Description
Technical field
The invention belongs to a kind of buffer shock-absorbing packaging system, be specifically related to a kind of floating raft type double-layer bumper vibration insulating system that is applicable to the severe traffic condition in inland, polar region.
Background technology
The breakage resistant luer intensity of product generally all should be less than the crippling strength of extraneous harmful factor.If do not have wrapped protection, product will be damaged very soon.Therefore must be with the external buffer cushion packaging to improve the breakage resistant luer intensity of product.Transportation buffer shock-absorbing packing, be, in order to reduce as far as possible the transportation circulation process, product is caused to damage, ensures the safety of product, facilitates the accumulating handling, the packing that the transportation accumulating of take is main purpose.Transport package commonly used mainly applies to the standard highway transportation now, and common seat transport also lacks the Packaging buffering method for the severe transportation environment in inland, polar region at present.
Main buffering package vibrating isolation system is single-layer partiting polarization at present.The single-layer partiting polarization package design is simple and convenient, but being mainly manifested in, the shortcoming that himself is arranged can not isolate low-frequency vibration excitation and high-frequency vibration excitation simultaneously, to low-frequency excitation, system requirements system vibration isolation rigidity must be very little, if only adopt the single-layer partiting polarization method can cause system too soft, lack necessary stability.
General daily road transport, road conditions are better, vibration and impact acceleration are smaller, and due to lorry self with suspension gear, therefore have the effect of certain vibration damping, and the oscillation frequency of its generation also mainly concentrates near the frequency of suspension, therefore adopt the mode of single-layer partiting polarization just to pack and can reach good damping effect it.But the Antarctic Inland transportation does not have the ordinary traffic instruments such as lorry, but adopt the dilatory number of a snowfield transport trolley to hang the mode that sled advances, according to measurement in recent years, in the Antarctic Inland transportation, there is no fairly obvious oscillation frequency concentrated area, it is wide that its vibration characteristic presents frequency band range, the characteristics that vibration acceleration numerical value is large.
Ice dome A area, the South Pole is positioned at the cold Antarctica, and height above sea level 4093m is the highest area of Antarctic Inland ice sheet height above sea level, and climatic conditions are exceedingly odious, are called as " utmost point that can not approach ".It is also the desirable place of carrying out the scientific observations such as snow ice modern process, atmospheric science, space physics and astronomy observation simultaneously, has extremely important scientific value.Ice dome A area has more than 1,000 kilometer apart from Antarctic Ocean water front.According to the existing road vibration data of measuring, the vibratory impulse accekeration of Antarctic Inland transportation is far above the requirement of the packing standard of transportation commonly used of current China.According to the needs of Antarctic Inland area scientific investigation and exploitation, all require to provide a kind of buffer shock-absorbing manner of packing of applicable Antarctic Inland scientific investigation requirement; And there is no applicable technical scheme in prior art.
Summary of the invention
The objective of the invention is to make up the deficiencies in the prior art, a kind of floating raft type double-layer bumper vibration insulating system that is applicable to the severe traffic condition in inland, polar region is provided, can meet the requirement of Antarctic Inland scientific investigation transportation, precision instrument is carried out to safety precaution.The present invention utilizes distinctive inland, the South Pole self vehicle-sled as intermediate, and the structure of sled is transformed, and can both adapt to the needs of double-layer vibration isolating, does not separately increase again new intermediate, realizes the oscillation damping method of double-layer vibration isolating.
The technical scheme that completes the foregoing invention task is, a kind of floating raft type double-layer bumper vibration insulating system that is applicable to the severe traffic condition in inland, polar region: precision instrument to be transported is arranged in packing chest, this packing chest is arranged on transportation sled (vibrating mass), be provided with the sled bumper on this sled, form the individual layer Buffering Isolation System, it is characterized in that, on this individual layer Buffering Isolation System, be provided with second layer Buffering Isolation System, the structure of this second layer Buffering Isolation System is, described packing chest is (also referred to as fixing framework by a carrying case, or steelframe) be fixedly installed on the transportation sled, all be fixed with the carrying case shock absorber on six faces in this carrying case, six faces of described packing chest are to be fixed in this carrying case by described carrying case shock absorber, in the scope that packing chest can be drawn a circle to approve at the bumper of six faces, are free to slide, and reach the effect of vibration damping.
The present invention has following prioritization scheme:
1. sled is improved, add on sled and increased light spring formation individual layer (ground floor) Buffering Isolation System.The rigidity of this spring is determined (weight of precision instrument is less, and the rigidity of spring is also less) by the weight of precision instrument, with the vibration that reduces high frequency with impact the impact that precision instrument is brought.Individual layer Buffering Isolation System on described sled is improved: on the sled bumper (carrying case below), increase a sled reinforcing member, as intermediate (or being called matrix) to increase the rigidity between ground floor shock mitigation system and second layer shock mitigation system.
2, described sled reinforcing member (intermediate or matrix), require 2 times of left and right that its quality is vibrating mass (carrying case) quality.
3, described carrying case shock absorber adopts low temperature grease rubber damper.
4, three faces of described carrying case (fixing framework or steelframe) are stationary plane (weld together); Three faces in addition are active face, adopt adjusting hole to connect.So that the predetermincd tension that carrying case is regulated shock absorber while installing.
5, be pasted with the polytetrafluoroethylene pad on six of described packing chest inside faces, to guarantee that packing chest is free to slide in the scope of carrying case shock absorber, six-freedom degree is not restricted.
6, in described packing chest, at the flexible material packaging protecting precision instrument for surrounding of precision instrument;
7,, at the flexible damping material differed of the bottom of precision instrument pad, can prevent the impact of the vibration of sudden surge and long-time transportation generation on instrument.
8, between described carrying case (steelframe) and sled, adopt screw to be connected.
9, be placed with desiccant in carrying case, make moist to prevent transportation.
For long-time, without the Transport Vibration of specific incentives frequency separation with impact and need to adopt double-layer vibration isolating system to obtain vibration isolating effect preferably.The present invention adopts double-layer vibration isolating system, between the vibration isolation packing of protecting at needs exactly and vibrational excitation source, add an intermediate as matrix, vibrating mass flexibly is arranged on intermediate, and then the single-layer partiting polarization device of vibrating mass and intermediate composition flexibly is arranged on the vibration source basis.The main larger vibration isolation element of rigidity that adopts between its intermediate and excitation vibration source, with the vibration that reduces medium high frequency with impact the impact on vibrating mass, adopt the little vibration isolation element of rigidity between vibrating mass and intermediate, reduce the impact of low-frequency vibration.For intermediate, 2 times of left and right that its quality of General Requirements is the vibrating mass quality.
