Description

Technical Field

[0001] This utility model relates to the field of mining construction technology, specifically to a high-efficiency charging device for deep-hole blasting. Background Technology

[0002] The existing workers need to feed the explosive rolls one by one into the blast holes that are tens of meters deep, which is labor-intensive and time-consuming.

[0003] During the process, improper operation or falling stones can easily cause blockage of the hole. Dealing with blockage is extremely dangerous, or manually tamping the explosives may cause premature detonation due to friction and impact. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency charging device for deep-hole blasting. The entire charging process does not require manual tamping of the explosives, eliminating the hidden danger of premature detonation caused by friction and impact. The hydraulic system thrust is stable and controllable, avoiding the explosives from being subjected to violent mechanical action, thus ensuring the safety of operators and construction sites from the source and solving the problems in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency charging device for deep-hole blasting, comprising a charging platform, a charging coupling shaft, and a pre-embedded sleeve. A pressure plate is installed above the charging platform, and the pressure plate is connected to the charging platform via a spring support shaft, which is telescopically connected to the charging platform. A handle is fixed to the outer surface of the pressure plate by screws, and a hydraulic cylinder is installed at the bottom of the pressure plate by screws. A telescopic push rod is installed inside the hydraulic cylinder, and the telescopic push rod extends to the bottom of the charging platform.

[0006] With the above scheme, the loading platform serves as the working load base, and a pressure plate is installed on top of it. The two are elastically connected by a spring support shaft, which can extend and retract relative to the loading platform, playing a role in buffering and resetting.

[0007] Preferably, the loading platform is equipped with support legs around its perimeter, wherein one end of the support legs is rotatably connected to the loading platform, and the other end of the support legs is equipped with a rubber pad.

[0008] Preferably, the telescopic push rod is configured as a multi-segment telescopic structure.

[0009] Preferably, one end of the telescopic push rod is equipped with a locking pin, and the locking pin is connected to the telescopic push rod via an internal thread.

[0010] Preferably, one end of the filling shaft is fitted with an integrally formed retaining shaft, and the other end of the filling shaft is provided with a locking groove.

[0011] Preferably, the filling shafts are connected by a retaining pin and a locking groove.

[0012] The above scheme, which uses a spliced ​​charging coupling, allows for flexible adjustment of the charging length according to the borehole depth. Combined with a hydraulic system for rapid advancement, the charging process is continuous and smooth, significantly reducing the time required compared to manual operation and thus accelerating the construction progress.

[0013] Preferably, the pre-embedded sleeve has an inner filling cavity, and the filling coupling extends into the inner filling cavity.

[0014] With the above solution, the pre-embedded sleeve is inserted into the blast hole before the explosive is loaded, forming a smooth and solid inner wall protection, effectively isolating the hole wall from falling debris, fundamentally avoiding the occurrence of hole blockage, and reducing the high-risk operation links caused by dealing with hole blockage.

[0015] Preferably, the filling coupling is connected to the locking pin and the telescopic push rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model addresses the issue that traditional manual loading requires workers to push explosives one tube at a time, which is physically demanding and inefficient. This device, through hydraulic drive and mechanized pushing, achieves continuous and automated loading, significantly reducing the physical burden on workers, and is especially suitable for deep-hole blasting applications at depths of tens of meters.

[0018] 2. With this utility model, the entire charging process does not require manual tamping of the explosives, eliminating the hidden danger of premature detonation caused by friction and impact. The hydraulic system thrust is stable and controllable, avoiding the explosives from being subjected to violent mechanical action, thus ensuring the safety of operators and construction sites from the source.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To address the current issues of workers manually feeding cartridges of explosives into boreholes tens of meters deep—a labor-intensive and time-consuming process; the risk of blockages due to improper handling or falling rocks, which are extremely dangerous to handle; and the potential for premature detonation due to friction and impact when manually tamping the explosives—please refer to [the relevant documentation / reference]. Figure 1-2 The present invention provides the following solution:

[0024] A high-efficiency deep-hole blasting charging device includes a charging platform 1, a charging coupling 2, and a pre-embedded sleeve 3. A pressure plate 101 is installed on the top of the charging platform 1. The pressure plate 101 is connected to the charging platform 1 by a spring support shaft 104, and the spring support shaft 104 is telescopically connected to the charging platform 1. A handle 1011 is fixed to the outer surface of the pressure plate 101 by screws. A hydraulic cylinder 102 is installed at the bottom of the pressure plate 101 by screws. A telescopic push rod 1021 is installed inside the hydraulic cylinder 102, and the telescopic push rod 1021 extends to the bottom of the charging platform 1.

[0025] Support legs 103 are installed around the loading platform 1. One end of the support legs 103 is rotatably connected to the loading platform 1, and the other end of the support legs 103 is equipped with a rubber pad. The telescopic push rod 1021 is set as a multi-segment telescopic structure. One end of the telescopic push rod 1021 is equipped with a locking pin 1022, and the locking pin 1022 is connected to the telescopic push rod 1021 through an internal thread.

[0026] In this embodiment, before loading the explosive, the pre-embedded sleeve 3 is first placed into the borehole to prevent rocks from falling from the borehole wall and causing blockage. Then, according to the depth of the borehole, the corresponding number of loading shafts 2 are sequentially spliced ​​with the locking shaft 201 and the locking groove 202 to form an integral delivery column. The column is then inserted into the inner filling cavity 301 of the pre-embedded sleeve 3 so that its lower end is close to the bottom of the borehole.

[0027] The operator presses down on the pressure plate 101 using the handle 1011, causing the hydraulic cylinder 102 and the telescopic push rod 1021 to move downwards. Under hydraulic drive, the telescopic push rod 1021 extends section by section, and the locking pin 1022 at its end locks with the locking groove 202 of the uppermost charging coupling 2, thereby transmitting axial thrust to the entire charging coupling tandem. As the push rod continues to press down, the explosive is smoothly and continuously pushed to the bottom of the borehole under the guidance of the charging coupling 2, and the pressure is properly controlled to achieve dense filling of the explosive, avoiding gaps.

[0028] One end of the filling shaft 2 is equipped with an integrally formed clamping shaft 201, and the other end of the filling shaft 2 is provided with a locking groove 202. The filling shafts 2 are connected by the clamping shaft 201 and the locking groove 202. The inside of the pre-embedded sleeve 3 is provided with an inner filling cavity 301, and the filling shaft 2 extends into the inside of the inner filling cavity 301.

[0029] In this embodiment, the charging coupling 2 is a charging execution component. One end of it is provided with an integrally formed retaining shaft 201, and the other end is provided with a locking groove 202. Multiple charging couplings 2 can be quickly spliced ​​together by the cooperation of the retaining shaft 201 and the locking groove 202 to form a continuous charging channel that adapts to different borehole depths.
