Below in conjunction with accompanying drawing, the utility model is described in further detail:
As accompanying drawing 1, Fig. 2, Fig. 3, shown in Fig. 4, this drill stem hoisting device, comprise hydraulic cylinder main frame and channel-section steel deck, described hydraulic cylinder main frame comprises hydraulic cylinder 1, fixed pulley group 3 is equipped with by hinge 2 in described hydraulic cylinder 1 upper end, hydraulic cylinder piston rod 8 upper end is provided with running block 5 by T-shape frame 7, hydraulic cylinder lower end lock 10 is connected by oil inlet pipe 9 with rod end chamber oil-in, hydraulic cylinder lock 10 is provided with hydraulic control one-way valve 13, below hydraulic cylinder lock, plunger shaft oil-in is provided with one-way throttle valve 12, plunger shaft oil return flow can be controlled by regulating one-way throttle valve, the highest retraction speed of limited piston bar, and then control the maximum lowering velocity of suspension hook, high-pressure rubber pipe 11 is all connected below rod end chamber oil-in and one-way throttle valve below hydraulic cylinder lock 10, as shown in Fig. 5, Fig. 6, Fig. 7, Fig. 8, described channel-section steel deck comprises channel-section steel deck main body 16, channel-section steel deck main body 16 back side is provided with several derrick panel buckles 17, and channel-section steel deck main body 16 front upper, middle part, bottom are welded with righting otic placode 19, dead line otic placode 18, ear plate base 14 respectively, described righting otic placode 19, dead line otic placode 18 are provided with hydraulic cylinder buckle 20 above, righting otic placode 19 bilateral symmetry is welded with oval wire rope handling pipe 21, dead line otic placode 18 bilateral symmetry is welded with spring base 24, dead line pull bar 23 is installed with in spring base 24, described dead line pull bar 23 upper end is welded with " U " type draw ring 22, in order to fixing wire rope, the outer surface cover of spring base 24 has buffer spring 25, and buffer spring 25 lower end is against on the spring compressor 26 of dead line pull bar, be welded with connecting rod 15 between dead line otic placode 18, ear plate base 14, this connecting rod ensure that dead line otic placode does not upwarp after stressed, indeformable, described hydraulic cylinder main frame is contained on channel-section steel deck by hydraulic cylinder buckle 20, and hydraulic cylinder main frame bottom is worn pin and is fixed on ear plate base 14, described fixed pulley group 3 and running block 5 are axially mutually vertical, adopt interior extrapolation method wire rope handling, to improve the stability of piston rod between fixed pulley group, running block.Be equipped with anti-springboard 4 between described fixed pulley group 3, prevent winch fast line from jumping between fixed pulley group and the wire rope of dead line pull bar upper end is jumped out between fixed pulley group; Be fixed with 3 anti-pogo sticks 6 outside described running block 5, prevent other rope on derrick from jumping into the groove skipping of steel rope while between running block and between train.Described wire rope dead line end is fixed on the dead line pull bar of channel-section steel deck, and the pulley of uphanging that live line end walks around drilling derrick is provided with suspension hook.
This drill stem hoisting device is owing to adopting said structure, entirety is fixed on many crossbeams of drilling derrick back side eminence by derrick panel buckle, when piston rod stretches, running block moves together in company with piston rod, forming n × n(n between fixed and moving assembly pulley is even number) train group, be wound around 2 × n strand steel wire rope between train group, namely piston rod often stretches out or retracts 1 meter, namely the suspension hook being then installed on wire rope live line end hoists or transfers 2 × n rice, realizes lifting with this, transfers weight operation.Because dead line end exceeds the some rice of drilling floor surface, rely on the some meters of wire rope and suspension hook deadweight that have more in derrick, can naturally strain this wire rope rope, realize between train, not piling rope, job-hopping.Transfer in weight process, suddenly after brake, the impact kinetic energy that weight inertia produces then is absorbed by buffer spring by wire rope, dead line pull bar, spring compressor, realizes steadily braking.Because this drill stem hoisting device adopts as above technical scheme, efficiently solve wire rope in background technology and arrange uneven problem, the winding of wire rope need not be observed in operation process, so hydraulic operation case can move forward on front side of rig floor, be more conducive to operating personnel and observe place situation, hang, to put operation safer.
As shown in Figure 9, this drill stem hoisting device utilizes the existing Hydraulic Station of drilling crew and with the supporting hydraulic operation case of drill stem hoisting device, provides oil pressure and control to it.Its hydraulic control system of described hydraulic cylinder is connected in existing rig fluid path, hydraulic cylinder and existing hydraulic control equipment concurrently-acting, meets and produces actual needs; Its hydraulic control system of described hydraulic cylinder is positioned at existing rig hydraulic operation platform and liquid gas tong upstream, to reduce the impact on existing rig hydraulic control equipment.
Start Hydraulic Station, above push away hand-operated direction valve handle, the oil-feed of hydraulic cylinder piston chamber, promotion piston rod and running block stretch out, sling suspension hook and weight.Handle returns meta or stops Hydraulic Station, and hydraulic control one-way valve is closed automatically, and trap plunger shaft inner fluid, realize brake.Drop-down hand-operated direction valve handle, the oil-feed of hydraulic cylinder piston rod chamber, and open hydraulic control one-way valve, plunger shaft fluid is discharged by hydraulic control one-way valve and one-way throttle valve, piston rod and running block are retracted, and transfer suspension hook and weight, can control plunger shaft oil return flow by regulating one-way throttle valve, the highest retraction speed of limited piston bar, and then the maximum lowering velocity controlling suspension hook.By on push away or drop-down handle angle different, control to enter hydraulic cylinder fluid uninterrupted, and then hydraulic control cylinder piston rod stretches out or retraction speed, realizes controlling suspension hook flexibly and sling or lowering velocity.Transferring in weight process, suddenly after brake, the impact kinetic energy that weight inertia produces then is absorbed by buffer spring by wire rope, dead line pull bar, spring compressor, realizes steadily braking.
This drill stem hoisting device utilizes the plunger shaft oil-feed of hydraulic cylinder to mention weight, rod end chamber oil-feed is utilized to transfer weight, because piston rod side effective area is less than piston side effective area, so under Hydraulic Station same displacement, lowering velocity, faster than lifting speed, is more suitable for the operation needs such as drilling well setting of casing, breaking down.
This drill stem hoisting device is arranged on the crossbeam of the derrick back side by channel-section steel deck, do not change original derrick geometry, mainly stressed between hydraulic cylinder and piston rod, derrick only bears drill stem hoisting device deadweight (downwards) and the weight (upwards) of lifted weight, does not affect the overall structure of derrick, force analysis.
