Description

Technical Field

[0001] This utility model relates to the field of air spacer technology, and in particular to an air spacer for blasting that can improve the efficiency of explosive loading. Background Technology

[0002] Air spacers for blasting are energy-saving devices used in open-pit blasting. They separate explosive charges into layers, solving the problem of uneven blast energy distribution, improving charging efficiency, saving explosives, and ensuring effectiveness. They achieve air-spaced charging by inflating air bags to clamp the blast hole or by inflating air bladders for fixation, thus optimizing the distribution of blast energy.

[0003] Existing air separators have problems such as easy misalignment during docking, the need for continuous manual support to prevent detachment, and poor stability during loading. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies and provide an air spacer for blasting that can improve the efficiency of explosive loading.

[0005] Therefore, this utility model provides an air spacer for blasting that can improve the efficiency of explosive loading. It includes an explosive tube with four first movable slots inside. A spring is fixedly connected to the inner wall of each first movable slot. A locking pin is fixedly connected to one end of each spring. A movable block is fixedly connected to the upper surface of the locking pin. A movable pin is fixedly connected to the upper surface of the movable block. A rotating ring is rotatably installed inside the explosive tube. Four inclined slots are formed on the upper surface of the rotating ring. The movable pin is located inside the inclined slots. A lower explosive tube is positioned above the explosive tube. Four locking slots are formed on the outer surface of the lower explosive tube. The locking pin is located inside the locking slots.

[0006] Preferably, a first limiting groove is provided at the inner top of the first moving groove, and the moving block is located inside the first limiting groove.

[0007] Preferably, a first rotating groove is provided at the inner top of the first limiting groove, and the rotating ring is located inside the first rotating groove.

[0008] Preferably, the outer surface of the explosive tube is provided with a second rotating groove, and a lever is fixedly connected to the outer surface of the rotating ring, the lever being located inside the second rotating groove.

[0009] Preferably, a first baffle is fixedly connected to the inner surface of the explosive tube, and the first baffle is spiral in shape.

[0010] Preferably, the inner surface of the explosive tube is fixedly connected with four limiting pins, and the outer surface of the explosive tube is provided with four second limiting grooves, with the limiting pins located inside the second limiting grooves.

[0011] Preferably, the lower surface of the explosive tube is provided with a threaded groove, and an air tube is threadedly connected to the inner surface of the threaded groove.

[0012] Preferably, a second baffle is fixedly connected to the inner surface of the explosive tube, and the second baffle is located between the air tube and the first baffle.

[0013] This utility model provides an air spacer for blasting that can improve the efficiency of explosive loading, and has the following beneficial effects:

[0014] Compared with existing technologies, this blasting air spacer, which improves charging efficiency, utilizes a rotating ring, inclined groove, movable pin, movable block, locking pin, spring, limiting pin, and second limiting groove. When explosives need to be filled, the limiting pin of the explosive tube is aligned with the second limiting groove of the discharge tube, allowing the explosive tube to move closer to the discharge tube. Simultaneously, the lever is turned counterclockwise, causing the rotating ring to rotate counterclockwise, which in turn moves the movable pin in the inclined groove, causing adjacent movable pins to move away from each other, and subsequently causing adjacent movable blocks and locking pins to move away from each other. The spring contracts, at which point the locking pin is fully retracted into the first movable groove. The explosive tube continues to move closer to the discharge tube until the explosive is fully loaded. When the tube can no longer move, the lever is released, the spring rebounds and the locking pin resets, then the locking pin enters the slot. At this point, the explosive tube is fixed to the outer wall of the charging tube. Charging can then be done without the need for staff to hold the explosive tube, effectively saving manpower and improving charging efficiency. Compared with existing air spacers, which have problems such as easy misalignment during docking, need for continuous manual support to prevent detachment, and poor stability during charging, this blasting air spacer, which can improve charging efficiency, has high docking accuracy, convenient and stable connection and fixation, can complete charging without manual support, and greatly improves the stability and efficiency of the charging process.

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Depend on Figures 1-9As shown, this utility model provides an air gap for blasting that can improve the efficiency of explosive loading. It includes an explosive tube 1, with four first movable grooves 2 inside the explosive tube 1. Springs 3 are fixedly connected to the inner walls of the first movable grooves 2, and a locking pin 4 is fixedly connected to one end of each spring 3. A movable block 5 is fixedly connected to the upper surface of the locking pin 4, and a movable pin 6 is fixedly connected to the upper surface of the movable block 5. A rotating ring 7 is rotatably installed inside the explosive tube 1, with four inclined grooves 8 on its upper surface. The movable pin 6 is located inside the inclined grooves 8. A discharge pipe 9 is located above the explosive tube 1, serving as a discharge pipe below the discharge device. Four locking grooves 10 are formed on the outer surface of the discharge pipe 9. When explosives need to be filled, the limiting pin 16 of the explosive tube 1 is aligned with the discharge pipe. The second limiting groove 20 of 9 allows the explosive tube 1 to move closer to the discharge tube 9. At the same time, the counterclockwise movement of the dial block 13 causes the rotating ring 7 to rotate counterclockwise, which in turn causes the moving pin 6 to move in the inclined groove 8, thereby causing the adjacent moving pins 6 to move away from each other, and then causing the adjacent moving blocks 5 and the locking pin 4 to move away from each other. The spring 3 contracts, and at this time the locking pin 4 is completely retracted into the first moving groove 2. The explosive tube 1 continues to move closer to the discharge tube 9 until the explosive tube 1 can no longer move. At this time, the dial block 13 is released, the spring 3 rebounds and causes the locking pin 4 to reset, and then the locking pin 4 enters the locking groove 10. At this time, the explosive tube 1 is fixed to the outer wall of the discharge tube 9. At this time, the explosive tube 1 can be discharged without the staff holding the explosive tube 1, which effectively saves manpower and improves the loading efficiency. The locking pin 4 is located inside the locking groove 10.

[0027] Depend on Figures 1-9As shown, this utility model provides an air spacer for blasting that can improve the efficiency of explosive loading. A first limiting groove 11 is provided at the top inner side of the first moving groove 2. The moving block 5 is located inside the first limiting groove 11, which restricts the movement of the moving block 5 and prevents it from shifting during movement. A first rotating groove 12 is provided at the top inner side of the first limiting groove 11, and a rotating ring 7 is located inside the first rotating groove 12, which provides rotation space for the rotating ring 7. A second rotating groove 14 is provided on the outer surface of the explosive tube 1. A lever 13 is fixedly connected to the outer surface of the rotating ring 7, and the lever 13 is located inside the second rotating groove 14, which provides rotation space for the lever 13. Moving the lever 13 will cause the rotating ring 7 to rotate. A first baffle 15 is fixedly connected to the inner surface of the explosive tube 1. The first baffle 15 is in the shape of... The explosive tube 1 is spiral-shaped. The first baffle 15 enhances the strength of the explosive tube 1. Four limiting pins 16 are fixedly connected to the inner surface of the explosive tube 1. Four second limiting grooves 20 are opened on the outer surface of the discharge tube 9. The limiting pins 16 are located inside the second limiting grooves 20. The limiting pins 16 and the second limiting grooves 20 cooperate to allow the explosive tube 1 to better connect with the discharge tube 9, facilitating the loading of explosives. The lower surface of the explosive tube 1 has a threaded groove 18. An air tube 17 is threadedly connected to the inner surface of the threaded groove 18. An air bag can be placed in the air tube 17. The air bag, through its spacing effect, makes the explosive energy more evenly distributed in the target blasting section, reducing the "local excessive fragmentation" of the borehole wall caused by energy concentration. The threaded connection also makes the installation of the explosive tube 1 and the air tube 17 more convenient. A second baffle 19 is fixedly connected to the inner surface of the explosive tube 1. The second baffle 19 is located in the air tube 17. Between the first baffle 15 and the second baffle 19, the explosive tube 1 and the air tube 17 are separated to prevent the explosive from coming into direct contact with the air bag.
