Abstract
The invention discloses a gravity type screw drill which is long in service life. The gravity type screw drill comprises a pressure pipe. A sealing ring is arranged in the pressure pipe in a sliding mode, an upper pressure cavity is formed in the part, at the upper end of the sealing ring, in the pressure pipe, and a lower pressure cavity is formed in the part, at the lower end of the sealing ring, in the pressure pipe. A threaded sleeve is arranged at the upper end of the pressure pipe, a screw matched with the threaded sleeve is arranged in the threaded sleeve, the upper end of the screw is connected with a drill stem, the lower end of the screw stretches into the pressure pipe and is connected with the sealing ring, a plurality of upper water inlet holes communicated with the upper pressure cavity are evenly formed in the threaded sleeve, a drill bit is arranged at the lower end of the pressure pipe, and a lower water inlet hole communicated with the lower pressure cavity is formed in the drill bit. The gravity type screw drill has the advantages that the gravity type screw drill is novel in structure, convenient to assemble, wide in application range and long in service life, and the phenomenon that a rotor is stuck in a stator is eradicated as original rotor and stator matching is replaced with threaded sleeve and screw matching.
Description
Technical field
The present invention relates to a kind of petroleum machinery, particularly relate to a kind of gravity type helicoid hydraulic motor.
Background technology
The rotor that existing threaded rod power drill set relies on fluid pressure to drag helicoid hydraulic motor rotates, and pressure can be become mechanical energy.The subject matter that this drilling tool exists is that service life is short, and rotor is the most stuck in stator, requires higher to well temperature and power fluid, is difficult to adapt to present drilling well task.
Summary of the invention
The technical problem to be solved is: provide the gravity type helicoid hydraulic motor of length in a kind of service life.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: gravity type helicoid hydraulic motor, including: manometer tube, slide in described manometer tube and be provided with sealing ring, it is provided with upward pressure chamber in the manometer tube of described sealing ring upper end, it is provided with downforce chamber in the manometer tube of described sealing ring lower end, the upper end of described manometer tube is provided with swivel nut, the screw rod cooperated with it it is provided with in described swivel nut, the upper end of described screw rod is connected with drilling rod, the lower end of described screw rod is connected with sealing ring in stretching into manometer tube, described swivel nut is evenly arranged with some upper inlet openings being interconnected with upward pressure chamber, the lower end of described manometer tube is provided with drill bit, described drill bit is provided with the lower inlet opening being interconnected with pressure chamber.
The invention have the advantage that above-mentioned gravity type helicoid hydraulic motor, novel structure, easy to assembly, employing swivel nut and screw rod coordinate and replace original rotor and stator cooperation, stop the stuck phenomenon in stator of rotor, and applied widely, service life is long.

Fig. 1 is the structural representation of gravity type helicoid hydraulic motor of the present invention.
In figure: 1, manometer tube, 2, sealing ring, 3, upward pressure chamber, 4, downforce chamber, 5, swivel nut, 6, screw rod, 7, drilling rod, 8, upper inlet opening, 9, drill bit, 10, lower inlet opening, 11, oil pipe.
Detailed description of the invention
The particular content of the present invention is described in detail below in conjunction with the accompanying drawings with specific embodiment.
As shown in Figure 1, gravity type helicoid hydraulic motor, including: manometer tube 1, slide in described manometer tube 1 and be provided with sealing ring 2, it is provided with upward pressure chamber 3 in the manometer tube 1 of described sealing ring 2 upper end, it is provided with downforce chamber 4 in the manometer tube 1 of described sealing ring 2 lower end, the upper end of described manometer tube 1 is provided with swivel nut 5, the screw rod 6 cooperated with it it is provided with in described swivel nut 5, the upper end of described screw rod 6 is connected with drilling rod 7, the lower end of described screw rod 6 is connected with sealing ring 2 in stretching into manometer tube 1, described swivel nut 5 is evenly arranged with some upper inlet openings 8 being interconnected with upward pressure chamber 3, the lower end of described manometer tube 1 is provided with drill bit 9, described drill bit 9 is provided with the lower inlet opening 10 being interconnected with pressure chamber 4.
When above-mentioned gravity type helicoid hydraulic motor uses, gravity type helicoid hydraulic motor is put in oil pipe 11, drilling rod 7 lead-screw 6 moves along a straight line downwards in oil pipe, screw rod 6 drives manometer tube 1, swivel nut 5 and drill bit 9 to move along a straight line downwardly together, when drill bit 9 contacts with the liquid in oil pipe, sealing ring 2 is caused thrust upwards in entering into downforce chamber 4 by the liquid lower inlet opening 10 from drill bit 9, sealing ring 2 has thrust upwards to screw rod 6, thus promote swivel nut 5 to rotate on screw rod 6, swivel nut 5 drives manometer tube 1 to rotate, and manometer tube 1 drives drill bit 9 to rotate；When upper lifting power formula helicoid hydraulic motor in oil pipe 11, drilling rod 7 pulls screw rod 6 upwards to move along a straight line in oil pipe, screw rod 6 drives manometer tube 1, swivel nut 5 upwards to move along a straight line together with drill bit 9, sealing ring 2 is caused downward thrust in entering into upward pressure chamber 3 by the upper inlet opening 8 from swivel nut 5 of the water in oil pipe 11, sealing ring 2 has downward thrust to screw rod 6, thus promoting swivel nut 5 to reversely rotate on screw rod 6, swivel nut 5 drives manometer tube 1 to reversely rotate, and manometer tube 1 drives drill bit 9 to reversely rotate；
Above-mentioned gravity type helicoid hydraulic motor, novel structure, easy to assembly, use swivel nut and screw rod to coordinate and replace original rotor and stator to coordinate, stop the stuck phenomenon in stator of rotor, applied widely, service life is long.
