Abstract
The utility model relates to the technical field of vibration and noise reduction. The utility model provides a dismountable elevator vibration and noise reduction device which includes two groups of compound vibration reduction parts, inerted blocks and balance adjusting parts that are arranged symmetrically; one surface of the inerted block is provided with a groove; the compound vibration reduction part is arranged in the groove; the balance adjusting parts pass through the inerted block and the compound vibration reduction part to connect with the two together; the two inerted blocks are connected through a connector. The utility model adopts multi-elasticity materials to absorb and obstruct vibration and is provided with an balance adjusting system to lead the vibration to be fully absorbed and obstructed; thereby leading the noise to be reduced to a very large extent.
Description
Technical field
The utility model relates to vibration and noise reducing device, relates in particular to a kind of dismountable elevator vibration and noise reducing device.
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 dismountable elevator vibration and noise reducing device, comprise symmetrically arranged two groups of combined vibration-damping parts, inert block and balance adjusting portion part mutually, inert block simultaneously is provided with groove, the combined vibration-damping parts are arranged in the groove, the balance adjustment parts pass described inert block and the combined vibration-damping parts link together both, connect by attaching parts between two inert blocks.
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 dismountable elevator 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 symmetrically arranged two groups of combined vibration-damping parts 10, inert block 20 and adjustable bolt 30, and every group contains combined vibration-damping parts 10, inert block 20 and two adjustable bolts 30.Inert block 20 is arranged at combined vibration-damping parts 10 upper ends, and the two is by two 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 60.Elevator traction machine 70 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.Be respectively equipped with the fixed orifice 211 of adjustable bolt 30 in bottom portion of groove central authorities.Two inert blocks are connected by two channel-section steels 50.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.
