Description

Technical Field

[0001] This utility model relates to the field of blasting technology, specifically to a blasting device with a directional blasting mechanism. Background Technology

[0002] Directional blasting is a blasting technique that uses the explosive force of explosives to throw earth and rock from a certain area to a designated area and roughly pile them up into the desired shape. It is mainly used for dam construction (water dams or tailings dams), road construction (embankments and roadbeds), and land leveling (industrial sites and farmland construction).

[0003] Utility model patent CN218955583U discloses a blasting device with a directional blasting mechanism, including a base plate. Through holes are formed at the four corners of the upper outer surface of the base plate, and anchor rods are installed in the through holes. A hydraulic telescopic rod is fixedly mounted on the left side of the upper outer surface of the base plate. A mounting plate is provided on the upper part of the hydraulic telescopic rod, and a blasting barrel is provided on the upper part of the mounting plate. A limit support plate is fixedly mounted on the right side of the upper outer surface of the mounting plate, and the left and right sides of the lower outer surface of the blasting barrel are fixedly mounted with… A connecting sheet metal frame is provided, with its lower outer surface fixedly connected to the upper outer surface of the mounting plate. A tilt sensor is located in the middle of the upper outer surface of the mounting plate. A guide rod is located at the lower part of the mounting plate, with fixing blocks fixedly mounted on both ends of the guide rod. One end of each fixing block is fixedly connected to the lower outer surface of the mounting plate. A movable connector is provided between the guide rod and the hydraulic telescopic rod. A rotating connector is provided between the right side of the lower outer surface of the mounting plate and the base plate. When adjustment of the mounting plate 7 is required... When adjusting the angle of the barrel 10, the hydraulic telescopic rod 4 drives the mounting plate 7 and the barrel 10 to rotate along the rotating connector 5, and drives the sliding sleeve 19 to slide along the guide rod 9, thus changing the angle between the barrel 10 and the mounting plate 7. This is more convenient and safer than the manual adjustment by rotating the screw in the prior art. The anchor rod 3 facilitates the connection and fixation between the base plate 1 and the ground, increasing stability. The tilt sensor 12 is installed with its axis A parallel to the axis B on the mounting plate 7, facilitating the monitoring of the elevation angle between the mounting plate 7 and the barrel 10. This is more convenient and accurate than the observation scale in the prior art. In this patent, the tilt angle of the barrel is adjusted by the hydraulic telescopic rod. Since the hydraulic telescopic rod, the barrel, and the base plate form a triangular structure, the tilt angle adjustment of the barrel is limited by the hydraulic telescopic rod and can only be adjusted within a single plane of the triangular structure. This restricts the orientation and tilt angle adjustment of the barrel in directional blasting. Utility Model Content

[0037] Preferably, two sets of first locking screw holes 602 and second locking studs 701 are provided to enhance the friction between the first locking stud 601 and the second fixing ring 11, thereby fixing the position of the first fixing ring 402 relative to the second fixing ring 11.

[0038] In the above configuration, by rotating the first circumferential adjusting sleeve 401, the first circumferential adjusting sleeve 401 rotates circumferentially along the axis of the support column 3. With the cooperation of the first marking line 12 and the first angle scale 13, the rotation angle of the first circumferential adjusting sleeve 401 can be controlled. After the rotation angle of the first axis adjusting sleeve is determined, the first locking stud 601 is rotated to move down and abut against the second fixing ring 11, thereby fixing the position of the first circumferential adjusting sleeve 401 relative to the second fixing ring 11.

[0039] Further, see Figure 2 , 3 The second circumferential adjusting component 5 includes a second circumferential adjusting rod 501 and a third fixing ring 502 disposed on the second circumferential adjusting rod 501.

[0041] Preferably, the outer diameter of the fourth fixing ring 18 is larger than the outer diameter of the third fixing ring 502.

[0042] Further, see Figure 2 , 3 The second locking member 7 includes a second locking stud 701 movably disposed on the third fixing ring 502. The second locking stud 701 moves toward the fourth fixing ring 18 under the action of external force and abuts against the fourth fixing ring 18 to fix the position of the third fixing ring 502 relative to the fourth fixing ring 18.

[0043] Preferably, the third fixing ring 502 is provided with a second locking screw hole 702, and the second locking stud 701 is threadedly connected to the second locking screw hole 702.

[0044] Preferably, two sets of second locking screw holes 702 and second locking studs 701 are provided to enhance the friction between the second locking studs 701 and the fourth fixing ring 18, thereby fixing the position of the third fixing ring 502 relative to the fourth fixing ring 18.

[0045] In the above configuration, by rotating the second circumferential adjusting rod 501 along its own axis, the second rotating column 20 is driven to rotate within the second rotating hole 21, and the third fixing ring 502 rotates on the surface of the fourth fixing ring 18. The position of the second circumferential adjusting rod 501 is determined according to the second marking line 17 and the second angle scale 19. The position of the clamping member 10 connected to the second circumferential adjusting rod 501 relative to the support column 3 can be adjusted, thereby adjusting the clamping member 10 from a vertical state to a horizontal state. The angle of the clamping member 10 relative to the horizontal plane can be adjusted by rotating the second circumferential adjusting rod 501. After the position of the second circumferential adjusting rod 501 is determined, the second locking stud 701 is rotated to abut against the fourth fixing ring 18 to fix the position of the second circumferential adjusting rod 501.

[0046] Further, see Figure 2 , 4The third circumferential adjusting component 8 includes a third circumferential adjusting rod 801 rotatably connected to the second circumferential adjusting rod 501, and a fifth fixing ring 802 disposed on the third circumferential adjusting rod 801. Under the action of external force, the third circumferential adjusting rod 801 rotates circumferentially along the connection point with the second circumferential adjusting rod 501 so that the third circumferential adjusting rod 801 is coaxial with the second circumferential adjusting rod 501 or perpendicular to each other. The fifth fixing ring 802 is provided with a third marking line 23, and the second axial adjusting rod is provided with a sixth fixing ring 24. The sixth fixing ring 24 is clearance-fitted with the fifth fixing ring 802, and the sixth fixing ring 24 is provided with a third angle scale 25.

[0047] Preferably, the end of the second circumferential adjusting rod 501 is provided with a "U"-shaped rotating head 26, the rotating head 26 is provided with a rotating shaft 27, the rotating shaft 27 is set vertically downward, and the third circumferential adjusting rod 801 is provided with a rotating sleeve 28 that is rotatably connected to the rotating shaft 27.

[0049] Preferably, the outer diameter of the sixth fixing ring 24 is greater than the outer diameter of the fifth fixing ring 802.

[0050] Further, see Figure 4 The third locking member 9 includes a third locking stud 901 movably disposed on the fifth fixing ring 802. The third locking stud 901 moves toward the sixth fixing ring 24 under the action of external force and abuts against the sixth fixing ring 24 to fix the position of the fifth fixing ring 802 relative to the sixth fixing ring 24.

[0051] Preferably, the fifth fixing ring 802 is provided with a third locking screw hole 902, and the third locking stud 901 is threadedly connected to the third locking screw hole 902.

[0052] Preferably, two sets of third locking screw holes 902 and third locking studs 901 are provided to enhance the friction between the third locking studs 901 and the sixth fixing ring 24, thereby fixing the position of the fifth fixing ring 802 relative to the sixth fixing ring 24.

[0053] In the above configuration, rotating the third circumferential adjusting rod 801 along the rotating shaft 27 can adjust the position of the clamp relative to the support column 3 in the circumferential direction. The rotation angle of the third circumferential adjusting rod 801 is controlled by the third marking line 23 and the third angle scale 25. After the position of the third circumferential adjusting rod 801 is determined, the third locking stud 901 is rotated to abut against the sixth fixing ring 24, thereby fixing the position of the third circumferential adjusting rod 801.

[0054] Further, see Figure 2The clamping member 10 includes a clamping sleeve 1001 located at the end of the third circumferential adjusting rod 801 and a clamping screw 1102 disposed in the clamping sleeve 1001. The clamping screw 1102 moves toward the clamping sleeve 1001 under the action of external force, thereby fixing the external gun barrel in the clamping sleeve 1001.

[0055] Preferably, the clamping sleeve 1001 has a "U" shaped structure, the bottom end of the clamping sleeve 1001 is provided with a support plate 29, the clamping sleeve 1001 is provided with a clamping screw hole 30, and the clamping screw 1102 is connected to the clamping screw hole 30 by a thread.

[0056] In the above configuration, the gun barrel is placed inside the clamping sleeve 1001. By rotating the clamping screw 1102 to abut against the gun barrel, the gun barrel can be fixed inside the clamping sleeve 1001. To ensure that the gun barrel is located in the middle of the clamping sleeve 1001, the clamping screw 1102 can be arranged opposite to each other on both sides of the clamping sleeve 1001. By having two sets of oppositely arranged clamping screws 1102 abut against both sides of the gun barrel, the gun barrel can be fixed in the middle of the clamping sleeve 1001.

[0057] In this embodiment, after the entire device is fixed to the ground by the fixing rod 201 and the supporting base plate, the height of the supporting column 3 can be adjusted to adjust the height of the clamping sleeve 1001, thereby adjusting the height of the gun barrel. By rotating the first circumferential rotating sleeve, the clamping sleeve 1001 can be adjusted to rotate circumferentially along the supporting column 3. By rotating the second circumferential adjusting rod 501, the clamping sleeve 1001 can be adjusted to rotate circumferentially along the axis of the second circumferential adjusting rod 501. At this time, the clamping sleeve 1001 can be adjusted from a vertical state to a horizontal state, that is, the angle between the clamping sleeve 1001 and the horizontal plane can be adjusted. The angle adjustment range is 0°-90°. By adjusting the third circumferential adjusting rod 801 to rotate along the rotating shaft 27, the clamping sleeve 1001 can be adjusted to rotate along the rotating shaft 27, that is, the clamping sleeve 1001 can be adjusted to rotate circumferentially relative to the axis of the supporting column 3 (the rotating shaft 27 is set parallel to the supporting column 3).

[0058] For example, a reference circle is formed by drawing a circle with the support column 3 as the center and the second circumferential adjusting rod 501 as the radius. During the adjustment of the clamping sleeve 1001, when the first circumferential adjusting sleeve 401 is rotated, the clamping sleeve 1001 rotates on the reference circle, facing different directions. When the second circumferential adjusting rod 501 is rotated, the position of the clamping sleeve 1001 on the reference circle is not fixed, and it only rotates circumferentially along the axis of the second circumferential adjusting rod 501 to adjust the angle of the clamping sleeve 1001 relative to the horizontal plane. When the clamping sleeve 1001 is directly rotated along the rotating shaft 27, the clamping sleeve 1001 rotates with the rotating shaft 27 as the center, and the position of the clamping sleeve 1001 relative to the reference circle changes, thereby adjusting the orientation and inclination angle of the gun barrel inside the clamping sleeve 1001.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
