Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical maintenance, and more specifically relates to a condenser plug disassembly and assembly tool. Background Art

[0002] There are two situations for blocking titanium tubes in nuclear power plant condensers: one is preventive blocking, and the other is to deal with defective tubes. Both purposes prevent seawater from entering the titanium tubes. Blockage will affect the operation of the unit. If seawater enters the steam side of the condenser through the defective tube, it will cause the unit to shut down.

[0003] The plugs with problems will be replaced every time the nuclear power plant is shut down for maintenance. All plugs need to be replaced every 10 years for major overhaul. There are currently no suitable tools for replacement. When using old tools to remove the plugs, the force cannot be applied evenly, which can easily damage the plugs and even make them unable to be pulled out. In addition, it is easy to damage the tube sheet and affect the sealing welding. Utility Model Content

[0006] In the above scheme, the disassembly tool includes a disassembly rod, a first stopper and a hammer. The tap section on the disassembly rod is used to tap the plug so that the disassembly rod and the plug are connected to each other. The hammer is used to hit the first stopper in the disassembly direction so that the disassembly rod drives the plug to move in the disassembly direction, thereby removing the plug. When the disassembly tool is used to disassemble the plug, the force on the plug is uniform, and during disassembly, the plug does not contact the tube sheet and will not damage the tube sheet.

[0007] Optionally, the first limiting member includes a connecting portion and a limiting portion, the connecting portion is connected to the connecting section, the limiting portion is formed by radially extending outward from the connecting portion, and the limiting portion is used to axially limit the hammer.

[0008] In the above scheme, by setting the first limiter as a connecting part and a limiter, the connection between the first limiter and the connecting section is achieved. At the same time, the first limiter has a limiting function for the hammer, and the limiter bears the impact of the hammer.

[0009] Optionally, one of the connecting section and the connecting portion has an external thread, and the other has an internal thread, so that the connecting section and the connecting portion are threadedly connected.

[0020] In the above scheme, when pre-expanding the plug, the first insertion part of the first installation tool is first inserted into the inner cavity of the female head, and the end of the first stop part facing the first insertion part abuts against the end face of the female head. In this way, the length of the first insertion part inserted into the female head is determined, and then the sub-head is installed into the interior of the female head. During the process of inserting the sub-head into the female head, the position of the insertion end of the sub-head will be restricted by the first insertion part, so the insertion depth of the sub-head can be controlled to avoid excessive insertion depth of the sub-head.

[0021] Optionally, the condenser plug disassembly and assembly tool also includes a second installation tool, the second installation tool includes a second stop portion and a second insertion portion connected to the second stop portion, the plug has an inner cavity for inserting the second insertion portion, and the second installation tool is used to install the plug to the tube sheet.

The plug is evenly stressed during the installation process, and under the shielding effect of the second stop portion, it will not contact the end of the tube body when hammering, thereby protecting the tube sheet.

[0023] Optionally, the second installation tool further includes a hammering portion, wherein the hammering portion and the second insertion portion are respectively connected to opposite sides of the second stop portion, and a cross-sectional area of ​​the hammering portion is gradually increased in a direction away from the second stop portion.

[0024] In the above scheme, when the second installation tool is hammered, the impact force of the hammering tool acts on the side of the hammering part away from the second stopper, which is called the hammering side. The arrangement of the hammering part makes the hammering side farther from the tube sheet, and the area of ​​the hammering side at the end away from the tube sheet is larger. When the distance between adjacent plugs is close and the hammering tool is large, the arrangement of the hammering part does not affect the installation of adjacent plugs, avoiding collision with adjacent plugs during hammering.

DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] There are two situations for blocking titanium tubes in nuclear power plant condensers: one is preventive blocking, and the other is to deal with defective tubes. Both purposes prevent seawater from entering the titanium tubes. Blockage will affect the operation of the unit. If seawater enters the steam side of the condenser through the defective tube, it will cause the unit to shut down.

[0038] The plugs with problems will be replaced every time the nuclear power plant is shut down for maintenance. All plugs need to be replaced every 10 years for major overhaul. There are currently no suitable tools for replacement. When using old tools to remove the plugs, the force cannot be applied evenly, which can easily damage the plugs and even make them unable to be pulled out. In addition, it is easy to damage the tube sheet and affect the sealing welding.

[0039] In order to solve the above technical problems, the utility model proposes a condenser plug disassembly and assembly tool, including a disassembly tool 10, the disassembly tool 10 includes a disassembly rod 11, a first stopper 12 connected to one end of the disassembly rod 11, and a hammer 13 that can move on the disassembly rod 11. When disassembling the plug 40, the tap section 111 at one end of the disassembly rod 11 taps the plug 40 to connect the plug 40 to the disassembly rod 11, and then the hammer 13 hits the first stopper 12 along the disassembly direction, and under the impact, the disassembly rod 11 and the plug 40 are disengaged together, completing the disassembly of the plug 40. This plug disassembly method is simple and will not damage the tube sheet.

[0040] The condenser plug disassembly and assembly tool provided in the embodiment of the utility model is now described.

[0041] Please also read Figures 1 to 3 The condenser plug disassembly tool includes a disassembly tool 10, which is used to disassemble the plug 40. The plug 40 is installed inside the tube sheet. Specifically, the tube sheet is composed of a plurality of tube bodies arranged in an array, and one plug 40 is correspondingly installed inside one tube body. The plug 40 is generally interference-fitted inside the tube body, so it is difficult to disassemble the plug 40 inside the tube body.

[0042] The disassembly tool 10 includes a disassembly rod 11 , a first position-limiting member 12 and a hammer 13 . The first position-limiting member 12 is connected to one end of the disassembly rod 11 .

[0043] The disassembly rod 11 is used to extend into the tube sheet, or extend into the inside of the plug 40, and is connected to the plug 40. The disassembly rod 11 includes a tap section 111, a transition section 112 and a connection section 113 which are connected in sequence.

[0044] The disassembly rod 11 is in the shape of a rod, and includes a tap section 111, a transition section 112, and a connecting section 113 which are connected in sequence. The tap section 111 is used to connect with the plug 40. Specifically, the surface of the tap section 111 has rolling teeth, and after the tap section 111 contacts the plug 40, the disassembly rod 11 is rotated to tap the plug 40, thereby connecting the plug 40 and the tap section 111 to each other. The connecting section 113 is connected to the first stopper 12, so that the tap section 111 and the first stopper 12 are respectively located at opposite ends of the disassembly tool 10. The transition section 112 is used to connect the tap section 111 and the connecting section 113. The provision of the transition section 112 can extend the length of the disassembly rod 11, so that the disassembly tool can adapt to a wider range of working conditions.

[0045] The first stopper 12 axially limits the striker 13. The length direction of the disassembly rod 11 is parallel to the axial direction, and the direction perpendicular to the axial direction can be called the radial direction. Specifically, when disassembling the plug 40, the striker 13 is required to strike the first stopper 12 to transmit the impact force to the disassembly rod 11 and the plug 40, so that the plug 40 can be removed from the tube sheet.

[0046] The hammer 13 is sleeved on the outer circumference of the connecting section 113 , and the hammer 13 can move along the axial direction of the disassembly rod 11 . When the hammer 13 moves to the first limit member 12 , it collides with the first limit member 12 , converting the kinetic energy of the hammer 13 into an impact force on the first limit member 12 .

[0047] When removing the plug 40, the tap section 111 of the disassembly rod 11 approaches the plug 40, and the disassembly rod 11 is rotated to make the tap section 111 tap the plug 40, so that the tap section 111 is embedded in the plug 40. After the tapping length reaches a predetermined value, the hammer 13 is moved in the disassembly direction to hit the first limiter 12, so that the disassembly rod 11 drives the plug 40 to escape from the pipe body in the disassembly direction. The disassembly direction of the plug 40 and the installation direction of the plug 40 are both parallel to the axial direction.

[0048] The condenser plug disassembly tool in the above embodiment includes a disassembly tool 10 for disassembling the plug 40, the disassembly tool 10 includes a disassembly rod 11, a first stopper 12 and a hammer 13, the tap section 111 on the disassembly rod 11 is used to tap the plug 40 so that the disassembly rod 11 and the plug 40 are connected to each other, and the hammer 13 is used to hit the first stopper 12 in the disassembly direction so that the disassembly rod 11 drives the plug 40 to move in the disassembly direction, thereby disassembling the plug 40. When the disassembly tool 10 is used to disassemble the plug 40, the force on the plug 40 is uniform, and during disassembly, the tube sheet is not contacted and the tube sheet is not damaged.

[0049] In some embodiments of the present invention, please refer to Figure 1 and Figure 2 The first stopper 12 includes a connecting portion 121 and a stopper 122. The connecting portion 121 is connected to the connecting section 113. The stopper 122 is formed by the connecting portion 121 extending radially outward. The stopper 122 is used to axially stop the hammer 13. It can be understood that the stopper 122 is connected to one end of the connecting portion 121, and the connecting section 113 is connected to the other end of the connecting portion 121, so as to realize the connection between the connecting section 113 and the first stopper 12. The stopper 122 is formed by the connecting portion 121 extending radially outward, and the outer dimensions of the stopper 122 are greater than the outer dimensions of the connecting portion 121.

[0050] By configuring the first limiting member 12 as a connecting portion 121 and a limiting portion 122 , the connection between the first limiting member 12 and the connecting section 113 is achieved. Meanwhile, the first limiting member 12 has a limiting function for the hammer 13 , and the limiting portion 122 bears the impact of the hammer 13 .

[0051] In some embodiments, the connecting portion 121 and the limiting portion 122 are integrally formed, so that the first limiting member 12 is an integrated structure and does not need to be installed.

[0052] In some embodiments, the limiting portion 122 is disc-shaped. Firstly, it is convenient for the user to hold the first limiting member 12 and install the first limiting member 12 to the connecting section 113. Secondly, it can withstand the impact of the hammer 13 at various locations in the circumferential direction, so that the force on the limiting portion 122 is more balanced.

[0053] In some embodiments, see Figure 1 and Figure 2, one of the connecting section 113 and the connecting portion 121 has an external thread, and the other has an internal thread, so that the connecting section 113 and the connecting portion 121 are threadedly connected. It can be understood that the first stopper 12 and the disassembly rod 11 are threadedly connected, and the threaded connection method is simple and does not require installation tools. Specifically, this embodiment includes the following two situations: the connecting section 113 has an external thread, the connecting portion 121 has an internal thread, and the connecting portion 121 is at least partially located inside the connecting section 113; or, the connecting section 113 has an internal thread, the connecting portion 121 has an external thread, and the connecting section 113 is at least partially located inside the connecting portion 121.

[0054] In other embodiments, the first limiting member 12 is formed by extending radially outward from one end of the connecting section 113 away from the transition section 112 .

[0055] Optionally, the first position-limiting member 12 is integrally formed with the connecting section 113. Alternatively, the first position-limiting member 12 is fixed to the connecting section 113 by welding or the like.

[0056] In some embodiments of the present invention, please refer to Figure 1 and Figure 2 A handle structure 114 is fixedly arranged on the periphery of the transition section 112. The arrangement of the handle structure 114 facilitates the operator to rotate the disassembly rod 11 and avoids the occurrence of hand slipping and the like. The handle structure 114 is arranged on the periphery of the transition section 112, and may be a part of the circumferential surface of the transition section 112, or may be formed by the circumferential surface of the transition section 112 extending radially outward.

[0057] Optionally, the cross section of the handle structure 114 is hexagonal, and when rotating the disassembly rod 11, two fingers can be pressed on two surfaces of the hexagon respectively, which is convenient for applying force to the disassembly rod 11. The disassembly rod 11 can also be rotated by using an inner hexagon wrench in conjunction with the handle structure 114.

[0058] Optionally, the cross-section of the handle structure 114 is a quadrilateral, a pentagon, etc., which can facilitate the rotation of the disassembly rod 11.

[0059] Optionally, the handle structure 114 is a texture structure arranged on the periphery of the transition section 112, such as a convex or concave pattern, an array structure, etc. In this way, the friction between the hand and the handle structure 114 can be increased, making the disassembly rod 11 easier to rotate.

[0060] In some embodiments of the present invention, please refer to Figure 1 and Figure 2The disassembly tool 10 also includes a second limit member 14, and the position of the second limit member 14 is adjustably arranged on the transition section 112. The second limit member 14 is movably arranged on the transition section 112, and the positions of the second limit member 14 and the transition section 112 can be adjusted as needed. Among them, the second limit member 14 can move along the axial direction of the transition section 112 to adjust the relative position of the second limit member 14 and the transition section 112. The hammer 13 is arranged between the first limit member 12 and the second limit member 14, so the stroke of the hammer 13 is the distance between the limit portions 122 of the first limit member 12 and the second limit member 14 to adapt to different disassembly spaces and disassembly scenarios.

[0061] By providing the second position-adjustable limiter 14 , the distance between the first position-limiter 12 and the second position-limiter 14 can be adjusted, that is, the moving stroke of the hammer 13 can be adjusted, and the maximum kinetic energy that the hammer 13 can obtain can be adjusted.

[0062] In some embodiments, see Figure 1 and Figure 2 The second stopper 14 is a nut, and a matching thread is provided on the outer periphery of the transition section 112. The second stopper 14 is threadedly connected to the transition section 112. When the second stopper 14 is rotated, the second stopper 14 also moves along the axial direction of the transition section 112 to adjust the position of the second stopper 14.

[0063] Optionally, the second position-limiting member 14 is a structure such as a hexagonal nut, which facilitates rotational adjustment of the second position-limiting member 14 .

[0064] In some embodiments, the second limit member is a retaining spring, and the transition section 112 has multiple retaining grooves along its axial direction. The retaining spring is selectively engaged in one of the retaining grooves, and the position of the second limit member can also be changed to adjust the movement stroke of the hammer 13.

[0065] In some embodiments of the present invention, please refer to Figure 3 and Figure 4 The condenser plug disassembly and assembly tool also includes a first installation tool 20, which includes a first stop portion 22 and a first insertion portion 21 connected to the first stop portion 22. The plug 40 includes a sub-head 42 and a female head 41. The female head 41 has an inner cavity for inserting the sub-head 42. The first installation tool 20 is used to limit the insertion depth of the sub-head 42. The sub-head 42 and the first insertion portion 21 are respectively inserted into the inner cavity from both ends of the female head 41.

[0066] The first installation tool 20 is used to pre-expand the new plug 40 in preparation for installing the plug 40 on the tube sheet. Specifically, the plug 40 includes a sub-head 42 and a female head 41. The female head 41 is arranged in a sleeve shape, that is, the female head 41 has an inner cavity and is hollow. One end of the sub-head 42 extends into the interior of the female head 41. The outer circumferential wall of the sub-head 42 and the inner circumferential wall of the female head 41 are arranged in an interference fit. The length of the axial overlap between the sub-head 42 and the female head 41 is called the insertion depth of the sub-head 42. The first installation tool 20 is used to limit the insertion depth of the sub-head 42.

[0067] When pre-expanding the plug 40, firstly extend the first insertion portion 21 of the first installation tool 20 into the inner cavity of the female head 41, and the end of the first stop portion 22 facing the first insertion portion 21 abuts against the end surface of the female head 41, so that the length of the first insertion portion 21 extending into the female head 41 is determined, and then the sub-head 42 is installed into the interior of the female head 41. During the process of inserting the sub-head 42 into the female head 41, the position of the inserted end of the sub-head 42 will be restricted by the first insertion portion 21, so the insertion depth of the sub-head 42 can be controlled to avoid the insertion depth of the sub-head 42 being too large.

[0068] In some embodiments, the cross section of the first installation tool 20 is T-shaped, and the first insertion portion 21 is located at the center of the first stop portion 22 , so that the first stop portion 22 forms a stop for each position of the end surface of the female connector 41 .

[0069] Optionally, the first stopper 22 is a circular, square, polygonal or other structure.

[0070] In some embodiments of the present invention, please refer to Figure 5 The condenser plug disassembly and assembly tool also includes a second installation tool 30, which includes a second stopper 32 and a second insertion portion 31 connected to the second stopper 32. The plug 40 has an inner cavity for inserting the second insertion portion 31. The second installation tool 30 is used to install the plug 40 to the tube sheet.

[0071] The second installation tool 30 is used to install the plug 40 to the tube sheet, which can prevent the tube sheet from being damaged when installing the plug 40, and can make the plug 40 be evenly stressed when installed, so that the plug 40 is installed in place. The plug 40 has an inner cavity, and the inner cavity into which the second insertion portion 31 is inserted can be the inner cavity of the sub-head 42 or the inner cavity of the female head 41. The second stopper 32 is used to abut against the end face of the plug 40.

[0072] When installing the pre-expanded plug 40 to the tube body corresponding to the tube sheet, first align the plug 40 with the hole of the tube body, and then hammer the side of the second stopper 32 away from the second insertion portion 31 to gradually insert the plug 40 into the interior of the tube body. The plug 40 is evenly stressed during the installation process, and under the shielding effect of the second stopper 32, it will not contact the end of the tube body when hammered, thereby protecting the tube sheet.

[0073] In some embodiments, the cross section of the second installation tool 30 is T-shaped, and the second insertion portion 31 is located at the center of the second stop portion 32, so that the second stop portion 32 blocks all circumferential positions of the tube body.

[0074] Optionally, the second stopper 32 is a circular, square, polygonal or other structure.

[0075] In some embodiments, see Figure 5 The second installation tool 30 also includes a hammering part 33. The hammering part 33 and the second insertion part 31 are respectively connected to the opposite sides of the second stopper 32. The cross-sectional area of ​​the hammering part 33 is gradually increased in the direction away from the second stopper 32. The second insertion part 31, the second stopper 32 and the hammering part 33 are connected in sequence. When the second installation tool 30 is hammered, the impact force of the hammering tool acts on the side of the hammering part 33 away from the second stopper 32, which is called the hammering side. The setting of the hammering part 33 makes the hammering side farther from the tube sheet, and the area of ​​the hammering side at the end away from the tube sheet is larger. When the distance between adjacent plugs is close and the hammering tool is large, the setting of the hammering part 33 does not affect the installation of adjacent plugs, avoiding collision with adjacent plugs during hammering.

[0076] Optionally, the cross section of the hammering portion 33 gradually increases in a direction away from the stop portion, so that the area of ​​the hammering surface 331 is larger, which facilitates hammering.

[0077] The replacement and disassembly of the condenser plug 40 includes the following three steps: disassembly, pre-expansion and installation. When disassembling the plug 40, use the disassembly tool 10 to remove the plug 40 from the tube sheet. When pre-expanding the plug 40, use the first installation tool 20 to limit the embedding depth between the sub-head 42 and the female head 41. When installing the plug 40 on the tube sheet, use the second installation tool 30 to limit the embedding depth of the plug 40 on the tube sheet and protect the tube sheet.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
