Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.
As shown in fig. 1, the utility model provides a drilling rod convenient to dismantle, on the drilling rod was fixed in drive drilling rod pivoted machine through connecting block 100, including the body of rod 200, screwed pipe 300 and liner 400, the one end and the connecting block 100 threaded connection of the body of rod 200, on the outer wall of the body of rod 200, the outer wall and the screwed pipe 300 threaded connection of the body of rod 200, liner 400 cover was located on the body of rod 200, and both ends respectively with connecting block 100 and screwed pipe 300 butt, the screw direction on the connecting block 100 is opposite with the screw direction on the screwed pipe 300, the screw direction of screwed pipe 300 is opposite with the rotation direction of the body of rod 200.
Wherein, one end of the rod body 200 is provided with a first external thread 210, the connecting block 100 is provided with a first internal thread 110, the first external thread 210 is in threaded connection with the first internal thread 110, the outer wall of the rod body 200 is provided with a second external thread 220, the inner wall of the threaded pipe 300 is provided with a second internal thread 310, the second external thread 220 is in threaded connection with the first internal thread 110, and the rotation directions of the first internal thread 110 and the second internal thread 310 are opposite.
Preferably, the first external thread 210 has an outer diameter no greater than that of the second external thread 220, facilitating installation of the threaded pipe 300.
Preferably, the spacer 400 is a rubber ring, and when the threaded pipe 300 and the rod body 200 tend to move relatively, the spacer 400 is pressed, thereby canceling a part of the force acting on the threaded pipe 300 and the rod body 200.
When the connecting device is installed, the threaded pipe 300 is firstly sleeved on the rod body 200, the second internal thread 310 in the threaded pipe 300 is in threaded connection with the second external thread 220 on the rod body 200, the gasket 400 is sleeved on the rod body 200, the gasket 400 is opposite to the connecting block 100, the first external thread 210 of the rod body 200 is in threaded connection with the first internal thread 110 on the connecting block 100, the connecting block 100 is connected with one side of the gasket 400 in an abutting mode through rotation, and the other side of the gasket 400 is connected with the threaded pipe 300 in an abutting mode.
The working process is as follows: the reamer drives the connecting block 100 to rotate and drives the rod body 200 to rotate, for convenience of understanding, the rotation direction of the connecting block 100 is taken as clockwise, the rotation direction of the connecting block 100 is clockwise, the rod body 200 is driven to rotate clockwise, the rotation direction of the first internal thread 110 is the same as the rotation direction of the connecting block 100, namely, the rotation direction of the first internal thread 110 is clockwise, in order to achieve the effect of screwing more and more, the rotation direction of the first external thread 210 is counterclockwise, the rod body 200 rotates clockwise, the threaded pipe 300 is driven to rotate clockwise, the rotation direction of the second external thread 220 is the same as the rotation direction of the rod body 200, the rotation direction of the second external thread 220 is clockwise, in order to achieve the effect of screwing more and more, the rotation direction of the second internal thread 310 is counterclockwise, when one end of the rod body 200 receives impact and friction, the rod body 200 has a tendency of counterclockwise rotation, at this time, the rotation direction of the second internal thread, under the movement trend of the rod body 200, the rod body 200 tends to rotate relative to the threaded pipe 300, however, one side of the threaded pipe 300 is abutted to the connecting block 100 through the gasket 400, the movement trend is prevented, so that the second internal thread 310 and the second external thread 220 are damaged firstly, and when the drill rod is damaged, the rod body 200 and the threaded pipe 300 are completely disassembled and replaced.
Be different from the condition of prior art, the utility model discloses a set up the body of rod 200, screwed pipe 300 and liner 400, and the screw thread direction of screwed pipe 300 is opposite with the screw thread direction on the connecting block 100, and the screw thread of screwed pipe 300 revolves to opposite with the rotation direction of the body of rod 200, when the body of rod 200 received frictional force and impact force, body of rod 200 has relative pivoted trend with screwed pipe 300, screwed pipe 300 passes through liner 400 and connecting block 100 butt this moment, thereby offset this trend, so the foremost damaged is the screw thread of screwed pipe 300 and body of rod 200 junction, thereby the screw thread of connecting block 100 with the body of rod 200 junction has been protected, be convenient for pull down the body of rod 200 from connecting block 100.
It should be noted that the above embodiments belong to the same utility model concept, and the description of each embodiment has its emphasis, and the description of each embodiment is not described in detail, and reference may be made to the description of other embodiments.
