Bidirectional anti-skid device for blasting charge

Abstract

The invention discloses a bidirectional anti-skid device for blasting charge. The bidirectional anti-skid device for the blasting charge comprises a guide rod, a supporting assembly and a control assembly, wherein the supporting assembly comprises a plurality of fixing pieces, a plurality of supporting rods, a plurality of supporting elastic pieces, a first axial ring and a second axial ring, one ends of the plurality of fixing pieces are pivoted to the first axial ring, the first ends of the plurality of supporting rods are pivoted to the second axial ring, the second ends of the plurality of supporting rods are hinged to the middles of the fixing pieces in a one-to-one correspondence mode, the first ends of the plurality of supporting elastic pieces are connected with the peripheral surface of the guide rod, the second ends of the plurality of supporting elastic pieces are hinged to the second ends of the supporting rods together in a one-to-one correspondence mode, and the control assembly is used for controlling the second axial ring to be away from or close to the first axial ring in the axial direction of the guide rod. The bidirectional anti-skid device for the blasting charge has the characteristics of being simple in structure and high in reliability.

Description

technical field [0001] The invention relates to the technical field of mine blasting engineering, in particular to a two-way anti-skid device for blasting charges. Background technique [0002] When drilling explosives in mine roof blasting operations, anti-skid devices are often installed at the end of the single-stage explosives to load explosives, but such devices can only move forward and cannot retreat. When stuck halfway, it is difficult to handle, and safety accidents such as punching are prone to occur. Contents of the invention [0003] This application is made based on the inventor's discovery and recognition of the following facts and problems in the related art. [0004] In the related art, a spring member or a disposable support member is often used for single-stage explosive loading. However, the inventors of the present application have discovered and realized through research that the spring or disposable support can only push the explosive forward throug...
