DETAILED DESCRIPTION

[0026] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] In order to improve the installation accuracy of the voltage multiplier column 2 on the tank assembly 1 in a large electron accelerator, the utility model discloses an electron accelerator voltage multiplier column base. Figures 1 to 6 As shown, the electron accelerator voltage-multiplier column base is used to connect the tank assembly 1 and the voltage-multiplier column 2. The electron accelerator voltage-multiplier column base includes a base module, to which are connected a first connector 3 and a second connector 4. The first connector 3 is used to connect the base module to the tank assembly 1, and the second connector 4 is used to connect the base module to the voltage-multiplier column 2. The base module is also connected to several distance-adjusting mechanisms, which set the distance between the base module and the tank assembly 1 to a first distance and the distance between the base module and the voltage-multiplier column 2 to a second distance. The distance-adjusting mechanisms are used to adjust the first and / or second distances.

[0030] During assembly of a large electron accelerator, it is difficult to ensure that the length of the voltage multiplier column 2 is perpendicular to the horizontal plane after it is installed on the tank assembly 1. Therefore, the present invention connects the tank assembly 1 and the voltage multiplier column 2 via the electron accelerator voltage multiplier column base. By operating a distance adjustment mechanism to adjust the first distance and / or the second distance, the verticality of the voltage multiplier column 2 with the horizontal plane is indirectly adjusted, thereby achieving higher installation accuracy of the voltage multiplier column 2.

[0031] In detail, there are many ways to connect the first connecting member 3 and the second connecting member 4, which can be bolted, welded, or riveted. The distance adjustment mechanism can use an adjusting screw sleeve 7 to adjust the distance, or an adjusting rod to adjust the distance, or an airbag to adjust the distance by controlling the size of the airbag by the amount of inflation, thereby adjusting the first distance and / or the second distance. However, no matter which method is used for the first connecting member 3, the second connecting member 4, and the distance adjustment mechanism, after the distance adjustment mechanism is adjusted into place, the first connecting member is used to connect the base module and the tank assembly 1, and the second connecting member is used to connect the base module and the pressure multiplier column 2.

[0032] The first connecting member 3 or the second connecting member 4 can have various positional relationships with the distance adjustment mechanism, such as being arranged side by side or in combination.

[0033] Take the distance adjustment mechanism between the base module and the tank assembly 1, and the first connector 3 connecting the base module and the tank assembly 1, as examples. When the distance adjustment mechanism uses an airbag and the first connector 3 is riveted, the first connector 3 and the distance adjustment mechanism can be arranged side by side. For example, the two ends of the airbag are connected to the tank assembly 1 and the base module respectively. When the airbag is adjusted to the appropriate size, the tank assembly 1 and the base module are riveted.

[0034] When the distance adjustment mechanism adopts the adjusting screw sleeve 7 and the first connecting member 3 is connected with the first bolt 8, the first bolt 8 is inserted into the adjusting screw sleeve 7. At this time, the first connecting member 3 and the distance adjustment mechanism are combined, which will be explained in detail below.

[0035] In this embodiment, if Figures 1 to 6 As shown, only a distance adjustment mechanism for adjusting the first distance is provided, that is, the distance adjustment mechanism only adjusts the distance between the base module and the tank assembly 1. During the installation of the electron accelerator voltage multiplier column base, the horizontality of the base module is ensured by adjusting each first distance, thereby ensuring that the voltage multiplier column 2 has a high verticality. Specifically, the base module includes a first connecting rod 5 and a second connecting rod 6 connected to the first connecting rod 5, the first connecting member 3 is used to connect the first connecting rod 5 and the tank assembly 1, the second connecting member 4 is used to connect the second connecting rod 6 and the voltage multiplier column 2, and the distance adjustment mechanism is provided on the first connecting rod 5. The utility model enables the tank assembly 1 and the voltage multiplier column 2 to be connected to different components respectively through the provision of the first connecting rod 5 and the second connecting rod 6, and the assembler has sufficient space to install the voltage multiplier column 2 and adjust the distance adjustment mechanism, which facilitates the assembly of large electron accelerators. In other embodiments, in order to further ensure the installation accuracy of the voltage multiplier column 2, a distance adjustment mechanism is also provided on the second connecting rod 6, so that both the first distance and the second distance can be adjusted.

[0036] In this embodiment, if Figure 1 As shown, three distance adjustment mechanisms are provided on the first connecting rod 5. Each distance adjustment mechanism is arranged in the same straight line and is evenly spaced. Two distance adjustment mechanisms are respectively provided at each end of the first connecting rod 5. The electron accelerator voltage multiplier column base of the present invention facilitates adjustment of the horizontality of the electron accelerator voltage multiplier column base by limiting the number and position of the distance adjustment mechanisms, particularly by providing the distance adjustment mechanisms at both ends of the first connecting rod 5. In other embodiments, the number of distance adjustment mechanisms may be five or seven, and the distance adjustment mechanisms may also be dispersed.

[0037] In this embodiment, if Figures 3 to 5 As shown, the distance adjustment mechanism and the first connecting member 3 are assembled in a combined arrangement. Specifically, the distance adjustment mechanism is an adjusting screw sleeve 7, and the first connecting member 3 is a first bolt 8. The adjusting screw sleeve 7 is sleeved on the outside of the first bolt 8, and the outside of the adjusting screw sleeve is provided with a first external thread. The first connecting rod 5 is provided with a first internal thread that cooperates with the first external thread. The tank assembly 1 is provided with a first threaded hole that cooperates with the first bolt 8. The distance adjustment mechanism and the first connecting member 3 are assembled as follows:

[0038] S1, screw each adjusting screw sleeve 7 into each first internal thread of the first connecting rod 5, and each adjusting screw sleeve 7 passes through the first connecting rod 5 until one end of each adjusting screw sleeve 7 abuts against the installation plane of the tank assembly 1;

[0039] S2, continue to rotate each adjusting screw sleeve 7 to adjust the first distance, that is, adjust the distance between the tank assembly 1 and the first connecting rod 5, until the first connecting rod 5 meets the installation level required by the large electron accelerator;

[0040] S3, insert the first bolt 8 into the hollow part of the adjusting screw sleeve 7, the adjusting screw sleeve 7 is sleeved on the outside of the first bolt 8, and the first bolt 8 is screwed into the first threaded hole until the first bolt 8 tightens the adjusting screw sleeve 7 and the first connecting rod 5 on the tank assembly 1.

[0041] In this embodiment, if Figure 1 As shown, there are two first connecting rods 5, each of which is connected to the two ends of the second connecting rod 6, and each of the first connecting rods 5 is arranged in parallel with each other. Therefore, six adjusting screw sleeves 7 are provided on the base module, and the six adjusting screw sleeves 7 are arranged in a two-by-three form, which can better adjust the horizontality of the electron accelerator voltage multiplier column base. The utility model facilitates the adjustment of the horizontality of the base module by providing two first connecting rods 5. In other embodiments, there are also two first connecting rods 5, but each first connecting rod 5 can be arranged at an angle to each other. Although considering the adjustment of the horizontality of the electron accelerator voltage multiplier column base, the mutually inclined arrangement of the first connecting rods 5 is not as convenient as the mutually parallel arrangement of the first connecting rods 5, the mutually inclined arrangement of the first connecting rods 5 increases the deformation resistance of the electron accelerator voltage multiplier column base.

[0042] In this embodiment, if Figures 1 to 6 As shown, the electron accelerator voltage-multiplier column base of the present invention includes, in addition to a base module, a connecting plate 9. At least two second connecting rods 6 are provided. In this embodiment, there are two second connecting rods 6, and the two second connecting rods 6 are parallel to each other. Both second connecting rods 6 are connected to the connecting plate 9, which has through-holes for connecting the second connecting member 4. Specifically, the two second connecting rods 6 are respectively disposed at either end of the connecting plate 9. In this embodiment, during the connection of the voltage-multiplier column 2 to the electron accelerator voltage-multiplier column base, the voltage-multiplier column 2 is abutted against the connecting plate 9, and then the second connecting member 4 is inserted through the through-holes in the connecting plate 9 to connect the voltage-multiplier column 2 to the second connecting rods 6. The provision of the connecting plate 9 in this utility model facilitates the stable fixing of the larger voltage-multiplier column 2 to the electron accelerator voltage-multiplier column base. In other embodiments, three second connecting rods 6 may be provided, and they may be arranged at an angle relative to each other. The angled second connecting rods 6 increase the overall strength of the connection between the connecting plate 9 and the second connecting rods 6, making the electron accelerator voltage-multiplier column base less susceptible to deformation due to the gravity of the larger voltage-multiplier column 2.

[0043] In this embodiment, if Figure 6As shown, the second connecting member 4 is a second bolt 10. The through-hole in the connecting plate 9 is provided with a second threaded hole that mates with the thread of the second bolt 10. The second connecting rod 6 also has a second threaded hole that mates with the second bolt 10. After the second bolt 10 is connected to the voltage multiplier column 2, the thread of the second bolt 10 mates with the second threaded hole in the connecting plate 9, and subsequently with the second threaded hole in the second connecting rod 6. By providing the second threaded hole in the through-hole in the connecting plate 9 that mates with the thread of the second bolt 10, the present invention allows the second bolt 10 to have a deeper engagement depth, facilitating a secure connection between the voltage multiplier column 2 and the base of the electron accelerator voltage multiplier column. In other embodiments, the second connecting member 4 can be a clamping member with a claw on its sidewall, one side of which is curved and the other side is flat. The through-hole in the connecting plate 9 is provided with a pawl that mates with the claw of the clamping member. The second connecting rod 6 also has a hole identical to the through-hole in the connecting plate 9. The clamping member and the pawl operate on the same principle as a ratchet pawl, and the clamping member can only enter the through-holes in the connecting plate 9 and the second connecting rod 6 in one direction.

[0044] In this embodiment, if Figure 1 As shown, the connecting plate 9 is connected to each second connecting rod 6 to form a connecting assembly. Two connecting assemblies are provided, spaced apart from each other. The gap between the two connecting assemblies is used to mount the accelerating tube of the electron accelerator. By providing two connecting assemblies, the present invention facilitates installation of the voltage multiplier column 2 while also providing space for the accelerating tube. In other embodiments, the number of connecting assemblies can be three, interconnected to form a triangle, with the gap in the center of the triangle being used to mount the accelerating tube.

[0045] At the same time, since the electron accelerator voltage multiplier column base of the present invention is used in an electron accelerator, the present invention also discloses an electron accelerator, which includes a tank assembly 1, a voltage multiplier column 2, and the electron accelerator voltage multiplier column base described above that connects the tank assembly 1 and the voltage multiplier column 2.

[0046] Specifically, in this embodiment, since the voltage multiplier column 2 is formed by two voltage multiplier column substrates connected to each other, Figures 4 to 6 As shown, in the electron accelerator of the present invention, the voltage multiplier column 2 is connected to the electron accelerator voltage multiplier column base via a fixed bent plate. Specifically, the voltage multiplier column base plate in the voltage multiplier column 2 is connected to the second connecting rod 6 in the electron accelerator voltage multiplier column base via a fixed bent plate.

[0047] The fixed bent plate includes a base plate 11, a vertical plate 12, and a reinforcing plate 13, all of which are arranged perpendicular to one another. The base plate 11 is connected to the second connecting rod 6. Specifically, the second bolt 10 passes through the base plate 11 and the connecting plate 9, and then connects to the second connecting rod 6. The vertical plate 12 is connected to the pressure multiplier column 2. Specifically, the vertical plate 12 is bolted to the pressure multiplier column base plate in the pressure multiplier column 2.

[0048] In summary, the utility model can adjust the verticality of the voltage multiplier column 2 and the horizontal plane by setting the distance adjustment mechanism, thereby improving the installation accuracy of the voltage multiplier column 2. And by setting the first connecting rod 5 and the second connecting rod 6, the tank assembly 1 and the voltage multiplier column 2 are respectively connected to different components, which is convenient for assembly. And by limiting the number and position of the distance adjustment mechanism, it is convenient to adjust the horizontality of the electron accelerator voltage multiplier column base. And by setting two first connecting rods 5, it is convenient to better adjust the horizontality of the electron accelerator voltage multiplier column base. And by setting the connecting plate 9, it is convenient to stably fix the larger voltage multiplier column 2 on the electron accelerator voltage multiplier column base. By setting a second threaded hole that matches the thread of the second bolt 10 on the through hole on the connecting plate 9, the thread depth of the second bolt 10 is deeper. And by setting two connecting assemblies, an installation position is reserved for the acceleration tube.

[0049] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
