Four-wing type radio frequency quadrupole field accelerator cavity mounting platform and assembling method thereof

Abstract

The invention relates to a four-wing type radio frequency quadrupole field accelerator cavity mounting platform and an assembling method thereof. The four-wing type radio frequency quadrupole field accelerator cavity mounting platform comprises a main welding bottom frame, two linear guide rails are assembled on the main welding bottom frame, a plurality of sliding blocks are assembled on the linear guide rails, and a plurality of side wing plates are evenly arranged on the two sides in the length direction of the main welding bottom frame at intervals. A plurality of worm and gear adjusting assemblies are included, and each worm and gear adjusting assembly comprises a bottom adjusting device and a lifting jack assembled on the bottom adjusting device, and the worm and gear adjusting assemblies are assembled below side wing plates. A plurality of three-dimensional adjustable assemblies are included and comprise sliding rail tables, support assemblies and fine adjustment assemblies. The sliding rail tables are assembled on the sliding blocks, the support assemblies are movably assembled on the sliding rail tables, the fine adjustment assemblies are assembled on the support assemblies, and the support assemblies are configured to adjust the left-right position of an accelerator cavity. According to the platform, coarse adjustment and fine adjustment are carried out on the cavity in the beam height direction through the upper-layer adjusting mechanism and the lower-layer adjusting mechanism, and the adjustment precision and efficiency of cavity installation are improved.

Description

technical field [0001] The invention relates to a cavity installation platform of a four-wing radio frequency quadrupole field accelerator and an assembly method thereof, belonging to the technical field of mechanical assembly. Background technique [0002] The four-wing radio frequency quadrupole field (Radio Frequency Quadrupole, RFQ) accelerator cavity is the core component of the low-energy section of the particle accelerator. And adjust the cavities of each section, and ensure the assembly accuracy between the cavities of each section. [0003] At present, although the support of the four-wing RF quadrupole field cavity can also realize the overall adjustment and single-segment support adjustment functions, but due to the heavy weight of the cavity, the support deformation is severe, and the adjustment of the adjustment device in the height direction is difficult to achieve; In addition, the length of the existing four-wing RF quadrupole field cavity is increased, and ...

Problems solved by technology

[0003] At present, although the support of the four-wing RF quadrupole field cavity can also realize the overall adjustment and single-segment support adjustment functions, but due to the heavy weight of the cavity, the support deformation is severe, and the adjustment of the adjustment device in the height direction is difficult to achieve; In addition, the length of the existing four-wing RF quadrupole field cavity is increased, and the site space is limited, and the existing support structure cannot bear the longer and heavier cavity assembly; moreover, according to the site conditions, it is necessary to The cavity and its support are hoisted to the test site as a whole, which requires consideration of the load-bearing and deformation of the cavity and support during the hoisting process; these problems make the existing support structure unsuitable for the ultra-long four-wing RF quadrupole field Cavity assembly, adjustment and hoisting
