Description

Technical Field

[0001] The utility model relates to the technical field of air-spaced charge, in particular to an air-spaced charge structure. Background Art

[0002] Air gap charging is a special charging technology that controls the propagation of explosion waves and energy release by setting air gaps between explosive materials. This technology is widely used in military and civilian fields, such as mines, artillery shells, explosives, etc., and can adjust the explosion effect as needed to improve safety and efficiency. The principle of air gap charging is to use air as a buffer medium to slow down the propagation speed of the explosion wave, thereby reducing damage to the surrounding environment. At the same time, this charging method can also improve the utilization rate of explosives, reduce unreacted explosive residues, and reduce pollution. When designing and using air gap charging, factors such as the size, shape, and distribution of the air gap need to be considered to achieve the best explosion effect. However, the existing gun barrels are all deep. When the explosives are placed from the upper end of the gun barrel to the lowest end, the explosives will fall directly to the bottom of the gun barrel, making the explosive packaging prone to cracking, resulting in damage to the outer packaging of the explosives, which will reduce the sealing of the explosives and damage the internal structure of the explosives, affecting its explosion effect or safety.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model proposes an air-spaced charge structure. When it is necessary to put the explosive and the air spacer into the gun barrel, the explosive is placed on the surface of the bottom plate, and the blocking component is pressed to allow the clamping plate to be pushed by the arc spring, so as to clamp the explosive. At this time, one side of the plane of the triangular baffle plate will fit with the inner wall of the limiting groove, so as to control the flipping and clamping angle of the clamping plate to prevent excessive clamping force from damaging the explosive. When the explosive is placed, the operator can loosen the bottom plate and let the bottom plate slowly descend by the weight of the explosive itself. Before this, the semicircular block is lowered to the top of the layer where the explosive is placed and then fixed, etc. When the bottom plate descends until the lower surface of the long plate contacts the outer surface of the semicircular block, the reset plate will push up and allow the clamping plate to rotate in the opposite direction, thereby loosening the clamping plate holding the explosive. As the reset assembly connects to the semicircular block and the bottom plate continues to descend, the bottom plate will rotate from a horizontal state to a vertical state. The explosives on the upper surface of the bottom plate will slide to the bottom of the barrel due to the reverse rotation of the clamping plate, which loosens the explosives. At this time, the bottom plate is away from the explosive layer and in contact with it, so the explosives can fall safely on the explosive layer, thereby ensuring the integrity of the explosives when they are placed.

The long plate 244 is below the bottom plate 21, and the slope B242 is adapted to the inclined groove A223. The reset plate 241 is moved upward by pushing up the long plate 244, so that the clamping plate 22 is flipped over, and the explosive is disassembled.

[0033] The positioning assembly 3 includes an I-shaped plate 32 movably arranged inside the positioning groove 14, a semicircular block 31 fixedly installed on one side of the I-shaped plate 32, the semicircular block 31 and the long plate 244 are on the same vertical line, four groups of spring rods D34 are fixedly installed on the inner wall of the I-shaped plate 32, two groups of spring rods D34 are symmetrically arranged with the other two groups of spring rods D34, an L-plate 33 is fixedly installed at one end of the spring rod D34, one end of the L-plate 33 is adapted to the positioning hole 15, a pull plate 36 is slidably arranged on the upper surface of the two groups of L-plates 33, a plate groove 37 is opened on the lower surface of the pull plate 36, the other end of the L-plate 33 slides inside the plate groove 37, a double-headed spring rod 35 is fixedly installed between the two groups of L-plates 33, and the semicircular block 31 can be stopped at a predetermined position by pulling the pull plate 36, so that the outer surface of the semicircular block 31 contacts the lower surface of the bottom plate 21, thereby allowing the bottom plate 21 to rotate.

[0034] Working principle: When it is necessary to put the explosive into the bottom of the barrel 1, the operator fixes the bottom plate 21 on the upper end of the barrel 1, and then puts the explosive into the surface of the bottom plate 21 while pressing down the pressure plate 232, so that the blocking assembly 23 as a whole enters the interior of the groove 25. At this time, the clamping plate 22 is no longer blocked by the triangular baffle 238 and the rectangular plate 233, and the arc spring 225 will release the tension, allowing the clamping plate 22 to continue to rotate, thereby clamping the explosive. When the clamping plate 22 rotates to clamp the explosive, one side of the plane of the triangular baffle 238 will contact the inner wall of the limiting groove 222 on the lower surface of the clamping plate 22, allowing The flipping action of the clamping plate 22 stops, thereby limiting the flipping angle of the clamping plate 22 and reducing the force of the clamping plate 22 to clamp the explosive. At this time, the explosive is fixed, and then the bottom plate 21 can be loosened to allow the bottom plate 21 to slowly descend by the weight of the explosive itself. During the installation of the explosive, because the two groups of L plates 33 are pressed in advance to reduce the distance between the L plates 33, one end of the L plate 33 is separated from the inside of the positioning hole 15, thereby adjusting the position of the semicircular block 31, moving the semicircular block 31 to the top of the explosive layer, loosening the L plate 33 to allow one end of the semicircular block 31 to be re-stuck in the inside of the positioning hole 15, when After the position of the semicircular block 31 is fixed, the bottom plate 21 also slowly descends to the top of the semicircular block 31. As the bottom plate 21 is about to descend to the explosive layer, the lower surface of the long plate 244 will contact the outer surface of the semicircular block 31, thereby pushing up the reset plate 241 to make the reset plate 241 rise. When the reset plate 241 rises, the slope B242 and the inclined groove A223 will meet, allowing the clamping plate 22 to rotate in the opposite direction to release the explosive. When the clamping plate 22 rotates in the opposite direction, the other side of the triangular baffle 238 inside the limiting groove 222 will contact the inner wall of the other side of the limiting groove 222, thereby allowing the triangular baffle 238 to rotate in the opposite direction to release the explosive. The plate 238 descends, and finally resets as the clamping plate 22 rotates in the opposite direction, and the triangular baffle 238 is also reset. In the process of both being reset, because the bottom plate 21 continues to descend, and the lower surface of the bottom plate 21 contacts the outer surface of the semicircular block 31, the bottom plate 21 rotates, causing the explosive to slide from the surface of the bottom plate 21 and fall into the explosive layer. At this time, without the gravity of the explosive, the bottom plate 21 will quickly return to the upper end of the barrel 1, and then insert the air spacer, and then wait for the next group of explosives to be placed, so that the integrity of the explosives can be guaranteed when they are placed.
