Description

Technical Field

[0001] The utility model relates to the technical field of blasting charges, and in particular provides a quick charging device for deep hole blasting. Background Art

[0002] Deephole blasting is becoming increasingly common, but deep charging of explosives into the blastholes requires significant resistance and large single-charge quantities. Most blastholes are placed obliquely upward, making charging difficult and labor-intensive. Existing technology typically uses a charging tube to deliver explosives into the blastholes, but this process presents significant resistance and is difficult to install manually. Furthermore, existing charging tube structures are laborious to install and can be loose. To ensure safe charging during deephole blasting, facilitate deephole charging, and reduce the workload of underground charging, further improvements to existing deephole blasting equipment are needed.

[0020] Combine Figures 1 to 4 As shown, a specific implementation of a quick charging device for deep hole blasting provided by the utility model is described.

[0021] A quick-charging device for deep-hole blasting, suitable for various deep-hole blasting applications, such as underground coal mines, tunnels, and rock masses, comprises a detachable blasting rod 4, an automatic pre-tensioning sleeve 2, and a tensioning mechanism 3. The blasting rod is used to hold the explosive. The automatic pre-tensioning sleeve 2 flexibly clamps the detachable blasting rod under the pull of a connecting rope. The tensioning mechanism automatically or manually pulls the connecting rope, making the charging process more time-efficient and labor-saving. A screw joint 1 is provided at the end of the detachable blasting rod 4, which is equipped with a buckle. Several detachable blasting rods are sequentially installed using the screw joints. The number of detachable blasting rods 4 is adjusted based on the depth of the blasthole. The automatic pre-tensioning sleeve 2 is mounted on the blasting rod. The segments 8 of the automatic pre-tensioning sleeve are hingedly connected, allowing the detachable blasting rod to be tightened or loosened by the expansion and contraction of the segments 8. The tensioning mechanism 3 can be fixedly mounted on the plane of the blasthole, specifically near the blasthole. The number of tensioning mechanisms 3 can be adjusted as needed. Increasing the number of tensioning mechanisms 3 increases the force applied to the blasting rod, making it easier to guide it into the blasthole. One end of the connecting rope is connected to the pipe segment of the automatic pre-tightening pipe sleeve 2, and the other end is connected to the tensioning mechanism 3, through which the detachable gun rod 4 can be pulled to move into the gun hole.

[0022] The tensioning mechanism 3 is a manual hoist or a winch. The manual hoist guides the detachable gun rod into the blast hole by manually pulling the connecting rope. The winch 9 can automatically pull the rope and then automatically guide the detachable gun rod into the blast hole.

[0023] The detachable baton 4 is made of PVC tubing, with each section measuring approximately 2 meters. This not only ensures the safety of the explosives but also reduces costs. The detachable baton 4 is a hollow tube containing the explosive 5. A partition or fixing mechanism can be incorporated into the tube to position the explosive 5 at a specific location within the tube. The buckles are thread-type buckles, with the gaps increasing from thin to thick. Once the two sections are locked, they can be rotated to tighten and prevent them from falling out.

[0024] Several segments 8 are provided, typically 2-3. The number of tensioning mechanisms 3 installed equals the number of segments. The segment length is 5-10 cm, and the inner diameter of the automatic preload sleeve 2 is equal to or greater than the outer diameter of the detachable blasting rod. When two segments 8 are used, the left and right halves are connected by two rotatable anchor points. When the manual hoist is not under load, the segment is relaxed. When the blasting rod is under load, the connecting rope between the segment 8 and the manual hoist is stressed. Depending on the load, the segment 8 grips the blasting rod and moves into the blasting hole 6.

[0025] The connecting rope can be an iron chain, and the manual hoist or winch is fixed on the surrounding rock 7 through a hook. The manual hoist is fixed around the borehole through a hook to realize manual control, and the winch is fixed through a hook.

[0026] The connecting rope can also be made of materials such as iron chain, steel wire rope or nylon rope. The manual hoist or winch is fixed on the anchor tray through a high-strength magnet. It is mainly used in places where it is inconvenient to install hooks. It can be directly fixed on the anchor, making it convenient to use in coal mines.

[0027] The structure of the tensioning mechanism 3 can also include a manual hoist and a winch. The connecting rope is fixedly connected to the pipe segment and pulls the pipe segment to rotate. The connecting rope passes through the manual hoist and is connected to the winch. The winches connected to the connecting ropes operate synchronously. By pulling the connecting ropes synchronously, the detachable gun stick can be pulled into the drill hole.

[0028] The device has a simple structure, is easy to install, and has a low production cost. Using the device for drilling and charging can ensure the safety of charging, especially for upward-inclined blastholes, and can complete the charging in a time-saving and labor-saving manner.

[0029] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
