Abstract
The invention relates to a parallel-serial-connecting combined-type vibration isolator. The parallel-serial-connecting combined-type vibration isolator comprises an upper covering plate, a middle covering plate, a base plate, clamping bolts, a vibration isolation block, damping blocks and an adjustment displayer, wherein elastic elements I are symmetrically arranged between the upper covering plate and the middle covering plate, elastic elements II and damping elements are symmetrically arranged between the middle covering plate and the base plate and connected through the clamping bolts, and the damping blocks are laid around and inside the covering plates. Reinforcing rib plates are fixed around the covering plates, the vibration isolator is divided into two layers and provided with the elastic elements, and the elastic coefficients of the elastic elements are different or the same. Due to the facts that the elastic elements of the vibration isolator are vertically combined and damping materials are laid, the resonance phenomenon can be prevented, the vibration amplitude is prevented from being too large, and the vibration isolation effect is good. The vibration isolator is of an integrated structure, thereby being convenient to convey and install. When the vibration isolator is installed, the pressure or the amount of compression is observed through the adjustment displayer, and the vibration isolator is controlled to be in the best state.
Description
Technical field
The present invention relates to Environmental Engineering noise control technique field, is a kind of and series hybrid vibration isolator.
Background technique
For protection of the environment, solve the solid-borne sound transmission producing because of vibratory equipment, need to take vibration isolation to vibratory equipment, therefore designed various vibration isolators.But there are some defects in the vibration isolator of standard or the nonstandard product of having declared.Standard isolators is because of its shape, and the problems such as performance can not where applicable, just need to design nonstandard vibration isolator.The defect of nonstandard vibration isolator is in the past: (1) vibration isolation block disperses, there is no mounting base, rigidity is low, transportation and installation are inconvenient, (2) there is no damping member, itself has resonance phenomenon vibration isolator, particularly, for the larger equipment of vibration amplitude, vibration isolating effect is poor, easily produces rigidity and contact between (3) vibration isolation block and gusset, affect vibration isolating effect, for environmental standard, require strict occasion, the natural frequency of vibration isolator was higher in the past, and vibration isolation efficiency can not be satisfied the demand, (5) vibration isolator is not necessarily in optimum Working, and scene lacks adjusting program etc.
The vibration isolator invention of having declared has < < Combined vibration isolator > >, patent No. ZL2010.2.0140630.6; < < combined type vibration isolator > >, the number of accepting 201320491115.6.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of and series hybrid vibration isolator, this vibration isolator not only natural frequency is lower, can also prevent resonance phenomenon and control amplitude, vibration isolating effect is better, and structure-integrated, convenient transportation and installation, and by display register pressure and decrement, guarantee that vibration isolator is controlled at optimal load or working state.
For overcoming the above problems, the concrete technological scheme that the present invention adopts is as follows: and series hybrid vibration isolator, comprise upper cover plate, cover plate, base plate, clamping bolt, vibration isolation block and damping block, adjusting display device composition, it is characterized in that: described elastic element I and damping block symmetric arrays, between upper cover plate and cover plate, and couple together by link I; Described elastic element II symmetric arrays, between cover plate and base plate, and couples together by link II.In the surrounding of elastic element II and the inside of upper cover plate, be equipped with damping plate.Damping plate is laid in the inside in described upper cover plate, cover plate.Along cover plate surrounding, be fixed with and strengthen gusset 1.Elastic element 4, elastic element 7 and damping block 6 various combinations, point Dual-layer, composition cascaded structure.
Elastic element I and elastic element II, can like combinations in elasticity coefficient, also can various combination.
Described and the composite vibration isolator of connecting, has Dual-layer structure, and the lower reinforcement gusset of natural frequency has reduced the distortion that cover plate produces because of load, improves vibration isolator intensity.
Advantage of the present invention is: and series hybrid vibration isolator adopts elastic element and damping material composite structure, prevent resonance phenomenon, control amplitude and load simultaneously, make the effectiveness in vibration suppression of product better, the inside at elastic element four and each cover plate is equipped with damping plate, the noise of generation of vibration is absorbed, prevents to be rigidly connected simultaneously.
