Problems solved by technology

However, doing so will cause the traction machine to easily overturn
[0005] In addition, for the above two methods, due to the adoption of two-level anti-vibration, the system will change from one natural frequency to two natural frequencies. If the two natural frequencies of the system are consistent with the vibration frequency of the traction machine, then Resonance will occur, which will amplify the vibration of the traction machine and the vibration transmitted to the building will also increase

Embodiment 1

[0051] The present invention provides an elevator device for suppressing the vibration of the traction machine. The elevator device comprises a hoistway 1, an elevator car 2, a counterweight 3, a steel wire rope 4, a traction machine 5, and a base 6 fixed at the lower end of the traction machine 5. 1. The load-bearing beam 8 fixed between the building walls 7 at both ends and at least one anti-vibration device 9 fixed between the base 6 and the load-bearing beam 8 are used to suppress the vibration of the traction machine 5. It is characterized in that the anti-vibration Vibration device 9 comprises:

[0052] An upper elastic layer 90, the upper elastic layer 90 includes:

[0053] A first upper plate 900, the center of the first upper plate 900 is fixedly connected to the base 6 by bolts;

[0054] A first elastic body 901, the first elastic body 901 is fixed on the lower end of the first upper plate 900;

[0055] An intermediate quality layer 91, the intermediate quality layer...

Embodiment 2

[0074] In this embodiment, on the basis of the first embodiment above, the upper elastic layer 90, the middle mass layer 91 and the lower elastic layer 92 are split, and the upper elastic layer 90 also includes a second lower plate 902 fixed on the first elastic The lower end of the body 901 is used to connect the first elastic body 901 and the first mass body 910;

[0075] The lower elastic layer 92 also includes a second upper plate 922 fixed on the lower end of the first mass body 910 for connecting the first mass body 910 with the second elastic body 920 .

[0076] The second upper plate 922 includes a second internal thread seat 9220 for fastening the second upper plate 922 and the first mass body 910 with bolts.

[0077] Specifically, such as Figure 5 As shown, the upper elastic layer 90, the middle mass layer 91 and the lower elastic layer 92 are split, and the upper elastic layer 90 also includes a second lower plate 902, which is fixed to the lower end of the first ...

Embodiment 3

[0081] In this embodiment, on the basis of the first embodiment above, the upper elastic layer 90, the middle mass layer 91, and the lower elastic layer 92 are integrated, and the first elastic body 901 is preliminarily combined with the first mass body by casting or bonding. The upper end of the mass body 910 is fastened, and the second elastic body 920 is pre-fastened to the lower end of the first mass body 910 by casting or bonding.

[0082] Specifically, such as Figure 6 As shown, the difference between the third embodiment and the second embodiment above is that the upper elastic layer 90, the middle mass layer 91 and the lower elastic layer 92 are integrated, that is, the second lower part of the upper elastic layer 90 in the second embodiment above The plate 902 and the second upper plate 922 in the lower elastic layer 92 can be removed, and the first elastic body 901 and the first mass body 910 can be fastened in advance and the first mass body 910 can be connected to...

Abstract

The invention relates to the elevator technology field, in particular to an elevator device for restraining vibration of a tractor and an elevator. The elevator device for restraining the vibration ofthe tractor comprises a shaft way, an elevator compartment, a counter weight, a steel wire rope, the tractor, a bottom seat, a bearing beam and an anti-vibration device, wherein the anti-vibration device comprises an upper elastic layer which comprises a first upper plate fixedly connected with the bottom seat and a first elastic body fixed at the lower end of the first upper plate, a middle masslayer which comprises a first mass body fixed at lower end of the upper elastic layer and at least one second mass body fixed on one side of the first mass body through a bolt, and a lower elastic layer which comprises a second elastic body fixed at the lower end of the first mass body and a first lower plate fixed at the lower end of the second elastic body and fixed together with the bearing beam. The elevator device for restraining the vibration of the tractor has the beneficial effects of being capable of effectively restraining the vibration of the tractor, effectively adjusting intrinsic frequency of a system, preventing resonance from occurring, and being capable of preventing the toppling risk from occurring.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator device and an elevator for suppressing the vibration of a traction machine. Background technique [0002] Normally, the anti-vibration device installed between the elevator traction machine and the building can suppress the vibration transmitted from the traction machine to the building. However, in recent years, due to the high speed of elevators, especially the speed of elevators in high-rise residential buildings with high noise requirements, the requirements for the vibration suppression efficiency of elevators are also getting higher and higher. [0003] In the prior art, both ends of the load-bearing beam are directly fixed to the building. For example, the two ends of the load-bearing beam are embedded in the building wall, which is equivalent to being integrated with the building. The anti-vibration device is installed between the base of the traction machin...
