Abstract
The utility model relates to geological mapping technical field, specifically relates to a kind of probing follow-up casing bit when soft stratum and the serious stratum of spillage are drilled.Arrange sleeve pipe between drill bit described in the utility model and drilling rod, described drilling rod is fixedly installed drilling rod outer oblique gear with drill bit junction, described internal surface of sleeve pipe lower end is fixedly installed sleeve pipe internal helical gear; Drilling rod outer oblique gear creeps into phase with sleeve pipe internal helical gear at drill bit and engages mutually.The utility model has following beneficial effect: the technical problem that the utility model solves is between drill bit and drilling rod, adopt one group of internal helical gear to be connected, and drilling rod drives rotation of sleeve while driving drill bit to carry out creeping into, and reaches the object of setting of casing retaining wall.The utility model one probing follow-up casing bit structure is simple, easy to use, can effectively solve in the process that driller does run into soft stratum or lost circulation is serious, easily collapse hole stratum time supporting to hole wall.
Description
Technical field
The utility model relates to geological mapping technical field, specifically relates to a kind of probing follow-up casing bit when soft stratum and the serious stratum of spillage are drilled.
Background technology
Usually in the process of carrying out probing work, run into soft stratum or lost circulation serious, easily collapse hole stratum time, usually adopt driving into type sleeve pipe to carry out supporting to hole wall, ensure completing smoothly of probing work.This method wastes time and energy, and it is large to play setting of casing difficulty, and inefficiency.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency existed for prior art, provides a kind of probing follow-up casing bit when soft stratum and the serious stratum of spillage are drilled.
The utility model one probing follow-up casing bit comprises drilling rod, drill bit, and arrange sleeve pipe between described drill bit and drilling rod, described drilling rod is fixedly installed drilling rod outer oblique gear with drill bit junction, described internal surface of sleeve pipe lower end is fixedly installed sleeve pipe internal helical gear; Drilling rod outer oblique gear creeps into phase with sleeve pipe internal helical gear at drill bit and engages mutually.
The utility model one probing follow-up casing bit has following beneficial effect compared with prior art: the technical problem that the utility model solves is between drill bit and drilling rod, adopt one group of internal helical gear, in drilling process, drilling rod drives drilling tool to creep into, be connected with one group of internal helical gear between drill bit and sleeve pipe, drilling rod drives rotation of sleeve while driving drill bit to carry out creeping into, and reaches the object of setting of casing retaining wall.
When after the full Rock And Soil of punching in drilling tool, carry out carrying brill, drill bit is engaged with sleeve pipe and is separated, and drilling tool is extracted out from inside pipe casing, back and forth carries out, and reaches the object of creeping into smoothly.
The utility model one probing follow-up casing bit structure is simple, easy to use, can effectively solve in the process that driller does run into soft stratum or lost circulation is serious, easily collapse hole stratum time supporting to hole wall.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model one probing follow-up casing bit technical scheme is further described.
As Figure 1-Figure 4, a kind of probing follow-up casing bit comprises drilling rod 1, drill bit 5, arrange sleeve pipe 2 between described drill bit 5 and drilling rod 1, described drilling rod 1 is fixedly installed drilling rod outer oblique gear 3 with drill bit 5 junction, described sleeve pipe 2 inwall lower end is fixedly installed sleeve pipe internal helical gear 4; Drilling rod outer oblique gear 3 and sleeve pipe internal helical gear 4 engage each other when drill bit 5 creeps into.
Further, described drilling rod 1 is connected with sleeve pipe 2 one group of helical gear, drives rotation of sleeve while drilling rod 1 drives drill bit 5 to carry out creeping into.
Further, in described sleeve pipe 2, the full Rock And Soil of punching carries out carrying brill, and drilling rod outer oblique gear 3 is engaged with sleeve pipe internal helical gear 4 and is separated, and drill bit 5 is extracted out in sleeve pipe 2.
Embodiment 1.
The technical problem that the utility model solves is between drill bit 5 and drilling rod 1, adopt one group of internal helical gear, in drilling process, drilling rod 1 drives drilling tool to creep into, be connected with one group of internal helical gear between drill bit 5 and sleeve pipe 2, drive sleeve pipe 2 to rotate while drilling rod 1 drives drill bit 5 to carry out creeping into, reach the object of setting of casing guard aperture wall.
When after the full Rock And Soil of punching in drilling tool, carry out carrying brill, drill bit 5 is engaged with sleeve pipe 2 helical gear and is separated, and drilling tool is extracted out from sleeve pipe 2 inside, back and forth carries out, reaches the object of creeping into smoothly.
