Description
Technical field
It the utility model is related to a kind of device, and in particular to a kind of double-brake surface drive decelerator.
Background technology
After surface drive shutdown, polished rod is because of the torsional-energy stored in sucker rod and the hydraulic motor effect of screw pump
Should, high speed reverse rotation can be produced, if can not effectively be controlled rapidly, danger can be brought to equipment and operating personnel.So will
Surface drive is asked effectively to control polished rod to invert and torsional forces present in sucker rod can be discharged.Existing screw rod
Pump surface drive typically using mechanical click and installs brake ribbon additional to realize the purpose of braking and release.This dress
Brake ribbon easily abrasion or glued is put, needs Artificial Release to give out light bar moment of torsion after shutdown, braking is not safe and reliable enough, very big peace be present
Full hidden danger；The surface drive having at present takes external caliper disc water brake, can discharge polished rod with automatic slowly after shutdown
Moment of torsion.The inevitable hydraulic pump of this device and one-way clutch abrasion, cause brake fade.
Utility model content
The utility model provides a kind of double-brake surface drive decelerator, while being mounted with water brake, adds again
A kind of centrifugal speed control unit is filled；When water brake fails, play a part of controlling polished rod speed reversal, and make light

State on power output shaft, the axle sleeve is provided with the ratchet being arranged symmetrically, and the ratchet coordinates with the ratchet position.
Described double-brake surface drive decelerator, wherein the multifunctional regulating valve includes valve body, check valve, subtracted
Pressure valve, instantaneous parking valve rod and quick release valve rod, the valve body outside is provided with oil inlet one, instantaneously stop oil-out, high pressure
Oil-out and oil return opening；The oil inlet one is communicated by pipeline one with the instantaneous parking oil-out, and the pipeline one is pitched out
Pipeline two communicates with the oil return opening, and the pipeline y-bend goes out pipeline three and communicated with the high-pressure oil outlet；The check valve peace
In the pipeline one, the instantaneous parking valve rod is arranged in the pipeline two, and the quick release valve rod is arranged on institute
The end of pipeline three is stated, the pressure-reducing valve is arranged in the pipeline three.
Described double-brake surface drive decelerator, wherein the oil-out of the oil pump passes through oil pipe one and oil inlet
One connection, high-pressure oil outlet by oil pipe two and instantaneous parking oil-out by oil pipe three connect threeway and with the hydraulic jack
Oil inlet two be connected；The oil return opening is communicated to the fuel tank by oil pipe four；The fuel tank passes through oil pipe five and the oil
The oil inlet three of pump is connected.
Above-mentioned double-brake surface drive decelerator operation principle is as follows：Gear wheel when surface drive runs well
Drive pinion rotation, one-way clutch separation, oily air pump inoperative；After surface drive is shut down, when main shaft inverts with polished rod,
One-way clutch engages, and drives operation of oil pump, hydraulic oil is entered into braking clamp hydraulic jack, braking clamp piston by the road from fuel tank
Stretch out clamping brake disc.Under Multifunction pressure valve action, hydraulic fluid pressure declines, braking clamp releasing of brake disk, and polished rod continues
Reversion, reversion rear pump or output pump work again, hydraulic fluid pressure rise, braking clamp and clamping brake disc, and the brake so discontinuously repeated-
Until the reverse torque of polished rod is zero, reversion stops for release-brake-release ....Multifunctional regulating valve makes in orderly shutdown
Used time, the instantaneous valve rod that stops is normally open, and quick release valve rod is normally off；According to realistic well condition difference and field operation
When needing to improve the rate of release inverted, quick release valve rod is outwarded winding, now hydraulic fluid pressure reduces pressure etc. by pressure-reducing valve
Level, hydraulic fluid pressure are controlled in relatively low scope, can reduce brake weight, accelerate the speed of polished rod reversion release；Work as light
When bar needs stop reverse immediately, instantaneous parking valve rod can be tightened, now hydraulic fluid pressure only has a way valve passageway, brakes
Hydraulic oil in-cylinder pressure is no longer reduced afterwards, and brake disc no longer inverts, and realization is stopped immediately.In centrifugal speed control device, brake
There is centrifugal brake hoof block between body and shell, external end of braking is ratchet, and ratchet is arranged on the axle sleeve coupled with power output shaft
On, when surface drive parking polished rod drives main shaft reversion, ratchet engages with ratchet moment, effective in fluid brake
During work, centrifugal brake hoof block simply rotates with reversion, and no centrifugal action, power output shaft realizes power output with rotation；
If fluid brake fails, when main shaft speed reversal increases, centrifugal brake hoof block is thrown away and shell pressure under the action of the centrifugal force
Huge frictional force is tightly produced, reduces speed reversal；Frictional force reduces after speed reversal reduces, speed reversal increase, centrifugation
Shoe piece throw away not only under the action of the centrifugal force with shell pressing friction power but also increase, promote speed reversal to reduce, so circulation,
The control of polished rod speed reversal is set constantly to reduce in certain limit, until being zero.
The beneficial effects of the utility model are：The utility model is double-inversion control device, farthest be ensure that
Equipment and personal safety.Fluid brake and centrifugal speed control device are automatic release polished rod moment of torsion, securely and reliably.
