Description

Technical Field

[0001] The present invention relates to the technical field of gold mine blasting, and specifically to a blasting device with sectional charge loading. Background Art

[0002] In the deep-hole blasting operation of traditional gold mines, in order to achieve sectional charge loading to optimize the blasting effect and reduce the seismic effect, it is usually necessary to manually load different sections of explosives into the blast holes in batches, and set an air interval or use other packing materials between each section of explosives. This process involves multiple loadings, precise measurements, and repeated adjustments, which not only requires high experience and technical level of the operators, but also has a cumbersome and time-consuming overall operation process.

[0003] Especially in complex terrain or deep-hole conditions, it is difficult for manual operation to accurately control the spatial position and interval distance of each section of explosives, and often only rely on experience to judge, resulting in difficult-to-guarantee charge loading accuracy and affecting the stability and controllability of the blasting effect.

[0004] In addition, the traditional explosive loading method usually directly puts cartridges or explosive packages into the blast holes and only relies on the gravity of the explosives themselves or simple packing materials for fixation. However, in operating environments with deep holes, inclined holes, or relatively complex geological conditions, the explosives are prone to displacement due to their own weight, insufficient friction on the hole wall, or improper packing. Especially in the case of multi-section charge loading, the explosives between the upper and lower sections are prone to interact with each other, resulting in the displacement of the charge loading position.

[0005] More seriously, after the charge loading is completed, during the subsequent blasting preparation process, under the influence of factors such as charge loading vibration, impact, or human operation, the explosives may further sink or shift, making it difficult to ensure their designed positions in the blast holes, and ultimately affecting the reasonable distribution of explosion energy and the blasting effect.

[0006] Therefore, a blasting device with sectional charge loading is proposed. Summary of the Invention

[0007] The purpose of the present invention is to provide a blasting device with sectional charge loading to solve the problems raised in the above background art.

[0008] To achieve the above object, the present invention provides the following technical solution: A blasting device with sectional charge loading, comprising a charge loading assembly and a blast hole. The blast hole is drilled in a gold mine, and the charge loading assembly is used to load gunpowder into the blast hole. The charge loading assembly includes a base located at the top of the blast hole. A rotating shaft is fixedly connected to the top of the base, and a servo motor is fixedly connected to the end of the rotating shaft. The servo motor is divided into a fixed end and an output shaft, and the output shaft end of the servo motor faces away from the rotating shaft. A runner is rotatably connected to the rotating shaft.

An electric telescopic rod is fixedly connected to the top surface of the bottom plate, and the telescopic shaft of the electric telescopic rod faces upward. Four connecting rods are fixedly connected to the end of the telescopic shaft of the electric telescopic rod in a circular shape. A clamping plate is fixedly connected to each end of the four connecting rods away from the electric telescopic rod. A pushing ring is fixedly connected to the output shaft end of the electric telescopic rod. A guide rod is slidably connected to each of the four side plates. Both ends of the guide rod pass through the corresponding side plate. A hook plate is fixedly connected to each end of the four guide rods away from the center of the blasting charge cylinder. A second spring is sleeved on each of the four guide rods. A guide block is fixedly connected to each end of the four guide rods away from the corresponding hook plate.

[0010] Further, the servo motor is electrically connected to a remote control. The rotating shaft, the output shaft of the servo motor, the runner, and the sleeve are all concentrically arranged, and the steel cable is wound around the runner.

[0011] Further, the blasting charge cylinder is integrally in the shape of a hollow cylinder. The hollow cylinder of the blasting charge cylinder is vertically divided into two hollow semi-cylinders. One end of the two hollow semi-cylinders is hinged, and the other end is inserted and adapted.

[0012] Further, the four support plates are arranged in pairs on the hollow semi-cylinders of the two blasting charge cartridges. The two ends of the first spring are respectively fixedly connected to the sides of the support plates close to the guiding plate. The guiding plate is divided into an inclined panel and a U-shaped plate. The U-shaped plate is connected to the guiding column, and the inclined panel is located at the top of the side of the U-shaped plate away from the guiding column.

[0013] Further, the needle is arranged inside the liquid sac, and the tip of the needle faces away from the guiding column. The liquid sac is filled with foam adhesive.

[0014] Further, the end of the connecting rod away from the electric telescopic rod extends downward. The bottom of the clamping plate is set as an inclined surface, and the inclined surface of the clamping plate is in extrusion fit with the inclined panel of the guiding plate. The inclined panel of the guiding plate is on the moving path of the clamping plate.

[0015] Further, the limiting plate is set as an inverted U shape, that is, the lower half of the limiting plate is hollowed out, and the top of the side of the limiting plate away from the center of the blasting charge cartridge is set as an inclined surface. The four annular limiting plates and the four annular support plates are arranged in a staggered manner. The outer side of the top of the pushing ring is set as an inclined surface. The two ends of the second spring are respectively fixedly connected to the side plate and the side of the hook plate close to each other. The bottom end of the hook plate extends towards the center of the blasting charge cartridge.

[0016] Further, the electric telescopic rod is electrically connected to a remote controller.

[0017] Further, the bottom of the guiding block is set as an inclined surface. The guiding block is on the moving path of the pushing ring, and the inclined surface of the guiding block is in extrusion cooperation with the inclined surface of the pushing ring.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: In traditional operations, it is difficult for manual labor to accurately control the interval distance of explosives. By precisely judging the position of the steel cable through the winding and unwinding lengths of the steel cable, the real-time control of the position of the loaded explosives is achieved, avoiding the deviation of the charging position caused by human error, reducing the repeated manual operations, and simplifying the operation process of blasting charge loading.

[0019] Traditionally, gravity or simple stuffing is relied on to fix explosives, which is prone to displacement due to insufficient self-weight and friction in deep holes and inclined holes. The charging assembly tightly abuts against the hole wall of the blast hole through physical contact, and after the foam adhesive cures, chemical bonding is formed. The combination of the two can resist problems such as insufficient gravity and friction in deep holes and inclined holes of the blast hole, enabling the blasting charge cartridge to be fixed in a double-insurance manner of mechanical clamping and chemical bonding, independently limiting the position of each section of explosives in the blast hole, avoiding the position movement of the upper and lower sections of charges due to contact or external force, and ensuring that the explosives are always in the designed position throughout the whole process of blasting preparation.

[0020] Moreover, in scenarios with complex geology, deep holes, or inclined holes, the traditional stuffing method is prone to failure due to irregular hole walls. However, the physical clamping and wall support of the charging assembly can adapt to the shape of the blast hole wall, and the foam adhesive fills the tiny gaps, achieving stable fixation under all working conditions and expanding the application range of the staged charging technology.

[0021] Meanwhile, the steel cable and the blasting charging cylinder are connected in a press - detachable manner, allowing for quick assembly and separation without tools, saving the preparation time for staged charging and shortening the overall operation cycle. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Among them: Referring to Figure 1 、 Figure 2 As shown, the blast hole 11 is vertically drilled in the gold mine, that is, the blast hole 11 is used for vertical charge filling to blast the gold mine.

[0027] It should be added that the segmented charge loading inside the blast hole 11 adopts an air interval here.

[0028] The charging assembly includes a base 21, which is located at the top of the blast hole 11. A rotating shaft 22 is fixedly connected to the top of the base 21. The end of the rotating shaft 22 is fixedly connected to a servo motor 23. The servo motor 23 is divided into a fixed end and an output shaft. The output shaft end of the servo motor 23 faces away from the rotating shaft 22. A runner 24 is rotatably connected to the rotating shaft 22. The output shaft end of the servo motor 23 is fixedly connected to a sleeve 25. One side of the sleeve 25 close to the runner 24 is fixedly connected to the runner 24. A steel cable 26 is fixedly connected to the runner 24. One end of the steel cable 26 away from the runner 24 is provided with a blasting charge cartridge 27. Four support plates 28 are fixedly connected to the top surface of the blasting charge cartridge 27 in an annular array. A guiding column 29 is slidably connected to each of the four support plates 28. One end of each of the four guiding columns 29 close to the center of the blasting charge cartridge 27 is fixedly connected to a guiding plate 210. A first spring 211 is sleeved on each of the four guiding columns 29. The two ends of the first spring 211 are respectively connected to the support plate 28 and the guiding plate 210. One end of each of the four guiding columns 29 away from the corresponding guiding plate 210 is fixedly connected to a pressing plate 212. A liquid sac 213 is fixedly connected to one side of each of the four pressing plates 212 away from the corresponding guiding column 29. A plurality of needle pins 214 are fixedly connected to one side of each of the four pressing plates 212 close to the corresponding liquid sac 213. A protective cylinder 215 is threadedly connected to each of the four pressing plates 212. Four limiting plates 216 are fixedly connected to the top surface of the blasting charge cartridge 27 in an annular array. One end of the steel cable 26 away from the runner 24 is connected to a top plate 217. Four side plates 218 are fixedly connected to the bottom surface of the top plate 217 in an annular array. A bottom plate 219 is fixedly connected to the bottom ends of the four side plates 218. An electric telescopic rod 220 is fixedly connected to the top surface of the bottom plate 219. The telescopic shaft of the electric telescopic rod 220 faces upward. Four connecting rods 221 are fixedly connected to the telescopic shaft end of the electric telescopic rod 220 in an annular shape. One end of each of the four connecting rods 221 away from the electric telescopic rod 220 is fixedly connected to a clamping plate 222. A pushing ring 223 is fixedly connected to the end of the telescopic shaft of the electric telescopic rod 220. A guiding rod 224 is slidably connected to each of the four side plates 218. Both ends of the guiding rod 224 penetrate through the corresponding side plate 218. One end of each of the four guiding rods 224 away from the center of the blasting charge cartridge 27 is fixedly connected to a hook plate 225. A second spring 226 is sleeved on each of the four guiding rods 224. A guiding block 227 is fixedly connected to one end of each of the four guiding rods 224 away from the corresponding hook plate 225.

[0029] Among them: As shown in Figure 3 the figure, the servo motor 23 is electrically connected to a remote controller. The rotating shaft 22, the output shaft of the servo motor 23, the runner 24, and the sleeve 25 are all arranged concentrically. That is, when the servo motor 23 is started under the control of the remote controller, the rotation of the output shaft of the servo motor 23 can drive the runner 24 to rotate on the rotating shaft 22 through the sleeve 25.

[0030] It should be added that: As shown inFigure 3 As shown, the steel cable 26 is wound around the rotating wheel 24. Combining with the above text, that is, the rotation of the output shaft of the servo motor 23 can control the winding and unwinding of the steel cable 26.

[0031] Among them: Refer to Figure 1 、 Figure 2 、 Figure 7 As shown, the blasting charge cartridge 27 is set as a disposable tool. The blasting charge cartridge 27 is designed and produced according to the size of the blast hole 11 and the actual charge amount. The overall shape of the blasting charge cartridge 27 is a hollow cylinder. The hollow cylinder of the blasting charge cartridge 27 is vertically divided into two hollow semi-cylinders. One end of the two hollow semi-cylinders is hinged, and the other end is inserted and adapted. The user can add explosives to its interior by opening the two hollow semi-cylinders. After adding, the user can rotate and close the two hollow semi-cylinders, and use adhesive tape to bond and fix the outer walls of the two hollow semi-cylinders together, so that the gunpowder cannot spill out inside the blasting charge cartridge 27.

[0032] Among them: Refer to Figures 4 to 10 As shown, four support plates 28 are arranged in pairs on the hollow semi-cylinders of the two blasting charge cartridges 27. The two ends of the first spring 211 are respectively fixedly connected to the closer sides of the support plate 28 and the guide plate 210. The guide plate 210 is divided into an inclined panel and a U-shaped plate. The U-shaped plate is connected to the guide post 29. The inclined panel is located at the top of the side of the U-shaped plate away from the guide post 29.

[0033] Among them: Refer to Figure 4 、 Figure 9 、 Figure 10 As shown, the needle 214 is arranged inside the liquid capsule 213. The tip of the needle 214 faces away from the guide post 29. The liquid capsule 213 is filled with foam adhesive. The foam adhesive is a known prior art. The foam adhesive has the following characteristics: It has both foaming and expanding functions and bonding properties. The initial state of the foam adhesive is liquid. It expands and cures rapidly after contacting air, fills irregular gaps, and at the same time adheres to the surface of the object through viscous substances, and finally forms a foam layer with buffering, sealing and fixing functions. The function of the needle 214 is: The needle 214 is used to firmly grasp the groove wall of the blast hole 11 through the tip, and is used to pierce the liquid capsule 213, so that the foam adhesive inside the liquid capsule 213 flows out to take effect.

[0034] Among them: Refer to Figure 9 As shown, the function of the protection cylinder 215 is: to ensure that when it is not necessary to charge the inside of the blast hole 11, the liquid capsule 213 will not be affected by the outside world, resulting in abnormal leakage of the foam adhesive inside it. It should be added that: when it is necessary to charge the inside of the blast hole 11, the user needs to screw out the protection cylinder 215 from the bottom plate 212, so that the liquid capsule 213 is exposed, and then put the blasting charge barrel 27 into the blast hole 11 for installation.

[0035] Wherein: referring to Figure 4 and Figures 8 to 10 As shown, one end of the connecting rod 221 away from the electric telescopic rod 220 extends downward, the bottom of the clamping plate 222 is set as an inclined surface, and the inclined surface of the clamping plate 222 is extrusion-fitted with the inclined panel of the guide plate 210. The inclined panel of the guide plate 210 is located on the moving path of the clamping plate 222. Specifically: when the clamping plate 222 moves downward, under the combined action of the inclined surface of the clamping plate 222 and the inclined panel of the guide plate 210, the clamping plate 222 can be inserted into the U-shaped plate of the guide plate 210, and at the same time, the guide plate 210 is displaced in a direction away from the guide post 29, so that the guide post 29 moves on the support plate 28 in a direction away from the center of the blasting charge cartridge 27, and at the same time, the first elastic stretching spring 211 is elastically stretched. Similarly, when the clamping plate 222 moves upward, the clamping plate 222 no longer restricts the elastic reset of the first spring 211. Therefore, under the elastic contraction action of the first spring 211, the first spring 211 pulls the guide post 29 to move in a direction away from the center of the blasting charge cartridge 27, that is, the guide post 29 drives the abutting plate 212 to move synchronously in a direction away from the center of the blasting charge cartridge 27. If the blasting charge cartridge 27 is located inside the blast hole 11 at this time, that is, the abutting plate 212, the liquid sac 213, and the needle 214 move toward the groove wall of the blast hole 11. Specifically: combining the supplement of the liquid sac 213 and the needle 214 in the above text, it can be obtained that when the blasting charge cartridge 27 is located inside the blast hole 11, the clamping plate 222 moves upward, causing the abutting plate 212 to move toward the groove wall of the blast hole 11. Then the liquid sac 213 squeezes the groove wall of the blast hole 11 and deforms. As the abutting plate 212 continues to move, the abutting plate 212 abuts against the groove wall of the blast hole 11 through the needle 214. At this time, the needle 214 and the groove wall of the blast hole 11 are in extrusion contact through the liquid sac 213, so that the blasting charge cartridge 27 is restricted from falling inside the blast hole 11, that is, the position of the blasting charge cartridge 27 inside the blast hole 11 is fixed. And the needle 214 and the groove wall of the blast hole 11 are in contact through the liquid sac 213. Under the action of the tip of the needle 214, the liquid sac 213 is punctured, and the foam adhesive inside the liquid sac 213 flows out to the outside and contacts the air. The foam adhesive quickly expands and solidifies and bonds the blasting charge cartridge 27 and the blast hole 11, so that the position of the blasting charge cartridge 27 inside the blast hole 11 is mechanically clamped by the needle 214 and chemically bonded by the foam adhesive at the same time, thus ensuring that the position of the blasting charge cartridge 27 inside the blast hole 11 is the charging position required by the user.

[0036] Wherein: referring to Figure 4 、 Figure 6 and Figure 7 As shown, the limiting plate 216 is set as an inverted U shape, that is, the lower half of the limiting plate 216 is hollowed out, and the top of the side of the limiting plate 216 away from the center of the blasting charge cartridge 27 is set as an inclined surface. It should be noted that: the four annularly arranged limiting plates 216 and the four annularly arranged 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.

[0037] Among them: Refer to Figure 4 、 Figure 6 As shown, the outer side of the top of the push ring 223 is set as an inclined surface.

[0038] Among them: Refer to Figure 4 、 Figure 6 As shown, both ends of the second spring 226 are fixedly connected to the side plates 218 and the side close to the hook plate 225 respectively.

[0039] Among them: Refer to Figure 4 、 Figure 6 And Figure 8 As shown, the bottom end of the hook plate 225 extends towards the center of the blasting charge cartridge 27. The bottom end of the hook plate 225 is set as an inclined surface, and the inclined surface of the hook plate 225 is in extrusion fit 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 inclined surface at the bottom end of the hook plate 225 abuts against the top inclined surface of the limiting plate 216. Then, under the guiding action of the inclined surface, the hook plate 225 moves towards the side away from the center of the blasting charge cartridge 27. At the same time, the hook plate 225 drives the guide rod 224 to move synchronously and elastically stretches the second spring 226. When the hook plate 225 moves downward to the hollow position of the limiting plate 216, at this time, the hook plate 225 no longer abuts against the inclined surface of the limiting plate 216. Then, under the elastic contraction action of the second spring 226, the hook plate 225 and the guide rod 224 move towards the center of the blasting charge cartridge 27. As the hook plate 225 moves, the bottom end of the hook plate 225 is inserted into the hollow position of the limiting plate 216, forming a state where the hook plate 225 hooks the limiting plate 216. That is, the steel cable 26 vertically limits the blasting charge cartridge 27 through the cooperation of four hook plates 225 and the corresponding limiting plates 216, so that when the steel cable 26 is wound and unwound, the steel cable 26 can drive the blasting charge cartridge 27 to move up and down. It should be noted that: The user can calculate the length of the steel cable 26 wound and unwound, such as setting scales on the steel cable 26, to calculate the position where the blasting charge cartridge 27 moves downward inside the blast hole 11.

[0040] Among them: The electric telescopic rod 220 is electrically connected to a remote controller.

[0041] Among them: Refer to Figure 4 、 Figure 6As shown, the bottom of the guiding block 227 is set as an inclined plane. The guiding block 227 is located on the moving path of the pushing ring 223. The inclined plane of the guiding block 227 is in extrusion fit with the inclined plane of the pushing ring 223. Specifically: when the pushing ring 223 moves upward, the pushing ring 223 abuts against the guiding block 227. Through the guidance of the inclined plane, the guiding block 227 pushes the guiding rod 224 in the direction away from the center of the blasting charge cartridge 27, and then the guiding rod 224 slides on the side plate 218 in the direction of the hook plate 225. The guiding rod 224 drives the hook plate 225 to move to a position where it does not abut against the limiting plate 216, and elastically stretches the second spring 226. At this time, as the hook plate 225 moves, the hook plate 225 is decoupled from the limiting plate 216, that is, the steel cable 26 no longer limits the blasting charge cartridge 27, thereby forming a detachable connection between the steel cable 26 and the blasting charge cartridge 27.

[0042] It should be added that: in summary, and with reference to Figure 4 、 Figure 6 As shown, as the telescopic shaft end of the electric telescopic rod 220 moves upward, it can realize that the position of the blasting charge cartridge 27 inside the blast hole 11 is mechanically clamped by the clamping pin 214 and chemically bonded by the foam adhesive at the same time, and it can also realize the decoupling of the hook plate 225 from the limiting plate 216, that is, the steel cable 26 no longer limits the blasting charge cartridge 27, and it can simultaneously realize the decoupling of the blasting charge cartridge 27 and the fixation of its position inside the blast hole 11.

[0043] 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 first disengages from the inside of the guiding plate 210, and the double-insurance fixing method of the blasting charge cartridge 27 takes effect first. Subsequently, the steel cable 26 is decoupled from the blasting charge cartridge 27, so that when the position of the blasting charge cartridge 27 is restricted by the steel cable 26, a certain effective time is left for the double-insurance fixing method of the blasting charge cartridge 27 to ensure that the position of the blasting charge cartridge 27 inside the blast hole 11 remains unchanged before the clamping pin 214 abuts against the groove wall of the blast hole 11, that is, to ensure that the charging position of the blasting charge cartridge 27 inside the blast hole 11 is the accurate position required by the user.

[0044] In the initial stage of the charging assembly, that is, the preparatory stage before charging the inside of the blast hole 11, since the blasting charge cartridge 27 is a disposable item, all the structures installed on the blasting charge cartridge 27 are disposable items, and the charging of the inside of the blast hole 11 is segmented, that is, it is necessary to load the blasting charge cartridge 27 multiple times inside the blast hole 11. After the structure on the steel cable 26 is loaded once, it needs to be connected to the structure on the blasting charge cartridge 27 to be loaded. At this time, the user ensures that the telescopic end of the electric telescopic rod 220 retracts, and then the user presses the bottom plate 219 against the center position of the top of the blasting charge cartridge 27. As a result, the clamping plate 222 and the hook plate 225 are pressed down synchronously. The clamping plate 222 abuts against the guide plate 210, causing the first spring 211 to be elastically stretched. The abutting plate 212 and the liquid sac 213 are moved to the side close to the center of the blasting charge cartridge 27. The hook plate 225 is pressed down and hooked to the limit plate 216, thereby realizing the quick installation of the blasting charge cartridge 27 on the steel cable 26. And this step only requires the user to press, saving the preparation time during segmented charging.

[0045] When the charging assembly is operating, that is, when it is necessary to load multiple blasting charge cartridges 27 into the blast hole 11 in a segmented manner with an air interval, at this time, the user puts the blasting charge cartridge 27 into the blast hole 11 and controls the unwinding of the steel cable 26 through the remote control, so that the blasting charge cartridge 27 descends inside the blast hole 11. When the user calculates that the blasting charge cartridge 27 is at the position where charging is required inside the blast hole 11 according to the unwinding length of the steel cable 26, at this time, the user controls the telescopic shaft of the electric telescopic rod 220 to extend through the remote control, so that the blasting charge cartridge 27 is mechanically clamped and chemically bonded inside the blast hole 11. At the same time, the steel cable 26 is decoupled from the blasting charge cartridge 27. The user repeats the initial stage of the charging assembly for preparation, and so on, until multiple blasting charge cartridges 27 are arranged at the segmented charging positions required by the user inside the blast hole 11. At this time, the user removes the structure on the base 21 while keeping the steel cable 26 decoupled from the blasting charge cartridge 27, leaving only multiple blasting charge cartridges 27 in the blast holes 11 at the blasting site.

[0046] In summary, the charging assembly can achieve the following beneficial effects: In traditional operations, it is difficult for manual labor to accurately control the distance between explosives. By precisely judging the position of the steel cable 26 through the unwinding and rewinding lengths of the steel cable 26, the real-time control of the position of the loaded explosives is realized, avoiding the deviation of the charging position caused by human error, reducing repeated manual operations, and simplifying the operation process of blasting charging Traditionally, explosives are fixed by relying on gravity or simple stuffing, which is prone to displacement in deep holes and inclined holes due to insufficient self-weight, friction, etc. The charging assembly tightly abuts against the wall of the blast hole 11 through physical contact, and after the foam adhesive cures, chemical bonding is formed. The combination of the two can resist problems such as insufficient gravity and friction in deep holes and inclined holes of the blast hole 11, enabling the blasting charge cartridge 27 to be fixed in a double-insurance manner of mechanical clamping and chemical bonding, independently limiting the position of each section of explosive in the blast hole 11, preventing the upper and lower sections of the charge from moving due to contact or external force, and ensuring that the explosive is always in the designed position throughout the entire process of blasting preparation.

[0047] Moreover, in scenarios with complex geology, deep holes, or inclined holes, the traditional stuffing method is prone to failure due to irregular hole walls. The physical clamping and bracing of the charging assembly can adapt to the shape of the wall of the blast hole 11, and the foam adhesive fills the tiny gaps, achieving stable fixation under all working conditions and expanding the application scope of the sectional charging technology.

[0048] Meanwhile, the steel cable 26 and the blasting charge cartridge 27 are connected in a press-type detachable manner, and the assembly and separation can be quickly completed without tools, saving the preparation time for sectional charging and shortening the overall operation cycle.
