Background technology
Horizontal directional drilling machine is the non-excavation special drilling machine that is widely used in fields such as oil, natural gas, electric power, telecommunications at present, it relies on the amount of deflection of drilling rod to get around obstruction in the certain curvature radius, avoids destroying pipeline through directional drilling under the area ecological environment condition, it is fast to have speed of application, the efficient height, characteristics such as crossing length is long, and the degree of depth is dark.The main composition of horizontal directional drilling machine comprises chassis, unit head, mast, engine device, drilling rod automatic access device, vice, anchor device, hydraulic pressure, part such as automatically controlled.Wherein unit head is the core institution that enforcement is crept into, and its effect is that the slide force of rig and rotary torque are delivered to drilling rod through output shaft, and finishes the big degree of depth by the drilling rod relay and creep into operation, will have liquid to pass through from drilling rod when creeping into.The output shaft of existing unit head is an overall structure, output shaft directly is connected with the driven gear of unit head, not flexible of axis body self, this structure unit head when the loading and unloading drilling rod advances and can produce bigger impact force, this impact force action is easy to cause screw thread to damage at drilling rod tapered tread place so that drilling rod is scrapped, in addition, impact force also can produce the impact injury effect to travelling gear and hydraulic motor.
Summary of the invention
The utility model is used to overcome the defective of prior art and provides a kind of output shaft scalable slip, avoids the drilling rod screw thread is caused the unit head output shaft device of the horizontal directional drilling machine of damage.
The alleged problem of the utility model is that following technical scheme solves:
A kind of unit head output shaft device of horizontal directional drilling machine, it comprises output shaft 1 in constituting, mandrel 4, outer sleeve 14, inner spline housing 3, external splines cover 2 and back back-up ring 10, described output shaft, mandrel, outer sleeve is hollow shaft, described outer sleeve is driven by travelling gear, in described, the external splines cover is separately positioned on the afterbody of outer sleeve axle head and output shaft, both are linked to each other by attachment bolt 16, described mandrel is positioned at outer sleeve and is slidingly connected with outer sleeve, mandrel front end and output shaft are affixed, back-up ring after the rear end is threaded leaves axial stretching space 6 between described output shaft and the outer sleeve.
The unit head output shaft device of above-mentioned horizontal directional drilling machine, described output shaft leading section is provided with the tapered tread 19-1 that is connected with drilling rod 19.
The unit head output shaft device of above-mentioned horizontal directional drilling machine, described mandrel 4 rear end endoporus are provided with conduit 13, are provided with black box 11 between conduit and mandrel, and end of conduit is docked with feed tube 12.
The utility model is an overall structure at existing level directional drilling machine unit head output shaft, the non-retractable problem of axis body self is improved, its output shaft device is by output shaft, outer sleeve and mandrel are formed, overcoat beam warp spline housing is delivered to output shaft with rotary torque, leave a buffer gap between output shaft and the outer sleeve, this structure makes the output shaft segment distance that can axial stretching slides, when avoiding on the dismounting drilling rod shackle screw thread is produced impact force, and rotary torque and axial force are acted on simultaneously, can also guarantee that not having drill-in fluid during at telescopic process at output shaft leaks.Can obviously prolong the application life of drilling rod through after the above-mentioned improvement, and significantly reduce impact force unit head travelling gear and hydraulic motor.
Description of drawings
Fig. 1 is a unit head output shaft structural representation;
Fig. 2 is the A portion zoomed-in view of Fig. 1;
Fig. 3 is the B portion zoomed-in view of Fig. 1.
Number in the figure is as follows: 1. output shaft; 2. external splines cover; 3. inner spline housing; 4. mandrel; 5. preceding back-up ring; 6. axial stretching space; 7. hydraulic motor; 8. driving gear; 9. driven gear; 10. back-up ring after; 11. black box; 12. feed tube; 13. conduit; 14. outer sleeve; 15. gear-box; 16. attachment bolt; 17. fore bearing; 18. rear bearing; 19. drilling rod; 19-1. tapered tread.
The specific embodiment
Referring to Fig. 1, symmetrically arranged hydraulic motor 7 provides power for output shaft 1 on the unit head, and hydraulic motor drives driving gear 8 and rotates, and is delivered on the outer sleeve 14 by driven gear 9 again, drives outer sleeve and rotates.
The output shaft device comprises output shaft 1, mandrel 4, outer sleeve 14, inner spline housing 3, external splines cover 2 and back back-up ring 10, described output shaft, mandrel, outer sleeve are hollow shaft, inside and outside spline housing is separately positioned on the axle tail of outer sleeve axle head and output shaft, and both are linked to each other by attachment bolt 16.Back-up ring 5 before being provided with between inside and outside spline housing.Mandrel 4 is positioned at outer sleeve, is slidingly connected with outer sleeve, the mandrel front end protrudes the overcoat shaft portion and is connected with the output shaft tailing screw flight, and it is locking to be fixed with soldered, leaves axial stretching space 6 between output shaft and the outer sleeve, back-up ring 10 after core back-end is threaded.The rotary torque transitive relation is: outer sleeve drives inside and outside spline housing; The external splines cover drives output shaft; Output shaft drives drilling rod 19, is connected by tapered tread 19-1 between output shaft and drilling rod.
For preventing that output shaft drill-in fluid in telescopic process from leaking, at mandrel 4 rear end endoporus conduit 13 is set, be provided with black box 11 between conduit and mandrel, end of conduit is docked with feed tube 12.The opening of drill-in fluid on feed tube flows to conduit, flows out through conduit, mandrel, output shaft, drilling rod again.
Output shaft returns and drags process, external force to impose on gear-box 15, passes to outer sleeve 14 by fore bearing 17, the transverse plane of outer sleeve afterbody promotes back back-up ring 10, and back back-up ring links to each other with mandrel 4 by screw thread, and power is passed to mandrel, mandrel links to each other with output shaft 1 by screw thread, and active force is by the screw thread transmission.Progradation is given outer sleeve 14 by rear bearing 18 transmission power, directly promotes output shaft 1 by outer sleeve front end face again.Above-mentioned design can make that need not whole unit head when unloading screw thread on the loading and unloading drilling rod moves, and just output shaft flexible getting final product in axial stretching space 6 reaches the purpose of minimizing to the impact force of drilling rod screw thread.
