It will be appreciated that the devices are multifunctional, regardless of their orientation in space.
The embodiment of the invention is applied to the field of seismic isolation and reduction, and the target object 1 to be isolated can be a precise instrument, equipment needing seismic isolation, a working platform, a control room, a safety room and the like. The objects 1 to be isolated are usually sensitive to earthquake and other vibration, and bring immeasurable life and property loss to operators and operation equipment.
The prior art usually adopts rubber shock insulation support, fixes and supports through rubber shock insulation support and treats shock insulation target object 1, can cause the three-dimensional vibrations of horizontal plane and vertical direction when considering that the earthquake takes place, consequently, rubber shock insulation support needs to have three-dimensional shock insulation effect simultaneously concurrently. However, the rubber material is difficult to be made into a material with low horizontal rigidity and high vertical rigidity, and the low rigidity is beneficial to shock insulation, so that the two-dimensional shock insulation effect in the horizontal plane is better, but the shock insulation effect in the vertical direction is slightly poor. Considering that rubber shock insulation support still needs to play the effect of supporting, vertical rigidity can not hang down excessively, consequently vertical direction is difficult to have supporting effect and shock insulation effect concurrently, for the supporting effect who guarantees rubber materials, can only give up the shock insulation effect of vertical direction to a certain extent, in addition the restriction of current rubber production technology, rubber materials's horizontal rigidity also can be great, corresponding horizontal direction's shock insulation effect also can receive great negative effect. That is, the rubber-vibration isolating support needs to use a rubber material having a low horizontal rigidity and a vertical rigidity at least satisfying a supporting effect, but it is difficult to produce such a rubber material with the existing production and manufacturing techniques.
The embodiment of the invention breakthroughs a mechanical structure to achieve the shock insulation effect, and specifically, as shown in fig. 1 to 3, the embodiment of the invention provides an anti-swing shock insulation device, which comprises: the device comprises an installation frame 2, a suspension structure, a swing rod, a hanging basket and a damping unit; the mounting frame 2 is a frame with a circular or regular polygon section; the suspension structure can perform shock insulation in the vertical direction and is fixedly connected with the mounting frame 2; one end of the swing rod is connected with the suspension structure, and the other end of the swing rod is connected with the hanging basket; the damping unit is provided with at least 1 group, and each group comprises at least 3 dampers; one end of the damper is connected with the hanging basket, and the other end of the damper is connected with the inner wall of the mounting rack 2; the hanging basket is used for connecting a target object to be isolated. The suspension structure, namely the swing rod 8 and the hanging basket 9, suspends the target object 1 to be isolated in the mounting frame 2, when vibration in the horizontal direction occurs, the swing rod 8 swings to drive the hanging basket 9 to move relative to the inner wall of the mounting frame 2, and the damper 10 can reduce the displacement of the hanging basket 9 relative to the mounting frame 2, so that the isolation of the horizontal plane is realized. In practical use, the mounting bracket 2 is not limited to a frame with a circular or regular polygon cross section, but may have other shapes, and the cross section of the mounting bracket 2 is preferably circular or regular polygon in consideration of enabling the vibration amplitude and the vibration isolation effect of the object to be isolated in each direction of the horizontal plane to be the same as much as possible.
The embodiment of the invention breaks through the thinking fixed type that the traditional shock isolation device adopts special materials such as rubber and the like, realizes shock isolation by utilizing the mechanical property of the materials, realizes shock isolation by adopting a mechanical structure, and in addition, compared with the shock isolation devices of other mechanical structures, the embodiment of the invention does not need additional energy sources, realizes passive shock isolation by directly combining the swinging of the oscillating bar 8 and the damper 10, and has higher safety and simple and convenient construction.
The suspension structure uses a device capable of vertically isolating, can adopt the existing isolation bearing and also can adopt other structures with vertical isolation functions. In consideration of the limitation of the use of materials such as rubber, the embodiment of the invention also adopts a mechanical structure to realize the vertical shock insulation, and specifically, the suspension structure comprises: spring upper plate 5, isolation spring 6 and spring lower plate 7. The spring upper plate 5 is fixedly connected with the inner wall of the mounting frame 2, so that the object 1 to be isolated can be stably fixed with the mounting frame 2 through the suspension structure. Spring hypoplastron 7 is connected with pendulum rod 8, the both ends of shock insulation spring 6 respectively with spring upper plate 5 and spring hypoplastron 7 fixed connection, spring hypoplastron 7 receives the pulling force that pendulum rod 8 transmitted, can stretch shock insulation spring 6, can remain the parallel for spring upper plate 5 and spring hypoplastron 7 throughout, and then guarantee the shock insulation function of suspended structure's vertical direction, improve the wholeness of motion, shock insulation spring 6 is equipped with 3 at least, obvious shock insulation spring 6 should arrange and form polygonal structure, and not linear arrangement, prevent spring hypoplastron 7 upset. Illustratively, the upper spring plate 5 and the lower spring plate 7 are both circular rings, and 6 shock insulation springs 6 are arranged.
The suspension structure of the invention realizes the shock insulation function in the vertical direction through the shock insulation spring 6, realizes the two-dimensional shock insulation function in the horizontal plane through the combination of the oscillating bar 8 and the damper 10, can realize the three-dimensional space shock insulation function through the combination of the oscillating bar and the damper, has simple structure and high safety, and greatly improves the reliability and durability of the suspension structure.
Considering treating the installation and the shape of shock insulation target object 1, reserving the great space for treating shock insulation target object 1 as far as possible simultaneously under the prerequisite of guaranteeing the shock insulation effect, suspension structure, hanging flower basket 9 all leave the hole, treat that shock insulation target object 1 should leave fixed knot and construct, make the fixed knot who treats shock insulation target object 1 can pass the hole of suspension structure and hanging flower basket 9, guarantee the function of hanging.
In order to further improve the two-dimensional shock insulation effect in the horizontal plane, in the embodiment of the invention, the dampers 10 in the same group are positioned on the same horizontal plane, so that the force generated by the dampers 10 in the same group can be ensured to act on the same horizontal plane, the moment for turning the hanging basket 9 can not be generated, the dampers 10 in the same group are uniformly arranged along the circumferential direction of the inner wall of the mounting frame 2, and the shock insulation effect in each direction in the horizontal plane can be ensured to be the same.
In view of the stability of the basket 9, the basket 9 should be a spatial cylindrical structure, but may be other shapes, and in order to ensure the stability, the basket 9 should at least comprise an upper end surface and a lower end surface. Exemplarily, hanging flower basket 9 includes up end, lower terminal surface and spliced pole, and the up end is the annular with lower terminal surface, and is parallel to each other to connect through a plurality of spliced poles, the spliced pole is evenly set up along 2 inner wall circumference of mounting bracket. In order to improve the seismic isolation effect of the hanging basket 9, in the embodiment of the invention, the dampers 10 are arranged on the upper end surface and the lower end surface of the hanging basket 9, and the specific dampers 10 are provided with 2 groups: one group of dampers 10 are connected with the edge of the upper end face of the hanging basket 9, and the other group of dampers 10 are connected with the edge of the lower end face of the hanging basket 9. Illustratively, each set has 4 dampers 10, and the dampers are evenly arranged along the circumference of the inner wall of the mounting frame 2.
It should be specially noted that, if the cross section of the mounting frame 2 is a regular polygon, the number of sides is N, the shape of the hanging basket is the same as that of the mounting frame 2, the number of the dampers 10 of each group of damping units is an integral multiple of N, and the number of the dampers 10 arranged on each side of the regular polygon is equal. Preferably, one damper 10 is arranged at each fixed point of the regular polygon, the other dampers 10 on each side are uniformly distributed, and the specific number of the dampers 10 can be set according to the required damping size.
In order to further improve the two-dimensional shock insulation effect in the horizontal plane, in the embodiment of the invention, the shock insulation springs 6 are uniformly arranged along the circumferential direction of the inner wall of the mounting frame 2, and when the shock insulation springs are in a free state, the upper spring plate 5 and the lower spring plate 7 are in a horizontal state, so that when the lower spring plate 7 is pulled downwards, the acting force of each spring is the same, the acting force and the acting point in each direction in the horizontal plane are centrosymmetric, and the shock insulation springs 6 can be prevented from being damaged or the lower spring plate 7 can be prevented from overturning due to the moment caused by asymmetry.
Considering that the bearing capacity of a single swing rod 8 is limited, and the object 1 to be isolated by vibration may need to pass through the suspension device and the hanging basket 9, the swing rod 8 is not suitable to be arranged at the axis of the embodiment of the invention, therefore, in the embodiment of the invention, 3 swing rods 8 are arranged along the circumferential direction of the inner wall of the mounting frame 2. The 3 swing rods 8 ensure the stability of the hanging basket 9 and are beneficial to leveling the hanging basket 9 in the installation process; if 2 swing rods 8 are used, it is difficult to enable the hanging basket 9 to be stably suspended; if more than 4 swing rods 8 are used, not only is the leveling difficulty of the hanging basket 9 increased, but also the stress conditions of each swing rod 8 may be different, and the service life of the swing rod 8 with larger stress can be greatly shortened, thereby affecting the safety and stability of the embodiment of the invention. Illustratively, one end of the swing rod 8 is connected with the lower plate 7 of the annular spring, and the other end is connected with the upper end face of the annular hanging basket 9.
Because the oscillating bar 8 and the hanging basket 9 form a structure similar to a simple pendulum when the object 1 to be isolated is subjected to vibration in a horizontal plane, and the oscillation in the horizontal plane is two-dimensional oscillation rather than linear one-dimensional oscillation, in the embodiment of the invention, one end of the oscillating bar 8 is connected with the spring lower plate 7 through a universal hinge, and the other end of the oscillating bar is connected with the hanging basket 9 through a universal hinge. Illustratively, the universal hinge may take the form of a ball hinge or a cross hinge.
In actual shock, the target object 1 to be isolated may generate translational shock or may swing, and particularly, in the case that the target object 1 to be isolated has a fixed structure, in order to prevent the target object 1 to be isolated from swinging, in the embodiment of the present invention, the center of gravity of the target object 1 to be isolated is not higher than the center of the hanging basket 9, and considering the actual installation difficulty, the center of gravity of the target object 1 to be isolated should be slightly lower than the center of the hanging basket 9 or be flush with the center of the hanging basket 9. It should be noted that although the pendulum bar 8 swings like a simple pendulum, the basket 9 moves in a translational manner since the pendulum bar 8 and the basket 3 are both connected to the basket 9.
Before the shock insulation device is actually used, the number of the shock insulation springs 6 and each group of dampers 10 and the length of the oscillating bar 8 can be determined according to actual shock insulation requirements. Different soil, the rock of 2 places of mounting bracket can influence the vibrations cycle when the earthquake produces, the natural cycle when shock isolation device design under the normal conditions should differ great with the vibrations cycle to prevent resonance and then realize the shock insulation, make the natural cycle of shock isolation device obvious be greater than the vibrations cycle during actual design usually, nevertheless too big natural cycle can increase the impact that buffering effect reduces the acceleration, but can increase shock isolation device's vibration amplitude, be unfavorable for the shock insulation equally. The embodiment of the invention comprehensively considers the factors of reducing acceleration impact and vibration amplitude, and the horizontal plane vibration inherent period of the anti-swing shock isolation device is 3-4 s; the natural period of vertical vibration of the anti-swing vibration isolation device is 1.2s-1.5 s. The length of the swing rod 8 can affect the horizontal plane vibration inherent period of the anti-swing shock insulation device, the calculation process can refer to the simple pendulum period, the parameters and the number of the dampers 10 can affect the vibration amplitude in the horizontal plane, the rigidity and the number of the springs can affect the vertical vibration inherent period and the vibration amplitude of the anti-swing shock insulation device, and the calculation process can refer to the period of simple harmonic vibration.
In order to facilitate installation of the embodiment of the invention, the whole of the embodiment of the invention is of a cylinder-like structure, and the suspension structure, the swing rod 8, the hanging basket 9 and the damper 10 of the embodiment of the invention are respectively rotationally symmetrical by taking an axis as a central line. The length mechanical property of each spring is the same, the structure and performance parameters of each damper 10 are the same, and the shape of each oscillating bar 8 is the same, so that the mass production and the manufacturing of each part are facilitated, and the installation of the embodiment of the invention is also facilitated.
In addition, in the embodiment of the invention, the upper spring plate 5 is fixedly connected with the inner wall of the mounting frame 2 through the connecting block 3; the spring upper plate 5 and the inner wall of the mounting rack 2 are connected with the connecting block 3 through bolts 4. The shape of the connecting block 3 is not limited, and the spring upper plate 5 and the mounting frame 2 can be connected at the same time, and for example, an angle iron, a triangular block, a square block and the like can be adopted. In order to fix the embodiment of the invention to the inner wall of the mounting frame 2 conveniently, when the mounting frame 2 is excavated, a threaded hole needs to be reserved in the inner wall of the mounting frame 2 for being in threaded connection with the connecting block 3.
In summary, the embodiment of the invention provides an anti-swing shock isolation device, compared with the prior art, the anti-swing shock isolation device can conveniently adjust the horizontal shock isolation period and the vertical shock isolation period, can realize a very large horizontal shock isolation period by adjusting the length of the swing rod 8, realizes a better horizontal shock isolation effect, and has the characteristics of large shock isolation period, low manufacturing cost, excellent weather resistance, simple structure, safety, reliability and the like.
