Detailed Description
The following detailed description of the present invention is provided with reference to the accompanying drawings and examples, but not to be construed as limiting the present invention in any way.
Referring to the attached drawings, the three-edged drill rod suitable for being grabbed by a manipulator mainly comprises a drill tail 3, a drill warehouse 1, a rod body and a centering rib 4. The drill tail 3 is a male joint of the drill rods and is provided with a tapered external thread, the drill magazine 1 is a female joint of the drill rods and is provided with a tapered internal thread, and the drill tails 3 on the two drill rods are connected with the drill magazine 1 through the threads, so that the drill rods can be connected end to end; the rod body is used for transmitting torque during drilling, the triangular rod body 2 made of triangular tubes is adopted, and the slag discharging efficiency can be effectively improved when the rod body rotates by utilizing the characteristics of the triangular rod body 2; the triangular rod body 2 can be divided into three planes and three arc surfaces in the circumferential direction, the planes and the arc surfaces are alternately arranged, the drill tail 3 and the drill magazine 1 are both made of round tubes, one end of the drill tail 3 and one end of the drill magazine 1, which is connected with the triangular rod body 2, are complete circles, and one end of the triangular rod body 2 is not a circle, so that when the drill tail 3 and the drill magazine 1 are welded, the contact area of the welding part is small, welding forming is not facilitated, and the torque transmitted after welding is limited, therefore, hot punching needs to be carried out on the end part of the triangular rod body 2, so that the end part of the triangular rod body is a circle with the same diameter as that of the; during welding, the transition section 5 formed by punching the end part of the triangular rod body 2 and the connecting end of the drill magazine 1 or the drill tail 3 are welded together by friction welding to form a drill rod.
Because the inner edge of the gripper is an inner arc when the mechanical gripper grabs a drill rod, the center of the drill rod and the center of the inner arc of the gripper are not concentric due to the shape of the triangular rod body 2, which affects the grabbing stability and the automatic connection of the drill rod, the length direction of the centering rib 4 is parallel to the axial direction of the triangular rod body 2, and the top surface of each centering rib 4 is processed into an arc surface, the radius of the arc surface is equal to the radius of the circumscribed circle of the cross section of the grabbing position of the manipulator of the triangular rod body 2, as shown in fig. 3, so that a plurality of arc surfaces matched with the inner arc of the gripper on the manipulator are formed at the grabbing position of the manipulator on the drill rod, including the top surfaces of the three centering ribs 4 and the three arc surfaces on the triangular rod body 2, which are alternately distributed, which is beneficial to the centering of the drill rod when the manipulator grabs the, the stability of the drill rod after being grabbed is kept, so that the head-to-tail connection of the follow-up drill rod is facilitated.
In order to ensure the sealing performance of the connection position of the drill rod, a sealing groove is formed in the front end of the threaded hole in the drill magazine 1 along the circumferential direction of the threaded hole, a rubber sealing ring is fixedly arranged in the sealing groove, and further, a conical head capable of extruding the sealing ring can be arranged at the front end of the drill tail 3.
After a section of drill rod is detached, in order to avoid water leakage of the drill rod, a water closing device is further arranged in the drill base 1 of the drill rod, when the drill tail 3 of the drill rod is inserted into the drill base 1, the water closing device is opened, the two drill rods are communicated to realize water flowing, and after the drill tail 3 is screwed out of the drill base 1, the water closing device is closed to realize water closing. The structure of the water closing device is described in the utility model patent with the publication number of CN 203321348U.
The above embodiments are only intended to illustrate the technical solution of the present invention and not to limit the same, and it should be understood by those of ordinary skill in the art that the embodiments of the present invention can be modified or replaced with equivalents with reference to the above embodiments, and any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention are all within the scope of the claims of the present application.
