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 sampling pipe joints of hollow stems for soft formations.
Background technology
The core bit that is used for the incompetent beds such as soil, deposit, mud bores as major works, usually adopts hollow drill (sleeve pipe of holding concurrently) to get core, and drilling-rod external wall is threaded, in order to 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 large, need to oppositely select drilling rod when carrying brill, to provide up power by screw thread as drilling rod.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 drilling tool direction rotation 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 deficiencies in the prior art, a kind of self-locking and tripper of sampling pipe joints of hollow stems for soft formations 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 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 slide block slot is connected, and the other end of sliding block spring and slide block slot inwall are fixed.
On the end face of metal hollow fillet of tool joint pins, symmetry has the latch groove, 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.
Latch in described slide block slot and the corresponding setting of latch groove, latch groove and the inclined-plane side contacts of the lock slider in 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 that drilling tool from when reverse rotation the getting loose of interface, facilitating 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;
In 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
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Fig. 1,2 and 3, the self-locking of sampling pipe joints of hollow stems for soft formations and tripper 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 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 slide block slot is connected, and the other end of sliding block spring and slide block slot inwall are fixed.
On the end face of metal hollow fillet of tool joint pins, symmetry has the latch groove, and this end face and female joint bottom connection touch; 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 after 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 in embodiment is that hemispherical, such design is beneficial to itself and the contacting of the inclined-plane of lock slider, and makes the movement of lock slider more steady.
Metal hollow tool joint box and metal hollow fillet of tool joint pins have so just been completed the splicing between drilling rod by threaded engagement.
The step of the using method of apparatus of the present invention is as follows:
1) at the probing well head, with the bank head machinery hand, 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.
2) with the bank head machinery hand, the metal hollow tool joint box is connected with metal threaded hollow drill male joint, both revolving 90 degree tightens, the release mechanism hand, elastic force effect due to sliding block spring, lock slider ejects, due to 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 transmitting torque between drilling rod;
4) probing of incompetent bed special drilling machine finishes Recycling of drill rod, and the metal hollow drilling rod is done the reverse rotation motion, and due to the elastic force effect of latch spring, bullet on latch prevents from getting loose between drilling rod by latch between drilling rod.
5) bank head machinery is manual does, with the bank head machinery hand, the lock slider in the metal hollow tool joint box is pinned inward, both counter-rotate 90 degree, metal hollow tool joint box and metal hollow fillet of tool joint pins are unclamped, drilling rod is put into assigned address, the probing of metal hollow drilling rod is completed, and enters the armed state of operation next time.
