Abstract
The utility model provides a deslagging head device for a double-pipe directional drilling machine. The deslagging head device for the double-pipe directional drilling machine is characterized in that a guiding rod is welded inside a connecting hole of the center of an end cover, packing is installed inside a nut, a drilling rod penetrates through an inner circle hole of the nut in a coaxial mode, threads at one end of the guiding rod is connected with the nut, the packing is fixed through the shaft end of the guiding rod and the inner wall of the nut, the inner circle of the packing is connected with the outer circle arm of the drilling rod in a coaxial and sealing mode, one end of a tee-joint pipe is welded on the outermost side of the outer circle of the end cover, the other end of the tee-joint pipe is welded inside an inner circle hole of a connecting flange, a deslagging pipe is welded below the tee-joint pipe, the outer circle of a sealing plate is welded on the inner wall of the tee-joint pipe, the outer circle of a driving sleeve is connected with a connecting hole inside the sealing plate, sealing elements are installed inside two sealing grooves of the connecting hole inside the sealing plate, and the sealing elements and the driving sleeve form sealing. The deslagging head device for the double-pipe directional drilling machine has the advantages of effectively discharging water, coal slag and gas inside a sealing cavity and improving working efficiency of drilling. Due to the fact that the packing is sealed through adjustment of the nut, the service life of the packing is improved, and consumption of wearing parts is reduced.
Description
Technical field
The utility model relates to a kind of deslagging head unit, particularly a kind of two-tube directional drilling machine deslagging head unit.
Background technology
Two-tube directional drilling machine carries out driller's work with sleeve pipe and drilling rod cooperation.In drilling process, sleeve pipe and drilling rod annular space can produce a large amount of water, cinder, gas, need to use special tool to discharge.At present existing rig is with not having water, the cinder in energy exclusion sleeve and the drilling rod annular space, the effective tool of gas in the deslagging instrument.
Summary of the invention
The purpose of this utility model is the deficiency that exists in solving the problems of the technologies described above, and a kind of two-tube directional drilling machine deslagging head unit is provided, and is that a kind of deslagging is effective, high efficiency, safe two-tube directional drilling machine deslagging head unit.
The purpose of this utility model is to realize like this, comprise nut, packing, conduit, end cap, tee piece, scum pipe, seal, sealing plate, adpting flange, the active sleeve pipe, drilling rod, it is characterized in that: connecting hole is set in the sealing plate, two place's seal grooves are set on the interconnecting hole, the center of end cap arranges connecting hole, one end of guide rod is provided with screw thread, the other end is welded in the connecting hole at end cap center, packing is installed in the nut, the coaxial interior circular hole that passes nut of drilling rod, the screw thread of guide rod one end is connected with nut, by the axle head of guide rod and the inwall of nut packing is fixed, the interior circle of packing is connected with the cylindrical arm co-axial seal of drilling rod, one end of tee piece is welded on the outermost of end cap cylindrical, the other end is welded in the interior circular hole of adpting flange, scum pipe is welded on the below of tee piece, the cylindrical of sealing plate is welded on the inwall of tee piece, the cylindrical of active sleeve pipe is connected with the connecting hole in the sealing plate, seal is installed in two place's seal grooves of the connecting hole in the sealing plate, and forms sealing with the active sleeve pipe.
The beneficial effects of the utility model are: effectively discharge water, cinder, gas in the annular seal space, make two-tube directional drilling machine reach the safe handling effect, high workload efficient.Regulate packing_seal by nut, thereby improve the application life of packing, reduce the consumption of easy wearing detail.
Description of drawings
Fig. 1 is structure chart of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing this example is described further
As shown in Figure 1, the utility model is welded to form a main body by conduit 3, end cap 4, tee piece 5, scum pipe 6, sealing plate 8 and adpting flange 9, constitutes assembly of the present utility model with nut 1, packing 2, seal 7.Wherein, packing 2 is installed in the nut 1, the drilling rod 11 coaxial interior circular holes that pass nut 1, the screw thread of guide rod 3 one ends is connected with nut 1, by the axle head of guide rod 3 and the inwall of nut 1 packing 2 is fixed, the interior circle of packing 2 is connected with the cylindrical arm co-axial seal of drilling rod 11, make left part of the present utility model realize sealing, when left part of the present utility model has water to ooze out, illustrate that the interior circle of packing 2 this moment and the cylindrical arm of drilling rod 11 wear and tear, by rotating nut 1 with packing 2 stubborn being pressed on the axle head of guide rod 3, the power that produces during by rotation nut 1 can make packing 2 produce deflection between nut 1 and conduit 3 axle heads, and this deflection can continue on for the sealing of sealing drilling rod 11, thereby improve the application life of packing, reduce the consumption of easy wearing detail.Scum pipe 6 is welded on tee piece 5 belows, and the cover plate 4 with left part after sealing plate 8 is welded in the tee piece 5 forms a separate cavities, and the water, cinder and the gas that produce when drilling rod 11 probings flow into this separate cavities, are rejected to outside this device by scum pipe 6.Seal 7 is installed in and is used for initiatively sleeve pipe 10 of sealing in the annular groove of sealing plate 8, thereby the right part that guarantees this device has sealing.Whole each assembly is connected to a fixed by the unit head on connector and the two-tube directional drilling machine by adpting flange 9.During work, water, cinder and the gas that probing produces enters above-mentioned separate cavities by the annular space of 11 on active sleeve pipe 10 and drilling rod, by scum pipe 6 water, cinder and gas is derived again, realizes deslagging in the hole.
