Description
Technical field
The utility model belongs to petroleum drilling and mining helicoid hydraulic motor technical field, and in particular to a kind of helicoid hydraulic motor anti-boom anticreep
Device.
Background technology
Helicoid hydraulic motor is most widely used a kind of mud motor in current petroleum exploration and development, is mainly used for orienting
Well, horizontal well deflecting and turn round orientation construction, a part is also used for the special wells such as straight well left-hand thread or side-drilling windowing drilling well/repair
In well operations.Helicoid hydraulic motor includes mainly by-pass valve assembly, motor assembly, universal axle assembly and driving-shaft assembly, horse therein
Include stator, rotor and anti-boom up to assembly.During wellbore construction, helicoid hydraulic motor shell is in the feelings for being hampered or discharging suddenly
Dropout is be easy to cause under condition.Shell can pull inner rotator position to fall down after falling off, anti-boom can effectively prevent rotor after
It is continuous to fall, play anti-lost effect.But existing rotor is to be threadedly coupled with anti-boom, in use due to hydraulic blow
Releasing or falling off for anti-boom threaded connection is easily caused with reasons such as rotor rotations, causes final anti-boom to fail, threaded shank
Divide and fall well, causes serious consequence.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of knot in view of the deficiency of the prior art
Structure is arranged helicoid hydraulic motor anti-boom anti-drop device reasonable, safe and reliable, convenient for disassembly and assembly.
Technical solution used by the utility model is：Including rotor and anti-boom, rotor upper end offers threaded hole, prevents
Fall bar lower end and be provided with external screw thread, rotor and anti-boom and be connected with external screw thread by threaded hole, it is characterised in that in rotor
Threaded hole port offers hole shoulder, and card slot is opened up above the shoulder of hole and is installed on clamp spring, correspondence is set above the external screw thread of the anti-boom
Sleeveless jacket is set, sleeveless jacket is with hole shoulder phase configuration and under clamp spring after anti-boom is connect with rotor threads.
By said program, threaded hole and the rotor coaxial line of the rotor, threaded hole lower end offers escape, threaded hole
Port opens up the larger hole shoulder in aperture.
By said program, the anti-boom is provided at both ends with external screw thread, and the externally threaded top in lower end is provided with outer diameter
Larger sleeveless jacket.
By said program, the sleeveless jacket and hole shoulder phase configuration, and embedded clamp spring and hole shoulder at annular groove in, between axial direction
Gap is maintained at 0.1~0.5.
Having the beneficial effect that acquired by the utility model：
1. the utility model is connected to form first of anti-lost company of anti-boom and rotor by internal thread, external screw thread
It connects, the axial movement of anti-boom is further limited by providing holes shoulder, sleeveless jacket and clamp spring, prevents the slippage of anti-boom, formed double
Reorientation, locking effect is good, safe and reliable；
2. simple in structure, easy to disassemble, the utility model mainly passes through outer, screw-internal thread fit and sleeveless jacket clip spring structure, dress
Distribution structure is simple, follow-up convenient for disassembly and assembly.

Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown in Figs 1-4, a kind of helicoid hydraulic motor anti-boom anti-drop device is present embodiments provided, including rotor 1 and anti-lost
Bar 2,1 upper end of rotor offer threaded hole, and 2 lower end of anti-boom is provided with external screw thread 21, and rotor 1 and anti-boom 2 pass through threaded hole
It is connected with external screw thread 21, offers hole shoulder 12 in the threaded hole port of rotor 1, shoulder 12 top in hole opens up card slot 13 for installing
The top of external screw thread 21 of clamp spring 3, anti-boom 2 is correspondingly arranged sleeveless jacket 22, after anti-boom 2 is threadedly coupled with rotor 1 sleeveless jacket 22 and
Shoulder 12 phase configuration in hole is simultaneously located under clamp spring 3.
In the present embodiment, threaded hole and 1 coaxial line of rotor of rotor 1, threaded hole lower end offers escape 14, threaded hole
Port opens up the larger hole shoulder 12 in aperture.
Anti-boom 2 is provided at both ends with external screw thread 21, and in lower end, the top of external screw thread 21 is provided with the larger sleeveless jacket 22 of outer diameter.
Sleeveless jacket 22 and 12 phase configuration of hole shoulder, and embedded clamp spring 3, with the annular groove of the formation of hole shoulder 12, axial gap is maintained at
0.1~0.5.It is connected to form first of anti-lost connection of anti-boom and rotor in internal thread, external screw thread, passes through providing holes shoulder
12, sleeveless jacket 22 and clamp spring 3 further limit the axial movement of anti-boom 2, prevent the slippage of anti-boom 2.
It should be understood that above-described embodiment is merely to illustrate the utility model rather than limitation the scope of the utility model.This
