By the adoption of the technical scheme, the light shock wave resistant powder charging protection support simple and convenient to use has the advantages that the weight of the powder charging protection support is greatly reduced, production cost is reduced, damage capacity of secondary fragments is reduced and production technology difficulties of the powder charging protection support are greatly reduced.
Description
Technical field
The utility model belongs to Explosive protection device technique field, and what relate generally to is the easy shock resistance ripple of a kind of lightweight powder charge protective cradle.
Background technology
Along with the time-delay detonating technique is constantly used in engineering and scientific research and testing, the delay time of time-delay detonating technique has extended to a second level, and shock motion speed compares comparatively fast, has had influence on the explosive and the detonator that do not detonate in a short period of time.In order to protect explosive and to prevent induced detonation, the Explosive protection device must be set be protected.And existing protector mostly adopts steel material to make, and this class device exists structure heaviness, complex manufacturing technology, production cost height, the relatively poor problem of recycling performance.
Along with the demand of China to dissimilar shock wave researchs, need the more complicated shock wave of simulation.This kind shock wave generally can only adopt the time-delay detonating technique to simulate effectively in the blast wave analog machine.This kind powder charge scheme must be considered explosive protection and prevent damage to structure, and the damage effect of fragment to testpieces and structure that will prevent from exploding.Metal tube and metallic support structure are mostly adopted in existing powder charge measure; explosive is placed in the metal tube; but this kind powder charge support need be considered the safeguard measure to metal tube, prevents that metal tube from tearing pipe fitting and forming the metal fragmentation in the effect of detonation wave.The current wall thickness that mostly adopt to increase pipe fitting prevents the generation of fragmentation, but fresh charge support more all after at every turn having tested, the generation of secondary harm but can not be effectively avoided in big test for explosive payload.This kind safeguard measure cost height, difficulty of processing height, installation inconvenience, these disadvantages affect test accuracies, the experimentation cost of increase has reduced test efficiency, therefore needs a kind of more reliable powder charge protective cradle of development.
Technical scheme
For solving the problems of the technologies described above; the purpose of this utility model is to propose the easy shock resistance ripple of a kind of lightweight powder charge protective cradle; can adapt to the requirement of current relevant surge test, reach the purpose that reduces experimentation cost, shortens the test period, avoids secondary harm to damage.
The utility model is finished the technical scheme that above-mentioned purpose takes: the easy shock resistance ripple of a kind of lightweight powder charge protective cradle mainly comprises the corrugation support; sealing device; powder charge protection pipe fitting and circular draw-in groove; described corrugation support adopts corrugated board to make; have for the circular connecting hole that supports powder charge protection pipe fitting in the centre of corrugation support; described explosive protection pipe fitting is the cylindrical tube of hollow; linear explosive is installed in it; two ends flexible seal device shutoff; described explosive protection pipe fitting is fixed by a plurality of corrugation stent support, is provided with circular draw-in groove in the both sides of each corrugation support.
Be to support in a concentrically ringed wedge shape around the corrugation support described in the utility model.
Circular draw-in groove described in the utility model is middle disc-shaped structure, and the center has connecting hole.
The utility model adopts above technical scheme, has produced following beneficial effect:
1, reduces the weight of powder charge protective cradle significantly, reduce production costs.
2, reduce the damage ability of secondary fragmentation.
3, reduce the producting process difficulty of powder charge protective cradle significantly.
Description of drawings

Fig. 2 is the structural representation of the utility model corrugation support.
Fig. 3 installs the explosive mode for the utility model.
Among the figure: 1, explosive protection pipe fitting, 2, the corrugation support, 3, flexible seal device, 4, linear explosive, 5, circular draw-in groove.
The specific embodiment
By reference to the accompanying drawings, embodiment of the present utility model further is illustrated.
As shown in Figure 1: the easy shock resistance ripple of the described lightweight of present embodiment powder charge protective cradle mainly comprises explosive protection pipe fitting 1, corrugation support 2, flexible seal device 3 and circular draw-in groove 5; described corrugation support 2 adopts corrugated board to make; purpose is effectively to reduce the weight of powder charge protective cradle; reduce production costs, avoid the damage of secondary fragmentation.Having for the circular connecting hole that supports powder charge protection pipe fitting 1 in the centre of corrugation support 2, is to support (as shown in Figure 2) in a concentrically ringed wedge shape around the corrugation support 2.Described explosive protection pipe fitting 1 is the cylindrical papery pipe fitting of hollow, linear explosive 4(is installed as shown in Figure 3 in it), shutoff is carried out with flexible seal device 3 in two ends, and described sealing device 3 is the cylindrical, massive structure.Described explosive protection pipe fitting 1 is provided with circular draw-in groove 5 by a plurality of corrugation support 2 support fixation in the both sides of each corrugation support 2, described circular draw-in groove 5 is middle disc-shaped structure, and the center has connecting hole.
Present embodiment in use; make corrugation support 2 according to the cardboard of powder charge actual needs density reasonable in design and thickness and the paper tube of Rational Thickness and physical dimension; and get out rational circular orifice according to the size of explosive protection pipe fitting 1 at corrugation support 2, according to corrugation support 2 and the circular draw-in groove 5 of the length configuration fair amount of explosive protection pipe fitting 1.Corrugation support 2 is installed on the explosive protection pipe fitting 1 successively according to same orientation, and fixes corrugation support 2 with circular draw-in groove 5 and prevent that it is loosening, and smear the epoxy glue reinforcing.The Linear Shaped Charge 4 that designs is installed in the explosive protection pipe fitting 1, carries out shutoff with the two ends of 3 pairs of explosive protections of flexible seal device pipe fitting 1 at last.
