Abstract
The invention relates to a self-locking and unlocking device for the sampling pipe joints of hollow stems for soft formations. The bottom of the metal hollow stem female joint is symmetrically provided with slider sockets, movable locking sliders are mounted in the slider sockets, one end of each locking slider is extended out of the metal hollow stem female joint, the other end of each locking slider is connected with one end of a slider spring in the slider socket, and the other end of each slider spring is fixed on the inner wall of the slider socket. The end surface of the metal hollow stem male joint is symmetrically provided with bolt sockets, bolts are limited in the bolt sockets, one end of each bolt is fixed on a bolt spring, and the other end of each bolt is extended out of the end surface of the metal hollow stem male joint. The self-locking and unlocking device can prevent a drilling rig from being unthreaded during reverse rotation, and meanwhile, the drill stem can be conveniently replaced.
Description
Technical field
The invention belongs to the underwater drilling technical field, relate to a kind of self-locking and tripper of incompetent bed hollow drill probe tube interface.
Background technology
The core bit that is used for incompetent beds such as soil, deposit, mud bores like major works, adopts hollow drill (sleeve pipe of holding concurrently) to get core usually, and drilling-rod external wall is threaded, so that downlink drive power is provided.When drilling tool was descending, the drilling rod connecting portion can form self-tightening because of the design of thread rotary orientation.Carrying when boring, the frictional force of deposit, mud and viscous force make and carry that to bore resistance very big, need when carrying brill, oppositely select drilling rod, being that drilling rod provides up power by screw thread.During the drilling rod reverse rotation, interface thread can be unscrewed, and therefore drilling rod may get loose and drop.Self-locking device is set prevents getting loose of when the drilling tool direction is rotated interface.For making the boring coring operation realize automation and unmanned, also be very important with self-locking mechanism and the supporting release mechanism of manipulator operation.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of self-locking and tripper of incompetent bed hollow drill probe tube interface is provided.The present invention includes metal hollow tool joint box, sliding block spring, lock slider, latch, latch spring and metal hollow fillet of tool joint pins.
Metal hollow tool joint box bottom symmetry has slide block slot; Movable lock slider is housed in the slide block slot; One end of lock slider stretches out outside the metal hollow tool joint box, and an end of the sliding block spring in the other end and the slide block slot is connected, and the other end of sliding block spring and slide block slot inwall are fixed.
Symmetry has the latch groove on the end face of metal hollow fillet of tool joint pins, and latch is limited in the latch groove, and an end and the latch spring of latch are fixed, and the other end stretches out the end face of metal hollow fillet of tool joint pins.
The latch in the described slide block slot and the corresponding setting of latch groove, latch groove and the inclined-plane side contacts of the lock slider in the slide block slot.
Described metal hollow tool joint box and described metal hollow fillet of tool joint pins pass through threaded engagement.
The internal diameter of whole metal hollow drilling rod is 40～200 millimeters, 5～20 millimeters of wall thickness, and 2～5 meters of single-unit length, outer wall has external screw thread.
Beneficial effect of the present invention: the present invention can prevent drilling tool the getting loose of interface when reverse rotation, makes things convenient for the replacing of drilling rod simultaneously.
Description of drawings
Fig. 1 is apparatus of the present invention structural representation;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is the partial enlarged drawing of apparatus of the present invention;
Among the figure: metal hollow tool joint box 1, sliding block spring 2, lock slider 3, latch 4, latch spring 5, metal hollow fillet of tool joint pins 6.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
Like Fig. 1, shown in 2 and 3, the self-locking and the tripper of incompetent bed hollow drill probe tube interface comprise metal hollow tool joint box 1, sliding block spring 2, lock slider 3, latch 4, latch spring 5 and metal hollow fillet of tool joint pins 6.
Metal hollow tool joint box bottom symmetry has slide block slot; But the lock slider of translation is housed in the slide block slot; One end of lock slider stretches out metal hollow tool joint box outer (being convenient to the operation of manipulator); One end of the sliding block spring in the other end and the slide block slot is connected, and the other end of sliding block spring and slide block slot inwall are fixed.
Symmetry has the latch groove on the end face of metal hollow fillet of tool joint pins, this end face and female joint pig; Latch is limited in the latch groove, and an end and the latch spring of latch are fixed, and the other end stretches out the end face of metal hollow fillet of tool joint pins.
Slide block slot and the corresponding setting of latch groove guarantee that the female joint of metal hollow drill screws in behind the metal hollow fillet of tool joint pins both work that can cooperatively interact, the inclined-plane side contacts of the lock slider that the latch in the latch groove and slide block slot are interior; Latch head among the embodiment is that hemispherical, such design is beneficial to itself and the contacting of the inclined-plane of lock slider, and makes that moving of lock slider is more steady.
Metal hollow tool joint box and metal hollow fillet of tool joint pins have so just been accomplished the splicing between the drilling rod through threaded engagement.
The step of the method for using of apparatus of the present invention is following:
1) at the probing well head, the lock slider in the metal hollow tool joint box is pinned inward, fixed the metal hollow tool joint box with the bank head machinery hand simultaneously with the bank head machinery hand.
2) with the bank head machinery hand metal hollow tool joint box is connected with metal threaded hollow drill male joint; The two revolve 90 the degree tighten; The release mechanism hand, because the elastic force effect of sliding block spring, lock slider ejects; Because the elastic force effect of latch spring, latch is headed in the slide block slot of metal hollow tool joint box;
3) the incompetent bed special drilling machine begins probing, and the metal hollow drilling rod is rotated down motion, passes through the tapered tread transfer torque between the drilling rod;
4) probing of incompetent bed special drilling machine finishes to reclaim drilling rod, and the metal hollow drilling rod is done the reverse rotation campaign, because the elastic force effect of latch spring, bullet on the latch prevents to get loose between the drilling rod through latch between the drilling rod.
5) bank head machinery is manual does; With the bank head machinery hand lock slider in the metal hollow tool joint box is pinned inward; The two reverse rotation 90 degree unclamps metal hollow tool joint box and metal hollow fillet of tool joint pins, and drilling rod is put into assigned address; The probing of metal hollow drilling rod is accomplished, and gets into the armed state of operation next time.
