For achieving the above object, the utility model provides a kind of combined type vibration damping noise reducer of elevator, this device is by a combined vibration-damping layer, at least one first elastic damping layer and a tie layer are composited, wherein, the combined vibration-damping layer is to be composited by rigid material and flexible material, is used for being connected with elevator main premises face; The described first elastic damping layer is located on the combined vibration-damping layer; Described tie layer is located on the first elastic damping layer, is used for being connected with elevator main.
The combined vibration-damping layer is composited by steel plate and layer of silica gel, and wherein layer of silica gel is compound in the lower surface of steel plate.
The first elastic damping layer is made by rubber material.
Between described combined vibration-damping layer and elastic damping layer, be provided with one second elastic damping layer.
The second elastic damping layer is made by rubber material, and its upper and lower surface is covered with the buffering of rule or irregular alignment and absorbs the spherical or columnar projections of vibration usefulness.
Described tie layer is steel plate or engineering plastics plate.
The first elastic damping layer and second elastic damping are placed in the fixing frame perpendicular to the combined vibration-damping layer, and the lower end of this fixing frame is connected with the combined vibration-damping layer, and the inboard of fixing frame is compounded with vertical vibration damping layer.
Fixing frame is made by steel plate or engineering plastics plate.
Vertical vibration damping layer is made by rubber or plastic material.
Contribution of the present utility model is that it efficiently solves the vibration and noise reducing problem of elevator, and environmental protection is had positive effect.The utility model has improved the bandwidth and the efficient of vibration damping greatly owing to be provided with multistage vibration damping structure, makes the vibration damping frequency band can reach 1HZ～80HZ, and damping rate is greater than 98%.And because vibration damping equipment movement-less part of the present utility model, but member material therefor wear-corrosion resistance, anti-aging, so working life is identical with life of equipment, and need not do special maintenance in the using process.

[embodiment]
The following example is to further explanation of the present utility model and explanation, and the utility model is not constituted any limitation.
In Fig. 1, an embodiment shown in Figure 2, the combined type vibration damping noise reducer 10 of elevator of the present utility model is by a combined vibration-damping layer 1, one first elastic damping layer 2 and a tie layer 3 are compound, formation has the plate-like body of two-stage vibration damping structure, specifically, described combined vibration-damping layer 1 is to be composited by rigid material and flexible material, is used for being connected with elevator main premises face.More particularly, this combined vibration-damping layer 1 is composited by steel plate 1a and layer of silica gel 1b, and wherein layer of silica gel 1b is glued at the lower surface of steel plate 1a, and vibration and noise reducing device when mounted, this layer of silica gel directly fits tightly on elevator main premises face, plays buffering and absorbs the flexible damping effect that vibrates.Place, four angles at steel plate 1a has attachment hole, and steel plate 1a fixes through described attachment hole and elevator main premises face with stone bolt, plays the effect of rigidly fixing.The described first elastic damping layer 2 is located on the combined vibration-damping layer 1, it is bearing main vibration-damping function, specifically, this first elastic damping layer 2 is block bodies of rectangular of being made by rubber material, and its thickness can be determined according to the vibration situation and the designing requirement of elevator main.This first elastic damping layer has enough intensity and elasticity, can cushion and absorb the vibration that elevator main produces.Described tie layer 3 is located on the first elastic damping layer 2, and specifically, this tie layer 3 is made by steel plate or engineering plastics plate, and its adhering junction is used for being connected with elevator main on the first elastic damping layer 2.
For realizing better effectiveness in vibration suppression, in a preferred embodiment shown in Figure 1, between the described combined vibration-damping layer 1 and the first elastic damping layer 2, be provided with one second elastic damping layer 4.Specifically, this second elastic damping layer 4 is made by rubber material, different with the above-mentioned first elastic damping layer 2 is, its thickness is thinner, and as shown in Figure 3, be covered with the columnar projections 4a of rule or irregular alignment in the upper and lower surface of the second elastic damping layer 4, these columnar projections make the vibration that has been weakened by the first elastic damping layer 2 further be cushioned even absorb fully.
Move in the horizontal direction because of vibration in order to limit the above-mentioned first elastic damping layer 2 and the second elastic damping layer 4, they are placed in the fixing frame 5 perpendicular to combined vibration-damping layer 1, specifically, this fixing frame 5 is made by steel plate or engineering plastics plate, and the lower end of this fixing frame is connected with combined vibration-damping layer 1.Be to strengthen effectiveness in vibration suppression, gummed has vertical vibration damping layer 6 in the inboard of fixing frame, and vertical vibration damping layer 6 is made by rubber or plastic material, and it is cushioned the vibration of the substantially horizontal that win elastic damping layer 2 and the second elastic damping layer 4 transmitted and absorbs.
Fig. 4 shows an application example of the combined type vibration damping noise reducer of elevator of the present utility model, among Fig. 4, each has a combined type vibration damping noise reducer 10 with bolt at the two ends, bottom of elevator main seat 7, and 10 steel plate 1a by its combined vibration-damping layer 1 are fixing with stone bolt and elevator main premises face 20 for combined type vibration damping noise reducer.
Consult Fig. 1, Fig. 3 and Fig. 4, when elevator main moves, the vibration that it produced is at first received by the first elastic damping layer 2 and the second elastic damping layer 4, feasible overwhelming majority vibration is cushioned and absorbs, and the vibration that arrives combined vibration-damping layer 1 is very little, and because the damping effect of the layer of silica gel 1b of combined vibration-damping layer 1, make the vibration of elevator main be absorbed fully and eliminate by vibration and noise reducing device of the present utility model, and friction is delivered to elevator main premises face and elevator outside, thereby has blocked the propagation path of noise and vibration fully.
