Abstract
The invention relates to a threaded drill bit with a rotatable ring and a method for using the same. The threaded drill bit comprises the rotatable ring, a hollow drill bit, a clamp and a spring, an external thread is arranged outside the hollow drill bit, the rotatable ring capable of freely rotating is arranged on the upper portion of the hollow drill bit, an external thread is also arranged outside the rotatable ring, the clamp is fixedly arranged inside the rotatable ring and connected with the inner wall of the rotatable ring through a spring, and the rotatable ring, the hollow drill bit, the clamp and the spring are coaxial. The threaded drill bit is used with a rotary soft formation drill coring lining pipe, and mechanical force can be provided for rotation of a rotary table of a core leak preventer when a rotary sediment core drill bit is used for coring. When the drill bit rotates, a blade can retract into a coring port of the core leak preventer so that sediment smoothly enters a corer, and the blade less contacts with sediment and is not easy to be abraded. When in coring, the blade synchronously rotates, the coring port is placed at the smallest position, a core is cut off, completeness of the core is guaranteed, and the core is prevented from slipping off.
Description
Technical field
The invention belongs to underwater drilling technical field, relate to a kind of threaded drill bit with rotatable ring and using method thereof.
Background technology
Rotary (all kinds of rig) and penetrated (Churn drill and gravity piston type sampler) two large classes that deposit core bit is divided into.Penetrated corer arranges petal type anti-slip device in lower port conventionally, to prevent deposit landing and the leakage of corer inside.Petal type anti-slip device can not be applicable to rotary core bit, and when drilling tool rotates, petal can hinder deposit to enter corer, and the rotation friction of deposit and petal also can damage petal.The anti-slip device of rotary deposit core bit core need adopt rotation form to realize the variation in aperture.Rotatable ring on drill bit can provide mechanical force for the rotation dial rotation of core leak-proof device.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of threaded drill bit with rotatable ring and using method thereof are provided.
Threaded drill bit with rotatable ring comprises rotatable ring, hollow boring bit, jig and spring, hollow boring bit outside is with external screw thread, one section of rotatable ring that can rotate freely is arranged at the top of hollow boring bit, rotatable ring outside is also with external screw thread, is fixedly installed jig, jig is connected with rotatable ring inwall by spring in rotatable ring; Described rotatable ring, hollow boring bit, jig and spring coaxially arrange.Described jig is convex structure.
This threaded drill bit using method comprises the steps:
1) while using, core leak-proof device is screwed in to the lower end of getting core bushing pipe, is inserted in the jig of hollow boring bit upper end, under the effect of spring, jig is held the rotary disk of core leak-proof device.
2) while creeping into, the rotatable ring on drill bit is rotated under its externally threaded drive, and the rotary disk of jig drive core leak-proof device is forward rotation together, makes the blade of core leak-proof device inside in compression aperture maximum position.
3) get before core, first rotate backward drilling tool, rotatable ring on drill bit is rotated under its externally threaded drive, jig drives the rotary disk of core leak-proof device to rotate backward together, make the blade of core leak-proof device inside in compression aperture minimum position, cut off core, and the landing that prevents from getting core process core.
The present invention and lining tube of rotary soft formation drilling rig are got core bushing pipe and are supported the use, and are applicable to rotary core bit, when using rotary deposit core bit to get core, can provide mechanical force for the rotation dial rotation of core leak-proof device.When drilling tool rotates, blade can shrink in core leak-proof device is got core mouth, makes the smooth and easy corer that enters of deposit, and blade contacts few with deposit, not easy to wear; While getting core, blade synchronously rotates, and makes to get core mouth in minimum position, cuts off rock core, guarantees that rock core is complete, and prevents rock core landing.
The present invention is suitable for the boring coring of all kinds of incompetent beds, as deposit, soil, frozen soil, ice, is particularly suitable for sedimental boring coring.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Fig. 1, shown in Fig. 2, with the hollow boring bit of rotatable ring, comprise rotatable ring 3, hollow boring bit 4, jig 1, spring 2.Hollow boring bit 4 outsides are with external screw thread, and one section of rotatable ring that can rotate freely 3 is arranged at the top of hollow boring bit 4.In rotatable ring 3, be fixedly installed jig 1, spring 2.
Described hollow boring bit 4 outer walls are with external screw thread, hollow boring bit 4 both ends open, and one of them open end is for getting core mouth, and another open end coordinates with the through hole of rotatable ring 3.One section of rotatable ring that can rotate freely 3 is arranged at hollow boring bit 4 tops.
In described rotatable ring 3, be fixedly installed jig 1, spring 2.Rotatable ring 3 bottoms are connected with hollow boring bit 4, can rotate freely, and top coordinates with core leak-proof device 5.
Described jig 1 is convex structure, be fixed in rotatable ring 3, and with rotatable ring 3 in the middle of have spring 2 to be separated by, block the rotary disk of core leak-proof device 5 when using.
It is middle with jig 1 that described spring 2 is fixedly installed on rotatable ring 3, for the power of jig 1 clamping is provided.
As Fig. 3, shown in Fig. 4, the step of the using method of apparatus of the present invention is as follows:
1) while using, core leak-proof device 5 is screwed in to the lower end of getting core bushing pipe, is inserted in the jig 1 of hollow boring bit upper end, under the effect of spring 2, jig 1 is held the rotary disk of core leak-proof device 5.
2) rotatable ring 3 while creeping on drill bit is rotated under its externally threaded drive, and the rotary disk of jig 1 drive rock core leak-proof device 5 is forward rotation together, makes the blade of rock core leak-proof device 5 inside in compression aperture maximum position;
3) get before core, first rotate backward drilling tool, rotatable ring 3 on drill bit is rotated under its externally threaded drive, jig 1 drives the rotary disk of core leak-proof device 5 to rotate backward together, make the blade of core leak-proof device 5 inside in compression aperture minimum position, cut off rock core, and the landing that prevents from getting core process core.
