Abstract
The utility model provides a vibration-damping and noise-reduction device used for an elevator drag machine, relating to the vibration-damping and noise-reduction technical field, which comprises a composite vibration damping part, an inertia block and a balance adjustment part; a groove is arranged on one side of the inertia block; the composite vibration-damping part is arranged inside the groove; the balance adjustment part goes through and joins the inertia block and composite vibration damping part. The utility model utilizes various elastic materials to absorb and obstruct vibration; a balance adjustment system is also provided to fully absorb and obstruct the vibration and thus the noise is maximally reduced.
Description
Technical field
The utility model relates to vibration and noise reducing device, relates in particular to a kind of vibration and noise reducing device that is used for elevator traction machine.
Background technology
Elevator traction machine is arranged at the top or the bottom of elevator usually, and with the going up or down, produce vibration in elevator elevator traction chance in service of towed elevator car, in the stop process especially halfway, this vibration can produce noise, causes the discomfort to surrounding population.Especially in some Architectural Equipments, the people lives or the room and the elevator hoistways of office are total under the situation of wall, and this class vibration is not wished to take place.If the natural frequency of vibrative frequency and building is close, form resonance, with producing bigger noise, form environmental pollution.For addressing the above problem, Granted publication has been number for CN2846375Y discloses a kind of machine beam vibration damping and vibration isolation device of putting, and only adopts the vibration-proof rubber packing ring to absorb and intercepts vibration, and its effect is not ideal enough.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of respond well vibration and noise reducing device that is used for elevator traction machine is provided.
The technical scheme that realizes above purpose is:
A kind of vibration and noise reducing device that is used for elevator traction machine comprises combined vibration-damping parts, inert block and balance adjusting portion part; Described inert block simultaneously is provided with groove; Described combined vibration-damping parts are arranged in this groove; Described balance adjustment parts pass described inert block and the combined vibration-damping parts link together both.
In a kind of optimized technical scheme, described combined vibration-damping parts are made by the elastomeric material of the different Hooke coefficients of multilayer, layer with layer between be connected by rigidity or elastic plate.
In a kind of optimized technical scheme, described balance adjustment parts are adjustable bolt, and its top is provided with a plurality of nuts, is provided with spring washer between nut.
Because adopt above structure, the utility model adopts multiple elastomeric material to absorb and intercepts vibration, and is provided with balance-conditioning system, vibration is fully absorbed and intercept, thereby noise is lowered largely.
Description of drawings
Fig. 1 is the scheme of installation according to the vibration and noise reducing device of the utility model preferred embodiment.
Fig. 2 is the installation enlarged drawing of adjustable bolt among Fig. 1.
Fig. 3 is the scheme drawing according to the combined vibration-damping parts of the utility model preferred embodiment.
Fig. 4 is the scheme drawing according to the inert block of the utility model preferred embodiment.
The specific embodiment
With reference to figure 1 and Fig. 2, a kind of vibration and noise reducing device comprises combined vibration-damping parts 10, inert block 20 and four adjustable bolts 30.Inert block 20 is arranged at combined vibration-damping parts 10 upper ends, and the two is by four adjustable bolt 30 captive joints.Whole vibration and noise reducing device is installed on two I-beam sections 40 that are fixed in abreast on the building body 50.Elevator traction machine 60 is positioned over the top of inert block 20, is in the zone that four adjustable bolts 30 are surrounded.
Four adjustable bolts 30 are arranged at four jiaos of vibration and noise reducing device respectively, and it comprises screw rod 31, nut 35, two nuts 32 and 34 and spring washer 33.Nut 35, two nuts 32 and 34 and spring washer 33 be positioned at the homonymy of inert block 20, spring washer 33 is arranged between two nuts 32 and 34.
With reference to figure 3, combined vibration-damping parts 10 profiles are cuboid, and it is composited by five layers of different elastomeric material of Hooke coefficient, are connected to each other by rigidity or elastic plate between layer and the layer.Four jiaos of fixed orifices 11 that are respectively equipped with adjustable bolt 30 of combined vibration-damping parts 10.Elastomeric material can use as elastic caoutchouc, polyether polyols with reduced unsaturation etc.
With reference to figure 4, the profile of inert block 20 is a cuboid, is provided with the groove 21 that the cross section is a rectangle on its one side.The size of groove 21 and combined vibration-damping parts 10 couplings can fasten on the combined vibration-damping parts 10 inert block 20, and both closely cooperate.Four jiaos of fixed orifices 211 that are respectively equipped with adjustable bolt 30 at bottom portion of groove.Inert block 20 can be made by cement steel or cast iron.
More than by fact Example utility model is specifically described, but embodiment does not constitute any restriction of the present utility model.Any change in the claim scope all is subjected to protection of the present utility model.
