Description
Technical field
The utility model relates to a kind of initiator device, belongs to mine blasting field, is specifically related to the unidirectional foldable tail swing device of a kind of upper centripetal deep hole hole-bottom blast tool.
Background technology
In mine blasting operation, hole-bottom blast uses more and more extensive in mine blasting, it utilizes fully with blasting energy, Blasting shock wave is little, meticulous segmentation can be subject to the favor of bargh, but igniting primer placement location has some change, also can change firing order in hole, bring unknown demolition effect.
Upward hole refers to the hole above passage, and its aperture is downward.
Detonate in set-up procedure at upper centripetal deep hole, detonator and igniting primer need to veer away at the bottom of hole from aperture, in order to ensure the safety in the process of veering away, need detonator and igniting primer to be placed in a safety guard, i.e. hole-bottom blast tool, comprise detonation tool main body and empennage, traditional hole-bottom blast tool empennage is fixed, as Fig. 2, this tail gear in use veers away together with detonation tool, in the process that veers away, empennage three pin open all the time, occur unexpected in process once veer away, when needing detonation tool to exit, because empennage three pin block, detonation tool to be taken out, the bending power of three pin of empennage must be overcome, this will use very large power, because detonator payment to a porter (detonating primer) connects detonator and igniting primer, if pullled energetically, very easily cause danger.
Summary of the invention
For solving the problem, the utility model discloses the unidirectional foldable tail swing device of a kind of upper centripetal deep hole hole-bottom blast tool, being specially adapted to igniting primer in the upper centripetal deep hole powder charge process of mine is placed at the bottom of hole, the parked more difficult situation of the larger primary explosive column in aperture, meets special circumstances and can exit not stuck smoothly.
For achieving the above object, the technical solution of the utility model is as follows:
The unidirectional foldable tail swing device of a kind of upper centripetal deep hole hole-bottom blast tool, comprise detonation tool and triangle empennage, described detonation tool comprises safety cap, charge shell, drain pan, described triangle empennage and drain pan link together, it is characterized in that: at triangle empennage each supporting leg 1/2, place is provided with one groove, slot opening is inside, in groove upper leg, is provided with draw-in groove.
Improve as one of the present utility model, described groove differs 1-2cm with draw-in groove height.
Improve as one of the present utility model, described triangle empennage is made up of rigid plastics.
The beneficial effects of the utility model are:
The unidirectional foldable tail swing device of a kind of upper centripetal deep hole hole-bottom blast tool described in the utility model, can send in process at the bottom of hole by detonation tool when upper centripetal deep hole powder charge, prevent detonation tool from automatically falling, meeting in particular cases empennage supporting leg under external force can bending, can exit not stuck smoothly, safety, convenient and practical.
Accompanying drawing explanation
Fig. 1 is working state figure of the present utility model.
Fig. 2 is the original schematic diagram of the utility model.
Fig. 3 is structural representation of the present utility model.
Fig. 4 is triangle empennage schematic diagram described in the utility model.
Reference numerals list:
1, blast hole is played, 2, detonation tool, 3, triangle empennage, 4, draw-in groove, 5, groove, 6, detonator payment to a porter, 7, safety cap, 8, charge shell, 9, drain pan.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.
As shown in the figure, first detonator is placed on detonation tool 2 internal fixtion good, then triangle empennage 3 device described in the utility model is arranged on detonation tool drain pan 9, and detonator payment to a porter 6 is fixed in the draw-in groove 4 of three legs successively, blend compounds band is fixed, triangle empennage 3 device described in the utility model is made up of rigid plastics, belong to loss product, tail gear described in the utility model has been arrived at the bottom of blast hole 1 hole with detonation tool 2, in the process that detonation tool 2 is upwards pushed up, the leg of triangle empennage 3 is slightly inwardly curved by groove 5, convenient advance, then powder charge in hole is carried out with grug transportation tube, now can not tear detonator payment to a porter, ensure during powder charge that all legs are in non-folded state, until powder charge is loaded complete smoothly, occur surprisingly if detonation tool 2 has been sent in process at the bottom of blast hole 1 hole, as big gun hole blocking etc., detonation tool 2 is needed to exit, detonator payment to a porter 6(pulling force is drawn in safe allowed band) with have gentle hands, groove 5 described in the utility model highly differs 1-2cm with draw-in groove 4, because detonator payment to a porter 6 is fixed in the draw-in groove 4 of three legs successively, blend compounds band is fixed, supporting leg is under the effect of pulling force downward vertically, produce the pulling force that vertical leg is downward, this power makes supporting leg collapsible place disequilibrium bending or supporting leg occur rupture to putting down vertically downward at groove 5 place, and then disequilibrium, supporting leg occurs folding, then detonation tool 2 can smoothly outside exit aperture under Gravitative Loads, safety, convenient and practical.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic.
