Abstract
The utility model relates to a derrick docking mechanism for an oil rig derrick and an oil wellhead, which has the structure as follows: a limit guide rail, a support guide rail and a support are respectively connected at the left side and right side of a derrick foundation on a oil wellhead drill floor in sequence from bottom to top; a dual-function cylinder is arranged between two limit guide rails and connected on the derrick foundation, and cylinder rods extending from two ends thereof are connected with the support; the dual-function cylinder is used for adjusting a gadder; and a trailer drilling rig derrick is centered to the center of the oil wellhead and docked with the derrick foundation. In the utility model, the requirement on the driving skills of drivers is not high, the working efficiency of installation is high and the cost is low.
Description
Technical field
The utility model relates to oil drilling and repairing well equipment, particularly relates to the derrick docking mechanism of oil-well rig boring tower centering oil well head;
Background technology
At present, the derrick centering well mouth of oil well of the rig of vehicular, pull-type delivery adopts following mode to carry out usually: it is the sidepiece connection derrick footing at the rig floor of the well head installation of oil well, and the derrick leg that derrick footing is provided with two bearings and rig achieves a butt joint.There are many drawbacks in this kind docking calculation, at first, two bearings on the supporting leg centering derrick footing of derrick, error requirements is difficult to centering in tens millimeters.Secondly, generally need wagon drill or dilatory car to move backward repeatedly during operation, two bearings in derrick on the leg centering derrick footing, this not only requires the driver that consummate driving technology is arranged, and waste a large amount of time, reduce transition efficient, sometimes even will use crane could realize the butt joint of derrick, increased cost of production.
Summary of the invention
The purpose of this utility model is to provide a kind of derrick docking mechanism, and it is a kind of vehicular, a pull-type delivery drilling derrick centering well head, is easy to the convenient mechanism that derrick leg docks with two bearings on the derrick footing.
The technical solution of the utility model is:
The derrick footing left and right end of the utility model on oil well mouth rig floor connects a limit guide rail, a support slide rail, a bearing from bottom to top successively respectively, double acting hydraulic cylinder is between two limit guide rail and be connected on the derrick footing, the cylinder rod that stretch out at the two-way cylinder two ends connects two bearings respectively by pull bar, and two-way cylinder drives bearing and moves to same direction in the first-class stroke of support slide rail, constant speed.
Advantage of the present utility model is as follows:
1, two-way cylinder of the present utility model can drive two bearings left and right moving on limit guide rail, thereby makes the derrick of vehicular, pull-type rig be easy to butt joint, does not need crane gear in the butt joint installation process, has simplified installation steps, has reduced cost of production.
2, the utility model can make wagon drill and towed vehicle be easy to reversing, and the driver who does not need the driving technology consummation just can the centering well mouth of oil well, thereby has saved the plenty of time, and installation work efficient is improved greatly.

The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Among Fig. 1-5: the left side on the derrick footing 10, right two ends connect a limit guide rail 1 from bottom to top successively respectively, a support slide rail 4 and a bearing 3, limit guide rail 1 is the two channel-section steel shape structures that steel plate is welded into counterpart, be welded on the derrick footing 10, supporting slide rail 4 is slide plates of trough of belt, be welded on the derrick footing 10, two-way cylinder 7 is being fixed on the derrick footing 10 by bolt 9 by holder 8 between two limit guide rail 1, the cylinder rod that stretch out at its double acting hydraulic cylinder 7 two ends is connected two bearings 3 respectively by pull bar 5 and bearing pin 6, operation double acting hydraulic cylinder 7, when its cylinder rod is mobile to the left or to the right, drive a left side, right two bearing 3 strokes such as grade, constant speed moves to same direction, guarantees a left side simultaneously, the distance of right two bearings 3 is constant.
During docking operation, the two-way cylinder 7 of control derrick docking mechanism makes bearing 3 that its two ends connect centering derrick leg to the left or to the right, and falls derrick leg, its supporting leg is generally hydraulic cylinder supporting leg or mechanical turn buckle supporting leg, it is seated on the bearing 3, controls the double-act-ing hydraulic J-Horner 7 of derrick docking mechanism once more, mobile support saddle 3 to the left or to the right, carry derrick promptly, make bearing 3 aim at the arrow mark 2 that designs, derrick centering well head then, the butt joint installation of derrick.
