Description

Technical Field

[0001] This utility model relates to the field of open-pit blasting technology, specifically a centrally segmented emulsion explosive enhancement charging device. Background Technology

[0002] In the field of blasting engineering, for blasting operations on hard rock, appropriate charging devices are required to achieve efficient and stable blasting results. The design and performance of the charging device directly affect the transmission of the detonation wave, the fixation of the device in the borehole wall, and the overall efficiency and quality of the blasting operation.

[0003] Existing charging devices have certain shortcomings. On the one hand, regarding detonation wave transmission, some devices struggle to effectively transmit and diffuse the detonation wave, resulting in insufficient release of blasting energy and affecting the blasting effect. On the other hand, in terms of device fixation, some devices lack sufficient stability within the borehole wall, making them prone to displacement during blasting and affecting the accuracy and safety of the blasting. Furthermore, existing devices struggle to reasonably adjust the length of each charging tube when dealing with varying thicknesses of hard rock, and the installation process is not convenient, with poor structural stability. These combined problems limit the efficiency and quality of blasting operations. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrally segmented emulsion explosive enhancement charging device, comprising: A central emulsion detonation enhancer tube, wherein a detonating cord detonation transmission tube is inserted into the inner cavity of the central emulsion detonation enhancer tube, and detonation wave transmission holes are evenly distributed on the surface of the detonating cord detonation transmission tube. An open-type hole wall fixing mechanism is installed on the surface of the central emulsification explosion-enhancing tube, and a suspension mechanism is installed on the surface of the open-type hole wall fixing mechanism; A first connecting cylinder is disposed on the surface of the central emulsification explosion-enhancing tube. A second connecting cylinder is disposed on the surface of the first connecting cylinder. The first connecting cylinder and the second connecting cylinder are combined to form the central emulsification explosion-enhancing tube. A connecting tube is installed at the connecting end of the second connecting cylinder. The first connecting cylinder is screwed onto the surface of the connecting tube. A rotating block is disposed on the surface of the connecting pipe. A mounting plate is installed on the surface of the rotating block, and a first spring is installed on the surface of the mounting plate. A limit clamp is installed at the output end of the first spring.

[0006] Preferably, limit rods are installed on both sides of the surface of the limiting hoop, and the limit rods penetrate the surface of the mounting plate. The limit rods can limit the limiting hoop so that the limiting hoop will not shift.

[0007] Preferably, the connecting ends of the central emulsion detonation tube are all equipped with sealing rings. The inner ring of the sealing ring is in close contact with the surface of the detonating cord transmission tube. The sealing ring can effectively prevent external substances from entering the interior of the central emulsion detonation tube, avoid damage to the detonating cord transmission tube, and ensure the detonation transmission effect of the entire device.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model provides a technical solution: a centrally segmented emulsion explosive-enhancing charging device. Please refer to [link / reference]. Figure 1 It includes a central emulsion detonation tube 1, and a detonating cord transmission tube 2 is inserted into the inner cavity of the central emulsion detonation tube 1. Please refer to [link / reference]. Figure 2 The surface of the detonating cord transmission tube 2 is uniformly provided with detonation wave transmission holes 3; A support-type hole wall fixing mechanism 4 is set on the surface of the central emulsification explosion-enhancing tube 1, and a suspension mechanism 5 is installed on the surface of the support-type hole wall fixing mechanism 4; Please see Figure 3 The first connecting cylinder 6 is disposed on the surface of the central emulsification and explosion-enhancing tube 1. The surface of the first connecting cylinder 6 is provided with a second connecting cylinder 7. The first connecting cylinder 6 and the second connecting cylinder 7 are combined to form the central emulsification and explosion-enhancing tube 1. The connecting end of the second connecting cylinder 7 is equipped with a connecting pipe 8. The first connecting cylinder 6 is screwed onto the surface of the connecting pipe 8. A rotating block 9 is disposed on the surface of the connecting pipe 8. A mounting plate 10 is mounted on the surface of the rotating block 9. A first spring 11 is mounted on the surface of the mounting plate 10. A limit clamp 12 is mounted on the output end of the first spring 11.

[0016] The detonation wave transmission holes 3, evenly distributed on the surface of the detonating cord transmission tube 2 inside the central emulsion detonation tube 1, can effectively transmit and diffuse the detonation wave. Combined with the suspension mechanism 5 on the surface of the open-type hole wall fixing mechanism 4, the device's stability in the hole wall can be enhanced. The combination structure of the first connecting tube 6 and the second connecting tube 7, screwed together by the connecting tube 8, allows for reasonable adjustment of the length of each section of the central emulsion detonation tube 1 according to the thickness of the hard rock. At the same time, the rotating block 9 on the surface of the connecting tube 8, through the cooperation of the mounting plate 10, the first spring 11, and the limiting clamp 12, can achieve structural adjustment and limiting, improving the device's ease of installation, structural stability, and detonation effect transmission efficiency.

[0017] During the loading stage, the detonating cord transmission tube 2 is inserted into the central emulsion explosive enhancement tube 1 of the device. Simultaneously, the length of each section of the central emulsion explosive enhancement tube 1 is adjusted according to the thickness of the hard rock. Emulsion paste is then filled into each section of the central emulsion explosive enhancement tube 1. The central emulsion explosive enhancement tube 1 is lowered to each hard rock layer using the suspension mechanism 5. The opening-type borehole wall fixing mechanism 4 is then opened, utilizing the frictional damping effect between the fixing mechanism and the borehole wall to achieve high-strength fixation between the device and the borehole wall, ensuring that the device position does not move or deviate during the loading of bulk explosives. At detonation, a detonator is inserted at the detonating cord transmission tube 2 at the top of the device to activate the detonating cord. After the detonating cord transmission tube 2 detonates, it ignites the emulsion explosive in the central emulsion explosive enhancement tube 1 through the detonation wave transmission hole 3, relaying the ignition of other bulk explosives in the borehole, providing stronger explosive energy to the hard rock layers, thereby intensifying the fragmentation of hard rock and reducing the formation of large fragments.

[0018] Limiting rods 13 are installed on both sides of the surface of the limiting hoop 12. The limiting rods 13 penetrate the surface of the mounting plate 10 and can limit the limiting hoop 12 so that the limiting hoop 12 will not deviate.

[0019] All connecting ends of the central emulsion detonation tube 1 are equipped with sealing rings 14. The inner ring of the sealing ring 14 is in close contact with the surface of the detonating cord transmission tube 2. The sealing ring 14 can effectively prevent external substances from entering the interior of the central emulsion detonation tube 1, avoid damage to the detonating cord transmission tube 2, and ensure the detonation effect of the entire device.

[0020] Please see Figure 4 The surface of the support-type hole wall fixing mechanism 4 is equipped with a mounting rod 15, and a movable sleeve 16 is sleeved on the surface of the mounting rod 15. Please refer to [link / reference]. Figure 5 The surface of the movable sleeve 16 is evenly distributed with mounting blocks 17. Please refer to [link / reference]. Figure 4Each mounting block 17 is equipped with a support rod 18 via a rotating shaft, allowing the support rod 18 to rotate flexibly. When the open-type hole wall fixing mechanism 4 is working, the angle of the support rod 18 can be adjusted according to the actual situation of the hole wall to better fit the hole wall and enhance the fixing effect.

[0021] The surface of the openable hole wall fixing mechanism 4 is movably fitted with mounting sleeves 19 at positions corresponding to the support rods 18. The top ends of the support rods 18 are inserted into the interior of the mounting sleeves 19. The mounting sleeves 19 and the top ends of the support rods 18 are fitted with clearance, which ensures that the top ends of the support rods 18 can be smoothly inserted into the mounting sleeves 19, and also provides a certain buffer space when the support rods 18 are under force, reducing stress concentration caused by rigid connection, improving the reliability of the connection between the support rods 18 and the mounting sleeves 19, and extending the service life of the entire openable hole wall fixing mechanism 4.

[0022] Please see Figure 6 The inner cavity of the mounting rod 15 is evenly provided with second springs 20. Each output end of the second spring 20 is equipped with a limit head 21. When the movable sleeve 16 moves to a specific position, the limit head 21 pops out under the action of the second spring 20, preventing the movable sleeve 16 from continuing to move, thereby controlling the degree of expansion of the support rod 18 and ensuring that the open-type hole wall fixing mechanism 4 can be stably fixed on the hole wall.

[0023] During operation: In the charging stage, the detonating cord transmission tube 2 is inserted into the central emulsion-enhancing tube 1. Based on the thickness of the hard rock, the length of the central emulsion-enhancing tube 1 is adjusted using the screw-fit structure of the first connecting cylinder 6 and the second connecting cylinder 7 via the connecting pipe 8. The emulsion paste is then filled into the tube. The sealing ring 14 prevents external substances from entering and damaging the detonating cord transmission tube 2. The central emulsion-enhancing tube 1 is lowered to the hard rock layer using the suspension mechanism 5. The opening-type hole wall fixing mechanism 4 is opened, and the movable sleeve 16 moves on the mounting rod 15, causing the support rod 18, connected via the mounting block 17 and the rotating shaft, to rotate. The top of the support rod 18 is inserted into the mounting sleeve 19, and the movable sleeve 16 moves... When the device moves to a specific position, the second spring 20 inside the mounting rod 15 pushes the limiting head 21 to pop out, controlling the extent of the extension of the support rod 18. High-strength fixation is achieved by using the fixing mechanism and friction damping against the borehole wall. During detonation, a detonator is installed at the detonating cord transmission tube 2 at the top of the device to activate the detonating cord. The detonating cord transmission tube 2 detonates the emulsion explosive in the central emulsion boosting tube 1 through the detonation wave transmission hole 3, and then ignites other bulk explosives in the borehole. The rotating block 9 on the surface of the connecting pipe 8, through the mounting plate 10, the first spring 11, and the limiting clamp 12, works with the limiting rod 13 to achieve structural adjustment and limitation, improving the ease of installation, structural stability, and detonation effect transmission efficiency of the device.
