Description

Technical Field

[0001] The invention relates to the technical field of mining equipment, in particular to a charging device for multi-point blasting in mining. Background Art

[0002] In the process of mining, people need to use explosives to blast the mines, and then clean them up mechanically at any time. In order to improve the efficiency of blasting the mines with explosives, people will use multi-point explosive tubes to blast the mines. Before using the multi-point explosive tubes, it is necessary to install explosives in a directional manner inside the multi-point explosive tubes, and in order to ensure the safety of filling the explosive tubes with explosives, it is necessary to limit the multi-point explosive tubes. However, there are still certain defects in the existing method of loading explosives in the multi-point explosive tubes, such as: The utility model announcement number CN219368556U discloses a multi-point shaped charge blasting charge structure. The sealing plate can assist in shielding and sealing the outer side of the through hole during use. On the one hand, it can maintain the dryness of the inner tube and the outer tube for a long time, thereby maintaining the performance of the explosive. On the other hand, it can assist in protecting the shaped charge tube in the inner tube when installing the explosive, thereby improving its installation convenience to avoid squeezing the shaped charge tube, and also avoiding the situation where the explosive is damp due to damage to the water hose. Moreover, since it is made of plastic material and a cross groove is arranged on the front side, the entire sealing plate is relatively fragile. When an explosion occurs, it will instantly break and melt, thereby maintaining the normal shaped charge explosion effect, and still can assist in guiding to maintain its normal performance, so that the charge structure is more stable as a whole compared with the existing technical solutions, and is more convenient and safe to store and use, and has strong practicality. In the above document, the structure needs to clamp and limit the charge tube during use, and in the process of limiting the charge tube, it is necessary to first place the two sets of bases in correspondence, and then turn the two sets of knobs to complete the limiting of the multi-point explosive tube, while the structure can only be used for limiting the position of a single explosive tube, and in the process of rotating the multi-point explosive tube, the structure needs to manually turn the two sets of knobs in sequence, and before use, the positions of the two sets of bases need to be adjusted to a suitable position before use, which increases the complexity of the use of the structure and brings many inconveniences; Another example is the utility model announcement number CN112393656A which discloses a multi-point shaped charge structure. The outer layer of the casing of this technical solution is made of PVC material and is provided with multiple installation holes along the axial direction, so that the casing structure is similar to a slit tube. During the explosion, the shaped charge tube on the installation hole causes the rock at the installation hole to be subjected to a larger explosion load earlier, resulting in the radial cracks at the location expanding before other areas, which plays a guiding role in the overall explosion forming. In addition, the charge cap of this technical solution is an inwardly concave cone with a top angle of 90°. When the detonation wave advances to the conical part, its detonation products fly out in a direction perpendicular to the surface of the cone hole and gather on the central axis of the cone, which can make the explosion energy more concentrated and the explosion destructive effect better. In the above-mentioned document, during the use of the structure, it is necessary to place the explosive tube inside the structure to load the explosives, and it is necessary to align the holes inside the structure with the holes inside the explosive tube, and the main body of the structure is a columnar structure, which may cause the structure and the charging tube to roll easily during use, which may easily lead to low stability of the structure and bring inconvenience to use.

[0016] In the process of mining, the mine is usually blasted through explosive tubes. Before blasting, the explosives need to be installed inside the explosive channel, and the explosive tubes need to be fixed during the process to ensure the safety of the charge. When using the multi-point blasting method for mining, the device is first placed at the position where work is required. After the device is placed at the required position, it can be used. The charge tube needs to be limited at the upper end of the support plate 2. In this process, two groups of charge tubes need to be placed between the fixed clamping plate 3 and the sliding clamping plate 4. In this process, the guide plate 5 will guide the charge tube to prevent the charge tube from deviating. After the two groups of charge tubes are placed, the turntable assembly 10 can be rotated. During the rotation of the turntable assembly 10, the bevel gear 2 11 will be driven to rotate, and the cone Gear 2 11 will drive the rotating rod 6 to rotate through bevel gear 1 8, and a pulley structure is provided on the outer side of the two groups of rotating rods 6, so that the two groups of rotating rods 6 can be rotated, and the rotating rods 6 will cause the two groups of moving cylinders 7 to move away from each other during the rotation, and the moving cylinders 7 will push the two groups of sliding splints 4 to move during the movement, and the sliding splints 4 will cooperate with the fixed splints 3 to clamp the charge tube during the movement, and the charge tube can be filled with explosives at this time. At this point, the clamping process of the charge tube is completed, which effectively improves the convenience of using the device.

[0017] Embodiment 2: This embodiment is as follows Figure 2-Figure 9 As shown, in order to solve the problem that the existing method needs to manually remove the charge tube automatically during the process, the process of automatically removing the charge tube from the inside of the device is disclosed, and the method can automatically eject the charge tube safely. The specific content is as follows: A limit rod 12 is rotatably mounted inside the support plate 2, and a driven rod 14 is rotatably mounted on the lower end of the support plate 2, and a lifting member 15 is threadedly mounted on the outer sides of the limit rod 12 and the driven rod 14, and a bevel gear 3 13 is fixedly mounted on the upper end of the limit rod 12, and the bevel gear 3 13 is meshedly connected with the bevel gear 1 8; Two sets of lifting holes 16 are provided inside the support plate 2, and a lifting plate 17 is slidably installed inside the lifting holes 16, and a fixed clamping block 18 is fixedly installed on the upper end of the lifting plate 17, and the lower end of the lifting plate 17 is fixedly connected to the lifting member 15; A sliding clamp 19 is slidably installed on the upper end of the lifting plate 17, and a connecting spring 20 is fixedly installed between the sliding clamp 19 and the lifting plate 17, and a connecting rope 21 is fixedly installed on the end of the sliding clamp 19 away from the connecting spring 20, and the connecting rope 21 is fixedly connected to the inside of the support plate 2.

[0018] After the device completes charging the charge tube, it is necessary to rotate the turntable assembly 10 in the opposite direction. At this time, the two sets of sliding clamps 4 will approach each other, and the bevel gear 2 11 will drive the bevel gear 1 8 to rotate, and the bevel gear 1 8 will drive the bevel gear 3 13 to rotate, and the bevel gear 3 13 will drive the limit rod 12 to rotate, and the outer sides of the limit rod 12 and the driven rod 14 are also sleeved with a pulley structure, so that the limit rod 12 and the driven rod 14 can rotate synchronously, and the limit rod 12 and the driven rod 14 rotate, so that the lifting member 15 can push the two sets of lifting plates 17 to move upward, and the lifting plates 17 move upward. During the upward movement, it will contact the charge tube and push the charge tube upward, and then the charge tube can be separated from the support plate 2. During the upward movement of the lifting plate 17, the support plate 2 will pull the sliding clamp block 19 to slide on the upper end of the lifting plate 17 through the connecting rope 21. At this time, the connecting spring 20 will be stretched and expanded by the sliding clamp block 19, so that the sliding clamp block 19 cooperates with the fixed clamp block 18 to clamp the outer side of the charge tube, avoiding the charge tube from slipping due to tilting during the placement of the device, and at the same time facilitating the removal of the charge tube from the inside of the device, effectively ensuring the convenience of using the device.

[0019] Embodiment 3: This embodiment is as follows Figure 1-Figure 4 and Fig.10 As shown, in order to solve the problem that the existing method requires manual handling during use, the method is disclosed to realize the process of lifting and lowering the limiting roller inside the device, and realize the effect of facilitating the movement and transportation of the device, and the specific contents are as follows: Two sets of moving plates 25 are slidably mounted inside the support base 1, and a connecting plate 26 is fixedly mounted on the upper end of the moving plate 25, and a moving roller 30 is rotatably mounted on the lower end of the moving plate 25, and a connecting block 27 is fixedly mounted on one side of the connecting plate 26 close to the middle position of the support base 1; A driving rod 22 and a threaded rod 28 are rotatably mounted on the upper end of the support base 1, and two sets of bevel gears 24 are fixedly mounted on the outer side of the driving rod 22, and a bevel gear 5 29 is fixedly mounted on the lower end of the threaded rod 28. At the same time, a turntable assembly 23 is fixedly mounted on one end of the driving rod 22, the bevel gear 4 24 is meshedly connected with the bevel gear 5 29, and the threaded rod 28 is threadedly connected to the connecting block 27.

[0020] Before using the multi-point blasting structure for mining, the device needs to be transported to the required position. During the transportation of the device, the turntable assembly 23 needs to be rotated, and the turntable assembly 23 will drive the bevel gear 4 24 to rotate through the driving rod 22. The rotation of the bevel gear 4 24 will cause the bevel gear 5 29 meshing with it to rotate, and the bevel gear 5 29 will drive the threaded rod 28 to rotate, and then the connecting block 27 can move downward, and then the connecting plate 26 can push the moving plate 25 to move downward, and the moving plate 25 will drive the moving roller 30 to move downward and contact the ground, and then the support base 1 can move upward and separate from the ground, and then the device can be driven to move by rolling through the moving roller 30. After the device moves to the required position, rotating the turntable assembly 23 in the opposite direction can make the support base 1 contact the ground again, thereby ensuring the stability of the device support and increasing the overall practicality.
