Description

Technical Field

[0001] This utility model is a portable auxiliary charging device for mixed emulsion explosives, belonging to the field of deep hole blasting operations in open-pit mines. Background Technology

[0002] Currently, on-site mixed emulsion explosives are widely used in deep-hole blasting operations in open-pit mines. Compared to pre-compressed explosives, they are more economical and reduce labor costs. When using on-site mixed emulsion explosive trucks for loading, the loading coil must be inserted into the bottom of the borehole to begin injecting the mixed emulsion explosive. Once the explosive has filled to the preset loading height, the coil is then pulled out. However, because the coil outlet has already reached the bottom of the borehole and the mixed explosive has filled to the preset loading height, the resistance generated by the explosive and the frictional resistance between the coil and the borehole opening are significant, making coil retrieval difficult. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a portable auxiliary charging device for mixed emulsion explosives, thereby solving the problems mentioned in the background section. This invention simultaneously retracts the coil during the transport of the emulsion explosive, using a rotating roller to retract the coil, reducing friction between the coil and the borehole and improving charging efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a portable auxiliary charging device for mixed emulsion explosives, comprising a roller, an annular groove for limiting the position of a coil is machined at the center of the outer surface of the roller, first baffles are provided on both sides of the roller, the roller is rotatably connected to the first baffles via a connector, tubular columns are installed at both ends of the first baffles, and second baffles are provided on both sides of the roller along its width, arranged perpendicularly to the first baffles, the ends of the second baffles are connected and fixed to the corresponding tubular columns, the height of the first baffles is greater than the height of the second baffles, a horizontal tube is provided directly above the second baffle furthest from the roller, the two ends of the horizontal tube are respectively connected and fixed to two tubular columns, an inclined hollow tube is installed at the center of the outer surface of the horizontal tube, and a handle is installed at the end of the hollow tube away from the horizontal tube.

[0005] Furthermore, the connector includes an L-shaped plate, and an L-shaped plate is installed on the opposite sides of the two first baffles. A circular hole is opened on the vertical side of the L-shaped plate, and a through hole is opened on one side of the first baffle that is aligned with the circular hole. A semi-threaded screw is inserted into both ends of the roller and rotates through the roller. The end of the semi-threaded screw away from the roller passes through the channel formed by the through hole and the circular hole. Nuts are provided on both sides of the circular hole along the length of the semi-threaded screw, and the nuts are threadedly connected to the semi-threaded screw.

[0006] Furthermore, both ends of the roller are equipped with plug sleeves, and the end of the semi-threaded screw away from the nut is inserted into the plug sleeve.

[0007] Furthermore, an ear plate is provided between the round hole and the through hole. The upper end of the ear plate is connected and fixed to the horizontal part of the L-shaped plate. A through hole is provided on one side of the ear plate, which is aligned with the round hole. The semi-threaded screw passes through the through hole. There is a gap between the ear plate and the vertical part of the L-shaped plate. The ear plate and the vertical part of the L-shaped plate are located between the two nuts on the semi-threaded screw.

[0008] Furthermore, a reinforcing tube is provided directly above the first baffle, and both ends of the reinforcing tube are respectively connected and fixed to the corresponding tubular columns.

[0009] Furthermore, a lug is installed on the outer surface of the lower end of the tubular column, and a threaded hole is opened on the upper surface of the lug, with a long screw threaded into the threaded hole.

[0010] Furthermore, the roller has a cylindrical structure and is a component made of nylon material. The cross-section of the annular groove is U-shaped, and the depth of the annular groove is less than the radius of the coil.

[0011] The beneficial effects of this utility model are:

[0012] 1. When loading explosives, place the four corners of the support formed by the four tubing columns around the borehole. The blaster supports and limits the position using the handle formed by the hollow tube and the grip. The coil extends into the bottom of the borehole along the annular groove on the roller. The coil is recovered simultaneously during the transport of the emulsion explosive. The coil is retracted by rotating the roller, which reduces the friction between the coil and the borehole and improves the loading efficiency.

[0013] 2. The four tubing columns, two first baffles, and two second baffles together form a chair-shaped structure, which, with the obstruction of the first and second baffles, prevents gravel and rock fragments from falling into the borehole during the charging process.

[0014] 3. When the ground around the blast hole is uneven, tighten the long screws on the four lugs so that the lower end of the long screws contacts the uneven ground. Then, with the support of the four long screws, the four pipe columns, the two first baffles and the two second baffles can be placed stably in a chair-shaped structure.

[0015] 4. Insert one end of the semi-threaded screw into the plug sleeve, and then pass the other end of the semi-threaded screw through the channel formed by the through hole, the perforation, and the round hole. Use two nuts to restrict the relative position of the semi-threaded screw and the L-shaped plate to restrict the position of the roller. After separating the nuts and the semi-threaded screw, the roller can be replaced. When the nuts and the semi-threaded screw cannot be separated normally due to corrosion, use the space between the ear plate and the vertical part of the L-shaped plate to cut off the semi-threaded screw to facilitate the replacement of the semi-threaded screw.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a technical solution: a portable auxiliary charging device for mixed emulsion explosives, including a roller 1. The roller 1 has a cylindrical structure and is a component made of nylon material. The nylon material used for the roller 1 is anti-static, avoiding safety risks caused by static electricity generated by friction, and has strong wear resistance. An annular groove 2 for limiting the position of the coil is machined in the middle of the outer surface of the roller 1. The cross-section of the annular groove 2 is "U" shaped, and the depth of the annular groove 2 is less than the radius of the coil, so that the coil will not sway from side to side.

[0024] See Figures 1-4The roller 1 has first baffles 7 on both sides, and tubular posts 6 are installed at both ends of the first baffles 7. Second baffles 5 are arranged perpendicularly to the first baffles 7 on both sides of the roller 1 along its width. The ends of the second baffles 5 are connected and fixed to the corresponding tubular posts 6. The height of the first baffles 7 is greater than the height of the second baffles 5. A horizontal tube 13 is located directly above the second baffle 5 furthest from the roller 1. The two ends of the horizontal tube 13 are connected and fixed to the two tubular posts 6 respectively. A hollow tube 14 is installed at an angle in the middle of the outer surface of the horizontal tube 13. A handle 15 is installed at the end of the hollow tube 14 away from the horizontal tube 13. A reinforcing tube 12 is located directly above the first baffles 7, and the two ends of the reinforcing tube 12 are connected and fixed to the corresponding tubular posts 6 respectively. The four tubular posts 6, the two first baffles 7, and the two second baffles 5 together form a chair-shaped structure, preventing gravel and rock fragments from falling into the borehole during the charging process, thanks to the obstruction of the first baffles 7 and the second baffles 5. During the loading process, the four corners of the support formed by the four tubing columns 6 are placed around the borehole opening. The blaster supports and limits the movement using the handle formed by the hollow tube 14 and the grip 15. The coil extends into the bottom of the borehole along the annular groove 2 on the roller 1. The coil is simultaneously recovered during the transport of the emulsion explosive. The coil is retracted by rotating the roller 1, which reduces the friction between the coil and the borehole opening and improves the loading efficiency.

[0025] See Figures 1-4 Both first baffles 7 have L-shaped plates 11 installed on their back sides. The vertical side of the L-shaped plate 11 has a round hole 18. One side of the first baffle 7 has a through hole 17 aligned with the round hole 18. Both ends of the roller 1 are connected to a semi-threaded screw 10 that rotates with the roller 1. Both ends of the roller 1 are fitted with insertion sleeves 20. The end of the semi-threaded screw 10 furthest from the nut 9 is inserted into the insertion sleeve 20, and the end of the semi-threaded screw 10 furthest from the roller 1 passes through the channel formed by the through hole 17 and the round hole 18. Nuts 9 are provided on both sides of the hole 18 along the length of the semi-threaded screw 10. The nuts 9 are threadedly connected to the semi-threaded screw 10. An ear plate 8 is provided between the round hole 18 and the through hole 17. The upper end of the ear plate 8 is connected and fixed to the horizontal part of the L-shaped plate 11. A through hole 19 is provided on one side of the ear plate 8, which is aligned with the round hole 18. The semi-threaded screw 10 passes through the through hole 19. There is a gap between the ear plate 8 and the vertical part of the L-shaped plate 11. The ear plate 8 and the vertical part of the L-shaped plate 11 are located between the two nuts 9 on the semi-threaded screw 10. Insert one end of the semi-threaded screw 10 into the plug sleeve 20, and then let the other end of the semi-threaded screw 10 pass through the channel formed by the through hole 17, the through hole 19 and the round hole 18. Use two nuts 9 to restrict the relative position of the semi-threaded screw 10 and the L-shaped plate 11 to restrict the position of the roller 1. After separating the nuts 9 and the semi-threaded screw 10, the roller 1 can be replaced. When the nuts 9 and the semi-threaded screw 10 cannot be separated normally due to corrosion, use the space between the ear plate 8 and the vertical part of the L-shaped plate 11 to cut off the semi-threaded screw 10 to facilitate the replacement of the semi-threaded screw 10.

[0026] See Figures 1-3 The lower outer surface of the tubing column 6 is fitted with lugs 4, and the upper surface of the lugs 4 is provided with threaded holes 16, with long screws 3 connected to the internal threads of the threaded holes 16. When the ground around the blast hole is uneven, the long screws 3 on the four lugs 4 are tightened so that the lower ends of the long screws 3 contact the uneven ground. Thus, with the support of the four long screws 3, the four tubing columns 6, the two first baffles 7, and the two second baffles 5 can be stably placed in a chair-shaped structure.
