When turnbuckle clamp 14 clamps target part (such as beam hanger, oil pipe), P mouthfuls of oil inlet is after the decompression of pressure reducing valve 8, by list
Fliud flushing is carried out to accumulator 5 to valve 7, after pressure reaches oil pressure relief, fluid is overflowed from overflow valve 6, ensures pressure oil on oil circuit
It is always flowing and keeps certain oil pressure；
After spinner starts action, the first hydraulic control one-way valve 9 is opened under the high pressure oil effect of spinner oil circuit, accumulator 5
End pressure oil is connected with the rodless cavity of spinner slave cylinder 4.Since 5 design pressure of accumulator is acted on more than 14 weight of turnbuckle clamp
The pressure of slave cylinder 4, less than the pressure that turnbuckle clamp 14 plus target part (such as beam hanger, oil pipe) weight act on slave cylinder 4,
When spinner driver 15 drives target part to screw, target part drives 14 downlink of turnbuckle clamp, and slave cylinder 4 compresses, rodless cavity
Fluid is overflowed by overflow valve 6；When spinner driver 15 drives target part to unscrew, target part drives 14 uplink of turnbuckle clamp, with
Dynamic oil cylinder 4 stretches out, and by rodless cavity repairing of the accumulator 5 to slave cylinder 4, oil compensation pressure is oil pressure relief.Therefore ensure that rising
And during declining slave cylinder 4 rodless cavity pressure it is consistent with 6 pressure of overflow valve, realization lag function and balances well
Drilling tool gravity avoids running unstable, it is impossible to balance drilling tool gravity, arm support 200 move and spinner after vibrate larger etc. ask
Topic.
