Description
Technical field
The present invention relates to oil field oil, the workover tools of water well operation, specifically full-enclosed oil pipe antisitic defect pipe wrench.
Background technology
In the oil-water well workover treatment in oil field and downhole tool maintenance process, it is necessary to connect spiral shell to oil pipe using pipe wrench
Line, downhole tool connection screw thread dismantled or assembled.Existing pipe wrench is simple, is revolved according to the size of caliber when use
Turn adjusting nut, the jaw of pipe wrench is made to be adapted to caliber, then allowing jaw to block workpiece to be dismounted, firmly rotation can be by it
Dismounting or assembling.Only have two-point contact, the pincers dental inlay by pipe wrench to enter in workpiece body between existing pipe wrench and the workpiece dismounted
Realize both bite strap start building part rotation, so that the connection screw thread of workpiece is dismantled or is tightened, this pipe wrench when in use exist with
Lower problem：
1, contact area is small, and contact point stress is high, is easily damaged workpiece, workpiece is made to deform, reduce the use of workpiece
Performance, it is also possible to workpiece be made to scrap.
2, the pincers tooth of pipe wrench is easy fatigue wear, so that the performance of workpiece is deteriorated, causes to generate between pipe wrench and workpiece
It skids, on the one hand can tear and hinder workpiece surface；On the other hand operator can be made to lose reaction force suddenly and fall down, causes safe thing
Therefore.
3, when workpiece surface has greasy dirt, the pincers tooth of pipe wrench can not be engaged workpiece, can also skid, and occur above-mentioned 2nd
Problem.
For above-mentioned phenomenon, the thorough method of neither one solves so far, and scene can only be by repeatedly clear with wire brush
The pincers tooth or multiple rotary adjusting nut for managing pipe wrench are dehisced to adjust pipe wrench, change the operating point of the pincers tooth of pipe wrench.Make the two
Method can only solve the problems, such as the fraction problem of the 2nd, 3 two problem in above-mentioned 3, cannot solve the problems, such as the 1st, pars affecta
Position loses erosion resistant coating and is easy to be corroded, and shortening volume enters well workpiece service life.
By retrieval, application number 201510466164.8, applying date 2015.07.31 discloses a kind of pressure pipe pincers comprising
One handle, one and the hinged jaw outrigger of handle and a detachable pressure pipe jaw as described above, jaw outrigger have one
Accommodating space for placing pressure pipe jaw.Half jaw of detachable pressure pipe jaw uses two parts group of flexible connection
At, it can be in the more uniform pressure of tube surface application for waiting for ring pressure during ring pressure, and then avoid by pressure unevenness
Weighing apparatus leads to the wrinkle of card pressure linking pipe fitting, leakage.Pressure pipe pincers of the present invention use above-mentioned ring bar hold and combine hinge
The structure of connecting handle, overall structure is simple, of low cost and reliability is high.
Technology disclosed above, can be more equal in the tube surface application for waiting for ring pressure during ring pressure although disclosing
Even pressure, but compared with the application, the cladding power and open file of the application simultaneously differ, and the technical solution of the application uses
The outside that the interior clutch block is clasped on the inside of outer clutch block blocks and scatters very convenient, and the above-mentioned prior art is not
Have, the prior art can not solve this technical problem.The locking device of the application setting simultaneously can prevent the present invention from quilt
Dismounting workpiece separates.The prior art can not solve this technical problem.
Invention content
