DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.
[0025] As Figures 1-4 shown, the device for shaped charge blasting according to an embodiment of the present invention includes a body 1 and a clamping assembly 2. The body 1 can move in a roadway, and the inner wall surface of the roadway has a drilling hole. The clamping assembly 2 includes a limiting member 21 and a clamping member 22. The limiting member 21 is provided on the body 1, and the limiting member 21 has a limiting hole 211. A slotted head 3 is inserted into the limiting hole 211, and the slotted head 3 is used for cutting a slot on the inner wall surface of the drilling hole. The clamping member 22 is provided on the body 1 and is located below the limiting member 21. The clamping member 22 can move along the central axis direction of the limiting hole 211 relative to the body 1. The clamping member 22 has a clamping hole 221, and an extension section 4 is inserted into the clamping hole 221. The clamping member 22 can clamp the extension section 4 and move it towards the slotted head 3 and install the extension section 4 on the slotted head 3.
[0026] The device for energy - focused blasting according to the embodiment of the present utility model installs the extension section 4 on the slotted head 3 through the clamping member 22. The operation is simple. The installation of the extension section 4 reduces the distance between the slotted head 3 and the inner wall surface of the roadway, facilitating the slotted head 3 to extend into the drill hole, constructing the drill hole into a "shaped charge tube". The slotted head 3 cuts slots on the inner wall surface of the drill hole, eliminating the use of the shaped charge tube, saving costs, increasing the charge amount under the condition of unchanged hole diameter, enhancing the blasting power, enabling the increase of the distance between adjacent drill holes, reducing the drill hole construction volume, and saving construction costs and construction time.
[0027] Specifically, the central axes of the clamping holes 221 and the limiting holes 211 coincide to improve the accuracy of the cooperation between the extension section 4 and the slotted head 3.
[0028] In some embodiments, the extension section 4 is thread - connected to the slotted head 3.
[0029] Specifically, the inner peripheral surface at the lower end of the slotted head 3 has internal threads, and the outer peripheral surface at the upper end of the extension section 4 has external threads. The lower end of the slotted head 3 is thread - connected to the upper end of the extension section 4. The connection method is simple and firm. It can be understood that connecting the extension section 4 at the lower end of the slotted head 3 can shorten the distance between the slotted head 3 and the inner wall surface of the roadway. Therefore, the number of extension sections 4 can be selected according to the distance between the slotted head 3 and the inner wall surface of the roadway, and the extension sections 4 are also thread - connected to each other.
[0030] In some embodiments, the device for energy - focused blasting and hole - forming according to the embodiment of the present utility model further includes a nitrogen - making system 51, a hydraulic system 52, and a control system 53. Each system is connected to the required device through hydraulic pipelines.
[0031] In some embodiments, the clamping assembly 2 further includes a guiding member 23. The guiding member 23 is arranged on the body 1 and is rotatable relative to the body 1. The rotation angle of the guiding member 23 is a, where 0 < a < 180°. The limiting member 21 is arranged at the upper end of the guiding member 23, and the clamping member 22 is arranged at the lower end of the guiding member 23 and can slide on the guiding member 23.
[0032] Specifically, the guiding member 23 can rotate relative to the body 1 between 0 and 180° to drive the limiting member 21 and the clamping member 22 to rotate, thereby adjusting the direction of the slotted head 3 to align the slotted head 3 with the drill hole, facilitating the slotted head 3 to cut slots in the drill hole.
[0033] In some embodiments, the clamping assembly 2 further includes a guiding rod 24 and a control member 25. The guiding rod 24 is arranged on the guiding member 23. The guiding rod 24 can rotate together with the guiding member 23. The lower end of the guiding rod 24 extends out of the lower end of the guiding member 23. The control member 25 is slidably installed on the guiding rod 24 and is located below the clamping member 22. The control member 25 can push the extension section 4 to move towards the slotted head 3.
[0034] Specifically, when the control member 25 pushes the extension section 4 to move, the clamping member 22 can limit the position of the extension section 4, ensuring that the extension section 4 remains stable during movement and is not prone to deviation.
[0035] In some embodiments, the device for cumulative blasting further includes a mounting assembly 6. The mounting assembly 6 includes a rotating member 61. The rotating member 61 is detachably provided on the top surface of the control member 25 and is rotatable relative to the control member 25. The rotating member 61 is engaged with the lower end of the extension section 4 in a clamping manner, and the rotating member 61 can drive the extension section 4 to rotate.
[0036] Specifically, during installation, the slotted head 3 is clamped in the limiting hole 211, the extension section 4 is arranged in the clamping hole 221, the control member 25 moves axially along the guide rod 24 to push the extension section 4 towards the slotted head 3, and the clamping member 22 also moves along with the extension section 4. The control member 25 controls the rotation of the rotating member 61 so that the upper end of the extension section 4 is threadedly connected to the lower end of the slotted head 3.
[0037] It can be understood that during the slotting process, the extension section 4 and the slotted head 3 as a whole can be rotated around the central axis of the clamping hole 221 through the rotating member 61 to drive the slotted head 3 to rotate, so that the crack generated by the slotted head 3 is consistent with the pre-cracking direction of the drill hole, improving the slotting effect.
[0038] In some embodiments, the mounting assembly 6 further includes a pneumatic hammer 62. The pneumatic hammer 62 is arranged in the inner cavity of the control member 25, and the piston of the pneumatic hammer 62 can extend out from the top surface of the control member 25 to push the extension section 4 and the slotted head 3 as a whole to move.
[0039] Specifically, after the extension section 4 is installed on the slotted head 3, the rotating member 61 is removed from the control member 25, so that the piston of the pneumatic hammer 62 is exposed from the top surface of the control member 25. The distance between the piston rod and the lower end of the last extension section 4 is about 10 cm. The piston rod of the pneumatic hammer 62 can impact the lower end of the extension section 4 within the movement range to drive the extension section 4 and the clamping member 22 to move in the extending direction of the guide rail, so that the slotted head 3 cuts a slot on the inner wall surface of the drill hole. By gradually advancing the pneumatic hammer 62, the slotted head 3 cuts a slot in the drill hole. A protective cover (not shown) is provided on the piston rod to protect the piston rod from being easily damaged.
[0040] In some embodiments, the slotted head 3 includes a guiding portion 31, a positioning portion 32, and a slotting portion 33. The guiding portion 31 is arranged at the upper end of the positioning portion 32, and the slotting portion 33 is arranged on the outer peripheral surface of the positioning portion 32 and extends along the extending direction of the positioning portion 32. The slotting portion 33 is used for cutting a slot on the inner wall surface of the drill hole.
[0041] Specifically, the positioning portion 32 is cylindrical, and the inner wall surface at the lower end of the positioning portion 32 has an internal thread, so that the positioning portion 32 can be threadedly connected to the extension section 4. The guiding portion 31 is frustum-shaped, and the area of the upper end of the guiding portion 31 is smaller than the area of the lower end of the guiding portion 31. The lower end of the guiding portion 31 is fixedly connected to the upper end of the positioning portion 32, and the cross-sectional area of the lower end of the guiding portion 31 is the same as the cross-sectional area of the positioning portion 32. The slotted portion 33 is provided on the outer peripheral surface of the positioning portion 32 and extends along the extending direction of the positioning portion 32. The cross-sectional area of the slotted portion 33 is generally triangular, so as to facilitate slitting the inner wall surface of the drill hole. There are two slotted portions 33, and the two slotted portions 33 are arranged at intervals on the outer peripheral surface of the positioning portion 32.
[0042] In some embodiments, the top surface of the guiding portion 31 has an air outlet hole 311. The air outlet hole 311 communicates with the guiding portion 31, the positioning portion 32 and the extension section 4. The air outlet hole 311 is used to introduce nitrogen into the drill hole to prevent gas from accumulating in the drill hole and ensure construction safety.
[0043] In some embodiments, the device for shaped charge blasting further includes an alignment member 71. The alignment member 71 is provided on the main body 1, and the alignment member 71 is connected to the guiding member 23 to drive the guiding member 23 to rotate.
[0044] Specifically, at least a part of the alignment member 71 can rotate in the Y-Z plane. The guiding member 23 is connected to at least a part of the alignment member 71, so that the connecting member can also rotate in the Y-Z plane, making the implementation method of the rotation of the guiding member 23 simple and easy to operate.
[0045] In some embodiments, the device for shaped charge blasting further includes a moving member 72 and a supporting member 73. The moving member 72 is provided on the bottom surface of the main body 1, and the moving member 72 is used to drive the main body 1 to move in the roadway. The supporting member 73 is detachably installed on the main body 1. One end of the supporting member 73 passes through the main body 1 and supports on the bottom surface of the roadway, and the other end of the supporting member 73 supports on the top surface of the roadway.
[0046] Specifically, the moving member 72 is provided on the bottom surface of the main body 1, and the moving member 72 can move in the roadway to drive the main body 1 to move in the roadway. The supporting member 73 includes columns 731. There are four columns 731, and the four columns 731 are respectively arranged at the four corner positions of the main body 1. The columns 731 extend in the up-down direction. The lower ends of the columns 731 support on the bottom surface of the roadway, and the upper ends of the columns 731 support on the top surface of the roadway.
[0047] Specifically, the vertical column 731 can be telescopically extended and retracted in the vertical direction to adapt to roadways of different heights, thereby improving applicability. A support cap 732 is provided at the upper end of the vertical column 731. The cross-sectional area of the support cap 732 is larger than that of the vertical column 731 to increase the contact area between the vertical column 731 and the top surface of the roadway. A plug-in member 733 is provided on the side of the support cap 732 close to the roadway. The plug-in member 733 can be inserted into the top surface of the roadway to enhance the support of the vertical column 731 on the top surface of the roadway.
