Summary of the invention
The purpose of this utility model is to provide a kind of trombone slide fast, reduces tubing loss, reduces and produce and construction cost reusable horizontal directional drill trombone slide folder.
The technological scheme that the utility model adopts is for achieving the above object: a kind of horizontal directional drill trombone slide folder, this horizontal directional drill trombone slide folder comprises outer sleeve, thread and at least two arcuation wedge-shaped blockss, outer sleeve middle part is provided with the shoulder hole that runs through its front/rear end, this shoulder hole comprises and is positioned at the macropore of rear end and is positioned at front end and the little aperture of the larger bore dia of diameter, thread comprises drag link body and is connected to drag link body rear end and is round table-like clamping cylinder, drag link body outer surface is provided with screw thread, the drag link body of thread is passed macropore and is protruded aperture front end by outer sleeve rear end, round table-like clamping column body is positioned at the macropore of outer sleeve, drag link body stretches out the part of outer sleeve front end and is furnished with nut, arcuation wedge-shaped blocks is arranged between the macropore inwall and the external side of round table-like clamping column of outer sleeve, described round table-like clamping cylinder is reduced gradually by rear end to its diameter of front end, and the diameter of round table-like clamping cylinder front end is greater than the diameter of outer sleeve aperture, described arcuation wedge-shaped blocks is increased gradually by rear end to front its thickness.
Further technological scheme of the present utility model is: the drag link body diameter of described thread and the equal diameters of outer sleeve aperture.
The macropore of described outer sleeve and aperture connecting end are provided with vertical transition platform, and the front end of described outer sleeve is provided with conical surface.
The drag link body front end of described thread is provided with through hole.
Described arcuation wedge-shaped blocks is provided with six altogether.
Described arcuation wedge-shaped blocks outer side surface is provided with rough thread form.
Owing to adopting said structure, the horizontal directional drill trombone slide fixture of the utility model has following beneficial effect:
1, the horizontal directional drill trombone slide of the utility model before being clipped in trombone slide unclamps nut, tubing to be laid is clipped in the gap between outer sleeve macropore inwall and arcuation wedge-shaped blocks outer side surface, internal thread broaching pull bar forward afterwards, clamp after tubing tightening nut again, tubing front end is clamped between outer sleeve macropore inwall and arcuation wedge-shaped blocks, in trombone slide process, need only and can pull tubing with the through hole of steel wire penetrating thread front end, after having constructed, unclamp again nut, make tubing depart from outer sleeve and arcuation wedge-shaped blocks, without excision tubing front end, also bushing needle need not be set, can realize trombone slide fast, reduce tubing loss, improve stock utilization, reduce production costs also reusable,
2, adopt after the horizontal directional drill trombone slide folder of the utility model, trombone slide folder can have automatic clamping function to tubing, can improve efficiency of construction, reduces construction cost;
3, adopt the outer sleeve front end of the horizontal directional drill trombone slide folder of the utility model to adopt conical surface structure, can reduce trombone slide resistance, reduce horizontal directional drill engine oil consumption, reduce the requirement of equipment pull-back force;
4, the horizontal directional drill trombone slide of the utility model folder only comprises the members such as outer sleeve, thread, arcuation wedge-shaped blocks, nut, and overall structure is simple, cost of production is low, be beneficial to and apply.
Below in conjunction with the drawings and specific embodiments, the utility model horizontal directional drill trombone slide folder is described further.
