Description
Technical field:
The present invention relates to a kind of oil and gas drilling and coring delivery technical field, particularly a kind of guarantor's type coring tool neck bush puller.
Background technology:
At scall, core at present, all adopt guarantor's type coring tool, this instrument is also equipped with one deck plastic inner lining cover in inner core, while going out the heart, plastic inner lining cover is pulled out together with rock core in inner core, reaches the object of protection rock core shape, is therefore guarantor's type coring tool.Do not have at present special tool that plastic inner lining cover is pulled out together with rock core from inner core.Because plastic inner lining is enclosed within inner core, only expose 80mm, plastic bushing is soft again.General employing at present, the rope made of hemp is tied up on the plastic bushing that only exposes 80mm and is pulled outward.Owing to there being mud lubrication on plastic bushing, the rope made of hemp is easy to live de-on plastic bushing.Live at the scene in taking off and tie up again, again and again until pull out.Once there be the grains of sand that inner core and plastic bushing is stuck.By this way, be just difficult to plastic bushing to pull out from inner core.Even if it is de-that the rope made of hemp of tying up on plastic bushing is not lived, because inner core does not have fixed mechanism, while using energetically, inner core is also and then walked together sometimes.Not including of grains of sand card is too dead, again and again sometimes can also pull out, if card is excessively dead, that just cannot be pulled out.Only have with oxygen inner core is cut open, take out plastic bushing and rock core.So not only lost time but also consumable material.Sometimes a bite well will destroy several inner cores, causes the great waste of material.In a word, the subject matter that prior art exists is: plastic bushing does not have clamp mechanism, and outside pulling force effect is less than on plastic bushing: inner core does not have fixed mechanism, is difficult to produce relative motion between plastic bushing and inner core.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of guarantor's type coring tool neck bush puller, and this device has been realized and plastic inner lining cover can have been pulled out together with rock core from inner core, and success rate is high, simple in structure, easy to operate, safe and reliable.Overcome the deficiency that existing plastic inner lining cover is difficult to pull out from inner core.
The technical solution used in the present invention is: a kind of guarantor's type coring tool neck bush puller, comprises internal diameter pulling force bouncing plate, external diameter lock lobe, internal diameter lock lobe and center bolt, external diameter lock lobe is connected with internal diameter lock lobe right-hand member, plastic bushing right-hand member inserts in the gap between external diameter lock lobe and internal diameter lock lobe, center bolt left end connects internal diameter pulling force bouncing plate, internal diameter pulling force bouncing plate outer is stuck on the interior step of external diameter lock lobe, locking pressure plate screwed connection is on center bolt, locking pressure plate is by thrust bearing connecting external diameter thrust lock tube, external diameter thrust lock tube is sleeved on external diameter lock lobe and is stuck on the outer step of external diameter lock lobe, center bolt right-hand member is set with thrust plate, on inner tank theca, connect thrust base plate, between thrust base plate and upper thrust plate, by distance rod, be connected, nut screwed connection is on center bolt, between nut and upper thrust plate, thrust bearing is installed, on locking pressure plate and nut, be equipped with the handle hole that can insert boosting-rod.
The invention has the beneficial effects as follows: the present invention can pull out plastic inner lining cover together with rock core from inner core, and success rate is high, simple in structure, easy to operate, safe and reliable.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is structural representation of the present invention.
The specific embodiment:
As shown in Figure 1, a kind of guarantor's type coring tool neck bush puller, comprises internal diameter pulling force bouncing plate 4, external diameter lock lobe 5, internal diameter lock lobe 6 and center bolt 10, external diameter lock lobe 5 is connected with internal diameter lock lobe 6 right-hand members, plastic bushing 2 right-hand members insert in the gap between external diameter lock lobe 5 and internal diameter lock lobe 6, center bolt 10 left ends connect internal diameter pulling force bouncing plate 4, internal diameter pulling force bouncing plate 4 outers are stuck on the interior step of external diameter lock lobe 5, locking pressure plate 9 screwed connections are on center bolt 10, locking pressure plate 9 is by thrust bearing 8 connecting external diameter thrust lock tubes 7, external diameter thrust lock tube 7 is sleeved on external diameter lock lobe 5 and is stuck on the outer step of external diameter lock lobe 5, center bolt 10 right-hand members are set with thrust plate 13, on inner core 1 outer wall, connect thrust base plate 3, between thrust base plate 3 and upper thrust plate 13, by distance rod 11, be connected, nut 14 screwed connections are on center bolt 10, between nut 14 and upper thrust plate 13, thrust bearing 12 is installed, on locking pressure plate 9 and nut 14, be equipped with the handle hole that can insert boosting-rod 15.
During use, with boosting-rod 15, insert the interior rotation of handle hole of locking pressure plate 9.Internal diameter pulling force bouncing plate 4 under tensions, because the internal diameter step of internal diameter lock lobe 6 is spacing by it, internal diameter pulling force bouncing plate 4 is butterfly plum blossom lobe bouncing plate structures, during under tension, outwards only have and rise, it is also petal-shaped forcing internal diameter lock lobe 6(internal diameter lock lobe 6) enlarged-diameter is stuck on the internal diameter of plastic bushing 2.External diameter thrust lock tube 7 promotion external diameter lock lobe 5(external diameter lock lobes 5 are also petal-shaped simultaneously), force external diameter lock lobe 5 internal diameters to shrink, stuck on the external diameter of plastic bushing 2.By the method for inside and outside clamping, plastic bushing 2 is jammed firmly.The moment of torsion of boosting-rod 15 is larger, and it is tighter that plastic bushing 2 is blocked.With the rope made of hemp, tie up on center bolt 10 and be pulled outwardly, center bolt 10 is moved with respect to inner core 1 is outer, drive plastic bushing 2 outwards to move together.Realize plastic bushing 2 object from pulling out in inner core 1 together with rock core.
If have the grains of sand that inner core 1 and plastic bushing 2 is stuck, still can not pull plastic bushing 2 by above way.At this moment add external agency, three distance rods 11 are inserted in the hole of thrust base plate 3 and are connected with inner core 1.With boosting-rod 15 rotating nuts 14, center bolt 10 is moved with respect to inner core 1 is outer, drive plastic bushing 2 outwards to move together.Realize the object that plastic bushing 2 is pulled out together with rock core from inner core 1.
Be understandable that, above about specific descriptions of the present invention, only for being described, the present invention is not limited to the described technical scheme of the embodiment of the present invention, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the present invention, to reach identical technique effect; As long as meet, use needs, all within protection scope of the present invention.
