Description
Technical field
The utility model relates to a kind of drilling equipment, specifically a kind of plug-in type threaded connection drill stem.
Background technology
At present, conventional interconnection system drilling rod includes screw connected drilling rod and plug-in type jointed rod.
Plug-in type jointed rod is that the front end at drilling rod is provided with the seal nipple of sealing ring and the outer square joint being connected with seal nipple, in the rear end of drilling rod, be provided with link tail, in link tail inside, be provided with internal square hole, at described link tail and outer square joint, be respectively arranged with pin hole.But this plug-in type jointed rod has certain defect: the one, and this drilling rod torque resistant power is little; The 2nd, after drilling rod connects, linearity is poor; The 3rd, the attended operation process of drilling rod is comparatively loaded down with trivial details, when the square knuckle of a drilling rod is inserted the internal square hole of another root drilling rod, after must aiming at the axis direction of internal square hole, could insert, and need in two pinholes, pound into a pin, the sub difficulty of pulling pin while simultaneously having increased dismounting; The 4th, due to when connecting, sealing ring external diameter extruding drilling rod inner diameter wall, so easily damage sealing ring and produce drainage.Threaded connection drill stem is that the front end at drilling rod is provided with externally threaded connection end, in the rear end of drilling rod, be provided with tapped link tail, but this threaded connection drill stem is easily stuck when boring forward, easily gets loose, thereby cause drilling rod to be lost during reversion.
Utility model content
The purpose of this utility model is just to provide a kind of plug-in type threaded connection drill stem, to solve the bad problem of result of use of existing interconnection system drilling rod.
The utility model is achieved in that a kind of plug-in type threaded connection drill stem, includes:
The drilling rod of hollow;
Be arranged on the link tail of described drilling rod rear end;
Be arranged on the sealed end tail being connected with described link tail in described drilling rod;
Be arranged on the sealing termination with sealing shroud of described drilling rod front end;
Be arranged on the outer polygon joint that is connected with described sealing termination on described drilling rod; And
Be arranged on described drilling rod and described outer polygon joint is connected and diameter is identical with described link tail connection end;
On the external diameter of described link tail, be provided with external screw thread, in the inside of described connection tail end, be provided with the inner polygon hole of matching with described outer polygon joint;
On described connection end, be provided with described link tailspin to consistent external screw thread, at the middle part of described connection end, be provided with spring detent; On described connection end, be threaded connection adapter sleeve;
Described spring detent includes spring and is fixed on the bayonet lock of described spring one end, the other end of described spring is fixedly connected on the inside of described connection end, and described bayonet lock is all or part of exposed inside that is arranged on connection end after described connection end outside, described spring-compressed when spring original state.
Described outer polygon joint is outer quadrangle joint, outer hexagon joint or outer octagon joint, and corresponding described inner polygon hole is interior quadrilateral hole, interior hexagonal hole or interior octagon hole.
Between described sealed end tail and described inner diameter wall, be provided with space.
The utility model in use, by the sealing termination of drilling rod front end and outer polygon joint being inserted into the link tail of drilling rod rear end, so that the sealing termination of drilling rod front end is tightly connected mutually with drilling rod back-end sealing end tail, owing to having space between sealed end tail and inner diameter wall, so avoided making to seal because of wearing and tearing the generation of the damage drainage that the sealing ring of termination produces.Now, outer polygon joint is inserted in inner polygon hole, connection end contacts with link tail, then, be screwed in the adapter sleeve on connection end, make its part spiral be connected to connection end, part spiral is connected to link tail, and make the bayonet lock in spring detent stretch out connection end, and with constant resistance adapter sleeve, get loose, thereby arrive closely, connect.Like this, when drilling rod forward, because the spiral annexation of adapter sleeve can turn tighter and tighter, during drilling rod reversion, spring detent stops that adapter sleeve reverse rotation gets loose, and can bear larger torsional forces.The utility model is easy and simple to handle, and connection and unloading process are very simple, and the sealing ring life-span is longer, and after drilling rod connects, linearity is good, is difficult for getting loose during reversion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, sealing termination, 2, outer polygon joint, 3, adapter sleeve, 4, spring detent, 5, sealed end tail, 6, link tail, 7, connection end.
The specific embodiment
As shown in Figure 1, the utility model is to be provided with link tail 6 in the rear end of hollow drill pipe, on the external diameter of link tail 6, is provided with external screw thread, in the inside that connects tail end, is provided with the inner polygon hole (not shown) of matching with outer polygon joint 2.
For the flimsy situation of the rubber ring that leaks, the utility model is provided with the sealed end tail 5 being connected with link tail 6 in drilling rod, and between sealed end tail 5 and inner diameter wall, space is being set, simultaneously in the sealing termination 1 with rubber sealing boot that arranges at drilling rod front end.When the front end of a drilling rod inserts the inner polygon hole of another root drilling rod, sealing termination 1 is inserted in sealed end tail 5, has avoided damaging the generation of drainage because wearing and tearing cause the sealing ring that seals termination 1, thereby has played the effect of good sealing water.
On drilling rod, be provided with and seal the termination 1 outer polygon joint 2 that is connected.The shape of this outer polygon joint 2 matches with the shape in inner polygon hole, when outer polygon joint 2 be outer quadrangle joint, outer hexagon joint or outside during octagon joint, inner polygon hole corresponds to interior quadrilateral hole, interior hexagonal hole or interior octagon hole, so that the inner polygon hole that outer polygon joint 2 is inserted to link tail 6, the torque resistant power while simultaneously having strengthened drilling rod forward or reverse.
Be arranged on drilling rod and outer polygon joint 2 is connected and diameter is identical with link tail 6 connection end 7.For the non-reversible defect of threaded connection drill stem, the utility model is provided with the external screw thread consistent with link tail 6 rotation directions on connection end 7, and by this external screw thread, is connected with adapter sleeve 3 on connection end 7.And at connection end 7 middle parts, spring detent 4 is set, so that after two drilling rods connections, adapter sleeve 3 is screwed to the middle junction of connection end 7 and link tail 6, simultaneously by spring detent 4, block adapter sleeve 3, the phenomenon that gets loose between the drilling rod causing because of getting loose of adapter sleeve 3 when avoiding drilling rod reversion.
This spring detent 4 includes spring and is fixed on the bayonet lock of spring one end, the other end of spring is fixedly connected on the inside of connection end 7, and bayonet lock is all or part of exposed inside that is arranged on connection end 7 after connection end 7 outsides, spring-compressed when spring original state.
Wherein, before jointed rod, adapter sleeve 3 is tightened and is arranged on connection end 7, now spring detent 4 is compressed in the body of rod, when drilling rod connects, adapter sleeve 3 is screwed to the middle junction of connection end 7 and link tail 6, now, by spring detent 4, in the body of rod of connection end 7, eject and block adapter sleeve 3.External screw thread on link tail 6 and connection end 7 is set to the external screw thread of coarse pitch as required.
