The drop impact loading device of body formula.
Background technique
Structure shock resistance refers mainly to the mechanical property that structure is shown under critical shock load action.Extreme punching
The effect of hitting has the characteristics that the density of load is high, action time is short, energy sharply converts.It is obvious poor that it has with conventional action of static load
Different, material will be presented nonlinearity under strong Under Dynamic Load in short-term, and Response Mechanism is complicated, correlative study be always protection works and
Hot and difficult issue civilian, in Industrial Engineering building.It is more difficult that theoretical and simulation study is carried out for it, it is logical that research is mostly at present
Overtesting carries out.Its engineering background corresponds to extremely complicated operating condition, has higher requirements to test facilities.Existing falling weight impact test dress
It sets that cost is high, projection is fixed vulnerable to interference, test platform, hoisting depth and limited mass, and does not have test specimen transhipment and remote
Journey is remotely controlled projection function.
Summary of the invention
The object of the present invention is to provide one kind to be able to carry out long-distance remote control projection, projection is not closed on facility interference, and
Hoisting depth and weight can be according to the falling weight impact test devices that operating condition adjusts on a large scale.
The invention mainly comprises lifting device, hawser, electric permanent-magnet suction disc, projection bodies, test platform pedestal, protection machine
Structure, electric permanent magnetism generator, the wireless remote control projector and pylon.
Wherein, the top of pylon is equipped with lifting device, and hawser is equipped on lifting device, and the fixing end of hawser is located at promotion
On device, the free end of hawser is connected with electric permanent-magnet suction disc.It is projection body in the lower part of electric permanent-magnet suction disc.Test platform base
Seat is located at the underface of projection body, for placing, fixing test component.Protection machine is equipped with around test platform pedestal position
Structure, protection mechanism are light weight board, prevent test specimen fragment from flying.Electric permanent magnetism generator cooperation electric permanent-magnet suction disc is used together, and is used
Magnetic in providing to electric permanent-magnet suction disc, radio remote control switch built in electric permanent magnetism generator can be controlled by the wireless remote control projector
Electric permanent magnetism generator is supplied, is powered off, and then is controlled the generation of electric permanent magnetism, eliminated, and realizes that body projects.
Further, pylon can be fixed pylon, or directly use autocrane as pylon.
Further, fixed pylon passes through hound phase by four steel pipes as support tube between adjacent supports pipe
Connection.Fixed pylon can be according to test height demand segmented-erection.Lifting device is bridge motor, is located at fixed pylon
Top.
Further, for autocrane as pylon, the included hoisting mechanism on autocrane just can be used as above-mentioned mention
Rise device.
Further, projection body can be cast according to the missile original shape demarcated in test, need to be steel bullet.
In the use of the present invention, needing that test platform pedestal first is fixed in test specimen placement, and electric permanent-magnet suction disc is placed in examination
Body bottom is tested, electric permanent magnetism generator is then controlled by the wireless remote control projector, generates electric permanent-magnet suction disc magnetic by body
It is sucked.Body is then promoted to by specified altitude assignment using lifting device, then electric permanent magnetism is controlled using the wireless remote control projector and is occurred
Device makes electric permanent-magnet suction disc magnetism disappear, and then realizes body projection.
The invention has the following advantages over the prior art:
1, the configuration of the present invention is simple, convenient for materials, installation is simple, cheap, mainly using existing more mature
Integration ofTechnology is built；
2, each module performance can be given full play to, realizes that projection exempts from interference, changes hoisting depth and weight according to test demand,
Realize that test site flexible and selectable, device have test specimen transhipment and remote control projection function；
3, facilitate test to greatest extent, improve the functions such as test safety guarantee.
