Description
Technical Field
[0001] The utility model belongs to the technical field of blasting hole filling, and particularly relates to a blasting hole filling and fixing device. Background Technique
[0002] Blasting hole filling refers to injecting filling materials (such as cement, sand or other stabilizers) into the blast holes during blasting operations such as in mines or building demolitions to improve the efficiency and safety of blasting. The main functions of the filling materials are to enhance the blasting effect, control the release of explosion energy, and prevent the collapse or soil subsidence inside the blast holes. Effective filling can ensure the concentrated release of energy during blasting, thereby improving the recovery rate of ore mining and the accuracy of blasting. Existing filling methods often have difficulty in achieving uniform distribution of materials inside the blast holes, resulting in poor blasting effects. The conventional countermeasure is to use the manual step-by-step filling method to fill the inside of the blast holes, so as to reduce the gaps between the fillers, increase the tightness between the fillers, and thus improve the blasting efficiency. However, the disadvantage of this method is that manual filling takes a lot of time, and the insecure sealing at the top of the blast hole will cause the fillers to splash out of the blast hole, posing a safety hazard. Therefore, a new structure is proposed to solve the above problems. Content of the Utility Model

In actual use, the two sides of the top of the vibration frame are held and the vibration frame is vibrated up and down, so that the butt joint tube at the bottom of the vibration frame stretches or squeezes the spring up and down inside the butt joint groove, thereby feeding back to the vibration frame through the elastic force of the spring to increase the vibration frequency of the vibration frame, and then small pieces of gravel in the gravel fall down along the sieve holes to the top of the bottom plate (the diameter length of small pieces of gravel is greater than 0.5 cm and less than 1 cm, and the diameter length of large pieces of gravel is greater than 1 cm). After the top of the bottom plate is filled with small pieces of gravel, the small pieces of gravel slide around the bottom plate.

[0031] The wire tube 400 is made of stainless steel, and the bottom of the wire tube 400 passes through the top of the top cover 300 and the bottom of the bottom plate 230 respectively. The wire tube 400 is connected and fixed to the center of the vibration frame 100, and the wire tube 400 is connected and fixed to the center of the bottom plate 230. The diameter of the sieve hole 110 is 1 cm.
[0032] The wire tube 400 passes through the center of the butt joint tube 120 and the fixed tube 220 respectively, the top of the butt joint tube 120 is welded and fixed to the outer bottom of the vibration frame 100, the top of the butt joint tube 120 is connected with the outer bottom of the vibration frame 100, the bottom of the fixed tube 220 is welded and fixed to the center of the top of the vibration frame 100, and the bottom of the fixed tube 220 is connected with the top of the vibration frame 100.
[0033] The wall thickness of the butt joint pipe 120 matches the width of the butt joint groove 221, the radius length of the butt joint pipe 120 matches the radius length of the fixing tube 220, and the bottom of the butt joint pipe 120 is glued and fixed to the top of a plurality of groups of springs 222. In actual use, the top two sides of the vibration frame 100 are held and the vibration frame 100 is vibrated up and down, so that the butt joint pipe 120 at the bottom of the vibration frame 100 stretches or squeezes the spring 222 up and down inside the butt joint groove 221, so that the elastic force of the spring 222 is fed back to the vibration frame 100 to increase the vibration frequency of the vibration frame 100, thereby causing the small pieces of gravel to be broken. The stones fall down along the sieve holes 110 to the top of the bottom plate 230 (the diameter of small stones is greater than 0.5 cm and less than 1 cm, and the diameter of large stones is greater than 1 cm). After the top of the bottom plate 230 is filled with small stones, the small stones slide around the bottom plate 230. At this time, the net 210 catches the small stones and gathers them on the top of the bottom plate 230. The large stones are blocked by the sieve holes 110 and gradually gathered inside the vibration frame 100, so that the classification of the stones can be completed quickly, the density of the stone filling is increased, and the residence time of the shock wave in the blasthole is increased, thereby improving the explosion effect.
[0034] The side of the side nail 330 away from the protruding opening is a wedge-shaped structure, the top of the side nail 330 is welded and fixed to the bottom of the push-pull plate 320, the top of the push-pull plate 320 protrudes above the push-pull cavity, and the side nail 330 is made of stainless steel. In actual use, the screw hole of the top cover 300 is first passed through the lead wire and sleeved on the outside of the wire tube 400, and then the two sets of rotating handles 310 are held to rotate the top cover 300 forward to move the top cover 300 downward along the wire tube 400. When the bottom of the squeezing plate 340 at the bottom of the outer side of the top cover 300 contacts the top of the large rubble pile, the top cover 300 continues to rotate downward, and the squeezing plate 340 presses down the large rubble pile to drive the docking tube 120 to squeeze several sets of springs 222 downward, thereby vibrating The bottom of the frame 100 squeezes the small rubble pile downward to increase the density of the small rubble pile. After the squeezing is completed, the four groups of push-pull plates 320 are knocked in the direction away from the center of the circle with tools, so that the four groups of side nails 330 are nailed into the side walls of the blasthole, thereby ensuring the stability of the blasthole seal. The final effect is to increase the density of the large and small rubble piles through squeezing, thereby increasing the sealing inside the blasthole, prolonging the residence time of the explosion shock wave inside the blasthole, thereby improving the explosion effect. The top cover 300 is nailed into the inner wall of the blasthole through the four groups of side nails 330. When the shock wave impacts upward, the four groups of side nails 330 can stabilize the top cover 300 on the top of the blasthole to prevent the rubble from splashing out and causing safety hazards.
[0035] Example 1: Please refer to Figures 1 to 6In actual use, two workers are required to cooperate in the operation. First, the ground nails 231 are nailed into the ground, and the top cover 300 is rotated in the opposite direction by holding the two sets of rotating handles 310 to remove the top cover 300 from above the wire tube 400. Then, one worker fills the vibration frame 100 with gravel, and the other worker holds both sides of the top of the vibration frame 100 with both hands and vibrates it up and down, so that the docking tube 120 at the bottom of the vibration frame 100 stretches or squeezes the spring 222 up and down in the docking groove 221, so that the elastic force of the spring 222 is fed back to the vibration frame 100 to increase the vibration frequency of the vibration frame 100, thereby causing the gravel to be crushed. Small pieces of gravel in the stone fall down along the sieve holes 110 to the top of the bottom plate 230 (the diameter of small pieces of gravel is greater than 0.5 cm and less than 1 cm, and the diameter of large pieces of gravel is greater than 1 cm). After the top of the bottom plate 230 is filled with small pieces of gravel, the small pieces of gravel slide around the bottom plate 230. At this time, the net 210 catches the small pieces of gravel and gathers them on the top of the bottom plate 230. The large pieces of gravel are blocked by the sieve holes 110 and gradually gathered inside the vibration frame 100, so that the classification of gravel can be completed quickly, the density of gravel filling is increased, and the residence time of the shock wave in the blasthole is increased, thereby improving the explosion effect.
[0036] Example 2: Please refer to Figures 1 to 3 After the filling and screening are completed, a worker temporarily lifts the fixing device above the blasthole, and then another worker pulls out the lead wire and passes it through the wire tube 400 from bottom to top, so that the upper end of the lead wire passes through the top of the wire tube 400, and then slowly lowers the fixing device into the blasthole. Due to the restraint of the inner wall of the blasthole, the height of the small pieces of gravel will increase, thereby reducing the density of the small pieces of gravel pile, and then four groups of ground nails 231 are inserted into the explosive gunpowder. After the placement is completed, pick up the top cover 300, first pass the lead wire through the screw hole of the top cover 300 and sleeve it on the outside of the wire tube 400, and then hold the two groups of rotating handles 310 to rotate the top cover 300 in the forward direction, so that the top cover 300 moves downward along the wire tube 400;
[0037] When the bottom of the extrusion plate 340 at the outer bottom of the top cover 300 contacts the top of the large gravel pile, continue to rotate the top cover 300 downward. The extrusion plate 340 presses down on the large gravel pile, driving the docking pipe 120 to downwardly extrude a number of groups of springs 222, thereby pressing down on the small gravel pile through the bottom of the vibration frame 100, increasing the density of the small gravel pile. After the extrusion is completed, use tools to strike the four groups of push-pull plates 320 in a direction away from the center of the circle, thereby driving the four groups of side nails 330 into the inner wall of the blast hole side wall, so as to ensure the stability of the blast hole sealing part. The final effect is to increase the density of the large and small gravel piles through extrusion, thereby increasing the sealing inside the blast hole, extending the residence time of the explosion shock wave inside the blast hole, and thus improving the explosion effect. The top cover 300 is driven into the inner wall of the blast hole by the four groups of side nails 330. When the shock wave impacts upward, the four groups of side nails 330 can stabilize the top cover 300 at the top of the blast hole, preventing the splashing of gravel and causing potential safety hazards.
[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
