Description
Technical Field
The invention belongs to the technical field of engineering, and particularly relates to a supporting device and a storage system.
Background
The problems of earthquake resistance and vibration reduction of engineering facilities are very important, and particularly at present, nuclear power equipment or facilities are required to be improved to meet stricter earthquake resistance and vibration reduction safety requirements along with the improvement of safety requirements. At present, in order to reduce the response to earthquake, the equipments or facilities generally adopt an elastic supporting device to achieve the effects of earthquake resistance and vibration reduction.
An elastic supporting device for a fuel storage grid is disclosed in chinese patent CN201510072558.5 (publication No. CN104653697A, published as 2015-05-27), which can reduce the influence of earthquake, ensure that the fuel grid is less stressed during earthquake, avoid collision, and be widely used around the grid to effectively protect the grid structure. Although the elastic support device can reduce vibration, the fuel grillage needs to bear the additional acting force brought by the support device after being installed, so that the stress balance can be ensured only by symmetrically arranging and supporting the single fuel grillage; for a plurality of fuel grillworks, the grillworks are connected by rigid supports, and the vibration reduction supports connected with the side walls are also symmetrically arranged, so that the integral stress balance can be ensured; in earthquake, the symmetrical arrangement is also needed, so that the external load action in two opposite directions can be reduced by the spring and the fluid damping, and the balance position can be restrained. However, when a single-sided arrangement of the fuel lattice is required, it becomes exceptionally difficult to constrain its holding in an equilibrium position.
At present, the lateral supporting device for buffering has the following defects:
(1) the supporting device has extra acting force on the material grillwork, needs to be symmetrically arranged and is not suitable for being arranged on one side;
(2) even if the grid is symmetrically arranged and the overall stress is balanced, the initial force is locally applied to the support of the grid, so that the local stress of the grid is increased. The presence of such initial forces, superimposed on the seismic loads, during an earthquake, will have a more negative effect on the storage lattice.

The piston head 21 divides the internal cavity of the sleeve 5 into two chambers, a first chamber 17 in which a first damping unit is disposed and a second chamber 18 in which a second damping unit is disposed.
Further, the first damping unit includes a first compression spring 7, and the second damping unit includes a second compression spring 8. The first compression spring 7 is sleeved on the piston tail 22 of the piston end 2 of the support rod 1, wherein: one end of the first compression spring 7 is abutted against the baffle 3, and the baffle 3 can prevent the first compression spring 7 from being separated from the sleeve 5; the other end of which abuts against the piston end 2 of the support rod 1, more precisely against the piston head 21.
