DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0022] Example one:

[0023] Please refer to Figures 1-4The utility model provides a kind of self-locking coring auxiliary device, including core tank bracket 1 and self-locking embrace clamp lifting mechanism 4, self-locking embrace clamp lifting mechanism 4 includes hook 41 and two first connecting rods 42, two first connecting rods 42 are rotationally connected in upper side, hook 41 is arranged at the rotary connection of first connecting rod 42, and first connecting rod 42 lower side end is rotationally connected with first fixed connecting shaft 45.

[0024] Core tank 2 is fixedly connected on core tank bracket 1.

[0025] Self-locking embrace clamp lifting mechanism 4 is arranged on the upper side of core tank 2.

[0026] Self-locking embrace clamp lifting mechanism 4 is arranged on the upper side of core tank 2.

[0027] Self-locking embrace clamp lifting mechanism 4 also includes two second connecting rods 43, and the second connecting rod 43 is rotationally connected with the first connecting rod 42 by the first fixed connecting shaft 45, the second connecting rod 43 is rotationally connected with the second fixed connecting shaft 46 in the middle, and the two second connecting rods 43 are crossed in the middle and are fixedly limited by the second fixed connecting shaft 46 at the crossing.

[0028] The inner side wall of second connecting rod 43 is fixedly connected with anti-skid clamp block 44, and core barrel 3 is clamped in the inner side of anti-skid clamp block 44.

[0029] Working process: during coring operation, core barrel 3 is hung below self-locking embrace clamp lifting mechanism 4, is pulled upward by traction, so that first fixed connecting shaft 45 and second fixed connecting shaft 46 rotate, first connecting rod 42 and second connecting rod 43 are both rotated to the inner side, anti-skid clamp block 44 is used to clamp the outer side of core barrel 3, and core barrel 3 is locked;

[0030] According to the position of core tank 2 division, the hook 41 can be hung by crane, so that the overall self-locking embrace clamp lifting mechanism 4 and core barrel 3 are controlled to move in horizontal direction;

[0031] Through the core tank bracket 1 outside core tank 2, it can be ensured that the core does not leak to the ground when knocking the core, and the scattered core can be artificially loaded into core tank 2 on core tank bracket 1, to ensure the integrity and originality of the core.

[0032] In the case that high-pressure water cannot be used to flush the core, coring operation only needs one person to control the controller and knock the core, and the coring efficiency is high.

[0033] By adjusting the position of self-locking embrace clamp lifting mechanism 4, it can be ensured that the knocked core falls into the corresponding position of core tank 2, without artificially adjusting the side wall after loading into core tank 2.
