Abstract
The utility model discloses a novel wired guiding connection wire compressing device of directional drilling machine. The mechanism comprises a core shaft, rubber ball, ball compressing screw, a hollow plug and the like, wherein the rubber ball is arranged in the core shaft, the rear end is blocked by the hollow plug, and the ball compressing screw is arranged in the hollow plug and is screwed to compress the rubber ball. The utility model has the advantages that the rubber ball can be conveniently compressed via the adjustment of the ball compressing screw, pressure water of a core shaft hole can be sealed and electric wires can be wrapped up via the deformation of the rubber ball, and simultaneously, the rubber ball has good elasticity and can prevent the electric wire from being compressed to deform.
Description
Technical field
The utility model relates to a kind of wired guiding wiring hold down gag, the particularly a kind of wired guiding wiring of novel directional drilling machine hold down gag that uses on horizontal directional drilling machine.
Background technology
The large-tonnage horizontal directional drill is subjected to directed the boring of condition restriction large-tonnage such as distance generally all to adopt wired guiding.Wired guiding includes line sensor, cable power, special-purpose plug-pull tool, and electric wire, drums etc. are formed a measuring system jointly, can measure the distance of creeping into forward by particular instrument.
The electric wire that wherein is used for measuring distance needs to pass in unit head quill shaft and drilling rod successively, and the unit head quill shaft also will be carried the press water of certain flow simultaneously, so need the position that electric wire passes the quill shaft afterbody be sealed, to prevent the excessive of press water.Directed the boring of tradition large-tonnage generally adopted the position of passing electric wire at the quill shaft afterbody, with a plastic flat pad sealing.Electric wire passes the hole in the middle of the plain cushion, has a clamp nut to compress plain cushion in the plain cushion back.Though can realize compressing the purpose that water is sealed in electric wire border and then realization in this way, plain cushion is thin to be difficult for fitting with electric wire comprehensively, might cause the plain cushion distortion excessive and then with electric wire crimp again as undue fastening nut.Therefore need find a kind ofly both can seal up press water, guarantee that again the device that electric wire is not crushed out of shape replaces above-mentioned compressing structure.
Summary of the invention
The purpose of this utility model provides a kind of wiring hold down gag that is arranged in unit head quill shaft rear portion, both can seal up press water, can electric wire is not crushed out of shape by an amount of adjusting again.
Structure of the present utility model is by mandrel, ball, pressure ball screw, compositions such as hollow plug.Ball is installed in the mandrel, and the rear end is blocked with the hollow plug, and the pressure ball screw is installed in the hollow plug, tightens and pushes down ball.
Have in the middle of the described ball with the through hole that matches by electric wire.
The internal thread identical with the pressure ball screw arranged in the middle of the described hollow plug.
Described pressure ball screw is an outer end band bell, the centre have with the through hole that matches by electric wire.
The utility model has the advantages that and to compress ball easily by regulating the pressure ball screw that can seal the press water in mandrel hole and wrap electric wire by the ball distortion, the favorable elasticity that the while ball has can prevent that again electric wire is crushed out of shape.
Description of drawings
Fig. 1 is a side sectional structure chart of the present utility model.
Among the figure, 1 mandrel; 2 ball; 3 pressure ball screws; 4 hollow plugs; 5 electric wires.
The specific embodiment
Embodiment 1: mandrel 1 is fixed on the unit head rear portion, and electric wire 5 diameters are a bit larger tham in mandrel 1 front end perforate, and there is a cylindrical hole at the rear portion, and diameter is identical with ball 2, and there is an internal thread cylindrical hole back, is used to tighten hollow plug 4.
Line is placed on 1 li of mandrel with ball 2 during installation, and the holes of crossing electric wires 5 in the middle of the ball 2 communicate with the hole of front mandrel, and then tighten hollow plug 4, the pressure ball screw 3 of screwing on of the screwed hole back warps in the middle of hollow plug 4.
In when construction, unclamp pressure ball screw 3 earlier, electric wire 5 is passed hole in the middle of pressure ball screw 3 and the ball 2 successively, pass the hole of mandrel 1 again, just electric wire 5 can have been guided to the front.After electric wire 5 is moved the position to, pressure ball screw 3 is screwed, be screwed onto when contacting with ball 2, it is just passable to twist 1/2 circle again.Pressure ball screw 3 one end band bells can prevent that electric wire is scratched when penetrating interstitial hole.
Press water during construction is forcing its compressive deformation when ball 2 is oppositely oppressed in the mandrel hole, thereby wraps electric wire 5 tightly, and also combine closely with mandrel 1 inner ring in ball 2 outer rings simultaneously, thereby reaches the purpose that seals the power and water line and do not destroy electric wire.
