A radial support device for seismic protection of a large-scale high-stability target chamber

Abstract

The invention discloses a seismic-protection redial supporting device for a large-size high-stability target chamber. The seismic-protection redial supporting device is used for supporting the target chamber and comprises a plurality of supporting modules with central planes located on the same horizontal plane, wherein the supporting modules are evenly distributed on the periphery of the target chamber. In the supporting modules, one end of each supporting connection block is fixedly connected with the target chamber, the upper portion and the lower portion of the other end of each supporting connection block are respectively connected with one end of an upper steel plate and one end of a lower steel plate, one end of a middle steel plate is arranged between the other end of the upper steel plate and the other end of the lower steel plate and is connected with the other end of the upper steel plate and the other end of the lower steel plate through vertical bolts, and the other end of the middle steel plate is fixedly connected with an embedded steel plate embedded into a foundation of the target chamber. The seismic-protection redial supporting device uses three steel plates having high frictional damping characteristics as radial supporting structures of the target chamber, can meet the micron-dimension stability requirement of the target chamber and does not constraint the target chamber. The structure that the three steel plates are connected through the vertical bolts is adopted, multiple vertical bolts are simultaneously sheared off under the seismic condition, and the target chamber is not disastrously destructed.

Description

technical field [0001] The invention relates to a radial support device mainly used for supporting a target chamber in an optical experiment, in particular to an earthquake protection radial support device for a large-size and high-stability target chamber. Background technique [0002] Large-size target chambers are widely used in various scientific devices because they can provide experimental places for optical physics experiments and realize stable support for related optical components and diagnostic equipment. Due to the limitation of the overall arrangement requirements of the experimental devices, most of the existing target chambers are high-tower structures with poor safety performance and lateral support rigidity. For target chambers with small structural dimensions, due to the inconspicuous tower structure, generally no radial support is required. However, for large-sized target chambers, due to their high cost, the impossibility of repeated manufacturing in a s...

Problems solved by technology

Its disadvantage is that it will inevitably introduce over-constraint, which will cause deformation of the surface of the target chamber and affect the normal use of the diagnostic equipment supported on it.

At the same time, due to the hard connection between the target room and the foundation, when the energy caused by the earthquake is greater than the energy dissipated by the viscoelastic material, the energy will react on the target room, which may endanger the safety of the target room. In extreme cases May cause damage to the target chamber, leading to irreparable consequences
