Description

Technical Field

[0001] The present invention relates to the technical field of material filling; in particular, the present invention relates to a precise filling device and an energy-gathering tube with measurable spacing. Background Art

[0002] In traditional blasting, when explosives explode, they produce high-temperature, high-pressure gases that diffuse in all directions at an extremely fast rate. During the diffusion process, the gases exert a violent impact and vibration on buildings, causing damage to buildings or other objects. As a new type of blasting device, the energy-gathering tube has two grooves in the horizontal direction of the tube wall. After the explosives are loaded, when the explosion occurs, the energy will achieve a horizontal cutting effect, thereby achieving effective control of the blasting direction. Traditional energy-gathering tubes generally use a closed circular PVC tube structure, which has the following problems during construction:

[0003] (1) The quality of the installation and fixation of the energy-gathering tube is greatly affected by human factors: after the energy-gathering tube is loaded, it is necessary to fix the loaded energy-gathering tube on the bamboo piece in advance according to the interval of the charging interval. At the same time, it is necessary to ensure that the direction of the energy-gathering groove in the energy-gathering tube on the same bamboo piece must be consistent. The uncertainty of manual operation will affect the overall installation and fixation effect. If the direction is inconsistent, the same direction cutting cannot be guaranteed, which will result in more serious over-excavation or under-excavation;

[0004] (2) The installation direction of the energy-gathering tube in the hole is greatly affected by human factors: when using bamboo strips to deliver explosives into the blasthole, it is necessary to ensure that the cutting direction of the energy-gathering groove in the energy-gathering tube is along the direction of the tunnel contour. However, during the delivery process, it is often difficult for workers to judge the direction of the energy-gathering groove. If the direction is inconsistent, it cannot be guaranteed to be along the direction of the tunnel contour, which will cause more serious over-excavation. Summary of the Invention

DETAILED DESCRIPTION

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 3As shown, a precise loading device is used for precisely loading an energy-gathering tube 1 connected by a scale 2 and provided with planes 1-4 on both sides, comprising a bracket 3 and a clamping assembly 4, the clamping assembly 4 comprising a splint 4-1, a sliding seat 4-2 and a positioning ring 4-3, two splints 4-1 are provided, two positioning rings 4-3 are provided, and both are arranged in a semicircular shape, the two positioning rings 4-3 can be combined into a complete circular ring, the two splints 4-1 are respectively slidably mounted on the two positioning rings 4-3, the splints 4-1 can contact with the plane 1-4, and the splints 4-1 can be inserted into the blast hole, the bracket 3 comprises a base plate 3-1 and a limit rod 3-2, two limit rods 3-2 are provided, the two limit rods 3-2 are both slidably mounted on the base plate 3-1, and the two ends of the sliding seat 4-2 are respectively slidably mounted on the two limit rods 3-2.

[0030] When in use, first control the distance between the two splints 4-1, make the splint 4-1 contact with the plane 1-4, and clamp the plane 1-4 with the splint 4-1. By controlling the height of the sliding seat 4-2 on the limit rod 3-2, the height of the ring is matched with the blast hole, and the end of the splint 4-1 can be inserted into the blast hole.

[0031] When inserting the energy-gathering tube 1 into the blasthole, first insert the splint 4-1 into the blasthole in a horizontal direction to limit the maximum distance between the two sides of the energy-gathering tube 1 in the horizontal direction. Then, pull the splint 4-1 out of the blasthole, rotate the splint 4-1 on the positioning ring 4-3 once, and then insert the splint 4-1 into the blasthole in a vertical direction to limit the maximum distance between the two sides of the energy-gathering tube 1 in the longitudinal direction. This ensures that the energy-gathering tube 1 does not contact the inner wall of the blasthole during insertion, prevents the energy-gathering tube 1 from being affected by the friction force of the inner wall of the blasthole during insertion, and prevents the distance between two adjacent energy-gathering tubes 1 from changing, making blasting more accurate.

[0032] When inserting the energy-gathering tube 1, the splint 4-1 is inserted vertically into the blasthole. This insertion method, relative to the horizontal insertion method of the splint 4-1, can prevent the energy-gathering tube 1 from being affected by its own gravity during insertion, causing the energy-gathering tube 1 farthest from the blasthole to deflect downward, resulting in relative displacement between the splint 4-1 and the insertion distance.

[0033] like Figure 4 and Figure 5As shown, the splint 4-1 includes a first part 4-11 and a second part 4-12, the first part 4-11 can contact with 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 to a long strip, the second part 4-12 is set to 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 on the end of the second part 4-12 close to the blast hole, and the side of the first part 4-11 close to the energy-gathering tube 1 and the side of the second part 4-12 close to the energy-gathering tube 1 are coplanar.

[0034] Before the energy-gathering tube 1 is inserted into the blasthole, the second part 4-12 is first brought into contact with the plane 1-4 of the first energy-gathering tube 1, and the first part 4-11 is inserted into the blasthole. After the first part 4-11 is inserted into the blasthole, the energy-gathering tube 1 is moved from the range of the second part 4-12 to the range of the first part 4-11, so that the energy-gathering tube 1 can be stably inserted into the blasthole. At this time, the energy-gathering tube 1 does not contact the inner wall of the blasthole. When the energy-gathering tube 1 is inserted, it can be ensured that the distance between two adjacent energy-gathering tubes 1 will not change, thereby ensuring the accuracy of blasting.

[0035] like Figure 4 As shown, the outer surface of the splint 4-1 is transmission-installed with a revolving belt 4-4, and the outer surface of the revolving belt 4-4 can contact with the plane 1-4. The first part 4-11 is rotatably installed on the end away from the second part 4-12 with the first wheel 4-5, and the second part 4-12 is rotatably installed on the end fixedly connected to the first part 4-11 with the second wheel 4-6. The end of the second part 4-12 away from the first part 4-11 is rotatably installed with the third wheel 4-7. Both the first wheel 4-5 and the third wheel 4-7 can contact with the inner surface of the revolving belt 4-4, and the second wheel 4-6 can contact with the outer surface of the revolving belt 4-4 and press the revolving belt 4-4 into a taut state.

[0036] When the second parts 4-12 are in contact with the plane 1-4, the two second parts 4-12 are brought closer to each other so that the second parts 4-12 are in close contact with the plane 1-4, and the energy-gathering tube 1 is clamped within the range of the second parts 4-12. Then, the first part 4-11 is inserted into the blasthole. At this time, the revolving belt 4-4 passes through the first rotating wheel 4-5, the second rotating wheel 4-6 and the third rotating wheel 4-7, so that the revolving belt 4-4 can remain stretched and rotate on the outer surface of the clamping plate 4-1.

[0037] When the rotating belt 4-4 rotates, the clamping force and friction force of the rotating belts 4-4 on both sides are used to transport the energy-gathering tube 1 into the blasthole along the rotating direction of the rotating belt 4-4, ensuring that the distance between two adjacent energy-gathering tubes 1 does not change during insertion.

[0038] like Figure 5 As shown, teeth 4-8 are fixedly installed on both sides of the first rotating wheel 4-5, the second rotating wheel 4-6 and the third rotating wheel 4-7, and tooth grooves 4-41 that mesh with the teeth 4-8 are opened on both sides of the rotating belt 4-4.

[0039] When the third rotating wheel 4-7 rotates, it can drive the teeth 4-8 to rotate, and when the teeth 4-8 rotates, it can drive the tooth groove 4-41 to move, so that the revolving belt 4-4 rotates while keeping it stretched on the surface of the clamping plate 4-1;

[0040] When the teeth 4-8 rotate forward, they can drive the rotating belt 4-4 to rotate forward. When the first part 4-11 is inserted into the blasthole, the teeth 4-8 rotate forward, so that the rotating belt 4-4 drives the energy-gathering tube 1 to be inserted into the blasthole. At this time, the clamping plate 4-1 is in close contact with the plane 1-4, so that the friction force of the side of the rotating belt 4-4 close to the plane 1-4 is greater than the friction force of the side of the rotating belt 4-4 away from the plane 1-4. The plane 1-4 of the energy-gathering tube 1 is pulled by the rotating belt 4-4, so that the energy-gathering tube 1 can be stably transported into the blasthole.

[0041] After the energy-gathering tube 1 is inserted into the blasthole, the clamping force between the clamping plate 4-1 and the plane 1-4 is canceled, and the rotating belt 4-4 is brought into contact with the inner wall of the blasthole;

[0042] At this time, the teeth 4-8 are rotated in the opposite direction. At this time, the friction between the outer wall of the energy-gathering tube 1 and the inner wall of the blasthole is greater than the friction between the side of the rotating belt 4-4 close to the plane 1-4, which can make the side of the rotating belt 4-4 close to the plane 1-4 fit the inner wall of the blasthole and rotate. The splint 4-1 is pulled out from the blasthole along the rotation direction of the rotating belt 4-4. At this time, the rotating belt 4-4 does not contact the energy-gathering tube 1, and can keep the distance between the two adjacent energy-gathering tubes 1 unchanged when the splint 4-1 is pulled out, thereby ensuring the accuracy of blasting.

[0043] like Figures 4 to 6 As shown, guide rails 4-13 are fixedly installed on both sides of the width direction of the first part 4-11, and blocks are fixedly installed on both ends of the guide rails 4-13. An arc groove 4-31 is provided on the inner surface of the positioning ring 4-3, and a sliding block 4-32 is slidably installed in the arc groove 4-31. A snap-fit ​​groove 4-33 is provided on the sliding block 4-32. The guide rail 4-13 passes through the snap-fit ​​groove 4-33, and the sliding block 4-32 can slide on the guide rail 4-13.

[0044] When the clamping plate 4-1 moves, the sliding block 4-32 slides on the guide rail 4-13, so that the first part 4-11 can be inserted into and withdrawn from the blasthole and remains stable. When the sliding block 4-32 moves to the two ends of the guide rail 4-13, it is blocked by the stopper to prevent the sliding block 4-32 from falling off the guide rail 4-13.

[0045] After the energy-gathering tube 1 is inserted into the blasthole, the orientation of the first scale 2-1 in the circumferential direction of the blasthole is adjusted. The first scale 2-1 drives the energy-gathering tube 1 to rotate, so that the plane 1-4 can drive the clamping plate 4-1 to rotate in the blasthole. The clamping plate 4-1 drives the sliding block 4-32 to slide in the arc groove 4-31. When the orientation of the V-shaped energy-gathering groove is adjusted, the clamping plate 4-1 can maintain a clamping state to prevent the distance between two adjacent energy-gathering tubes 1 from changing during rotation.

[0046] Then the scale 2 is pulled out from the energy-gathering tube 1. At this time, the splint 4-1 maintains the clamping effect on the energy-gathering tube 1 to ensure that the distance between two adjacent energy-gathering tubes 1 will not change when the scale 2 is pulled out, thereby achieving the effect of recovering the scale 2. Then the splint 4-1 is pulled out from the blasthole to complete the operation of inserting the energy-gathering tube 1 into the blasthole.

[0047] like Figure 4 As shown, a driving motor 4-15 is fixedly mounted on the third rotating wheel 4-7 which is farthest from the first part 4-11, a mounting bracket 4-16 is fixedly mounted on the outer wall of the driving motor 4-15, and the mounting bracket 4-16 is fixedly mounted on the inner surface of the second part 4-12. Two driving motors 4-15 are provided, and the two driving motors 4-15 are fixedly mounted on the two second parts 4-12.

[0048] Start the driving motor 4-15, so that the driving motor 4-15 drives the third rotating wheel 4-7 to rotate, and the third rotating wheel 4-7 drives the rotating belt 4-4 to rotate, so that when the rotating belt 4-4 drives the energy-gathering tube 1 to be inserted into the blasthole, the distance between the two adjacent energy-gathering tubes 1 will not change, and the rotating belt 4-4 moves on the inner wall of the blasthole to facilitate the extraction of the splint 4-1 from the blasthole.

[0049] like Figure 2 The bottom ends of the two positioning rings 4-3 shown are fixedly installed with a connecting rod 4-21, and the bottom end of the connecting rod 4-21 is fixedly installed with a sliding plate 4-22. The sliding plate 4-22 is sleeved on the sliding seat 4-2, and a two-way threaded sleeve 4-23 is provided between the bottom ends of the two sliding plates 4-22. Both ends of the two-way threaded sleeve 4-23 are rotatably installed with threaded rods 4-24, and the ends of the two threaded rods 4-24 away from the two-way threaded sleeve 4-23 are fixedly installed on the bottom ends of the two sliding plates 4-22 respectively.

[0050] After the energy-gathering tube 1 is assembled, the plane 1-4 of the first energy-gathering tube 1 is located within the range of the second part 4-12. At this time, the bidirectional threaded sleeve 4-23 is rotated to drive the threaded rods 4-24 on both sides to approach each other, so that the sliding plates 4-22 on both sides can drive the connecting rods 4-21 to approach each other, thereby achieving the effect of the second part 4-12 clamping the energy-gathering tube 1, and at the same time assembling the two positioning rings 4-3 into a complete circular ring.

[0051] like Figure 1 and Figure 3 As shown, handles 4-25 are fixedly mounted on both ends of the sliding seat 4-2, and the distance between the handles 4-25 is greater than the distance between the two driving motors 4-15.

[0052] During the process of aligning the positioning ring 4-3 with the blast hole, the handheld handle 4-25 controls the height of the sliding seat 4-2 on the limit rod 3-2, and corresponds to the height of the positioning ring 4-3 and the blast hole. When the end of the first part 4-11 is inserted into the blast hole, it is blocked by the blast hole, and the positioning ring 4-3 can drive the sliding plate 4-22 to move on the sliding seat 4-2, so that the positioning ring 4-3 can adapt to the hole in the horizontal direction, so that when the subsequent energy-gathering tube 1 is inserted into the blast hole, the inside of the blast hole can be detected in advance to prevent the friction of the inner wall of the blast hole from blocking the energy-gathering tube 1 during insertion, causing the distance between the two adjacent energy-gathering tubes 1 to change.

[0053] like Figure 2 As shown, a U-shaped movable plate 3-3 is provided on the top surface of the base plate 3-1, the bottom ends of the two limit rods 3-2 are fixedly mounted on both sides of the movable plate 3-3, and both ends of the movable plate 3-3 are fixedly mounted with limit plates 3-4. Both sides of the movable plate 3-3 are slidably mounted with limit sleeves 3-5, and the limit sleeves 3-5 are fixedly mounted on the top surface of the base plate 3-1.

[0054] 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 rotating wheel 4-5 and contacts the stopper. Then, the handle 4-25 is pulled, so that the limiting rod 3-2 drives the movable plate 3-3 to slide on the bottom plate 3-1. When the center part of the movable plate 3-3 contacts the limiting sleeve 3-5, the first part 4-11 is away from the blasthole, which facilitates the adjustment of the height of the first part 4-11.

[0055] After the height adjustment is completed, push the handle 4-25 to make the movable plate 3-3 slide on the bottom plate 3-1, and let the limit plate 3-4 contact the limit sleeve 3-5. At this time, the end of the first part 4-11 can be inserted into the blasthole, providing a guide for the subsequent first part 4-11 to be fully inserted into the blasthole.

[0056] When the energy-gathering tubes 1 are inserted, the distance between two adjacent energy-gathering tubes 1 can be kept unchanged. When the scale 2 is recovered, the distance between two adjacent energy-gathering tubes 1 can also be kept unchanged, thereby ensuring the blasting accuracy.

[0057] like Figure 7 and Figure 8As shown, in embodiment 2, a focusing tube with measurable spacing is accurately loaded into a blasthole using the above-mentioned precise loading device, and includes a plurality of focusing tubes 1 and a scale 2 for distributing the plurality of focusing tubes 1 according to a preset distance. The scale 2 is penetrated on the surface of the focusing tube 1, and two V-shaped focusing grooves are provided in the focusing tube 1. Planes 1-4 are provided on both sides of the surface of the focusing tube 1, and the two planes 1-4 correspond to the positions of the two V-shaped focusing grooves respectively.

[0058] A groove 1-1 is provided on the energy focusing tube 1, and 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 energy focusing grooves, and the radial direction of the first groove 1-2 is perpendicular to the radial direction of the top ends of the two V-shaped energy focusing grooves. There are two second grooves 1-3, and they are mirrored on the side of the two V-shaped energy focusing 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.

[0059] 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 energy-gathering tubes 1 by observing the scales on the scales 2. After multiple energy-gathering tubes 1 are installed on the second scales 2-2, the medicine roll is installed inside the energy-gathering tube 1, and the energy-gathering hole is installed at the bottom end of the energy-gathering tube 1;

[0060] After the energy-gathering hole is installed, the first scale 2-1 is passed through the first grooves 1-2 on the multiple energy-gathering tubes 1, and the first scale 2-1 is flush with the second scale 2-2. After the first scale 2-1 and the second scale 2-2 are plugged in, the scale 2 and the energy-gathering tube 1 are inserted into the blasthole together, so that the spacing between the multiple energy-gathering tubes 1 inserted into the blasthole can be controlled.

[0061] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of the present invention.
