Description
Technical field
This utility model relates to drilling tool technical field, is specifically related to shackle device on a kind of one-piece drill bit.
Background technology
In Process of Oil Well Drilling, due to bit damage or drilling technology requirement etc., a bite well needs to pull out of hole and changes green bit more than 20 time, and special well or deep-well, a bite well is accomplished by more bit change more than 100 time.Existing replacing green bit generally has two kinds of operating types: one is with on turntable surface by upright for green bit, after drawing button by rotation drill collar, puts into drill bit box and links closely；Two is that three people stand on turntable surface, lifts green bit and drill bit pin thread screw thread is put into drill collar box bore hole, turn-take around drill collar counterclockwise, puts into drill bit box and link closely after drill bit pin thread is introduced drill collar box.Two kinds of operating types there is problems in that former is transferred drill collar distance and should not be controlled, and easily kills drill bit, and upper button difficulty is big, and fragile drill teeth or cutting edge during upper button, cause the destruction in advance of drill bit simultaneously；Latter operating type, three people lift button, coordinate bad or force distribution is uneven, easily cause thread alternating, and worker's labor intensity is big, it is long to draw the button time, and brill card is wet and slippery, and operating personnel rotates and easily slips, and makes drill bit drop, causes bit damage and personal injury.Simultaneously in two kinds of operating types when linking closely, need according to bit size model, frequently change drill bit box, labor intensity is big, wastes time and energy.
In order to solve the problems referred to above, generally use drill bit unscrewing device when shackle, carry out shackle, use drill bit to draw button device and carry out drawing button.But on the one hand tradition shackle its to join a unscrewing device respectively for the drill bit of each size, not only occupy rig floor much room, add the bearing load of rig substructure, and cause the waste of resource.In order to solve this problem, people are the most gradually devoted to research and develop the unscrewing device that can use for sizes drill bit, as Chinese patent 200620168528.0 discloses a kind of drill bit unscrewing device, this unscrewing device includes the square plate being provided with square opening in the middle of, drill bit box is placed in square opening, the middle part of drill bit box is provided with the half slot of three circular arc lobe compositions, when needs replacing carries out shackle operation for various sizes of drill bit, it is only necessary to change drill bit box.On the other hand, people study also for the performance drawing button device, overcome tradition to draw the button device tooth to drill bit and the damage of cutting edge.Button device is drawn as Chinese patent CN104908000A discloses a kind of drill bit.
But above-mentioned unscrewing device and draw button device the most all can be single realize shackle function or draw button function, can not comprehensively realize shackle and draw button function, in order to solve this problem, people the most gradually recognize and research and develop a kind of device combining shackle and drawing button function, as Chinese patent 201320217982.0 discloses a kind of spinner, it is by drill bit box, base, spring, bearing, rubber cushions etc. form, though drill bit can be used for draw button, can be used for drill bit unscrewing, but this spinner is to utilize the baffle plate of the interior single direction arranged of drill bit box to drive the wing of drill bit to rotate, so wing can receive extruding force in a single direction, easily cause the damage of wing, and independent spring supports, the easy deflection of large scale drill bit lays shakiness.
Summary of the invention
In order to overcome the defect of prior art; the purpose of this utility model is to provide shackle device on a kind of one-piece drill bit; integrate draw button, link closely, the function such as shackle, draw button, shackle is easy to operate, it is firm to lay, protection drill teeth and cutting edge, adapted drill bit is many, safety good.
