Problems solved by technology

[0005] (1) The support device itself has additional force on the material grid, which needs to be arranged symmetrically and is not suitable for one-sided arrangement;
[0006] (2) Even if it is symmetrically arranged, the overall force is balanced, but the initial force is also received locally at the lattice support, so that the lattice increases the local force
The existence of this initial force will have a more adverse effect on the storage grid when it is superimposed with the seismic load during an earthquake

Embodiment 1

[0036] This embodiment discloses a support device, which can be applied to laterally support the fuel storage grid of a nuclear power plant, and of course can also be used to support other facilities that require shock resistance or vibration reduction. This embodiment takes the fuel storage grid (hereinafter referred to as the grid) installed in the fuel storage room (hereinafter referred to as the storage room) as an example to describe in detail. The support device improves the stress state of the grid during normal or earthquake conditions, thereby Improve the shock resistance of the trellis.

[0037] Such as figure 1 , figure 2 As shown, the support device in this embodiment mainly includes a support rod 1, a sleeve 5 and a buffer mechanism, wherein: one end of the sleeve 5 is provided with an opening; Protrude from the open end of the sleeve 5; the buffer mechanism is arranged in the sleeve 5, including a first buffer unit and a second buffer unit, both of the first b...

Embodiment 2

[0058] This embodiment discloses a storage system, including a grid set in the storage room and the support device in embodiment 1, the support device is set between the storage room and the grid, wherein the support device is a grid Provide elastic support for buffering external forces.

[0059] Specifically, a hole adapted to the support rod 1 is provided on the grid side plate 10, and is used to allow the screw end of the support rod 1 of the support device to pass through the hole, and at the same time, the base 9 of the support device is fixedly connected to the On the side wall 16 of the storage room. Place the grid in the storage room, and adjust the length of the support device by adjusting the nut 6 according to the distance between the side panel 10 of the grid and the side wall 16 of the storage room, so as to adapt to different side panels 10 of the grid and the side wall 16 of the storage room. spacing between walls 16 .

[0060] Further, the number of the suppo...

Abstract

The invention discloses a support device, which includes a support rod, a sleeve, and a buffer mechanism, one end of the sleeve is provided with an opening; one end of the support rod is disposed in the sleeve, and the other end is protruding from the open end of the sleeve; the buffer mechanism is arranged in the sleeve, including a first buffer unit and a second buffer unit, and both the first buffer unit and the second buffer unit act on the on the support rod, and the resultant force of the support rod is kept zero under the action of the first buffer unit and the second buffer unit. Correspondingly, the present invention also discloses a storage system comprising the supporting device. The supporting device of the invention does not generate any initial external force itself, and has the functions of anti-shock and vibration reduction, flexible layout and wide application range.

Description

technical field [0001] The invention belongs to the technical field of engineering, and in particular relates to a supporting device and a storage system. Background technique [0002] The problem of anti-seismic and vibration reduction of engineering facilities is very important, especially at present, with the improvement of safety requirements, nuclear power equipment or facilities are required to be improved to meet stricter safety requirements for anti-seismic and vibration reduction. At present, in order to reduce the response to earthquakes, these equipment or facilities generally adopt elastic support devices to achieve the effects of earthquake resistance and vibration reduction. [0003] In the Chinese patent CN201510072558.5 (the announcement number is CN104653697A, the publication date is 2015-05-27), an elastic support device for fuel storage grids is disclosed, which can reduce the impact of earthquakes and ensure that the fuel grids are not affected by earthqu...
