The utility model structurally has greatly different from common drilling rod, its structural form is on the basis of common drilling rod driving torque form, size and size constancy, in when work the temporary transient no drilling rod of internal layer is removed, change all identical moment of torsion pipe nipple pipes (except the drilling rod of innermost layer) of except the length difference every size into.Key length in moment of torsion pipe nipple length of tube can be slightly larger than on the former drilling rod, as long as can satisfy required transmitting torque, other form of structure also can.
Fig. 1 also can be considered the schematic diagram that keeps two-layer former drilling rod, and length is two-layer run of steel after the full extension.Because institute's hole depth of meeting is different at ordinary times, the common requirement of drilling rod is stretched out four or five layers of ability and is satisfied boring requirement, so except the outermost layer drilling rod need not transformed, all the other drilling rods all can be made corresponding moment of torsion pipe nipple pipe and be replaced according to hole depth, to satisfy construction requirement.
Its course of work is as follows: former outermost layer drilling rod carries and connects the connection flange and can do the drill rod rack that slides up and down at drilling machine mast and be connected with bolt.When drilling rod was in the top of drilling rod mast, drill bit was in top, aperture, and along with transferring of wire rope, a whole set of drilling rod and the drill bit of the traction of being restricted begin to enter in the hole, and drilling rod slides downwards along the drilling machine mast slideway together with drill rod rack.When boring when more shallow, at the bottom of drilling rod slided also not before the spacing place, the bottom of mast drill bit and arrived the hole along mast, this moment, drilling rod can not slide downwards again, did not more need a whole set of drilling rod expansion just can be crept into.Creep into finish after hoist engine begin to utilize the wire rope elevator that drill bit, drilling rod are upwards promoted, drilling rod and support can upwards lift away from outside the hole along the mast slideway, namely finish an operation cycle.
When boring is darker, drilling rod together with support along sliding into the spacing place of drilling machine mast under the slideway, spacing place is that limit bracket and outermost layer drilling rod stop gliding the outermost layer drilling rod, but this moment, drill bit did not also arrive at the bottom of the hole, all the other drilling rods and drill bit can continue to glide along the outermost layer drill pipe bore under itself action of gravitation together, when sliding into outermost layer drilling rod internal key top under the positioning sliding block on second layer drilling rod top, positioning sliding block will be blocked by outermost layer drilling rod internal key, stops its second layer drilling rod to glide.This moment, drilling rod was two drilling rod joint length, except the outermost layer that can not glide again and second layer drilling rod, remaining other drilling rod can glide in second layer drilling rod hole as continuing the second layer drilling rod under the gravity of itself, until drill bit just can not stretch out downwards at the bottom of arriving the hole again.In the process of stretching out, pallet all the time on the innermost layer drilling rod and along with the innermost layer drilling rod together up and down.After at the bottom of drilling rod carries drill bit to arrive the hole, the unit head on the rig transfers torque on this drilling rod by the external key on the outermost layer drilling rod, and this drilling rod can be delivered to the moment of torsion on the main frame on the second layer drilling rod by the external key of its internal key and second layer drilling rod.The like, until till the dynamic torque on the rig is delivered to drill bit.When creep into complete after, the drilling rod of the hoist engine on the rig by wire rope and elevator pulling innermost layer is to rising.And a section origin-location that shrinks back of drilling rod that stretch out when the innermost layer drilling rod can will be transferred by pallet this moment rises to stem the eminence of drilling machine mast again together with support, makes the drilling rod with drill bit break away from the aperture, is convenient to unload soil.Above process is the one action circulation.
The upper limit position block 103 of the axle shape of having strong market potential of m moment of torsion pipe nipple pipe for dual action axial: 1, play the free bearing anastomosis; 2, stop on the pipe nipple drilling rod and alter, prevent from altering and throw off up and down between rear drill pipe nipple and pipe nipple and can't work, length is advisable with the pipe nipple drill pipe diameter that exceeds ragged edge.
Outside lower limited cap 202 can prevent that the drilling rod of innermost layer lightened drilling rod and innermost layer breaks away from drilling rod and can't transmitting torque, can play the effect of drilling rod location; Two halves shell type limited cover 201 is that symmetry cuts.
Free bearing makes between the innermost layer lightened drilling rod inside and connects convenient disassembly, and utilizes stayed mast 105 or wire rope elevator can be guided to the drilling rod outside, so that install, dismantle.
Can adopt suitable this lightweight energy saving type rotary drill rod of the number of plies according to the drilling depth needs, the course of work in the drilling process and boring effect are identical with common drilling rod.
Effect is showed: rotary drilling rig removes that rig creeps into (unit head drives drilling rod and rotates) and drill bit proposes the aperture and leave to unload beyond the soil at work, and the remaining working time is the rig hoisting or transfers the drilling rod time.Drilling rod according to the hole depth apolegamy is lightweight, plays energy-efficient purpose when transferring therefore can promote at hoist engine.
Take the drilling rod of TR220D rig as example, if hole depth in 39 meters the time, the 4th layer and the 5th layer of drilling rod do not come into operation, and the part that do not come into operation drilling rod weight reaches about 3.5 tons; If hole depth is in 26 meters the time, the 3rd layer, the 4th layer and the 5th layer of drilling rod do not come into operation, and unused portion weight reaches about 5 tons.And now used drilling rod because the restriction of structure, can only be at work with the drilling rod Integral lifting, transfer, cause unnecessary waste.
This technology can be with about 5 tons of former drilling rod weight savings, and hoist engine working time this moment can not be less than 1/3rd of net cycle time.This rig hoisting (decline) speed is about 1.3m/s, the full-time employment time is take 16 hours as (majority did not stop as 24 hours), the elevator working time can not be less than 5.3 hours, and the power that the weight that this moment, drilling rod alleviated is saved at work is: 50000N * 1.3M/S=65000N.M/S=65KW.Check in the high-horsepower diesel engine fuel oil and be generally about 210g/KW.h, so save diesel oil 210g/KW.h * 65KW * 5.3h=72.345Kg every day.If diesel oil is pressed the calculation of price of 8 yuan of per kilograms, save 578 yuan every day.To be on the safe side, the result who calculates is again by 50%, and also can save 289 yuan every day, and this is a considerable expense.
When the degree of depth between 26 meters～39 meters, 3 layers on used drilling rod gets final product, the weight of saving is about 3.5 tons.But hoist engine working time this moment (being that drilling rod promotes, transfers the time) can not be less than 50% of net cycle time, and this moment is because the power that the drilling rod weight reduction is saved is 35000N * 1.3M/S=45.5KW, every day, capable of saving fuel oil weight can reach 210g/kw.h * 45.5KW * 8h=76.44Kg, saved as calculated 611 yuan every day.If by 50% of result of calculation, also can save 305 yuan every day, 1 year by 250 days work Time Calculation, 7.6 ten thousand yuan of minimum savings in a year.More than just to the rough calculation of fuel oil part, also be very considerable to the reduce wear economic benefit of life-extending aspect of main frame, oil pump, motor, particularly hoist engine and the wire rope that brings after the drilling rod weight saving.
