Abstract

The utility model relates to the technical field of petroleum well cementation, in particular to a mechanical top-drive casing running device. A composite bearing and a sealing element are installed between the lower end of an upper mandrel and the upper end of a lower mandrel of the mechanical top-drive casing running device. The lower end of the upper mandrel is connected with the upper end of a hollow screw of a ball screw pair through two bearing snap rings and multiple key blocks. The lower end of a nut of the ball screw pair and the upper end of a slip guide sleeve are connected and fastened through a bolt. The lower mandrel is sleeved with the slip guide sleeve. Multiple rectangular through holes are evenly distributed in the outer wall of the lower end of the slip guide sleeve in the circumferential direction. Slips are installed in the through holes. The inner side of each slip is provided with multiple concave bevels which are matched with convex bevels arranged on the outer wall of the lower mandrel. According to the mechanical top-drive casing running device, a hydraulic source and a hydraulic pipeline are not needed, a reaction torque device does not need to be installed between the mechanical top-drive casing running device and a top drive device, installation is convenient and fast, and use is safe and reliable.

Description

Casing pipe running device is driven on mechanical type top
Technical field:
The utility model relates to a kind of Cementing technical field, and particularly casing pipe running device is driven on a kind of mechanical type top.
Background technology:
Existing and top are driven the various casing pipe running devices that are connected and are mostly that axle inserts in sleeve body, with internal surface of sleeve pipe clamping or sealing.Its operating principle is generally as follows: the top of driving casing pipe running device on top is connected with top driving device main shaft by screw thread, by driving hydraulic power source or the hydraulic power source that carries drives the annular hydraulic cylinder piston rod of casing pipe running device drive slips downward movement and open in top, make the pincers tooth clamping internal surface of sleeve pipe on slips cylindrical, the torque wrench moment that main shaft can be driven in top passes to sleeve pipe accurately, realizes the connection of sleeve pipe; Can drive by top the hydrophthalmia of casing pipe running device, by mud sprue bushing post, between the axle cylindrical of casing pipe running device and internal surface of sleeve pipe, leather cup is housed, can seal mud, so can start at any time as required mud circulation.
Because most of casing pipe running devices all need hydraulic power source, so just need hydraulic line to be connected to top and drive rig, and will ensure that pipeline and hydraulic cylinder do not rotate, also need to have an anti-torque device to drive and be connected with top.Drive on top is nonstandard product, it is different that appearance and size is driven on the top of various brands, all size, need to design and produce different anti-torque devices and coordinate different tops to order about use, and the on-the-spot inconvenience of installing, the leakage of hydraulic oil when connecting fluid pressure pipeline, also can be there is.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of mechanical type top and drives casing pipe running device, and this device has been realized does not need hydraulic power source and hydraulic line, does not need and anti-torque device is installed between driving in top, quick and easy for installation, safe and reliable.Overcome existing top and driven casing pipe running device and need hydraulic power source and hydraulic line, need to and top anti-torque device is installed between driving, install inconveniently, when use, easily there is the deficiency of hydraulic fluid leak.
Technical solution adopted in the utility model is: casing pipe running device is driven on a kind of mechanical type top, comprises upper spindle, slips fairlead, lower spindle and slips, upper spindle upper end is designed with nipple, upper spindle and lower spindle center have hydrophthalmia, between upper spindle lower end and lower spindle upper end, composite bearing and seal are installed, upper spindle lower end is connected by two carrying snap rings and multiple key piece with the hollow lead screw upper end of ball screw assembly, the nut lower end of ball screw assembly, is connected fastening by bolt with slips fairlead upper end, slips fairlead is sleeved on lower spindle outside, on the outer wall of slips fairlead lower end, be circumferentially evenly equipped with multiple rectangle open-works, this open-work is provided with slips, slips inner side is designed with multiple indents inclined-plane and matches with the outer convex inclined plane on lower spindle outer wall, lower spindle upper end is designed with a columniform shoulder, under shoulder, between the bearing surface of the hollow lead screw endoporus of transverse plane and ball screw assembly,, loading bearing is installed, lower spindle lower end is provided with leather cup and guide head.
The beneficial effects of the utility model are: the utility model does not need hydraulic power source and hydraulic line, do not need and anti-torque device is installed between driving in top, quick and easy for installation, safe and reliable.
Brief description of the drawings:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, casing pipe running device is driven on a kind of mechanical type top, comprises upper spindle 1, slips fairlead 3, lower spindle 4 and slips 5, upper spindle 1 upper end is designed with nipple, upper spindle 1 has hydrophthalmia with lower spindle 4 centers, between upper spindle 1 lower end and lower spindle 4 upper ends, composite bearing and seal 10 are installed, upper spindle 1 lower end is connected by two carrying snap rings 8 and multiple key piece 9 with the hollow lead screw upper end of ball screw assembly, 2, the nut lower end of ball screw assembly, 2 is connected fastening by bolt with slips fairlead 3 upper ends, slips fairlead 3 is sleeved on lower spindle 4 outsides, on slips fairlead 3 lower end outer walls, be circumferentially evenly equipped with multiple rectangle open-works, this open-work is provided with slips 5, slips 5 inner sides are designed with multiple indents inclined-plane and match with the outer convex inclined plane on lower spindle 4 outer walls, lower spindle 4 upper ends are designed with a columniform shoulder, under shoulder, between the bearing surface of the hollow lead screw endoporus of transverse plane and ball screw assembly, 2, loading bearing 11 is installed, lower spindle 4 lower ends are provided with leather cup 6 and guide head 7.
While carrying out spinner operation, top is driven first to transfer slips fairlead 3 is pressed on casing coupling, slips fairlead 3 is motionless, upper spindle 1 forward, thereby the axial linear movement that ball screw assembly, 2 becomes rotatablely moving of upper spindle 1 into lower spindle 4 moves upward axle, inclined-plane on lower spindle 4 external cylindrical surfaces outwards opens slips 5, thereby clamping internal surface of sleeve pipe, realize with top driving force spinner, slips 5 wedgings simultaneously, between casing string and lower spindle 4, can allow axle bear the weight of whole casing string in the time transferring whole casing string.Reversion is driven on top, and lower spindle 4 is descending, and slips 5 resets under the effect of spring.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as meet, all within protection domain of the present utility model.
