Description

Technical Field

[0001] This invention relates to the field of nuclear industry technology, and in particular to a locking plate deployment device and processing equipment. Background Technology

[0002] To measure the temperature of the reactor core, multiple thermocouples are typically installed. These thermocouples are housed within stainless steel conduits, which guide and protect them. Connecting the conduits to each other or to other structures requires fittings. Specifically, a fitting consists of a fitting body and a nut. The conduit is inserted into the nut, and the nut is tightened onto the fitting body, thus connecting the conduits. To prevent the nut from loosening, some fittings also have locking plates. After the nut is tightened onto the fitting body, the locking plate is welded to the nut, preventing the nut from rotating relative to the fitting body.

[0003] In abnormal situations, the conduit may become bent or deformed. For conduits that are bent beyond correction or damaged conduits, replacement is required. When replacing, the nut connected to the conduit must be removed. Before removing the nut, the locking plate must be opened first. After replacing the nut, the locking plate must be reset. Taking the opening of the locking plate as an example, the relevant technology usually uses a tool with a pointed tip to be inserted between the locking plate and the nut, and then the locking plate is opened by pushing the tool. However, due to the limited tilt angle of the tip, this method can only open the locking plate to a small degree, which affects the subsequent loosening of the nut. Summary of the Invention

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0027] In the description of this invention, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0028] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0029] In the description of this invention, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] This invention applies to fastening assembly 20. For ease of understanding, the basic structure of fastening assembly 20 is first described. In a typical embodiment, fastening assembly 20 includes a nut as a first fastener 21 and a pipe fitting as a second fastener 22. Furthermore, in some embodiments, the connector also includes a limiting member 24, which includes a retaining sleeve. (See reference...) Figure 1 The connector connects the conduit 30 in the following manner: the pipe fitting, which serves as the second fastener 22, has a pipe fitting body and connecting ends (only one end is shown in the figure) connected to both ends of the pipe fitting body, and the connecting end has external threads. The retaining sleeve, which serves as the limiting member 24, is located inside the nut, which serves as the first fastener 21. The metal conduit 30 passes through the retaining sleeve and extends into the connecting end of the pipe fitting. As the nut is tightened, the nut pushes the limiting member 24 to compress the wall of the conduit 30, causing it to deform. At this time, the limiting member 24 holds tightly against the outer wall of the conduit 30 and maintains a fixed connection. The connecting end at the other end of the pipe fitting body is connected to another conduit 30 through another nut, thus realizing the connection of the two conduit sections 30.

[0031] To prevent the nut from accidentally loosening, the fastening assembly 20 also includes a washer 25, see reference. Figure 2 , Figure 3 The gasket 25 includes a locking piece 23, which can be connected to the main body of the gasket 25 as an integral structure. The gasket 25 is located between the first fastener 21 and the second fastener 22, and has a connected state suitable for connection with the first fastener 21, and an unfolded state suitable for rotation of the first fastener 21. Specifically, Figure 2 The locking piece 23 shown is in a connected state. In this state, the locking piece 23 is bent relative to the main body of the gasket 25 and is at least partially attached to or against the adjacent first fastener 21. At this time, the locking piece 23 can be further welded to the first fastener 21 to prevent the first fastener 21 from rotating. Figure 3The locking piece 23 on the right side is in the unfolded state. In this state, the locking piece 23 is parallel or approximately parallel to the main body of the gasket 25. At this time, the sleeve 40 can be sleeved on the outside of the first fastener 21, and the first fastener 21 can be rotated relative to the second fastener 22 through the sleeve 40 to loosen or tighten it. For ease of explanation, the following will use the first fastener 21 as a nut and the second fastener 22 as a pipe fitting as an example.

[0032] As mentioned earlier, when an abnormality causes the conduit 30 to bend or deform, the bent or deformed conduit needs to be replaced. Specifically, this involves removing the weld between the locking plate 23 and the nut using a tool, loosening the nut from the pipe fitting, and separating the old nut from the conduit and pipe fitting. After this process, a new conduit is replaced, and the nut is tightened. The locking plate 23 is then reset and welded to the new nut. Related technologies typically use tools with pointed ends for contact. Figure 2 The gap between the locking plate 23 and the first fastener 21 allows the locking plate 23 to unfold. To facilitate insertion of the tool end into the gap, the angle of the end cannot be too large. This results in the actual tool being unable to push the locking plate 23 to its intended position. Figure 3 The ideal unfolding state shown can usually only achieve... Figure 4 As shown, this state prevents the sleeve 40 from being fitted onto the outside of the nut, thus affecting the rotation of the nut. It should be noted that this application is applicable to scenarios with radiation hazards, such as reactors. To ensure the safety of operators, remote operation using appropriate loosening devices is required. Therefore, this application provides a simple and easily remotely controlled locking plate unfolding device, a locking plate resetting device, and corresponding processing equipment.

[0033] Reference Figure 5 , Figure 6 The diagram shows a perspective view and a top view of the locking plate unfolding device 100 in the first embodiment of the present invention. It includes an unfolding component 110, a first base 120, a first transmission component 130 and a second transmission component 140. The first base 120 serves as the mounting body for mounting the aforementioned unfolding component 110, the first transmission component 130 and the second transmission component 140. The unfolding component 110 is used to unfold the locking plate 23. The first transmission component 130 is used to transmit power to switch between different unfolding parts on the unfolding component 110. The second transmission component 140 is used to transmit power to push the unfolding component 110.

[0034] Reference Figure 7The unfolding assembly 110 includes a main body 113, a first unfolding part 111, and a second unfolding part 112. Both the first unfolding part 111 and the second unfolding part 112 are connected to the main body 113. The first unfolding part 111 is suitable for the initial unfolding of the locking piece 23, and the second unfolding part 112 is suitable for the final unfolding of the locking piece 23. In some specific embodiments, the first unfolding part 111, the second unfolding part 112, and the main body 113 are connected as a single unit.

[0035] The first transmission assembly 130 is driveably connected to the unfolding assembly 110. The first transmission assembly 130 is configured to be driven to move the unfolding assembly 110 relative to the first base 120, so that the first unfolding part 111 or the second unfolding part 112 faces the locking piece 23. Specifically, the first transmission assembly 130 can drive the unfolding assembly 110 to rotate or translate relative to the first base 120. When the unfolding assembly 110 rotates, the first unfolding part 111 or the second unfolding part 112 is positioned along the rotation direction; when the unfolding assembly 110 translates, the first unfolding part 111 or the second unfolding part 112 is positioned along the translation direction. It should be noted that, in this embodiment, "facing the locking piece 23" means that the first unfolding part 111 or the second unfolding part 112 is in a state suitable for pushing the locking piece 23. For example, the end of the first unfolding part 111 is approximately facing the position between the locking piece 23 and the first fastener 21. In some embodiments, the locking tab unfolding device 100 has its own power source, which drives the unfolding component 110 to move through the first transmission component 130 to switch different unfolding parts. In other embodiments, the locking tab unfolding device 100 does not have a power source, but relies on an external power source to drive the unfolding component 110 to move through the first transmission component 130 to switch different unfolding parts. This will be explained in detail in the following embodiments.

[0036] The second transmission assembly 140 is connected to the unfolding assembly 110. The second transmission assembly 140 is configured to be driven to move the unfolding assembly 110 relative to the first base 120, so that the first unfolding part 111 or the second unfolding part 112 pushes the locking piece 23. Specifically, the first transmission assembly 130 can drive the unfolding assembly 110 to translate relative to the first base 120 along the axial direction of the nut to push it. That is, the unfolding assembly 110 and the fastening assembly 20 are distributed along the axial direction of the nut. Similarly, in some embodiments, the locking piece unfolding device 100 has its own power source, which drives the unfolding assembly 110 to move and push the locking piece 23 through the second transmission assembly 140. In other embodiments, the locking piece unfolding device 100 does not have a power source, but relies on an external power source to drive the unfolding assembly 110 to move and push the locking piece 23 through the first transmission assembly 130. This will be explained in detail in the following embodiments.

[0037] It should be noted that in some embodiments, the unfolding component 110 is connected to the first transmission component 130, the first transmission component 130 is connected to the second transmission component 140, and the second transmission component 140 is connected to the first base 120.

[0038] Based on the above structure, the locking plate unfolding device 100 in this embodiment is configured such that when the first unfolding part 111 faces the locking plate 23, the first unfolding part 111 can push the locking plate 23 to open to a first opening degree (e.g., Figure 8 (As shown); and after the locking piece 23 is opened to the first opening degree and the second unfolding part 112 faces the locking piece 23, the second unfolding part 112 can push the locking piece 23 to open to the second opening degree (as shown). Figure 9 As shown), the locking plate 23 is switched from the connected state to the deployed state, with the second opening being greater than the first opening. Thus, by sequentially pushing the first deploying part 111 and the second deploying part 112, the locking plate 23 can be pushed to a state parallel or approximately parallel to the main body of the gasket 25, thereby preventing the locking plate 23 from obstructing the sleeve 40 from engaging the nut. Furthermore, power is transmitted through the first transmission assembly 130 to switch between the first deploying part 111 and the second deploying part 112, and through the second transmission assembly 140 to push the deploying assembly 110, facilitating remote control of the locking plate deployment device 100 by operators to deploy the locking plate 23, thus adapting to working environments such as reactors.

[0039] Based on the first embodiment, in some embodiments of the present invention, reference is made to Figure 7 The main body 113 is rotatably connected to the first base 120. Specifically, the main body 113 is rotatably connected to the first transmission assembly 130 and connected to the first base 120 through the first transmission assembly 130.

[0040] The first transmission assembly 130 is configured to be driven to rotate the unfolding assembly 110 relative to the first base 120, so that the first unfolding part 111 or the second unfolding part 112 faces the locking piece 23. In this way, the first unfolding part 111 and the second unfolding part 112 can be quickly switched, while reducing the space occupied by the unfolding assembly 110 and helping to reduce the size of the locking piece unfolding device 100.

[0041] The first unfolding portion 111 and the second unfolding portion 112 are distributed along the rotation direction, specifically to Figure 7In the illustrated embodiment, the main body 113 is configured as a rotating structure, including a connecting frustum and a connecting shaft disposed on one side of the connecting frustum. The connecting shaft is used for rotatable connection with the first transmission assembly 130. The first unfolding part 111 and the second unfolding part 112 are distributed along the circumferential direction of the connecting frustum. Thus, as the main body 113 rotates, switching between the first unfolding part 111 and the second unfolding part 112 can be achieved. In some specific embodiments, there are two of each of the first unfolding part 111 and the second unfolding part 112, so as to simultaneously unfold the locking pieces 23 on both sides of the gasket 25, thereby improving the unfolding efficiency.

[0042] When the first unfolded portion 111 and the second unfolded portion 112 are distributed along the rotation direction, in some embodiments of the present invention, referring to... Figure 10 Along the rotation direction, the angle α between the central axis of the first unfolding part 111 along the pushing direction and the central axis of the second unfolding part 112 along the pushing direction is less than 90°. Thus, without interference, the unfolding assembly 110 only needs to rotate a small angle to switch between the first unfolding part 111 and the second unfolding part 112. For applications requiring remote control, especially those requiring manual operation, this embodiment can further reduce the workload of operators. Specifically, the angle α can be 30°, 45°, 60°, 70°, etc.

[0043] Based on the first embodiment, in some embodiments of the present invention, reference is made to Figure 7 The first unfolding portion 111 includes a first bottom surface 1111 and a first pushing surface 1112 for abutting against the locking piece 23. The first bottom surface 1111 is parallel to the pushing direction of the first unfolding portion 111. For example, the first pushing surface 1112 is disposed at the end of the first unfolding portion 111 away from the main body portion 113.

[0044] The second unfolding portion 112 includes a second bottom surface 1121 and a second pushing surface 1122 for abutting against the locking piece 23. The second bottom surface 1121 is parallel to the pushing direction of the second unfolding portion 112. For example, the second pushing surface 1122 is disposed at the end of the second unfolding portion 112 away from the main body portion 113.

[0045] In this embodiment, the angle between the first pushing surface 1112 and the first bottom surface 1111 is smaller than the angle between the second pushing surface 1122 and the second bottom surface 1121. Thus, the first unfolding part 111 is suitable for inserting into the small gap between the locking piece 23 and the nut in the connected state, thereby realizing the initial unfolding of the locking piece 23. The second unfolding part 112 is suitable for unfolding the locking piece 23, which has been unfolded to a certain angle, again, and can push the locking piece 23 to unfold to a larger opening.

[0046] In some specific embodiments, reference is made to Figure 7Along the direction away from the main body 113, the distance between the first pushing surface 1112 and the first bottom surface 1111 gradually decreases to form an insertion end 1113 suitable for insertion between the locking piece 23 and the first fastener 21. For example, the first pushing surface 1112 is configured as an inclined surface relative to the first bottom surface 1111, or as an arc surface. The first pushing surface 1112 intersects the first bottom surface 1111 directly to form an edge line, which facilitates the insertion of the first extended portion 111 into the small gap between the locking piece 23 and the nut.

[0047] In some specific embodiments, reference is made to Figure 7 The angle between the second pushing surface 1122 and the second bottom surface 1121 is 90°, meaning the second pushing surface 1122 is perpendicular to the second bottom surface 1121. In other embodiments, the angle between the second pushing surface 1122 and the second bottom surface 1121 may also be greater than 90°, meaning the end of the second pushing surface 1122 away from the main body 113 extends further than the end of the second bottom surface 1121 away from the main body 113. In other embodiments, the angle between the second pushing surface 1122 and the second bottom surface 1121 may also be less than 90°, but greater than the angle between the first pushing surface 1112 and the first bottom surface 1111. In this case, the second pushing surface 1122 is set as an inclined surface relative to the second bottom surface 1121, or as an arc surface.

[0048] Based on the first embodiment, in some embodiments of the present invention, reference is made to Figure 5 , Figure 6 The locking tab unfolding device 100 also includes a first limiting component 150, which is aligned with the unfolding component 110 along the pushing direction of the unfolding component 110 (e.g., Figure 6 The fastening components are arranged sequentially from right to left, and the first limiting component 150 is configured to restrict the movement of the fastening component 20 along the pushing direction, thereby preventing the fastening component 20 from moving as a whole during the process of the unfolding component 110 pushing the locking piece 23. The unfolding component 110 can abut against the first fastener 21 to limit the fastening component 20, or it can abut against the second fastener 22 to limit the fastening component 20, or it can abut against both to limit the fastening component 20.

[0049] When the locking tab unfolding device 100 further includes a first limiting component 150, in some embodiments of the present invention, refer to Figure 5 , Figure 6The first limiting component 150 includes a first clamping component 151 and a second clamping component 152, which are capable of relative movement to switch between a first closed state and a first open state. Correspondingly, the locking tab unfolding device 100 also includes a sixth transmission component 160, which is connected to the first limiting component 150 and configured to be driven to move the first clamping component 151 and the second clamping component 152 relative to each other to switch states. Similarly, in some embodiments, the locking tab unfolding device 100 has its own power source, which drives the first clamping component 151 and the second clamping component 152 to move relative to each other to switch states via the sixth transmission component 160. In other embodiments, the locking tab unfolding device 100 does not have a power source, but relies on an external power source to drive the first clamping component 151 and the second clamping component 152 to move relative to each other to switch states via the sixth transmission component 160.

[0050] In this embodiment, the first limiting component 150 is configured to restrict the movement of the fastening component 20 in the pushing direction by the first clamping component 151 and / or the second clamping component 152. For example, the first clamping component 151 and the second clamping component 152 are configured as clamping seats. The side of the clamping seat facing the unfolding component 110 is used to abut against the first fastener 21. The first clamping component 151 can abut against the first fastener 21 to limit the movement, the second clamping component 152 can abut against the first fastener 21 to limit the movement, or both of them can abut against the first fastener 21 together to limit the movement.

[0051] As mentioned earlier, before replacing the conduit 30, it needs to be cut off. Therefore, a portion of the conduit 30 will remain on the nut. Based on this, the first limiting component 150 is also configured to clamp the conduit 30 connected to the first fastener 21 through the first clamping component 151 and the second clamping component 152 in the first closed state, thereby limiting the conduit 30 radially and preventing the fastening component 20 from moving and affecting the unfolding of the locking piece 23. For example, both the first clamping component 151 and the second clamping component 152 have clamping grooves on opposite sides, and the clamping grooves match the shape of the conduit 30.

[0052] In some specific embodiments, the sixth transmission assembly 160 includes a third transmission shaft 161, which can be driven to rotate and drive relative movement between the first clamping member 151 and the second clamping member 152. In the illustrated embodiment, the second clamping member 152 is stationary while the first clamping member 151 moves actively. For example, the third transmission shaft 161 is rotatably connected to the second clamping member 152 and threadedly connected to the first clamping member 151. As the third transmission shaft 161 rotates, the first clamping member 151 can move closer to or further away from the second clamping member 152.

[0053] Based on the first embodiment, in some embodiments of the present invention, the first transmission assembly 130 includes a first transmission shaft 131, which is driven to rotate and thus drive the unfolding assembly 110 to rotate. The first transmission shaft 131 is rotatably connected to the mounting base 136 of the first transmission assembly 130. The first transmission assembly 130 may also include a transmission gear set, which is connected to the unfolding assembly 110. When the first transmission shaft 131 receives power from a power source and rotates relative to the first base 120, it drives the transmission gear set to rotate, thereby driving the unfolding assembly 110 to rotate. Specifically, refer to... Figure 5 , Figure 6 The transmission gear set includes a first transmission gear 132 and a second transmission gear 133. The first transmission gear 132 and the second transmission gear 133 mesh with each other. The first transmission gear 132 can be driven by the first transmission shaft 131 to rotate synchronously. The second transmission gear 133 is fixedly connected to the unfolding component 110. This embodiment uses a transmission gear set for transmission, resulting in a compact structure.

[0054] Based on the first embodiment, in some embodiments of the present invention, the second transmission assembly 140 includes a second transmission shaft 141, which can be driven to rotate and move the unfolding assembly 110. The second transmission shaft 141 is rotatably connected to the first base 120. The second transmission assembly 140 also includes a third transmission gear 142 and a first rack 143. The third transmission gear 142 is fixedly connected to the second transmission shaft 141 and meshes with the first rack 143. The first rack 143 extends along the pushing direction of the unfolding assembly 110. Thus, as the second transmission shaft 141 rotates, the unfolding assembly 110 can move linearly.

[0055] Based on the first embodiment, in some embodiments of the present invention, when the locking plate unfolding device is not equipped with a power source, each transmission component is equipped with a drive end for receiving power. Taking the first transmission shaft 131 as an example, the top end of the first transmission shaft 131 extends from the first base 120 to form a drive end 1311. When the operator performs maintenance from above the reactor, after the locking plate unfolding device 100 moves downward from above the reactor, the operator uses an operating rod with an internal hexagonal hole to engage the drive end 1311 to drive the first transmission shaft 131 to rotate. Therefore, it is necessary to keep the drive end 1311 facing upward and extending from the first base 120. Based on this, the drive ends of the transmission shafts of the aforementioned transmission components all face upward, thereby facilitating the operator to drive each transmission shaft to rotate.

[0056] It should be noted that when the locking plate unfolding device is used for... Figure 5When the locking piece 23 of the fastening assembly 20 shown is unfolded, since the axis of the first transmission shaft 131 is perpendicular to the axis of the nut, the first transmission assembly 130 may further include, as shown in the figure. Figure 5 , Figure 6 The first bevel gear 134 and the second bevel gear 135 are shown. The first bevel gear 134 is fixedly connected to the first drive shaft 131, and the second bevel gear 135 meshes with both the first bevel gear 134 and the first drive gear 132, thereby changing the direction of force transmission. When the locking plate unfolding device is used to unfold the locking plate 23 of the fastening assembly 20 with its shaft in a vertical position, the first bevel gear 134 and the second bevel gear 135 can be omitted since the axis of the first drive shaft 131 is parallel to the axis of the nut.

[0057] In other embodiments, the locking tab unfolding device is provided with a power source, such as a motor, which can be connected to the first drive shaft 131 to drive the first drive shaft 131 to rotate.

[0058] The present invention also proposes a locking plate reset device 200 for resetting the locking plate 23 after reinstalling the first fastener 21 and the conduit 30, so as to perform subsequent welding operations. (See reference...) Figure 11 , Figure 12 The diagram shows a perspective view and a top view of the locking plate reset device 200 in an embodiment of the present invention. It includes a reset component 210, a second base 220 and a third transmission component 230. The second base 220 serves as the mounting body for mounting the aforementioned reset component 210, third transmission component 230 and other structures. The reset component 210 is used to reset the locking plate 23, and the third transmission component 230 is used to transmit power to drive the reset component 210.

[0059] Reference Figure 13 , Figure 14 The reset assembly 210 has a reset channel 213. The inner diameter of the reset channel 213 is larger than the outer diameter of the first fastener 21 and the second fastener 22, but smaller than the outer diameter of the locking piece 23 in the unfolded state. This allows the first fastener 21 and the second fastener 22 to pass through while also allowing them to abut against the locking piece 23. It should be noted that the "inner diameter" and "outer diameter" referred to here are not limited to circular shapes. Taking the locking piece 23 as an example, the outer diameter of the locking piece 23 in the unfolded state refers to the distance between the farthest end of the locking piece 23 and the axis of the washer 25.

[0060] The third transmission assembly 230 is connected to the reset assembly 210. The third transmission assembly 230 is configured to be driven to move the reset assembly 210 relative to the second base 220, so that the reset assembly 210 pushes the locking piece 23 to reset. Specifically, the third transmission assembly 230 can drive the reset assembly 210 to translate relative to the second base 220 along the axial direction of the nut to push it. That is, the reset assembly 210 and the fastening assembly 20 are distributed along the axial direction of the nut. Similarly, in some embodiments, the locking piece unfolding device 100 has its own power source, which drives the reset assembly 210 to move through the third transmission assembly 230 to push the locking piece 23. In other embodiments, the locking piece unfolding device 100 does not have a power source, but relies on an external power source to drive the reset assembly 210 to move through the third transmission assembly 230 to push the locking piece 23.

[0061] Based on the above structure, the locking plate reset device 200 of this embodiment is configured such that when the reset component 210 is sleeved on the second fastener 22, the reset component 210 can push the locking plate 23 to bend towards the first fastener 21, so that the locking plate 23 switches from the unfolded state to the connected state. In this way, the locking plate 23 can be reset for subsequent welding operations. Furthermore, power is transmitted through the third transmission component 230 to push the reset component 210, allowing operators to remotely control the locking plate reset device 200 to reset the locking plate 23, thus adapting to working environments such as reactors.

[0062] Based on the foregoing embodiments, in some embodiments of the present invention, reference is made to... Figure 14 The reset assembly 210 includes a third clamping member 211 and a fourth clamping member 212, which are capable of relative movement to switch between a second closed state and a second open state. Correspondingly, the locking plate reset device 200 also includes a fifth transmission assembly 250, which is connected to the reset assembly 210 and configured to be driven to move the third clamping member 211 and the fourth clamping member 212 relative to each other to switch states. Similarly, in some embodiments, the locking plate reset device 200 has its own power source, which drives the third clamping member 211 and the fourth clamping member 212 to move relative to each other to switch states via the fifth transmission assembly 250. In other embodiments, the locking plate reset device 200 does not have a power source, but relies on an external power source to drive the third clamping member 211 and the fourth clamping member 212 to move relative to each other to switch states via the fifth transmission assembly 250.

[0063] In some specific embodiments, the fifth transmission assembly 250 includes a fifth transmission shaft 251, which can be driven to rotate and drive relative movement between the third clamping member 211 and the fourth clamping member 212. In the illustrated embodiment, the fourth clamping member 212 is stationary while the third clamping member 211 moves actively. For example, the fifth transmission shaft 251 is rotatably connected to the fourth clamping member 212 and threadedly connected to the third clamping member 211. As the fifth transmission shaft 251 rotates, the third clamping member 211 can move closer to or further away from the fourth clamping member 212.

[0064] Based on the above structure, when the third clamping member 211 and the fourth clamping member 212 are in the second closed state (e.g.) Figure 14 In the state shown), the two define the reset channel 213, and the third clamping member 211 and the fourth clamping member 212 can be positioned along the direction from the second fastener 22 to the first fastener 21 (e.g., for...). Figure 12 Regarding the locking piece 23 on the left side, the third clamping member 211 and the fourth clamping member 212 push the locking piece 23 toward the first fastener 21 in a direction from right to left, so that the locking piece 23 switches from the unfolded state to the connected state.

[0065] When the third clamping member 211 and the fourth clamping member 212 are in the second open state, the second fastener 22 can enter the reset channel 213 radially. After the new conduit 30 and nut are replaced, the conduit 30 will extend a longer length from the nut. Based on this, this embodiment, by placing the third clamping member 211 and the fourth clamping member 212 in the second open state, facilitates the second fastener 22 to enter the reset channel 213 radially, eliminating obstruction of the conduit 30.

[0066] In other embodiments, reference is made to Figure 13 , Figure 14 The reset assembly 210 includes a third clamping component 211 and a fourth clamping component 212. The third clamping component 211 and the fourth clamping component 212 can move relative to each other to switch between a third closed state, a fourth closed state, and a third open state. The difference between this embodiment and the previous embodiment is that in the previous embodiment, the locking piece 23 can be switched from the unfolded state to the connected state by moving the third clamping component 211 and the fourth clamping component 212 along the axis of the nut. However, in this embodiment, after the third clamping component 211 and the fourth clamping component 212 move along the axis of the nut, the third clamping component 211 and the fourth clamping component 212 need to be further clamped in order to finally switch the locking piece 23 to the connected state.

[0067] Specifically, in this embodiment, when the third clamping member 211 and the fourth clamping member 212 are in the third closed state and the fourth closed state, both can define the reset channel 213. For ease of description, the reset channel 213 defined when the third clamping member 211 and the fourth clamping member 212 are in the third closed state is named the first reset channel (e.g., ...). Figure 13 As shown), the reset channel 213 defined when the third clamping member 211 and the fourth clamping member 212 are in the fourth closed state is named the second reset channel (e.g., Figure 14 As shown in the figure, the inner diameter of the first reset channel is larger than the inner diameter of the second reset channel.

[0068] Based on the above structure, when the third clamping component 211 and the fourth clamping component 212 are in the third closed state, the second fastener 22 is located in the first reset channel. The third clamping component 211 and the fourth clamping component 212 can push the locking piece 23 towards the first fastener 21 along the direction from the second fastener 22 to the first fastener 21. After the locking piece 23 is bent, the third clamping component 211 and the fourth clamping component 212 move relative to each other to the fourth closed state, so that the locking piece 23 switches to the connected state. Since this embodiment also provides a fourth closed state to further clamp the locking piece 23, the free end of the locking piece 23 can be closer to the first fastener than its fixed end (e.g., Figure 2 (as shown in the image), which facilitates subsequent welding.

[0069] When the third clamping component 211 and the fourth clamping component 212 are in the third open state, the second fastener 22 can enter the reset channel 213 radially along the reset channel 213, as can be understood by referring to the aforementioned embodiment.

[0070] In other embodiments, the reset assembly 210 may also be an overall ring structure, with a notch on the side of the ring structure for the second fastener 22 or the conduit 30 to enter.

[0071] Based on the second embodiment, in some embodiments of the present invention, reference is made to Figure 11 The third transmission assembly 230 includes a fourth transmission shaft 231, which can be driven to rotate and move the reset assembly 210. The fourth transmission shaft 231 is rotatably connected to the second base 220. The third transmission assembly 230 also includes a fourth transmission gear 232 and a second rack 233. The fourth transmission gear 232 is fixedly connected to the fourth transmission shaft 231 and meshes with the second rack 233. The second rack 233 extends along the pushing direction of the reset assembly 210. Thus, as the fourth transmission shaft 231 rotates, the reset assembly 210 can move linearly.

[0072] Based on the foregoing embodiments, in some embodiments of the present invention, reference is made to... Figure 11 , Figure 12 The locking tab unfolding device 100 also includes a second limiting component 240, which is aligned with the reset component 210 along the pushing direction of the reset component 210 (e.g., Figure 12 The components are arranged sequentially from right to left, and the second limiting component 240 is configured to restrict the movement of the fastening component 20 along the pushing direction, thereby preventing the fastening component 20 from moving as a whole during the process of the reset component 210 pushing the locking piece 23. The reset component 210 can abut against the first fastener 21 to limit the fastening component 20, or it can abut against the second fastener 22 to limit the fastening component 20, or it can abut against both to limit the fastening component 20.

[0073] When the locking tab unfolding device 100 further includes a second limiting component 240, in some embodiments of the present invention, refer to Figure 11 The second limiting component 240 has a receiving groove 241. The second limiting component 240 is configured to abut against the first fastener 21 to limit the movement of the fastening component 20 in the pushing direction, and to accommodate the conduit 30 connected to the first fastener 21 through the receiving groove 241. As mentioned above, before the conduit 30 needs to be replaced, it needs to be cut off, so a part of the conduit 30 will remain on the nut. In this embodiment, the receiving groove 241 accommodates the conduit 30, which can both support the conduit 30 and limit its radial movement. For example, the second limiting component 240 includes a support seat. The side of the support seat facing the reset component 210 is used to abut against the first fastener 21. The upper side of the support seat is provided with a receiving groove 241, which matches the shape of the conduit 30.

[0074] Similarly, in some embodiments of the present invention, when the locking plate unfolding device is not equipped with a power source, each transmission component is provided with a drive end for receiving power. Taking the fourth transmission shaft 231 as an example, the top end of the fourth transmission shaft 231 extends from the second base 220 to form a drive end. When the operator performs maintenance from above the reactor, after the locking plate unfolding device 100 moves downward from above the reactor, the operator uses an operating rod with an internal hexagonal hole to engage the drive end to drive the fourth transmission shaft 231 to rotate. Therefore, it is necessary to keep the drive end facing upward and extending from the second base 220. Based on this, the drive ends of the fourth transmission shaft 231 and the fifth transmission shaft 251 are both facing upward, which facilitates the operator to drive each transmission shaft to rotate.

[0075] The present invention also proposes a processing device, with reference to Figure 15 , Figure 16The diagrams show perspective views of the processing device 10 in different scenarios according to the second embodiment of the present invention. The processing device 10 includes a mounting platform 300, which is used to connect to external components. For example, the mounting platform 300 can be connected to a support inside the reactor, specifically near the fastening assembly 20 of the locking plate to be deployed or reset. The mounting platform 300 can be connected by, for example, threaded fasteners.

[0076] The processing device also includes the locking plate unfolding device 100 and the locking plate resetting device 200 in the aforementioned embodiments and related embodiments. Both the locking plate unfolding device 100 and the locking plate resetting device 200 can be detachably connected to the mounting platform 300. During use, the locking plate unfolding device 100 and the locking plate resetting device 200 can be selectively connected to the mounting platform 300. That is, when it is necessary to unfold the locking plate 23, the locking plate unfolding device 100 is connected to the mounting platform 300 and the locking plate resetting device 200 is separated from the mounting platform 300. When it is necessary to reset the locking plate 23, the locking plate resetting device 200 is connected to the mounting platform 300 and the locking plate unfolding device 100 is separated from the mounting platform 300. The locking plate unfolding device 100 and the locking plate resetting device 200 can be detachably connected to the mounting platform 300 via threaded fasteners. To achieve this effect, the locking plate unfolding device 100 and the locking plate resetting device 200 are provided with the same mounting position for connection with the same mounting position on the mounting platform 300.

[0077] Based on the second embodiment, in some embodiments of the present invention, reference is made to Figure 15 , Figure 16 The processing device 10 also includes a fourth transmission assembly 400, which is connected to the mounting platform 300. The locking plate unfolding device 100 and the locking plate resetting device 200 are selectively connected to the fourth transmission assembly 400. That is, the locking plate unfolding device 100 and the locking plate resetting device 200 are selectively connected to the mounting platform 300 through the fourth transmission assembly 400.

[0078] In this embodiment, the fourth transmission component 400 is configured to be driven to move the locking plate unfolding device 100 or the locking plate resetting device 200 relative to the mounting platform 300, so that the locking plate unfolding device 100 or the locking plate resetting device 200 moves to a processing position suitable for processing the locking plate 23. The processing of the locking plate 23 referred to here means unfolding or resetting the locking plate 23. For the unfolding operation, it specifically refers to the position of the first unfolding part 111 facing the gap between the locking plate 23 and the nut. For the resetting operation, it refers to the position of the pipe connector body located in the resetting channel 213. Since this invention needs to be applied to the remote unfolding and resetting of the locking plate 23, it is difficult to directly move the unfolding component 110 or the resetting component 210 to the processing position. In this embodiment, by setting the fourth transmission component 400, the entire processing device 10 can be fixed to the attachment of the fastening component 20 to be processed by the mounting platform 300. Then, the fourth transmission component 400 drives the locking plate unfolding device 100 or the locking plate resetting device 200 to move for precise adjustment, so that the unfolding component 110 or the resetting component 210 moves to the processing position.

[0079] The fourth transmission assembly 400 can drive the locking plate unfolding device 100 or the locking plate resetting device 200 to move along at least one of the X-axis, Y-axis, and Z-axis directions. In some specific embodiments, the fourth transmission assembly 400 can drive the locking plate unfolding device 100 or the locking plate resetting device 200 to move along the aforementioned three directions, so that the locking plate unfolding device 100 or the locking plate resetting device 200 can change its position in space. For example, the fourth transmission assembly 400 includes at least one transmission shaft arranged corresponding to the moving direction of the locking plate unfolding device 100 or the locking plate resetting device 200. As the transmission shaft rotates, the locking plate unfolding device 100 or the locking plate resetting device 200 can move in the corresponding direction. The transmission method in each direction of the fourth transmission assembly 400 can be understood with reference to the aforementioned fifth transmission assembly 250 or third transmission assembly 230.

[0080] Similarly, in some embodiments, the processing device 10 has its own power source, which drives the locking plate unfolding device 100 or the locking plate resetting device 200 to move through the fourth transmission component 400. In other embodiments, the locking plate unfolding device 100 is not provided with a power source, but relies on an external power source to drive the locking plate unfolding device 100 or the locking plate resetting device 200 to move through the fourth transmission component 400.

[0081] In addition, when the locking plate unfolding device is not equipped with a power source, each drive shaft of the fourth transmission assembly 400 is provided with a drive end for receiving power. Each drive shaft extends from the fourth transmission assembly 400 to form a drive end, and the drive ends all face upwards, so as to facilitate the operator to drive each drive shaft to rotate.

[0082] Based on the second embodiment, in some embodiments of the present invention, the processing device 10 further includes a camera, which is used to acquire first image information including the locking plate unfolding device 100 and the fastening component 20. The locking plate unfolding device 100 can move to the processing position based on the first image information, thereby realizing the precise docking of the locking plate unfolding device 100 and the locking plate 23.

[0083] Based on the second embodiment, in some embodiments of the present invention, the processing device 10 further includes a camera, which is used to acquire second image information including the locking plate reset device 200 and the fastening component 20. The locking plate reset device 200 can move to the processing position based on the second image information, thereby realizing the precise docking of the locking plate reset device 200 and the locking plate 23.

[0084] Based on the second embodiment, in some embodiments of the present invention, the processing device 10 further includes a camera for acquiring third image information containing the fastening component 20 that has been deployed, thereby determining whether the locking piece 23 has been successfully deployed.

[0085] Based on the second embodiment, in some embodiments of the present invention, the processing device 10 further includes a camera for acquiring fourth image information containing the fastening component 20 that has undergone a reset operation, thereby determining whether the locking piece 23 has been successfully reset.

[0086] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
