It should be noted that the illustration and description of components and processes known to those of ordinary skill in the art, which are not relevant to the present utility model, have been omitted for clarity. All other embodiments, which can be made by a person skilled in the art based on the embodiments of the utility model without any inventive effort, are intended to fall within the scope of the utility model.
The utility model is further described below with reference to the accompanying drawings: a three-dimensional shock isolation system with self-resetting and self-balancing functions comprises an upper horizontal shock isolation system and a lower vertical shock isolation system. The upper horizontal shock isolation system comprises a horizontal top plate 1, a connecting plate 2 and a horizontal bottom plate 3. The lower vertical shock isolation system comprises a vertical guided roof 10 and a vertical guided floor 11. The upper horizontal shock isolation system and the lower vertical shock isolation system are fixed through 4 positioning bolts, so that the shock isolation system can realize three-dimensional shock isolation, as shown in fig. 1.
As shown in fig. 2 to 4: the upper horizontal shock isolation system of the shock isolation system firstly embeds two first sliding blocks 5 into two first linear guide rails 4, further fixes the two first linear guide rails 4 inside the horizontal top plate 1 along the X direction through four bolts by using the customized horizontal top plate 1 with 8 retainers, and further connects the customized connecting plate 4 with the two first sliding blocks 5 through bolts by using reserved threaded holes. Then the two second sliding blocks 7 are firstly embedded into the two second linear guide rails 6, the customized horizontal bottom plate 6 with 8 retainers is further fixed inside the horizontal bottom plate 3 along the Y direction through four bolts, and the customized connecting plate 2 with reserved threaded holes is further connected with the two second sliding blocks 7 through bolts. The horizontal top plate 1 and the horizontal bottom plate 3 can be connected together through the inner components to provide certain vertical rigidity for the upper horizontal shock isolation system, and finally 8 pre-tensioned spring ropes 9 are fixed through the retainers on the horizontal top plate 1 and the horizontal bottom plate 3. The restoring force of the abutment is provided by the pretension of the spring cord 9 to extend and retract.
When an earthquake occurs, horizontal vibration in earthquake waves can be coupled through movement in two directions, the horizontal top plate 1 and upper equipment can move relative to the horizontal bottom plate 3 in any direction of a horizontal plane, self-resetting of an upper horizontal vibration isolation system is realized through pre-tensioning the spring ropes 9, and meanwhile, vibration acceleration of the upper equipment is far smaller than ground vibration acceleration, so that the vibration isolation effect is achieved.
As shown in fig. 5 to 7: the lower vertical shock isolation system of the shock isolation system is characterized in that 8 angle steels 14 are fixed on a vertical guide rod top plate 10 and a vertical guide rod bottom plate 11 through bolts, 9 vertical springs 10 are further sleeved on a hollow guide rod of the vertical guide rod bottom plate 12, and the inner diameter of each vertical spring 10 is 5mm larger than the outer diameter of the guide rod of the vertical guide rod bottom plate 12.

The 4 damping guide rails 11 are further connected with the vertical guide rod top plate 7 and the vertical guide rod bottom plate 12 through angle steel 8, so that the vertical shock isolation system is prevented from swinging. The bolt guide 9 is further passed through the vertical belt guide top plate 7 and the vertical belt guide bottom plate 12 to apply a pre-compression force to the vertical shock isolation system.
When the vertical top plate 7 with guide rod is subjected to vibration transferred by the upper structure, the vertical top plate 7 with guide rod compresses the vertical spring 13, and the vertical spring 13 moves up and down along the guide rod 12, so that vibration in the vertical direction is weakened and absorbed. In the implementation process, a layer of lubricating oil is generally smeared on the outer wall of the guide rod 12, so that the vertical spring 13 is prevented from generating larger friction heat with the outer wall of the guide rod 12 when being compressed. Meanwhile, the vertical springs 13 are pre-compacted according to requirements, so that self-balancing of the lower vertical shock insulation support is realized.
The upper horizontal shock isolation system is fixedly connected to the lower vertical shock isolation system through bolts, the upper horizontal shock isolation system is used for absorbing and weakening vibration in the horizontal direction, and the lower vertical shock isolation system is used for absorbing and weakening vibration in the vertical direction, so that the self-resetting and self-balancing equipment three-dimensional shock isolation system is realized.
