Shock wave protective guard and application thereof in explosive welding

Technical Field

The invention relates to the field of explosive welding, in particular to a shock wave guard railing and application thereof in explosive welding.

Background

The explosive welding is a welding method which utilizes the high pressure of shock waves generated during the detonation of explosives to drive metals to move, the two metal surfaces collide to form jet flow, surface films are removed, and metallurgical connection is formed under the action of the high pressure of the shock waves. Explosion welding is generally performed in an open field outdoors, and in addition to being used for welding metal, some of shock waves generated during operation diffuse from an explosion area to the periphery, and affect the surrounding environment.

In this specification, the schematic representations of the terms used above are not necessarily intended to refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

The embodiment of the invention provides a shock wave guard fence which is made of elastic renewable biological materials or plastic materials. The elastic renewable biological material and the plastic material are elastic materials, so that the shock wave guard fence has certain elasticity, and can effectively distribute and weaken the explosion shock wave, thereby reducing the influence of the shock wave on the surrounding environment and prolonging the service life of the shock wave guard fence. In addition, the elastic renewable biological material can be obtained from local materials, has short growth period, strong regeneration capability, rich resources, low cost and environmental protection; the plastic material is also low in cost, convenient to replace and maintain and short in time consumption.

In one embodiment of the present invention, the elastic renewable biomass material is bamboo, which can be processed into bamboo chips or rods.

In another embodiment of the present invention, the elastic renewable biomass material is wood, and can be processed into sticks, wood chips, or the like.

In one embodiment of the present invention, as shown in fig. 1, the shock wave guard rail is composed of a plurality of rows of spaced balustrades 1, the balustrades 1 are composed of a plurality of balustrades 2 arranged in a straight line, and the distance between adjacent balustrades 2 is 1-100 cm, preferably 10-50 cm, for example, 10cm, 20cm, 30cm, 40cm or 50 cm. The guardrail formed by multiple rows of railings arranged at intervals is beneficial to shock wave diffusion, and the flow direction of the shock waves is changed for multiple times, so that drainage is reduced, and the purpose of reducing protective shock waves is achieved. The distance between the railing posts is controlled to be within 1-100 cm, so that shock waves can be diffused, the damage of the impact force of the shock waves to the railing is reduced, the shock waves are guided to interfere with each other, and the intensity of the shock waves is reduced.

In one embodiment of the invention the diameter of the newel 2 is 1-15 cm, preferably 3-10 cm, for example 3cm, 5cm, 7cm or 10 cm. If the diameter of the handrail is less than 1cm, the strength is low and the elasticity is insufficient; the diameter of the handrail is larger than 15cm, the material source is limited, and the maintenance cost is greatly improved.

Furthermore, in the whole shock wave guard railing, the guard posts 2 with uniform diameters can be adopted, the arrangement mode that the coarse diameters and the fine diameters are spaced can also be adopted, and meanwhile, the distance between the guard posts 2 with the fine diameters can be adaptively adjusted according to the requirements.

In one embodiment of the invention, the balustrade columns 2 are connected to each other by a wire or a cord.

In another embodiment of the invention, the newel posts 2 are not connected and stand independently.

In one embodiment of the present invention, the number of the rows of the balustrade 1 is 2 to 20, preferably 3 to 10, and for example, may be 2, 3, 5, 8, 10 or 15. The number of the handrail rows is too small, the effect of guiding and weakening the shock waves is not obvious, and too much material is wasted.

Further, the distance between two adjacent rows of railings 1 is 10-50 cm, preferably 40-50 cm, for example, 10cm, 20cm, 30cm, 40cm or 50 cm. The too close then shock wave interference space that two adjacent rows of railing are separated is not enough, reduces the effect of shock wave and descends, and too far away then need occupy the place too much, does not utilize the rational utilization in place space, therefore 10 ~ 50cm are more suitable.

Further, the mutual staggering of the railing posts 2 of two adjacent rows of railings 1 is more beneficial to guiding and weakening impact waves, and preferably, the railing post 2 of the rear row of railing 1 is positioned in the middle of the railing post 2 of the front row of railing 1.

In an embodiment of the present invention, the heights of the railings 1 in each row are different from each other, the height of the railing 1 near the center of the explosion is the lowest, and is 1.5-2 meters, specifically 1.5 meters, 1.8 meters, or 2 meters, and the heights of the railings 1 behind the railings increase by 0.3-2 meters, for example, 0.3 meter, 0.6 meter, 1 meter, or 2 meters. The height difference is designed, so that the impact force of the inner-layer railing can be reduced, and the service life of the whole shock wave guard rail can be prolonged.

The embodiment of the invention also provides application of the shock wave guard railing in outdoor explosion welding, and particularly as shown in fig. 2, the shock wave guard railing 3 is arranged around an explosion welding field in a fixed or inserted mode.

When the fixed type is adopted, the bottom of the railing post can be directly buried in the foundation of an explosion welding field for fixation.

When the insertion type is adopted, concrete can be poured on an explosion welding field in advance, an insertion groove 4 of the railing post 2 is reserved, and the railing post 2 is fixed by other materials after being inserted, as shown in fig. 3. The plug-in type has higher cost at the initial stage, but the replacement and the maintenance at the later stage are convenient.

Although the invention has been described in detail hereinabove with respect to a general description and specific embodiments thereof, it will be apparent to those skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
