And by two side openings on casing head body, it can carry out mending the construction operations such as crowded mud, monitoring and filling equilibrium liquid.Therefore
Casing head is installed in drillng operation, or even is all played the important and pivotal role in oil recovery process.In installation screw thread jacket
, it is necessary to which screw-thread casing head is connected on uppermost surface pipe box cupling by pipe screw thread during tube head, this process needs
Make-up, upper button and operation of linking closely are carried out, is all using artificial make-up, upper button and tight during country's situ of drilling well installation casing head at present
The problems such as button, big there are labor strength, work efficiency is low, the difficulty that links closely.
The content of the invention
Problem to be solved in the utility model is to provide a kind of design of new screw-thread casing head spin-up chain, operation side
Just, it is simple in structure, using rotatable handle, so as to fulfill quickly carrying out make-up, upper button to casing head, linking closely, reduce worker's work
Intensity, work efficiency is high, at the scene can be with Fast Installation casing head.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
Casing head links closely device, which is located at the top of casing head flange disk, including bearing torque metallic plate and connection handle,
Two connection symmetric handles be located at the both sides of the bearing torque metallic plate, close each connection on the bearing torque metallic plate
The position of handle is equipped with some threaded holes in pairs, and the relatively described connection handle of some threaded holes is symmetrical two-by-two, some spiral shells
Pit and the threaded hole position consistency on casing head flange disk.
Further, the bearing torque metallic plate outer edge includes 4 sides, and opposite two sides are symmetrical, wherein two
A symmetrical side is the cambered surface of evagination, two other symmetrical side is plane, and two handles are right positioned at two respectively
In the cambered surface of title.
Further, two symmetrical cambered surfaces correspond to the same center of circle, and the corresponding central angle of the cambered surface is 60 °.
The utility model is suitable for the installation of all kinds of screw-thread casing heads, can greatly save the time of linking closely, and ensures to link closely
Moment of torsion, reduces other security risks during installation casing head of well head operation in the past.
