Description

Technical Field

[0001] The invention belongs to the field of full-size negative ion sources, and in particular relates to a turnover mechanism system of a full-size negative ion source. Background Art

[0002] The flipping mechanism system of the full-size negative ion source is a key component for realizing the installation of the full-size negative ion source in the NNBI system (neutral beam injection system based on negative ion source). Its main function is to flip the full-size negative ion source, so as to realize the installation of the full-size negative ion source. The commonly used ion source flipping system now adopts the method of crane hoisting. This flipping method uses a crane to hoist and flip. Generally, it is necessary to drill holes on the negative ion source to install a lifting ring, use a shackle on the lifting ring, and then use a lifting belt to flip it. Such an operation has certain deformation variables for the full-size negative ion source. There is uneven force during the hoisting process, and the weight of the full-size negative ion source is very large, which will cause deformation variables to the ion source during the hoisting process. For ion sources that produce larger deformation variables, they do not meet the requirements of the NNBI system experiment.

[0003] As magnetic confinement nuclear fusion research becomes more mature, the size of fusion reactors is getting larger and larger, and the plasma parameters are getting higher and higher, the requirements for the hoisting of full-size negative ion sources are also getting higher and higher. With high automation and simple operation, the flip mechanism system has become the first choice for the future NNBI ion source flip installation.

[0004] The flipping mechanism system is a key component in the installation process of the full-size negative ion source. Its working performance plays a vital role in the steady-state operation of the entire full-size negative ion source. Therefore, it is of great significance to carry out the design research of the flipping mechanism system. Summary of the invention

[0005] Considering that with the increasing maturity of magnetic confinement nuclear fusion research, the size of fusion reactor devices is getting larger and larger, and the plasma parameters are getting higher and higher, the existing flipping mechanism system is difficult to meet the needs of future negative ion source flipping installation. Compared with the traditional crane lifting flipping method, the operation is complicated and the efficiency is low. The present invention provides a flipping mechanism system for a full-size negative ion source, which is simple to operate, reduces labor intensity, and improves the flipping efficiency. The present invention can be used to flip a full-size negative ion source, and has higher flipping stability and improves the flipping efficiency.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] A flipping mechanism system for a full-size negative ion source, used for flipping the full-size negative ion source, comprises a guide support component, a flipping component and a driving component;

[0008] The guide support assembly includes two connecting rod support seats arranged at intervals and 12 connecting support seats arranged in the vertical direction;

[0009] The flip assembly comprises two flip arms and a clamping portion arranged between the flip arms, one end of the flip arm is hinged between two fixed support seats, and the clamping portion cooperates with the flip arm to form a fixed position for fixing the full-size negative ion source to be flipped;

[0010] The driving assembly includes a driving member and a connecting flange, one end of the connecting flange is hinged to the mounting surface, and the other end is hinged to the flip arm. The driving member includes a fixed end and a telescopic end. The fixed end of the driving member is fixed inside the flip arm, and the telescopic end of the driving member is hinged to the anti-flip arm.

[0011] Furthermore, the guide support assembly includes two connecting rod support seats arranged at intervals, two connecting rods and 12 connecting support seats arranged in the vertical direction; one side of the connecting rod support seat is provided with 4 connecting rod support seat lifting ears and 6 connecting support seats to facilitate lifting after flipping, and the other side of the connecting rod support seat is provided with 6 connecting support seats. The two connecting rod support seats are fixed by bolt connection through two connecting rods.

[0012] Furthermore, one end of the flip arm of the flip assembly is hinged between two fixed support seats, and the clamping portion cooperates with the flip arm to form a fixed position for fixing the full-size negative ion source to be flipped.

[0013] Furthermore, the bottom end of the flip assembly adopts a pallet-shaped structure, the material of which is carbon steel, and 6 right-angle support seats are respectively arranged on both sides of the pallet base to give it higher supporting strength.

[0014] Furthermore, 36 bolt holes are punched on the pallet base for fixing the flip assembly, and 15 square plates are washed out inside it to reduce its own weight.

[0015] Furthermore, the two driving members are parallel to each other.

[0016] Furthermore, two square configuration blocks are used at the bottom of the driving box, which on the one hand increase the weight of the driving assembly and on the other hand serve to fix and support the driving assembly.

[0017] Beneficial effects:

[0018] In order to be applied to a full-size negative ion source, the present invention adopts a layer-by-layer fixing method, so that the force is evenly applied during the flipping process, and no deformation occurs during the flipping process. The present invention has a high degree of automation, is simple to operate, reduces labor intensity, improves flipping efficiency, and compared with the traditional crane method, reduces the deformation of the full-size negative ion source during the flipping process. The present invention realizes the function of simply flipping the full-size negative ion source by fixing the full-size negative ion source on the flipping mechanism, greatly improving the stability of the flipping.

The full-size negative ion source is fixed to the two connecting rod support seats 6 through 12 connecting support seats 11. The upper end of each connecting support seat 11 has 5 M20 bolt holes for fastening the full-size negative ion source, and the bottom end of the connecting support seat 11 has 4 M20 bolt holes for connecting the two connecting rod support seats 6. The top ends of the two connecting rod support seats 6 are connected by the first connecting rod column 10 and the second connecting rod column 12, and the bottom end of the connecting rod support seat 6 is connected to the guide support assembly tray 9 by M30 bolts. The guide support assembly tray 9 has 28 M20 bolt holes for fixing the full-size negative ion source. The connecting rod support seat ear 7 is arranged on the connecting rod support seat 6. After the full-size negative ion source is turned over, the connecting rod support seat ear 7 is connected by a crane, and the full-size negative ion source is hoisted at the interface of the vacuum chamber cavity, which greatly reduces the possibility of deformation after turning over. The M30 bolt sleeve 8 is arranged on the connecting rod support seat 6 and the guide support component tray 9, and is respectively connected to the connecting rod support seat 6 and one end of the guide support component tray 9, which is a tool for supporting and rotating a fixing bolt and nut for the guide support component. The guide support component tray 9 is used to fix the supporting outer flange of the full-size negative ion source, which is the basis for fixing the entire full-size negative ion source, and is also the basis for connecting the full-size negative ion source with the guide support component, providing support and fixing.

[0028] Preferably, one side of the connecting rod support seat 6 is provided with 4 connecting rod support seat lifting ears 7, and the connecting rod support seats 6 are 6 in number. Six connecting rod support seats 11 are provided on the other side of the connecting rod support seat, and the full-size negative ion source is fixed on the connecting rod support seat 11 through the connecting rod support seat 6. After flipping, the full-size negative ion source is hung at the interface of the vacuum chamber cavity by hoisting the 4 connecting rod support seat lifting ears 7 through the crane. The upper and lower connecting rod support seats 6 are fixed by bolt connection through the first connecting rod column 10 and the second connecting rod column 12. The connecting support seat 11 is as follows Figure 2 The triangular sheet structure shown is preferably provided with 6 evenly spaced at the bottom and 6 evenly spaced at the top.

[0029] like Figure 3 As shown, the described turnover assembly adopts the concave frame structure, comprises two turnover arms 13, two driving housings 4, the first square counterweight 5, the second square counterweight 17, a guide support assembly is arranged between the turnover arms 13, one end of the turnover arm 13 is hinged between two fixed support seats 19, and the clamping portion cooperates with the turnover arm 13 to form a fixed position for fixing the full-size negative ion source to be turned over. The bottom end of the turnover assembly adopts a support plate-shaped structure, and its material is carbon steel, and the tray base 14 both sides are respectively provided with 6 right-angle support seats 15, so that it has higher support strength, and the tray base 14 is punched with 36 bolt holes for fixing the guide support assembly, and 15 square blocks are washed out in order to reduce its own counterweight. The driving housing 4 assembles the shaft, sleeve, gear and other related parts in the turnover mechanism into an integral body, keeps the correct mutual position between them, and transmits motion or power in a coordinated manner according to a certain transmission relationship, i.e., a driving member 18 is arranged in the driving housing 4. The first square counterweight 5 and the second square counterweight 17 both adopt a square structure, which increases the force-bearing area and improves the stability of the overall flipping mechanism. At the same time, it increases its own counterweight, providing effective support for the flipping of the full-size negative ion source.

[0030] like Figure 4 As shown, the driving assembly includes a driving member 18 and a connecting flange 16, one end of the connecting flange 16 is hinged to the mounting surface, and the other end is hinged to the flip arm 13, the driving member 18 includes a fixed end and a telescopic end, the fixed end of the driving member 18 is fixed inside the flip arm 13, and the telescopic end of the driving member 18 is hinged to the flip arm 13. The bottom of the driving box 4 of the driving member 18 adopts two square configuration blocks, which increase the weight of the driving assembly on the one hand, and play a role in fixing and supporting the driving assembly on the other hand.

[0031] Furthermore, 15 carbon steel counterweights 2 are placed on the top of the flip arm 13 to improve the overall flipping stability. The counterweights 2 are used to increase their own counterweights, provide part of the power required for flipping the flip assembly, and improve the stability of the full-size negative ion source.

[0032] First, the turning mechanism of the full-size negative ion source is turned by driving. The ground electrode support outer flange is first fixed to the guide support component tray 9 by bolts, and then the connecting support seat 11 is fixed to the ground electrode support outer flange by bolts, and the bottom of the connecting support seat 11 is fixedly connected to the connecting rod support seat 6.
