Simultaneously, the subassembly 4 that compresses tightly on the procapsid 11 can produce secondary vibration, and the vibration can directly transmit to on the box 1, is provided with damping pad 3 between box 1 and damping core 2, through setting up damping pad 3, can isolated vibration, avoids compressing tightly on the subassembly 4 vibration transmission to damping core 2, avoids then in the vibration transmission to the wall of elevartor shaft, and thus isolated vibration.
When vibration occurs, a part of vibration energy mainly transmitted in a horizontal direction perpendicular to the elevator guide rail is absorbed by the first vibration damping pad 21 and the second vibration damping pad 22, and the other part is absorbed by the third vibration damping pad 23 and the fourth vibration damping pad 24. In addition, the damping core plate 2 is restrained by the damping pads 3 in the front and rear directions, and the damping core plate 2 can be restrained in the left and right directions under the matching of the damping pads 3 and the box body 1, so that the restraining capacity of the damping core plate 2 is improved, the damping core plate 2 is limited to generate large displacement, the damping core plate 2 is prevented from generating rigid collision with the box body 1, and the failure risk is reduced. Meanwhile, the vibration reduction core plate 2 is connected with a wall body of an elevator shaft, and the box body 1 is connected with an elevator guide rail. The secondary vibration generated by the pressing component 4 on the box body 1 can be transmitted to the wall body only through the vibration damping pad 3, and the vibration of multiple sources in multiple directions is absorbed by the vibration damping pad 3.
When assembling the elevator guide rail vibration damping device, the front housing 11 and the rear housing 12 are welded together by the case connection plate 13 to form the case 1. The first, second and third damping core plates 21, 22, 23 are welded together to form the damping core plate 2. Between the damping core 2 and the housing 1, a pre-compressed damping pad 3 is arranged. Finally, the elevator guide rail vibration damping device shown in fig. 1 and 2 is formed, and when the elevator guide rail vibration damping device is installed, the first bent portion 221 and the second bent portion 231 of the second vibration damping core plate 22 and the third vibration damping core plate 23 are connected to the elevator hoistway, and the rear housing 12 of the housing 1 is connected to the elevator guide rail by the connection mechanism. The rear case 12 is connected to the connection mechanism via the first mounting portion 1211 and the second mounting portion 1221 on the third side plate 121 and the fourth side plate 122.
After assembly is completed, the elevator guide rails vibrate when the elevator is running and vibrating. The vibration is transmitted to the rear case 12 by the coupling mechanism, the rear case 12 is welded to the front case 11, and thus the vibration is directly transmitted to the front case 11, and the vibration of the front case 11 is directly transmitted to the hold-down assembly 4. When the vibration amplitude is large and the vibration time is long, secondary vibration can be generated on the compaction component 4. It is therefore necessary to damp not only the vibrations generated by the elevator guide rails, but also the secondary vibrations generated by the hold-down assembly 4. In the embodiment, the box body 1 is connected with the guide rail, the vibration-damping core plate 2 is connected with the elevator shaft, and the vibration-damping pad 3 is arranged between the vibration-damping core plate 2 and the box body 1. The vibration of the elevator guide rail and the vibration of the pressing component 4 can be guided into the wall body after being damped by the damping pad 3, so that the damping capacity of the elevator guide rail damping device is enhanced, and the damping effect is improved.
Example two:
a vibration damping device constructed according to the second embodiment is schematically shown in fig. 9 to 11. For the sake of brevity, the description of the same parts as those of the first embodiment will be omitted when describing the second embodiment.

When the second vibration damping core plate 22 and the third vibration damping core plate 23 are U-shaped members, the vibration damping pads can be prevented from generating relative displacement in the front and back directions, the stability of the vibration damping device for the elevator guide rail is increased, and the failure of the vibration damping device for the elevator guide rail is prevented.
After the second and third vibration damping core plates 22 and 23 are bent to form bent portions parallel to the upper and lower surfaces, the bent portions as in the first embodiment cannot be bent. Therefore, a core plate connecting plate 24 is added in parallel with the front and rear faces, and the core plate connecting plate 24 is welded to the second vibration damping core plate 22 and the third vibration damping core plate 23.
