Abstract

The utility model discloses a general throwing and salvaging device, comprising a joint, a support piece, a guide tube, a spring, a slider, a guide pillar, a lock nut, a shrinking claw, an outer tube, a righting ring and a salvaging spear, wherein the lock nut, the shrinking claw and the guide tube are in screwed connection in turn and the end of the guide pillar is loaded into the guide tube and the slider hole is rightened to the guide tube slide and the slider is mounted and the spring and the support piece are mounted on the upper end of the guide tube in turn and then in screwed connection with the joint, the outer tube and the righting ring in turn. When the throwing and salvaging device is lowered, the salvaging spear is impacted and the shrinking claw is stricken to compress the spring, thus the slider is switched into throwing state along the slide of the guide tube and the spring resets and the slider accomplishes the throwing state switch and the shrinking claw clips or unlocks the salvaging spear, thereby integrating the throwing with salvaging. The throwing and salvaging device has features of strong generality, convenient operation, simple and durable simple and simple maintenance.

Description

Universal throw in catcher

Technical field

The utility model belongs to drilling engineering field in oil, colliery and the geological prospecting, is specifically related to a kind of universal throw in catcher.

Background technology

When oil exploitation, geological prospecting, often need carry out pulling to downhole instrument, known throw in catcher divides two kinds at present: the one, adopt special-purpose throw in catcher, pulling specific instrument or structural member; The 2nd, adopt split type throw in catcher, use dispenser when promptly throwing in, use fisher during salvaging.

The shortcoming of these two kinds of throws in catcher is, the throw in catcher model is various, and complex operation uses limitation strong, complex structure, easy break-down.Special-purpose throw in catcher can only carry out pulling to one or more instruments, the structural member of appointment, needs in the use frequently to change the different model throw in catcher, and structure is loaded down with trivial details, needs the running check maintenance; Split type throw in catcher is carrying out throwing, need changing throw in catcher when dragging for conversion, and for the well of different-diameter, the fishing spear of different length or different-diameter needs a whole set of throw in catcher of changing, and requirement is equipped with multiple model throw in catcher.Workload when above-mentioned throw in catcher is operated is big, inefficiency.

Summary of the invention

In order to overcome the deficiency that exists in the existing throw in catcher technology, the utility model provides a kind of universal throw in catcher.

The purpose of this utility model is to solve the problem of existing throw in catcher versatility difference of a great variety, alleviates the working strength in the pulling operation, improves the pulling success rate.

The utility model is realized by following form: this universal throw in catcher, form by joint 1, support member 2, guide cylinder 3, spring 4, slide block 5, lead 6, locknut 7, contraction pawl 8, urceolus 9, centering ring 10 and fishing spear 11, wherein locknut 7, contraction pawl 8, lead 6 are threaded successively, the lead 6 ends guide cylinder 3 of packing into, slide block 5 holes are aligned guide cylinder 3 slideways, slide block 5 is installed, by guide cylinder 3 upper ends pack into successively spring 4, support member 2, be threaded successively with joint 1, urceolus 9, centering ring 10 then.

The utility model has adopted following technical scheme: throw in catcher is transferred and is impacted fishing spear 11 in the process, bump shrinks pawl 8 compression springs 4, make slide block 5 switch commit condition along the slideway in the guide cylinder 3, spring reset slide block 5 switches commit condition to be finished, shrink pawl 8 and block or decontrol fishing spear 11, realize throwing in one.

It is characterized in that: fishing spear 11 bumps shrink pawl 8 once, and snap close state and trip status switch once.Guide cylinder 3 is provided with slideway, satisfies under snap close state and the trip status, and the working position of slide block 5 exchanges demand.It is replaceable to shrink pawl 8, is furnished with plurality of specifications and shrinks pawl, is suitable for the fishing spear 11 of different length or different-diameter specification.Centering ring 10 is replaceable, is furnished with the plurality of specifications centering ring, is suitable for the well of different-diameter.Be furnished with locknut 7, can adjust, make it be in the optimum position, improve the pulling success rate the position of shrinking pawl 8.

The utility model has following advantage: have the well of the centering ring of plurality of specifications with adaptive different-diameter.Shrinking claw portion length can regulate, to adapt to the fishing spear of different length.Be equipped with different contraction pawls, can adapt to the fishing spear of different-diameter.This throw in catcher highly versatile, easy and simple to handle, simple in structure durable, maintaining is simple.

Description of drawings

Accompanying drawing 1 is the universal throw in catcher structural representation of the utility model.

Accompanying drawing 2 is the universal throw in catcher snap close of the utility model view.

Accompanying drawing 3 is the universal throw in catcher trip status of the utility model schematic diagrames.

Figure center tap 1, support member 2, guide cylinder 3, spring 4, slide block 5, lead 6, locknut 7, contraction pawl 8, urceolus 9, centering ring 10, fishing spear 11.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified:

Among Fig. 1, support member 2 is put into joint 1, cover upper spring 4, guide cylinder 3 is screwed on the joint 1 by being threaded, screw thread is screwed onto about half, lead 6 is put into by guide cylinder 3 other ends, and rotation makes the sky that passes lead 6 align the slide groove of guide cylinder 3, and slide block 5 is packed into, again guide cylinder 3 is screwed with joint 1 screw thread place, locknut 7 is screwed to and shrinks on pawl 8 screw threads, will shrink pawl 8 and be mounted in lead 6 screwed holes, adjusts and shrinks locking locknut 7 behind pawl 8 positions, urceolus 9 is screwed on the guide cylinder 3, the centering ring 10 of required specification is installed, and corresponding different size fishing spear 11 is installed corresponding specification contraction pawl 8 and is got final product.

During actual the use, as throw in operation, then with shrinking pawl 8 in the fishing spear 11 bump throws in catcher, make throw in catcher be in Fig. 2 snap close state, with rope instrument is put to the shaft bottom, and once clashed into, make throw in catcher switch to Fig. 3 trip status, propose throw in catcher and get final product.As salvage operation, and before going into the well throw in catcher is clashed into to trip status, put to the shaft bottom, and make the interior contraction of fishing spear 11 bump throws in catcher pawl 8 once, make throw in catcher switch to Fig. 2 snap close state, throw in catcher and fishing spear 11 are carried to well head.

Above-described only is preferred true mode of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
