Detailed Description
For ease of understanding, the specific structure and operation of the present invention will be further described herein with reference to FIGS. 1-6:
unlike the traditional passive vibration isolating support, the invention has the active control function, and can adjust the damping and rigidity of the vibration isolating support in real time through the controller, thereby realizing the damping and control of vibration, and having good integrity, high stability, simple manufacturing process and convenient installation and operation.
In order to achieve the above object, the present invention provides the following specific embodiments:
as shown in fig. 1-3, the embodiment of the invention includes a first energy consumption part a connected with each other and offset by 90 degrees, a second energy consumption part B located above the first energy consumption part a, and a third energy consumption part C disposed above the second energy consumption part B. In operation, as shown in fig. 3, the bottom surface of the first energy dissipation portion a is fixed on the lower structure, and the top of the third energy dissipation portion C is fixed on the upper structure, thereby forming a supporting structure.
When designing, the first energy consumption part A and the second energy consumption part B are identical in structure and are different from each other only by 90 degrees. More specifically: as shown in fig. 3 to 4, each of the first energy consumption portion a and the second energy consumption portion B is composed of an upper support plate 10, a lower support plate 20, an arcuate bevel gear 22, a rotating shaft 31, a semicircular buckle 34, a buckle base 33, a limit protrusion 12, a motor as a driving power source 32, and the like. In actual assembly, as shown in fig. 5, the arcuate bevel gear 22 is located at the groove bottom of the groove-plate-shaped upper support plate 10, and the arcuate bevel gear 22 and the groove bottom of the upper support plate 10 are integrally connected by welding. The buckle base 33 is positioned at the bottom of the groove plate-shaped lower support plate 20, and the buckle base 33 and the lower support plate 20 are connected into a whole through welding; meanwhile, a bearing-seat-like arrangement is formed between the semicircular buckle 34 and the buckle base 33, so that the rotating shaft 31 is mounted at the lower seat plate 20 as shown in fig. 4. In addition, a motor is arranged on a sealing plate at the notch of the lower support plate 20, and the lower support plate 20 is connected with the motor through bolts; after that, the motor is connected with the rotating shaft 31, and the middle section of the rotating shaft 31 is provided with a bevel gear section 35.
When installed, the upper and lower seat plates 10, 20 are shown with opposite notches as shown in figures 1-3. The two groove walls of the upper seat plate 10 protrude downward and snap inwardly to form a mating end 21 with an inner flange 21a, and the two groove walls of the lower seat plate 20 are recessed and turned outwardly to form an arcuate guide surface 11 with an outer flange 11 a. The relative sliding function of the upper and lower seat plates 10 and 20 is achieved by the snap and sliding engagement of the engagement end 21 shown in fig. 5 with the arcuate guide surface 11 shown in fig. 4. At the same time, the arcuate bevel gear 22 and the bevel gear segment 35 intermesh to provide a source of power for either active or passive relative sliding movement of the upper and lower support plates 10, 20.
When the upper support plate 10 and the lower support plate 20 slide passively, namely, when the invention is in a passive control state, the power reaction of the support structure is smaller, and the relative sliding of the support plates at the first energy consumption part A and the second energy consumption part B can drive the rotating shaft 31 to act and cut magnetic force lines at the motor; by using the principle of magnetic electricity generation, the motor can convert mechanical energy generated by external load into electric energy and store the electric energy in a battery of the electricity storage component for providing working power for a subsequent active control mode.
Of course, in order to improve the operational reliability of the present invention, as shown in fig. 3 to 4, both ends of the groove wall of the lower support plate 20 are provided with a limiting protrusion 12 for limiting the maximum relative displacement of the upper support plate 10 and the lower support plate 20.
On the basis of the above structure, as shown in fig. 1-2 and fig. 6, the third energy dissipation part C of the present invention is a spherical hinge structure, and includes a spherical hinge housing 41, a high-temperature vulcanized rubber body 45, a spherical polytetrafluoroethylene plate 44, and a ball head 42 connected with a steel column or a connecting rod 43. When assembled, the spherical hinge housing 41 is bottomless and is positioned above the second energy dissipation part B, and the spherical hinge housing 41 and the second energy dissipation part B are connected by welding. As shown in fig. 6, the ball head 42 is located inside the spherical hinge housing 41, and a spherical polytetrafluoroethylene plate 44 and a high-temperature vulcanized rubber body 45 are sequentially arranged between the spherical hinge housing 41 and the ball head 42, and a steel wire mesh is embedded in the high-temperature vulcanized rubber body 45.
The third energy consumption part C can keep the bottom and upper structures of the invention as parallel or at a specific angle as possible after assembly and during operation, prevent the stress concentration phenomenon at the position of the invention and achieve the vibration isolation effect. Meanwhile, the high temperature vulcanized rubber body 45 provided in the third energy consuming part C of the present invention is also aimed at consuming vertical load by deformation of the high temperature vulcanized rubber body 45. The first energy consumption part A and the second energy consumption part B are arranged in a crossing way, so that horizontal load from any direction can be offset, and then the three-level energy consumption assembly is formed by matching with the high-temperature vulcanized rubber body 45 of the spherical hinge structure, so that the three-way earthquake-resistant energy-saving device has the characteristic of three-way earthquake resistance.
Further, the present invention may also employ a distributed control mode, i.e., each semi-active seismic isolation bearing is equipped with a controller that communicates over a network, such as an ethernet, wireless network, etc. Thus, the acquisition sensor equipped with each semi-active shock insulation support can determine how the semi-active shock insulation support should actively move according to the position of the semi-active shock insulation support and the states of surrounding supports. The method has the advantages that the method can realize highly distributed control without a centralized controller, thereby improving the reliability and the robustness of the system and being very flexible and convenient to use.
The overall advantages of the invention thus far are as follows:
1) When the whole structure bears a small horizontal load, the moving directions of the first energy consumption part A and the second energy consumption part B are mutually perpendicular; according to the plane vector, the invention can move in any direction in the realization plane, and kinetic energy can be converted into potential energy through the height difference between the first energy consumption part A and the second energy consumption part B during movement, so that the purposes of passive damping and passive control are achieved.
2) When the whole structure bears a large horizontal load, the motor adopts different operation conditions according to the application and the vibration isolation requirement of the invention.
Working condition one: the problem of the excessive displacement of superstructure is solved, but the motor operation of the great regional motor of independent control displacement to external load direction reduces superstructure displacement this moment.
Working condition II: the resonance problem is solved, the motor is controlled to apply power to the opposite direction with the rotation trend, the rigidity and the damping of the invention are changed, and the resonance characteristic of the structure is further changed.
And (3) working condition III: the problem of the uneven atress of superstructure or jolt from top to bottom is solved, and the synchronous operation of motor of all first power consumption portion A of control this moment, the synchronous operation of motor of all second power consumption portion B can guarantee through this kind of mode that the relative displacement at all support tops, namely the top of connecting rod 43 is zero to make the superstructure reach the effect of vibration isolation.
3) The high temperature vulcanized rubber body 45 in the spherical hinge structure of the present invention can absorb and dissipate a part of the vertical impact by shear deformation when the entire structure is subjected to the vertical load. Meanwhile, the working states of the first energy consumption part A and the second energy consumption part B can change the load direction and do hysteresis motion to a specific direction so as to consume energy, so that the invention can have good shock insulation effect in the vertical direction.
