Description

Technical Field

[0001] The present invention relates to a flat - structure array - type initiation platform, belonging to the technical field of initiation platforms. Background Art

[0002] In some mechanical studies, it is often necessary to simultaneously apply an impact load to the surface of an object. Currently, the commonly used technical means is to arrange some explosives in an array on the object surface according to requirements, and to achieve the effect of synchronous initiation as much as possible by strictly controlling the initiation time of these explosive arrays.

[0003] The disadvantage of this method is that if the area of a single charge in the array is small, it is difficult to effectively simulate the action of the entire surface under a synchronous impact load, which is equivalent to changing a plane into a set of points densely distributed on this plane. At the same time, the requirement for the synchronism of the initiation system is extremely high, and it is difficult to achieve precise synchronous initiation. If the area of a single charge in the array is enlarged, that is, many densely distributed circles or other shapes are used to replace the entire plane, it is difficult to ignore the process of explosive explosion spreading from the initiation point to the adjacent position within a single charge, and synchronous initiation cannot be achieved within a single charge. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a flat - structure array - type initiation platform that forms different wire arrays for flash synchronous initiation for different experimental specimens.

[0005] To achieve the above - mentioned purpose, the technical solution proposed by the present invention is: a flat - structure array - type initiation platform, including an upper platform, a lower platform, a bracket connecting the upper and lower platforms, a plurality of radial slide rails slidably connected to the upper and lower platforms, and a plurality of metal wires slidably connected to the radial slide rails. Both ends of each metal wire are respectively connected to the radial slide rails on the upper and lower platforms; by adjusting the positions of the plurality of radial slide rails on the upper and lower platforms, the plurality of metal wires form an array arrangement.

[0006] A further design of the above - mentioned technical solution is: optical axis guide rails are respectively provided on the upper and lower platforms, and the radial guide rails are slidably connected to the optical axis guide rails.

[0007] At least two optical axis guide rails are provided on both the upper and lower platforms, and the optical axis guide rails are arranged on opposite sides of the upper and lower platforms.

[0008] Both ends of the optical axis guide rail are fixedly connected to the upper and lower platforms through fixing seats. Through holes are provided on the fixing seats, and the optical axis guide rail passes through the through holes and is fixedly connected to the fixing seats.

[0009] The at least two optical axis guides are arranged parallel to each other. The radial slide rail is connected to the optical axis guide on the upper or lower platform and is arranged perpendicular to it. The radial slide rail can be slidably connected to the optical axis guide in a direction parallel or perpendicular to the optical axis guide.

[0010] The radial slide rail is slidably connected to the optical axis guide through a connecting block. The connecting block is provided with two through holes arranged perpendicular to each other. Threaded holes communicating with the corresponding through holes are provided on one side of the two through holes, and locking bolts are screwed in the threaded holes. The radial slide rail and the optical axis guide are respectively slidably connected in the two through holes and are fixed by the bolts in the corresponding threaded holes.

[0011] A wire seat is provided on the radial slide rail, and one end of the metal wire is connected to the wire seat.

[0012] The wire seat includes a slider, a locking screw, a terminal block, and a locking nut. The slider is provided with a through hole. A threaded hole communicating with the through hole is provided on one side of the slider. The radial slide rail is inserted into the through hole and is slidably connected to the through hole. The locking screw is screwed into the threaded hole and one end can abut against the radial slide rail. The terminal block is arranged on the slider and has an external thread at one end. The metal wire is connected to the terminal block and is fixed to the terminal block by screwing the locking nut onto the external thread.

[0013] The upper and lower platforms are connected to the bracket through L-shaped steel. Both sides of the L-shaped steel are provided with elongated holes. The upper and lower platforms are provided with through holes at corresponding positions, and the bracket is provided with elongated holes at corresponding positions. The L-shaped steel is fixed to the upper and lower platforms by sequentially passing bolts through the elongated holes on one side and the through holes on the upper / lower platforms and then screwing nuts, and is fixed to the bracket by sequentially passing bolts through the elongated holes on one side and screwing nuts in the elongated holes on the bracket.

[0014] A base is provided at the bottom of the lower platform, and the lower platform is fixedly connected to the base.

The two sides of the L - shaped steel 4 are respectively connected to the upper and lower platforms and the bracket 3, so as to fixedly connect the bracket 3 to the lower platform.

[0027] The upper and lower platforms are provided with optical axis guides 5 on the opposite sides. There are two mutually parallel optical axis guides 5 on the upper and lower platforms respectively. Fixed seats 51 are fixed at both ends of the optical axis guides 5. Through holes are provided on the fixed seats 51. The optical axis guides 5 are inserted into the through holes and fixedly connected to the fixed seats 51. The fixed seats 51 are fixed on the upper or lower platform.

[0028] A plurality of radial sliding rails 6 are slidably connected to the two optical axis guides 5 located on the upper or lower platform. Each radial sliding rail 6 is slidably connected to the two optical axis guides 5 and is perpendicularly arranged to the two optical axis guides 5. Two connecting blocks 61 are slidably connected to the radial sliding rail. As Figure 4 shown, two mutually perpendicular through holes 611 are provided on the connecting block 61. Threaded holes 612 communicating with the corresponding through holes are provided on one side of the two through holes 611.

[0031] The array detonating platform of this embodiment can place the target item 9 in the shape of a frustum of a cone at the opening of the "U"-shaped platform. Spray photosensitive explosive on the target item 9, and then adjust the position and length of the metal wire 7 through the radial guide rail 6 and the wire seat 71, so that a plurality of metal wires 7 form an array shape matching the surface of the target item 9. By passing a high-voltage current through the metal wire 7, the metal wire 7 emits extremely strong light, and synchronously detonates the photosensitive explosive on the surface of the target item 9. When the surface of the target item 9 is irregular, the array of metal wires 7 can also be adjusted to ensure that the surface of the target item 9 receives strong light irradiation at the same time, achieving the purpose of synchronous detonation.
