Description

Technical Field

[0001] The utility model belongs to the technical field of concentrated energy blasting, in particular to a bidirectional concentrated energy blasting device. Background Art

[0002] Focused charge blasting is a controlled blasting technology that can use a focused charge device to concentrate the impact of conventional blasting on the hole wall locally, thereby increasing the effect of local destructive action and better achieving the effect of controlled blasting.

[0003] At present, the commonly used circular energy-gathering tube is an integral form, and the general tube length is 1500mm. It is inconvenient when charging is required, and it is even more inconvenient to connect the detonator. In addition, the leg line needs to be placed outside the energy-gathering tube. When the energy-gathering tube is pushed to the pre-drilled blasthole, it is easy to rub against the wall of the blasthole and the leg line is easy to tear off. Moreover, after the charging is completed, even if the two ends of the energy-gathering tube are blocked, due to the several through holes opened on the surface of the energy-gathering tube, the top of the energy-gathering tube body cannot be fully sealed, resulting in the hidden danger of moisture in the explosives. Therefore, it is of great significance to study a new bidirectional energy-gathering blasting device to solve the above problems. Utility Model Content

The energy-gathering tube 1 is composed of two semi-ring bodies 11. By separating the two semi-ring bodies 11 of the energy-gathering tube 1, the two semi-ring bodies 11 can be combined to form the energy-gathering tube 1. When the two semi-ring bodies 11 are separated, it is convenient to place the blasting charge. After the energy-gathering tube 1 is separated into the two semi-ring bodies 11, it is also convenient to place the detonator and the detonator connection line, so that the foot line can be smoothly placed in the energy-gathering tube 1, avoiding the problem that the foot line is easily torn off due to friction with the hole wall of the blast hole, which affects the blasting. Grooves 12 are provided on the upper and lower sides of the semi-ring body 11, and the grooves 12 are engaged with the protruding rods 23, so that the two semi-ring bodies 11 can be reinforced and connected, so as to avoid the blasting shock wave from rushing out from between the two semi-ring bodies 11 in advance;

[0029] The two end surfaces of the semi-ring body 11 are provided with cutouts 16, which are located at the positions of the two inclined surfaces 13. Two fixing rings 15 are fixedly connected to one side of the semi-ring body 11 and located between the two inclined surfaces 13, and the two semi-ring bodies 11 are connected by a retaining structure 2. The retaining structure 2 includes two transverse edges 21, which are arranged on the upper and lower sides of the energy-gathering tube 1, and a protruding rod 23 is fixedly connected between the two transverse edges 21, and the protruding rod 23 is embedded in the groove 12.

The two transverse plates 4 are fixedly connected to the inside of the three annular strips 22. By moving the position of the transverse plates 4, the transverse plates 4 can drive the energy-gathering openings 5 ​​to be staggered with the energy-gathering holes 14, so that the energy-gathering tube 1 can be closed to avoid the problem of the blasting charge being affected by moisture. When adjusting the position of the transverse edges 21, the position of the transverse plates 4 can be adjusted so that the transverse plates 4 drive the energy-gathering openings 5 ​​to correspond to the energy-gathering holes 14, so that a smooth blasting operation can be maintained. Two transverse plates 4 are connected to the retaining structure 2. A plurality of energy-gathering openings 5 ​​are provided on the transverse plates 4. The plurality of energy-gathering openings 5 ​​are staggered with the plurality of energy-gathering holes 14, respectively.

Two inclined surfaces 13 are provided on one side of the semi-ring body 11, and the transverse plate 4 is provided between the two inclined surfaces 13.

[0030] The working principle of the utility model is as follows: when assembling, blasting charges are placed in the semi-ring body 11, and detonators and detonator connecting lines are laid. After laying, the semi-ring bodies 11 are assembled again, and the annular strip 22 is sleeved on the energy-gathering tube 1, so that the transverse plate 4 is located between the notches formed by the two inclined surfaces 13, and the position of the annular strip 22 is locked by screwing the fixing ring 15 with the bolt 25, and the joint 31 is docked with the energy-gathering tube 1, so that the fitting 32 penetrates the cutout 16 and fits with the inclined surface 13;

[0031] When the blasting charge is detonated, the blasting stress wave and the explosive energy of the explosive gas are first released from the energy-gathering holes 14 and the energy-gathering ports 5, forming a high-speed energy flow and generating a gas wedge effect, thereby generating a tensile force in the direction perpendicular to the initial crack and causing tensile stress concentration, causing the rock mass to become unstable and fracture along the pre-crack direction, and increasing the tensile stress through multiple energy-gathering holes 14 and the energy-gathering ports 5, forming a roughly connected fracture surface, and secondly, achieving the purpose of bidirectional blasting.
