Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The device for inhibiting the diffusion of the explosive products comprises a supporting frame 1, a spraying mechanism 3 and a buffering mechanism 4, wherein the buffering mechanism 4 is arranged at the top of the supporting frame 1, a protective structure 2 is arranged around the supporting frame 1, the spraying mechanism 3 comprises spray heads 32 and spraying pipelines 31, the spraying pipelines 31 are circumferentially arranged around the upper part of the supporting frame 1, the spray heads 32 are connected to the spraying pipelines 31 at intervals, and the spray heads 32 are positioned on the outer side of the protective structure 2.
As shown in fig. 1 and 2, when in use, the device for inhibiting the diffusion of explosive products is arranged above a manhole dug pile to cover an orifice, and the bottom of the support frame 1 needs to be connected with a foundation or is provided with a heavy object to prevent the shock wave generated by explosion from striking off the frame. During the blasting, buffer gear 4 at braced frame 1 top can reduce the impact and prevent rubble granule vertical departure, combines protective structure 2 with rubble, dust etc. interception inside protective structure 2, and protective structure 2 outside all around sets up the shower nozzle 32 of spraying simultaneously, makes the mode through the spraying, makes the tiny dust that sees through protective structure 2 subside to reach the mesh that restraines the diffusion of explosive product.
During blasting, the top cover plate 42 can prevent broken stone particles from flying out vertically, the top cover plate 42 can move up and down and move upwards under the blasting impact force, when the top cover plate 42 rises to reach the energy-absorbing elastic piece 43, the top cover plate 42 is prevented from colliding with the top pressure beam 41 at the buffering descending speed of the energy-absorbing elastic piece 43, the impact action borne by the top cover plate 42 is relieved, and the possibility of damage to the top cover plate 42 and the support frame 1 is reduced. The energy absorbing elastic member 43 may be a spring, an airbag, or the like.
The top pressure beam 41 can be arranged right above the top cross beam 11, and can also be arranged at the middle position of the top of the supporting frame 1, and in order to prevent the top cover plate 42 from deforming and flying out after being impacted for many times, the top pressure beam 41 is of a cross structure, the cross top pressure beam 41 can form a cross barrier above the top cover plate 42, and even if the top cover plate 42 deforms, the top cover plate is not easy to fly out.
The top compression beam 41 is usually connected to the support frame 1 by the ends, and the energy absorbing elastic members 43 are located at the most stressed positions, and the energy absorbing elastic members 43 are disposed near the ends of the top compression beam 41 in order to prevent the top compression beam 41 from bending due to the impact force.
The function of the protective structure 2 is to prevent the escape of crushed stones and dust, which may be a commonly used dust-proof structure, however, in the preferred embodiment of the present application, the protective structure 2 includes a fixed frame 21, a wire 23 and a dust-proof net 22, the fixed frame 21 is connected to the supporting frame 1, the wire 23 and the dust-proof net 22 are both connected to the fixed frame 21, and the wire 23 is located outside the dust-proof net 22.
