Description

Technical Field

[0001] The utility model relates to the technical field of blasting equipment production, and particularly relates to a combined small - charge initiator anti - sympathetic detonation device. Background Art

[0002] In recent years, with the continuous development and progress of blasting technology, various initiators have been widely used in earth - rock excavation, urban demolition and oil - gas exploitation industries. As a key product in the blasting field, the production process of initiators is much more complex than that of ordinary explosive products. Due to the high sensitivity of initiators, the protection costs during production, turnover and storage are extremely high, and the safety risks are relatively large. Once a single initiator explodes accidentally, it is very easy to cause sympathetic detonation of multiple products, resulting in serious consequences. At present, most of the initiator anti - sympathetic detonation devices developed in China are aimed at the production link, and cannot effectively prevent the accidental sympathetic detonation of sensitive initiators and their semi - finished products during the turnover process and temporary storage process.

[0003] Traditional turnover trays have no explosion - resistant performance. Once a single initiator explodes accidentally, the entire turnover tray will disintegrate, and other products are also likely to undergo sympathetic detonation or fly away, causing great potential safety hazards.

[0004] Traditional initiators are placed in a turnover tray and directly transported through the turnover tray. During transportation, they are very likely to fall and explode accidentally. Content of the Utility Model

[0005] Aiming at the technical problems existing in the background art, the purpose of the utility model is to provide a combined small - charge initiator anti - sympathetic detonation device, which is convenient for transporting multiple initiators and preventing sympathetic detonation during transportation.

[0006] To achieve the above - mentioned purpose, the technical solution provided by the utility model is as follows:

[0007] A combined small - charge initiator anti - sympathetic detonation device includes a support box and a support member detachably arranged in the support box. The interior of the support box is provided with a number of partition rooms. Both sides of the partition rooms are provided with a number of grooves. The support member is detachably arranged in the partition rooms. The support member includes a turnover tray and a clamping plate. Both sides of the clamping plate are provided with convex blocks. One end of the turnover tray is provided with a number of holes. The two sides of the clamping plate and the turnover tray are connected in the grooves. The turnover tray is arranged above the clamping plate, and the bottom of the turnover tray abuts against the convex blocks.

[0008] Preferably, a sealing ring is arranged at one end of the support box.

[0009] Preferably, a hinge is arranged on one side of the support box, and a box door is connected to the hinge. When the box door closes the support box, the sealing ring and the box door are in close contact.

[0010] Preferably, an L-shaped baffle is provided on the box door, and a rotating block is rotatably provided on the support box. When the box door is in close contact with the sealing ring, the rotating block is clamped with the baffle.

[0011] Preferably, a plurality of through holes are provided at one end of the support box, and the through holes penetrate the support box and enter the partition room.

[0012] Preferably, a connecting member is provided on the turnover tray. The connecting member includes a connecting plate. A plurality of connecting holes are provided on the connecting plate. The connecting holes are aligned with the holes. A plurality of rotating grooves are provided inside the connecting plate, and the rotating grooves are provided at the positions of the connecting holes.

[0013] Preferably, a limiting groove is provided at one end of the connecting plate. The limiting groove penetrates one end of the connecting plate and extends into the rotating groove. A limiting block is detachably provided on the connecting plate. The shape of the limiting block is the same as that of the limiting groove, and the limiting block extends into the rotating groove from the position of the limiting groove.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0026] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0027] Embodiment

[0028] As Figures 1-7 shown, a combined small - charge initiator anti - sympathetic explosion device includes a support box 1 and a support member detachably arranged in the support box 1. A number of partition chambers 2 are arranged inside the support box 1. A number of grooves 21 are arranged on both sides of the partition chamber 2. The support member is detachably arranged in the partition chamber 2. A sealing ring 3 is arranged at one end of the support box 1. A hinge 41 is arranged on one side of the support box 1. A box door 4 is connected to the hinge 41. When the box door 4 closes the support box 1, the sealing ring 3 and the box door 4 are in close contact. When the initiator is placed in the support box 1, the sealing ring 3 can isolate air to prevent the internal initiator from being affected by moisture. A number of support boxes 1 are fixed on a frame body 5. A runner 51 is arranged below the frame body 5. The initiator is placed in the support box 1. By pushing the frame body 5, the runner 51 can drive the anti - sympathetic explosion device to move, and a large number of initiators can be transported.

[0029] AsFigures 1-3 As shown in the figure, an L-shaped baffle 42 is provided on the box door 4, and a rotating block 101 is rotatably provided on the support box 1. When the box door 4 and the sealing ring 3 are in close contact, the rotating block 101 and the baffle 42 are clamped. The support box 1 and the box door 4 are connected by the rotating block 101 and the baffle 42 to prevent the box door 4 from opening during the transportation of explosive materials. A number of through holes 22 are provided at one end of the support box 1, and the through holes 22 penetrate the support box 1 and enter the partition 2. When the explosive materials are placed in the support box 1, a rubber plug is inserted into the through holes 22 to block the through holes 22, preventing the explosive materials from getting damp. At the same time, when a single explosive material explodes inside, the air pressure inside the support box 1 rises. At this time, the rubber plug is impacted by the explosion pressure and disengages from the through holes 22, reducing the air pressure inside the support box 1 and preventing excessive pressure during internal explosion, thereby avoiding the occurrence of sympathetic detonation.

[0030] As Figures 1-7 shown in the figure, the support member includes a turnover tray 7 and a clamping plate 6. Convex blocks 61 are provided on both sides of the clamping plate 6. A number of holes 71 are provided at one end of the turnover tray 7. The explosive materials are placed in the holes 71. Both sides of the clamping plate 6 and the turnover tray 7 are connected in the groove 21. The turnover tray 7 is arranged above the clamping plate 6, and the bottom of the turnover tray 7 abuts against the convex blocks 61. There is a gap between the turnover tray 7 and the clamping plate 6, and the gap position can play a buffering effect to prevent the explosion impact force from damaging the structure of the turnover tray 7 when the internal explosive materials explode. A connecting member is provided on the turnover tray 7. The connecting member includes a connecting plate 8. A number of connecting holes 81 are provided on the connecting plate 8. The connecting holes 81 are aligned with the holes 71. A number of rotating grooves 83 are provided inside the connecting plate 8. The rotating grooves 83 are arranged at the positions of the connecting holes 81. A limiting groove 82 is provided at one end of the connecting plate 8. The limiting groove 82 penetrates one end of the connecting plate 8 into the rotating groove 83. A limiting block 9 is detachably provided on the connecting plate 8. The shape of the limiting block 9 is the same as the shape of the limiting groove 82. When the explosive materials are placed on the turnover tray 7, the connecting plate 8 and the turnover tray 7 are closely attached. The limiting block 9 extends into the rotating groove 83 from the position of the limiting groove 82. The limiting block 9 blocks the holes 71 and is in close contact with the explosive materials to prevent the explosive materials from colliding with the clamping plate 6 during transportation, thereby avoiding the occurrence of explosion. At the same time, the limiting block 9 can rotate in the rotating groove 83 during transportation. The limiting block 9 can only enter and exit from the position of the limiting groove 82, and the limiting block 9 will not disengage from the limiting groove 82 during transportation, greatly ensuring the stability of the explosion-proof function.

[0031] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
