Description

Technical Field

[0001] This utility model relates to the field of explosive charging technology, specifically a continuous charging structure based on explosive technology. Background Technology

[0002] In blasting operations, continuous charging is a common charging method in which explosives are continuously loaded into the borehole until the designed charge is reached without any axial intervals.

[0003] Existing patent application number: 202021992302.9 A continuous charge structure includes blasting steps and boreholes regularly distributed on the blasting steps. The blasting steps have one or more layers. The boreholes are divided into two layers: a filling layer and a blasting layer. The blasting layer is filled with emulsion explosive and a detonator placed inside the emulsion explosive. The filling layer is set on the upper layer of the blasting layer. The continuous charge structure also includes a detonating cord. One end of the detonating cord is connected to the detonator inside the borehole, and the other end is placed outside the borehole. The boreholes are triangularly distributed on the blasting steps.

[0004] The aforementioned patent describes a continuous charging structure for blasting operations. During on-site charging, since the blast hole is filled with multiple explosive cartridges, the dispersed structure of the cartridges can easily cause them to get stuck somewhere inside the blast hole, preventing subsequent cartridges from reaching the intended charging position. Tools are needed to gently push and compact the cartridges, and the cartridges cannot be pre-assembled before being inserted into the blast hole, which is inconvenient. Therefore, we propose a continuous charging structure based on blasting technology to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a continuous charge structure based on blasting technology to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a continuous charging structure based on blasting technology, comprising a pre-charging device, wherein the pre-charging device comprises a blasting cylinder body, an upper cylinder section, an extension section, a lower cylinder section, and a compaction structure. The blasting cylinder body is composed of the upper cylinder section, the extension section, and the lower cylinder section being threadedly connected. The upper cylinder section has through structures at both ends, and the bottom end of the upper cylinder section is threadedly connected to the extension section. The extension section has through structures at both ends, and the bottom end of the extension section is threadedly connected to the lower cylinder section. The bottom end of the lower cylinder section is a closed structure. A compaction structure is provided on the inner side of the upper cylinder section.

[0007] Preferably, the pre-filled drug device is made entirely of non-metallic materials.

[0008] Preferably, the inner diameter of the upper cylinder section, the extension section and the lower cylinder section are the same, and the inner wall is smooth and burr-free.

[0009] Preferably, the extension sections can be connected by threaded connections at both ends.

[0010] Preferably, the compaction structure includes an internal thread, a threaded seat, a handle, and a pressure plate. The upper cylinder section has an internal thread, and a threaded seat is movably fitted inside the upper cylinder section. The surface of the threaded seat is threadedly connected to the internal thread. A handle is installed on the top of the threaded seat, and the bottom of the threaded seat is fixed to the pressure plate via a connecting rod. The pressure plate extends through the upper cylinder section into the extension section.

[0011] Preferably, the bottom edge of the upper cylinder section is provided with a wire outlet, the number of which is not less than two, and the wire outlets are evenly distributed along the bottom edge of the upper cylinder section.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model incorporates a pre-loading device. By loading explosive cartridges into the main body of the blasting cylinder and then leading out the blasting cord from the outlet, the explosive cartridges can be pre-assembled and inserted into the borehole using the blasting cylinder body. This prevents scattered explosive cartridges from getting stuck in some part of the borehole, ensuring that the explosive cartridges are loaded into the borehole in one go and improving the efficiency of the loading operation.

[0014] This invention features a compaction structure on the inner side of the upper cylinder section. After the explosive cartridge and the main body of the blasting tube are filled, the threaded seat is screwed into the upper cylinder section and connected to the internal thread by holding the handle. At this time, the pressure plate passes through the upper cylinder section and extends into the extension section to compact and seal the loaded explosive cartridge, preventing the explosive cartridge from moving on its own inside the blasting tube body, which would cause the explosive cartridge to fail to detonate at the designated position in the borehole.

[0019] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0020] Please see Figure 1-2This utility model provides a continuous charging structure based on blasting technology, including a pre-charging device 1. The pre-charging device 1 includes a blasting cylinder body 11, an upper cylinder section 111, an extension section 112, a lower cylinder section 113, and a compaction structure 12. The blasting cylinder body 11 is composed of the upper cylinder section 111, the extension section 112, and the lower cylinder section 113 connected by threads. The upper cylinder section 111 has through structures at both ends, and the bottom end of the upper cylinder section 111 is threadedly connected to the extension section 112. The extension section 112 has through structures at both ends, and the bottom end of the extension section 112 is threadedly connected to the lower cylinder section 113. The bottom end of the lower cylinder section 113 has a closed structure. The compaction structure 12 is provided on the inner side of the upper cylinder section 111.

[0021] To further explain, the bottom edge of the upper cylinder section 111 is provided with a wire outlet 13. There are no fewer than two wire outlets 13, and the wire outlets 13 are evenly distributed at the bottom edge of the upper cylinder section 111. The wire outlets 13 can be used to guide the blasting index out of the blasting cylinder body 11, which is convenient for wiring.

[0022] The pre-loaded explosive device 1 is made entirely of non-metallic material to prevent sparks and static electricity from being generated by friction with the explosive roll, thus ensuring safety.

[0023] The upper section 111, the extension section 112, and the lower section 113 have the same inner diameter and smooth inner walls without burrs, which prevents the explosive roll from getting stuck inside the blasting tube body 11 and ensures smooth loading.

[0024] The extension sections 112 can be connected by threaded connections at both ends. Users can add more extension sections 112 according to the charge requirements, so that the capacity of the blasting tube body 11 can be adjusted accordingly.

[0025] Specifically, by setting up a pre-loading device 1, before loading the explosives, the user can add the number of extension sections 112 according to the required amount of explosives, and adjust the capacity of the blasting tube body 11 accordingly. Then, the upper tube section 111, extension section 112 and lower tube section 113 are connected in sequence to form a complete blasting tube body 11. When loading the explosives, the explosive rolls are filled into the blasting tube body 11, and finally the blasting cord is led out from the outlet 13. Using the blasting tube body 11, the explosive rolls can be pre-assembled and then inserted into the borehole, avoiding the scattered explosive rolls from getting stuck in a certain place inside the borehole, ensuring that the explosive rolls are filled into the borehole in one go, and improving the efficiency of the loading operation.

[0026] Please see Figure 1-3This utility model provides a continuous charge structure based on blasting technology. The compaction structure 12 includes an internal thread 121, a threaded seat 122, a handle 123, and a pressure plate 124. The upper cylinder section 111 has an internal thread 121 inside, and the threaded seat 122 is movably sleeved inside the upper cylinder section 111. The surface of the threaded seat 122 is threadedly connected to the internal thread 121. The handle 123 is installed on the top of the threaded seat 122, and the bottom of the threaded seat 122 is fixedly installed to the pressure plate 124 through a connecting rod. The pressure plate 124 passes through the upper cylinder section 111 and extends into the extension section 112. The pressure plate 124 compacts and seals the loaded explosive cartridge, preventing the explosive cartridge from moving freely inside the blasting cylinder body 11 and thus preventing the explosive cartridge from detonating at the designated position in the blast hole.

[0027] Specifically, by setting a compaction structure 12 inside the upper cylinder section 111, after the explosive cartridge and the main body of the blasting tube 11 are filled, the handle 123 is held to screw the threaded seat 122 into the upper cylinder section 111 and screw it into the internal thread 121. At this time, the pressure plate 124 passes through the upper cylinder section 111 and extends into the extension section 112 to compact and seal the loaded explosive cartridge, so as to prevent the explosive cartridge from moving on its own inside the blasting tube main body 11, which would cause the explosive cartridge to fail to detonate at the designated position in the borehole.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
