Description
Technical field
The present invention relates to the big drill bits of anti-trepan to fall to bore processing technology field, and specifically the big drill bit of anti-trepan falls to bore
Method holds basket, falls to bore structure.
Background technique
Anti- well is bored in continuous two hairs of construction or more drilling, after the big drill bit reaming in No.1 hole again by big drill bit
Xia Kou is transferred to, the transshipment problem of big drill bit is solved, prepares to expand No. two holes, is applied with this to mitigate worker's labor intensity and shortening
Between working hour, but during big drill bit is unloaded in reversion afterwards in place for decentralization, drilling rod disconnects from centre, after drilling rod disconnects from centre, remains
Because self weight can tilt, restart drilling machine docking disconnection drilling rod just can not accomplish remaining drilling rod.How being stayed in the borehole after disconnection
Indwelling drilling rod and drill bit be brought up from drilling, and reduce or eliminate security risk present in treatment process, guarantee remaining
Engineering continues to construct, and is urgent problem.
Summary of the invention
The technical problem to be solved by the present invention is to how staying drilling rod in the borehole and drill bit to mention after disconnection from drilling
Come up.
The present invention solves above-mentioned technical problem by the following technical programs:
The anti-big drill bit of trepan falls drill method, comprising the following steps:

2) steel cable is worn holding in basket ring, keep wirerope both sides isometric；
3) drilling machine connects the more drilling rods originally laid down, and holds basket and just arrives drilling rod disconnection position, holds the steel wire blocked on basket
Rope slowly falls on down mouth under ommatidium；
4) big drill bit is fixed to two wirerope of small mouth now under；
5) it makes a stop collar and puts two coir ropes from ommatidium is suitable for reading drilling rod and two steel wire loops in stop collar
Bolt is manually promoted stop collar to the indwelling drilling rod upper end being retained on big drill bit, at two from ommatidium is suitable for reading on stop collar
Under the tension force effect of wirerope, stop collar is taken indwelling drilling rod among ommatidium to, prevents drilling rod from stabbed during upper mention to palisades
It is interior；
6) drilling machine is slowly promoted, and more drilling rods one by one go because drilling machine is promoted by removal, at this moment indwelling drilling rod exposing ommatidium mouth
Journey is limited, and indwelling drilling rod does not reach directly in borer drill rod hole；
7) the indwelling drilling rod exposed connects hand basket cap, and two cucurbits lock hand basket cap by top plate anchor cable lifting point, and two
After cucurbit is energetic, drill power head falls, and holds wirerope on basket and relaxs one's efforts, lays down wirerope；
8) it holds and is locked between basket and hand basket cap with anchor chain connection, two cucurbits are slowly relaxed one's efforts simultaneously, to holding basket and hand basket
Between cap anchor chain hard after, pluck two cucurbits；
9) drilling machine is promoted to after the exposing of drill pipe slip slot, and card upper slips shed and hold basket and hand basket cap, drill power head pair
Connect indwelling drilling rod.
Preferably, in the step 2), wirerope is fixed with ingot card below basket ring holding.
Preferably, in the step 3), two cable wire ends are good big drill chuck with ingot card, and every side ingot card is many
In 3.
The present invention also provides one kind to hold basket, falls drill method applied to the above-mentioned big drill bit of anti-trepan；Holding basket includes
Basket body, is fixed in the bottom of basket body and holds basket ring, and upper end is provided with the external screw thread connecting with drilling rod.
The present invention also provides a kind of anti-big drill bits of trepan to fall to bore structure, including holds basket, wirerope, stop collar；It is described
It holds basket to be fixed on drilling rod, and arrives small mouth now by the way that drilling machine is gradually lower；Holding basket includes holding basket ring, and steel is installed in ring
Cord, two rope end of wirerope are fixed with big drill bit respectively；Indwelling drilling rod is fixed on big drill bit；Stop collar is set in two steel wires
It on rope and indwelling drilling rod, and is mentioned by traction rope to indwelling drilling rod upper end, indwelling drilling rod upper end is made to be in small mouth interposition now
It sets.
The present invention has the advantages that
The use for holding basket plays a key effect in processing accident, solves the problems, such as that wirerope is fixed wherein, keeps away
Exempt from personnel and entered ommatidium processing drilling rod docking problem, greatly improves safety coefficient when processing accident, safety benefit is outstanding
It is considerable.The method is simple and practical, and only with 1 bottom class, just processing terminate in actual operation.
In addition, cooperate the tension of two wirerope using stop collar, indwelling drilling rod can be drawn to my position among ommatidium
It sets, during avoiding indwelling drilling rod from above mentioning in stamp to palisades.
