The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
As shown in Figure 1, a kind of drilling rod described in the utility model comprises drilling rod body 1, female joint 2, male joint 3, pin 4, and described drilling rod body 1 is the screwed column structure of hollow and two ends; Described female joint 2 is hollow and the screwed column structure of an end, and is fixed in an end of described drilling rod body 1 by screw thread, and its end away from drilling rod body 1 is provided with " L " type fixed structure 5; Described male joint 3 is hollow and the screwed column structure of an end, the other end of drilling rod body 1 is fixed in described male joint 3 by screw thread, its end away from drilling rod body 1 is provided with one or more annular groove 6, described male joint 3 middle parts are provided with a locating hole, and described pin 4 is fixed in the locating hole by screw thread.
Wherein, described " L " type fixed structure 5 is made of slideway and a circular hole, described slideway is along the axial direction of female joint, the axis of described slideway and the circular hole center of circle be wired to the right angle, described pin 4 comprises the head of a nail and nail body, described nail body is embedded in the male joint, and the described head of a nail is exposed to outside the male joint.
When a joint drilling rod is connected with another joint drilling rod, by the male joint 3 of a joint drilling rod being inserted the female joint 2 of another joint drilling rod, and the mode that the head of a nail that inserts the pin 4 in the male joint 3 of female joint 2 is stuck in the circular hole of " L " type fixed structure 5 of described female joint 2 connects.
Wherein, it is that the 1500MPa stainless steel material is made that described male joint, female joint and pin adopt yield limit.The critical component of the drilling rod of being made by this material has effectively alleviated the overall weight of drilling rod.
In order to make male joint 3, female joint 2 and more firm difficult drop-off of being connected of drilling rod body 1, described female joint 2 and male joint 3 scribble screw thread glue with the connection of thread of drilling rod body 1.
Be provided with " O " RunddichtringO in the described annular groove 6, in drilling process, play the effect of sealing drilling rod junction circulation of fluid.
The below briefly introduces the operating principle of drilling rod:
During jointed rod, make the head of a nail of the pin 4 of the first drilling rod 101 aim at the slideway of " L " type fixed structure 5 of the second drilling rod 102, then draw bottom to slideway along slideway, at this moment, the male joint 3 of the first drilling rod 101 has been inserted in the female joint 2 of the second drilling rod 8, then fixes the second drilling rod 102, and the first drilling rod 101 is turned clockwise, the head of a nail of the pin 4 of the first drilling rod 101 is stuck in the circular hole of the second drilling rod 102 " L " type fixed structure 5, has then finished the connection of two joint drilling rods.
During lower brill, the first drilling rod 101 to pressing down, is passed to downforce by the pin 4 on the first drilling rod 101 " L " type fixed structure 5 of the second drilling rod 102, thus with the second drilling rod 102 to pressing down.
When creeping into, the first drilling rod 101 turns clockwise, and moment of torsion is passed to " L " type fixed structure 5 of the second drilling rod 102 by the pin 4 on the first drilling rod 101, turns clockwise thereby drive the second drilling rod 102.
Carry when boring, the first drilling rod 101 is upwards carried, lifting force is passed to " L " type fixed structure 5 of the second drilling rod 102 by the pin 4 on the first drilling rod 101, thereby the second drilling rod 102 is upwards carried.
During dismounting drilling rod, fix the second drilling rod 102, then the first drilling rod 101 is rotated counterclockwise, the pin 4 that makes the first drilling rod 101 is threaded to the slideway bottom of " L " type fixed structure 5 in the circular hole of " L " type fixed structure 5 of the second drilling rod, then the slideway along " L " type fixed structure 5 is pulled outwardly the first drilling rod 101, until the female joint 2 of the male joint 3 of the first drilling rod 101 and the second drilling rod 102 breaks away from fully, then finished the dismounting of drilling rod.
It is that the stainless steel material of 1500MPa is as the material of drilling rod key position that a kind of drilling rod described in the utility model has been selected yield limit, all be to adopt this material to make such as male joint, female joint and pin, when guaranteeing that drilling rod has sufficient intensity, alleviated the weight of drilling rod, the simultaneously distinctive structure of this drilling rod and plug-in connected mode have been reduced the handling speed of drilling rod greatly.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
