Description
Technical Field
The invention relates to the technical field of building structures and equipment shock insulation, in particular to an anti-collision self-resetting two-dimensional shock insulation support.
Background
Between the two major seismic zones in china, the eurasia seismic zone and the pacific seismic zone, is one of the most serious countries in the world suffering from seismic hazards. Historically, severe earthquakes of more than 6 grades have occurred many times in Yangtze river delta and Zhu river delta, and in the Bohai area of Kyoto hoop, a major earthquake of more than 7 grades occurs every 44 years on average in nearly 300 years. With the acceleration of the urbanization process, a large amount of national wealth is rapidly concentrated into cities and city cluster areas. More than one third of established or proposed urban groups in China are located in areas where big earthquakes of more than 7 levels are likely to occur. The buildings which account for the majority of cities in China are reinforced concrete multi-storey and high-rise buildings which have wide use functions, and economic loss and casualties caused by the damage of the buildings cause great impact on national security and social stability. The earthquake is that when the stratum of the earth crust is in a complex stress state and the action of the earth stress exceeds the ultimate strength of the stratum at a certain position along with the continuous change of the earth crust, the stratum can be suddenly broken and dislocated, so that the earthquake is caused, and is transmitted to the earth surface in the form of elastic waves, so that an object with certain mass near the earth surface generates inertia force, and when the self seismic capacity of the object for resisting the inertia action is insufficient, the object is damaged. When the excellent period of the local vibration is closer to the natural vibration period of the object, the damage of the object is more serious. The natural vibration period of the object can be obviously changed by arranging a certain vibration isolation device on the object, so that the excellent period of the earthquake is avoided, the inertia force acting on the object is obviously reduced, the damage of the object under the action of the earthquake is reduced, and the safety of the object under the earthquake is improved.
The seismic isolation technology essentially prolongs the natural vibration period of the structure by reducing the rigidity of the seismic isolation layer, so that the rigidity of the seismic isolation layer is generally small, large deformation can occur under the action of wind load, crowd load and other loads, and even serious damage can occur in severe cases, so that the application of the seismic isolation technology also has limitation. Analyzing the efficiency of the time scale of the seismic isolation technology, the fact that only the short time of the seismic action really acts on the common seismic isolation technology is that much time is not effective or even counterproductive. Therefore, the ideal seismic isolation technology should not work at ordinary times, only work temporarily when the earthquake happens, and stop working after the earthquake is over. The application space is brought to the application of the earthquake short-term prediction and earthquake early warning technology, and at the present stage, the development of the earthquake short-term prediction technology is extremely difficult, but the earthquake early warning technology is developed vigorously, and after an earthquake occurs, the earthquake early warning technology can strive for precious but short time for seismic defense, and the short time makes the transformation of the traditional seismic isolation technology possible, by utilizing the principle that the light speed is faster than the seismic wave speed.
In addition, under many circumstances, because two buildings or two equipment are close apart from each other, the collision of two article can arouse because of vibrations to adjacent side, and under many circumstances, this kind of adjacent side can not be allowed to collide, consequently need restrict the deformation of isolation bearing, especially to the object of high-speed motion like high-speed train, can not cause the collision between two high-speed trains because of the existence of isolation bearing, the spacing scheme of vibrations direction will reduce shock insulation efficiency. In addition, the seismic isolation support can have residual plastic deformation under the action of strong shock, which affects the normal use of structures or equipment, for example, if a train has horizontal lateral residual deformation, the train can hardly enter the station, and the risk of collision can also be caused.

The upper cylinder piston 26 or the lower cylinder piston 27 can thus move freely, so that the upper or lower displacement of the guide rod core 23 is no longer limited and can be displaced. After the earthquake is finished, after a stable power supply is provided, the hydraulic servo system 9 is started, the hydraulic system working motor 13 is started, the electromagnetic valve 16 on the hydraulic loop is closed, the normally closed state is entered, the electromagnetic valve 16 of the oil outlet way is opened to store hydraulic oil into the oil cylinder in the hydraulic guide rod 6, the guide rod is restored to the original state and is limited to the support again, in addition, the oil quantity of the upper oil port and the lower oil port is controlled by utilizing the signal (external signal) of the displacement meter installed on the shock insulation support, the shock insulation support is restored to the original position, then the electromagnetic valve 16 of the oil outlet way is closed, the normally closed state is entered, and finally the hydraulic telescopic rod 12 is controlled to be withdrawn and reset.
