Background technology
Working cycle of rotary drilling rig comprises that lower brill-unit head revolves dig-unit head brill-upper-part rotation-unload soil-upper-part rotation-lower the boring of reversing-carry, rotary drilling rig in the past does not mostly have energy-recuperation system, as shown in Figure 1, the drilling rod 15 of rotary drilling rig, drilling bucket 14 are directly connected with master winch device 8 by steel rope, by the retractable rope of master winch device 8 reels, are realized and are carried brill, lower brill.
Carry while boring, driving engine 12 drives main pump 1, and the high pressure oil of main pump 1 output, by pipeline, after change-over valve and balance cock, acts in master winch CD-ROM drive motor, and motor driving reductor, master winch reel rotate, and realize the lifter motion of drilling rod 15, drilling bucket 14.
During lower brill, drilling rod, drilling bucket, under the effect of gravity, fall automatically, and whole gravitional force becomes thermal energy consumption by balance cock throttling and falls.
When master winch is transferred, operated pilot handle 7, the guide oil flowing out from pioneer pump 5 is through pilot handle 7, along transferring the first conduit of side, promoting valve core of main valve 10 moves up, the high pressure oil flowing out from main pump 1, from the valve core of main valve of opening, flow through, arrive master winch and promote motor 3, branch's fluid is opened and is reached balance cock 11, and CD-ROM drive motor and hoisting mechanism rotate under drilling rod, drilling bucket effect, and oil return forms throttling high pressure at balance cock place, weight equalizer is steadily at the uniform velocity transferred, and lowering velocity is along with the increase of main pump delivery quality.Drilling bucket drives hoisting mechanism to be rotated further, and high pressure oil, after balance cock throttling, decompression, returns to fuel tank along pipeline through valve core of main valve 10.In this process, the potential energy of drilling rod and drilling bucket and kinetic energy are all converted into heat energy at balance cock 11.
When master winch rises, operated pilot handle 7, the guide oil flowing out from pioneer pump 5, through pilot handle 7, along the first conduit of upthrow side, promotes valve core of main valve 10 and moves down, the high pressure oil flowing out from main pump 1, from the valve core of main valve of opening, flow through, through the check valve of balance cock, arrive master winch and promote motor 3, CD-ROM drive motor drives hoisting mechanism to rotate, and hoisting mechanism drives steel rope, drilling rod, drilling bucket upward movement.Meanwhile, from master winch, promote the hydraulic oil process pipeline that motor 3 flows out, through valve core of main valve 10, return to fuel tank, the speed of rising depends on the flow of the high pressure oil that main pump 1 flows out.
In going down process, the potential energy of drilling rod and drilling bucket and kinetic energy can be converted into thermal loss completely and fall.For fear of this part thermal loss, at present, recycling scheme mostly adopts and on pipeline, increases hydraulic accumulator and store, or increases motor and be converted to electric energy, by electric capacity, battery etc., stores, while again moving, discharge the energy storing, reach the object that reclaims and utilize.
But this rotary drilling rig master winch system is transferred energy recycling system and is had following defect:
1, because the brill of rotary drilling rig is deeply larger, the time of transferring is long, and while transferring master winch generally without other actions, need the energy that reclaims more and can not transform at once, the capacity of the energy storage that recuperated energy is used or electric capacity, battery is larger.
2, increased energy storing device, large to space requirement, it is large that rig arranges that palpus is done larger adjustment.
When 3, energy storage releases energy, control difficulty larger, electric capacity, battery energy storage fault rate are high, and cost is high.
