Description
Technical field
The utility model relates to industrial explosive materials fields, specifically a kind of to remove explosive charge channel effect
Chuck.
Background technique
Drillhole blasting is the common method of mining and tunnel piercing.However in some engineering explosions, explosive is in big gun
The remaining phenomenon in part is generated after the explosion of hole, the reason is that when there are quick-fried in the powder column that when gap, explodes between powder stick and blasthole wall
Hong wave, which is propagated, to be occurred from behavior is inhibited, and energy is gradually decayed until the generation miss-fired, is usually known as groove effect for above-mentioned phenomenon
It answers.
About channel effect, there are two types of explain for engineering circles: first is that the air between detonation product compression powder stick and hole wall, produces
Raw air-shock wave, it is ahead of detonation wave and compresses powder stick, thereby inhibits the propagation of detonation wave in explosive；Second is that explosive rises
A plasmasphere is generated in the front of detonation wave front after quick-fried, so that compression is generated to unreacted powder stick surface layer below,
The complete reaction of this layer of explosive is interfered, plasmasphere density is bigger, is just more obvious to the compression of not quick-fried powder column, can draw when serious
Play miss-firing for unreacted explosive.It can be seen that gap caused by blasthole Uncoincided charge is the original for causing channel effect to generate
Cause.
In order to avoid the generation of channel effect in engineering explosion, the structural shape to powder charge in blasthole is needed to improve.
For this purpose, under the premise of not influencing powder charge, designing the structure that air-shock wave or plasmasphere are propagated in a kind of obstruction blasthole is
It is highly desirable.
Utility model content
The utility model is intended to provide a kind of chuck that can remove explosive charge channel effect, both can guarantee that blasthole did not coupled
Powder charge, and blasthole clearance air shock wave or plasmasphere can be stopped to propagate the channel effect generated.
In order to solve the above technical problems, the technical solution adopted in the utility model are as follows: one kind can remove explosive charge ditch
The chuck of the effect of grooves, in a ring and the chuck body that can be sleeved on outside cylindrical explosive including shape, in chuck body radially
It offers through slot, is equipped in the corresponding position through slot of chuck body outer rim for adjusting and fixing the locking through groove width
Button；The inner edge of chuck body is equipped at intervals with multiple spines in multiple pluggable cylindrical explosives；It is also opened in the disk of chuck body
The through-hole passed through equipped with the payment to a porter for detonating capsule.
Preferably, tight locking button includes two protrusions and use that chuck body outer rim is arranged in and is located at through slot two sides
Two raised bolts are fixed in series connection, perforation is offered in a protrusion wherein, offers and perforate in another protrusion
Threaded hole corresponding and for being coupled for bolt.
Preferably, two protrusions are integrally formed with chuck body.
Preferably, the quantity of spine is three, and three spines are evenly spaced in the inner edge of chuck body.
Preferably, spine is integrally formed with chuck body.
Preferably, through-hole is provided in chuck body the position opposite with slot is run through.
Preferably, chuck body is made of PVC material.
Beneficial effect
The spine of chuck body inner edge can be inserted in cylindrical explosive in the utility model, and extending radially through groove width can adjust
Save the degree that chuck body compresses cylindrical explosive so that after cylindrical explosive is ignited in blasthole, leader shock waves or wait from
Sublayer can become sparse or diverging under the interference of chuck body disk, the compression to not quick-fried part cannot be formed, thus guaranteeing
While blasthole Uncoincided charge, the generation of channel effect is avoided.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the scheme of installation of the utility model in the application；
Marked in the figure: 1, through-hole, 2, chuck body, 3, spine, 4, tight locking button, 401, bolt, 402, protrusion, 5, run through
Slot, 6, detonating capsule, 7, blasthole, 8, payment to a porter, 9, cylindrical explosive, 10, stemming envelope.
Specific embodiment
As shown in Figure 1, one kind of the utility model can remove the chuck of explosive charge channel effect, including shape is in a ring
And using the chuck body 2 of PVC material production.In the application, cylindrical explosive 9 can be set in by the inner hole of chuck body 2
Periphery.
It is radially offered in chuck body 2 through slot 5, by adjusting the width through slot 5 to adjust chuck body 2
The diameter of inner hole, and then chuck body 2 is tightly placed on cylindrical explosive 9.For the ease of adjusting width and the fixation through slot 5,
2 outer rim of chuck body is equipped with tight locking button 4 in the corresponding position through slot 5.Tight locking button 4 in the present embodiment includes being arranged in chuck
2 outer rim of ontology is simultaneously located at through two protrusions 402 of 5 two sides of slot and for the bolt for fixing two protrusions 402 of connecting
401.Perforation is offered in a protrusion 402 wherein, offer corresponding with perforation in another protrusion 402 and is used for for spiral shell
The threaded hole that bolt 401 is coupled.The small end of bolt 401 first passes through perforation and is then threaded into threaded hole, is revolved by bolt 401
Enter the depth in threaded hole to adjust and fix the width through slot 5.
It can be inserted into multiple spines 3 in cylindrical explosive 9 there are three setting in the inner edge uniform intervals of chuck body 2.In chuck
The through-hole 1 passed through for the payment to a porter 8 of detonating capsule 6 is also provided with through the opposite position of slot 5 in the disk of ontology 2.
As shown in Fig. 2, being set with chuck body 2 in each 9 medium position uniform intervals of cylindrical explosive first, adjustment runs through slot
5 width, so that spine 3 is inserted into 9 body of cylindrical explosive, and screwing bolts 401 are fixed；Secondly detonating capsule 6 is inserted into first segment
Powder charge, through-hole 1 of the payment to a porter 8 in chuck body 2 are successively pierced by；Then above-mentioned concatenation explosive column is pushed into blasthole 7, and uses big gun
Mudding 10 blocks blasthole 7；The payment to a porter 8 in multiple blastholes 7 is finally connected into detonation, completes bursting work.
