Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the special welding device for the 500 MHz high-frequency cavity system in this embodiment includes a high-frequency cavity main body 1, a lifting structure 2 is arranged at the bottom of the high-frequency cavity main body 1, and an adjusting structure 3 is arranged at the top of the high-frequency cavity main body 1.

[0023] The lifting structure 2 includes a bottom tray 201, a limiting port 202, a connecting rod 203, a flange support plate 204, a threaded barrel 205 and a screw 206. The bottom tray 201 is attached to the bottom of the high-frequency cavity main body 1. A limiting port 202 is opened at the center of the bottom tray 201. A connecting rod 203 is fixedly installed at the bottom of the bottom tray 201. A flange support plate 204 is fixedly installed at the bottom of the connecting rod 203. A threaded barrel 205 is fixedly installed inside the bottom tray 201, and a screw 206 is threadedly connected inside the threaded barrel 205.

[0024] The adjusting structure 3 includes an upper suspension plate 301, a first gear 302, a second gear 303, a rotating rod 304, a protective pad 305 and an adjusting lifting rod 306. An upper suspension plate 301 is rotatably installed outside the screw 206. A first gear 302 is movably installed at the top of the upper suspension plate 301. A second gear 303 is movably installed at the top of the upper suspension plate 301. A rotating rod 304 is fixedly installed inside the second gear 303. A protective pad 305 is fixedly installed at the bottom of the upper suspension plate 301. An adjusting lifting rod 306 is movably installed inside the upper suspension plate 301.

[0025] In Figure 2 During operation, the rotation of two screws 206 drives the threaded barrel 205 to move, adjusts the distance between the bottom tray 201 and the upper suspension tray 301, and hoists and fixes the high-frequency cavity body 1.

[0026] In Figure 3 During operation, the lifting rod 306 is adjusted to limit the movement range of the bottom tray 201 and the upper suspension tray 301, preventing the high-frequency cavity body 1 from being unstably hoisted due to deviation when the bottom tray 201 moves.

Rotating the rotating rod 304 drives the second gear 303 to rotate, causing the two first gears 302 and the screws 206 to rotate simultaneously, so that the position of the upper suspension tray 301 can be adjusted according to the height of the high-frequency cavity body 1. After the upper suspension tray 301 is attached to the top of the high-frequency cavity body 1, the hoisting of the high-frequency cavity body 1 is completed, and the stability of the high-frequency cavity body 1 is well maintained during the hoisting process, solving the problem that the accelerator is usually too large in size, and a hoisting device is also required for processing and welding the accelerator. In order to accurately ensure the stability of the hoisting of the high-frequency cavity device during the welding of the accelerator.
