Technical Field

[0001] This utility model relates to the field of drug loading technology, and in particular to a long-distance drug loading device. Background Technology

[0002] Blasting engineering is a technique that uses the enormous energy released instantaneously by the explosion of explosives to destroy or deform the medium surrounding the explosives, thereby achieving certain engineering objectives. In mining engineering, drilling holes in ore or rock is called rock drilling, and loading explosives into the holes to break the ore or rock off their parent material is called blasting.

[0003] In actual blasting operations, the working faces and blasting sites of various tunnel excavation blasting, open-pit blasting and high-risk area blasting operations are rarely the flat working faces designed in the past. Traditional charging trolleys are difficult to operate, and manual loading poses huge safety hazards. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a long-distance loading device, which aims to improve the problems of traditional loading trolleys being difficult to operate on complex working surfaces and the huge safety hazards of manual loading.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a long-distance loading device, comprising a through tube, an insertion tube slidably connected to the inner wall of the through tube, two rivets symmetrically fixedly connected to one side of the insertion tube, a pull rope one fixedly connected to one side of one of the two rivets, and a pull rope two fixedly connected to one side of the other rivet, the outer walls of both the pull rope one and the pull rope two being slidably connected inside the through tube, a pull ring fixedly connected to one end of both the pull rope one and the pull rope two, a spherical head rotatably connected to the bottom of the through tube, a pulley symmetrically rotatably connected to the inner wall of the spherical head, an operating tube one fixedly connected to one side of the spherical head, a connecting block two fixedly connected to one side of both the operating tube one and the through tube, a rivet three fixedly connected to the top of the connecting block two, a connecting block one rotatably connected to the outer wall of the rivet three, a limiting structure fixedly connected to the other side of the operating tube one, and an extension structure slidably connected to the outer wall of the operating tube one.

[0006] By adopting the above technical solution, adjusting the extension structure to the appropriate length to adapt to the borehole height, connecting the first connecting block, adjusting the angle between the first operating tube and the through tube using the spherical head, fixing the angle using the limiting structure, loading the emulsion explosive into the through tube, aligning the opening of the through tube with the borehole opening, pulling the first pulling rope to radially push the explosive into the borehole and push the emulsion explosive into the designed position inside the borehole, pulling the second pulling rope to pull the through tube out of the borehole, and repeating the above steps until the emulsion explosive is loaded to the designed quantity, thus achieving safe loading of explosives over long distances.

[0007] Preferably, the limiting structure includes a connecting block three, one side of which is fixedly connected to the other side of the operating tube one.

[0008] Preferably, a rivet is fixedly connected to the top of the connecting block three, and a semi-circular disk is rotatably connected to the outer wall of the rivet one.

[0009] Preferably, ratchet teeth are uniformly fixedly connected to the inner wall of the semi-circular disk, and a limit block is engaged with one side of the ratchet teeth.

[0010] Preferably, a pulling block is fixedly connected to the top of the limiting block one, and a limiting spring is fixedly connected inside the limiting block one.

[0011] Preferably, one end of the limiting spring is fixedly connected to the outer wall of the through tube, and a limiting rod is fixedly connected to the outer wall of the through tube, the limiting rod being located inside the limiting block one.

[0013] Preferably, a spring clip is fixedly connected to the outer wall of the second operating tube, and a limit block two is fixedly connected to one side of the spring clip.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by adjusting the extension structure of appropriate length to adapt to the height of the borehole, and by connecting the first connecting block, the angle between the first operating tube and the through tube is adjusted using the spherical head, and the angle is fixed by the limiting structure. The emulsion explosive is loaded into the through tube, the opening of the through tube is aligned with the borehole opening, the first pulling rope is pulled, so that the inserting tube radially pushes the explosive into the borehole, and pushes the emulsion explosive into the designed position in the borehole. The second pulling rope is pulled, and the inserting tube is pulled out of the borehole. The above steps are repeated until the emulsion explosive is loaded to the designed quantity, thus realizing safe loading of explosives at a distance.

[0016] 2. In this utility model, by lifting the spring clip, the limiting block two is separated from the holes on the operating tube two and the operating tube one. The limiting block two is released from limiting the operating tube two and the operating tube one, and the operating tube two can slide freely to extend to a suitable length. When the spring clip is lowered, the spring clip drives the limiting block two to reset, pass through the hole of the operating tube two, and engage with the new hole on the operating tube one, thus completing the length extension fixation.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-6An embodiment of this utility model provides a long-distance loading device, comprising a through tube 1, an insertion tube 2 slidably connected to the inner wall of the through tube 1, rivets 11 symmetrically fixedly connected to one side of the insertion tube 2, a pull rope 8 fixedly connected to one side of one rivet 11, and a pull rope 9 fixedly connected to one side of the other rivet 11, the outer walls of pull ropes 8 and 9 slidably connected to the inside of the through tube 1, a pull ring 10 fixedly connected to one end of each pull rope 8 and 9, a spherical head 17 rotatably connected to the bottom of the through tube 1, a pulley 19 symmetrically rotatably connected to the inner wall of the spherical head 17, an operating tube 3 fixedly connected to one side of the spherical head 17, a connecting block 15 fixedly connected to one side of both the operating tube 3 and the through tube 1, a rivet 16 fixedly connected to the top of the connecting block 15, a connecting block 6 rotatably connected to the outer wall of the rivet 16, a limiting structure fixedly connected to the other side of the operating tube 3, and an extension structure slidably connected to the outer wall of the operating tube 3.

[0027] Specifically, by adjusting the extension structure to the appropriate length to adapt to the borehole height, opening the limiting structure, connecting block 16 is connected to rivet 3 16 and connecting block 2 15, adjusting the angle between operating tube 1 3 and through tube 1 using ball head 17, closing the limiting structure to fix the angle, facilitating remote operation, loading the emulsion explosive into through tube 1, aligning the opening of through tube 1 with the borehole opening, pulling rope 1 8 and pulling rope 2 9 pass through the inner wall of through tube 1, and through the pulley 19 in ball head 17, turn to enter the interior of operating tube 1 3 and pass through the interior of the extension structure, pulling rope 1 8 causes the insertion tube 2 to radially push the explosive into the borehole, and pushes the emulsion explosive into the designed position in the borehole, pulling rope 2 9 pulls the insertion tube 2 out of the borehole, and repeating the above steps until the emulsion explosive is loaded to the designed quantity, improving the problem that traditional loading trolleys are difficult to operate on complex working faces, and that manual loading poses a huge safety hazard.

[0028] Reference Figure 2 , Figure 4 The limiting structure includes a connecting block 3 18. One side of the connecting block 3 18 is fixedly connected to the other side of the operating tube 1 3. A rivet 1 7 is fixedly connected to the top of the connecting block 3 18. A semi-circular disk 5 is rotatably connected to the outer wall of the rivet 1 7. A ratchet 13 is evenly fixedly connected to the inner wall of the semi-circular disk 5. A limiting block 14 is engaged on one side of the ratchet 13. A pulling block 12 is fixedly connected to the top of the limiting block 14. A limiting spring 21 is fixedly connected inside the limiting block 14. One end of the limiting spring 21 is fixedly connected to the outer wall of the through tube 1. A limiting rod 20 is fixedly connected to the outer wall of the through tube 1. The limiting rod 20 is located inside the limiting block 14.

[0029] Specifically, by pulling the pull block 12 outward, the limiting spring 21 is stretched. Under the limitation of the limiting rod 20, the limiting block 14 moves outward and disengages from the ratchet 13. The semi-circular disk 5 can slide within a certain angle through the slot under the limitation of the limiting rod 20 to achieve angle adjustment. When the pull block 12 is lowered, the limiting spring 21 contracts, pulling the limiting block 14 downward to slide downward under the limitation of the limiting rod 20. The limiting block 14 engages the new ratchet 13 to fix the new angle.

[0030] Reference Figure 5 The extended structure includes an operating tube 2 4, the inner wall of which is slidably connected to the outer wall of the operating tube 1 3, and a spring clip 22 is fixedly connected to the outer wall of the operating tube 2 4. A limit block 23 is fixedly connected to one side of the spring clip 22.

[0031] Specifically, by lifting the spring clip 22, the limiting block 23 is moved away from the holes on the operating tube 2 4 and the operating tube 1 3. The limiting block 23 is released from limiting the operating tube 2 4 and the operating tube 1 3, allowing the operating tube 2 4 to slide freely and extend to a suitable length. When the spring clip 22 is lowered, the spring clip 22 drives the limiting block 23 to reset, pass through the hole in the operating tube 2 4, and engage with the new hole on the operating tube 1 3, thus completing the length extension fixation.

[0032] Working principle: In use, by lifting the spring clip 22, the limiting block 23 disengages from the limiting of the operating tube 24 and the operating tube 3, allowing the operating tube 24 to slide freely and extend to a suitable length. Lowering the spring clip 22 completes the extension length fixation, adapting to the borehole height. Pulling the pulling block 12 outward causes the limiting block 14 to move outward, disengaging from the ratchet 13. The semi-circular disc 5 can slide within a certain angle through the slot under the limiting rod 20. Through the connection of the connecting block 16, the ball head 1... 7. Adjust the angle between the operating tube 1-3 and the through tube 1, lower the pull block 12, and engage the new ratchet 13 with the limiting block 14 to fix the angle for easy remote operation. Load the emulsion explosive into the through tube 1, align the opening of the through tube 1 with the borehole opening, pull the pull rope 1-8 to radially push the explosive into the borehole through the insertion tube 2, and push the emulsion explosive into the designed position in the borehole. Pull the pull rope 2-9 to pull the insertion tube 2 out of the borehole. Repeat the above steps until the emulsion explosive is loaded to the designed quantity.
