Description

Technical Field

[0001] This utility model belongs to the technical field of blasting auxiliary devices, and in particular relates to a deep-hole blasting charging device. Background Technology

[0002] Deep hole blasting is a common blasting technique in mining, construction engineering and other fields. Deep hole blasting usually uses a filling device to fill explosives into deep holes at intervals. For example, a deep hole blasting filling device disclosed in patent application number CN202023135732.1 includes a conveying rod, a line-laying rod and an explosive line. The other end of the connecting rod is fixedly connected to a second sliding plate. The upper and lower ends of the second sliding plate are both fixedly connected to second sliders. A spring is fixedly connected to the inside of the right end face of the conveying rod. Nuts are detachably connected to the outside of the other end of the screw.

[0003] The existing deep-hole blasting charging device lacks an effective detonating structure, which makes the blasting force easily dispersed. At the same time, the poor alignment accuracy between adjacent devices during the intermittent charging process further exacerbates the dispersion of blasting force. In addition, the emulsion explosive is prone to displacement in the charging device, reducing blasting efficiency. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a deep-hole blasting charging device that effectively reduces the dispersion of blasting force and improves blasting efficiency.

[0005] In view of this, the present invention provides a deep-hole blasting charging device, comprising:

[0006] A filling tube, wherein a filling space is formed inside the filling tube;

[0007] The drug delivery tube also includes:

[0008] The tube has two halves, which can be joined together to form a filling tube, and the joint between the two halves forms a detonation groove.

[0009] A positioning protrusion is provided in the inner wall of the semi-tube to center and fix the emulsion explosive filled in the filling space.

[0010] The connecting part includes an extension groove and an extension tube respectively arranged at both ends of the half-tube body;

[0011] The inner wall of the extension groove is provided with an alignment slot, and the outer wall of the extension tube is provided with an alignment strip. The alignment slot can cooperate with the alignment strip to align the detonating grooves on adjacent charge tubes.

[0012] In this technical solution, the charging tube is composed of two half-tubes spliced ​​together, and the joint between the two half-tubes forms a detonating groove, which concentrates the blasting force and reduces the dispersion of blasting force. At the same time, when multiple charging tubes are arranged at intervals in the deep hole, the extension groove and extension tube cooperate with each other to align and join adjacent charging tubes, thereby aligning the detonating grooves on adjacent charging tubes, further concentrating the blasting force and reducing the dispersion of blasting force. Meanwhile, when the emulsion explosive is injected into the filling space, the positioning protrusion can ensure that the emulsion explosive is centered and fixed in the filling space, thereby improving the uniformity of blasting.

[0013] Furthermore, the above technical solution also includes:

[0014] The splicing groove has two sections, and the two splicing grooves are distributed on the splicing surface of the two half-tubes;

[0015] The two splicing slots are equipped with locking blocks and slots respectively. The two splicing slots can be spliced ​​together and fixed by the cooperation of the locking blocks and slots.

[0016] Furthermore, the above technical solution also includes:

[0017] A positioning structure, comprising positioning protrusions and limiting blocks respectively arranged on two semi-tube bodies;

[0018] The positioning protrusion can cooperate with the limiting block to align the two half-tubes when they are joined together.

[0019] Furthermore, the above technical solution also includes:

[0020] Heat shrink tubing, wherein the heat shrink tubing is disposed at the end of the filling space, and both ends of the heat shrink tubing can be heat-sealed to form a closed bag;

[0021] The sealed bag formed by heat-shrink tubing is filled with a buffer medium.

[0022] In the above technical solution, the buffer medium further fills 85%-100% of the space of the closed bag formed by heat shrink tubing heat sealing.

[0023] The beneficial effects of this utility model are:

[0024] 1. The explosive charging tube is made up of two half-tubes joined together, which can form a detonating groove on the charging tube to reduce the dispersion of explosive force. At the same time, by using the connecting part to align the detonating grooves on adjacent charging tubes, the explosive force is further concentrated and the dispersion of explosive force is reduced.

[0025] 2. The positioning protrusions ensure that the emulsion explosive is centered and fixed in the filling space, thereby improving the uniformity of blasting;

[0026] 3. The use of heat shrink tubing facilitates the free adjustment of the amount of explosive buffer packing material, and the heat shrink tubing can further compress the packing material when subjected to the high temperature of the explosion, thereby prolonging the action time of the explosive gas and improving the blasting effect.

For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0038] Example 1:

[0039] This application provides a deep-hole blasting charging device, including: a charging tube 1, and a filling space is formed inside the charging tube 1;

[0040] The filling tube 1 also includes: a half-tube 100, of which there are two half-tubes 100, which can be spliced ​​together to form the filling tube 1, and the splice seam between the two half-tubes 100 forms a detonating groove 2; a positioning protrusion 3, which is disposed in the inner wall of the half-tube 100 for fixing the emulsion explosive filled in the filling space in a centered position; and a connecting part, which includes an extension groove part 4 and an extension tube part 5 respectively arranged at both ends of the half-tube 100.

[0041] The inner wall of the extension groove 4 is provided with an alignment slot 40, and the outer wall of the extension tube 5 is provided with an alignment strip 50. The alignment slot 40 can cooperate with the alignment strip 50 to align the detonating groove 2 on the adjacent charging tube 1.

[0042] Furthermore, the filling tube 1 is a conventional cylindrical tube, and the two half-tubes 100 are formed by dividing the filling tube 1 radially along the axial direction. The extension groove 4 and the extension tube 5 are arranged corresponding to the two half-tubes 100, and are also composed of two half-extension grooves and two half-extension tubes. The extension tube 5 can be inserted into the extension groove 4. Preferably, the half-tube 100 of the extension groove 4 is integrally formed. The extension groove 4 is formed by dividing the half-tube 100 by a concentric convex ring arranged on the inner wall of the half-tube 100. The outer diameter of the extension tube 5 and the inner diameter of the extension groove 4 are matched with each other. The alignment strip 50 and the alignment slot 40 are both distributed along the length direction of the filling tube 1. There are two alignment strips 50 and two alignment slots 40, which are symmetrically distributed radially along the filling tube 1.

[0043] In this embodiment, the filling tube 1 is formed by splicing two half-tubes 100, and the splice seam between the two half-tubes 100 forms the detonating groove 2. During the blasting process, the explosive force can be released preferentially through the detonating groove 2 and diffused in a directional manner, thereby concentrating the explosive force and reducing the phenomenon of explosive force dispersion. At the same time, when multiple filling tubes 1 are arranged at intervals in the deep hole, the extension groove part 4 and the extension tube part 5 cooperate with each other to align and join adjacent filling tubes 1, thereby aligning the detonating grooves 2 on adjacent filling tubes 1, further concentrating the explosive force and reducing the phenomenon of explosive force dispersion. At the same time, when the emulsion explosive is injected into the filling space, the positioning protrusion 3 can ensure that the emulsion explosive is centered and fixed in the filling space, thereby improving the blasting uniformity. Preferably, during the use of the filling tube 1, the emulsion explosive can be injected into the filling space in the two unassembled half-tubes 100 first, and then the two half-tubes 100 are assembled into the filling tube 1 before injecting the ammonium nitrate explosive.

[0044] Example 2:

[0045] This embodiment provides a deep-hole blasting charging device, which, in addition to the technical solution of the above embodiment, also has the following technical features, including: splicing groove 6, having two splicing grooves 6 and the two splicing grooves 6 being distributed on the splicing surface of the two half-pipes 100;

[0046] The two splicing slots 6 are respectively equipped with a locking block 7 and a locking groove 8. The two splicing slots 6 can be spliced ​​together and fixed by the cooperation of the locking block 7 and the locking groove 8.

[0047] It also includes: a positioning structure, which includes positioning protrusions 9 and limiting blocks 10 respectively arranged on the two semi-tube bodies 100;

[0048] The positioning protrusion 9 can cooperate with the limiting block 10 to align the two half-tubes 100 when they are spliced ​​together.

[0049] Furthermore, the splicing groove 6 is stepped, meaning that the splicing groove 6 has only two adjacent groove walls. Of the two splicing grooves 6, one splicing groove 6 is arranged on the inner wall side of one half-pipe 100 and extends along the length direction of the half-pipe 100. The locking block 7 is arranged on the side wall of the splicing groove 6, and there are several locking blocks 7, which are evenly spaced along the length direction of the half-pipe 100. The other splicing groove 6 is arranged on the outer wall side of the other half-pipe 100 and extends along the length direction of the half-pipe 100. The locking groove 8 is arranged on the side wall of the splicing groove 6 and its position corresponds to the position of the locking block 7 after the two half-pipes 100 are spliced. There are several locking grooves corresponding to the locking blocks 7.

[0050] The positioning protrusion 9 is arranged on the splicing groove 6 of one half-tube 100 located on the outer wall side of the two half-tubes 100. The positioning protrusion 9 is located on the inner wall side of the half-tube 100. There can be a number of positioning protrusions 9, which are evenly spaced along the length direction of the half-tube 100. The limiting block 10 is arranged on the inner wall side of the other half-tube 100. The limiting block 10 is in groups of two and there are several groups. The several groups of limiting blocks 10 are evenly spaced along the length direction of the half-tube 100, corresponding to the position of the positioning protrusion 9. In a group of limiting blocks 10, the interval between the two limiting blocks 10 matches the length of the positioning protrusion 9. The end of the limiting block 10 protrudes slightly into the splicing groove 6.

[0051] In this embodiment, during the splicing process of the two half-tubes 100, the two splicing grooves 6 cooperate with each other to combine the two half-tubes 100 into a filling tube 1. At the same time, during the splicing, the locking block 7 is inserted into the locking groove 8 to fix the two half-tubes 100 to each other. Meanwhile, the positioning protrusion 9 is embedded between the two limiting blocks 10 of a set to further align the two half-tubes 100 and limit the position of the two half-tubes 100 to prevent misalignment between the two half-tubes 100.

[0052] Example 3:

[0053] This embodiment provides a deep hole blasting filling device, which, in addition to the technical solution of the above embodiment, also has the following technical features, including: heat shrink tubing 11, which is disposed at the end of the filling space, and the two ends of the heat shrink tubing 11 can be heat-sealed to form a closed bag.

[0054] The heat-shrink tubing 11 forms a closed bag that is filled with a buffer medium 12.

[0055] The buffer medium 12 fills 85%-100% of the space of the closed bag formed by heat shrink tubing 11 and heat sealing.

[0056] Moreover, the heat shrink tubing 11 is made of conventional flexible heat shrink material.

[0057] In this embodiment, the heat shrink tubing 11, due to the lightweight nature of the heat shrink material, effectively reduces the weight of the filling tube 1 during empty transport, facilitating transportation. During on-site filling, one end of the heat shrink tubing 11 is first heat-sealed at high temperature. Then, the buffer medium 12 is filled into the heat shrink tubing 11 as needed. Due to the properties of the heat shrink material, the other end of the heat shrink tubing 11 can be heat-sealed freely according to the amount of buffer medium 12 filled, allowing users to handle different amounts of buffer medium 12. During the blasting process, the heat shrink tubing 11 can further compress the filled buffer medium 12 under the high temperature of the explosion, thereby prolonging the action time of the explosive gas and improving the blasting effect. Furthermore, the heat shrink material does not produce hard fragments during the blasting process, reducing the hazards generated by the blasting operation. By controlling the filling space of the closed bag formed by the heat-sealed heat shrink tubing 11 and the filling medium 12, air gaps can be reserved to further adjust the buffering effect.

[0058] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
