Description

Technical Field

[0001] The present invention relates to the technical field of engineering blasting, in particular to a propulsion-type deep hole blasting interval charging device and a use method thereof. Background Art

[0002] Drilling and blasting is a common method used in bridge demolition projects. Its efficiency and speed make it widely adopted in many demolition projects. However, the continuous charging method often used in actual projects, while simple to operate, has many drawbacks.

[0003] (1) The continuous charging method relatively concentrates the charge in the blasthole, resulting in a concentrated energy distribution. After the explosives are detonated, the impact force on the rock at the bottom and top of the blasthole is significantly different. This uneven impact force results in uneven crushing effect. This uneven crushing effect not only greatly increases the difficulty of cleaning up the subsequent blasted rock, but also significantly increases the workload of secondary crushing, seriously affecting the efficiency of the project.

[0004] (2) Continuous charging releases a large amount of explosive energy in a concentrated manner. This, on the one hand, causes strong blasting vibrations, adversely affecting surrounding structures; on the other hand, it significantly increases the initial velocity of flying rocks, extending their projection distance and requiring a larger warning area, increasing the cost and difficulty of safety management.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Reference Figures 1-6 The present invention provides a push-type deep hole blasting interval charging device, comprising:

[0040] The support mechanism includes a support 1, a slide groove 2 is provided on the support 1, a push tube 3 is slidably fitted in the slide groove 2, and a plurality of through holes 4 are provided along the sliding direction of the push tube 3, and a cartridge tube filled with explosives is hung on the push tube 3 through the through holes 4;

[0041] The positioning mechanism includes a first groove 5 formed in the side wall of the slide 2. A wedge-shaped positioning block 6 is slidably fitted in the first groove 5. A first spring 7 is fixedly connected between the wedge-shaped positioning block 6 and the first groove 5. The axis of the first spring 7 is perpendicular to the sliding direction of the push tube 3. When any through hole 4 is aligned with the wedge-shaped positioning block 6, the first spring 7 pushes the wedge-shaped positioning block 6 into the through hole 4, and the inclined surface of the wedge-shaped positioning block 6 abuts against the wall of the through hole 4.

[0042] The propulsion mechanism 8 is arranged on the support 1. When the propulsion mechanism 8 drives the push tube 3 to slide along the slide groove 2 and propel it into the blast hole, the hole wall of the through hole 4 squeezes the wedge-shaped positioning block 6 to retract into the first groove 5.

[0043] Furthermore, the top wall of the through hole 4 has a slope on one side close to the wedge-shaped positioning block 6, which is adapted to the slope of the wedge-shaped positioning block 6. When the wedge-shaped positioning block 6 extends into the through hole 4, the top slope of the through hole 4 is against the slope of the wedge-shaped positioning block 6.

[0044] Furthermore, two vertical grooves are opened on the side wall of the push tube 3 near the chute 2, so that when the push tube 3 is placed in the chute 2, there is a gap between the side wall part of the push tube 3 with the vertical groove and the chute 2, and the connecting line on the medicine tube can be passed through the vertical groove, and the two ends of the connecting line pass through the two adjacent through holes 4 to realize the binding connection of the medicine tube; or a hook is installed on the medicine tube and the hook is hooked on the through hole 4.

[0045] Furthermore, the width of the wedge-shaped positioning block 6 is smaller than the width of the through hole 4, and the wedge-shaped positioning block 6 is located between the two vertical grooves. When one push tube 3 is pushed and another push tube 3 is connected, the two cable ties are passed through the through holes 4 of the two push tubes 3 for binding to achieve the connection of the two push tubes 3, and the cable ties are located in the vertical groove and do not protrude outside the vertical groove, so that the binding of the cable ties does not affect the fit between the push tube 3 and the slide groove 2.

[0046] The through hole 4 on the push tube 3 in this application has four functions:

[0047] (1) Effectively cooperate with the wedge-shaped positioning block 6 to achieve the fixation and pushing of the push tube 3;

[0048] (2) Standardized control of charge spacing is achieved through the hole spacing of the through holes 4;

[0049] (3) Serving as a fulcrum for the hanging of explosive tubes;

[0050] (4) Serves as the connecting fulcrum of two adjacent push tubes 3.

[0051] During use, the explosive-filled cartridge case is hung on the push tube 3 through the through hole 4. The push tube 3 is driven by the propulsion mechanism to slide along the chute 2, causing the wall of the through hole 4 to squeeze the wedge-shaped positioning block 6 back into the first groove 5, thereby pushing the cartridge case into the blasthole. When the wedge-shaped positioning block 6 is aligned with the adjacent through hole 4, the wedge-shaped positioning block 6 is inserted into the through hole 4, completing the advancement of one node. By pre-setting the spacing between adjacent cartridge cases, a fixed number of nodes are advanced, and then the next cartridge case is hung on the push tube 3 through the through hole 4, and the next cartridge case is pushed. The initial height of each cartridge case hung on the push tube 3 relative to the horizontal plane remains the same, so that the adjacent cartridge cases are spaced a predetermined distance apart. During this process, if a focused tube is used, the device can be used directly according to the installation method of this application; if a detonating cord is used, it must be passed through the cartridge case during charging to ensure blasting.

[0052] In some optional embodiments, the propulsion mechanism 8 includes a reciprocating assembly disposed on the support 1, a moving block 9 is disposed at the moving end of the reciprocating assembly, the moving block 9 is located on the side of the push tube 3 away from the chute 2, and the one-way moving distance of the moving block 9 is equal to the distance between two adjacent through holes 4;

[0053] An elastic clip 10 is provided on the moving block 9. When the elastic clip 10 is aligned with any through hole 4, the elastic clip 10 extends into the through hole 4. When the elastic clip 10 extended into the through hole 4 is aligned with the wedge-shaped positioning block 6, the first spring 7 pushes the wedge-shaped positioning block 6 into the through hole 4 and disengages the elastic clip 10 from the through hole 4.

[0054] When the drug tube is installed on the push tube 3, the wedge-shaped positioning block 6 extends into the through hole 4, and at the same time, the elastic clamp 10 extends into the adjacent through hole 4 above. When the drug tube is pushed into the blast hole, the reciprocating assembly drives the moving block 9 to move downward, thereby driving the elastic clamp 10 to apply a downward thrust to the push tube 3, so that the hole wall of the through hole 4 applies a thrust to the wedge-shaped positioning block 6. This thrust is perpendicular to the inclined surface of the wedge-shaped positioning block 6, thereby decomposing it into a downward vertical thrust and a horizontal thrust, wherein the horizontal thrust pushes the wedge-shaped positioning block 6 to squeeze inward. The first spring 7 causes the wedge-shaped positioning block 6 to retract into the first groove 5, and then the push tube 3 is pushed downward smoothly. When the wedge-shaped positioning block 6 is pushed to face the elastic clip 10, the reciprocating assembly completes a one-way motion. At this time, the first spring 7 pushes the wedge-shaped positioning block 6 into the through hole 4 and disengages the elastic clip 10 from the through hole 4. The reciprocating assembly drives the elastic clip 10 to move upward. After moving to the position of the previous through hole 4, the elastic clip 10 extends into the through hole 4, completing a reciprocating action and completing the pushing of a node.

[0055] In some optional embodiments, the elastic clamp 10 includes a fixed block 11 fixed to the moving block 9, and a second groove 12 is provided on the side wall of the fixed block 11 close to the push tube 3. A clamp 13 is slidably connected in the second groove 12, and a second spring 14 is fixed between the clamp 13 and the second groove 12. The spring coefficient of the first spring 7 is greater than the spring coefficient of the second spring 14.

[0056] In some optional embodiments, the side walls of the chute 2, the two opposite side walls of the push tube 3, and the side walls of the clamping member 13 close to the push tube 3 are all roughened.

[0057] By roughening, the friction between the side wall of the slide groove 2 and the push tube 3 is increased, and when the clamp 13 moves upward against the side wall of the push tube 3, the friction between the push tube 3 and the clamp 13 is increased, thereby increasing the upward thrust applied to the push tube 3 and reducing the risk of the push tube 3 automatically sliding down.

[0058] In some optional embodiments, the reciprocating assembly includes a connecting base 15 fixedly connected to the support 1, a slide rail fixedly connected to the connecting base 15, the slide rail is slidably connected to the moving block 9, a spindle base 16 fixedly connected to the spindle base 16, a first rotating shaft 17 is rotatably connected to the spindle base 16, a connecting rod 18 is fixedly connected to the first rotating shaft 17, an end of the connecting rod 18 away from the first rotating shaft 17 is rotatably connected to a rocker 19, and an end of the rocker 19 away from the connecting rod 18 is rotatably connected to the moving block 9.

[0059] When the first rotating shaft 17 rotates, the connecting rod 18 is driven to rotate around the first rotating shaft 17 , so that the moving block 9 is driven by the rocker 19 to reciprocate in the vertical direction.

[0060] In some optional embodiments, the first rotating shaft 17 is rotated by manual shaking. The first rotating shaft 17 rotates one circle and the moving block 9 realizes a reciprocating motion. A counting device is provided on the first rotating shaft 17 .

[0061] In this embodiment, the first rotating shaft 17 is rotated by manual shaking, and a crank 26 is fixed to the first rotating shaft 17. A counter device is provided on the first rotating shaft 17, wherein the counter device is a grating encoder, or directly adopts a skipping rope counter, etc., to realize the detection and display of the number of rotations of the crank 26.

[0062] When the medicine tube is installed on the push tube 3, the wedge-shaped positioning block 6 extends into the through hole 4, and at the same time the clamp 13 extends into the adjacent through hole 4 located above. The crank 26 is in a locked state. Without external force, the crank 26 does not rotate and the position of the push tube 3 does not move, thereby achieving stable installation of the medicine tube.

[0063] When the gun barrel is installed and pushed into the blast hole, the crank handle 26 is turned to drive the connecting rod 18 to rotate, so that the moving block 9 moves downward in the vertical direction, and the clamping member 13 applies a downward thrust to the push tube 3, so that the hole wall of the through hole 4 applies a thrust to the wedge positioning block 6, driving the wedge positioning block 6 to retract into the first groove 5, thereby realizing the smooth pushing of the push tube 3 downward.

[0064] When the crank 26 rotates a full circle, the clamp 13 moves to the position of the previous through hole 4. The clamp 13 pops out under the thrust of the second spring 14 and extends into the through hole 4. At this time, the push of one node is completed; then the crank 26 is continuously rotated to complete the push of the next node.

[0065] In some optional embodiments, the slide groove 2 is a semicircular groove, the push tube 3 is a semicircular tube, the side wall of the push tube 3 is fixed with a T-shaped anti-slip block, and a T-shaped anti-slip groove is opened on the side wall of the slide groove 2, and the T-shaped anti-slip block is in sliding contact with the T-shaped anti-slip groove.

[0066] The push tube 3 is placed in the slide groove 2. The push tube 3 can be limited in the radial direction by the arrangement of the T-shaped anti-slip block and the T-shaped anti-slip groove to prevent the push tube 3 from moving in the radial direction.

[0067] In some optional embodiments, a triangular bracket is provided at the bottom of the support 1, and the triangular bracket includes an upper connecting seat 20 and a lower fixed bracket 21. The upper connecting seat 20 and the lower fixed bracket 21 are fixedly connected by a connecting tube 22. The connecting tube 22 is a hollow tube. The connecting tube 22 passes through the upper connecting seat 20 and the lower fixed bracket 21. Three support legs 23 are provided below the lower fixed bracket 21; the support 1 is fixed to the upper connecting seat 20, and the push tube 3 is facing the inner cavity of the connecting tube 22. The inner diameter of the connecting tube 22 is larger than the outer diameter of the medicine tube.

[0068] When the tripod is supported above the blast hole, the connecting tube 22 is directly opposite to the blast hole, and the inner diameter of the connecting tube 22 allows the push tube 3 and the drug tube to pass through.

[0069] In some optional embodiments, a sliding sleeve 24 is provided on the connecting tube 22, the support leg 23 is rotatably connected to the lower fixed bracket 21, the support leg 23 is rotatably connected to a connecting frame 25 on one side close to the connecting tube 22, the other end of the connecting frame 25 is rotatably connected to the sliding sleeve 24, and a positioning piece for fixing the sliding sleeve 24 is provided on the connecting tube 22.

[0070] The positioning member includes a positioning pin. A plurality of positioning slots are provided on the connecting tube 22 along its height direction. The positioning pins pass through the sliding sleeve 24 and are inserted into the positioning slots, thereby simultaneously opening and fixing the three legs 23 .

[0071] Furthermore, a bubble fixing frame 27 is installed on the lower fixing bracket 21. The bubble fixing frame 27 contains bubbles, which can assist the operator to quickly and accurately adjust the tripod bracket to a horizontal state to ensure the horizontal calibration of the device.

[0072] Furthermore, an extension leg 28 is provided at the bottom of the leg 23 , and a receiving groove is opened at the bottom of the leg 23 . The extension leg 28 is slidably connected to the receiving groove of the leg 23 . A locking piece is provided on the leg 23 , and the locking piece is used to fix the extension leg 28 .

[0076] S3, hang the explosive tube filled with explosives on the push tube 3 through the through hole 4, and the explosive tube is located below the wedge-shaped positioning block 6;

[0077] S4. The pushing mechanism 8 drives the push tube 3 to slide along the chute 2, so that the wall of the through hole 4 squeezes the wedge-shaped positioning block 6 and retracts it into the first groove 5, thereby pushing the cartridge into the blasthole. When the wedge-shaped positioning block 6 is aligned with the adjacent through hole 4, the wedge-shaped positioning block 6 is inserted into the through hole 4, completing the advancement of one node.

During the installation process, adjust the position of the triangular bracket so that the connecting tube 22 is directly opposite the blasthole, ensuring that when the push tube 3 is subsequently pushed out, its end is exactly at the edge of the blasthole; at the same time, observe whether the bubble is in the center position to judge whether the triangular bracket is installed stably. If the bubble is off-center, readjust the triangular bracket until the bubble is adjusted to the center.

[0083] S2. Installation process of push tube 3: Place push tube 3 inside chute 2 and slide it from top to bottom. When placing it for the first time, it is necessary to manually retract the clamp 13 into the second groove 12 so that the push tube 3 can move downward smoothly and stop at the designated position.
