Embodiment Construction
[0034] A combined vibration isolator 10 for an accelerator of the present invention is installed between the bottom surface of the upper dipole magnet and the bottom support of a fast-cycle synchrotron to reduce the vibration of the dipole magnet from being transmitted to the support. like figure 1 , figure 2 As shown, the vibration isolator 10 may include: a flange top cover 1 , a push plate 2 , a housing 3 , a bottom cover 4 , a connecting column 5 , a disc spring set 6 and a metal rubber 7 .
[0035] like Figure 1 to Figure 3 As shown, the flange top cover 1 can be assembled on the bottom surface of the two-pole magnet of the fast-cycle synchrotron; the steel flange top cover 1 is disc-shaped, and a plurality of U U-shaped opening 11, the sides of U-shaped opening 11 are open outwards, and can be used for bolts 12 to slide in from the outside. Corresponding screw holes are also provided on the bottom surface of the magnet, and the flange top cover 1 can be quickly fixe...

The invention provides a combined vibration isolator of an accelerator. The combined vibration isolator of the accelerator is installed between a magnet of the accelerator and a support of the accelerator and comprises a flange plate top cover, a shell, a bottom cover, a connecting column, a belleville spring set and metal rubber, wherein the flange plate top cover can be assembled on the bottom surface of the magnet, the bottom of the shell can be assembled on the top surface of the support, the bottom cover is fixed to the bottom of the shell, the middle of the bottom cover extends and protrudes towards the flange plate top cover so that a containing part can be formed, a containing space is formed in the containing part, a central hole for the connecting column to pass through in an assembled mode is formed in the top of the containing part, the connecting column is fixedly connected to the flange plate top cover, the other end of the connecting column penetrates through the central hole to be fixed inside the metal rubber in the containing space, the belleville spring set is arranged outside the containing part in a sleeved mode, the top of the belleville spring set abuts against the flange plate top cover, and the bottom of the belleville spring set abuts against the bottom cover. The combined vibration isolator of the accelerator is small in size, high in bearing capacity, resistant to fatigue, resistant to radiation, and small in creep amount.
Description
technical field [0001] The invention relates to vibration isolation technology, in particular to a combined vibration isolator for an accelerator with small size, high load, fatigue resistance, radiation protection and small creep. Background technique [0002] Most devices in the field of accelerators have to consider the problem of vibration isolation. The two-pole magnet of the fast-cycle synchrotron (RCS) in the China Spallation Neutron Source (CSNS) is excited by a resonant power supply with a DC bias and a repetition frequency of 25 Hz. serious vibration problems. The China Spallation Neutron Source mainly considers the problem of active vibration reduction. Due to its heavy equipment (a single magnet weighs up to 25 tons), and the limitation of the beam current and the height of the support, the installation height reserved for the vibration isolator is only 70mm. It is difficult for existing vibration isolator products to meet the technical requirements of such a sm...
