A long-distance blasthole charging device and charging method

Abstract

The invention discloses a long-distance blasthole charging device and a charging method using the charging device, and relates to the technical field of blasthole charging. an arc-shaped groove; an outer cylinder, which is spliced ​​by a plurality of arc-shaped plates, and the outer cylinder is sleeved outside the inner cylinder, and an annular gap is formed between the two; a plurality of fan-shaped plates, the outer of each fan-shaped plate The arc surfaces are fixedly connected with the inner surfaces of the respective corresponding arc plates, and each sector plate is embedded in its corresponding arc groove, and the inner arc surfaces of the plurality of sector plates form a round hole; the elastic block, each sector plate An elastic block is arranged between the inclined side and the inner wall of the arc-shaped groove; the circular wedge has a certain taper along its axial direction, and the inner wall of the circular hole fits the outer wall of the circular wedge; the connecting rope connects The rope passes through the small end of the circular wedge; the pipe body, and one end of the pipe body is embedded in the annular gap. The charging time is short by adopting the charging device, and the charging quality is good.

Description

technical field [0001] The invention relates to the technical field of blast hole charging, in particular to a long-distance blast hole charging device and a charging method. Background technique [0002] Deep hole blasting technology is used in mining engineering, tunnel engineering and water conservancy engineering. As the application of deep hole blasting technology becomes more and more common and gradually matures, people pay more and more attention to the charging method and safety issues. Blast hole charging is an important link in the blasting construction of roadways, tunnels, etc. However, due to the lack of corresponding charging tools for long-distance blast hole charging, it takes a long time to charge the charge, which is easy to delay the construction period, and the quality of the charge is poor, which affects Blast effect. [0003] Therefore, how to provide a long-distance blasthole charging device to shorten the charging time and improve the charging qual...
