It is provided with the first chamfering 16, the second chamfering 17 is provided on the outer wall at 1 lower port of guide shoe.
To realize the normal recycling of throw in catcher, it just must have a corresponding cylindric unlocking device, setting
First chamfering 16 then can be convenient unlocking device and enter the outside of left claw body 3 and right corpus unguis 4 and squeeze them, Jin Ershi
Now to the unlock of throw in catcher, and the setting of the second chamfering 17 can make guide shoe 1 more smoothly slide to fishing spear 15 along drilling tool.
As shown in attached drawing 1,2, at least provided with one in 2 cylindrical portion of throw in catcher ontology of 8 lower section of left long hole 6 or right long hole
The mud through-hole 18 being along the circumferential direction distributed.
In downlink, mud can flow out throw in catcher ontology 2 in this way out of mud through-hole 18, reduce friction in down stroke, together
When can be avoided throw in catcher ontology 2 in uplink, generate swabbing, influence the taking-up process of throw in catcher.
The utility model is further described below with reference to embodiment two and attached drawing:
Embodiment two: as shown in attached drawing 1,3, a kind of unlock that the throw in catcher with above-mentioned wireless drilling measurer matches
Device, unlocking device include unlocking device ontology 19, card 20, and unlocking device ontology 19 is cylindrical, and unlocking device ontology 19 can be set in throwing
It fishes out the upper outside of device ontology 2 and its inner wall can squeeze left claw body 3 and the protrusion 13 on right corpus unguis 4, the side of unlocking device ontology 19
A slit 21 is provided on wall, slit 21 runs through the upper and lower end face of unlocking device ontology 19, the unlocking device sheet in 21 side of slit
Slit 21 is blocked at least provided with being removably installed together across the card slot 22 of slit 21, in card slot 22 on 19 lateral wall of body
Card 20.
When wireless drilling measurer is after shaft bottom is transferred in maintenance by throw in catcher again and successfully sits key, in order to recycle
Throw in catcher needs to be unlocked throw in catcher with unlocking device, and unlocking device ontology 19 is set in the outer of twisted rope using slit 21
It side can be in the unlocking device sheet of 21 side of slit in order to preferably avoid twisted rope from skidding off from the slit 21 on unlocking device ontology 19
The card slot 22 of upper, middle and lower three is set on 19 lateral wall of body, then slit 21 is blocked with card 20, card 20 can pass through
Screw is fixedly connected in corresponding card slot 22, and unlocking device is discharged in well head then, is allowed to do freely falling body fortune along twisted rope
Dynamic, when falling on the position of throw in catcher under unlocking device, unlocking device impacts throw in catcher using the kinetic energy of its own, and makes to solve
Lock device ontology 19 is sleeved on the outside of throw in catcher ontology 2, and the inner wall of unlocking device ontology 19 will squeeze left claw body 3 and right pawl at this time
Protrusion 13 on body 4, so that deep gouge 5 and right 7 contract of deep gouge to the left are distinguished in the upper end of left claw body 3 and right corpus unguis 4, it is same with this
When, left claw body 3 and the lower end of right corpus unguis 4 will tilt therewith, and then pawl 14 is made to be detached from beating on wireless drilling measurer
Fish out lance 15, finally make unlocking device achieve the purpose that unlock throw in catcher, final step is exactly to promote twisted rope, so that it may throw in catcher and
Unlocking device takes out from shaft bottom simultaneously, and unlocking device structure and application method are all very simple, Neng Goupei good to the unlock effect of throw in catcher
Conjunction throw in catcher efficiently completes wireless drilling measurer and mentions, puts operation, has very strong practicability.
Above-mentioned unlocking device can be made further optimization and/or improvements according to actual needs:
As shown in attached drawing 1,3, it is provided with card on the downside inner wall of above-mentioned unlocking device ontology 19 and puts left claw body 3 and right corpus unguis 4
Upper raised 13 limiting groove 23.
It in this way can be to avoid unlocking device ontology 19 in impact extruded left claw body 3 and right corpus unguis 4, due to the elasticity of torsional spring 11
Effect, unlocking device ontology 19 is ejected, and then leads to the situation of throw in catcher unlock failure.
The above technical characteristic constitutes the most preferred embodiment of the utility model, with stronger adaptability and best implementation
Effect can increase and decrease non-essential technical characteristic, according to actual needs to meet the needs of different situations.
