Background
Along with the gradual emphasis on the shock-proof and shock-absorbing design, different shock-absorbing and shock-absorbing technologies are continuously available. The active anti-seismic damping means generally controls the movement of a heavy hammer by external energy to counteract the action of an earthquake, has obvious effect but huge cost, and is only used in important super high-rise buildings at present. The passive anti-seismic damping means generally consumes seismic energy by means of stress yielding or interface friction of replaceable parts and the like, is economical and simple and convenient to operate, but needs to be specially designed for different damping and anti-seismic targets. The characteristics of various floating objects and large size difference make a certain difficulty in implementation of a specific passive damping means.
The aim of enhancing the anti-overturning capacity of the floating object by adding the sliding layer to achieve shock absorption is a passive shock absorption means, and the passive shock absorption means has the advantages that: the operation is simple and feasible, and the method has considerable universality. By adding the sliding layer, the displacement capacity of the floating article under the action of an earthquake is improved, the load transmitted by friction is reduced, and the anti-overturning and shock-absorbing capacity of the floating article is improved on the premise of playing the original function of the floating article.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art, provide a damping device who reduces to float and put article bottom coefficient of friction that simple and easy, effect are showing, the price/performance ratio is high, reduce to float and put article destruction under the earthquake effect.
The utility model adopts the technical proposal that: a damping device for reducing the friction coefficient of the bottom of a floating article comprises a bottom plate, an upper panel, a floating article bottom fixing device and a ball layer;
the bottom plate is fixedly arranged on the ground or floor, the upper panel is arranged on the bottom plate in a floating mode, and a sliding layer is arranged between the bottom plate and the upper panel;
the sliding layer adopts the scheme that the top of the bottom plate is provided with a tetrafluoroethylene coating, and the bottom of the upper plate is provided with the tetrafluoroethylene coating; or the sliding layer adopts the scheme that a ball layer is added between the bottom plate and the upper panel;
and a floating article bottom fixing device which ensures that the floating article and the upper panel move in the same direction is arranged on the upper panel.
Preferably, the bottom plate is fixed to the ground or the floor by bolts.
Preferably, the bottom fixing device of the floating article is in a four-corner clamping mode or a bolt anchoring mode, and the bottom fixing device can be selected according to the characteristics of the floating article.
The utility model discloses an add the sliding layer and change the coefficient of friction with the contact surface. The floating article bottom fixing device is used for restraining the bottom of a floating article and is fixed on the upper panel to enable the floating article bottom fixing device and the upper panel to be adaptive in movement, and the specific form is not limited.
Has the advantages that: the utility model discloses at the sliding layer that article and the former coefficient of friction of contact surface contact site installation are less than both, reduce with the contact surface friction within a definite time, the earthquake increases the displacement ability of floating article, reaches the purpose of protecting floating article. The utility model is simple in operation, high-efficient economy can effectually reduce the friction of floating between article and contact surface, ensures that the floating article can not take place to topple under ground or floor motion and cause the destruction.
