1-9 is described in detail the utility model below in conjunction with accompanying drawing:
Form by upper shell 3, housing 9, lower house 13, box cupling 14, back-up block 6, upper shell 3, housing 9, lower house 13, box cupling 14 are coupled to each other successively, plug 1 in the oil conservator is housed in the upper shell 3, is with oil conservator piston 2 on the plug 1 in the oil conservator, and 3 of upper shells form annular oil cavity; Driving shaft 5 is housed in the housing 9, and driving shaft 5 lower end hitch ball pawls 7 are with back-moving spring 8 on the ball pawl 7, and ball pawl 7 front ends are made of the steel bar of axially spaced-apart; Sleeve 11 and ball bag 12 are housed in the lower house 13; Be furnished with continuously uniformly axial " Z " shape chute 10 on driving shaft 5 fore end outer circumference, the drive pin 17 on the housing 9 places chute 10; The different groove of radius is arranged on driving shaft 5 excircles, the back-up block 6 that can move radially is arranged on the housing 9, back-up block 6 and contact grooves are done radial motion with driving shaft 5 rotations.
Drive pin 17 ends on the housing 9 are equipped with spring 16, and spring 16 nut 15 that is fixed is fixed in the hole.
The sealing of ball bag 12 inner cores of lower house 13 inner chambers, with between the sleeve 13 with helping plate to be connected.
Plug 1 communicates with axial " Z " shape chute 10 and the excircle upper groove of driving shaft 5 by oil duct 4 with the annular oil cavity of 3 formation of upper shell in the oil conservator, oil conservator is interior fill in 1 and 2 in oil conservator piston sealing ring B is housed.
There is the sudden change of step " Z " shape slideway 10 bottoms of driving shaft 5 along the vertical axial direction, have the sloping platform rank to change drive pin 17 unidirectional slip in slideway 10 in the time of making driving shaft 5 make reciprocal axial motion along oblique direction.
The spacer pin 18 that is installed on the housing 9 is stuck in the groove of back-up block 6.
As Fig. 1,2, driving shaft 5 and ball pawl 7 are to be threaded, when the aboveground steel ball of abandonning certain diameter during, stay steel ball throttling in the ball pawl and produce that mud pressure promotes driving shaft and the ball pawl moves down, when ball pawl front end moves down into sleeve 11 places as control signal, be subjected to steel ball pressure, ball pawl 7 front ends open, and steel ball is fallen into ball bag 12, and at this moment throttle disappears, mud pressure to driving shaft 5 reduces, and the back-moving spring 8 outside the ball pawl 7 and the upper limit shoulder of housing 9 impel driving shaft 5 returns.
As Fig. 5,6, driving shaft 5 is installed in the inner chamber of housing, on driving shaft 5 fore end outer circumference faces, arranging continuously uniform " Z " shape chute, the drive pin 17 that is fixed on the housing matches with " Z " shape chute, when driving shaft 5 moves down under signal switching mechanism effect, be subjected to the restriction of drive pin 17, the screw that driving shaft 5 is done with respect to the drilling rod axle center, when resetting under back-moving spring 8 effects, driving shaft 5 is made axial linear movement, ball of every throwing, driving shaft 5 rotations 40 degree, " Z " shape chute radially also changes, and can not return former road when having limited driving shaft 5 motions, has guaranteed the reliability of motion.
As Fig. 4,7,8,9, on driving shaft 5 excircles, also have 5 sections identical at interval radius differences, along the axial straight trough that circumference is arranged in order, two sections continuous grooves same angle that staggers successively, back one section groove can be regarded the last period as and rotate same angle around drill rod axis; Corresponding, also there is axle to show off 5 sections identical at interval back-up block groups on the housing of executing agency, three back-up blocks 6 have circumferentially evenly been arranged on each section edge, one section three back-up block also can regarding the last period as in back are around having rotated same angle around the drilling rod axle center, in the time of can guaranteeing the stabilizer reducing like this, back-up block 6 is stressed more even, ball of every throwing, driving shaft 5 rotations 40 degree, different with the driving shaft 5 axial notch radius limits that back-up block 6 matches, so back-up block then stretches out or withdraws, reach the purpose of reducing, 3 ball one-periods of every throwing that is to say that this utility model can change different radiuses 3 times.
When driving shaft 5 moved, at Z-shaped chute inner engine oil also movement therewith, oil conservator piston 2 can move around along cover 1 in the oil conservator, with the balance that keep-ups pressure.
