Abstract
The utility model relates to a threaded drill bit with a rotating ring. The threaded drill bit with the rotating ring comprises a rotating ring, a hollow drill bit, a clamp and a spring, the outside of the hollow drill bit is provided with outer threads, the upper part of the hollow drill bit is provided with a section of rotating ring which can rotate freely, the outside of the rotating ring is also provided with outer threads, the clamp is fixedly arranged inside the rotating ring, and the clamp is connected with the inner wall of the rotating ring through a spring; and the rotating ring, the hollow drill bit, the clamp and the spring are coaxially arranged. The threaded drill bit is matched with a rotating-type flexible rock layer drill tool core drilling bushing to use, when a rotating-type precipitate core drilling tool is used for drilling a core, mechanical force can be provided for the rotation of a rotating turntable of a rock core leakage preventing device. When the drilling tool rotates, a knife blade can be retracted into a rock core leakage preventing device core drilling port, so that precipitate can smoothly enter the core drilling device, the contact between the knife blade and the precipitate is less, and the knife blade is not easy to abrade; and when the drill bit is used for drilling the core, the knife blade rotates synchronously, so that the core drilling port stays on a minimal position, the rock core is cut off, the completeness of the rock core can be guaranteed, and the rock core can be prevented from dropping off.
Description
Technical field
The utility model belongs to the underwater drilling technical field, relates to a kind of screw-type drill bit that has rotatable ring.
Background technology
Rotary (all kinds of rig) and penetrated (Churn drill and gravity piston type sampler) two big classes that the deposit core bit is divided into.The penetrated corer is provided with the petal type anti-slip device in lower port usually, with deposit landing and the leakage that prevents that corer is inner.The petal type anti-slip device can not be applicable to rotary core bit, and when drilling tool rotated, petal can hinder deposit to get into 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 the rotation form to realize the variation in aperture.Rotatable ring on the drill bit can provide mechanical force for the rotation dial rotation of core leak-proof device.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of screw-type drill bit and method for using thereof that has rotatable ring is provided.
The screw-type drill bit that has rotatable ring comprises rotatable ring, hollow boring bit, jig and spring; The hollow boring bit outside has external screw thread; One section rotatable ring that can rotate freely is arranged at the top of hollow boring bit; The rotatable ring outside also has external screw thread, is set with jig, jig in the rotatable ring and is connected with the rotatable ring inwall through spring; The coaxial setting of described rotatable ring, hollow boring bit, jig and spring.Described jig is a convex structure.
The utility model and rotary incompetent bed drilling tool are got the supporting use of core bushing pipe, are applicable to rotary core bit, when using rotary deposit core bit to get core, can mechanical force be provided for the rotation dial rotation of core leak-proof device.When drilling tool rotated, blade can shrink in the core leak-proof device is got the core mouth, made the smooth and easy entering corer of deposit, and blade contacts few with deposit, not easy to wear; When getting core, blade rotates synchronously, makes to get the core mouth and be in minimum position, cuts off core, guarantees that core is complete, and prevents the core landing.
The utility model is suitable for the boring coring of all kinds of incompetent beds, like deposit, soil, frozen soil, ice, is particularly suitable for sedimental boring coring.
Description of drawings
Fig. 1 is the utility model sectional view;
Fig. 2 is the utility model vertical view;
Fig. 3 is the relative position figure of the utility model jig and core leak-proof device before work;
Fig. 4 is the rotary disk relative position figure of the utility model jig chucking core leak-proof device when work;
Among the figure: 1. jig, 2. spring, 3. rotatable ring, 4. hollow boring bit, 5. core leak-proof device.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, shown in Figure 2, the hollow boring bit that has rotatable ring comprises rotatable ring 3, hollow boring bit 4, jig 1, spring 2.Hollow boring bit 4 outsides have external screw thread, and one section rotatable ring that can rotate freely 3 is arranged at the top of hollow boring bit 4.Be set with jig 1, spring 2 in the rotatable ring 3.
Described hollow boring bit 4 outer walls have external screw thread, hollow boring bit 4 both ends open, and one of them open end is for getting the core mouth, and another open end cooperates with the through hole of rotatable ring 3.One section rotatable ring that can rotate freely 3 is arranged at hollow boring bit 4 tops.
Be set with jig 1, spring 2 in the described rotatable ring 3.Rotatable ring 3 bottoms are connected with hollow boring bit 4, can rotate freely, and top cooperates with core leak-proof device 5.
Described jig 1 is a convex structure, is fixed in the rotatable ring 3, and has spring 2 to be separated by with rotatable ring 3 centres, blocks the rotary disk of core leak-proof device 5 when being used to use.
It is middle with jig 1 that described spring 2 is fixedly installed on rotatable ring 3, is used to provide the power of jig 1 chucking.
Like Fig. 3, shown in Figure 4, the step of the method for using of the utility model device is following:
When 1) using core leak-proof device 5 is screwed in the lower end of getting the 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.
3) get core before; Elder generation's backward rotation drilling tool; Rotatable ring 3 on the drill bit is rotated under its externally threaded drive, and the rotary disk of jig 1 drive core leak-proof device 5 is backward rotation together, makes core leak-proof device 5 inner blades be in compression aperture minimum position; Cut off core, and the landing that prevents to get core process core.
