3) coaxially with slip spider (5-2), support semi-ring (4-5), semi-ring connected in star (4-6) and the center of circle for being oriented to semi-ring (5-7)
On the central axis of slip spider (5-2), so as to concentric with drilling rod.
7. suspension type underground drill rig shackle device as claimed in claim 2, which is characterized in that the hydraulic control unit (8)
Including hydraulic oil source (8-1), multi-way valve (8-2), pilot operated directional control valve (8-3) and sequence valve (8-4), the multi-way valve (8-2) point
It is not connected to hydraulic oil source (8-1) and gyrator, wherein control oil circuit and liquid controlled reversing are drawn in two circuits of connection gyrator
The connection of valve (8-3) control mouth；The pilot operated directional control valve (8-3) be separately connected hydraulic oil source (8-1), clamping cylinder (5-1) and
It revolves push oil cylinder (3).
8. suspension type underground drill rig shackle device as claimed in claim 7, which is characterized in that the pilot operated directional control valve is pushed away with rotation
Oil cylinder is additionally provided with sequence valve between (3).
9. suspension type underground drill rig shackle device as claimed in claim 8, which is characterized in that the clamping cylinder (5-1) and
Rotation push oil cylinder (3) rod chamber is equipped with reset spring, and to guarantee when gyrator does not work, clamping cylinder (5-1) retracts automatically,
Drilling rod is unclamped, rotation push oil cylinder (3) automatically resets；When preventing system oil return back pressure larger, since rodless cavity is poor with rod chamber area
And lead to clamping cylinder (5-1) and rotation push oil cylinder (3) malfunction.
10. the working method of suspension type underground drill rig shackle device, feature described in claim 1 to 9 any claim
It is, comprising the following steps:
The course of work of hydraulic control unit: hydraulic oil source provides high pressure oil, and when pushing multi-way valve to be in the next, gyrator is just
Turn, pilot operated directional control valve work in it is upper, clamping cylinder retract unclamp drilling rod, rotation push oil cylinder be in retracted mode；Multi-way valve is in
When upper, gyrator reversion, pilot operated directional control valve works in bottom, and clamping cylinder, which stretches out, clamps drilling rod, when clamping force order of arrival
When valve sets pressure, sequence valve is opened, and rotation push oil cylinder pushes shackle device rotation, dismantles screw thread；Gyrator dismantles screw thread stopping
After rotation, pilot operated directional control valve works in middle position, and under action of reset spring, clamping cylinder, which retracts, unclamps drilling rod, rotation push oil cylinder contracting
It returns；Hydraulic control unit turns round the clamping of logic control suspension type screw-off mechanism and shackle according to gyrator, easy to operate efficient；
Installation process: being changed to suspension catcher for slotted nut above clamper rear end first, and clamper slips is changed to long card
Watt, gyrator is then retreated, suspension type screw-off mechanism is hung on the screw rod of clamper, finally connected hydraulic by slot milling
Pipeline；
Shackle process: the seam between the drilling rod of the front and back that will be dismantled two is placed between clamper and suspension type screw-off mechanism
Gap, first clamper push long slips to clamp front end drilling rod, then drive gyrator reversion, rotation oil is together with control oil circuit
Pressure rise after reaching liquid controlled reversing valve opening pressure, makes pilot operated directional control valve work in bottom, and clamping cylinder pushes slips to clamp
Rear end drilling rod, when clamping force order of arrival valve sets pressure, sequence valve is opened, and rotation push oil cylinder elongation pushes clamping unit rotation
Turn, loosens drilling rod thread；
Reseting procedure: after loosening drilling rod, the reversal pressure of gyrator is reduced, and control oil circuit pressure is reduced to pilot operated directional control valve to open
Under pressure, pilot operated directional control valve works in middle position, and the clamping cylinder in clamping unit unclamps, and rotation push oil cylinder retracts, and drives suspension
Formula screw-off mechanism returns to original position, and gyrator continues to invert, and dismantles remaining screw thread, completes the disassembly between two drilling rods in front and back.
