Description
Technical field
The present invention relates to a kind of powder column housing, particularly relate to a kind of spiral energy collecting type slotting powder column housing.
Background technology
Unfavorable factor in Cut Blasting has 2: one to be that the scope of freedom is single, and rock volume in shattering process is swollen
Swollen, single degree of freedom face cannot provide sufficient expansion space to be the main cause causing slotting effect poor；Two are
The clamping action of rock mass, along with mining depth increases, in Cut Blasting, the clamping action between rock block shows
Writing and increase, this is another unfavorable factor of Cut Blasting.At present, in order to realize stone head speedy drivage
Through having carried out a series of research work, this improves cyclic advance to a certain extent, but to how to overcome draws
Unfavorable factor in groove explosion, the research improving blast hole utilizing factor is the most deep enough, in terms of explosion powder column, just
Need badly and develop a kind of saving explosive, the slotting powder column that slotting is effective.
Summary of the invention
In order to overcome the scope of freedom in current Cut Blasting single and the unfavorable factor such as rock clamping action, the present invention
A kind of spiral energy collecting type slotting powder column housing is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of spiral energy collecting type slotting powder column housing, including top pressure closure (1), powder column body (2), seals bottom
(3) three major parts, described below " up and down " refers to the position relationship in Figure of description；
Described top pressure closure (1) is concave plastic closure, and inner lid has two tower grooves, outer wall
On have two tower projections, bottom is hemispherical, directly covers on powder column body (2) top；
Described powder column body (2) is cylindrical empty cavity rod body, for PVC material, triangle spiral shell is distributed on the body of rod
Rotating groove (4), channel section is shaped as triangle, and the shank diameter containing the spiral groove of triangle is less than
Without the diameter of groove, powder column body (2) upper end inwall there are two tower grooves, it is simple to sealing pushed up
Lid (1) is connected to powder column body (2) upper end, it addition, have two diametrically on powder column body (2) top
Circular port (5), bottom inwall is female thread, it is simple to will seal bottom (3) be connected to powder column body (2)
Bottom；
It is provided with metal energy gathering cap (6) housing of same shape in described spiral groove (4), is close to spiral
On formula groove (4) wall；
Described sealing bottom (3), outer wall has two tower projections, and bottom is hemispherical, seals bottom (3)
Top is external screw thread, seals and is attached by screw thread between bottom (3) and powder column body (2)；
Operation principle:
The present invention is to arrange the spiral groove of triangle on traditional cylindrical powder column, pastes same shape above groove
Metal energy gathering cap, according to the principle of jet perforating, powder column explosion time, when detonation wave arrives metal cumulative cover
Time, metal cap is owing to by strong compression, inner surface portion metal is squeezed out, along the spiral groove of triangle
At a high speed outwards jet, energy is concentrated most, is had higher orientation width generation capacity, at the spiral groove of triangle
Region forms fissure-plane, under follow-up big gun hole detonation, can increase the length of rock crackle forming further, will
Rock crushing in the range of vallecular cavity, and throwing goes out vallecular cavity.
Compared with prior art, the invention have the advantage that
The present invention arranges the spiral groove of triangle on cylindrical grain, this and equal length and the powder column of diameter
Compare and can save explosive, it is possible to significantly improve the rock breaking capacity of powder column；The present invention is according to " first cut and draw afterwards "
Explosion thought, powder column explosion time, on powder column, the rock of the spiral groove of triangle is at cumulative detonation metal stream
Effect is lower produces many crackles, and forms fissure-plane in the spiral grooved area of triangle, then at follow-up big gun
Under the detonation of hole, detonation wave can strengthen the broken of keyhole surrounding rock, by rock crushing in the range of vallecular cavity,
And throwing goes out vallecular cavity, this can improve Cut Blasting effect, and improves cyclic advance to a certain extent.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawings with specific embodiment party
The present invention is described in further detail by formula:
A kind of spiral energy collecting type slotting powder column housing, including top pressure closure (1), powder column body (2), seals bottom
(3) three major parts, described below " up and down " refers to the position relationship in Figure of description；
Described top pressure closure (1) is concave plastic closure, and inner lid has two tower grooves, outer wall
On have two tower projections, bottom is hemispherical, directly covers on powder column body (2) top；
Described powder column body (2) is cylindrical empty cavity rod body, for PVC material, triangle spiral shell is distributed on the body of rod
Rotating groove (4), channel section is shaped as triangle, and the shank diameter containing the spiral groove of triangle is less than
Without the diameter of groove, powder column body (2) upper end inwall there are two tower grooves, it is simple to sealing pushed up
Lid (1) is connected to powder column body (2) upper end, it addition, have two diametrically on powder column body (2) top
Circular port (5), bottom inwall is female thread, it is simple to will seal bottom (3) be connected to powder column body (2)
Bottom；
It is provided with metal energy gathering cap (6) housing of same shape in described spiral groove (4), is close to spiral
On formula groove (4) wall；
Described sealing bottom (3), outer wall has two tower projections, and bottom is hemispherical, seals bottom (3)
Top is external screw thread, seals and is attached by screw thread between bottom (3) and powder column body (2).
In conjunction with accompanying drawing, the work process of the present invention is illustrated:
As it is shown in figure 1, sealing bottom (3) top is external screw thread, powder column body (2) lower inner wall is female thread,
After both being tightened, main charge and priming can be sequentially loaded into inside powder column, the most as required, if this medicine
Post not as big gun head, then can directly cover top pressure closure (1)；If this powder column is as big gun head, then need at powder column
Top priming is inserted into the detonator of band payment to a porter, and holes at top pressure closure (1) bottom portion of groove, it is simple to detonator
Payment to a porter passes, and covers top pressure closure (1) after being placed by detonator again；Now on top pressure closure (1) outer wall
Article two, in tower two the tower grooves protruded out in powder column body (2) upper inside wall, realize sealing with this
Top cover (1) and powder column body (2) connection between the two；
A kind of spiral energy collecting type slotting powder column housing processing and fabricating of the present invention is the most simple and convenient, and by specification is attached
Processing and fabricating shown in figure, when to use multiple powder column to be connected, can join end to end powder column,
Now powder column seals two of bottom (3) outer wall tower to protrude out into two of top pressure closure (1) inwall tower
In groove, can realize quickly connecting between two powder columns；
Two, powder column body (2) top circular port (5) diametrically is sequentially passed through with the steel wire of a some strength,
Be possible to prevent powder column to drop out, then the present invention can use in the keyhole tilted upward.
