Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gold mine blasting, in particular to a blasting device capable of segmented charging. BACKGROUND

[0002] In the deep hole blasting operation of traditional gold mines, in order to achieve segmented charging to optimize the blasting effect and reduce the seismic effect, it is usually necessary to manually charge different segment explosives into the blast hole in batches, and to set air interval or use other filling materials between each segment of explosives. This process involves multiple filling, accurate measurement and repeated adjustment, which not only requires higher experience and technical level of the operator, but also has a complicated overall operation process and time-consuming.

[0003] Especially in complex terrain or deep hole conditions, manual operation is difficult to accurately control the spatial position and interval distance of each segment of explosives, often can only rely on experience to judge, resulting in difficulty in ensuring the charging accuracy, affecting the stability and controllability of the blasting effect.

[0004] In addition, the traditional explosive filling method usually puts the cartridge or charge directly into the blast hole, and only relies on the gravity of the explosive or simple filling to fix. However, in deep hole, inclined hole or complex geological conditions, the explosive is easy to displace due to the action of its own weight, insufficient friction of the hole wall or incomplete filling. Especially in the case of multi-segment charging, the explosives between the upper and lower segments are easy to affect each other, resulting in displacement of the charging position.

[0005] More seriously, after the charging is completed, under the influence of factors such as explosive vibration, impact or human operation in the subsequent blasting preparation process, the explosive may further sink or displace, so that its designed position in the blast hole is difficult to ensure, and finally the reasonable distribution of explosion energy and the blasting effect are affected.

[0042] It should be noted that:Figure 3 As shown, the steel cable 26 is arranged in a winding manner on the runner 24, in combination with the above, i.e. the rotation of the output shaft of the servo motor 23 can control the winding and unwinding of the steel cable 26.

[0043] Wherein, referring to Figure 1 , Figure 2 , Figure 7 As shown, the blasting cartridge 27 is designed as a disposable tool, the blasting cartridge 27 is designed and produced according to the size of the blast hole 11 and the actual charge amount, the blasting cartridge 27 as a whole presents a hollow cylindrical shape, the hollow cylinder of the blasting cartridge 27 is split into two hollow half-cylinders along the vertical direction, one end of the two hollow half-cylinders is hinged, and the other end is inserted and adapted, the user can add explosives to the inside of the two hollow half-cylinders by opening them, after the addition is completed, the user can rotate and close the two hollow half-cylinders, and use adhesive tape to stick and fix the outer walls of the two hollow half-cylinders together, so that the gunpowder cannot spill out of the blasting cartridge 27.

[0044] Wherein, referring to Figures 4 to 10 As shown, the four support plates 28 are arranged on the hollow half-cylinders of the two blasting cartridges 27, respectively, the two ends of the spring 211 are fixedly connected to the side of the support plate 28 close to the guide plate 210, the guide plate 210 is divided into an inclined plate and a U-shaped plate, the U-shaped plate is connected with the guide column 29, and the inclined plate is located at the top of the side away from the guide column 29 of the U-shaped plate.

[0045] Wherein, referring to Figure 4 , Figure 9 , Figure 10 As shown, the clamping needle 214 is arranged in the liquid tank 213, the tip of the clamping needle 214 faces away from the guide column 29, the liquid tank 213 contains a foamed adhesive, the foamed adhesive is a known technology, the foamed adhesive has the following characteristics: it has the functions of foaming and expanding and adhesion, the initial state of the foamed adhesive is liquid, it expands and solidifies rapidly after contacting with air, it fills irregular gaps, and at the same time, it adheres to the surface of an object through viscosity, and finally forms a foamed layer with the functions of buffering, sealing and fixing. The function of the clamping needle 214 is to grasp the groove wall of the blast hole 11 through the tip, and to pierce the liquid tank 213, so that the foamed adhesive in the liquid tank 213 flows out to take effect.

[0046] Wherein, referring to Figure 9 As shown, the protection cylinder 215 has the function of ensuring that the liquid tank 213 will not be affected by the outside world and cause the foamed adhesive in it to leak abnormally when it is not necessary to charge the blast hole 11. It should be noted that when it is necessary to charge the blast hole 11, the user needs to screw the protection cylinder 215 out of the abutment plate 212, so that the liquid tank 213 is exposed, and then the blasting cartridge 27 is placed in the blast hole 11 for installation.

[0047] wherein: refer to Figure 4 with Figures 8 to 10 As shown in the figure, the connecting rod 221 extends downward from the end away from the electric telescopic rod 220, the bottom of the clamping plate 222 is provided as an inclined surface, and the inclined surface of the clamping plate 222 is pressed and matched with the inclined surface plate of the guide plate 210, the inclined surface plate of the guide plate 210 is located on the moving path of the clamping plate 222, specifically: when the clamping plate 222 moves downward, the clamping plate 222 is inserted into the U-shaped plate of the guide plate 210 under the cooperation of the inclined surface of the clamping plate 222 and the inclined surface plate of the guide plate 210, at the same time, the guide plate 210 is displaced away from the guide column 29, and the guide column 29 is moved on the support plate 28 away from the center of the blasting cartridge 27, and the elastic spring one 211 is stretched. Similarly, when the clamping plate 222 moves upward, the clamping plate 222 no longer limits the elastic return of the spring one 211, and then under the elastic contraction of the spring one 211, the spring one 211 pulls the guide column 29 to move away from the center of the blasting cartridge 27, that is, the guide column 29 drives the abutting plate 212 to move away from the center of the blasting cartridge 27, and if the blasting cartridge 27 is located inside the blasthole 11 at this time, the abutting plate 212, the liquid bag 213 and the clamping needle 214 move towards the slot wall of the blasthole 11. Specifically: in combination with the supplement of the liquid bag 213 and the clamping needle 214 in the foregoing, it can be concluded that when the blasting cartridge 27 is located inside the blasthole 11, the clamping plate 222 moves upward, so that the abutting plate 212 moves towards the slot wall of the blasthole 11, and then the liquid bag 213 extrudes the slot wall of the blasthole 11 and deforms, with the continuous displacement of the abutting plate 212, the abutting plate 212 abuts against the slot wall of the blasthole 11 through the clamping needle 214, at this time, the clamping needle 214 and the slot wall of the blasthole 11 are abutted through the extrusion of the liquid bag 213, so that the blasting cartridge 27 is limited from falling inside the blasthole 11, that is, the position of the blasting cartridge 27 inside the blasthole 11 is fixed, and the clamping needle 214 and the slot wall of the blasthole 11 are abutted through the liquid bag 213, under the action of the tip of the clamping needle 214, the liquid bag 213 is pierced, the foam adhesive inside the liquid bag 213 flows out to contact the air outside, the foam adhesive rapidly expands, solidifies and bonds the blasting cartridge 27 and the blasthole 11, so that the position of the blasting cartridge 27 inside the blasthole 11 is mechanically clamped by the clamping needle 214 and chemically bonded by the foam adhesive at the same time, thereby ensuring that the position of the blasting cartridge 27 inside the blasthole 11 is the desired charging position of the user.

[0048] wherein: refer to Figure 4 , Figure 6 and Figure 7 As shown in the figure, the limiting plate 216 is provided as an inverted U-shaped, that is, the lower half of the limiting plate 216 is hollow, and the top of the side of the limiting plate 216 away from the center of the blasting cartridge 27 is provided as an inclined surface, it should be noted that the four ring-shaped limiting plates 216 and the four ring-shaped support plates 28 are arranged in a staggered manner, so that the limiting plate 216 and the support plate 28 do not interfere with each other.

[0049] As shown in Figure 4 , Figure 6 , the top outer side of the push ring 223 is provided with an inclined surface.

[0050] As shown in Figure 4 , Figure 6 , the two ends of the spring two 226 are respectively fixedly connected with the side plate 218 and the hook plate 225 close to one side.

[0051] As shown in Figure 4 , Figure 6 and Figure 8 , the bottom end of the hook plate 225 extends to the center direction of the blasting charge cylinder 27, the bottom end of the hook plate 225 is provided with an inclined surface, and the inclined surface of the hook plate 225 is extruded and matched with the inclined surface of the limiting plate 216, the limiting plate 216 is located on the moving path of the hook plate 225, when the hook plate 225 moves downward, the bottom end inclined surface of the hook plate 225 is in contact with the top inclined surface of the limiting plate 216, and then the hook plate 225 moves away from the center of the blasting charge cylinder 27 under the guidance of the inclined surface, at the same time, the hook plate 225 drives the guide rod 224 to move synchronously and stretch the spring two 226 elastically, when the hook plate 225 moves to the hollow position of the limiting plate 216, the hook plate 225 no longer contacts with the inclined surface of the limiting plate 216, and then the hook plate 225 and the guide rod 224 move to the center direction of the blasting charge cylinder 27 under the elastic contraction of the spring two 226, with the movement of the hook plate 225, the bottom end of the hook plate 225 is inserted into the hollow position of the limiting plate 216, forming the state that the hook plate 225 hooks the limiting plate 216, that is, the steel cable 26 is limited in the vertical direction by the cooperation of the four hook plates 225 and the corresponding limiting plates 216, so that the steel cable 26 can drive the blasting charge cylinder 27 to move up and down when the steel cable 26 is wound and unwound. It should be noted that the user can calculate the length of the steel cable 26 wound and unwound, such as setting a scale on the steel cable 26, to calculate the position of the blasting charge cylinder 27 inside the blast hole 11.

[0052] As shown in ,

[0053] , the electric telescopic rod 220 is electrically connected with a remote controller. Figure 4 Figure 6As shown, the bottom of the guide block 227 is provided with a slope, and the guide block 227 is located on the moving path of the push ring 223. The slope of the guide block 227 is in extrusion fit with the slope of the push ring 223. Specifically, when the push ring 223 moves upward, the push ring 223 abuts against the guide block 227, and is guided by the slope, so that the guide block 227 pushes the guide rod 224 away from the center of the blasting cartridge 27, and then the guide rod 224 slides on the side plate 218 to the direction of the hook plate 225, and the guide rod 224 drives the hook plate 225 to move away from the limiting plate 216 and elastically stretch the second spring 226. At this time, with the movement of the hook plate 225, the hook plate 225 is unhooked from the limiting plate 216, that is, the steel cable 26 no longer limits the blasting cartridge 27, so as to form the detachable connection between the steel cable 26 and the blasting cartridge 27.

[0054] It should be noted that: on the basis of the above, referring to Figure 4 、 Figure 6 As shown, with the upward movement of the telescopic shaft end of the electric telescopic rod 220, the position of the blasting cartridge 27 in the blast hole 11 can be simultaneously mechanically clamped by the clamping needle 214 and chemically bonded by the foam adhesive, and the hook plate 225 can be unhooked from the limiting plate 216, that is, the steel cable 26 no longer limits the blasting cartridge 27, and the unhooking of the blasting cartridge 27 and the fixing of the position of the blasting cartridge 27 in the blast hole 11 can be simultaneously realized.

[0055] It should be noted that: the upward movement of the telescopic shaft end of the electric telescopic rod 220 is a continuous process. Specifically, the clamping plate 222 is first separated from the inside of the guide plate 210, and then the steel cable 26 is unhooked from the blasting cartridge 27, so that the blasting cartridge 27 has a certain effective time for the double insurance fixing mode under the limitation of the steel cable 26, which ensures that the position of the blasting cartridge 27 in the blast hole 11 remains unchanged before the clamping needle 214 abuts against the slot wall of the blast hole 11, that is, the charging position of the blasting cartridge 27 in the blast hole 11 is the required accurate position for the user.

[0056] In the initial stage of the charging assembly, that is, the preparation stage before the inside of the blast hole 11 needs to be charged, since the blasting cartridge 27 is a disposable product, the structures installed on the blasting cartridge 27 are also disposable products, and the charging of the inside of the blast hole 11 is segmented, that is, multiple charging of the blasting cartridge 27 needs to be carried out in the inside of the blast hole 11, and the structure on the steel cable 26 needs to be connected with the structure on the blasting cartridge 27 to be filled after one filling is completed. At this time, the user ensures that the telescopic end of the electric telescopic rod 220 is retracted, and then the user presses the bottom plate 219 against the top center position of the blasting cartridge 27, and then the clamping plate 222 and the hook plate 225 are synchronously pressed down, the clamping plate 222 is in contact with the guide plate 210, the spring 211 is elastically stretched, the stop plate 212 and the liquid chamber 213 are moved to one side close to the center of the blasting cartridge 27, and the hook plate 225 is pressed down and hooked with the limiting plate 216, so as to realize the quick installation of the blasting cartridge 27 on the steel cable 26, and the step only needs to be pressed by the user, thereby saving the preparation time during segmented charging.

[0057] When the charging assembly is running, that is, multiple blasting cartridges 27 are segmented and charged into the inside of the blast hole 11 in an air-spaced manner, at this time the user puts the blasting cartridge 27 into the inside of the blast hole 11, and controls the steel cable 26 to be unwound through the remote controller, so that the blasting cartridge 27 is lowered in the inside of the blast hole 11. When the user calculates the position of the blasting cartridge 27 in the inside of the blast hole 11 according to the unwound length of the steel cable 26, the user controls the telescopic shaft of the electric telescopic rod 220 to be stretched through the remote controller, so that the blasting cartridge 27 is mechanically clamped and chemically bonded in the inside of the blast hole 11, and at the same time the steel cable 26 is unhooked from the blasting cartridge 27. The user repeats the preparation of the initial stage of the charging assembly, and reciprocates until multiple blasting cartridges 27 are arranged in the inside of the blast hole 11 according to the segmented charging positions required by the user. At this time, the user removes the structures on the base 21 while keeping the steel cable 26 unhooked from the blasting cartridge 27, and only leaves multiple blasting cartridges 27 in the blast hole 11 in the blasting site.

[0058] In summary, the charging assembly can achieve the following beneficial effects:

[0059] In the traditional operation, it is difficult for manual operation to accurately control the interval distance of explosives. The position of the steel cable 26 is accurately judged by the unwound and wound length of the steel cable 26, the position of the filled explosive is realized in real time, the charging position deviation caused by human error is avoided, the manual repeated operation is reduced, and the operation process of the blasting charge is simplified

[0060] The traditional fixed explosive relies on gravity or simple packing. In deep holes and inclined holes, the explosive is easy to shift due to insufficient gravity and friction. The charging assembly is tightly pressed against the hole wall of the blast hole 11 through physical contact, and chemical bonding is formed after the curing of the foam adhesive. The combination of the two can resist the problems of insufficient gravity and friction in deep holes and inclined holes of the blast hole 11, so that the blasting charge cylinder 27 can be fixed by the double insurance of mechanical clamping and chemical bonding, and the position of each section of explosive in the blast hole 11 is independently limited, avoiding the position shift of the upper and lower sections of explosive due to contact or external force, and ensuring that the explosive is always in the designed position during the whole blasting preparation process.

[0061] In addition, in the scene of complex geology or deep holes and inclined holes, the traditional packing method is easy to fail due to irregular hole wall, while the physical clamping and wall supporting of the charging assembly can adapt to the shape of the blast hole 11, and the foam adhesive fills the small gaps to realize stable fixation in all working conditions, thereby expanding the application range of the segmented charging technology.

[0062] At the same time, the steel cable 26 and the blasting charge cylinder 27 are connected in a pressing manner, which can be quickly assembled and separated without tools, saving the preparation time of the segmented charging and shortening the overall operation cycle.
