Description
Technical field
The utility model belongs to technical field of oil field equipment, more particularly to a kind of for dismantling the special of jackscrew in wellhead assembly
Use combination wrench.
Background technique
Currently, what is used is all conventional tool, without special tool in job execution disassembly 250 model wellhead assembly when jackscrew
The problem of tool, field stripping deposits problem both ways, is tool damage first, using conventional tool, it be easy to cause Wrench
Damage, deformation split or be broken.The problem of followed by well head jackscrew and pressure cap damage, when unloading motionless really with spanner, has
The case where being dismantled using pipe wrench, then will lead to jackscrew and pressure cap corner angle be snapped it is bald, sting circle and damage, it is not only time-consuming in this way to take
Power also adds construction cost.The size of monkey wrench opening can be adjusted within the limits prescribed, and versatility compares
By force, it but is easy to loosen at active open, in addition its semi-open mode is engaged, so stability and painstaking ability are limited, is easy to slide
De- and frictionally damage jackscrew, when operation, which slips, the risk hurted sb.'s feelings.Since monkey wrench is forbidden using sleeve extension bar, to torsion
It is required that big situation is inconvenient for use, when use, forbids hammering and instead makes spanner.In addition, double offset ring spanner and the stiff hand of double end are standards
Tool is equally forbidden to use sleeve extension bar, forbids hammering.It is dead although biggish single head solid wrench can carry out pounding hammering
Spanner has the risk for flying up or being broken and hurt sb.'s feelings；It is semi open model at opening for solid wrench, when operation is easy to slip.Conventional extracting tool
In dismantling 250 model wellhead assembly when jackscrew, not only time-consuming and laborious, removal efficiency is low, but also there are security risks.So
It is very necessary for designing a kind of special combination spanner for dismantling jackscrew in wellhead assembly.
Summary of the invention
The purpose of the utility model is to provide a kind of for dismantling the special combination spanner of jackscrew in wellhead assembly, this is dedicated
Combination wrench is used by the combination accessory of interior six sides cross like spanner, the nested cylinder in interior four directions and sleeve extension bar, can be torn open respectively
The pressure cap in 250 model well device on jackscrew and jackscrew is filled, after mating sleeve extension bar loosens jackscrew, can directly rotate hand with hand
Handle, the operation quickly dismantled or tightened, it is time saving and energy saving to dismount, and improves working efficiency, and safe and reliable, do not have skidded,
Obscission.The disassembly of realization jackscrew and pressure cap that can be easy.The special spanner can avoid jackscrew and pressure cap damage, subtract
Light work personnel labor intensity, safe operation is reliable, improves working efficiency, and easy to use, structure is simple, and design is reasonable, cost
It is cheap, it is economic and practical.
The technical solution adopted in the utility model are as follows: it is a kind of for dismantling the special combination spanner of jackscrew in wellhead assembly:
Including interior six sides cross like spanner, the nested cylinder in interior four directions and sleeve extension bar；Six side's cross like spanner include ontology and tightening in described
Screw, the ontology are equipped with interior hexagonal hole, and there are four uniformly distributed handles for welding on the excircle of ontology；The interior four directions is nested
The shape of cylinder is hexahedron, is equipped with square hole in the circular hole of the interior nested cylinder in four directions, square hole side is equipped with threaded hole；Four in described
Side's nesting cylinder is nested in the interior hexagonal hole of ontology, and the screw by being threadedly coupled with the nested cylinder of ontology and interior four directions is tight
Gu；The sleeve extension bar is sleeved on handle.
Further, the interior hexagonal hole is identical with the shape of hexahedron.
Further, the interior hexagonal hole and hexagonal shape are regular hexagon.
Further, the screw is located between two handles, and screw is installed on one of interior hexagonal hole
The centre in side face.
Further, the lever for screwing is welded on the screw.
Further, the screw is the screw with V-arrangement rotating handle.
Further, the length of the sleeve extension bar is not less than 50cm.
The utility model has the beneficial effects that provide it is a kind of for dismantling the special combination spanner of jackscrew in wellhead assembly,
The special combination spanner is used by the combination accessory of interior six sides cross like spanner, the nested cylinder in interior four directions and sleeve extension bar, can
The pressure cap dismounted in 250 model wellhead assembly on jackscrew and jackscrew respectively can be straight with hand after mating sleeve extension bar loosens jackscrew
Switch through fixed handle, the operation quickly dismantled or tightened, it is time saving and energy saving to dismount, and improves working efficiency, and safe and reliable, does not go out
It now skids, obscission, two sleeve extension bars can be used to be sleeved on the hand of two proper angles for the situation big to torque requiremnt
On handle, You Liangming operator exerts oneself simultaneously, the disassembly of realization jackscrew and pressure cap that can be easy.The special spanner can be kept away
Exempt from jackscrew and pressure cap damage, mitigate labor intensity of operating staff, safe operation is reliable, improves working efficiency, easy to use, structure
Simply, design is rationally, low in cost, economic and practical, is easy to promote and use on a large scale.
