Description

Technical Field

[0001] The present invention relates to the technical field of material loading; specifically, the present invention relates to a precise loading device and a shaped charge tube with measurable spacing. Background Art

[0002] In traditional blasting, when the explosive explodes, it will generate high-temperature and high-pressure gases, which will diffuse in all directions at an extremely fast speed. During the diffusion process, the gases will generate a strong impact force and vibration on the building, resulting in the destruction of the building or other objects. As a new type of blasting device, the shaped charge tube has two grooves in the horizontal direction of the tube wall. After filling the explosive, when it explodes, the energy will achieve an effect similar to cutting a knife along the horizontal direction, thus effectively controlling the blasting direction. Traditional shaped charge tubes generally adopt a closed circular PVC tube structure, and there are the following problems in construction: (1) The installation and fixation quality of the shaped charge tube is greatly affected by human factors: After the shaped charge tube is filled with explosive, it is necessary to fix the filled shaped charge tube on the bamboo strip in advance according to the interval charge spacing, and at the same time, it is necessary to ensure that the directions of the shaped charge grooves in the shaped charge tubes on the same bamboo strip must be kept consistent. The uncertainty of manual operation will affect the overall installation and fixation effect. If the directions are inconsistent, it is impossible to ensure the same-direction cutting, and more serious over-excavation or under-excavation will occur; (2) The installation direction of the shaped charge tube in the hole is greatly affected by human factors: When sending the explosive into the blast hole with the bamboo strip, it is necessary to ensure that the cutting direction of the shaped charge groove in the shaped charge tube is along the tunnel contour direction. However, during the process of sending the explosive, it is often difficult for workers to judge the direction of the shaped charge groove. If the directions are inconsistent, it is impossible to ensure along the tunnel contour direction, and more serious over-excavation will occur. Summary of the Invention

Detailed implementation manners

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figures 1 to 3 shown, a precise loading device is used for precise loading operations on the energy-gathering tube 1 connected by the scale 2 and having planes 1-4 on both sides. It includes a bracket 3 and a clamping assembly 4. The clamping assembly 4 includes a clamping plate 4-1, a sliding seat 4-2 and a positioning ring 4-3. There are two clamping plates 4-1 and two positioning rings 4-3, and both are arranged in a semi-circular shape. The two positioning rings 4-3 can be combined into a complete ring. The two clamping plates 4-1 are respectively slidably installed on the two positioning rings 4-3. The clamping plate 4-1 can contact the plane 1-4 and can be inserted into the blast hole. The bracket 3 includes a bottom plate 3-1 and limiting rods 3-2. There are two limiting rods 3-2, and both are slidably installed on the bottom plate 3-1. The two ends of the sliding seat 4-2 are respectively slidably installed on the two limiting rods 3-2.

[0020] During use, first control the distance between the two clamping plates 4-1, make the clamping plate 4-1 contact the plane 1-4, and clamp the plane 1-4 with the clamping plate 4-1. By controlling the height of the sliding seat 4-2 on the limiting rod 3-2, make the height of the circular ring correspond to that of the blast hole, and ensure that the end of the clamping plate 4-1 can be inserted into the blast hole.

[0021] When inserting the shaped charge tube 1 into the blast hole, first insert the clamping plate 4-1 horizontally into the blast hole to limit the farthest distance on both lateral sides of the shaped charge tube 1. Subsequently, withdraw the clamping plate 4-1 from the blast hole, rotate the clamping plate 4-1 one full circle on the positioning ring 4-3, and then insert the clamping plate 4-1 vertically into the blast hole to limit the farthest positions on both longitudinal sides of the shaped charge tube 1, ensuring that when inserting, the shaped charge tube 1 does not contact the inner wall of the blast hole, preventing the influence of the frictional force of the blast hole inner wall during insertion and avoiding the situation where the distance between adjacent shaped charge tubes 1 changes, making the blasting more accurate. When inserting the shaped charge tube 1, inserting the clamping plate 4-1 vertically into the blast hole can, compared with the way of inserting the clamping plate 4-1 horizontally, prevent the shaped charge tube 1 from being affected by its own gravity during insertion, resulting in the shaped charge tube 1 at the farthest end from the blast hole deflecting downward, causing relative displacement between the shaped charge tube 1 and the clamping plate 4-1 and changing the insertion distance.

[0022] As Figure 4 and Figure 5 shown, the clamping plate 4-1 includes a first part 4-11 and a second part 4-12. The first part 4-11 can contact the plane 1-4, the first part 4-11 can be inserted into the blast hole, and the width direction of the first part 4-11 is parallel to the plane 1-4. The first part 4-11 is set as a long strip shape, the second part 4-12 is set as a hollow rectangular frame, the height direction of the second part 4-12 is parallel to the plane 1-4, the length direction of the second part 4-12 is perpendicular to the plane 1-4, the first part 4-11 is fixedly installed at one end of the second part 4-12 close to the blast hole, and the surface of the first part 4-11 close to the shaped charge tube 1 and the surface of the second part 4-12 close to the shaped charge tube 1 are arranged in the same plane.

[0023] Before inserting the shaped charge tube 1 into the blast hole, first make the second part 4-12 contact the plane 1-4 of the first shaped charge tube 1, and insert the first part 4-11 into the blast hole. After the first part 4-11 is inserted into the blast hole, let the shaped charge tube 1 move from within the range of the second part 4-12 to within the range of the first part 4-11, so that the shaped charge tube 1 can be stably inserted into the blast hole. At this time, the shaped charge tube 1 does not contact the inner wall of the blast hole. When inserting the shaped charge tube 1, it can ensure that the distance between adjacent shaped charge tubes 1 does not change, ensuring the accuracy of blasting.

[0024] As Figure 4As shown, a rotary belt 4-4 is drivingly installed on the outer surface of the clamping plate 4-1. The outer surface of the rotary belt 4-4 can contact the plane 1-4. One end of the first part 4-11 away from the second part 4-12 is rotatably installed with a first runner 4-5. One end of the second part 4-12 fixedly connected to the first part 4-11 is rotatably installed with a second runner 4-6. Third runners 4-7 are rotatably installed at the ends of the second part 4-12 away from the first part 4-11. Both the first runner 4-5 and the third runner 4-7 can contact the inner surface of the rotary belt 4-4, and the second runner 4-6 can contact the outer surface of the rotary belt 4-4 and press the rotary belt 4-4 into a taut state.

[0025] When the second part 4-12 contacts the plane 1-4, bring the two second parts 4-12 closer to each other so that the second part 4-12 is in close contact with the plane 1-4, and clamp the energy-gathering tube 1 within the range of the second part 4-12. Then insert the first part 4-11 into the blast hole. At this time, the rotary belt 4-4 passes through the first runner 4-5, the second runner 4-6, and the third runner 4-7, enabling the rotary belt 4-4 to rotate on the outer surface of the clamping plate 4-1 while maintaining a straight state. When the rotary belt 4-4 rotates, using the clamping force and frictional force of the two-side rotary belt 4-4, the energy-gathering tube 1 is transported along the rotation direction of the rotary belt 4-4 into the blast hole, ensuring that the distance between adjacent two energy-gathering tubes 1 remains unchanged during insertion.

[0026] As Figure 5 shown, teeth 4-8 are fixedly installed on both sides of the first runner 4-5, the second runner 4-6, and the third runner 4-7. Tooth grooves 4-41 meshing with the teeth 4-8 are formed on both sides of the rotary belt 4-4.

[0027] When the third runner 4-7 rotates, it can drive the teeth 4-8 to rotate. When the teeth 4-8 rotate, they can drive the tooth grooves 4-41 to move, thereby enabling the rotary belt 4-4 to rotate on the surface of the clamping plate 4-1 while maintaining a straight state. When the teeth 4-8 rotate forward, it can drive the rotary belt 4-4 to rotate forward. When the first part 4-11 is inserted into the blast hole, rotate the teeth 4-8 forward, causing the rotary belt 4-4 to drive the energy-gathering tube 1 to be inserted into the blast hole. At this time, the clamping plate 4-1 is in close contact with the plane 1-4, making the frictional force on the side of the rotary belt 4-4 close to the plane 1-4 greater than the frictional force on the side of the rotary belt 4-4 away from the plane 1-4, enabling the energy-gathering tube 1 to be tractioned by the rotary belt 4-4 on the plane 1-4 and stably transported into the blast hole. After the energy-gathering tube 1 is inserted into the blast hole, cancel the clamping force between the clamping plate 4-1 and the plane 1-4, and bring the rotary belt 4-4 into contact with the inner wall of the blast hole. At this time, reverse the rotation of the teeth 4-8. At this time, the frictional force between the outer wall of the energy concentrating tube 1 and the inner wall of the blast hole is greater than the frictional force on the side of the rotating belt 4-4 close to the plane 1-4, which can cause the side of the rotating belt 4-4 close to the plane 1-4 to fit and rotate along the inner wall of the blast hole. The clamping plate 4-1 is withdrawn from the blast hole along the rotation direction of the rotating belt 4-4. At this time, the rotating belt 4-4 does not contact the energy concentrating tube 1, which can keep the distance between two adjacent energy concentrating tubes 1 unchanged when the clamping plate 4-1 is withdrawn, ensuring the blasting accuracy.

[0028] As Figures 4 to 6 shown, guide rails 4-13 are fixedly installed on both sides in the width direction of the first part 4-11. Blocks are fixedly installed at both ends of the guide rails 4-13. An arc groove 4-31 is formed on the inner surface of the positioning ring 4-3. A sliding block 4-32 is slidably installed in the arc groove 4-31. A clamping groove 4-33 is formed on the sliding block 4-32. The guide rail 4-13 penetrates through the clamping groove 4-33, and the sliding block 4-32 can slide on the guide rail 4-13.

[0029] When the clamping plate 4-1 moves, the sliding block 4-32 slides on the guide rail 4-13, enabling the first part 4-11 to be inserted into and withdrawn from the blast hole stably. When the sliding block 4-32 moves to both ends of the guide rail 4-13, it is blocked by the blocks, preventing the sliding block 4-32 from falling off the guide rail 4-13; After the energy concentrating tube 1 is inserted into the blast hole, adjust the orientation of the first scale 2-1 in the circumferential direction of the blast hole. The first scale 2-1 drives the energy concentrating tube 1 to rotate, enabling the plane 1-4 to drive the clamping plate 4-1 to rotate in the blast hole. The clamping plate 4-1 drives the sliding block 4-32 to slide in the arc groove 4-31, ensuring that the clamping plate 4-1 can maintain the clamping state when adjusting the orientation of the V-shaped energy concentrating groove, preventing the distance between two adjacent energy concentrating tubes 1 from changing during rotation; Subsequently, withdraw the scale 2 from the energy concentrating tube 1. At this time, the clamping plate 4-1 maintains the clamping effect on the energy concentrating tube 1, ensuring that the distance between two adjacent energy concentrating tubes 1 remains unchanged when the scale 2 is withdrawn, achieving the effect of recovering the scale 2. Then, withdraw the clamping plate 4-1 from the blast hole to complete the operation of inserting the energy concentrating tube 1 into the blast hole.

[0030] As Figure 4 shown, a driving motor 4-15 is fixedly installed on the third runner 4-7 farthest from the first part 4-11. An installation frame 4-16 is fixedly installed on the outer wall of the driving motor 4-15. The installation frame 4-16 is fixedly installed on the inner surface of the second part 4-12. There are two driving motors 4-15, and the two driving motors 4-15 are fixedly installed on the two second parts 4-12.

[0031] Start the drive motor 4-15 so that the drive motor 4-15 drives the third runner 4-7 to rotate. The third runner 4-7 drives the rotary belt 4-4 to rotate. When the rotary belt 4-4 drives the energy concentrating tube 1 to insert into the blast hole, ensure that the distance between two adjacent energy concentrating tubes 1 remains unchanged. The rotary belt 4-4 moves on the inner wall of the blast hole, facilitating the extraction of the clamping plate 4-1 from the inside of the blast hole.

[0032] As Figure 2 As shown, at the bottom ends of two positioning rings 4-3, connecting rods 4-21 are fixedly installed. At the bottom ends of the connecting rods 4-21, sliding plates 4-22 are fixedly installed. The sliding plates 4-22 are sleeved on the sliding seats 4-2. Between the bottom ends of the two sliding plates 4-22, a bidirectional threaded sleeve 4-23 is provided. At both ends of the bidirectional threaded sleeve 4-23, threaded rods 4-24 are rotatably installed. The ends of the two threaded rods 4-24 far from the bidirectional threaded sleeve 4-23 are respectively fixedly installed at the bottom ends of the two sliding plates 4-22.

[0033] After the energy concentrating tubes 1 are assembled, place the plane 1-4 of the first energy concentrating tube 1 within the range of the second part 4-12. At this time, rotate the bidirectional threaded sleeve 4-23 to drive the threaded rods 4-24 on both sides to approach each other, enabling the sliding plates 4-22 on both sides to drive the connecting rods 4-21 to approach each other, achieving the effect of the second part 4-12 clamping the energy concentrating tube 1, and at the same time achieving the effect of assembling the two positioning rings 4-3 into a complete ring.

[0034] As Figure 1 and Figure 3 As shown, at both ends of the sliding seat 4-2, handles 4-25 are fixedly installed. The distance between the handles 4-25 is greater than the distance between the two drive motors 4-15.

[0035] During the alignment of the positioning ring 4-3 with the blast hole, hold the handle 4-25 to control the height of the sliding seat 4-2 on the limiting rod 3-2, corresponding to the height of the positioning ring 4-3 and the blast hole. When the end of the first part 4-11 inserts into the blast hole, blocked by the blast hole, the positioning ring 4-3 can drive the sliding plate 4-22 to move on the sliding seat 4-2, facilitating the positioning ring 4-3 to adapt to the hole laterally. When the subsequent energy concentrating tube 1 inserts into the blast hole, it can detect the inside of the blast hole in advance to prevent the friction force on the inner wall of the blast hole from blocking the energy concentrating tube 1 when inserting, resulting in a change in the distance between two adjacent energy concentrating tubes 1.

[0036] As Figure 2 As shown, on the top surface of the bottom plate 3-1, a U-shaped moving plate 3-3 is provided. The bottom ends of the two limiting rods 3-2 are respectively fixedly installed on both sides of the moving plate 3-3. At both ends of the moving plate 3-3, limiting plates 3-4 are fixedly installed. On both sides of the moving plate 3-3, limiting sleeves 3-5 are slidably installed. The limiting sleeves 3-5 are fixedly installed on the top surface of the bottom plate 3-1.

[0037] Before inserting the first part 4-11, the sliding block 4-32 is located at one end of the guide rail 4-13 close to the first runner 4-5 and contacts the stop block. Then, pull the handle 4-25, so that the limit rod 3-2 drives the moving plate 3-3 to slide on the bottom plate 3-1. When the central part of the moving plate 3-3 contacts the limit sleeve 3-5, the first part 4-11 moves away from the blast hole, facilitating the adjustment of the height of the first part 4-11. After the height adjustment is completed, push the handle 4-25, so that the moving plate 3-3 slides on the bottom plate 3-1 and the limit plate 3-4 contacts the limit sleeve 3-5. At this time, the end of the first part 4-11 can be inserted into the blast hole, providing a guiding function for the subsequent complete insertion of the first part 4-11 into the blast hole.

[0038] When inserting the shaped charge tubes 1, the distance between two adjacent shaped charge tubes 1 can be kept unchanged, and the distance between two adjacent shaped charge tubes 1 can also be kept unchanged when recovering the scale 2, ensuring the effect of blasting accuracy.

[0039] As Figure 7 and Figure 8 shown, in the second embodiment, a shaped charge tube capable of measuring the distance is accurately loaded into the blast hole by applying the above-mentioned precise loading device, including a plurality of shaped charge tubes 1 and a scale 2 for distributing the plurality of shaped charge tubes 1 at a preset distance. The scale 2 is arranged on the surface of the shaped charge tube 1. Two V-shaped shaped charge grooves are arranged in the shaped charge tube 1. Plane 1-4 is arranged on both sides of the surface of the shaped charge tube 1, and the two planes 1-4 correspond to the positions of the two V-shaped shaped charge grooves respectively.

[0040] A groove 1-1 is arranged on the shaped charge tube 1. The groove 1-1 includes a first groove 1-2 and a second groove 1-3. The first groove 1-2 is located between the two V-shaped shaped charge grooves, and the radial direction of the first groove 1-2 is perpendicular to the radial direction of the tops of the two V-shaped shaped charge grooves. There are two second grooves 1-3, and they are mirror-symmetrically arranged on the sides of the two V-shaped shaped charge grooves away from the first groove 1-2. The scale 2 includes a first scale 2-1 and a second scale 2-2. The first scale 2-1 can be inserted into the first groove 1-2. There are two second scales 2-2, and the two second scales 2-2 are respectively inserted into the two second grooves 1-3.

[0041] When in use, first insert the two second scales 2-2 into the two second grooves 1-3 respectively, and control the distance between two adjacent shaped charge tubes 1 by observing the scale on the scale 2. After installing a plurality of shaped charge tubes 1 on the second scale 2-2, then install the explosive cartridge into the shaped charge tube 1 and install the shaped charge cavity at the bottom end of the shaped charge tube 1. After the energy concentrating cavities are installed, the first scale 2-1 penetrates through the first grooves 1-2 on multiple energy concentrating tubes 1, and the first scale 2-1 is flush with the second scale 2-2. After the insertion of the first scale 2-1 and the second scale 2-2 is completed, the scale 2 and the energy concentrating tubes 1 are inserted into the blast hole together, so that the spacing between the multiple energy concentrating tubes 1 inserted into the blast hole can be controlled.

[0042] The technical scope of the present invention is not limited to the content in the above specification. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the scope of the present invention.
