In this embodiment, a vibration damping unit is disposed between each core board and the corresponding baffle. Thus, when the elevator guide rail vibrates, the core plate can respectively act with the corresponding vibration reduction units along three directions, namely, the vibration reduction bracket can absorb vibration energy along three directions. In the process of vibration, dislocation of the core plate assembly 2 relative to the vibration reduction unit can be effectively prevented, stable vibration reduction effect is maintained, and meanwhile rigid collision between the core plate assembly 2 and the main shell 1 is avoided. The mounting plate 3 in this embodiment is provided on the core plate outside the receiving chamber, and when assembled, the mounting plate 3 is for mounting to the elevator guide rail and the main housing 1 is for mounting to the elevator hoistway wall. In other embodiments, the mounting plate 3 may be attached to the hoistway wall, and the main casing 1 may be attached to the elevator rail.

In the present embodiment, the damper unit is a damper block 4 made of rubber, and it is understood that in other embodiments, a damper block 4 made of a polymer elastic material may be used, or an elastic body such as a spring may be used as the damper unit.

The accommodating cavity surrounded by the three baffle plates has a first port and a second port, and two ends of the core plate assembly 2 in this embodiment extend out of the accommodating cavity from the first port and the second port respectively, for convenience of description, the three core plates in this embodiment are the first core plate 20, the second core plate 21 and the third core plate 22 respectively, specifically, two ends of the first core plate 20 and the second core plate 21 extend out of the accommodating cavity, that is, the length dimensions of the first core plate 20 and the second core plate 21 are larger than those of the third core plate 22. Mounting plates 3 are provided at both ends of the core assembly 2 extending out of the accommodation chamber, and in this embodiment, the mounting plates 3 are welded to the first core plate 20 and the second core plate 21. In addition, the barrier is provided with a mounting wall 15, and for convenience of description, the barrier in this embodiment includes a first barrier 10, a second barrier 11, and a third barrier 12, and the mounting wall 15 is formed by extending both ends of the third barrier 12 outwardly.

Vibration energy can be absorbed in two directions through the auxiliary vibration reduction block 40, and the vibration reduction effect is improved. It will be appreciated that in other embodiments, the secondary core 23 may be provided at only one end of the core assembly 2, and correspondingly, the secondary baffle 13 and secondary damper blocks 40 may be provided at only one end. In this embodiment, in order to provide the auxiliary core plate 23, the length of the third core plate 22 is designed to be smaller than the first core plate 20 and the second core plate 21, so that a space is reserved for installing the auxiliary core plate 23. It will be appreciated that in other embodiments, the auxiliary core plates 23 may not be provided, and that correspondingly, three core plates may be designed to be of equal length.

Good damping effect is obtained by bringing the damper mass 4 to a suitable degree of compression because the displacement of the core plate is small when vibration occurs, the compression of the damper mass 4 by the displacement of the core plate is also small, the vibration energy absorbed by the degree of compression is small when the damper mass 4 is in a natural state and is not compressed, and when the damper mass 4 is in an excessively compressed state, a situation similar to that of a rigid contact occurs between the core plate and the damper mass 4 (i.e., the damper mass 4 is excessively compressed to cause its rigidity to become large) is obtained. Therefore, in order to obtain a good vibration reduction effect, the vibration reduction block 4 needs to be compressed in advance, and in this embodiment, the following manner is adopted: the first baffle 10 and the second baffle 11 are respectively provided with a jacking component 5, the jacking components 5 comprise an adjusting bolt 50 and a pressing plate 51, the jacking components 5 arranged on the first baffle 10 are taken as an example, the adjusting bolt 50 is connected to the first baffle 10 in a threaded manner, the pressing plate 51 is arranged between the first baffle 10 and the corresponding vibration reduction block 4, and the end part of the adjusting bolt 50 is movably propped against the pressing plate 51.

It will be appreciated that in other embodiments, the pressing assembly 5 may be disposed on only one baffle, and since the three core plates are integral, when the pressing plate 51 on one side applies a pressing force to the damper block 4, the pressing force may be conducted to the other two core plates through the damper block 4 and the corresponding core plates, so that a certain pressing force is applied to the other two damper blocks 4 to achieve precompression.

As described above, the damper block 4 provided in correspondence with the third barrier 12 may be pre-compressed by a predetermined amount by the biasing force of the biasing members 5 provided in the first barrier 10 and the second barrier 11. However, in order to directly precompress the damper block 4 disposed corresponding to the third baffle 12, the distance between the third baffle 12 and the third core plate 22 is controlled in the present embodiment so that the distance therebetween is smaller than the natural thickness H of the damper block 4 and larger than the limit compression thickness Hmin of the damper block 4. Specifically, in this embodiment, the limiting plates 16 are disposed between the third baffle 12 and the first baffle 10 and between the third baffle 12 and the second baffle 11, and the spacing between the third baffle 12 and the third core plate 22 is limited to L by the limiting plates 16, hmin < L < H, so that the third baffle 12 can precompress the damper blocks 4 disposed corresponding thereto, and the precompression degree can be controlled by controlling the size of the limiting plates 16.

Therefore, in the present embodiment, the vibration damper 4 is precompressed by the structure of the pressing assembly 5 and the stopper plate 16, but in other embodiments, only one of the vibration damper 4 may be selected to be precompressed.

In addition, in the present embodiment, the limiting plates 16 are disposed on the first baffle 10 and the second baffle 11, respectively, and it is understood that in other embodiments, the limiting plates 16 may be disposed on the third baffle 12. Alternatively, the limiting plate 16 may also include a first limiting plate and a second limiting plate. Thus, the first baffle plate 10 and the second baffle plate 11 are respectively provided with a first limiting plate, the third baffle plate 12 is provided with a second limiting plate matched with the first limiting plate, and the end faces of the first limiting plate and the second limiting plate are attached and fixedly installed. The limitation of the space between the third barrier 12 and the third core plate 22 can be achieved by presetting the dimensions of the first and second limiting plates.

In order to avoid interference between the auxiliary baffle 13 and the auxiliary core plate 23, the first core plate 20 and the second core plate 21 may be first moved close to the first baffle 10 and the second baffle 11 respectively to be placed in the accommodating cavity, and then the whole is moved so that the third core plate 22 is pressed against the corresponding vibration-damping block 4.
