Description
The utility model relates to a kind of petroleum perforation charge of beehive-shaped charge and the solid firing mount of this perforating bullet, belongs to the component of petroleum oil perforation gun.
The cumulative petroleum perforation charge is a kind of civilian CUMULATIVE BLASTING powder charge.Perforating bullet has a columniform cup-shaped body, and afterbody has taper, is the plane at the bottom of the bullet, has the groove of propagation of explosion hole and placement detonating fuse on it.Gu firing mount is the bearing support that perforating bullet is installed.Be generally strip, have the extension shell hole on it.During use, perforating bullet is inserted in the extension shell hole one by one, detonating fuse is stuck in the detonating fuse groove of projectile tail, and then the solid firing mount that perforating bullet is installed is inserted in the gun barrel of perforating gun.
Hang in the shell hole for the ease of perforating bullet being packed into and being fixed on, design has the locking device that can cooperatively interact on body middle part and extension shell hole.On a kind of perforating bullet and solid firing mount of public use, adopted " quick plug type " locking device.Specifically this locking device is to constitute like this:
Drive a cannelure at the middle part of body.The latter part of body is made two planes of paralleling to the axis symmetrically, and circular surfaces is tangent at the bottom of making these two planes and cannelure.Make the cross section of body latter part become like this and cut two arc circles.Correspondingly on solid firing mount, hang shell hole and also have and the identical shape of body latter part cross section, and make both become big gap movingly.
Hang when playing, afterbody is inserted facing to hanging shell hole; When treating that cannelure is concordant with solid firing mount, body is rotated about 90 ° of angles vertically.At this moment the circular arc of body latter part partly just in time facing to the bowstring of hanging shell hole partly with the cannelure acting in conjunction, is fixed on body in the extension shell hole.
This design of prior art can make the body axial restraint effectively.At body radially, the bowstring of hanging shell hole is partly tangent with circle at the bottom of the cannelure just, can prevent that body from moving (bowstring that will hang shell hole in the prior art is arranged in the vertical direction of solid firing mount) in that solid firing mount is spacious longitudinally.But, be a bit larger tham the body external diameter owing to hang the maximum diameter of hole of shell hole, and the end circular diameter of cannelure must be less than the external diameter of body in horizontal (with the parallel direction of bowstring of hanging shell hole).Therefore, on this direction, the spacious momentum of body equal at least to hang the shell hole diameter with cannelure at the bottom of circular diameter poor, can reach several millimeter.Since this spacious moving axial in prior art perpendicular to solid firing mount, so be called laterally spacious moving.
This laterally spacious moving meeting causes difficulty for the dress rifle.This is because the internal diameter of perforating gun is to design according to the solid firing mount circumscribed circle after shooting.Gu, when the dress rifle, certainly will be able to not pack into smoothly if each perforating bullet lateral attitude on the firing mount changes greatly.
Laterally spacious moving in order to reduce, prior art adopts flute profile shape material to manufacture solid firing mount, and it is laterally spacious moving that attempt utilizes two sidewalls of flute profile to reduce.But such measure can only be played partly effect.Because when the body first part is positioned within the flute profile, two sidewalls reduce laterally spacious moving purpose by stopping that the body cylindrical plays.And when the afterbody of body is positioned within the flute profile since the body latter part cut two arc, and by the part that cut be in solid firing mount laterally, so two sidewalls can't stop the horizontal spacious of body to move in this case.According to this solution of prior art,, as if should adopt " worker " shape shape material to manufacture solid firing mount if it is laterally spacious moving to desire all eliminations.
But also there is following problem in spacious moving scheme to utilize section bar to reduce laterally, thereby makes the professional believe that this can not be a kind of effective solution.
At first, adopt the shape material of band sidewall to make solid firing mount increase with the material amount, weight is difficult for alleviating.
Secondly, the sidewall of shape material will certainly occupy the space in the gun barrel, and body is reduced, and explosive payload is restricted.
The more important thing is that the existence of sidewall makes solid firing mount inconvenience reverse vertically, thus can't allow the perforating bullet of diverse location install facing to different directions, to realize multi-faceted perforation.In fact, above-mentioned solid firing mount generally only is used for the perforation of 180 ° of mutual deviations.
Task of the present utility model is a kind of new perforating bullet of design and consolidates firing mount accordingly, this new perforating bullet and solid firing mount should keep the advantage that prior art is convenient to hang bullet, also should have as far as possible little horizontal spacious moving simultaneously, and bomb rack can axial torsion, to realize multi-faceted perforation.
The utility model has been realized above-mentioned task by the geometrical property that utilizes inscribed circle.Its solution is: when the shape of shell hole is hung in design, make to be equivalent in the prior art that the part (being called setting circle) of circle is to hang the geometric inscribed circle of shell hole just at the bottom of the cannelure on the body, utilize the geometrical property of inscribed circle to realize the radial location of perforating bullet.
Perforating bullet and solid firing mount thereof according to the above-mentioned requirements design can be described with following essential feature.
A kind of petroleum perforation charge and solid firing mount thereof, perforating bullet has the cylindrical cup-shaped body, and afterbody has taper, has the groove of propagation of explosion hole and placement detonating fuse on the breech face; Gu firing mount is the strip flat board, have the extension shell hole on it; On body and extension shell hole, be provided with " quick plug type " locking device.The new feature that the utility model provides is: the diameter of body latter part promptly has a shaft shoulder at the body middle part less than the diameter of first part; On the surface of the cylindrical (setting circle) of body latter part, radially extend the protrusion that is called as backstop more than, these backstops evenly distribute along circumference, the thickness that is a bit larger tham said solid firing mount sheet material to the distance of the said shaft shoulder, it highly is no more than the height of the shaft shoulder, and root width (being the distance between two intersection points of the outline line of backstop dual-side and setting circle outline line) is significantly less than the location diameter of a circle; On said solid firing mount, the shape of hanging shell hole can be a kind of in triangle or other regular polygons or the circle, and setting circle is the inscribed circle of hanging shell hole just; Along the periphery of hanging shell hole have number, shape and position all with body on the breach that adapts of number, shape and the position of backstop, pass this breach to allow each backstop.
The good result that such designing institute has is tangible.
Because setting circle is the inscribed circle of hanging shell hole just on the body, can know by inference by geometry, the radial position of perforating bullet of the present utility model in hanging shell hole is to determine more, radially spacious momentum is the dimensional tolerance of hole and axle, only just can be effectively with radially spacious moving being controlled within certain scope by the controlling dimension tolerance, this scope is significantly less than the spacious momentum of prior art.
Because the periphery realization radial location that only utilizes setting circle and hang shell hole is Gu firing mount can adopt flat-sheet material to manufacture.Compared with the prior art, the gun barrel space that this can make full use of perforating gun alleviates the weight of solid firing mount, also is convenient to each is hung between the shell hole longitudinally be twisted into certain angle, realizes multi-faceted perforation.
In addition, the utility model has obviously kept the advantage of being convenient to hang bullet in the prior art well.
The utility model comprises ten width of cloth accompanying drawings.Wherein
Fig. 1, Fig. 4 and Fig. 7 are the utility model petroleum perforation charge body lateral views;
Fig. 2, Fig. 5 and Fig. 8 are the perspective views of observing from afterbody;
Fig. 3, Fig. 6 and Fig. 9 be respectively with the machine drawing of the supporting solid firing mount of Fig. 1, Fig. 4 and Fig. 7;
Figure 10 is the sectional view behind the utility model petroleum perforation charge dress rifle, has shown mode of occupation of the present utility model.
Below in conjunction with embodiment and contrast accompanying drawing and describe concrete formation of the present utility model in detail.
Perforating bullet of the present utility model all has a columniform cup-shaped body.Afterbody has taper (11), hangs in the shell hole (2) so that be inserted into.Be the plane at the bottom of the bullet, have the groove (8) of propagation of explosion hole (9) and placement detonating fuse on it.Propagation of explosion hole (9) is communicated with body inner chamber and detonating fuse groove (8).The diameter of body first part (6) forms a shaft shoulder (14) greater than the diameter of latter part (7) in the centre.On the body external surface (7) of latter part, the outer more than one backstop (5) that protrudes of the thickness of slab of (14) solid firing mounts (3) of the above-mentioned shaft shoulder of distance.Backstop quantity as required and processing method different can be designed optimal backstop shape.Among three embodiment that will narrate below, when providing number respectively and be one of backstop, two, three or four, the backstop shape and the corresponding processing method of suitable employing.
Fig. 1, Fig. 4 and the same Fig. 3 of perforating bullet, Fig. 6 and solid firing mount shown in Figure 9 shown in Figure 7 constitute a most preferred embodiment of the present utility model respectively.
What Fig. 1, Fig. 2 and Fig. 3 provided is the embodiment with two backstops.This scheme apart from (14) solid firing mount (3) (see figure 3) thickness of slab places of the shaft shoulder, is protruded two backstops (5) symmetrically on setting circle (7) external surface of body latter part.In this example, backstop has approximate rectangular end surface shape.It highly is no more than body cylindrical (6).From axially, the distance between two intersection points of the outline line of backstop dual-side and setting circle outline line (being the root width) (A) is significantly less than the diameter of setting circle (7).When the backstop number is less than when equaling 2, root width (A) is preferably less than the setting circle diameter
Doubly.Help guaranteeing less horizontal spacious moving like this.In the present embodiment, the root width of backstop is about 1/5 to 1/3 of setting circle diameter.
The extension shell hole (2) of this example is circular (see figure 3).This is a special case of the present utility model, and its setting circle (7) is onesize circle with hanging shell hole (2).Because the existence of fit clearance can be similar to and think that setting circle is inscribed within the extension shell hole.Be evenly distributed with two breach (1) along the circumference of hanging shell hole (2), the backstop on its shape and the body (5) shape matches.Gap position can vertical or horizontally be arranged.No matter how breach is arranged, all should be taken into account the orientation of body location back detonating fuse groove (8) when design.Principle is, the orientation of location back detonating fuse groove (8) and detonating fuse are around to consistent, and backstop (5) is lucky and stagger in breach (1) position.Can utilize fixedly perforating bullet tangential of detonating fuse like this, prevent that body from rotating.This situation can see too clearly in Figure 10.Breach (1) is vertical cloth in this example, correspondingly on the body the direction of detonating fuse groove (8) consistent with the diameter at backstop (5) place.
Hanging per two of shell hole is one group of (see figure 3), hangs between the shell hole for every group to link to each other with dowel (10).When the multi-faceted perforation of needs, dowel (10) is reversed certain angle just can.
For ease of the dress detonating fuse, having gap (4) between per two extension shell holes on the dual-side edge of solid firing mount.Shooting the back detonating fuse arranges around gap (4) and dowel (10).This can make the layout of detonating fuse not occupy the space of thorax in the gun barrel.
Present embodiment is suitable for adopting die casting or injection moulding body.On columniform body, make little approximate rectangular projection because these two kinds of methods are easier.
In addition, if suitably improve setting circle and hang quality of fit between the shell hole, one in two backstops in the last example being removed, only keep one of them, also is feasible.This has constituted the embodiment of a backstop of the utility model.
What Fig. 4, Fig. 5 and Fig. 6 provided is the embodiment that three backstops are arranged.The top shape of its backstop (5) is consistent with body cylindrical shape, and the side of adjacent two backstops links to each other and forms a plane (13), and this plane and setting circle (7) tangent (seeing Fig. 4 and Fig. 5).In fact this scheme is fit to adopt mach similar to the prior art way to make body except that suitable die casting or injection moulding manufacturing more.Different is, after cannelure is driven in the centre of cylindrical body, with the body latter part mill equably three with the tangent plane (13) of setting circle (or at the bottom of the cannelure circle), rather than two.
The extension shell hole (2) of this scheme is an equilateral triangle (see figure 6) basically, and the setting circle on the body (being the end circle of cannelure) is the inscribed circle of this equilateral triangle.For the consideration on the manufacturing process, three angles (12) that hang shell hole are made into the circular arc that matches with body cylindrical (6).
When the triangle of hanging shell hole (2) had a limit (for example base among Fig. 6) perpendicular to solid firing mount (3) axial, the detonating fuse groove (8) on the body just can guarantee to shoot back backstop (5) perpendicular to a side of backstop (5) and stagger with breach (being three angles (12) of equilateral triangle).
Identical with a last embodiment, hanging shell hole also is two one group, has dowel (10) to link to each other between every group, has the gap (4) of detonating fuse on the side of the solid firing mount sheet material between two extension shell holes.
Fig. 7, Fig. 8 and Fig. 9 are the embodiment with four backstops.Except the quantity of backstop is four and to hang shell hole be the square, this scheme and a last scheme are basic identical.The top shape of its four backstops (5) is consistent with body cylindrical shape, and the side of adjacent two backstops is linked to be a plane tangent with setting circle (13) (seeing Fig. 7 and Fig. 8).Processing method also is the same.Behind the processing cannelure, mill out equally distributed four planes in the body latter part in the middle of the body, and make each plane tangent with setting circle (justify at the end that is cannelure) (7).
It is square hanging shell hole (2), its four angles (12) also make with body cylindrical (6) match circular-arc.When two limits being arranged perpendicular to solid firing mount when axial in the four edges of hanging shell hole (2), the detonating fuse groove (8) on the body should be also perpendicular to four with the tangent plane (13) of setting circle (justifying at the bottom of the cannelure) in one.
Although the body processing method of above-mentioned latter two embodiment similar to the prior art, the difference of the utility model and prior art still is tangible.In prior art, the shape of the desired extension shell hole of body latter part shape can not have inscribed circle.The utility model is requirement then, no matter how its shape changes, hanging shell hole must be a kind of geometry with inscribed circle, and the setting circle on the body is this inscribed circle just.
Figure 10 has shown mode of occupation of the present utility model.Wherein 15 is the gun barrel of perforating gun, the 3rd, solid firing mount.Dress is the perforating bullet 16,17,19 and 20 with four backstops on it.The jet direction of perforating bullet 16 goes out paper in the middle of them, and the jet direction of perforating bullet 20 is paper feed faces, the perforating bullet 17 directive left sides, perforating bullet 19 directives the right.Suitably adjust the angle of reversing dowel 10, can realize the perforation of multiple angles.The winding of detonating fuse 19 can see too clearly in Figure 10, and it is to arrange around detonating fuse groove on gap, the body and dowel.
