Figure 10 shown, the above-mentioned rubber sleeve 7 of the expansion joint is the spare part of the rubber sleeve of the expansion joint, that is, the new rubber sleeve 7 of the expansion joint. After the rubber sleeve 7 of the expansion joint is cut along the direction parallel to the axial direction (such as the cut position 7-4 in Figure 10 ), it can be sleeved on the outer shell of the closed busbar (not shown in the figure). Moreover, when the rubber sleeve 7 of the expansion joint is sleeved on the outer shell of the closed busbar, its two cut ends are aligned for bonding. Of course, after the rubber sleeve 7 of the expansion joint is cut and unfolded, it is rectangular; Figure 5 What is shown in

[0071] is a part of the rubber sleeve 7 of the expansion joint, and this part is the part of the rubber sleeve 7 of the expansion joint on both sides of the seam;

[0072] The first connecting piece and the second connecting piece are used to respectively cover and adhere to the inner wall and the outer wall of the seam formed by the two aligned incisions of the expansion joint rubber sleeve 7, that is, to cover and adhere to the inner and outer walls of the seam of the expansion joint rubber sleeve 7 sleeved on the outer shell of the enclosed busbar, so that the two aligned incisions of the expansion joint rubber sleeve 7 are covered and adhered. Then, the first connecting piece and the second connecting piece are clamped by the fixture assembly, so that the first connecting piece is pressed after being adhered to the inner wall at the two aligned incisions of the expansion joint rubber sleeve 7, and the second connecting piece is crimped after being adhered to the outer wall at the two aligned incisions of the expansion joint rubber sleeve 7. Thus, the covering and adhesion of the inner and outer walls of the seam of the expansion joint rubber sleeve 7 by the first connecting piece and the second connecting piece are more firm and reliable, ensuring that the connection of the two aligned incisions of the expansion joint rubber sleeve 7 meets the use requirements. In this way, it helps to realize the replacement of the expansion joint rubber sleeve 7 on the enclosed busbar. That is to say, after the expansion joint rubber sleeve 7 (expansion joint rubber sleeve spare part) is cut off, it is convenient to be sleeved on the outer shell of the enclosed busbar, and then the inner and outer walls of the seam of the expansion joint rubber sleeve 7 are firmly covered and adhered by this device. Finally, the expansion joint rubber sleeve 7 is installed in place.

[0073] Thus, it can be seen that the expansion joint rubber sleeve 7 can be sleeved on the outer shell of the enclosed busbar by cutting it off. Then, the first connecting piece is adhered to the inner wall of the two aligned incisions (seam) of the expansion joint rubber sleeve 7, and the second connecting piece is adhered to the outer wall of the two aligned incisions (seam) of the expansion joint rubber sleeve 7, that is, to cover and adhere to the inner wall and the outer wall of the seam of the expansion joint rubber sleeve 7, so that the two aligned incisions of the expansion joint rubber sleeve 7 are adhered together. Then, the first connecting piece and the second connecting piece are clamped by the fixture assembly, and the covering and adhesion of the inner and outer walls of the seam of the expansion joint rubber sleeve 7 are crimped, so that the first connecting piece is fully adhered to the inner wall of the two aligned incisions of the expansion joint rubber sleeve 7, and the second connecting piece is fully adhered to the outer wall of the two aligned incisions of the expansion joint rubber sleeve 7. Thus, the covering and adhesion of the inner and outer walls of the seam of the expansion joint rubber sleeve 7 are firm, reliable, durable, and can realize the effective and reliable connection of the two aligned incisions of the expansion joint rubber sleeve 7. Subsequently, it also helps to realize the replacement of the expansion joint rubber sleeve 7 on the enclosed busbar, thus facilitating the solution of the problem that the expansion joint rubber sleeve of the generator enclosed busbar cannot be replaced. Of course, this also saves a large amount of workload, saves the overhaul period, and improves the work efficiency.

[0074] In this solution, as Figure 3 shown, the fixture assembly includes: a first clamp body 1, a second clamp body 2, and a locking assembly;

[0075] The first clamp body 1 is used to be arranged inside the two aligned incisions of the expansion joint rubber sleeve 7 along the first direction and is in contact and cooperation with the first connecting piece;

[0076] The second clamping body 2 is used to be arranged on the outer sides of the two aligned cutouts of the expansion joint rubber sleeve 7 along the first direction and is in contact and cooperation with the second connecting piece; wherein, the first direction is parallel to the axial direction of the expansion joint rubber sleeve 7.

[0077] The locking assembly is used to lock the first clamping body 1 and the second clamping body 2 so that the first clamping body 1 and the second clamping body 2 clamp the first connecting piece and the second connecting piece.

[0078] It should be noted that the expansion joint rubber sleeve 7 has elasticity in the radial direction and has a certain movement space. In this way, it is convenient to lift the two aligned cutouts (adhered with the first connecting piece) of the expansion joint rubber sleeve 7, and then place the first clamping body 1 on the inner sides of the two aligned cutouts of the expansion joint rubber sleeve 7 along the first direction. The first clamping body 1 is also correspondingly located on the outer shell of the enclosed busbar. Of course, the first connecting piece can also be first arranged on (adherable to) the first clamping body 1, and after the first clamping body 1 is placed on the inner sides of the two aligned cutouts of the expansion joint rubber sleeve 7 along the first direction, the first connecting piece is adhered to the inner walls of the two aligned cutouts of the expansion joint rubber sleeve 7. Among them, the adhesion of the first connecting piece to the inner walls of the two aligned cutouts of the expansion joint rubber sleeve 7 and the contact and cooperation of the first connecting piece with the first clamping body 1 do not require a specific sequence, and the same is true for the second connecting piece. In addition, as Figure 3 shown, the first clamping body 1 is equivalent to an inner clamping body, and this inner clamping body can adopt an inner clamping plate and can be used to be in contact and cooperation with the first connecting piece (inner connecting piece) adhered to the inner walls of the two aligned cutouts of the expansion joint rubber sleeve 7. The second clamping body 2 is equivalent to an outer clamping body, and this outer clamping body can adopt an outer clamping plate and can be used to be in contact and cooperation with the second connecting piece (outer connecting piece) adhered to the outer walls of the two aligned cutouts of the expansion joint rubber sleeve 7. Then, the first clamping body 1 and the second clamping body 2 are locked or fastened by the locking assembly, that is, the locking assembly makes the first clamping body 1 and the second clamping body 2 have a tendency to buckle, so that the first clamping body 1 and the second clamping body 2 clamp the first connecting piece and the second connecting piece, and further makes the first clamping body 1 press the first connecting piece and the second clamping body 2 press the second connecting piece, thereby realizing the crimping (pressing) of the covering adhesion of the inner wall and the outer wall of the seam of the expansion joint rubber sleeve 7. Of course, the locking assembly is also equivalent to a clamping body locking assembly or a clamping body fastening assembly.

[0079] That is to say, for the expansion joint rubber sleeve 7 sleeved on the outer shell of the enclosed busbar, the inner walls and the outer walls of the two aligned cutouts are adhesively bonded one by one through the first connecting piece and the second connecting piece, and then through the locking action of the locking assembly on the first clamping body 1 and the second clamping body 2, the first clamping body 1 presses the first connecting piece and the second clamping body 2 presses the second connecting piece, so that the adhesion of the two aligned cutouts of the expansion joint rubber sleeve 7 is more firm and reliable.

[0080] Specifically, as Figure 6As shown, the top of the middle part of the first clamping body 1 is in contact and cooperation with the first connecting piece, that is, the top of the middle part of the first clamping body 1 is used for crimping the first connecting piece. For example, Figure 3 As shown, the first end part and the second end part of the first clamping body 1 are respectively located outside the two end faces of the expansion joint rubber sleeve 7. Among them, the first clamping body 1 can be sequentially divided into a first end part, a middle part and a second end part in a first direction, and the first end part and the second end part of the first clamping body 1 can be respectively a left end part and a right end part;

[0081] For example, Figure 3 As shown, the bottom of the middle part of the second clamping body 2 is in contact and cooperation with the second connecting piece, that is, the bottom of the middle part of the second clamping body 2 is used for crimping the second connecting piece. The first end part and the second end part of the second clamping body 2 are respectively located outside the two end faces of the expansion joint rubber sleeve 7. Among them, the second clamping body 2 can be sequentially divided into a first end part, a middle part and a second end part in a first direction, and the first end part and the second end part of the second clamping body 2 can be respectively a left end part and a right end part;

[0082] The locking assembly includes two locking pieces, and one of the locking pieces is used for locking the first end part of the first clamping body 1 and the first end part of the second clamping body 2, and the other locking piece is used for locking the second end part of the first clamping body 1 and the second end part of the second clamping body 2. That is to say, the top of the middle part of the first clamping body 1 is used for crimping the first connecting piece, and the first end part and the second end part respectively protrude outside the two end faces of the expansion joint rubber sleeve 7. Similarly, the bottom of the middle part of the second clamping body 2 is used for crimping the second connecting piece, and the first end part and the second end part respectively protrude outside the two end faces of the expansion joint rubber sleeve 7. In this way, one locking piece can be used to lock the first end part of the first clamping body 1 and the first end part of the second clamping body 2, and the other locking piece can be used to lock the second end part of the first clamping body 1 and the second end part of the second clamping body 2, so as to facilitate locking of the first clamping body 1 and the second clamping body 2. Of course, this method will not affect the bonding of the two aligned cut surfaces of the expansion joint rubber sleeve 7. In addition, the locking piece can adopt a screw connection assembly, a plug connection assembly or a clamping connection assembly, which will not be elaborated here. Of course, the first clamping body 1 and the second clamping body 2 are distributed in alignment during the process of clamping the first connecting piece and the second connecting piece.

[0083] Furthermore, for example, Figure 3 As shown, the locking piece includes: a guide post 3 and a locking nut 4;

[0084] Among them, for one of the two locking pieces, for example, Figure 5 As shown, the guide post 3 is arranged on the top of the first end part of the first clamping body 1; For example, Figure 7 As shown, a guide hole 2-1 for the guide post 3 to pass through is provided at the first end part of the second clamping body 2; For example, Figure 3As shown, the locking nut 4 is used for threadedly mating with the guide post 3 (threadedly mating with the upper part of the guide post 3) after the guide post 3 passes through the guide hole 2-1 to press the first end of the second clamp body 2;

[0085] For the other locking member of the two locking members, such as Figure 5 As shown, the guide post 3 is arranged on the top of the second end of the first clamp body 1; As Figure 7 As shown, a guide hole 2-1 for the guide post 3 to pass through is provided at the second end of the second clamp body 2; As Figure 3 As shown, the locking nut 4 is used for threadedly mating with the guide post 3 (threadedly mating with the upper part of the guide post 3) after the guide post 3 passes through the guide hole 2-1 to press the second end of the second clamp body 2.

[0086] Among them, this locking member is the screw connection assembly described above. Through the guide post 3 at the top of the first end of the first clamp body 1, the guiding assembly of the first end of the first clamp body 1 and the first end of the second clamp body 2 can be realized, and then through the locking nut 4, the first end of the first clamp body 1 and the first end of the second clamp body 2 can be locked or fastened after the guiding assembly; Similarly, through the guide post 3 at the top of the second end of the first clamp body 1, the guiding assembly of the second end of the first clamp body 1 and the second end of the second clamp body 2 can be realized, and then through the locking nut 4, the second end of the first clamp body 1 and the second end of the second clamp body 2 can be locked or fastened after the guiding assembly, so as to achieve the effect of clamping the first connecting member and the second connecting member.

[0087] That is to say, the ends (i.e., the first end and the second end) of the first clamp body 1 and the second clamp body 2 protrude outside the two end faces of the expansion joint rubber sleeve 7. Through the guide post 3, the guiding assembly of the ends of the first clamp body 1 and the second clamp body 2 can be realized, and then through the locking nut, the guiding assembly of the ends of the first clamp body 1 and the second clamp body 2 can be locked or fastened. This method is not only convenient for the disassembly and assembly of the fixture assembly, but also convenient for the operation of the fixture assembly. In addition, to improve the accuracy of the guiding assembly of the ends of the first clamp body 1 and the second clamp body 2, such as Figure 3 As shown, each locking member can adopt two groups of guide posts 3 and locking nuts 4; Among them, as Figure 5 As shown, that is, the number of guide posts 3 at the top of the first end of the first clamp body 1 can be two, and the number of guide posts 3 at the top of the second end can be two. Correspondingly, as Figure 7 As shown, the number of guide holes 2-1 at the first end of the second clamp body 2 can be two, and the number of guide holes 2-1 at the second end can also be two. Of course, the number of locking nuts 4 required is four.

[0088] Furthermore, as Figure 5As shown in the figure, the locking assembly further includes two gaskets 12. One of the gaskets 12 is sleeved on the guide post 3 at the top of the first end of the first clamp body 1 and is located at the top of the first end of the first clamp body 1. The other gasket 12 is sleeved on the guide post 3 at the top of the second end of the first clamp body 1 and is located at the top of the second end of the first clamp body 1. Among them, the thickness of the gasket 12 is greater than the thickness of the expansion joint rubber sleeve 7 and less than the sum of the thicknesses of the first connecting piece, the expansion joint rubber sleeve 7 and the second connecting piece. In this way, after the locking nuts 4 on both sides lock and press the second clamp body 2, it can prevent the expansion joint rubber sleeve 7 from being over-pressed and damaged. Among them, the gasket 12 is sleeved and welded on the guide post 3. If the thickness of the expansion joint rubber sleeve 7 is 10 mm, the thickness of the gasket 12 can be selected as 11.5 mm. Of course, the number of gaskets 12 also corresponds to the number of guide posts 3 on the corresponding side one by one.

[0089] In this solution, as Figure 6 shown, the first connecting piece includes a first connecting plate 8, as Figure 5 shown, the second connecting piece includes a second connecting plate 6. Among them, the first connecting plate 8 and the second connecting plate 6 can adopt rubber connecting pieces;

[0090] The middle part of the first connecting plate 8 is a corrugated structure and is used to fit the inner wall of the middle corrugated part 7-2 of the expansion joint rubber sleeve 7 (as Figure 5 shown), so that the first connecting plate 8 can be more closely bonded to the inner wall at the two aligned cutouts of the expansion joint rubber sleeve 7. Of course, the first part of the first connecting plate 8 can be adhesively bonded to the first flat part 7-1 of the expansion joint rubber sleeve 7, and the second part can be adhesively bonded to the second flat part 7-3 of the expansion joint rubber sleeve 7. As Figure 5 shown, the middle part of the second connecting plate 6 is a corrugated structure and is used to fit the outer wall of the middle corrugated part 7-2 of the expansion joint rubber sleeve 7, so that the second connecting plate 6 can be more closely bonded to the outer wall at the two aligned cutouts of the expansion joint rubber sleeve 7. Of course, the first part of the second connecting plate 6 can be adhesively bonded to the first flat part 7-1 of the expansion joint rubber sleeve 7, and the second part can be adhesively bonded to the second flat part 7-3 of the expansion joint rubber sleeve 7. In this way, it is convenient for the first connecting piece to be more closely bonded to the inner wall at the two aligned cutouts of the expansion joint rubber sleeve 7, and the second connecting piece to be more closely bonded to the outer wall at the two aligned cutouts of the expansion joint rubber sleeve 7, so that the covering and bonding of the inner and outer walls of the expansion joint rubber sleeve 7 at the seam has a better sealing effect;

[0091] As Figure 5 shown, a corrugated protrusion 1-1 is provided at the top of the middle part of the first clamp body 1 and is used to fit and adhere to the middle part of the first connecting plate 8. Among them, as Figure 6As shown, the corrugated protrusions 1-1 are distributed on the top of the central part of the central portion of the first clamping body 1, which facilitates the complete crimping of the central part of the first connecting plate 8 to the inner wall corresponding to the middle corrugated portion 7-2 of the two aligned cutouts of the expansion joint rubber sleeve 7. Of course, the first part (such as the left part) of the middle part of the first clamping body 1 can be fitted and adhered to the first part of the first connecting plate 8, and the second part (such as the right part) can be fitted and adhered to the second part of the first connecting plate 8; as Figure 8 As shown, a corrugated groove 2-2 is formed at the bottom of the middle part of the second clamping body 2 and is used for fitting and adhering to the middle part of the second connecting plate 6. Among them, as Figure 8 As shown, the corrugated groove 2-2 is distributed at the bottom of the central part of the middle part of the second clamping body 2, which facilitates the complete crimping of the middle part of the second connecting plate 6 to the outer wall corresponding to the middle corrugated portion 7-2 of the two aligned cutouts of the expansion joint rubber sleeve 7. Of course, the first part (such as the left part) of the middle part of the second clamping body 2 can be fitted and adhered to the first part of the second connecting plate 6, and the second part (such as the right part) can be fitted and adhered to the second part of the second connecting plate 6. In this way, it is convenient to make the first connecting member fit and crimp more closely to the inner wall of the two aligned cutouts of the expansion joint rubber sleeve 7, and the second connecting member fit and crimp more closely to the outer wall of the two aligned cutouts of the expansion joint rubber sleeve 7, so that the covering and bonding of the inner and outer walls of the seam of the expansion joint rubber sleeve 7 has a better crimping effect, especially the covering and bonding of the inner and outer walls of the seam of the expansion joint rubber sleeve 7 corresponding to the middle corrugated portion 7-2 has a better crimping effect.

[0092] Specifically, as Figure 6 As shown, a first positioning groove 1-2 and a second positioning groove are further formed at the top of the middle part of the first clamping body 1;

[0093] The first positioning groove 1-2 is located between the corrugated protrusion 1-1 and the first end of the first clamping body 1 and is used for positioning and placing the first flat part 7-1 of the expansion joint rubber sleeve 7 and the first part of the first connecting plate 8; among them, the first positioning groove 1-2 is located at the top of the first part of the middle part of the first clamping body 1;

[0094] The second positioning groove is located between the corrugated protrusion 1-1 and the second end of the first clamping body 1 and is used for positioning and placing the second flat part 7-3 of the expansion joint rubber sleeve 7 and the second part of the first connecting plate 8. Among them, the second positioning groove is located at the top of the second part of the middle part of the first clamping body 1. Such a design of this solution facilitates the quick contact and cooperation between the top of the first clamping body 1 and the first connecting plate 8, and also facilitates the limiting effect on the two end faces of the expansion joint rubber sleeve 7.

[0095] Furthermore, as Figure 2As shown, the fixture assembly further includes two fixing components, and one of the fixing components is disposed on the first side surface of the first clamping body 1 and is used to fix the first part of the first side of the expansion joint rubber sleeve 7 at the two aligned cutouts, and the other fixing component is disposed on the second side surface of the first clamping body 1 and is used to fix the second part of the second side of the expansion joint rubber sleeve 7 at the two aligned cutouts; wherein, the first side surface and the second side surface of the first clamping body 1 are distributed oppositely, and the opposite direction is perpendicular to the first direction.

[0096] Wherein, as Figure 2 shown, the first side surface of the first clamping body 1 can be the front side surface, and the second side surface can be the rear side surface. Of course, as described above, the first end part of the first clamping body 1 can be the left end part, and the second end part can be the right end part. Correspondingly, one of the two fixing components can be disposed on the front side surface of the first clamping body 1 and is used to fix the first part of the front side of the expansion joint rubber sleeve 7 at the two aligned cutouts, and the other fixing component can be disposed on the rear side surface of the first clamping body 1 and is used to fix the second part of the rear side of the expansion joint rubber sleeve 7 at the two aligned cutouts; that is, the front side part and the rear side part of the seam of the expansion joint rubber sleeve 7 are respectively fixed by the two fixing components, so that when bonding the inner and outer walls of the seam of the expansion joint rubber sleeve 7, it can play an auxiliary fixing role on the two side parts of the seam of the expansion joint rubber sleeve 7, avoiding the force on the bonding part (seam) of the expansion joint rubber sleeve 7, and thus facilitating better bonding and crimping of the inner and outer walls of the seam of the expansion joint rubber sleeve 7; of course, the first part and the second part of the expansion joint rubber sleeve 7 are located on both sides of the seam of the expansion joint rubber sleeve 7.

[0097] Furthermore, the fixing component includes: a support plate assembly and a pressing plate assembly; that is, each fixing component includes the above-mentioned support plate assembly and pressing plate assembly;

[0098] For one of the two fixing components, as Figure 6 shown, the support plate assembly is disposed on the first side surface of the first clamping body 1 and is used to support the inner wall of the first part of the expansion joint rubber sleeve 7; the pressing plate assembly is disposed on the first side surface of the first clamping body 1 and is used to press the outer wall of the first part of the expansion joint rubber sleeve 7.

[0099] For the other of the two fixing components, as Figure 6 shown, the support plate assembly is disposed on the second side surface of the first clamping body 1 and is used to support the inner wall of the second part of the expansion joint rubber sleeve 7; the pressing plate assembly is disposed on the second side surface of the first clamping body 1 and is used to press the outer wall of the second part of the expansion joint rubber sleeve 7. That is to say, each fixing component adopts the way of supporting and pressing to realize the fixing of the first part or the second part of the expansion joint rubber sleeve 7. Of course, the fixing component can also adopt a clamping component to realize the clamping and fixing of the first part and the second part of the expansion joint rubber sleeve 7, which will not be elaborated here.

The two cushion plates 16 are respectively arranged at the bottoms of the first end and the second end of the pressing plate 9. Of course, the two cushion plates 16 can be respectively welded to the bottoms of the first end and the second end of the pressing plate 9, and the two cushion plates 16 can be respectively fixed to the two first ear plates 11 through hexagon socket head cap screws 10, so as to realize the installation of the pressing plate assembly between the two first ear plates 11. The first part and the second part of the middle part of the pressing plate 9 are used to respectively press the outer walls of the first straight part 7-1 and the second straight part 7-3 of the first part of the expansion joint rubber sleeve 7. A corrugated avoidance groove is arranged at the bottom of the middle part, for avoiding the middle corrugated part of the first part of the expansion joint rubber sleeve 7; This solution is designed in this way, which can facilitate the effective fixation of the first part of the expansion joint rubber sleeve 7, and this fixation method is more convenient; Of course, like the first clamp body 1 or the second clamp body 2, the pressing plate 9 can be sequentially divided into a first end, a middle part and a second end along the first direction, and the middle part of the pressing plate 9 can be sequentially divided into a first part, a middle part and a second part;

[0104] For the other of the two fixing assemblies, asFigure 6 As shown, two support plates 14 are respectively arranged on the second side surface of the middle part of the first clamp body 1, and are used to respectively support the inner walls of the first straight part 7-1 and the second straight part 7-3 of the second part of the expansion joint rubber sleeve 7; among them, as Figure 6 shown, two support plates 14 are respectively arranged on the second side surfaces of the first part and the second part of the middle part of the first clamp body 1, and are used to respectively support the inner walls of the first straight part 7-1 and the second straight part 7-3 of the second part of the expansion joint rubber sleeve 7; as Figure 2 shown, the pressing plate assembly is arranged between the two second ear plates 13, and is used to press the outer walls of the first straight part 7-1 and the second straight part 7-3 of the second part of the expansion joint rubber sleeve 7. Among them, as described above, the pressing plate assembly includes: a pressing plate 9 and two cushion plates 16. The two cushion plates 16 are respectively arranged at the bottoms of the first end and the second end of the pressing plate 9. Of course, the two cushion plates 16 can be respectively welded to the bottoms of the first end and the second end of the pressing plate 9. The two cushion plates 16 can be respectively fixed to the two second ear plates 13 through hexagon socket head cap screws 10, so as to realize the installation of the pressing plate assembly between the two second ear plates 13. The first part and the second part of the middle part of the pressing plate 9 are used to respectively press the outer walls of the first straight part 7-1 and the second straight part 7-3 of the second part of the expansion joint rubber sleeve 7. A corrugated avoidance groove is arranged at the bottom of the middle part, which is used to avoid the middle corrugated part of the first part of the expansion joint rubber sleeve 7; similarly, designed in this way, the effective fixation of the second part of the expansion joint rubber sleeve 7 can be facilitated, and this fixation method is more convenient.

[0105] In addition, it should also be noted that the first clamp body 1 (inner clamping plate) and the second clamp body 2 (outer clamping plate) can be machined from a whole piece of steel. As Figure 5 shown, the first handles 15 are welded on both sides of the first clamp body 1, which is convenient for carrying and moving the first clamp body 1, and the two first handles are fixed on the outer shell of the busbar through straps; as Figure 7 shown, the second handle 5 is welded on the top of the second clamp body 2, which is convenient for carrying and moving the second clamp body 2, and two relief grooves 2-3 are also opened on the top of the second clamp body 2, which is convenient for realizing the light weight of the second clamp body 2.

[0106] In addition, to better understand the device provided by this solution for bonding the expansion joint rubber sleeve of the nuclear power generator closed busbar, its working process is described as follows:

[0107] Step 1, fix the inner clamping plate (the first clamp body 1) above the outer diameter of φ1450 of the busbar shell with straps;

[0108] Step 2, stick the double-sided tape along the length direction of the inner clamping plate on the top surface of the middle part of the inner clamping plate;

[0109] Step 3: Tear off the protective film of the double-sided tape, and then stick the polished inner connecting plate (the first connecting plate, which can be made of rubber sheet) with a thickness of 1 mm onto the double-sided tape of the inner splint according to the shape of the inner splint, noting that the polished surface of the inner connecting plate faces upward;

[0110] Step 4: Place the aluminum foil paper on the 1-mm inner connecting plate according to the shape of the inner splint;

[0111] Step 5: Fix the aluminum foil paper with tape; among them, the purpose of using the aluminum foil paper is to prevent the vulcanized rubber from penetrating onto the 1-mm thick inner connecting plate during bonding;

[0112] Step 6: Grind both the front and back sides of the bonding part (two aligned cuttings) of the rubber sleeve of the generator enclosed busbar expansion joint;

[0113] Step 7: Align the left and right cuttings of the rubber sleeve of the generator enclosed busbar expansion joint and place it on the inner splint, and then fix the parts on both sides of the seam of the expansion joint rubber sleeve one by one through two fixing components to avoid the expansion joint rubber sleeve from being stressed;

[0114] Step 8: Apply the first coat of glue (including the cutting) on the rough surface of the two aligned cuttings of the rubber sleeve of the generator enclosed busbar expansion joint, and then apply the second coat of glue (including the cutting) after the glue dries until it is not sticky;

[0115] Step 9: After applying the second coat of glue, two people lift the rubber sleeve of the generator enclosed busbar expansion joint respectively and jointly apply force in the direction of the cutting to align it (since the expansion joint rubber sleeve may have tensile deformation, which may cause gaps at the two cuttings, so it is necessary to lift the two cuttings of the expansion joint rubber sleeve manually to achieve alignment;

[0116] Step 10: Stick the applied outer connecting plate (the second connecting plate, which can be made of rubber sheet) onto the outer wall of the two aligned cuttings according to the shape of the rubber sleeve of the generator enclosed busbar expansion joint;

[0117] Step 11: After the outer connecting plate is bonded, fix the rubber sleeve of the generator enclosed busbar expansion joint with the bonded outer connecting plate by using the outer splint (the second clamp body 2), and tighten the four lock nuts until they reach the end;

[0118] Step 12: Let the inner splint and the outer splint press for 24 hours, then the outer splint can be loosened, and then the bonding work of the 1-mm inner connecting plate can be started again;

[0119] Step 13: Before bonding the inner connecting plate, tear off the aluminum foil paper, apply the first coat of glue on the 1-mm thick inner connecting plate, and then apply the second coat of glue after it is not sticky;

[0120] Step 14: Apply the first layer of glue to the roughened area inside the rubber sleeve of the generator closed bus expansion joint (the inner walls of the two aligned cutouts). After it is no longer sticky, apply the second layer of glue. After applying the two layers of glue, move the rubber sleeve of the generator closed bus expansion joint to the inner clamping plate, align it with the 1-mm-thick inner connecting plate on the inner clamping plate, then fix and press it tightly with the outer clamping plate and maintain the pressing force for 6 hours. Then loosen the lock nut, remove and disassemble the inner and outer clamping plates, thus completing the internal and external bonding work of the rubber sleeve of the generator closed bus expansion joint;

[0121] Step 15: Move the bonded rubber sleeve of the generator closed bus expansion joint to a suitable position at the φ1650-mm bus housing. Gradually lift the edge of the rubber sleeve of the generator closed bus expansion joint, squeeze the glass glue into the rubber sleeve of the expansion joint by 30 - 40 mm (squeezing in a full circle), and then tighten the expansion joint rubber sleeve with a hoop. Thus, the fixed installation of the rubber sleeve of the generator closed bus expansion joint is completed.

[0122] Note: When fixing with the outer clamping plate, two people should always forcefully squeeze the two cutouts to ensure that the cutouts are aligned and there are no gaps before fixing the outer clamping plate. After the outer clamping plate is fixed, the two people can let go, and the external bonding work of the rubber sleeve of the generator closed bus expansion joint is completed.

[0123] In summary, the present utility model discloses a device for bonding the rubber sleeve of a nuclear power generator closed bus expansion joint, belonging to the technical field of fixture devices. The device includes an inner clamping plate and an outer clamping plate. The two ends of the inner clamping plate and the outer clamping plate are assembled through guide columns and fixed by lock nuts. The rubber sleeve of the generator closed bus expansion joint is bonded through an inner connecting plate and an outer connecting plate, and then the inner clamping plate and the outer clamping plate press the inner connecting plate and the outer connecting plate one by one, so that the cured expansion joint rubber sleeve is bonded more firmly; pressing plates are provided on the front and back sides of the inner clamping plate, and the pressing plates are fixed at the ear plates of the inner clamping plate through inner hexagon nuts, which are used to fix the parts on both sides of the seam of the expansion joint rubber sleeve to avoid the bonding part of the expansion joint rubber sleeve from being stressed; the present utility model also welds gaskets with a thickness of 11.5 mm at the guide columns at both ends of the inner clamping plate. The thickness of the gasket is greater than the thickness of the expansion joint rubber sleeve to be press-bonded and fixed by 10 mm, so as to avoid excessive stress on the expansion joint rubber sleeve after the nuts at both ends of the outer clamping plate are tightened, damaging the expansion joint rubber sleeve; of course, this fixture device is convenient for disassembly and installation, simple and convenient to operate. After the bonded rubber sleeve of the generator closed bus expansion joint is press-fixed by this fixture device, the bonding effect is good.
