Two semicircle shape hoops embrace the outer tube surface of interpolation pipe, and the first radial flange of the first semicircle shape hoop respectively with institute
The second radial flange for stating the second semicircle shape hoop is oppositely arranged, and is each passed through first semicircle using anchor ear fixing bolt
It is tightened after second radial flange of the first radial flange of shape hoop and the second semicircle shape hoop, thus by described
One semicircle shape hoop and the second semicircle shape hoop are fixed on the outer tube surface of interpolation pipe.
In a preferred embodiment of the utility model, the pulley mounting base is arranged by relative spacing in the anchor ear
Outer peripheral surface on two pieces of trapezoidal fixed tabs constitute, the pulley by a pulley shaft be rotatably installed in described two pieces it is trapezoidal
Between fixed tab and the outermost end of the outer peripheral surface of the pulley is exposed between two pieces of trapezoidal fixed tabs.
In a preferred embodiment of the utility model, the anchor ear is steel anchor ear.
In a preferred embodiment of the utility model, the trapezoidal fixed tab is made of steel, and passes through welding
Mode is fixed on the outer peripheral surface of the anchor ear.
Due to using technical solution as above, the utility model has the beneficial effects that: outer sheath tube Directional Drilling is completed
Afterwards, one group of slide assemblies is set at a certain distance on the outer tube surface for the interpolation pipe for needing interpolation, so that interpolation pipe is outside
Sliding friction occurs with the inner tube surface of outer sheath tube after protecting pipe, the resistance of this sliding friction is smaller, on the one hand substantially reduces
The dilatory force that interpolation pipe is dragged in, while also avoiding occurring between the inner tube surface of outer sheath tube and the outer tube surface of interpolation pipe
Direct static friction causes the outer tube surface of interpolation pipe to damage so as to avoid the excessive friction between interpolation pipe and outer sheath tube,
Improve the service life of interpolation pipe.The slide assemblies in-site installation of the utility model is convenient, and speed of application is fast, and structure is simply real
With, it is cheap, it is suitble to large-scale use.

Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Referring to attached drawing, what is provided in figure is a kind of slide assemblies applied in Directional Drilling interpolation pipe technique, including anchor ear
100 and four pulleys 200.
Fixed embrace of anchor ear 100 is located on the outer tube surface of interpolation pipe 10, and anchor ear 100 is steel anchor ear.Specifically, anchor ear 100
It is put together by the first semicircle shape hoop 110 and the second semicircle shape hoop 120, the two of the first semicircle shape hoop 110
End is respectively formed with a radial flange 111, is respectively formed with a radial flange 121 at the both ends of the second semicircle shape hoop 120.
When installation, the first semicircle shape hoop 110 and the second semicircle shape hoop 120 embrace the outer tube surface of interpolation pipe 10, and the first half
Radial flange 121 of the radial flange 111 of round shape hoop 110 respectively with the second semicircle shape hoop 120 is oppositely arranged, and is used
Anchor ear fixing bolt 20 is each passed through the radial flange 111 and the second semicircle shape hoop 120 of the first semicircle shape hoop 110
