Abstract
The invention relates to a compound rotary drilling rig drilling mechanism which is provided with a long tube shape coat drill pipe of which the upper part is provided with a mud discharging port. The lower end of the coat drill pipe is fixedly connected with a heavy-calibre drill by a flange bolt; a spiral drill pipe coaxially rotating is arranged in the coat drill pipe; the bottom end of the rotary drill pipe is connected with a guiding drill; the coat drill pipe and the spiral drill pipe are in sectioned connection structure; two ends of the coat drill pipe and the spiral drill pipe are respectively provided with a quick-change connector capable of quickly splicing and installing; the upper part of the spiral drill pipe is connected with a motor; and meanwhile, the motor is meshed and connected with the gear on the coat drill pipe in a driving mode. The compound rotary drilling rig drilling mechanism has the construction function of a common drilling mechanism, can conveniently adjust the length of the drill pipe and carry out heavy-calibre drilling construction, can pump drilled mud and sand out of the drill pipe, effectively improves progress of works, solves the problem of poor stability caused by an over-high rotary drilling rig and is convenient to transport the rotary drilling rig.
Description
Technical field
The present invention relates to a kind of rig of rotary drilling rig, specifically a kind of compound rotary drilling rig drilling mechanism.
Background technology
At present, rotary drilling rig has become the main pile foundation pore-forming instrument in countries in the world railway, highway, water conservancy, the construction of worker China Democratic National Construction Association, but since the bore diameter of this rig generally between 400-600mm, also just powerless for bigbore boring.And the drilling rod of rig is long, and the stability of rig can be subjected to very big influence, has limited the safe handling of equipment, can't satisfy the needs of engineering construction.And drill bit revolves and digs in the process of boring soil, when filling earth sand material in the drill bit, outside the drill bit lifting need being portalled, the earth sand material in it is poured over cubic metre of earth car or ground, and is very inconvenient, influenced operating efficiency.
Summary of the invention
In order to improve the functional of existing rotary drilling rig, the present invention proposes a kind of compound rotary drilling rig drilling mechanism, this mechanism not only has the construction function of general borehole drill construction, but also can conveniently regulate the length of drilling rod and carry out the big diameter borehole construction, and the silt particle that gets out directly can be discharged outside the drilling rod automatically, improved effect greatly, improved programming effectively, solve the problem of the too high caused less stable of Spiral digging machine, also made things convenient for the transportation of this rig.
The technical solution adopted for the present invention to solve the technical problems is: this a kind of compound rotary drilling rig drilling mechanism comprises starter, large diameter bit, auger stem, overcoat drilling rod, mud mouth and motor; There is the overcoat drilling rod of a long barrel shape in this mechanism, and this overcoat drilling rod top is provided with mud mouth; This overcoat drilling rod lower end has the large diameter bit of revolving dig blade by the fixedly connected bottom of flange bolt, and this drill bit can be changed easily according to different boring demands; This overcoat drilling rod inside is provided with the auger stem of coaxial rotation; This auger stem bottom is connected with starter; This overcoat drilling rod and auger stem are a kind of sectional section connection type structure, the two ends of overcoat drilling rod and auger stem are respectively equipped with the hydraulic quick coupler that can peg graft fast and install, can be according to the construction demand, regulate the length of overcoat drilling rod easily, in addition, owing to be the structure of section connection type, make the dismounting of drilling rod more convenient, safety; This auger stem top, connect the motor that promising this auger stem provides operation power by gears engaged, simultaneously, this motor is connected with meshed transmission gear on the overcoat drilling rod by idler, make the concentric rotation in the other direction of auger stem and overcoat drilling rod, and the silt that brill can be dug down is promoted to the discharge of overcoat drilling rod mud mouth.
The invention has the beneficial effects as follows: this a kind of compound rotary drilling rig drilling mechanism, the construction function that not only has general borehole drill construction, but also can conveniently regulate the length of drilling rod and carry out the big diameter borehole construction, and can directly extract out the silt particle that gets out outside the drilling rod, improved programming effectively, solve the problem of the too high caused less stable of Spiral digging machine, made things convenient for the transportation of this rig.
