Content of the invention
The technical problem to be solved in the present invention be provide a kind of can to turbogenerator well head carry out lifting operation with
Bore logging instrument turbogenerator fishing tool.
In order to solve above-mentioned technical problem, the present invention includes hanging cylinder, rotation preventing device, two locating rings, alignment pin and salvaging
Ring, a described upper end of hanging is connected with described salvaging ring, and lower end is formed with the rotatable convolution blocking turbogenerator upper end projection
Groove, described hanging is formed with a chute on drum outer wall, described rotation preventing device can slide up and down to and is arranged in described chute, two institutes
State locating ring and be accordingly set with up and down and be fixed in and hang to be limited in rotation preventing device in chute on drum outer wall, on described rotation preventing device also
It is connected with described alignment pin, the upper and lower ends of described alignment pin are respectively equipped with a clamping block, on the inwall of two described locating rings
It has been correspondingly formed a draw-in groove respectively up and down, clamping block wherein above can be locked at the card of locating ring above
To avoid rotation preventing device slide downward in groove, after rotation preventing device is subject to downward thrust, clamping block above departs from corresponding
Draw-in groove, rotation preventing device slide downward simultaneously makes its lower end be inserted in convolution groove so that the projection of turbogenerator upper end is locked in convolution
In groove, to realize hanging being fixedly connected of cylinder and turbogenerator, simultaneously underlying clamping block be locked at underlying fixed
To fix rotation preventing device in the draw-in groove of position ring.
Described rotation preventing device upper end is additionally provided with a plectrum being easy to promote rotation preventing device to slide up and down.
The invention has the beneficial effects as follows: the logging while drilling apparatus turbogenerator fishing tool that the present invention provides is arranged on turbine
On electromotor, alignment pin plays locked effect to rotation preventing device, prevents fishing tool from coming off, and turbogenerator can have been carried out in well head
Crane operation, has reached the function of lifting by crane turbogenerator in well head, and fishing tool Assembling is convenient, has very big practical meaning
Justice.
Brief description
Fig. 1 is the structural representation of logging while drilling apparatus turbogenerator fishing tool of the present invention；
Fig. 2 is arranged on the structural representation on turbogenerator for logging while drilling apparatus turbogenerator fishing tool of the present invention
Figure.
Specific embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description:
Referring to Fig. 1 and Fig. 2, the logging while drilling apparatus turbogenerator fishing tool of the present invention includes hanging cylinder 1, rotation preventing device 2, two
Individual locating ring 3, alignment pin 4 and salvaging ring 5.
Described cylinder 1 upper end of hanging is connected with described salvaging ring 5, and lower end is formed with convolution groove 11.Convolution groove 11 quantity is two,
And two convolution groove 11 centrosymmetry.Two convolution rotatable two projections blocking turbogenerator 6 upper end of groove 11.
Described hanging is formed with a chute on cylinder 1 outer wall, described rotation preventing device 2 can slide up and down to and is arranged on described chute
Interior, described rotation preventing device 2 upper end is provided with a plectrum 21, promotes rotation preventing device 2 to slide up and down manually in order to operator.Described in two
Locating ring is accordingly set with about 3 and is fixed in and hangs on cylinder 1 outer wall to be limited in rotation preventing device 2 in chute.On described rotation preventing device 2
Also be connected with described alignment pin 4, the upper and lower ends of described alignment pin 4 are respectively equipped with a clamping block, two described locating rings 3 interior
One draw-in groove has been correspondingly formed up and down respectively on wall.Wherein each described locating ring 3 be fixed on by two screws respectively described
Hang on cylinder 1, alignment pin 4 is fixed on rotation preventing device 2 by two screws.Described rotation preventing device 2 passes through described locating ring 3, described fixed
Position pin 4 hangs on cylinder 1 described in being fixed on.Each clamping block both sides on alignment pin 4 are each formed with groove, intermediate formation has opening,
During clamping block is inserted into corresponding draw-in groove, clamping block first shrinks to opening, when the groove of both sides enters into corresponding card
