Description
Technical field
The present invention relates to the laying project field of a kind of non-excavation underground pipeline, particularly a kind of horizontal directional drill machine creeps into and uses warning drilling rod.
Background technology
The application of Horizontal Directional Drilling in trenchless pipelaying engineering is very extensive, and piping work is generally divided into three phases, namely pilot hole creep into, pull back reaming and pipeline laying. Pilot hole refers to that first drill bit that utilize band inclined-plane, that diameter is less forms the guiding hole of minor diameter according to predetermined planned course, for follow-up reaming and pipe laying provide guidance function. In construction process, drilling rod is as the instrument of underground workings, work situation is complicated and changeable, difference is very big, practical experience tell the greatest danger of our drilling rod fatigue be exactly excessively become to, so-called excessively become to refer to the change of the specified minimum bending radius exceeding drilling rod to, excessively become to being the reason causing drill pipe wear, drilling rod can be caused to fracture. Practice of construction is crept into due to orientation become to time drilling rod can produce the bending of certain amount of deflection, drilling rod becomes to mainly containing following three kinds: the bending change adjusting to vertical direction when horizontal section changes by the section of burying to, adjust to unearthed section by horizontal section time vertical direction bending change to need to walk around during guiding underground obstacle horizontal or vertical direction bending change to. But because the polytropy in pilot guide bit direction in guiding process is difficult to true accurately measure in practice of construction process, thus how to ensure drilling rod become to time do not exceed the specified minimum bending radius of drilling rod, just become technical issues that need to address.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, it is proposed to one avoids drilling rod generation overbending to be out of shape, and the horizontal directional drill machine that can extend drilling rod work-ing life creeps into uses warning drilling rod.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of horizontal directional drill machine creeps into uses warning drilling rod, comprise drill rod body, it is fixed with female joint in the rear end of drill rod body, the inside of female joint is provided with washing fluid admission chamber, it is fixed with male joint in the front end of drill rod body, the inside of male joint is provided with washing fluid and goes out sap cavity, it is characterized in: be provided with the hollow straight body of rod axially parallel with drill rod body in the inside of drill rod body, the straight body of rod rear portion of hollow is provided with the fixed middle boss coordinated in determining with drill rod body inwall, the inwall of drill rod body is provided with and the positioning spigot that surely middle boss coordinates, the inner chamber of the straight body of rod of described hollow is set to go out the passage of irrigation fluid I that sap cavity communicates with washing fluid admission chamber and washing fluid, between the outer wall of the straight body of rod of hollow and the inwall of drill rod body, room, chamber is set to passage of irrigation fluid II, the circumference of boss is provided with the split channel of some connection passage of irrigation fluid II with washing fluid admission chamber in surely, it is provided with washing fluid trip switch in the inside of the front drill rod body of the straight body of rod of hollow, described washing fluid trip switch comprises and the valve seat that drill rod body inwall is fixedly connected, valve seat is provided with the washing fluid through-flow channel going out sap cavity with washing fluid and communicating, it is provided with along the axial arranged guide path of drill rod body at the rear portion of valve seat, the spool that slide anteroposterior opens and closes washing fluid through-flow channel it is provided with in guide path, compression spring it is provided with between spool and valve seat, at the opening that the rear end of spool has with washing fluid through-flow channel communicates, the taper guiding cap that beloid lever front end face straight with hollow coordinates it is provided with at opening place, the straight lever front end face of described hollow stretch in taper guiding cap and passage of irrigation fluid I with opening just to setting, the through hole of some connection passage of irrigation fluid I with passage of irrigation fluid II it is provided with in the front portion of the straight body of rod of hollow, at the positioning step that the inside of drill rod body is provided with taper guiding cap coordinates.
The technical problem to be solved in the present invention can also be come to realize further by the following technical programs, and the straight body of rod of described hollow comprises front thin bar body and rear thick bar body, and the rear portion of front thin bar body connects with the front threads of rear thick bar body.
The technical problem to be solved in the present invention can also be come to realize further by the following technical programs, is equipped with handling groove when spanner loads and unloads on the outer wall of front thin bar body and rear thick bar body.
The technical problem to be solved in the present invention can also be come to realize further by the following technical programs, is provided with two groups before and after described through hole side by side, and often group is all uniformly distributed along the circumference of front thin bar body.
Compared with prior art, present configuration is simple, reliable operation, easily realize, the straight body of rod of hollow utilizing the inside being arranged on drill rod body axially parallel with drill rod body, if in pilot hole drilling process occur drilling rod excessively become to, spool will be forced to move forward along valve seat guide path under the resistance of compression spring, spool is made automatically to close washing fluid through-flow channel, thus earth's surface slush pump gage indicates sharply rising to send alarm, like this, decrease the breaking of rod accident that drilling rod occurs in underground construction because of overbending, protect drilling rod to avoid overbending distortion, extend the work-ing life of drilling rod, reduce construction cost.
