Description
The present invention relates to mining industry, more accurate theory belongs to the generating means of directive force.
The present invention is used for washing out huge blocks of natural stone along the eyelet of embarking on journey, and destroys the basis of aging blocks room and other building, may be the most effective.
The device of the generation directive force of making according to the present invention, the softening top of going up that is difficult to avalanche in the time of can being used for deep-well exploitation bedded deposit can also be used to forcing to eliminate the poison gas in the coal seam, and the stress-strain state that is used for studying rock area under the natural conditions.
The present invention also can be used for machine building industry, can be used as the load transfer device of the high-power little gabarite of robot, forcing press, lifting gear and cutter, and the miscellaneous equipment that needs to produce huge directive force.
Known a kind of device that destroys large-sized object, i.e. directional force-generating device (SU, A, 1033819), this device contain the tubulose confined chamber that useful elastomeric material is made, and are communicated with the medium source that flows under pressure with it.
In the cavity of tubulose confined chamber, the straight-bar of rigidity is housed along its vertical geometrical axis, this bar is made into the heart portion through hole with tubulose, and the two ends of bar make the connection tube head, connects by first tubulose closed chamber of this tube connector and the medium source that flows under pressure.
The end of tubulose sealing chamber is fixed on the rigidity outer ring hermetically, meanwhile, an above-described connection tube head is housed in each outer ring.
Each outer ring is a sleeve that has internal thread, and this internal thread is meshed with the external screw thread that is connected tube head; Like this, utilize the rigidity straight-bar to be rigidly connected to each other between all outer rings.
The generating means of known a kind of directive force, this device has a housing, and the tubulose sealing chamber is loaded in the housing, and is equipped with two jaws along the longitudinal axis that housing and tubulose sealing chamber geometrical axis coincide.
Jaw is to be used for directly producing the pressed sheet that rises brokenly and act on to each rocks or the object that will destroy.
Vertical geometrical axis of the relative tubulose sealing chamber of pressed sheet is symmetrical distribution.Each pressed sheet is adjacent to the external surface of tubulose sealing chamber with the mid portion of its inner surface, and two tapered planes that launch to both sides in obtuse angle from its middle body are arranged on the inner surface of pressed sheet.
Have a kind of pressed sheet to be compressed the utensil of tubulose sealing chamber, it is a wide annulus made from elastomeric material that is contained in the ring-shaped groove of pressed sheet middle part.
The generating means of known directive force contains the wedge shape insert plate that tubular relatively inner tube of a tyre geometrical axis is symmetrical distribution.
Each wedge shape insert plate has one to be adjacent to the tubulose sealing chamber, and the surface that does not contact with pressed sheet, and two mutual side planes in obtuse angle of tapered plane that are adjacent to pressed sheet are arranged.
The wedge shape insert plate is used for to the pressed sheet transmission being used in addition on these surface section the tubulose sealing chamber being sealed by the power that the tubulose sealing chamber is taken place on its all surface section that do not contact with pressed sheet.
Known this device is not used widely, and its reason is that the pressure that medium produced that flows in the tubulose sealing chamber is limited, generally be no more than 100 MPas, thereby the directive force that acts on the borehole wall is also limited.This situation is soluble as follows, will produce huge axial load in the rigidity straight-bar because flow media acts on the pressure of rigidity straight-bar end and end, outer ring rigidly connected with it, and this axial load is with stretching rigidity straight-bar.This just causes the gap occurring between cycle surface respect to one another and the pressed sheet end face.Very high at pressure, for example under the situation greater than 100 MPas, be difficult to this gap is sealed, thereby material meeting this gap of " bleeding " in the tubulose sealing chamber.Elongating under the quite big situation of rigidity straight-bar, in order to prevent that the material in the tubulose sealing chamber from spilling, must not increase the straight-bar producing cost, that is under the situation of the material replacement rigidity straight-bar material preferable or rare, increase the rigidity of this straight-bar without quality.
Improve the restriction that its rigidity will be subjected to tubulose sealing chamber size with the method that increases rigidity straight-bar diameter, and this size is determined by the wall thickness and the overall size of existing directional force-generating device in its cross section of tubulose sealing chamber also.
Do not change the wall thickness and the overall size of existing directional force-generating device in its cross section of tubulose sealing chamber, increase the cavity size of tubulose sealing chamber, will reduce the amount of movement of wedge shape embedded block and pressed sheet.
When reducing the thickness that the wedge shape embedded block measures in perpendicular to rigidity straight-bar geometrical axis plane, attempt to keep the amount of movement of pressed sheet can significantly increase the contact force that affacts the wedge shape embedded block side of being close to the pressed sheet inclined-plane.This can cause the side surface of extruding wedge shape embedded block, thereby will limit the pressure of flow media in the tubulose sealing chamber.
In addition, the size of rigidity straight-bar cross section, will because of vertical cavity is arranged in the straight-bar and on its sidewall perforation reduce, this eyelet is necessary, because this straight-bar also is used for to tubulose sealing chamber supply flow moving medium.
Basic task of the present invention is to improve directional force-generating device, want the rigidity straight-bar in the improved device and the mutual alignment of all parts to make like this and to arrange, make it possible to improve the rigidity of straight-bar, simultaneously can increase the amount of movement of pressed sheet, and finally can guarantee to produce huge directive force.
This task that is proposed is to solve like this, in directional force-generating device, has a tubulose sealing chamber of making of elastomeric material at least, this sealing chamber can be used to be communicated with the medium source that flows under pressure, it is fixed on each other on the rigidity outer ring that is connected with rigid bar sealed at both endsly, and rigid bar contacts with the tubulose sealing chamber; In directional force-generating device, also have two relative stiffness rod member geometrical axis to be the pressed sheet of symmetrical distribution at least, each pressed sheet is close to the external surface of tubulose sealing chamber with the middle body of its inner surface, and inner surface is two tapered planes that launch to both sides in obtuse angle from middle body; Also have relative tubulose sealing chamber geometrical axis to be the wedge shape embedded block of symmetrical distribution in the directional force-generating device, each wedge shape embedded block has a surface that is adjacent to the tubulose sealing chamber that does not contact with pressed sheet, and have two to be the side plane that acute angle distributes each other, one of them is close to a tapered plane of corresponding pressed sheet; Also has the utensil that pressed sheet is compacted to the tubulose sealing chamber simultaneously, according to the present invention, this device has even number tubulose sealing chamber, and the rigidity straight-bar will be installed between all tubulose sealing chambers, and make the tubulose sealing chamber in couples relatively the geometrical axis of this rigid bar be symmetrical distribution; Simultaneously on the rigidity straight-bar, to make the tapered plane that is adjacent to wedge shape embedded block another side, the wedge shape embedded block will realize with the surface that is adjacent to the tubulose sealing chamber with contacting of tubulose sealing chamber, and relatively tubulose sealing chamber geometrical axis be symmetric arrangement all pressed sheets just in time facing to each surface of the contacted rigidity straight-bar of tubulose sealing chamber external surface.
The directional force-generating device of Zhi Zuoing by means of the increase of straight-bar cross-sectional area, can guarantee to improve the rigidity of rigidity straight-bar like this.Because the rigidity straight-bar is placed between all tubulose sealing chambers, this situation is possible.
Arrange that like this rigidity straight-bar can utilize the area of whole directional force-generating device cross section fully, and not occupied by tubulose sealing chamber, pressed sheet and wedge shape embedded block, can not be the cross-sectional area of the size restrictions straight-bar of tubulose sealing chamber cavity simultaneously.
In addition, the rigidity straight-bar is placed between all tubulose sealing chambers, can make this straight-bar solidly, so also can improve the rigidity of rigidity straight-bar.
The increase of rigidity straight-bar rigidity can significantly improve the pressure of flow media in the tubulose sealing chamber, thereby also can improve the power that is produced by the directional force-generating device pressed sheet.
On the side of rigidity straight-bar, be provided with the inclined-plane, can improve the amount of movement of pressed sheet greatly.This situation has at the rigidity straight-bar under the situation of above-mentioned shape can realize like this that the moving direction of wedge shape embedded block has the possibility that is not orthogonal to the pressed sheet moving direction, but is an angle with this direction, can guarantee to increase the amount of movement of pressed sheet like this.
This situation also may significantly enlarge the scope of application of directional force-generating device, and can improve its operation characteristic greatly.
For example, when destroying the natural rock of bulk, not only need between eyelet, form the crack, and need guarantee to expand this crack along whole parting surface in the deep, ground from ground.Meanwhile, the pressed sheet amount of movement of directional force-generating device is big more, under the identical situation of the dark vertically rice of eyelet number, can obtain the area of bigger parting surface more, will place the device of the generation directive force of being recommended in eyelet.
A pair of tubulose sealing chamber is used in suggestion, and the rigidity straight-bar is made knockdown with the rectangular bar with rectangular cross section and two elements that surround rectangular bar, the end of rectangular bar is fixed on the rigidity outer ring, use perpendicular to one side long on the cross section on the plane of being drawn and determine the orientation by tubulose sealing chamber geometrical axis, the element of two above-mentioned rectangular bars of encirclement will be mounted to along the long one side of rectangular bar cross section has mobile possibility, and utilize flexible member to be connected, and the tapered plane that is adjacent to the rigidity straight-bar of wedge shape embedded block side plane is produced on the element already pointed out with rectangular bar.
The rigidity straight-bar is made into this structural shape, can guarantee the reliable reposition of wedge shape embedded block of stretching out when pressed sheet moves.Particular importance when this point disposes little acute angle at the side plane of wedge shape embedded block, this situation often is necessary for producing huge directive force.Have at the wedge shape embedded block under the situation of so little acute angle because wedge shape embedded block side surface and and its pressed sheet tapered plane that is adjacent between have very big frictional force, when pressed sheet was realized return, the wedge shape embedded block was difficult to reposition.
Also suggestion simultaneously, above-mentioned each surround on the element of rectangular bar and will install a pressure head at least, this pressure head will be positioned on the external surface of the above element along the symmetrical plane that passes between the tubulose sealing chamber.
The existence of pressure head can reduce energy consumption significantly, is promptly destroying the bulk object, for example, when forming splitting plane in the rock area, can reduce the pressure of flow media.The realization of this situation depends on the power that pressed sheet produced of the directional force-generating device that utilization recommends, in splitting plane, set up simultaneously tensile stress, and form additional damage stress in tensile stress area, this stress has local stress concentration in the place of utilization pressure head.
Utilize pressure head can also significantly improve the quality of splitting plane, this is that therefore, by means of the symmetrical distribution of pressure head, splitting plane will pass the axis of eyelet exactly owing to utilize pressure head will " provide " initial point of splitting plane at the outer rim place of eyelet.
In addition, because pressure head is arranged, can utilize the parameter of directional force-generating device decision rock area stress state more accurately, this will rely on remarkable reduction that the influence of rock area intensity parameter is realized.
So, under the situation that the directional force-generating device of making according to the present invention is little in its gabarite and weight is lighter, can guarantee to produce very big directive force.
The directional force-generating device of being recommended is used very extensive, and very convenient in utilization.
