Description
Technical field
The utility model relates to oil, the gas drilling kit field of coring, and especially a kind of core-extracting toolsinternal barrel checks load push-pull, the inspection of the coring tool when mainly being applicable to ocean or land coring operation.
Background technology
At present the normal core-extracting tool in the drilling well field is still also using a large amount of steel inner cores at home, for the ease of transportation and protection inner core, generally all is to take coring inner drum is put into mode among the urceolus of coring.Often in order to pursue the drilling well timeliness, require in advance coring tool to be maintained in the place and check at the scene, during by the time coring operation, coring tool just directly connects drilling tool and enters well.The steel inner core often all be with screw thread with hang assembly and be connected because ground on the scene coring tool is for keeping flat, steel inner core and suspension assembly are conducted oneself with dignity near 0.5 ton, normally pull out inner core inspection by hanging device or manpower, time-consumingly require great effort again; At sea offshore boring island has the help of hanging device, but is subject to the place, deck, and inner core pulls out also from urceolus wastes time and energy.No matter manpower still adopts hanging device, all there is labour intensity in the scene greatly and potential safety hazard, also affects instrument Inspection timeliness simultaneously.
Summary of the invention
The purpose of this utility model is for lacking special-purpose push-and-pull instrument problem in the prior art, providing a kind of core-extracting toolsinternal barrel that not affected by manpower, place and hanging device to check load push-pull.
In order to solve above technical problem, the utility model is achieved through the following technical solutions:
Core-extracting toolsinternal barrel checks that load push-pull comprises sleeve, inner core joint, leading screw and leading screw platen; Wherein: sleeve one end is connected with the leading screw platen, and the sleeve other end is provided with interior or external screw thread; Leading screw and leading screw platen consist of along quill to rotation cooperates, the inner core joint places in the sleeve, inner core joint one end is provided with screw thread, the inner core joint forms vertically with leading screw that reciprocating sliding cooperates, leading screw other end connection driving mechanism.
Link to each other by swivel joint between inner core joint and leading screw, forming vertically by swivel joint and leading screw, reciprocating sliding cooperates.
The inner core joint is connected by the bearing pin that radially arranges with swivel joint.
Sleeve lining is provided with track, and the inner core joint slides along the track of sleeve lining; Inner core joint or swivel joint and leading screw consist of vertically by setting up convex edge and limited block separately that reciprocating sliding cooperates, and the driving mechanism of leading screw comprises Mechanical Driven, motor-driven or hydraulic pump drive, and wherein Mechanical Driven comprises spanner, rotating handles or gear drive.
Advantage of the present utility model: adopt the leading screw rotation mode to promote and the pulling coring inner drum, thereby can effectively reduce manpower, site safety is laborsaving to save time, and effectively improves the timeliness that coring tool checks.
Description of drawings
Fig. 1 is that coring tool of the present utility model checks the load push-pull structural representation
Mark among the figure: 1. sleeve; 2. inner core joint; 3. bearing pin; 4. screw; 5. swivel joint; 6. leading screw; 7. leading screw platen; 8. rotating handles.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 1, core-extracting toolsinternal barrel of the present utility model checks that push-pull device at fixed is comprised of sleeve 1, inner core joint 2, swivel joint 5, bearing pin 3, screw 4, leading screw 6, leading screw platen 7, rotating handles 8.Leading screw platen 7 is by the end of screw fastening at sleeve 1, and the other end of sleeve 1 is processed with interior screw thread or male thread, in order to achieve a butt joint with the screw thread at coring tool urceolus two ends, the inwall of sleeve 1 is axially arranged with track.Inner core joint 2 front ends are processed with internal thread or the external screw thread that is connected with core-extracting toolsinternal barrel, and inner core joint 2 places on the track in the sleeve 1, and are connected (also can directly be connected with screw mandrel 6) with swivel joint 5 by bearing pin 3.Swivel joint 5 and the leading screw 6 junctions inside and outside convex edge by minute being located at swivel joint 5 and leading screw 6 be fixed on screw mandrel 6 screwing 4(and be equivalent to limited block in the technical scheme), stopping that realization swivel joint 5 and screw mandrel 6 front and back move back and forth cooperates, can guarantee again simultaneously screw mandrel 6 rotations and swivel joint 5 does not rotate, and the slide force that leading screw 6 rotations are produced passes to core-extracting toolsinternal barrel by inner core joint 2 levels.Rotating handles 8 is connected with leading screw 6 by nut. and the rotating handles 8 here also can directly adopt open-end wrench or pipe wrench and so on to act directly on screw mandrel, and effect is to get final product to screw mandrel is afterburning, certain also can adopt motor-driven or hydraulic pump drive.
During use, coring tool urceolus pin thread thread protector is dismantled in ground on the scene, and the undergauge cover that also inner core is exposed is simultaneously dismantled, and inner core joint 2 and undergauge are overlapped pipe nipple with being threaded.Dismantle the top connection of coring tool front end with chain wrench, the urceolus splice combinations that sleeve 1 and leading screw platen 7 formed is connected on the pin thread of urceolus.Shake counterclockwise rotating handles 8, leading screw 6 rotates by leading screw platen 7, and swivel joint 5 and inner core joint 2 did not rotate when leading screw 6 rotated, and moved ahead thereby promote forward swivel joint 5, swivel joint 5 passes to inner core joint 2 by bearing pin 3 with thrust, thereby promotes the core-extracting toolsinternal barrel reach.After the suspension assembly of core-extracting toolsinternal barrel exposes, rotating handles 8 stops operating, after will hanging the assembly inspection and maintenance, clockwise rotate rotating handles 8, leading screw 6 clockwise rotates again, and leading screw 6 rotates the pulling force that produces and passes to core-extracting toolsinternal barrel by swivel joint 5, bearing pin 4 and inner core joint 2, coring inner drum is pulled out the urceolus of coring, after exposing undergauge cover pipe nipple, the rotating handles 8 that stops operating, thus finish the inspection work that undergauge overlaps pipe nipple.
The utility model rotates the push-and-pull coring inner drum by leading screw, has greatly alleviated on-the-spot labor operation intensity, has also greatly improved operation timeliness and the job safety of on-the-spot checking tool simultaneously.
