Abstract

The invention discloses an umbrella-shaped detent hanger. An umbrella framework structure is used for reference, elastic rope yarns or springs are mounted to make surface frames have the unfolding trend, and a hanging fixed pulley is further arranged at the lower end of the structure. When the umbrella-shaped detent hanger is matched with a charging long bag for charging an upward or horizontal or downward gently inclined deep blind hole with the enlarged hole bottom, the umbrella-shaped detent hanger is clamped at the hole bottom, the charging long bag is dragged into the blast hole through a rope winds around the fixed pulley, breakage and deformation of a blasting charge can be avoided, accurate spacing charging and non-coupling charging are achieved, and the problems of charging and blockage of upward or horizontal or downward gently inclined deep blind holes are solved. The umbrella-shaped detent hanger is simple in structure and wide in available material source, and mass industrial production and usage are easy. The construction method provided by the invention is wide in application range and can be widely used for projects of demolition blasting, soil and rock blasting, controlled blasting and mine blasting, and the technical scheme with the high cost performance is provided for deep hole charging.

Description

technical field [0001] The invention belongs to the field of blasting engineering, and in particular relates to an umbrella-shaped clamping hanger and a method for charging a blasthole by using the umbrella-shaped clamping hanger. Background technique [0002] In blasting engineering, the upward, horizontal and downward slopes are gently inclined (slow inclination means that the inclination angle of the blasthole is less than the angle at which the charge can slide into the blasthole by gravity, generally less than 30°) and deep blind holes (blind holes refer to the blastholes). One end of the hole is open) charging is a difficult problem, especially in the occasions where spaced charges and uncoupled charges are required. For horizontal or gently inclined blind holes, there are two common charge methods, one is to push the charge pack (or charge roll) and the spacer (such as waste paper) into the blast hole piece by piece with rods. The efficiency of the method is low, and...
