Description

A kind of well impacter drilling rod fishing device
Technical field
This utility model relates to mechanical design field, particularly relates to a kind of impact device, specifically refers to a kind of well impacter drilling rod fishing device.
Background technology
It is known that drought and water-scarce area is to be badly in need of the hydrology to be carried out, the area of water well drilling, the probing on leakage stratum is also to need substantial amounts of water, and use flushing liquor to drill, creeping into inherently needs water, is necessary for from far local fortune water, not only add drilling cost, and Chang Yin cuts off the water and stops boring.For drought and water-scarce area, multilamellar of holing is missed and area employing air (foam) of the difficulty that supplies water is crept into and can be improved drilling efficiency, reduction cost, shortening construction period.Therefore, in the hydrology, water well drilling, air (foam) creeps into particularly important.It is to purge boring, cooling drill bit using compressed air as circulatory mediator that air (foam) creeps into, and by landwaste, from the tail band of hole and band portals outer drilling method.Air latent drift drilling technology, is a kind of comparative maturity and highly advanced drilling method in China.This method is applicable to dry up completely anhydrous or air-flow of stratum can absorb the stratum of a small amount of current invaded in hole.Air (foam) creeps on the basis of any rotary drilling equipment, abandons original mud recycle unit as long as spelling and changes circulation device for air, it is possible to carries out air drilling.
But, in deep-well is constructed, because punching is too deep, once drilling rod product occurs that quality problems, down-hole hammer, down-the-hold drill bit and drilling rod can drop in well, construction failure occur.If this fault can not solve, well then can be destroyed, and causes huge economic loss.Therefore, fall how well accident solves, become the problem that all rig operator pay close attention to.
Summary of the invention
The technical problems to be solved in the utility model is for the weak point existing for prior art, a kind of well impacter drilling rod fishing device is provided, this device passes through guide sleeve righting, in main body, class bolt die screw thread thread tapping on fracture bar is connected with fracture bar, then propose wellhole, solve problem, change technical pattern simple, easy to use, salvage effective.
Technical solution of the present utility model is, following a kind of well impacter drilling rod fishing device is provided, including main body, described main body is provided with bellmouth, it is provided with tapered thread in described bellmouth, circumferentially being distributed in described tapered thread and axially offer several chip areas, the cone-apex angle of described bellmouth is 10 °.
As preferably, the ridge angle of described tapered thread is 55 °.
As preferably, described chip area is one to have 6, and arranges evenly around axis.
As preferably, being provided with guide sleeve at the bellmouth of described body end, for welding between described guide sleeve and main body, described guide sleeve is cone cylinder shape, and the cone-apex angle of described guide sleeve is 45 °.
As preferably, described main body integral hardness is HRC55 ~ 66.
As preferably, in described main body, the one end away from guide sleeve is provided with tool joint, and described tool joint is provided with dismounting and pulls mouth.
As preferably, described bellmouth runs through main body along central axis.
Using the beneficial effect of the technical program: by guide sleeve righting, in main body, class bolt die screw thread thread tapping on fracture bar is connected with fracture bar, then proposes wellhole, solves problem, changes technical pattern simple, easy to use, salvages effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model well impacter drilling rod fishing device.
Fig. 2 is the left view (guide sleeve is not drawn into) of Fig. 1.
Shown in figure: 1, main body, 2, bellmouth, 3, tapered thread, 4, chip area, 5, guide sleeve, 6, tool joint, 7, dismounting pull mouth.
Detailed description of the invention
For purposes of illustration only, below in conjunction with the accompanying drawings, the well impacter drilling rod fishing device of utility model is elaborated.
nullAs shown in Fig. 1 to Fig. 2,A kind of well impacter drilling rod fishing device,Including main body 1,Described main body 1 is provided with bellmouth 2,It is provided with tapered thread 3 in described bellmouth 2,Circumferentially it is distributed in described tapered thread 3 and axially offers several chip areas 4,The cone-apex angle of described bellmouth 2 is 10 °,The ridge angle of described tapered thread 3 is 55 °,Described chip area 4 is one to have 6,And arrange evenly around axis,It is provided with guide sleeve 5 at the bellmouth 2 of described main body 1 end,For welding between described guide sleeve 5 and main body,Described guide sleeve 5 is cone cylinder shape,The cone-apex angle of described guide sleeve 5 is 45 °,Described main body 1 integral hardness is HRC55 ~ 66,In described main body 1, the one end away from guide sleeve 5 is provided with tool joint 6,Described tool joint 6 is provided with dismounting and pulls mouth 7,Described bellmouth 2 runs through main body 1 along central axis.
Being provided with guide sleeve 5 and tool joint 6 in the main body 1 of impacter drilling rod fishing device, guide sleeve 5 opening cone angle arranges at 45 °, is welded on one with main body 1, operationally for righting drilling rod;Main body endoporus is machined with tapered thread 3, and cone angle is 10 °, 55 ° of form of thread angle, on inside tapered thread, is circumferentially distributed and axially has 6 chip areas 4, forms class bolt die structure, as the chip area 4 of hitch, main body 1 integral hardness HRC55~60;Tool joint process a pair flat, pull mouth 7 as dismounting, the endoporus of tool joint 6 is machined with regular screw threads, is welded as a whole after being connected with main body 1 again.
When salvage is carried out, drilling rod is connected with tool joint, and drive fishing device to rotate, guide sleeve draws just rupture drilling rod or impacter in main body internal thread hole, by advancing and rotating, class bolt die main body can form external screw thread on fracture drilling rod, screws in one with main body, then will fall off thing and take out of outside well, arrive the purpose salvaged.
In the above-described embodiments, preferred forms of the present utility model is described, it is obvious that under inventive concept of the present utility model, still can make a lot of change.Here, it should be noted that any change made under inventive concept of the present utility model falls within protection domain of the present utility model.
