Specific embodiment
Particular content of the present utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, gravity type helicoid hydraulic motor, including：Pressure pipe 1, slides in the pressure pipe 1 and is provided with sealing ring
2, pressure chamber 3 is provided with the pressure pipe 1 of the upper end of the sealing ring 2, set in the pressure pipe 1 of the lower end of the sealing ring 2
Lower pressure chamber 4 is equipped with, the upper end of the pressure pipe 1 is provided with swivel nut 5, be provided with the swivel nut 5 and cooperated with it
Screw rod 6, the upper end of the screw rod 6 is connected with drilling rod 7, the lower end of the screw rod 6 stretch into pressure pipe 1 with the phase of sealing ring 2
Connection, is evenly arranged with some upper inlet openings 8 being interconnected with upper pressure chamber 3, in the pressure pipe 1 on the swivel nut 5
Lower end be provided with drill bit 9, be provided with the drill bit 9 with lower pressure chamber 4 be interconnected lower inlet opening 10.
When above-mentioned gravity type helicoid hydraulic motor is used, gravity type helicoid hydraulic motor is put into oil pipe 11, the lead-screw of drilling rod 7
6 move along a straight line downwards in oil pipe, and screw rod 6 drives pressure pipe 1, swivel nut 5 and drill bit 9 to move along a straight line downwardly together, when drill bit 9 with
When liquid in oil pipe is contacted, lower inlet opening 10 of the liquid from drill bit 9 enter into sealing ring 2 is caused in lower pressure chamber 4 to
On thrust, sealing ring 2 has upward thrust to screw rod 6, so as to promote swivel nut 5 to be rotated on screw rod 6, swivel nut 5 drives
Pressure pipe 1 rotates, and pressure pipe 1 drives drill bit 9 to rotate；When the upper lifting power formula helicoid hydraulic motor from oil pipe 11, drilling rod 7 pulls spiral shell
Bar 6 moves along a straight line upwards in oil pipe, and screw rod 6 drives pressure pipe 1, swivel nut 5 and drill bit 9 to move along a straight line upwards together, oil pipe 11
Upper inlet opening 8 of the interior water from swivel nut 5 enters into upper pressure chamber 3 and downward thrust, sealing ring 2 pairs is caused to sealing ring 2
Screw rod 6 has downward thrust, so as to promote swivel nut 5 to be reversely rotated on screw rod 6, swivel nut 5 drives pressure pipe 1 reversely to revolve
Turn, pressure pipe 1 drives drill bit 9 to reversely rotate；
Above-mentioned gravity type helicoid hydraulic motor, structure is novel, easy to assembly, is coordinated using swivel nut and screw rod and replaces original rotor
Coordinate with stator, prevent the stuck phenomenon in stator of rotor, applied widely, long service life.
