Abstract
Provided is a rapid connection device for hoisting and releasing an oil tube. A hoisting ring, a connection rod and a cone are connected into a whole. A tapered inner thread is arranged at the upper portion of the oil tube. A tapered outer thread of an elastic buckling jaw is matched with the taper inner thread at the upper portion of the oil tube and is milled to be a strip. The lower inner part of the elastic buckling jaw is a tapered hole matched with the outer circular conical surface of the cone. The connection rod and the cone penetrate through the elastic buckling jaw and a releasing sleeve. An inner tapered hole in the lower portion of the releasing sleeve covers the upper tapered surface of the strip milled on the elastic buckling jaw. The strip milled at the lower portion of the elastic buckling jaw is pressed by the releasing sleeve, is placed in the inner thread at the upper portion of the oil tube after retracting, and then expands, so that the strip and the oil tube are buckled in a threaded mode and are connected into a whole, and the oil tube is connected rapidly. After retracting from the interior of the elastic buckling jaw, the cone can be rapidly separated from the oil tube through the mode that the releasing sleeve presses the elastic buckling jaw. The rapid connection device can be connected and disconnected with the oil tube rapidly, the oil tube is hoisted and released easily and conveniently, working efficiency is high, the structure is simple, and operation is convenient.
Description
Technical field
The utility model is that petroleum well workover hangs the instrument that oil pipe is used, and is a kind of oil pipe Quick Connect Kit that hangs.
Background technology
In oil well process, the oil pipe that lies in ground be sling and the oil pipe in well is lain in to ground, in this process, need to there is linkage that oil pipe is connected with travelling block, be to be connected with the male thread of plug and the box thread of oil pipe at present, plug is suspended on travelling block, then oil pipe is hung, adopt plug to hang oil pipe and need thread screw, work cumbersome, labor strength is large, inefficiency, engineering time is long, can not meet site operation requirement.For this reason, technician has developed a kind of device and has solved this problem, as Chinese patent 201120014458.4 < < hang drilling rod Rapid chuck > >, adopt this device to hang oil pipe easy, operating efficiency is high, and labor strength is low.But its complex structure, inconvenient operation.
Summary of the invention
The purpose of this utility model is a kind of oil pipe Quick Connect Kit that hangs of design, makes it to hang oil pipe easy, and operating efficiency is high, and labor strength is low, and simple in structure, easy to operate.
The purpose of this utility model is achieved in that and comprises suspension ring, connecting rod, discharge cover, elasticity make-up pawl, cone, oil pipe, suspension ring, connecting rod, cone links into an integrated entity, conical internal thread is arranged at the top of oil pipe, the conical external screw thread of elasticity make-up pawl and the upper taper internal thread of oil pipe match, the conical external screw thread portion milling of elasticity make-up pawl is split into bar body, make its conical external screw thread portion can enlargement and contraction, the lower inside of elasticity make-up pawl is bellmouth, the outer conical surface of this bellmouth and cone matches, connecting rod, cone is through elasticity make-up pawl, discharge cover, discharge on the bar body that cover bottom female cone port lid is split in the milling of elasticity make-up pawl on the conical surface.
The beneficial effects of the utility model are: after making to shrink with the bar body that the bottom milling of release cover compacting elasticity make-up pawl is opened, put in the internal thread on oil pipe top, the bar body expansion that the bottom milling of elasticity make-up pawl is opened, both link into an integrated entity by screw thread make-up, upper lifting ring, cone can not be shunk elasticity make-up pawl, thereby connected pipes fast, cone can make again elasticity make-up pawl and oil pipe Quick release with the bar body that the bottom milling of release cover compacting elasticity make-up pawl is opened from elasticity make-up pawl inside is exited, therefore, the utility model can be connected and throw off fast with oil pipe, hang oil pipe easy, operating efficiency is high, labor strength is low, and simple in structure, easy to operate.
Accompanying drawing explanation
Accompanying drawing is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model comprises suspension ring 1, connecting rod 2, discharge cover 3, elasticity make-up pawl 4, cone 5, oil pipe 6, suspension ring 1, connecting rod 2, cone 5 links into an integrated entity, conical internal thread is arranged at the top of oil pipe 6, the conical external screw thread of elasticity make-up pawl 4 and the upper taper internal thread of oil pipe 6 match, the conical external screw thread portion milling of elasticity make-up pawl 4 is split into bar body, make its conical external screw thread portion can enlargement and contraction, the lower inside of elasticity make-up pawl 4 is bellmouth, the outer conical surface of this bellmouth and cone 5 matches, connecting rod 2, cone 5 is through elasticity make-up pawl 4, discharge cover 3, discharge on the bar body that cover 3 bottom female cone port lids are split in 4 millings of elasticity make-up pawl on the conical surface.
When needs are sling oil pipe, the utility model is put into oil pipe internal thread, upper lifting ring 1, be connected to the bar body that the up conical external screw thread portion milling that struts elasticity make-up pawl 4 of cone 5 under suspension ring 1 is opened, elasticity make-up pawl 4 and oil pipe 6 are linked into an integrated entity, thereby oil pipe 6 can be sling, while putting down oil pipe 6, press down suspension ring 1, cone 5 and elasticity make-up pawl 4 are thrown off, press down again and discharge cover 3, the bar body that the conical external screw thread portion milling of elasticity make-up pawl 4 is opened is shunk, elasticity make-up pawl 4 can be taken out in oil pipe linchpin.
