Description
Technical field
A kind of powder column housing is the utility model is related to, especially a kind of one side notched blasting powder column housing.
Background technology
When Underground Engineering Blasting is constructed, periphery hole charge explosion can cause to retain crack propagation and damage in rock mass, at present
Retain rock mass for protection, have a series of research on charge constitution and explosive selection, this is to a certain extent
Reduce the degree of injury for retaining rock mass.But the periphery hole explosion for some specific conditions still can not meet, such as rock lane
Trace integration mechanized development machine (abbreviation fully-mechanized digging machine) runs into solid rock when constructing, and crack in rock mass need to be caused to expand using explosion
Exhibition, in favor of fully-mechanized digging machine Cutting Rock.In order to both more efficiently cause crack propagation in rock mass, and can protection retains rock mass,
It is badly in need of a kind of new notched blasting powder column now.
The content of the invention
The utility model provides a kind of one side notched blasting powder column housing, has both solved because solid rock country rock clipping is made
The problem of with causing demolition effect bad, reservation Rock Damage destruction of the explosion to surrounding is reduced again.
Technical scheme is used by the utility model:
A kind of one side notched blasting powder column housing, including connecting connection parts (1), powder column housing (2), bottom connection on powder column
(3) three major parts of device, below described " upper and lower " refer to the position relationship in Figure of description.
The powder column housing (2) is camcylinder structure, and grooving seam (4), grooving seam (4) length are provided with cylinder thin-walled side
Equal to powder column shell length, powder column housing (2) heavy wall upper lateral part is provided with upper connecting connection parts (1), and bottom is provided with bottom connection dress
Put (3).
The upper connecting connection parts (1) have two parts, and top is a part for spheroid, and bottom is that a diameter is less than ball
The cylinder of body, and a hemispheric groove is set at 45 degree of the top of spheroid, powder column housing can be fixed, be unlikely to
Rotate.
The lower connecting connection parts (3) are the ball-type groove to match with upper connecting connection parts (1), and oblique 45 degree of directions are set
A raised hemisphere is put, is matched with the hemispherical groove of upper connecting connection parts (1), is revolved after avoiding two powder column connections
Turn, grooving seam (4) dislocation.
The grooving seam (4) is located at cylinder thin-walled side, can be a seam or two seams.
Cut slot length for described one and be equal to powder column shell length.
Two groovings are sewn on thin-walled side and are arranged symmetrically, and it is shorter 3cm than powder column shell length to cut slot length.
Operation principle:
The utility model has carried out eccentric processing to traditional cylindrical powder pellet, and sets grooving to stitch in plane of weakness, for blast
Product provides guide effect.Powder column explosion time, explosion product can act preferentially on rock at grooving seam, cause grooving seam rock nearby
Stone ruptures, and is advantageous to follow-up fully-mechanized digging machine cutting.Meanwhile camcylinder structure can play a protective role to the rock mass of heavy wall side.
Compared with prior art, the utility model has the advantages that;
Inner chamber is carried out eccentric processing by the utility model on cylindrical powder pellet, heavy wall side and thin-walled side is formed, in thin-walled side
Set grooving to stitch, the rock breaking capacity of powder column can be both improved compared with comparable size powder column, can protect again and around retain rock mass.
Powder column explosion time, explosion product can form cumulative effectiveness at grooving seam, many so as to be produced on the rock near grooving seam
Crackle, explosion product can act preferentially on rock at grooving seam, cause grooving seam nearby rock rupture and to add crack
Spreading range so that the rock under fully-mechanized digging machine cutting is in bulk, rather than powdered, raising cutting efficiency, improvement construction operation
Environment.And more than two the utility model powder columns can fast and effectively be connected by both ends upper and lower part attachment means
Connect, and limit the rotation between powder column, ensure the uniformity in powder charge total length grooving direction.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are clearer, below in conjunction with accompanying drawing to this practicality
New embodiment is expanded on further:
A kind of one side notched blasting powder column housing, including connecting connection parts (1), powder column housing (2), bottom connection on powder column
(3) three major parts of device;
The upper connecting connection parts (1) are a raised ball-type, and bottom is slightly less than the circle of sphere diameter by a diameter
Cylinder connects with powder column housing, and in order to make two powder column housings firmly connect, one is set at 45 degree of the top of spheroid
Hemispheric groove;
The powder column housing (2) is an off-centre operation cylinder, plane of weakness is formed in side, and set grooving to stitch in thin-walled side
(4);
The lower connecting connection parts (3) are the ball-type groove to match with upper connecting connection parts (1), and oblique 45 degree of directions are set
A raised hemisphere is put, it is just mutually nested with upper connecting connection parts, it is easy to be connected with each other between powder column and powder column, and make medicine
Connect more stable between post, be unlikely to rotate, ensure that the grooving seam of multiple powder columns is in same straight line all the time.
Utility model works mode is described further with reference to accompanying drawing:
As shown in figure 1, powder column intracavitary can be directly loadable into explosive, installing medicine can be sequentially connected, and upper connecting connection parts 1 are with
Connecting connection parts 3 are a combination, are filled in after connecting powder column in blasthole, and powder column grooving seam uniform alignment is wanted to the rock of explosion
It face, because 45 degree of directions of attachment means have a hemisphere to set, effectively can prevent powder column from rotating, grooving seam is in all the time
Same straight line.Load detonating capsule in big gun head powder column;
One side notched blasting powder column housing processing and fabricating of the present utility model is very simple, and by specification accompanying drawing, which makes, is
Can, connecting portion makes will relatively accurately, in order to quickly be connected between powder column;
The utility model powder column mainly uses in periphery hole explosion, without setting top pressure closure and sealing bottom, makes
Simply, it is easy to operate.
