Abstract
The utility model belongs to the field of drilling machines, and relates to a power head for a double-circulation drilling machine. The power head for the double-circulation drilling machine is mainly characterized in that a hydraulic motor serves as a power source, and is in transmission with a variable-speed gear in a gearbox; the variable-speed gear is meshed with a gear ring on a rotating plate in the gearbox; and the rotating plate is arranged on the upper portion of a drill pipe head, so that the power head is formed. The power head for the double-circulation drilling machine has the advantages that a drill pipe is prevented from being worn by the rotating plate, the weight of the drilling pipe head can be balanced, and the well drilling efficiency is improved.
Description
Technical field
The utility model belongs to rig field, relates to drill power head, specifically a kind of two circulation drilling machine unit head.
Background technology
Existing pair of circulation drilling machine, comprises pylon, water pump, slush pump, drilling rod, water tap, rotating disk, power drive mechanism etc., power drive mechanism passes to rig final drive shaft by the power of automobile engine, and through gearbox, universal drive shaft, to rotating disk, jar rod rotates, drill bit work; When water pump direct circulation running, mud enters slush pump through glue pipe under water pump effect, through the through down-hole of slurry sebific duct, water tap and drilling rod; When slush pump direct circulation running, drilling thing in down-hole is with mud under slush pump pumping, and through drilling rod, water tap, outside slurry sebific duct discharge well; Drilling rod is in lifting process, and water tap, drilling rod move up along the guide rail on pylon, and water tap drilling rod rises to pylon top, and when drilling rod declines, water tap is parked in the appropriate location of pylon.Because rotating disk is arranged on pylon bottom, rotating disk should rotate by jar rod, drilling rod is again through turntable lift, so in the process of drilling rod rotation, make drilling rod lifting produce resistance, not only affect drill bit operation, reduced drilling efficiency, and drilling rod and rotating disk wear and tear mutually, reduce the application life of work package.
Summary of the invention
Applicant, being engaged in for many years in the production and operating activities of rig, finds that existing pair of circulation drilling machine exists above-mentioned defect, improves through exploring, and object is to provide a kind of two circulation drilling machine unit head.Can solve the technical problem that existing pair of circulation drilling machine exists.
Technical solution adopted in the utility model is a kind of two circulation drilling machine unit heads of design, its structure comprises: power drive mechanism, water tap is suitable for reading corresponding with drilling rod head, wherein actuating unit adopts hydraulic motor, hydraulic motor is connected with the variable gearing in gearbox, and the gear ring on the rotating disk in change-speed gearing and gearbox is in transmission connection, and rotating disk is arranged on drilling rod head top, gearbox, rotating disk, hydraulic motor forms unit head.
When work, hydraulic motor drives dial rotation by gear, the rotation of driven by rotary disc drilling rod head, and drilling rod head drives drilling rod rotation, drill bit operation.Because rotating disk is arranged on boring bar head, in the process of drilling rod rotation, when drilling rod lifting, do not need through rotating disk, but rotating disk is with drilling rod one lifting, can make drilling rod normally rotate, can make again the smooth lifting of drilling rod, the drilling rod head rotating disk that still can pass suitable for reading, makes the water tap of hanging suitable for reading corresponding with drilling rod head, move or stop along the guide rail on pylon, thereby raising drilling efficiency, avoids the wearing and tearing of drilling rod and rotating disk, improve application life; Because rotating disk and hydraulic motor are arranged on boring bar head, power is changed into head by bottom, plays again the counterweight effect to drilling rod head, further improves drilling efficiency.
Brief description of the drawings
Fig. 1 represents the structural representation of the two circulation drilling machine unit heads of the utility model.
Detailed description of the invention
In conjunction with the accompanying drawings and embodiments, further illustrate concrete structure of the present utility model.
The embodiment of the two circulation drilling machine unit heads of the utility model, referring to Fig. 1, its structure comprises: power drive mechanism 1, water tap 2 is suitable for reading corresponding with drilling rod head 4, wherein actuating unit 1 adopts hydraulic motor 1, hydraulic motor 1 is connected with the variable gearing in gearbox 3, again with gearbox in rotating disk on gear ring be in transmission connection, water tap 2 is connected with inverse circulation pump 6 and direct circulation pump 7 by pump line 5, gearbox 3 with hydraulic motor 1 by support along pylon 4 slip liftings, rotating disk is arranged on drilling rod head 4 tops, with fastening being in transmission connection in drilling rod head top.This unit head is also applicable to other rig setting.
