Description

Technical Field

[0001] The utility model relates to the technical field of mine anti-bumping and pressure-relieving engineering, in particular to a charging auxiliary device for a head-on blasting hole. Background Art

[0002] When the anchor and digger is excavating the tunnel and loading the blasting hole at the head, there is no standing platform at the cutting drum of the anchor and digger, so people cannot stand. When loading, the people are far away from the hole mouth, and the explosives in the tube are soft, so they cannot be connected and loaded into the hole normally. This may cause the explosives in the tube to get stuck in the hole and remain inside, so they cannot be loaded into the bottom of the hole, affecting the pressure relief range.

[0003] For example, patent application number CN201010126596.1 discloses an auxiliary charging device for an ammonium oil fuel explosive charging vehicle. The invention has the advantages of short charging positioning time, a large number of blastholes that can be filled at one time, high efficiency and low blasting cost. The ammonium oil fuel explosive charging vehicle can load 4-5 blastholes at each time instead of one blasthole at the original time when loading, which greatly shortens the positioning time of the charging vehicle when loading and improves labor efficiency. When in use, the personnel are far away from the hole mouth when loading, and the tube explosive is soft, so the tube explosive cannot be connected and loaded into the hole normally, which may cause the tube explosive to get stuck in the hole and remain inside, so it cannot be loaded into the bottom of the hole, affecting the pressure relief range.

[0004] For example, patent application number CN201911135585.7, this invention relates to a step blasting air interval charging auxiliary device. The spacers are lowered in sequence by the operating rod. When the spacers are placed in the designed position, the operating rod is slightly pressed downward, and the lower end of the hook of the operating rod is disengaged from the groove, and separated from the spacer under the action of the spring, and the operating rod can be lifted. The present invention can simultaneously realize axial and radial uncoupled charging. When in use, when personnel are charging, they are far away from the orifice, and the tube explosives are soft, so they cannot be connected and loaded into the hole normally. It is possible that the tube explosives are stuck in the hole and remain inside, so they cannot be loaded into the bottom of the hole, affecting the pressure relief range. Utility Model Content

[0026] The moving mechanism 2 includes a circular plate 201, and the circular plate 201 is adapted to the inner wall of the outer cylinder 1. A connecting plate 202 is arranged on one side of the circular plate 201, and the connecting plate 202 contacts the inner wall of the outer cylinder 1. A moving plate 203 is arranged on the end of the connecting plate 202 away from the circular plate 201. A motor 204 is fixedly arranged on the front side of the connecting plate 202, and a rotating rod 205 is arranged on the output shaft end of the motor 204. A pushing plate 206 is fixedly arranged on one side of the rotating rod 205, and the pushing plate 206 contacts the moving plate 203. A fixed rod 207 is arranged on the front side of the motor 204, and a cross bar 208 is arranged on one side of the moving plate 203. The cross bar 208 penetrates the fixed rod 207 and is movably connected with the fixed rod 207.

[0027] A connecting spring 209 is disposed on the outer side of the cross bar 208 , and the connecting spring 209 is located on one side of the fixing bar 207 .

[0028] A protrusion 210 is provided on the top of the circular plate 201, and a slide groove 213 is provided on the inner wall of the top end of the outer cylinder 1. The slide groove 213 is located on one side of the protrusion 210. A ball 214 is provided on one side of the connecting plate 202. The number of the ball 214 is multiple. A telescopic rod 215 is provided on one side of the connecting plate 202. The connecting plate 202 is fixedly connected to the moving plate 203 through the telescopic rod 215.

[0029] See also Figure 1-3 5. The slide groove 213 is adapted to the protrusion 210. A threaded rod 211 is arranged inside the slide groove 213. The threaded rod 211 penetrates the protrusion 210 and is threadedly connected with the protrusion 210. A cross rod 212 is arranged inside the slide groove 213. The cross section of the cross rod 212 is a cross shape. One end of the cross rod 212 extends to the inside of the threaded rod 211 and contacts the threaded rod 211. One end of the cross rod 212 extends to the inside of the threaded rod 211 and contacts the threaded rod 211, so that the circular plate 201, the moving plate 203 and the connecting plate 202 connected by the threaded rod 211 move at the same time, and the distance between them and the outer cylinder 1 can be expanded, so that the moving plate 203 is no longer located inside the outer cylinder 1, and there can be a certain distance between them and the outer cylinder 1, which is convenient for placing the material inside the outer cylinder 1.

[0030] During operation, one end of the outer cylinder 1 is inserted into the designated position. Since one end of the cross rod 212 extends to the inside of the threaded rod 211 and contacts the threaded rod 211, the threaded rod 211 is moved linearly, and the circular plate 201, the moving plate 203 and the connecting plate 202 connected to the threaded rod 211 are moved at the same time, and the distance between the outer cylinder 1 and the moving plate 203 is enlarged, so that the moving plate 203 is no longer located inside the outer cylinder 1, and there is a certain distance between the moving plate 203 and the outer cylinder 1, which is convenient for placing the material inside the outer cylinder 1 and aligning the material through the outer cylinder 1. After placing, the circular plate 201, the moving plate 203 and the connecting plate 202 connected by the threaded rod 211 are moved again, so that the circular plate 201, the moving plate 203 and the connecting plate 202 enter the outer cylinder 1, and drive the movement of the protrusion 210, so that the protrusion 210 moves linearly. Since the slide groove 213 is adapted to the protrusion 210, the protrusion 210 enters the slide groove 213, which pushes the material in the outer cylinder 1 to move. The motor 204 is used. Since the output shaft of the motor 204 The end is connected to the rotating rod 205 by transmission, and the rotating rod 205 is driven to rotate by the motor 204, and the pushing plate 206 fixedly connected to the rotating rod 205 rotates at the same time. When the pushing plate 206 rotates, it can be separated from or merged with the moving plate 203. When merging, it can push the moving plate 203 and the cross bar 208 to move. Since the cross bar 208 is movably connected to the fixed rod 207, the movement of the cross bar 208 is guaranteed, and the connecting spring 209 is deformed, and the movement of the moving plate 203 can push The material at the movable moving plate 203 moves. When separated, the movable plate 203 is automatically reset by connecting the spring 209, and then the threaded rod 211 is rotated. Since the threaded rod 211 is threadedly connected with the protrusion 210, the protrusion 210 moves, and the movable plate 203 and the circular plate 201 move at the same time, allowing the circular plate 201 to enter the outer cylinder 1 and move, pushing all the materials inside to fall and reduce residues, and the ball 214 at the circular plate 201 contacts the inner wall of the outer cylinder 1, making it easy to move.
