Abstract
Provided by the utility model is a kind of constructing device for fishing for the drilling rod that fractures, including latching connector and catches head, catches the lower end that head is firmly welded on latching connector.During construction by the device by latching connector screwed connection in upper end drilling rod lower end, then move up and down upper end drilling rod, head to be captured is gradually increased rig pull out force after capturing the groove for the drilling rod that fractures, and the drilling rod that will fracture extracts ground.It present apparatus simple processing, can dismantle, on-site consolidation and can reuse.Simplicity is dismounted in work progress, safe and practical, construction effect is high, cost is low.Guarantee successfully to fish for the drilling rod that fractures, what drilling rod fractureed suitable for boring procedure fishes for operation.
Description
Technical field
The utility model belongs to engineering construction field, and the construction dress for the drilling rod that fractures is fished in specifically a kind of boring procedure
Put, the operation suitable for salvaging the drilling rod that fractures during drilling.
Background technology
During earth drilling, often meet drilling rod and block caused by fatigue rupture, corrosion failure, mechanical damage and accident are destroyed
Bore, disconnected bar accident.Drilling rod fractures, that is, refers in drilling or when handling other boring accidents, because drilling rod stress is excessive, make drilling rod
Or tool joint fractures, by drilling tool drop in drilling.
After drilling rod fractures, if do not taken out the drilling rod that fractures, drilling can not continue, and therefore drilling is interrupted even cancels.For
The drilling rod that will fracture is fished for out, and fracture thread making or female coupling tap in drilling rod of conventional die nipple insertion entangles the body of rod thread making that fractures.Due to boring
Bar intensity is high, fracture place's out-of-flatness, and disconnected bar, often because bit freezing resistance is big, die nipple and female coupling tap thread making are difficult and shallow, and the button made is difficult
Bear to extract the pulling force and moment of torsion of disconnected bar, therefore fishing success ratio is low and time length, influences work efficiency and to native around（Rock）Body disturbs
Greatly.
Utility model content
The purpose of this utility model is to provide a kind of constructing device for fishing for the drilling rod that fractures, and fishes for success rate to improve and adds
The fast activity duration, it is ensured that fish for success, avoid repeatedly disturbing hole wall, and improve and fish for operation work efficiency, it is quick that work is fished in guarantee
Safety.
Success rate is fished for improve, the utility model is with reference to rotary tong buckle structure is taken, using in the interlocking head section of drilling rod
Groove, the drilling rod that will fracture block, and reach the purpose for fishing for the drill rod boring tool that fractures.It is well-designed by field test, technical staff
The constructing device of the present utility model for fishing for the drilling rod that fractures.
Concrete structure is：Fishing for the constructing device for the drilling rod that fractures includes latching connector, catches head, catches head and is firmly welded on lock
The lower end of joint, latching connector is by screwed connection in upper end drilling rod lower end.
Upper end drilling rod is moved up and down during construction, after head to be captured captures the groove for the drilling rod that fractures, rig is gradually increased and pulls out
Power, the drilling rod that will fracture extract ground.
Described latching connector is shaped as tubulose, there is a groove on external diameter.
Described seizure head shapes are in U-typed, catch head bore and match with the drilling rod groove caliber size that fractures.
The constructing device of the present utility model for fishing for the drilling rod that fractures, simple processing is simple to operate, and success rate is high, is applied to
The drilling rod that fractures with latching connector is fished for, and construction speed is fast, processing cost is low, is worthy to be popularized in the operation for fishing for the drilling rod that fractures
Use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is construction operation schematic diagram；
Reference：1- latching connectors, 2- catch head, 3- upper ends drilling rod, and 4- fractures drilling rod, 5- rigs.
Embodiment
In the examples where no specific technique or condition is specified, according to the technology described by document in the art or condition or
Person is carried out according to product description.Agents useful for same or the unreceipted production firm person of instrument, being can be by buying the normal of acquisition
Advise product.
As shown in figure 1, the constructing device of the present utility model for fishing for the drilling rod that fractures includes latching connector 1 and catches first 2, interlocking
First 1 one end is connected on the drilling rod of upper end, and the device is connected during construction by the other end with catching head welding with upper end drilling rod.
Described latching connector is shaped as tubulose, there is a groove on external diameter.
Described seizure head shapes are in U-typed, catch head bore and match with the drilling rod groove caliber size that fractures.
The present apparatus is made using steel, catches sheet metal thickness and the processing of plane scale visual actual conditions of head, construction
When moved up and down by catching head in hole, it is steady that the drilling rod that will fracture clasps card, is then gradually increased rig group power, the drilling rod that will fracture is slow
It is slow to propose ground, the operation that the drilling rod that fractures is fished for when rig well-digging or pore-creating is bored suitable for geology.
During construction, as shown in Fig. 2 operating personnel's specific implementation step is for example following：
Step 1：U-typed seizure head is first firmly welded on to the lower end of latching connector, then by with the latching connector for catching head
Access the drilling rod lower end of rig.
Step 2：Start rig, continuing jointed rod to the drilling rod that fractures has " groove " place, then moves up and down drilling rod, makes to catch
Catching head will fracture that to clasp card steady for drilling rod at " groove " place.
Step 3：When strainer card surely fractures drilling rod " groove ", it is gradually increased rig and dials power, makes the drilling rod disengagement that fractures
Bit freezing position, then fish for out ground by the normal operating drilling rod that will fracture.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；The common skill of this area
Art personnel should be understood：It can still modify to the technical scheme described in foregoing embodiments, or to its middle part
Technical characteristic is divided to carry out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality
The spirit and scope of new each embodiment technical scheme.
