Technical field
The utility model is related to the technical fields that orienting cover takes out instrument, are a kind of orienting cover withdrawing devices.
Background technology
Orienting cover, which is located in oil drilling orientation joint and coordinates, sits the accessory that keyed MWD instruments use, main
Effect is support inclinometer, if be damaged when orienting cover uses at the scene, need to just be replaced in time, but since orientation connects
Head is during long-time service, and the problems such as corrosion, abrasion, deformation inevitably occur for inner wall, which results in it
Internal orienting cover can be abnormal difficult during replacement is taken out, time-consuming and laborious.
The content of the invention
The utility model provides a kind of orienting cover withdrawing device, overcomes the deficiency of the above-mentioned prior art, can be effective
It is inconvenient to solve the problems, such as that orientation joint interior orientation set takes out.
The technical solution of the utility model is realized by following measures：A kind of orienting cover withdrawing device includes screw thread
Bar, fixed operating sleeve are internally provided with axial mounting groove in the lower end of fixed operating sleeve, are provided on the side wall of mounting groove
First thread segment, is provided with the axial mounting hole connected with mounting groove in the upper end of fixed operating sleeve, on the inner wall of mounting hole
The second thread segment is provided with, on same straight line, threaded rod is set through mounting hole for the axis of mounting hole and the axis of mounting groove
It puts in fixed operating sleeve, threaded rod is threadedly coupled with mounting hole, and the upper end of threaded rod is equipped with up knob, the lower end of threaded rod
Top plate is provided on face.
Here is the further optimization and/or improvements to above-mentioned utility model technical solution：
A lower handle is at least installed on the outer wall of above-mentioned fixed operating sleeve.
Screw is set on the lower face of above-mentioned threaded rod, and top plate is mounted on by screw on threaded rod, and top plate can be with screw
It is circumferentially rotated for axis.
Above-mentioned second thread segment is API standard screw thread.
The utility model reasonable and compact in structure, by the pin end for being fixedly connected with the upper mounting groove of set and orientation joint
It is fixedly connected, then by up knob rotary screwing thread bar, threaded rod is made gradually to transfer, finally make top plate top pressure to the upper of orienting cover
On end face, at this time if continuing rotary screwing thread bar, it is possible to by orienting cover is steady, safety ejection orientation joint, entirely take out
Journey is simply, conveniently.
Description of the drawings
Attached drawing 1 is the main view schematic cross-sectional view of the best embodiment of the utility model.
Attached drawing 2 is connected to the main view schematic cross-sectional view on orientation joint for the best embodiment of the utility model.
Coding in attached drawing is respectively：1 is threaded rod, and 2 be fixed operating sleeve, and 3 be mounting groove, and 4 be mounting hole, and 5 be upper
Handle, 6 be top plate, and 7 be lower handle, and 8 be screw, and 9 be orientation joint, and 10 be orienting cover.
Specific embodiment
The utility model, can technical solution according to the present utility model and actual conditions from the limitation of following embodiments
Determine specific embodiment.
In the utility model, for ease of description, the description of the relative position relation of each component is according to specification
The Butut mode of attached drawing 1 is described, such as：The position relationship of upper and lower, left and right etc. is the Butut according to Figure of description 1
Direction is come definite.
The utility model is further described with reference to embodiment and attached drawing：
As shown in attached drawing 1,2, which includes threaded rod 1, fixed operating sleeve 2, in fixed operating sleeve 2
Lower end is internally provided with axial mounting groove 3, and the first thread segment is provided on the side wall of mounting groove 3, in fixed operating sleeve 2
Upper end is provided with the axial mounting hole 4 connected with mounting groove 3, and the second thread segment, mounting hole are provided on the inner wall of mounting hole 4
4 axis is with the axis of mounting groove 3 on same straight line, and threaded rod 1 is arranged on through mounting hole 4 in fixed operating sleeve 2, spiral shell
Rasp bar 1 is threadedly coupled with mounting hole 4, and the upper end of threaded rod 1 is equipped with up knob 5, and top plate is provided on the lower face of threaded rod 1
6.When in use, by the mounting groove 3 on fixed operating sleeve 2 by the utility model and the male end for being applied orientation joint 9
It is fixedly connected, then by the constantly rotary screwing thread bar 1 of up knob 5, threaded rod 1 is made also constantly to be lowered therewith, until spiral shell
6 top pressure of top plate on rasp bar 1 continues rotary screwing thread bar 1, just at this time to 10 upper surface of orienting cover being applied in orientation joint 9
Can orienting cover 10 is steady, safety ejection orientation joint 9, entire process of taking out is simple, conveniently, suitable for large-scale promotion.
Above-mentioned orienting cover withdrawing device can be made further optimization and/or improvements according to actual needs：
A lower handle 7 is at least installed with as shown in attached drawing 1,2, on the outer wall of fixed operating sleeve 2.It so can be square
Just the fixed operating sleeve 2 of the utility model is screwed, makes fixed operating sleeve 2 more easily with being applied orientation joint 9
It is threadedly coupled.
As shown in attached drawing 1,2, screw 8 is set, top plate 6 is mounted on threaded rod 1 by screw 8 on the lower face of threaded rod 1
On, top plate 6 can be circumferentially rotated with screw 8 for axis.People are in order to reach preferable pushing tow effect, it will usually change top plate 6
Into with the disk that is applied as 9 upper end access road diameter of orientation joint, if top plate 6 is fixedly mounted on threaded rod 1,
So when rotary screwing thread bar 1, larger frictional resistance is generated between the inner wall of 9 access road of 6 meeting of top plate and orientation joint, is unfavorable for
6 downlink of top plate is applied on orienting cover 10, and the top plate 6 of the utility model can run into resistance in a circumferential direction with screw 8 for axis
Power is free to rotate, substantially reduces frictional resistance.
As shown in attached drawing 1,2, the second thread segment is API standard screw thread.Because oil pipe its screw thread on present petroleum system
Standard is all largely to use API standard, and the mounting groove 3 on such the utility model fixed operating sleeve 2 can be directly with showing
There is the screw thread on orientation joint 9 to be connected, it is simple and convenient.
More than technical characteristic constitutes the most preferred embodiment of the utility model, with stronger adaptability and optimal implementation
Effect can increase and decrease non-essential technical characteristic, to meet the needs of different situations according to actual needs.
