Abstract
The utility model relates to a flexible drilling hose lifting/lowering apparatus for a deep perforating machine in an oil well. The utility model is characterized in that a transmission nut with end saw teeth at the lower end is spirally arranged on a spiral tube, a fixed toothed ring is fixed in a machine body hole which is arranged at the upper end of a guide sleeve, and a spring piece is arranged between the upper end of the transmission nut and the top surface of the hole. Accordingly, both perforating holes can be kept nondeflecting, and the lifting efficiency can be improved; simultaneously, the utility model has the advantages of safe utilization and long service life.
Description
The utility model relates to the soft drilling pipe lifting gear that machine is penetrated in a kind of deep penetration.
At present, the soft drilling pipe of existing soft drilling pipe lifting gear is to descend by the screw mechanism rotation to entering the rock stratum, because the guide effect of rotation, can control the correct trend of preforation tunnel, and eyelet is penetrated partially, and soft drilling pipe upwards promotes when reclaiming, pass through screw mechanism too, but hoisting velocity is slow, also easily causes the back-off that is threaded and accident such as get loose.
In view of this, the purpose of this utility model provides the soft drilling pipe lifting gear that machine is penetrated in a kind of deep penetration, and soft drilling pipe descends with the spirally-guided rotation and enters the rock stratum, and reclaims to rotate freely to promote.
The purpose of this utility model is achieved in that a kind of deep penetration penetrates the soft drilling pipe lifting gear of machine, comprise big piston, helix tube, joint, soft drilling pipe, fairlead and body, it is characterized in that: on helix tube, revolve the transmission nut of establishing its lower end band edge sawtooth, set firmly a stationary saw ring gear in the hole of the body on fairlead.
Described end sawtooth and transmission nut are originally as releasable connection.
Between the hole top end face of described transmission nut upper end and body spring leaf is set.
Owing to adopt such scheme: can keep preforation tunnel not depart from, can improve the efficient that soft drilling pipe promotes again, simultaneously safe and reliable, also increase the service life.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model exemplary embodiments structural representation;
Fig. 2 is the A enlarged diagram of the utility model exemplary embodiments Fig. 1;
Among the figure: 1. big piston 2. helix tubes 3. transmission nuts 31. end sawtooth 4. stationary saw ring gears 5. joints 6. soft drilling pipe 7. spring leafs 8. fairleads 9. bodies
Present embodiment mainly comprises big piston 1, helix tube 2, transmission nut 3, stationary saw ring gear 4, joint 5, soft drilling pipe 6, spring leaf 7, fairlead 8 and body 9, as shown in Figure 1, 2, and wherein:
Big piston 1 connects (pivot joint) helix tube 2 upper ends, and helix tube 2 lower end jointings 5 upper ends, and joint 5 lower ends connect soft drilling pipe 6 upper ends, soft drilling pipe 6 lower ends connect the nozzle (not shown), helix tube 2, joint 5 and soft drilling pipe 6 are vacant in fairlead 8, and fairlead 8 upper ends are connected in the hole of body, all belong to prior art.
Transmission nut 3 is nuts that the lower end has end sawtooth 31, this transmission nut 3 screws with helix tube 2 and is vacant in the hole of body 9, transmission nut 3 is wear-resisting bronze material, and its end sawtooth 31 is a steel matter, and end sawtooth 31 can be to fixedly connected or releasable connection with transmission nut 3.
Stationary saw ring gear 4 is that the upper surface has sawtooth or the ring that combines with end sawtooth 31, interior and the fair ground helix tube 2 of putting of body 9 holes that this stationary saw ring gear 4 is fixedly connected on fairlead 8 upper ends passes, and this stationary saw ring gear 4 combines with the end sawtooth 31 of transmission nut 3 transmission nut is maintained static.
Spring leaf 7 is arranged between the hole top end face of transmission nut 3 upper ends and body 9, how the end sawtooth 31 of transmission nut 3 is held with stationary saw ring gear 4 contacts, also a thrust rolling bearing can be set between this spring leaf 7 and transmission nut 3 upper ends, reduce coefficient of friction (not shown) in relative rotation.
The operating principle of present embodiment:
When big piston 1 promotes helix tube 2 downwards, because helix tube 2 downward thrust and spring leaf 7 pressure, it is moving that transmission nut 3 and stationary saw ring gear 4 one are maintained static, and makes helix tube 2 for the helical movement downwards, rotates into the rock stratum through the nozzle of the soft drilling pipe 6 of joint 5 drives;
When big piston 1 upwards spurs helix tube 2, spring leaf 7 pressurizeds, the end sawtooth 31 of transmission nut 3 is thrown off with stationary saw ring gear 4, this moment, transmission nut 3 can rotate freely, but helix tube 2 then straight line move up, drive soft drilling pipe 6 through joint 5 and upwards extract out.
Claims (3)
