The invention has the advantages that: be 1. applicable to the salvaging in the certain limit in oil gas field and marine oil gas field and send well operations, widely applicable.2. easy and simple to handle, simple in structure, result of use is good.
Brief description of the drawings
Fig. 1 is the apparatus structure schematic diagram that wire rope send well and recovery.
Wherein: 1. reclaim neck, 2. tightening pin, 3. mandrel, 4. top connection, 5. shear pin, 6. shroud, 7. spring, 8. support set, 9. key spring, 10. traction body, 11. keys.
Detailed description of the invention
Referring to Fig. 1, below with reference to embodiment, the present invention will be further described.
A kind of oil drilling and extracting equipment, particularly a kind of wire rope send the device of well and recovery, the recovery neck 1 that comprises mandrel 3 and be connected with mandrel 3 bottom thread, it is characterized in that: described mandrel 3 outer wall tops are provided with the first reducing step, the upper end of this mandrel outer wall also has the second reducing step, be furnished with a series of keys 11 along mandrel 3 outer wall upper ends, one end of this key 11 contacts with the first reducing step and is coordinated with the traction body 10 on being placed on mandrel 3 outer walls by its location other end, between described traction body 10 inwalls and mandrel 3 outer walls, also there is a support set 8, top connection 4 on these support set 8 one end contact the other end and are placed on mandrel 3 with the second reducing step of mandrel 3 contacts, there is a shear pin 5 to run through top connection 4 and mandrel 3, between described traction body 10 lower ends and the lower edge of support set 8, there is the second elastic part 9, described top connection 4 inwalls have reducer, there is the first elastic part 7 to be placed in this reducer.
When work, wire rope is transferred, when key 11 is descending touch need salvage instrument time, wire rope accelerates to transfer, key 11 is by compressive traction body 10, compress the second elastic part 9 simultaneously, the second elastic part 9 will compress support set 8, support set 8 will promote top connection 4 and the first elastic part 7 is up, shear pin 5 is subject to shearing force effect and is cut off, key 11 continues up and shrinks to enter in the instrument that needs to salvage and block, on wire rope, carry, simultaneously first, the second elastic part 7, under 9 active force, top connection 4 is recovered neck 1 and withstands motionless, key 11 is subject to the descending step place that slips into axle 3 of elastic force effect softened, catch on salvaged article, in continuation, carry wire rope, instrument by salvaged go out well head.
And there is a shroud 6, and this shroud 6 is placed on the outer wall of key 11, support set 8 and top connection 4, and described shroud 6 one end have projection, and this projection coordinates with the projection on key 11 outer walls, and the other end of described shroud 6 is connected with the outer wall thread of top connection 4.
