Abstract
A novel drilling tool joint comprises an upper joint body and a lower joint body, wherein the end parts of the upper joint body and the lower joint body are provided with half screw threads which are matched with each other; the transmission key sleeve is sleeved outside the upper joint body and the lower joint body, and an axial key and a groove which are mutually matched in a sliding way are arranged between the inner side of the transmission key sleeve and the outer sides of the upper joint body and the lower joint body; the upper joint body is provided with a radial elastic telescopic positioning pin, the outer end of the upper joint body extends out of the surface of the joint body, and the transmission key sleeve is provided with a positioning hole corresponding to the positioning pin. The utility model has the advantages that: when the upper joint is aligned and inserted into the lower joint to rotate 90 degrees, the lower transmission key sleeve is inserted, the lock pin is automatically locked and positioned, and all connection work is finished. Therefore, the large torque is not needed for connection and disconnection, the time is saved, the screw thread is protected, and the service life of the screw thread of the drilling tool is prolonged. No matter the rotation is reversed or positive, the bearing and the torsion as well as the sealing are very reliable. Because the upper and lower joint each other has the effect of rightting, has the effect of preventing breaking, and the destructive action that the jump bored can also be alleviated to a certain extent to its structure, if the card brill accident has taken place, this structure has the condition that the explosion pine was buckled.
Description
Technical field
The utility model relates to petroleum natural gas exploration equipment, particularly a kind of novel tool joint.
Background technology
At present, drilling tool all is that the different taperings circles of employing are buckled, the side buckles or ladder lock both at home and abroad, divides left and right sides spinner again.Solve tensile load by screw thread.Screw thread one end has step, and the box and pin step pushes mutually, solves sealing and transfer torque problem.Its shortcoming is need very big tightening torque, prevents to get loose on the one hand, guarantees sealing on the other hand.Big moment of torsion has quickened the damage of screw thread, also causes the difficulty of shackle.In case screw thread gets loose, can cause the drilling tool well that falls, perhaps can form the accident that fractures of screw thread.If in construction, occur the drilling tool backward rotation for a certain reason, also can cause to hold to detain to come off.During last shackle, a button, wearing and tearing cause the damage of screw thread to be difficult to avoid.Not only time-consuming but also require great effort when unloading drilling tool.
Summary of the invention
The purpose of this utility model just provide a kind of easy to loading and unloading, long novel tool joint of little, life-span can not get loose, wear and tear.
The technical solution of the utility model is: comprise top connection body and lower contact body, the half spiral shell button that cooperatively interacts is arranged the end of fittings body up and down at this; Also comprise being placed in the outer driving key cover of fittings body up and down between its inboard and described fittings body up and down outside axial bond and the groove that is slidingly matched mutually arranged; At the top connection body radial elastic alignment pin that stretches is arranged, the fittings body surface is stretched out in its outer end, puts the locating hole corresponding with above-mentioned alignment pin at described driving key.
There is a reducing upper end at described driving key cover, is with helical spring within it and between the external side switch of top connection.
Between described alignment pin and the top connection body, be equipped with sealing ring between top connection body and the lower contact body.
The utility model advantage is: when connecting top connection is aligned the insertion lower contact and rotate 90 degree, go into underdrive key cover, lock pin automatic locking location all connects work and just finishes.Do not need high pulling torque so unload, save time, the protection screw thread prolongs the drilling tool screw thread life-span.No matter rotate anyway, bear bearing torque and seal all very reliable.Because effect is set upright in last lower contact mutually, and anti-breaking effect is arranged, its structure can also can be alleviated the destruction of bouncing of drilling tool to a certain extent, if lock of tool drilling has taken place, this structure has the condition of breakouting pack of dynamite.
Description of drawings
Fig. 1 is the cross-sectional schematic of the utility model structure;
Fig. 2 is the enlarged drawing of A portion among Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises top connection body 1 and lower contact body 8, and the half spiral shell button 6 that cooperatively interacts is arranged in their end; Be with driving key cover 3 outside the fittings body up and down, there is axial keyway 5 its inboard, and the groove that is slidingly matched with above-mentioned keyway 5 is arranged in the outside of lower contact body 8; At top connection body 1 the radial elastic alignment pin 4 that stretches is arranged, the top connection external surface is stretched out in its outer end.The locating hole 31 corresponding with above-mentioned alignment pin 4 arranged on described driving key cover 3.
There is a reducing upper end at described driving key cover 3, is with helical spring 2 within it and between the top connection body 1 outer side switch.
Between described alignment pin 4 and the top connection body 1, be equipped with O type or y-type seal ring 7 between top connection body 1 and the lower contact body 8.
The elastic telescopic function of the alignment pin 4 of this embodiment is enclosed within outside the shank 42 by helical spring 41 and realizes.
When using the utility model, top connection body 1 is inserted in the lower contact body 8, aim at fixed setting and turn 90 degrees, make 6 engagements of half spiral shell button.Inwardly press alignment pin 4 with a metal bar, after alignment pin is pressed into, presses down driving key cover 3 and put in place, alignment pin 4 automatic lockings, at this moment, spring 2 is compressed, and sealing ring 7 puts in place, and half button of fittings body aligns engagement up and down, and work is all finished.Handling rotation to the key tool all can be carried out safely.
The utility model has been realized following function:
1, do not need with detaining on the big moment, pin thread gets final product going into box rotation 90 degree.
2, do not need box and pin step jam-packed to guarantee sealing, but seal with O shape circle and Y shape circle, voltage endurance capability is strong.
3, do not need step jam-packed transfer torque, but by sliding sleeve key transfer torque, twisting resistance is big.
4, do not have the possibility of threading off, fractureing after releasing, but screw thread is subjected to key control, key not slide fastener does not take off, and key is antitorque, screw thread tension safety factor is very big.
5, not existing anyway, commentaries on classics may cause the dropout phenomenon.
6, because shackle on the moment greatly, so screw thread damages slowly long service life.
7, the button that do not pause in the time of can realizing shackle does not grind button.
8, male and female is buckled with mutual centralizing function, and anti-breaking effect is arranged.
9, time of unloading fast, save operational motion and physical demands.
10, drilling tool has automatic positioning action, and orientation is easy to remember the orientation of drill bit and underground work when boring down.
