Description

Technical Field

[0001] This invention relates to the field of explosive loading systems, and in particular to a remote-controlled hole-finding loading system and method for on-site mixing of emulsion explosives. Background Technology

[0002] In open-pit blasting, explosives are typically transported to the blast hole via a mixed-load vehicle. When loading explosives through a charging pipe, the charging pipe needs to be inserted into the blast hole.

[0003] For example, document CN117928324A discloses an intelligent borehole-finding device for an open-pit emulsion explosive mixing vehicle. The solution "includes a mixing vehicle, with a winding drum mounted on the rear of the vehicle. A charging tube is wound around the winding drum, and a guide assembly is mounted on one end of the charging tube. The guide assembly includes a guide frame connected to the charging tube, and multiple guide balls are mounted in the middle of the guide frame. This invention, by installing a guide assembly on the charging tube, effectively reduces jamming during the descent when inserted into the borehole, improving the insertion efficiency of the charging tube." The intelligent borehole-finding device for the open-air emulsion explosive mixing truck transmits images to the cab via a camera. The driver adjusts the position of the mixing truck so that the charging tube is directly above the borehole, facilitating borehole finding and charging. The guiding components include a guide frame connected to the charging tube, with multiple guide balls installed in the middle of the guide frame and multiple attitude adjustment components installed at the bottom of the guide frame. The attitude adjustment components are evenly distributed, and during the descent, the overall descent position can be adjusted by the attitude adjustment components in different positions, reducing jamming and making borehole finding and charging more convenient. The guide balls are located between the borehole wall and the charging tube during the descent, making the descent even more convenient.

[0004] The above-mentioned solution improves the smoothness of the propellant tube's entry into the borehole and avoids jamming by using a guide ball in the guide assembly to contact the inner wall of the borehole. However, this process has several drawbacks. First, when the guide ball contacts the inner wall of the borehole, dust and other impurities can adhere to it and cause it to jam, significantly reducing its guiding effect. Second, the guide ball is difficult to disassemble, install, and clean. Third, the position of the guide ball is not adjustable, resulting in low adaptability to boreholes of different diameters.

[0005] To address these issues, this invention proposes a remote-controlled hole-finding loading system and method for on-site mixing of emulsion explosives. Summary of the Invention

Detailed Implementation

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-8 A remote-controlled hole-finding loading system for on-site mixed emulsion explosives includes a loading tube 1 and a loading ring 2 sleeved on the loading tube 1. A collar 21 is fixedly installed at the bottom of the loading ring 2, and a mounting hole 22 is provided on the collar 21. The collar 21 is fixed to the drug loading tube 1 by screws. The loading ring 2 is provided with a receiving cavity 23 and a charge guiding assembly is provided in the receiving cavity 23; the charge guiding assembly is regulated by a set control component.

[0023] According to the appendix Figure 1 - Appendix Figure 5 As shown, the guide ball 307 in this scheme provides guidance for the drug delivery operation of the drug delivery tube 1.

[0024] The use of guide ball 307 serves several purposes. First, the guide ball 307 is installed through the cooperation of support body 304, placement cavity 305, and limiting cap 401, making it easy to disassemble and reassemble. Second, a cleaning brush 503 is provided at the end of the limiting cap 401 to clean dust and other impurities adhering to the guide ball 307 during its rolling operation, thus preventing the guide ball 307 from getting stuck. Furthermore, this solution uses a control component to adjust the position of the guide ball 307 according to the borehole diameter. In other words, the diameter of the annular guide ball 307 is adapted to the borehole, and the position of the guide ball 307 is adjusted by rotating the internal thread control ring 601; thus, it has better operational flexibility.

[0025] Regarding the use of the collar component 21, the receiving cavity 23 set in the collar component 21 is set as an annular cavity, and a threaded connection part 24 is provided on the side of the receiving cavity 23 near the center of the ring; the charge guiding assembly in this solution includes a movable insert shaft 301 that is equidistantly and movablely inserted into the side wall of the loading ring 2; one end of the movable insert shaft 301 is located in the receiving cavity 23, and the other end of the movable insert shaft 301 is located outside the loading ring 2. A fixed plate 302 is fixedly set on the outer wall of the movable insert shaft 301 located in the receiving cavity 23. An auxiliary spring 303 is fixedly set on one side of the fixed plate 302, and the other end of the auxiliary spring 303 is fixedly set on the side wall of the receiving cavity 23; a support body 304 is fixedly set on the outer end of the movable insert shaft 301; a placement groove 305 and an external threaded connecting ring 306 are provided at the end of the support body 304. The placement groove 305 is used to place the guide ball 307.

[0026] The installation of the guide ball 307 requires the use of an auxiliary component, which includes a limiting cap 401 that mates with the support body 304. An internally threaded connecting ring 402 is fixedly mounted at one end of the limiting cap 401, and this internally threaded connecting ring 402 is threadedly connected to an externally threaded connecting ring 306. In other words, the guide ball 307 is installed by using the limiting cap 401 in conjunction with the support body 304. The guide ball 307 is placed in the placement groove 305 on the support body 304, and then the internally threaded connecting ring 402 on the limiting cap 401 and the externally threaded connecting ring 306 on the support body 304 are threadedly connected. The guide ball 307 then moves within the placement groove 305.

[0027] When the guide ball 307 needs to be disassembled, simply rotate the limit cap 401 until it is removed. During this process, rotate the limit cap 401 until the threaded connection between the internal threaded connecting ring 402 and the external threaded connecting ring 306 is released. Then remove the limit cap 401 and take the guide ball 307 out of the placement cavity 305.

[0028] Combined with the appendix Figure 6 - Appendix Figure 8 As shown, the guide balls 307 arranged in a ring at equal intervals provide guidance for the propellant tube 1. During this process, dust and other impurities inevitably adhere to the guide balls 307, which may cause them to jam after prolonged operation.

[0029] Therefore, this solution also provides a loading slot 501 at the outer end of the limiting cap 401; the loading slot 501 is annular, and an elastic retaining ring 502 is fitted and engaged in the loading slot 501, and a cleaning brush 503 is provided on the elastic retaining ring 502; the cleaning brush 503 is annular; the brush body of the cleaning brush 503 is tilted.

[0030] In other words, during the rolling process of the guide ball 307, the dust and other impurities adhering to it will be cleaned by the cleaning brush 503 to ensure the smooth operation of the guide ball 307, thereby ensuring the hole-finding and guiding work of the charge tube 1.

[0031] Then from the appendix Figure 2 - Appendix Figure 5 As shown, the position of the guide ball 307 is adjusted according to the size of the borehole diameter, that is, the diameter of the annular guide ball 307 needs to be adapted to the borehole.

[0032] This solution is achieved through a set adjustment component, which includes an internal thread adjustment ring 601 that is threadedly connected to the threaded connection part 24; a drive groove 602 is provided at equal intervals on the outer side wall of the internal thread adjustment ring 601, and the drive groove 602 is positioned corresponding to the movable insertion shaft 301 in the side wall of the loading ring 2 and has the same number of sets.

[0033] By rotating the internal thread adjusting ring 601, the drive groove 602 is driven to squeeze one end of the movable insert shaft 301, causing the support body 304 at the other end of the movable insert shaft 301 to extend outward, which in turn drives the guide ball 307 to extend outward. During this process, the auxiliary spring 303 connected to the fixed plate 302 is in a compressed state. When it is necessary to retract the guide ball 307, the internal thread adjusting ring 601 is rotated in the opposite direction, so that the squeeze of the drive groove 602 on the movable insert shaft 301 is gradually released. At this time, the support body 304 retracts under the retraction action of the auxiliary spring 303.

[0034] To ensure the stability of the guide ball 307 adjustment, this solution uses a positioning structure, which includes an auxiliary convex plate 701 fixedly mounted on one side of the top of the internal thread adjustment ring 601. A positioning screw 702 is threadedly connected to the auxiliary convex plate 701, and a handle 703 is fixedly mounted on the top of the positioning screw 702. The positioning structure also includes a positioning groove 704 mounted on the top of the loading ring 2. The positioning groove 704 is equidistantly arranged in an arc shape.

[0035] That is, after the position of the guide ball 307 is adjusted, the positioning screw 702 is used for positioning. During this process, the positioning screw 702 is rotated by the handle 703 until the bottom of the positioning screw 702 is engaged with the positioning slot 704 at the corresponding position.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
