The defect of existing well sinker is: 1, steadiness is poor, dismounting inconvenience; 2, host disk is fixed, and drill bit can not free lift-off ground; 3, the verticality on drilling rod and ground is difficult to revise; 4, only lean on the weight of drilling rod as external force, downforce is not enough; 5, only possess a drilling rod, function singleness, and can only be applicable in good soil layer boring, well-digging, use this well sinker in drift sand formation, the boring of cobble layer, well-digging, the phenomenon of caving in will occur, have very large potential safety hazard.
Summary of the invention
The technical problem that will solve of the present invention overcomes above-mentioned defect, provides a kind of solid and reliable, easy accessibility, and a tractor serves several purposes, effectively can solve landslide, guarantee two bar well sinkers of production safety.
For solving the problem, the technical solution adopted in the present invention is:
A kind of two bar well sinker, comprises frame, the draw-gear be located in frame, the drilling rod that is movably arranged on the unit head in frame and is fixedly mounted on bottom unit head; Described unit head comprises rig head, is fixed on the movable sleeve of rig head both sides, is fixed on the motor in rig crown portion, hitching frame and grout pipe, and is fixed on the safety chuck bottom rig head; It is characterized in that: described safety chuck comprises outer safety chuck and is located at the interior safety chuck in outer safety chuck, described drilling rod comprises outer drilling rod and is located at the interior drilling rod in outer drilling rod, and the external diameter of interior drilling rod is less than the internal diameter of outer drilling rod; Interior drill rod thread is connected on interior safety chuck, and outer drill rod thread is connected on outer safety chuck.
Improvement as technique scheme:
Described frame comprises horizontal base, is vertically fixedly mounted on portal frame on horizontal base and support bar; Unit head is movably arranged on portal frame by movable sleeve; Support bar is provided with two, and its upper end is fixedly connected on the end of portal frame back timber, and lower end is fixedly connected on the end of horizontal base far-end frame.
Described draw-gear comprises hoist engine, provides the motor of power, wire rope, fixed pulley to hoist engine, in establish the suspension hook of movable pulley, retainer ring and mounting ring; Hoist engine and motor are all fixedly mounted on horizontal base; Fixed pulley and retainer ring are all fixed on the middle part of portal frame back timber, and fixed pulley is located at the top of retainer ring; Be fixed on retainer ring after the movable pulley successively through fixed pulley, suspension hook of one end of wire rope, the other end is fixed on arbor after being wound around on the arbor of hoist engine; Mounting ring is fixed on the middle part of hitching frame back timber, and is articulated on suspension hook.
Owing to have employed technique scheme, compared with traditional well sinker, the invention has the advantages that: 1, planer type structure, solid and reliable, easy accessibility; 2, movable unit head, makes the free lift-off ground of rig head energy; 3, the guidance quality of portal frame can revise the verticality on drilling rod and ground effectively; 4, the weight of unit head increases the pressure bored when beating downwards, supplements the deficiency of drilling rod weight; 5, a tractor serves several purposes, alone outer drilling rod can beat large-scale stake holes, the small-bore more than when alone interior drilling rod can make a call to 1, and inside and outside drilling rod to cave in problem with then effectively solving the unstable strata such as cobble, drift sand, guarantees production safety.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
