Background technique
At present, along with the development of modern television technology, increasing shooting will use all kinds of means of transportation such as automobile, aircraft, track.Use vidicon camera to face inevitably the needs of vibration damping at means of transportation, in order to reach good picture effect, preventing that float is excessive must carry out vibration damping to vidicon camera and process.
Existing vidicon camera vibration reduction platform mostly utilizes helical spring and guide rod to make, and complex structure, volume are larger, expensive.Therefore, design a kind of three-dimensional effectiveness in vibration suppression that has, environmental suitability is strong, and the small and exquisite vibration reduction platform of volume has become the demand in market.
Steel-wire isolator has been widely used in vibration isolation, antidetonation, buffering, anti-impact and the reduction construct noise of boats and ships, vehicle, building, bridge, engineering machinery, all kinds of electromechanical equipment and job facilities at present.Along with expanding economy, the vibration of modern project and impulsive control technical requirements improve constantly, and harsher Environmental Conditions is proposing higher requirement to vibration isolator.The isolation mounting of modularization also has the advantages such as all directions are safe and reliable, stable, easy to use except having good anti-vibration performance, be one of the development trend in vibration isolator field.
Under the same environmental conditions, vibration isolating effect depends on the rigidity of whole vibrating isolation system, and rigidity is less, and namely vibration isolator is softer, and vibration isolating effect is more remarkable, can be subject to the stability that different direction impacts by reduction equipment again but rigidity is too small.The rigidity difference of steel-wire isolator different bearer direction (such as vertical, 45 degree inclinations, lateral shear etc.) causes the anti-vibration performance of vibration isolator all directions different, when the vertical carrying of vibration isolator, vertical stiffness is maximum, substantially horizontal rigidity is minimum, if require to reach best vibration isolating effect this moment, vertical stiffness is reduced as far as possible, can cause rocking of equipment when or substantially horizontal higher when the equipment center of gravity produces vibration or impact at this moment, the stability reduction.
Summary of the invention
The purpose of this utility model provides a kind of vibration reduction platform that has large load, high damping, high-low temperature resistant, corrosion-resistant, long lifetime, shock resistance, wide band and have multidirectional low frequency vibration isolation, antidetonation and the reliable characteristics of structural safety.
According to the technological scheme that the utility model provides, a kind of damped platform comprises outer layer rack, internal layer frame and arm, also comprises steel-wire isolator; Wherein outer layer rack links to each other with some equally distributed arms, fixes by screwing locking nut between the two; Outer layer rack inside is provided with the internal layer frame, also is provided with several steel-wire isolators between internal layer frame and the outer layer rack, is fixedly connected with by screw between internal layer frame, outer layer rack and the steel-wire isolator.
Be provided with the through hole that can insert screw rod in the middle of the described internal layer frame.Described steel-wire isolator comprises helical elastic body and grip block.Described helical elastic body be 49 ~ 163 Stainless Steel Wires through the stranded Steel Wire Strand twisted wire that forms by symmetry or the coiling of antisymmetry structural type.
The utlity model has following advantage:
The utility model is applicable to the vidicon camera under the movement environment is vibrated isolation, can avoid unintelligible because vibrating the excessive picture that causes; Have superior anti-vibration performance, multi-direction vibration isolation, volume is little, and is lightweight, simple in structure, easy to use, the advantages such as easy accessibility.Also can be widely used in building, vibration isolation, antidetonation, the buffering of the aspect such as bridge, engineering machinery, electromechanical equipment and job facilities, namely satisfied vibration and the impulsive control requirement of modern project, improved again the multidirectional dynamic stability of system and reliability.

Embodiment
Such as Fig. 1 ~ shown in Figure 2, a kind of damped platform comprises outer layer rack 1, internal layer frame 2 and arm 5, it is characterized in that: also comprise steel-wire isolator 3; Wherein outer layer rack 1 links to each other with 6 equally distributed arms 5, and is fixing by screwing locking nut 4 between the two; Outer layer rack 1 inside is provided with internal layer frame 2, is provided with 6 steel-wire isolators 3 between internal layer frame 2 and the outer layer rack 1, is fixedly connected with by screw between internal layer frame 2, outer layer rack 1 and the steel-wire isolator 3.
Be provided with the through hole 6 that can insert screw rod in the middle of the described internal layer frame 2.Described steel-wire isolator 3 comprises the helical elastic body.Described helical elastic body be 49 ~ 163 Stainless Steel Wires through the stranded Steel Wire Strand twisted wire that forms by symmetry or the coiling of antisymmetry structural type.
During use, outer layer rack 1 connects arm, and internal layer frame 2 connects vidicon cameras, and the distortion by steel-wire isolator 3 can reduce the vibration that arm is delivered to vidicon camera.Steel-wire isolator 3 is the parts that exist in the prior art.Steel-wire isolator 3 has three direction vibration isolating effects, can isolate the vibration on the different direction, improves the camera views effect.
3 one-tenth symplex structures of steel-wire isolator are installed, and its attachment face becomes 90 degree with horizontal plane.Steel-wire isolator 3 comprises helical elastic body, grip block etc.Consist of overall structure by the Assembly mode of setting.The helical elastic body links by bolt and hardware.The steel wire diameter, number of share of stock, stranded helix angle that changes elastic body and spiral ring size and elastic body different assembling modes and the angle etc. in this project Structural Hardware frame can change rigidity, damping, bearing capacity and the stress of elastic body on all directions of space, to satisfy different requirements, can the safety and steady operation under the low frequency macro-energy disturbed condition that the assurance system goes up in any direction.
All hardwares are stainless steel, High Strength Structural Steel or high-strength aluminum alloy material and make among the embodiment, and impact resistance is strong, and structural strength is high, can adapt to various environmental conditions.
Damped platform to embodiment's preparation is tested:
1, static load deformation test: these two kinds of structures all have dry friction damping characteristics, friction owing to steel wire inside in its loading and the uninstall process causes the hysteretic damping effect, the pass of active force and its distortion is non-linear lag loop, can obtain this curvilinear characteristic by static test.
2, Frequency Response test: for studying the damping property of these two kinds of products, test specimen is loaded the counterweight of different quality, use respectively its frequency response transfer function of arbitrary excitation and sine sweep measurement of test method, the peak response frequency of analytical calculation system, vibration transmissibility, damping be the parameter such as power augmentation factor when.
By experimental result as can be known, when the vibration and the impulsive disturbance that come from any direction transmission, when especially the large displacement of low frequency disturbs (such as seismic waves, explosive blast etc.) to act on the damped platform of present embodiment preparation, to after the absorption of input energy and consuming, make the response decrease that is passed on engineering equipment or the facility through the helical elastic body.System's minimum peak response frequency of its realization can reach below the 3Hz, so the buffer action that the low frequency macro-energy of this class character is disturbed is very effective too.
