Description

Fishing device

Technical field the invention belongs to the oil pipe fishing device, and particularly a kind of oil gas field oil pipe of realizing removes the fishing device of grabbing the card operation.

Background technology is present, both at home and abroad in the production operation that the oil gas field oil pipe removes, the oil pipe catching device is a pipe elevator when confirming aboveground oil pipe handling, and one, pipe elevator are grabbed the card oil pipe by unidirectional support in tubing coupling lower surface and oil pipe deadweight are realized, when oil-well strata pressure is conducted oneself with dignity greater than oil pipe, scurry on the oil pipe, rely on the well killing fluid kill-job could realize the oil pipe rountrip, both caused the person property to waste, cause oil layer pollution again, the variation of strata pressure also causes security incident easily; Its two, pipe elevator is grabbed the card oil pipe and is realized that by artificial loading and unloading labour intensity is big, production efficiency is low, can not realize operation automation.

Summary of the invention the objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of when realizing aboveground oil pipe handling oil pipe grab the fishing device of card operation.

Task of the present invention is, the inner core of fishing device is the suit urceolus successively, fixed cover, steel ball is set in the upper end and the top connection lower end articulates, lock pressing spring in the ring cavity that inner core and urceolus constitute, inner core, the urceolus bottom is provided with to install in the symmetrical in twos slotted hole carries axle bed, lower pressing shaft seat, in connect bearing pin suit torsion spring and connect L shaped upper lifting claw and L shaped lower pressing claw, outer cylinder diameter is to steel ball is installed, spring, lock-screw crimping inner core semi-round ring shape groove, urceolus is provided with pin and slips the inner core axial slide, top connection top is provided with the ring cavity inwall and offers slotted hole insert double-parabolic slab reed, center clamping wiper block.

The inner core of described fishing device is the suit urceolus successively, fixed cover, steel ball is set in the upper end and the top connection lower end articulates, lock pressing spring in the ring cavity that inner core and urceolus constitute, inner core, the urceolus bottom is slipped to install in the symmetrical in twos slotted hole of sliding sleeve setting and is carried axle bed, lower pressing shaft seat, in connect bearing pin suit torsion spring and connect L shaped upper lifting claw and L shaped lower pressing claw, outer cylinder diameter is to steel ball is installed, spring, lock-screw crimping inner core semi-round ring shape groove, urceolus is provided with pin and slips the inner core axial slide, top connection top is provided with the ring cavity inwall and offers slotted hole insert double-parabolic slab reed, center clamping wiper block.

The present invention has following characteristics: one, by the endwisely slip structure of control L shaped upper lifting claw and L shaped lower pressing claw position of the relative urceolus of inner core, realized putting on the fishing device sending and grabbed the card oil pipe automatically, alleviated operating personnel's operation intensity, improved operating efficiency; They are two years old, urceolus and inner core bottom be provided with install respectively in the symmetrical in twos slotted hole lower pressing shaft seat, on put forward the structure of axle bed, make L shaped upper lifting claw and L shaped lower pressing claw shift out inner core bottom slotted hole, top dead centre immigration inner core bottom slotted hole in lower dead center, the pipe operation is dragged in realization, inner core, urceolus bottom are slipped shift sleeve structure and are realized that L shaped upper lifting claw and L shaped lower pressing claw shift out the inner core slotted hole at top dead centre, lower dead center moves into the inner core slotted hole, realize lowering-in operation, prevent to push up on the oil pipe; Its three, top connection top insert double-parabolic slab reed, the structure of center clamping wiper block has guaranteed that centering sets upright oil pipe.

Description of drawings specifies with embodiment below in conjunction with accompanying drawing.

Fig. 1 shows fishing device embodiment 1 structure chart, and the A-A sectional drawing of Fig. 2 diagrammatic sketch 1, Fig. 3 show fishing device embodiment 2 structure charts, the B-B sectional drawing of Fig. 4 diagrammatic sketch 3.

Among the figure, the 1-inner core; The 2-bearing pin; The 3-upper lifting claw; The 4-lower pressing claw; The 5-spring; The 6-urceolus; The 7-top connection; The 8-steel ball; The 9-felt; The 10-steel ball; The 11-lock-screw; The 12-spring; The 13-pin; The 14-fixed cover; 15-lower pressing claw axle bed; 16-upper lifting claw axle bed; The 17-torsion spring; The 18-packing ring; The 19-cottor pin; The 20-plate spring sheet; The 21-wiper block; The 22-sliding sleeve

The specific embodiment is with reference to accompanying drawing 1, Fig. 2, fishing device work embodiment 1, inner core 1 suit urceolus 6 articulates on the lower contact 7 relative fixed cover 14 and moves to after top dead center, urceolus 6 stops to move together with lower pressing claw 4, inner core 1 is carried on continuing together with upper lifting claw 3, and steel ball 10 cannelure from the interior cover 1 slides to down cannelure, upper lifting claw 3, lower pressing claw 4 immigration inner/outer tube slotted hole under torsion spring 17 effects, upper lifting claw 3, lower pressing claw 4 are thrown off tubing coupling, and the action of pine pipe is finished.
