Abstract
The utility model discloses a vibration isolating and reducing structure for lift main machines, which comprises a main machine, a motor base, a machine frame beam, a support leg and vibration isolating rubber, wherein the main machine is arranged on the motor base; the main machine and the motor base are integrally fixed on the machine frame beam arranged on the support leg; the vibration isolating rubber is provided with at least two stories. The utility model adopts the double-layer vibration isolating rubber to ensure the use rigidity of each layer of rubber and decrease the elasticity coefficient of the vibration isolating rubber of a main machine system of the whole lift so that the low frequency vibration produced by the lift main machines are effectively isolated and removed; besides, the double-layer vibration isolating rubber is smartly arranged between the same mounting lay, or is respectively arranged between different mounting lays, such as between the lift main machine and the motor base, the motor base and the machine frame beam, the machine frame beam and the support leg, or the support leg and the ground.
Description
Technical field
The utility model relates to a kind of vibration damping and vibration isolation structure of elevator main.
Background technology
In the existing elevator device, in order to reduce the influence of elevator main vibration to building, the general one deck rubber that adopts in its main frame bottom carries out vibration damping.For the permagnetic synchronous motor main frame, its vibration source frequency concentrates on low frequency part (3～4Hz), if this low-frequency component is realized good vibration isolating effect, the just essential lower vibration isolation rubber of elasticity modulus K that adopts, but, the rigidity of vibration isolation rubber and its elasticity modulus K are proportional, and the K value is more little, and rigidity is just more little.On the other hand, elevator device requires the main frame vibration isolation rubber to have higher rigidity, is enough to bear the weight of elevator device, is unlikely to again because of weight deformation to take place.And the single-layer partiting polarization rubber that existing elevator main is adopted, under the situation that guarantees its rigidity, the effectiveness in vibration suppression of the low-frequency vibration that main frame is produced is not good.
Summary of the invention
The purpose of this utility model is to provide a kind of both can carry out vibration damping to the low-frequency vibration of elevator main, can guarantee that again vibration isolation rubber has the vibration damping and vibration isolation structure of higher stiffness.
The technical scheme that the utility model adopted: a kind of vibration damping and vibration isolation structure of elevator main, comprise main frame, motor base, frame machine beam, spike and vibration isolation rubber, main frame is installed on the motor base, and one is fixed on the frame machine beam, frame machine beam places on the spike, it is characterized in that described vibration isolation rubber is two-layer at least.
Above-mentioned two-layer vibration isolation rubber is arranged between the same installation aspect.
Above-mentioned two-layer vibration isolation rubber is arranged at respectively between the different installation aspects, and one deck of vibration isolation rubber is arranged between motor base and the frame machine beam, and another layer is arranged between frame machine beam and the spike.Can arrange like this that also one deck of vibration isolation rubber is arranged between elevator main and the motor base, another layer is arranged between motor base and the frame machine beam.Can also arrange that like this one deck of vibration isolation rubber is arranged between elevator main and the motor base, another layer is arranged between frame machine beam and the spike.
The beneficial effects of the utility model, (1) adopt double-layer vibration isolating rubber, both can guarantee the use rigidity of every layer of rubber, can reduce the elasticity modulus of vibration isolation rubber in the whole elevator main system again greatly, thereby effectively exclude the low-frequency vibration that elevator main produces; (2) above-mentioned double-layer vibration isolating rubber can be arranged between the same installation aspect neatly, perhaps be arranged between the different installation aspects, between elevator main and motor base, between motor base and the frame machine beam, between frame machine beam and the spike, or between spike and the ground.
Description of drawings
Fig. 1 is the first example structure scheme drawing of the present utility model;
Fig. 2 is the second example structure scheme drawing of the present utility model.
The specific embodiment
The vibration damping and vibration isolation structure of elevator main described in the utility model comprises main frame 1, motor base 2, frame machine beam 3, spike 4 and vibration isolation rubber 5, wherein, main frame 1 is installed on the motor base 2, and one is fixed on the frame machine beam 3, and frame machine beam 3 places on the spike 4, and described vibration isolation rubber 5 is two-layer at least.
Above-mentioned vibration isolation rubber 5 can stackedly be arranged between the same installation aspect, between main frame 1 and motor base 2, and between motor base 2 and the frame machine beam 3, between frame machine beam 3 and the spike 4, or between spike 4 and the ground.Though this arrangement can realize excluding the low-frequency vibration of elevator main, but, consider that vibration isolation rubber 5 has certain thickness, place same installation aspect if two-layer or multilayer vibration isolation rubber is stacked, may cause main frame in operational process, to produce and rock, so its implementation result is not the best.
In order to reach optimum efficiency, above-mentioned vibration isolation rubber 5 can be arranged at respectively between the different installation aspects, and this installation aspect can be between main frame 1 and the motor base 2, between motor base 2 and the frame machine beam 3, between frame machine beam 3 and the spike 4, or between spike 4 and the ground.
Below introduce the two kinds of vibration isolation rubber arrangements that can realize best vibration isolating effect:
Embodiment one
As shown in Figure 1, vibration isolation rubber 5 is divided into two-layer, and wherein one deck is arranged between motor base 2 and the frame machine beam 3, and another layer is arranged between frame machine beam 3 and the spike 4.
Embodiment two
As shown in Figure 2, vibration isolation rubber 5 is divided into two-layer, and wherein one deck is arranged between elevator main 1 and the motor base 2, and another layer is arranged between motor base 2 and the frame machine beam 3.
Except that above-mentioned two kinds of arrangements, vibration isolation rubber 5 can also arrange that so wherein one deck is arranged between elevator main 1 and the motor base 2, and another layer is arranged between frame machine beam 3 and the spike 4.In addition, between spike 4 and ground, also one deck vibration isolation rubber can be set.
In addition, vibration isolation rubber 5 can also divide three layers, is arranged at respectively between elevator main 1 and the motor base 2, between motor base 2 and the frame machine beam 3, between frame machine beam 3 and the spike 4.
In the vibration damping and vibration isolation structure described in the utility model, every layer of vibration isolation rubber all has higher rigidity, and for whole elevator main system, the elasticity modulus K value of its vibration isolation rubber reduces greatly than individual layer rubber, therefore, can effectively exclude the low-frequency vibration that elevator main produces.
