Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] The following is for reference. Figures 1-6 The loading and unloading fixture 100 according to an embodiment of the present invention can be used in a tokamak nuclear reactor, or in other environments with limited working space and no electrical conditions, or for disassembling some heavy components, or in some environments with radiation.

[0022] like Figures 1-6 As shown, according to an embodiment of the present invention, a loading and unloading fixture 100 includes: a support 10, a clamping assembly 20, and a manual drive assembly 30. The support 10 has a mounting portion 11 for connecting with an external structural member 200. The clamping assembly 20 is disposed on the support 10 and is used to cooperate with the part 300 to be loaded or unloaded. The manual drive assembly 30 is disposed on the support 10 and cooperates with the clamping assembly 20 for driving the clamping assembly 20 to move, thereby moving the part 300 to be loaded or unloaded.

[0023] The external structural component 200 can be some components on the tokamak nuclear reactor, and the component to be loaded and unloaded 300 can be other components inside the tokamak nuclear reactor. The support 10, by setting the mounting part 11, allows the entire loading and unloading fixture 100 to be directly installed on the external structural component 200, thereby fixing the loading and unloading fixture 100. After the mounting part 11 is properly engaged with the external structural component 200, it can also position the clamping assembly 20, facilitating the engagement of the clamping assembly 20 with the component to be loaded and unloaded 300.

[0024] The clamping assembly 20 is mounted on the support 10. The clamping assembly 20 is engaged with the manual drive assembly 30, so that the clamping assembly 20 can be moved manually, thereby driving the part to be installed or removed 300 to be installed or removed. The manual drive assembly 30 is driven by the operator and does not require electricity. That is, the entire tooling is a purely manual device with few parts and a simple structure, which can reduce the space occupied.

[0025] According to the embodiment of the present invention, the loading and unloading fixture 100 is designed with an installation part 11 so that the entire fixture can be directly installed on the external structural component 200. By designing a manual drive component 30 to drive the clamping component 20, the loading and unloading of the component 300 to be loaded and unloaded can be achieved manually. This can overcome the limitations of factors such as site power supply. Moreover, the overall structure is simple and easy to use, which can reduce the difficulty of loading and unloading the component 300 to be loaded and unloaded.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, the clamping assembly 20 includes a connector 21 and multiple clamping heads 22. The connector 21 is disposed on the support 10 and is connected to the manual drive assembly 30. The multiple clamping heads 22 are connected to the connector 21 and can be inserted into the component 300 to be loaded or unloaded. The manual drive assembly 30 drives the connector 21 to move, thereby causing the multiple clamping heads 22 to cooperate with the component 300 to be loaded or unloaded. The component 300 to be loaded or unloaded can be clamped and engaged with the clamping heads 22 under the action of gravity. That is to say, the clamping heads 22 can grip the component 300 to be loaded or unloaded by relying on the gravity of the component 300 itself, thereby achieving the cooperation between the clamping heads 22 and the component 300 to be loaded or unloaded. Thus, when the manual drive assembly 30 drives the clamping assembly 20 to move, it drives the component 300 to move, thereby realizing the installation or removal of the component 300 to be loaded or unloaded.

[0027] Of course, the clamping head 22 may also be provided with a snap-fit ​​part, so that the part to be loaded or unloaded 300 can be snapped into the clamping head 22, and then when the manual drive component 30 drives the clamping component 20 to move, the part to be loaded or unloaded 300 can be moved to realize the installation or removal of the part to be loaded or unloaded 300.

[0028] like Figure 2As shown, in some specific embodiments, the clamping head 22 includes at least one first clamping head 221 and at least one second clamping head 222. In the vertical direction, the second clamping head 222 is located below the first clamping head 221. The first clamping head 221 can abut against the component 300 to be loaded or unloaded, so that the component 300 to be loaded or unloaded is supported on the first clamping head 221. That is, the component 300 to be loaded or unloaded can act on the first clamping head 221 by gravity. Thus, the movement of the clamping assembly 20 can drive the component 300 to be loaded or unloaded to move, thereby removing or installing the component 300 to be loaded or unloaded.

[0029] Furthermore, since the component to be loaded or unloaded 300 usually has a certain weight, when the first clamping head 221 drags the component to be loaded or unloaded 300 to move, the component to be loaded or unloaded 300 tends to tilt to the side. When the component to be loaded or unloaded 300 tilts to the side, the second clamping head 222 can abut against the component to be loaded or unloaded 300, thereby clamping the component to be loaded or unloaded 300 with the clamping head 22. That is to say, the component to be loaded or unloaded 300 can act on the first clamping head 221 through gravity, and at the same time, under the action of gravity, the component to be loaded or unloaded 300 can also abut against the second clamping head 222, thereby realizing the clamping engagement between the clamping head 22 and the component to be loaded or unloaded 300. This can reduce the probability of the component to be loaded or unloaded 300 disengaging from the clamping assembly 20, prevent the component to be loaded or unloaded 300 from falling, and thus facilitate the removal or installation of the component to be loaded or unloaded 300.

[0030] like Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the upper surface of the first clamping head 221 is provided with a first limiting step 2211. The first limiting step 2211 is located at the end of the first clamping head 221. The first limiting step 2211 can be formed by a downward indentation of a portion of the upper surface of the first clamping head 221. Thus, the first limiting step 2211 has two supporting surfaces. When the clamping assembly 20 extends into the component 300 to be loaded or unloaded, the first clamping head 221 extends into the first mating hole 310. The supporting surface with a higher relative position to the first limiting step 2211 can first contact the component 300 to be loaded or unloaded, and at the same time play a certain guiding role in the movement of the entire clamping assembly 20. When the first clamping head 221 extends into place, both supporting surfaces of the first limiting step 2211 can contact the component 300 to be loaded or unloaded. Figure 5 and Figure 6 As shown, some components 300 to be loaded or unloaded are assembled from multiple sub-parts. Each sub-part has staggered through holes. The first limiting step 2211 can cooperate with the multiple sub-parts to improve the support effect of the components 300 to be loaded or unloaded. At the same time, under the design of the first limiting step 2211, the contact surface between the first clamping head 221 and the components 300 to be loaded or unloaded is increased, improving the stability of the cooperation.

[0031] like Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the lower surface of the second clamping head 222 has a second limiting step 2221. The second limiting step 2221 is located at the end of the second clamping head 222. The second limiting step 2221 can be formed by a portion of the lower surface of the second clamping head 222 being recessed upwards. Thus, the second limiting step 2221 also forms two limiting surfaces. When the clamping assembly 20 extends into the component 300 to be loaded or unloaded, the second clamping head 222 extends into the second mating hole 320. The design of the second limiting step 2221 can avoid the probability of interference between the second clamping head 222 and the component 300 to be loaded or unloaded, facilitating the further extension of the entire clamping assembly 20. When the first clamping head 221 mates with the component 300 to be loaded or unloaded... After positioning, the first clamping head 221 is extended backward by the manual drive component 30, causing the component to be loaded / unloaded 300 to move backward. When the component to be loaded / unloaded 300 moves, it tends to rotate counterclockwise. At this time, the wall of the second mating hole 320 can abut against the second clamping head 222, and the two limiting surfaces of the second limiting step 2221 can abut against the two sub-parts of the component to be loaded / unloaded 300 respectively. This allows the clamping head 22 to be locked with multiple parts of the component to be loaded / unloaded 300, thereby improving the clamping effect of the clamping component 20, reducing the probability of the component to be loaded / unloaded 300 disengaging from the clamping component 20, preventing the component to be loaded / unloaded 300 from falling, and facilitating the removal or installation of the component to be loaded / unloaded 300.

[0032] In other words, the end of each clamping head 22 is specially designed according to the characteristics of the component 300 to be loaded or unloaded, so that the component 300 to be loaded or unloaded can be gripped by gravity, thereby improving the reliability of the loading and unloading process.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, the connector 21 is a plate-shaped structure, and the first clamping head 221 and the second clamping head 222 extend in a direction perpendicular to the connector 21. Thus, the connector 21 does not occupy too much space, and when the manual drive component 30 drives the clamping component 20 to move, the first clamping head 221 and the second clamping head 222 extend into the component to be loaded or unloaded 300, the connector 21 can also make a certain contact with the component to be loaded or unloaded 300, thereby improving the stability of the component to be loaded or unloaded 300, reducing the probability of the component to be loaded or unloaded 300 disengaging from the clamping component 20, and facilitating the removal or installation of the component to be loaded or unloaded 300.

[0034] like Figure 2As shown, in some embodiments, the first clamping head 221 includes a plurality of spaced-apart clamping heads. By providing a plurality of first clamping heads 221, the supporting effect of the first clamping heads 221 on the component 300 to be loaded or unloaded is improved, and the stability of the component 300 to be loaded or unloaded is improved. The second clamping head 222 includes a plurality of spaced-apart clamping heads. By providing a plurality of second clamping heads 222, the contact surface between the second clamping head 222 and the component 300 to be loaded or unloaded can be increased when the component 300 to be loaded or unloaded is tilted to the side, thereby improving the clamping effect on the component 300 to be loaded or unloaded and reducing the probability of the component 300 to be loaded or unloaded disengaging from the clamping assembly 20.

[0035] like Figures 1-3 As shown, in some embodiments, the manual drive assembly 30 includes a first drive assembly 31 and a second drive assembly 32. The first drive assembly 31 is disposed on the support 10, and the second drive assembly 32 is disposed on the first drive assembly 31. The clamping assembly 20 cooperates with the second drive assembly 32. The first drive assembly 31 is used to drive the clamping assembly 20 along a first direction (e.g., ...). Figure 1 The second drive assembly 32 is used to drive the clamping assembly 20 to move along the second direction (as shown in the front-back direction). Figure 1 The clamping component 20 can be moved in the up and down direction shown. The first direction and the second direction intersect. By setting two drive components, the position of the clamping component 20 in the two directions can be adjusted, which makes it easier for the clamping component 20 to cooperate with the part to be loaded or unloaded 300. Furthermore, by designing the manual drive component 30 as two drive components, the structure of each drive component can be simplified, making it easier for operators to operate.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments, the support 10 defines a guide groove 121. The first drive assembly 31 includes a first lead screw 311, a first moving member 312, and a first operating member 313. The first lead screw 311 is rotatably disposed in the guide groove 121. The first operating member 313 is connected to the first lead screw 311 and is used to drive the first lead screw 311 to rotate. The first operating member 313 can be a hand crank. The first operating member 313 can be connected to one end of the first lead screw 311, for example, by welding or fasteners. The first moving member 312 is threadedly engaged with the first lead screw 311. The second drive assembly 32 is connected to the first moving member 312. The clamping assembly 20 is connected to the second drive assembly 32. At least a portion of the first moving member 312 is disposed in the guide groove 121, and the first moving member 312 is slidably engaged with the guide groove 121, thereby improving the stability of the clamping assembly 20 when moving along the first direction.

[0037] In the above embodiments, the first drive component 31 adopts a lead screw and slider method, which has a simple overall structure and high positioning accuracy. It ensures the accuracy of the movement position of the clamping component 20 and converts the rotational torque into axial thrust, reducing the space occupied by the arrangement and operation. At the same time, the force is multiplied by reducing the pitch, thereby achieving the effect of saving effort when handling the parts to be loaded and unloaded 300, which is convenient for operators to use.

[0038] Of course, the first drive component 31 can also be driven by a gear and rack assembly or other means.

[0039] like Figure 3 As shown, in some embodiments, the second drive assembly 32 includes a second lead screw 321, a second moving member 322, and a second operating member 323. The second lead screw 321 is rotatably mounted on the first moving member 312, and the first moving member 312 can be connected to one end of the second lead screw 321, for example, by welding or fastener connection.

[0040] The second operating element 323 is connected to the second lead screw 321. The second operating element 323 is used to drive the second lead screw 321 to rotate. The second operating element 323 can be a hand crank. The second operating element 323 can be connected to one end of the second lead screw 321, for example, by welding or fasteners.

[0041] The second moving part 322 is threadedly engaged with the second lead screw 321, and the clamping assembly 20 is connected to the second moving part 322. For example, the connecting part 21 is connected to the second moving part 322 by a fastener. Thus, by rotating the second operating part 323, the second moving part 322 moves, which in turn moves the clamping assembly 20. This process can be carried out after a part of the clamping assembly 20 extends into the part to be loaded or unloaded 300. Thus, the part to be loaded or unloaded 300 limits the movement direction of the second moving part 322 and the clamping assembly 20, preventing the second moving part 322 from rotating with the second lead screw 321.

[0042] In the above embodiments, the second drive component 32 adopts a lead screw and slider method, which has a simple overall structure and high positioning accuracy, ensuring the accuracy of the movement position of the clamping component 20. At the same time, it converts the rotational torque into axial thrust, reducing the space occupied by the arrangement and operation, and making it convenient for operators to use and operate in a confined space.

[0043] Of course, the second drive component 32 can also be driven by a gear and rack assembly or other similar methods.

[0044] like Figures 1-4As shown, in some embodiments, the loading and unloading fixture 100 further includes a balancing component 40. The clamping component 20 is disposed on one side of the second moving member 322, the balancing component 40 is disposed on the support 10, and the balancing component 40 is located on the other side of the second moving member 322. By setting the balancing component 40, the gravity of the component to be loaded or unloaded 300 supported on the clamping component 20 can be balanced, thereby improving the stability of the entire fixture.

[0045] like Figure 3 As shown, in some examples, the balancing assembly 40 includes a slider 41 and at least one connecting rod 42. At least a portion of the slider 41 is disposed in the guide groove 121, and the slider 41 is slidably engaged with the first lead screw 311, or the slider 41 is slidably engaged with the guide groove 121, or the slider 41 is simultaneously slidably engaged with both the first lead screw 311 and the guide groove 121. One end of the connecting rod 42 is rotatably connected to the slider 41, and the other end of the connecting rod 42 is rotatably connected to the second moving member 322. This avoids interference between the design of the balancing assembly 40 and the movement of the second moving member 322. At the same time, under the limitation of the balancing assembly 40, the second moving member 322 can only move in the second direction and will not rotate, thus improving the reliability of the overall structure.

[0046] The connecting rod 42 extends in a direction inclined to the first and second directions. The connecting rod 42 can be used to balance the parts to be loaded and unloaded 300, thereby improving the stability of the entire tooling.

[0047] like Figures 1-3 As shown, in some embodiments, the support 10 includes a support body 12 and a mounting portion 11. The support body 12 extends along a first direction and defines a guide groove 121. The mounting portion 11 is located at one end of the support body 12 and has a mounting hole 112. The mounting portion 11 is connected to the external structural member 200 by a fastener passing through the mounting hole 112, thereby improving the reliability of the connection.

[0048] The mounting part 11 has a mounting groove 111, which is used to fit against the outer surface of the external structural component 200. By designing the mounting groove 111, the support 10 fits better against the external structural component 200 during installation, improving the reliability of the fit between the two, improving the stability of the support 10, and thus improving the reliability of the loading and unloading tooling 100 during use.

[0049] In some specific examples, the external structural component 200 has a connection hole through which the external structural component 200 can be connected to other components. When it is necessary to use the loading and unloading fixture 100 for disassembly, the external structural component 200 is disassembled from other components. Using the connection hole on the external structural component 200, fasteners are passed through the connection hole and the mounting hole 112 to install the loading and unloading fixture 100 on the external structural component 200 as a whole, thereby fixing the loading and unloading fixture 100.

[0050] The component to be loaded / unloaded 300 can be located inside the external structural component 200. The component to be loaded / unloaded 300 can be connected to the external structural component 200 by fasteners. When it is necessary to disassemble the component to be loaded / unloaded 300, the loading / unloading fixture 100 is first installed on the external structural component 200. The mounting groove 111 fits against the outer surface of the external structural component 200 and is fixedly connected to the connection hole of the external structural component 200 through the mounting hole 112. Then, by manually cranking the first operating component 313, the first lead screw 311 rotates, driving the first moving component 312 to move along the first direction. The second driving assembly 32 and the clamping assembly 20 also move along the first direction. Until the clamping head 22 approaches the component 300 to be loaded or unloaded, the second operating member 323 is manually cranked, the second lead screw 321 rotates, driving the second moving member 322 to move along the second direction, and the clamping assembly 20 moves along the second direction to adjust the position of the clamping head 22. Finally, the first operating member 313 is manually cranked to insert the clamping head 22 into the component 300 to be loaded or unloaded. At this time, the fasteners between the component 300 to be loaded or unloaded and the external structural member 200 are removed. Under the action of gravity, the component 300 to be loaded or unloaded is clamped onto the clamping head 22. Then, the first operating member 313 is manually cranked in the opposite direction to move the clamping assembly 20 and remove the component 300 to be loaded or unloaded.

[0051] Of course, the component to be loaded or unloaded 300 can also be located on one side of the external structural component 200, which mainly plays the role of positioning and fixing the loading and unloading fixture 100.
