(S21).

Thereafter, the pair of drilling core barrels are disposed in the drilling core barrel support part so as to be horizontal in each direction (S22). In this case, in order to support the drilling core barrel 2 in a horizontal direction, a pair of drilling core barrel connecting devices 1 may support one drilling core barrel 2, and a pair of drilling core barrels 2 may be used. This branch can be mounted to the drilling core barrel rotating part 200 by selecting the hole 101 to match the diameter.

In addition, according to the diameter of the drilling core barrel (2) after adjusting between the other end of the first support arm 110 and the second support arm (120) constituting the drilling core barrel support portion 100, the drilling core barrel (2) ) Can be effectively supported on the drilling core barrel 2 having various diameters.

And it is possible to adjust the height of the pair of drilling core barrel (2) by the piston jack method by the height adjustment control unit 410 (S23). Here, the height adjustment control unit 410 for adjusting the height of the pair of drilling core barrel (2) is controlled by the user, electrically connected to the drilling core barrel height adjustment unit 300 is a straight reciprocating piston unit 400 It is possible to move, and each of the pair of drilling core barrel 2 can be adjusted in height so that the male screw (2a) and the female screw (2b) correspond.

At this time, the linear reciprocating motion of the piston 400 may be generated due to hydraulic pressure or pneumatic pressure.

Therefore, even when working on a non-uniform vessel or workshop, it is possible to horizontally maintain the drilling core barrel (2), it is possible to match the height of the pair of drilling core barrel (2).

Next, the drilling core barrel 2 may be rotated and coupled by contacting the drilling core barrel rotating part 200 (S24). In this case, the force for rotating the drilling core barrel may be a manpower or electric power.

As described above, when the drilling core barrel connecting device and the drilling core barrel connecting method using the same according to an embodiment of the present invention and other embodiments are used, drilling is formed in a V-shape to be applied to drilling core barrels having various diameters. There is an advantage that the core core support can be easily connected by supporting the core core barrel pair, and by rotating the core core barrel with the drilling core barrel rotation.

In addition, by adjusting the height of the drilling core barrel support by the drilling core barrel height adjusting unit has the advantage that can be connected to the drilling core barrel even when the bottom of the vessel or workshop is not uniform.

In addition, by guiding the rotation of the drilling core barrel in direct contact with the drilling core barrel in the drilling core barrel rotating portion, there is an advantage that can effectively rotate the heavy-weight drilling core barrel.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. will be. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
