Technical field:
The present invention relates to a kind of land petroleum equipment, particularly the false rotating-table apparatus of a kind of oblique straight well adjustable-angle well head.
Background technology:
In oblique straight well rig operation process, wellhead platform need to carry out with the difference at derrick angle of inclination the adjustment of different angles, because the volume of the false rotating disk platform of well head is larger, and the drilling machine well mouth platform space is limited, and false rotating disk quality is large, its adjustment angle is also fixing in addition, therefore needs a set of automation angle-adjusting mechanism of specialized designs.
Summary of the invention:
The technical problem to be solved in the present invention is to provide the false rotating-table apparatus of a kind of oblique straight well adjustable-angle well head, this device has been realized the false rotating disk automation of well head angle adjustment, reduce taking up room of the false rotating-table apparatus of well head, improve the automaticity of wellhead assembly, reduce labour intensity, improve drillng operation efficiency.Overcome the false rotating disk platform by volume of existing well head large, can not automation adjust angle, adjusted angle and do not fix inaccurate deficiency.
The technical solution used in the present invention is: the false rotating-table apparatus of a kind of oblique straight well adjustable-angle well head is comprised of false turntable unit, rig floor unit and hydraulic cylinder unit; False turntable unit comprises false rotating disk, hydraulic cylinder bracing frame and false rotating disk angle index dial are welded on the left surface of false rotating disk, on false rotating disk angle index dial, be designed with a plurality of circular holes, hinge ear seat is welded on the lower surface of false rotating disk, the angular transducer fixed mount is fixed on false rotating disk, and angular transducer is fixed on the angular transducer fixed mount; The rig floor unit comprises rig floor and false carousel supports ear seat, false carousel supports ear seat comprises false carousel supports ear seat upper cover and false carousel supports ear seat base, false carousel supports ear seat upper cover and false carousel supports ear seat base are bolted, rig floor angle fixed disk and false carousel supports ear seat base are welded on rig floor, on rig floor angle fixed disk, be designed with a plurality of circular holes, cylinder ends ear seat is welded on the left surface of rig floor below; Hydraulic cylinder unit comprises hydraulic cylinder, piston rod and ears ring, and piston rod is threaded with the ears ring; The rotating shaft of false rotating disk both sides is arranged in false carousel supports ear seat, the axle center of false carousel supports ear seat is concentric with the derrick center of rotation, between false rotating disk angle index dial and rig floor angle fixed disk, can connect location by fixed pin shaft, the ears ring is connected with hinge ear seat pin axle, and hydraulic cylinder is connected with cylinder ends ear seat pin axle.
The invention has the beneficial effects as follows: the present invention is owing to having adopted hydraulic cylinder and angular transducer, thereby have the function of the false rotating disk automation of well head angle adjustment, and reduce taking up room of the false rotating-table apparatus of well head, improve the automaticity of wellhead assembly, reduce labour intensity, improve drillng operation efficiency.
