Description

Technical Field

[0001] The invention relates to the technical field of neutron targets, and in particular to a disassembly and assembly mechanism for disassembling and assembling a rotating target piece assembly and a target changing method. Background Art

[0002] The target system is the core component of the ultra-high-intensity deuterium-tritium fusion neutron source. Its main function is to withstand the bombardment of high-power deuterium ion beams and produce neutrons through deuterium-tritium fusion reactions. Currently, the target system tends to use a rotating target. The rotation of the target can reduce the temperature of the target and avoid continuous heating.

[0003] Well, currently, when replacing the target piece of the rotating target, the target system as a whole is often replaced. When replacing, the entire target system needs to be replaced, which is difficult and relatively inefficient.

[0004] Moreover, although the prior art discloses a replacement system or device for the target system, it is difficult to apply it to the replacement of the target piece of the rotating target, because in actual application, the weight of the entire target system is relatively large. In order to ensure sufficient clamping force, the replacement structure is often a rigid clamping structure. Since the target piece of the rotating target is often disc-shaped or annular, compared with other flat target pieces, the target piece structure is thinner and the internal structure is more delicate. Especially for disc-shaped target pieces with a larger target piece area, if the rigid clamping structure is directly used to clamp the target piece, whether it is the thickness direction of the clamped target piece or the radial direction of the clamped target piece, it is easy to cause structural damage to the target piece, and then breakage or fragments will fall, which may make the entire environment full of radioactive substances. When the operator is required to repair and maintain the entire device, it will cause radioactive hazards to the operator.

[0005] In addition, the rotating target piece is generally connected to the rotating shaft together with the connecting structure to form a rotating target piece assembly installed on the rotating shaft. However, the existing replacement system or device has an overly large clamping part and an unbalanced clamping, which can easily cause the rotating target piece assembly to have position deviation during installation, resulting in difficulty or difficulty in installation.

[0006] Therefore, it is necessary to develop a disassembly, assembly and replacement mechanism for the rotating target piece assembly to achieve smooth replacement of the rotating target piece assembly. Summary of the invention

[0007] The purpose of the present invention is to provide a disassembly and assembly mechanism and a target changing method for disassembling and assembling a rotating target piece assembly, so as to solve the technical problem that the rotating target piece is prone to position deviation during the installation process, and also solve the technical problem that the rotating target piece is prone to falling during the disassembly and assembly process.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] On the one hand, a disassembly and assembly mechanism for disassembling and assembling a rotating target piece assembly is provided, wherein the rotating target piece assembly is used to be installed on a rotating shaft;

[0010] The disassembly and assembly mechanism is provided with a central axis corresponding to the rotating axis, and the central axis has the same cross-sectional diameter as the rotating axis. When disassembling and assembling the rotating target sheet assembly, the end of the central axis can abut against the opposite end of the rotating axis, and the center line of the central axis coincides with the center line of the rotating axis.

[0011] The disassembly and assembly mechanism is provided with a transfer assembly, and the transfer assembly can be adsorbed and connected with the rotating target sheet assembly. When the end of the central axis abuts against the end opposite to the rotating axis, the transfer assembly can drive the rotating target sheet assembly to move on the central axis and the rotating axis.

[0012] In this solution, when disassembling and assembling the target piece, the end of the central axis abuts against the end opposite to the rotating axis, and the center line of the central axis coincides with the center line of the rotating axis. Then, the principle of concentric axes is utilized to realize the "axis-to-axis" disassembly and assembly of the rotating target piece assembly, and it is moved to the central axis or the rotating axis accordingly. At the structural level, it can improve the accuracy of the target piece installation position, improve the disassembly and assembly efficiency, solve the technical problem that the rotating target piece assembly is prone to position deviation during the installation process, and also solve the technical problem that the rotating target piece assembly is prone to falling during the disassembly and assembly process.

[0013] As one of the implementation methods in which the transfer assembly can be adsorbed and connected to the rotating target sheet assembly, the transfer assembly includes a plurality of evenly distributed suction cup assemblies, each of which can be extended and retracted in a direction parallel to the extension direction of the central axis; the suction cup assembly includes a flexible suction cup, which is used to be adsorbed on the surface of the rotating target sheet assembly.

[0014] During the target replacement process, multiple suction cups are used to load or move the target piece, which solves the technical problem of structural damage that may be caused by the clamping method used in the prior art due to the thin and fragile structure of the annular target piece.

[0015] When the rotating target sheet assembly needs to be moved, each suction cup assembly is first extended so that each flexible suction cup is adsorbed on the surface of the rotating target sheet assembly, and then when the transport assembly moves, the rotating target sheet assembly can be driven to move.

[0016] As a preferred solution of the suction cup assembly, each of the suction cup assemblies is a vacuum suction cup device, each of the flexible suction cups is connected to one end of a vacuum tube, and the other end of each of the vacuum tubes is connected to a vacuum pumping device.

[0017] When the rotating target assembly needs to be moved, first extend each suction cup assembly and ensure that each suction cup is in contact with the rotating target assembly. Turn on the vacuum device to create a vacuum state between the inside of the flexible suction cup and the part in contact with the rotating target assembly, thereby achieving adsorption of the rotating target assembly.

[0018] As one of the implementation methods for achieving the extension and retraction of each suction cup assembly, a telescopic rod is provided at one end of the flexible suction cup away from the rotating target piece assembly, and the telescopic rod can drive the flexible suction cup to extend and retract in a direction parallel to the extension direction of the central axis.

[0019] As another way to realize the extension and retraction of each suction cup assembly, the disassembly and assembly mechanism is installed on the supporting structure through an installation bracket, a first bracket plate and a second bracket plate are fixed on the installation bracket, each suction cup assembly is installed on the first bracket plate, a plurality of screw rods are fixed between the first bracket plate and the second bracket plate corresponding to each suction cup assembly, a screw rod slider is respectively provided at one end of each suction cup assembly extending out of the first bracket plate, each screw rod slider is respectively threadedly connected with a corresponding screw rod, and a screw motor is fixed at one end of each screw rod extending out of the second bracket plate, each screw motor can rotate forward or reverse at the same time, and can drive each screw rod slider to move on the corresponding screw rod.

[0020] During forward rotation, the screw slider can move along the corresponding screw in a direction away from the screw motor to extend the suction cup assembly. During reverse rotation, the screw slider can move along the corresponding screw in a direction close to the screw motor to retract the suction cup assembly.

[0021] Preferably, the rotating target piece assembly includes a rotating target piece, the rotating target piece is used to be installed on the rotating shaft through a pressure cover, and the pressure cover is used to be sleeved on the rotating shaft; a plurality of bolt holes are arranged on the pressure cover, and the corresponding positions of the rotating target piece corresponding to each bolt hole are respectively provided with through holes; bolts are installed in each of the bolt holes and the corresponding through holes to achieve a fixed connection between the rotating target piece and the pressure cover; a rotating turntable is installed on the mounting bracket, and the rotating turntable has a fixed end and a rotating end, the fixed end is fixedly connected to the mounting bracket, and the end of the central axis away from the rotating shaft is fixedly connected to the center of the end face of the fixed end, and the rotating The end sleeve is arranged on the outer periphery of the central axis and is concentrically arranged with the central axis, and the rotating end can rotate relative to the central axis; a third bracket disk is fixed to the end surface of the rotating end away from the fixed end, and a fourth bracket disk is fixed to the third bracket disk through a support rod, and multiple drive motors are installed on the third bracket disk, and multiple wrenches are rotatably connected to the fourth bracket disk; the tail end of each wrench extends from the fourth bracket disk toward the third bracket disk, and is fixedly connected to the output end of each drive motor respectively, and each drive motor can rotate forward or reverse respectively and simultaneously, thereby driving each wrench to rotate forward or reverse, and each wrench is used to tighten or loosen multiple bolts at the same time.

[0022] In specific implementation, multiple bolts are often used to fix the rotating target piece, and the multiple bolts all pass through the rotating target piece, which can make the rotating target piece more secure when rotating. Then, for the rotating target piece fixed with multiple bolts, the pressure cover is provided with multiple bolt holes, and the positions corresponding to the bolt holes on the corresponding rotating target piece are respectively provided with through holes; bolts are installed in each of the bolt holes and the corresponding through holes to achieve a fixed connection between the rotating target piece and the pressure cover;

[0023] Each bolt corresponds to a position of each wrench, and each wrench can be clamped with the corresponding bolt, and each wrench can be rotated forward or reversed respectively and simultaneously, so as to tighten or loosen the corresponding bolt respectively.

[0024] When disassembling the rotating target piece, first dock the central shaft with the rotating shaft, then engage each wrench with each bolt and reverse at the same time, loosen each bolt, and then use the transfer assembly to transfer the pressure cover and the target piece from the rotating shaft to the central shaft to realize the disassembly of the rotating target piece.

[0025] When installing the rotating target piece, first put the new pressure cover and the target piece together on the central shaft, then dock the central shaft with the rotating shaft, and then use the transfer assembly to transfer the pressure cover and the target piece from the central shaft to the rotating shaft, and then make each wrench engage with each bolt and rotate forward at the same time, tighten each bolt to achieve the installation of the rotating target piece.

[0026] On the other hand, a target replacement method is provided, using the disassembly and assembly mechanism for disassembling and assembling the rotating target piece assembly as described above, comprising the following steps:

[0027] S1, firstly move the disassembly and assembly mechanism to a position close to the old rotating target assembly, and abut the central axis against the rotating axis, and ensure that the center line of the central axis coincides with the center line of the rotating axis;

[0028] S2. When disassembling the old rotating target sheet assembly, start each screw motor, make each screw motor rotate forward simultaneously and separately, make each suction cup assembly extend and fit with the surface of the old rotating target sheet assembly; then start each vacuum pumping device, make the part where each suction cup assembly fits with the old rotating target sheet assembly in a vacuum state, so as to achieve the adsorption of the old rotating target sheet assembly; then start each screw motor, make each screw motor reverse simultaneously and separately, make each suction cup assembly shrink, and move the old rotating target sheet assembly to the central axis; then close each vacuum pumping device, make each suction cup assembly release the old rotating target sheet assembly, remove the disassembly mechanism, separate the central axis from the rotating axis, remove the old rotating target sheet assembly, and complete the disassembly process;

[0029] S3. When installing a new rotating target piece assembly, place the new rotating target piece assembly on the central axis, and move the disassembly and assembly mechanism again to a position close to the installation target, and abut the central axis against the rotating axis, and ensure that the center line of the central axis coincides with the center line of the rotating axis; then start each screw motor, so that each screw motor rotates forward simultaneously and separately, so that each suction cup assembly extends, and pushes the new rotating target piece assembly to the target position to complete the installation of the new rotating target piece assembly.

[0030] In the present scheme, efficient disassembly and assembly can be achieved by utilizing the cooperation between various components. In addition, when disassembling and assembling the target piece, the end of the central axis abuts against the end opposite to the rotating axis, and the center line of the central axis coincides with the center line of the rotating axis. The rotating target piece assembly is disassembled and assembled in an "axis-to-axis" manner, which can improve the accuracy of the target piece installation position, solve the technical problem of position deviation of the rotating target piece assembly during installation, and also solve the technical problem of falling of the rotating target piece assembly during disassembly and assembly.

[0031] Preferably, in step S1, a mobile device and a background processing terminal are used to realize the control movement of the assembly and disassembly mechanism, wherein the mobile device includes a horizontal lateral movement mechanism, a horizontal longitudinal movement mechanism and a vertical movement mechanism, wherein the horizontal longitudinal movement mechanism is installed on the horizontal lateral movement mechanism, and the horizontal lateral movement mechanism can drive the horizontal longitudinal movement mechanism to move horizontally; the vertical movement mechanism is installed on the horizontal longitudinal movement mechanism, and the horizontal longitudinal movement mechanism can drive the vertical movement mechanism to move horizontally and longitudinally; the assembly and disassembly mechanism is installed on the vertical movement mechanism, and the vertical movement mechanism can drive the assembly and disassembly mechanism to move vertically, and the vertical movement mechanism serves as a supporting structure of the assembly and disassembly mechanism;

[0032] The moving device is further provided with a first motor, a second motor and a third motor, wherein the first motor is used to drive the horizontal longitudinal moving mechanism to move horizontally, the second motor is used to drive the vertical moving mechanism to move horizontally and longitudinally, and the third motor is used to drive the disassembly and assembly mechanism to move vertically;

[0033] The first motor, the second motor and the third motor are respectively provided with a first control module, a second control module and a third control module; the first control module, the second control module and the third control module are used to respectively receive instructions sent by the background processing terminal, and respectively control the first motor, the second motor and the third motor to rotate forward or reverse;

[0034] The disassembly and assembly mechanism is also provided with a third control module and a fourth control module;

[0035] The third control module is used to receive the instruction sent by the background processing terminal, and control each screw motor to rotate forward or reverse at the same time;

[0036] The fourth control module is used to receive instructions sent by the background processing terminal and control the start and stop of each of the vacuum pumping devices.

[0037] Preferably, in step S1, the central axis is brought into contact with the rotating axis and the center line of the central axis is ensured to coincide with the center line of the rotating axis by the following method:

[0038] S1.1. Establish an XYZ coordinate system, and set a first coordinate measuring point, a second coordinate measuring point, and a third coordinate measuring point on the horizontal lateral moving mechanism, the horizontal longitudinal moving mechanism, and the vertical moving mechanism, respectively;

[0039] S1.2. Connect the central axis with the rotating axis and ensure that the center line of the central axis coincides with the center line of the rotating axis. At this time, measure the coordinate values ​​of the installation end position of the first coordinate measuring point, the second coordinate measuring point, and the third coordinate measuring point respectively;

[0040] S1.3, separate the central axis from the rotating axis to the disassembly end position where the rotating target assembly can be taken out, at this time, respectively measure the disassembly end position coordinate values ​​of the first coordinate measuring point, the second coordinate measuring point, and the third coordinate measuring point, and use the disassembly end position coordinate value as the initial position coordinate value of the moving device;

[0041] S1.4. Convert the installation end position coordinate value and the disassembly end position coordinate value into the operation time of the first motor, the second motor and the third motor on the background processing terminal.

[0042] This solution adopts a coordinate positioning method to improve the alignment degree of the "axis-to-axis" process and solve the technical problems of difficult alignment or large alignment errors that may occur in the "axis-to-axis" process due to visual errors when manual operation is used.

[0043] Preferably, in step S2, when disassembling the old rotating target piece assembly, the mobile device is located at the initial position, the background processing terminal sends a disassembly instruction to the mobile device, the mobile device transports the disassembly mechanism to the installation terminal position, and then the background processing terminal sends an execution disassembly instruction to the disassembly mechanism, the disassembly mechanism starts to disassemble the old rotating target piece assembly, and after the disassembly is completed, the background processing terminal sends a reset instruction to the mobile device to reset the mobile device to the initial position;

[0044] In step S3, when installing a new rotating target assembly, the background processing terminal sends an installation instruction to the mobile device, and the mobile device transports the disassembly and assembly mechanism to the installation terminal position. Then the background processing terminal sends an execution installation instruction to the disassembly and assembly mechanism, and the disassembly and assembly mechanism starts to install the old rotating target assembly.

[0055] The disassembly and assembly mechanism 200 is provided with a central axis 201 corresponding to the rotating axis 103, and the central axis 201 has the same cross-sectional diameter as the rotating axis 103. When disassembling the rotating target sheet assembly, the end of the central axis 201 can abut against the opposite end of the rotating axis 103, and the center line of the central axis 201 coincides with the center line of the rotating axis 103;

[0056] The disassembly and assembly mechanism 200 is provided with a transfer assembly, which can be adsorbed and connected with the rotating target sheet assembly. When the end of the central axis 201 abuts against the end opposite to the rotating axis 103, the transfer assembly can drive the rotating target sheet assembly to move on the central axis 201 and the rotating axis 103.

Then, by utilizing the principle of concentric axes, the rotating target piece assembly can be disassembled and assembled in an "axis-to-axis" manner, and it can be moved to the central axis 201 or the rotating axis 103 accordingly. At the structural level, the accuracy of the target piece installation position can be improved, the disassembly and assembly efficiency can be improved, the technical problem of position deviation of the rotating target piece assembly during installation is solved, and the technical problem of falling of the rotating target piece assembly during disassembly and assembly is also solved.
