Description
Technical Field
The invention relates to the technical field of building structure and equipment vibration isolation, in particular to an anti-collision three-dimensional vibration isolation support which is started and moves a balance position after earthquake early warning.
Background
The two main seismic zones at China, namely the European and Pacific seismic zones, are one of the most serious countries in the world suffering from earthquake hazards. Historically, strong earthquakes of more than 6 levels have occurred many times in Yangtze river delta and Zhujiang delta, and in the Jinjin ring Bohai sea region, more than 7 levels of major earthquakes have occurred on average every 44 years in nearly 300 years. Along with the acceleration of the urban process, a great number of national wealths are rapidly concentrated to cities and urban cluster areas. And more than one third of established or planned urban clusters in China are located in areas where more than 7 grades of major earthquakes may occur. The vast majority of the buildings in the city of China are reinforced concrete multi-layer and high-rise buildings, the buildings have wide use functions, and economic losses and casualties caused by the damage of the buildings cause great impact on national safety and social stability. The earthquake is that the stratum is in a complex stress state, when the earth stress exceeds the limit strength of the stratum at a certain place along with the continuous change of the earth crust, the stratum is suddenly broken and dislocated, so that vibration is caused, the vibration is transmitted to the ground surface in the form of elastic waves, an object with certain mass near the ground surface is caused to generate inertia force, and when the earthquake resistance of the object against the inertia effect is insufficient, the object is damaged. The damage to the object is more serious when the excellent period of the local vibration is relatively close to the self-vibration period of the object. The self-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 vibration isolation technology essentially prolongs the self-vibration period of the structure by reducing the rigidity of the vibration isolation layer, so the rigidity of the vibration isolation layer is generally smaller, and under the action of wind load, crowd load and other loads, larger deformation and even serious damage can occur, so that the application of the vibration isolation technology is limited. Analysis of the time scale efficiency of the seismic isolation technique has found that in practice it is only a brief time of seismic action that is truly active for common seismic isolation techniques, and more time is inactive or even counter-active. Therefore, the ideal vibration isolation technology is not operated at ordinary times, and only when the earthquake is temporarily operated, the earthquake is ended and then the operation is stopped. The earthquake short-time forecasting and earthquake early warning technology brings application space for the application of the technology, and at the present stage, the development of the earthquake short-time forecasting technology encounters great difficulty, but the earthquake early warning technology is vigorously developed, when an earthquake happens, the earthquake early warning technology can fight for valuable but short time for earthquake fortification by utilizing the principle that the light speed is faster than the earthquake wave speed, and the short time makes the improvement of the traditional earthquake isolation technology possible.
In addition, in many cases, since two buildings or two devices are closely spaced, adjacent sides collide with two objects due to vibration, and in many cases, such adjacent sides cannot be allowed to collide, so deformation of the shock insulation support needs to be limited, and particularly for objects moving at high speed like high speed trains, the shock insulation efficiency cannot be reduced due to collision between two trains caused by the existence of the shock insulation support. In addition, the shock-insulating supports also have residual plastic deformations under the effect of strong shocks, which affect the normal use of the structure or the equipment, for example, trains can be difficult to get into station if they have horizontal lateral residual deformations, which also lead to a risk of collisions. For some civil buildings, which are similar to the devices of trains and through which rail traffic passes, the devices need to be damped at ordinary times, but large horizontal deformation is not allowed.

Working principle: when an earthquake occurs, the opening and self-recovery control device 11 based on the earthquake early warning signal can receive the earthquake early warning signal or a ground movement signal (comprising acceleration, speed and displacement caused by the earthquake) measured on site through the Internet, and after judging that the earthquake amplitude reaches a certain degree, the hydraulic servo system 10 is started, the hydraulic oil in the hydraulic telescopic rod 13 is controlled to enable the inner rod 30 of the hydraulic telescopic rod to move in a telescopic manner, the X-direction moving plate 2 and the Y-direction moving plate 3 can deviate from the current balance position, after the three-dimensional vibration isolation support 8 reaches a new balance position, the opening and self-recovery control device 11 based on the earthquake early warning signal transmits current to the electromagnetic valve 17 arranged on a hydraulic loop pipeline, the electromagnet 19 in the electromagnetic valve 17 generates magnetic force to drive the transmission rod 20 to move, the valve body 21 is opened, and the hydraulic oil can flow.

After the earthquake is finished, after a stable power supply is arranged, the hydraulic servo system 10 is started, the hydraulic system working motor 14 is started, the electromagnetic valve 17 on the hydraulic circuit is closed, the electromagnetic valve 17 of the oil outlet circuit is opened to store hydraulic oil into the oil cylinder in the hydraulic guide rod 6, the hydraulic guide rod 6 is restored to be original state to limit the three-dimensional vibration isolation support 8 again, in addition, the oil quantity input into the oil cylinder oil port 25 and the oil cylinder oil port 26 of the lower oil cylinder is controlled by signals (external signals) of a displacement meter arranged on the three-dimensional vibration isolation support 8, so that the three-dimensional vibration isolation support 8 is restored to the original position, then the electromagnetic valve 17 of the oil outlet circuit is closed, the electromagnetic valve is in the normally closed state, and finally the hydraulic telescopic rod 13 is controlled to be recovered and restored.
