Abstract

The utility model belongs to the drill rod coupling piece of a drilling rig. Ring bodies with a gap or a protrusion are arranged on the upper and the lower ends of a drill stem, a screw thread is arranged on the outside of the ring body with the gap, and a nut is arranged on the outside of the ring body with the protrusion. The screw thread of the nut is matched with the external screw thread on the ring body. The other end of the nut is sheathed on the outside of the ring body with the protrusion, and end surface in the nut contacts the end surface of the ring body with the protrusion. The utility model has the advantages of convenient installation and operation and firm combination, etc.

Description

Jointing device for drilling rod
The utility model relates to the drilling rod connector of geological drilling machine, specifically a kind of by the attaching nut with recessed connector that couples together with lug of two drill rod ends.
Having a kind of in the existing drill rod connector is to connect interior external gear respectively in the end of two drilling rods; utilize the gear transmission moment of torsion, the shortcoming of this pattern is 1, the internal gear manufacturing cost is higher, 2, the tight zero-clearance of the engagement between the gear; usually can directly contact again in the gap with silt; when drilling rod turns round, cause the wearing and tearing of tooth easily, from and strengthened the gap; finally cause losing efficacy; so application life is shorter, and the price of every drilling rod is everlasting about several ten thousand yuan, wastes bigger.3, because the tooth of internal gear is more, drilling rod after all can be very not vertical when butt joint up and down again, and therefore, installing and locating is difficulty quite.
The purpose of this utility model is that a kind of connection of design is reliable convenient, drill rod connector easy to manufacture, rational in infrastructure.
Its main technical schemes is that this connector comprises drilling rod (8) and following drilling rod (1), the ring bodies (6) that the band projection is arranged in the end of last drilling rod (8) or following drilling rod (1), in the end of descending drilling rod (1) or last drilling rod (8) the notched ring bodies (2) that cooperates with ring bodies (6) is arranged, ring bodies has external screw thread on (2), the outside of ring bodies (6) is with nut (5), the end of thread of nut (5) cooperates with external screw thread on the ring bodies (2), there is step the other end inside of nut (5), and the end face of step contacts with the end face of ring bodies (6); Ring bodies (6) welds with drill rod end respectively with ring bodies (2), and fastening with (3) location by straight pin (7); Last drilling rod (8) or following drilling rod (1) stretch in the ring bodies (2), and place sealing ring (4) in the contact position of drilling rod and ring bodies.
The utlity model has following good effect: 1, owing to utilize nut to transmit pulling force between drilling rod and the drilling rod, transmit torsion between drilling rod and the drilling rod with projection and breach, the force-bearing situation of drilling rod is improved, thereby has reduced the wearing and tearing of drilling rod, improved application life.The 2nd, when butt joint, have only two taper convex-concave tenons to participate in engagement is installed on two drilling rods, fairly simple, and also before not meshing, drilling rod stretches into the endoporus of notched ring bodies, makes guide-localization, makes when installing also more convenient.

Claims (3)

1, drill rod connector, comprise drilling rod (8) and following drilling rod (1), it is characterized in that the protruding ring bodies (6) of band being arranged in the end of last drilling rod (8) or following drilling rod (1), in the end of descending drilling rod (1) or last drilling rod (8) the notched ring bodies (2) that can cooperate with ring bodies (6) is arranged, ring bodies has external screw thread on (2), the outside of ring bodies (6) is with nut (5), the end of thread of nut (5) cooperates with the external screw thread of ring bodies (6), there is step the other end inside of nut (5), and the end face of step contacts with the end face of ring bodies (6).
2, connector according to claim 1 it is characterized in that ring bodies (6) and ring bodies (2) weld with drill rod end respectively, and (7) and (3) location is fastening slightly by cylinder.
3, connector according to claim 1 is characterized in that drilling rod (8) or following drilling rod (1) stretch in the ring bodies (2), and places sealing ring (4) in the contact position of drilling rod and ring bodies.
