Description
Technical field
The utility model belongs to explosion welding technique field, specifically, is related to a kind of cellular pillbox of explosive welding.
Background technology
Explosive welding is a kind of using high-power energy caused by explosive detonation as the energy, makes of the same race or dissimilar material
High velocity impact occurs, and forms the High-Energy Process of metallurgical binding between metal.Explosion composite technology is as a kind of cheap, efficient
New welding technology, have many advantages, such as that material compatibility is strong, bond strength is high and cycling processability is good.It has answered extensively at present
For fields such as oil, chemical industry, electric power, nuclear energy.
But explosive welding then needs constantly to carry out experimental study, probes into its weldering as a kind of emerging welding technique
Pick reason.And traditional explosive welding carries out in the wild, in general farther out apart from processing factory position, and explosive welding quality is held
It is vulnerable to the influence of weather, causes with batch product quality difference, while the sound for generation of exploding and vibrations are very big to ambient influence.
In addition, the research unit of coastal area, test site is often closer from resident, to ambient influence bigger.Therefore it is badly in need of a kind of
It can eliminate or substantially reduce the scheme of the influence of explosive test generation.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of cellular pillbox of explosive welding,
It is semi-closed structure, and structural strength is high, and weight is relatively light, and the excellent effect with sound insulation and damping.
What the utility model aim was realized in：A kind of cellular pillbox of explosive welding, key are：Including fort
Body and lid are set to be pushed up with the fort on the fort body, and the wall on the fort body and fort top includes successively from inside to outside outer cover of steel plate, subtracts
Shake layer and sound absorbing layer；Through-hole is distributed in honeycomb fashion on the fort body and the wall on fort top, and the ground in the fort body faces upward successively
It is equipped with shakeproof layer and welding basal layer.
Using the above structure, the noise of explosion and vibrations absorb a part in pillbox by buffer layer and sound absorbing layer, so
It is a part of by the through-hole absorption of honeycomb fashion distribution afterwards, and the air-flow that explosive expansions generate, it can be discharged by through-hole, reduce pillbox
The stress in fort is impacted, and is protected pillbox, is also reduced vibrations and noise effect.
Preferably, above-mentioned through-hole is hexagonal hole.
Since the vibrations of explosive welding are mainly by overland propagation, using the above structure, shakeproof layer can will weld base
Plinth layer completely cuts off with ground, can effectively prevent the propagation of vibrations, hexagonal hole from being distributed plus cellular, can make pillbox shape
At the structure similar to honeycomb, and class honeycomb structure is high with intensity, rigidity is big, stability is good, while regular hexagon boring ratio one
As circular hole or other polygonal holes it is structural more preferable, while also having the effect of sound-absorbing damping, can be effectively applied to
On the pillbox of explosive welding；The design of also class honeycomb structure can also reduce the influence of electromagnetic interference.
Preferably, the inner wall of above-mentioned through-hole is equipped with one layer of sound-absorbing material layer.
Using the above structure, the noise elimination effect of through-hole is further increased.
Preferably, it is stamped convertible cover board at the external port of above-mentioned through-hole.
Using the above structure, when not in use, cover board can cover through-hole, have the function of that shading is taken shelter from rain, while can also prevent
Only birds fly into or other animals climb into along through-hole.
Further, it corresponds to the cover board on the outer wall of above-mentioned fort body and is equipped with a buffer spring, which is located at
Buffer spring upper end side is simultaneously fixedly installed close to the side of the cover board.
Using the above structure, cover board is washed in the gas shock of generation of exploding open, and gas is discharged from through-hole, and cover board is impacted
Overturning, buffer spring have the function of buffer protection cover board, and the back shroud that exploded can be sprung back under the effect of the elastic force of buffer spring
And through-hole is covered again.Cover board is protected, meanwhile, the shortcomings that being unable to return after also cover board being avoided to wash open.
Further, the outer wall that the upper end of above-mentioned cover board is pushed up with the fort body or fort is hinged.
Using the above structure, cover board can be in self gravitation effect lower cover on through-hole, while cover board, when washing open, itself is heavy
Power can resist a part of impact force, reduce buffer spring stress, moreover it is possible to which, in the case where buffer spring rebound is inadequate, cover board exists
Return under self gravitation effect.
Preferably, above-mentioned fort body is cylindrical, and the fort top is in hemisphere face arc top.
Using the above structure, circular configuration can effectively disperse blast impulse, and can push up impulse force to fort and converge and release
It puts, reduces the impact on ground, earth shock also accordingly reduces.
Above-mentioned shakeproof layer and buffer layer can be used high polymer vibration absorptive material and be made, described such as ACF artificial cartilage foams
Sound absorbing layer and sound-absorbing material layer can be used metallic aluminium fiber absorbing material and be made, and the carbon of high-strength material can be used in the cover board
Limit material is made.
Advantageous effect：
The cellular pillbox of a kind of explosive welding of the utility model, it is possible to reduce the influence of vibrations and noise, honeycomb structure
A part is absorbed in pillbox inner wall with intensity height, light-weight, sound insulation and cushioning effect, explosion noise and vibrations, passes through bee
A part is absorbed when Nest architecture again, can obviously reduce the influence to resident, in addition the pillbox can according to the needs of real work, into
Row etc. is than amplification and reduces.
