Abstract
The utility model relates to a vibration control project equipment especially to an adjustable mass ratio dual layer vibration isolation device comprising a vibration source and the first layer of vibration isolation device directly connected with the vibration source. The bottom of the first layer of vibration isolation device is connected with the second layer of vibration isolation device through the medium mass block. The different point is that the medium mass block is provided with mass adjustment cavity. The mass adjustment cavity is filled with fillers. The beneficial effects of the utility model lie in:1.the utility model changes the problem that the vibration isolation characteristic parameter is fixed, and is not easy to adjust when the dual layer vibration isolation device is in practical use. Through dynamic adjustment to the mass of the medium mass block, the vibration natural frequency of the utility model is changed and the error in work is reduced and the best working state of the vibration isolation characteristics of the vibration device is reached thus the scope of application of the device is enlarged.2.A further vibration elimination and vibration reduction effect can be achieved through filling granular or powdery materials in the mass adjustment cavity.
Description
Technical field
The utility model relates to a kind of vibration control engineering equipment, particularly relates to a kind of adjustable quality than double-layer vibration isolating device.
Background technique
The double-layer vibration isolating device is a kind of isolation mounting efficiently that grows up on the single-layer partiting polarization basis, can improve the vibration isolation usefulness to vibration source effectively.It mainly be by two-layer vibration isolator and between the intermediate mass piece constitute.Intermediate mass piece and the important parameter that by the mass ratio of the vibration source of vibration isolation is decision isolation mounting vibration isolating effect.At present, the quality of the intermediate mass piece of the isolation mounting of practical application is a fixed value, thus the quality of intermediate mass piece be a fixed value by the theoretical ratio of device for vibration insutation quality.It for example is a kind of isolation mounting that is used for air conditioner of CN2703987 at the disclosed publication number of 2005.06.08, by two-layer vibration isolator and between connecting plate constitute, it lacks the technical measures of adjustable parameters, and performance parameter is unalterable after design, manufacturing, installation.Since can not be in full accord by the characteristic of the equipment of vibration isolation, also there is certain difference between the isolation mounting of manufacturing simultaneously and the design load, and therefore, there is certain deviation in the isolation mounting of practical application with the optimal design working state inevitably.
Summary of the invention
Technical problem to be solved in the utility model be the deficiency that exists at prior art and a kind of adjustable quality that provides than double-layer vibration isolating device, it can conveniently adjust the intermediate mass piece with by the mass ratio of vibration isolation vibration source, to improve the vibration isolation usefulness of isolation mounting.
The utility model is that the technological scheme that problem adopted of the above-mentioned proposition of solution is: comprise vibration source 1 and the first layer vibration isolator 2 that directly links to each other with vibration source, the bottom of first layer vibration isolator links by intermediate mass piece 5 and second layer vibration isolator 4, its difference is that described intermediate mass piece 5 is provided with quality and adjusts cavity 3, and quality is adjusted in the cavity packing 6 is housed.
According to technique scheme, described quality is adjusted cavity can be the integrated type cavity, or is combined by a plurality of partitioned cavity.
According to technique scheme, described quality is adjusted and is provided with packing interpolation mouth 7 above the cavity.
According to technique scheme, described packing is granular or powdered substance.
The beneficial effects of the utility model are:
1, changed the problem that double-layer vibration isolating device isolation characteristics parameter in actual applications immobilizes, is difficult to adjust, dynamically adjust by quality middle mass block, change its Natural Frequency of Vibration, reduced the error of work, make the isolation characteristics of isolation mounting adjust to optimum Working, thereby improve the Applicable scope of device;
2, loaded particles shape or powdered substance in quality is adjusted cavity can play the effect of further weakening vibration damping.
Description of drawings
Fig. 1 is an embodiment's of the utility model main TV structure figure.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Comprise vibration source 1, vibration source is generally electromechanical equipment, vibration source below directly links with first layer vibration isolator 2, first layer vibration isolator bottom connection intermediate mass piece 5, and described intermediate mass piece is the steel structure seat, rectangular skeleton frame shape, the centre is provided with all-in-one-piece quality and adjusts cavity 3, and quality is adjusted in the cavity and is added with packing 6, and described packing can be granular iron sand, quality is adjusted and is offered packing interpolation mouth 7 above the cavity, and the configuration capping; Intermediate mass piece below links by second layer vibration isolator 4 and fixed pedestal 8.Constitute an adjustable quality thus than double-layer vibration isolating device.
The actual process of using of the present utility model is: after being in place with isolation mounting with by device for vibration insutation (vibration source), open operation by the equipment of vibration isolation (vibration source), progressively in adjusting cavity, quality adds packing, quality to middle mass block is dynamically adjusted, up to the vibration isolating effect of isolation mounting reach best till.
