It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example (b): a special speed elevator tows amortization vibration isolation device, combines to show in figure 1 and figure 2, including spandrel girder shock attenuation frame 1, bearing girder 2, host computer chassis 3 and host computer roof-rack 4, spandrel girder shock attenuation frame 1, bearing girder 2, host computer chassis 3 and host computer roof-rack 4 from the bottom up arrange in proper order. The top of the main machine top frame 4 is fixed with a traction machine 41 through a bolt, the traction machine 41 mainly functions to provide power required by the movement of the elevator car, the traction machine 41 is generally called a main machine in the industry, and the subsequent main machines are all called traction machines 41.

As shown in fig. 2, the main frame 3 and the main frame top frame 4 are combined together to stably and firmly support the elevator car, a polyurethane damping plate 31 is arranged between the main frame 3 and the main frame top frame 4, the polyurethane damping plate 31 has good damping and buffering performance, and when the elevator car is used, the polyurethane damping plate 31 can absorb part of the vibration energy of the main frame moving at high speed as a first-stage damping structure, so that the vibration frequency is reduced.

As shown in fig. 2, a plurality of host shock-absorbing pads 21 are arranged between the main bearing beam 2 and the host underframe 3, the host shock-absorbing pads 21 are fixedly connected with the host shock-absorbing pads and the host underframe 3 through bolts, rubber is preferably selected as a main material for the host shock-absorbing pads 21, and different materials can be selected according to actual needs. The host damping pad 21 is used as a secondary damping structure to secondarily absorb part of the host operation vibration energy. The hardness of the host damping pad 21 is different from that of the polyurethane damping plate 31, and the absorption vibration frequency of the host damping pad and the polyurethane damping plate is different, so that the damping effect is further enhanced.

Referring to fig. 1 and 2, the load-bearing beam shock absorption frame 1 comprises an upper layer steel 11, a shock absorption rubber plate 13 and a lower layer steel 12, and the structures are arranged layer by layer from top to bottom. The upper layer steel 11 and the lower layer steel 12 are both H-shaped steel. The stiffness of the damping rubber plate 13 is similar to that of the main unit damping pad 21 and the polyurethane damping plate 31, and is also for absorbing vibration of different frequencies.
