[0030] This utility model proposes a green exploration drilling rig internal pipe protection device.

[0031] like Figs. 1-2 The green exploration drilling rig inner pipe protection device shown includes a connecting strip 1, a fixing mechanism 2, and a lifting mechanism 3. The fixing mechanism 2 is located at one end of the connecting strip 1, and a positioning element is located at the end of the connecting strip 1 away from the fixing mechanism 2. The end of the connecting strip 1 with the positioning element is bent toward the end of the connecting strip 1 with the fixing mechanism 2. The fixing mechanism 2 is used to detachably connect the positioning element. The lifting mechanism 3 is located on the side of the connecting strip 1 away from both ends.

[0032] The connecting strip 1 is connected to the inner pipe through the fixing mechanism 2 and the positioning component, and then connected to the external crane through the lifting mechanism 3, so that the inner pipe and the retrieval device are firmly connected, preventing the inner pipe from separating from the retrieval device when it is tilted, ensuring the normal progress of the project, and ensuring the production safety of the surrounding workers.

[0033] The connecting bar 1 is symmetrically arranged along the lifting mechanism 3, and the lifting mechanism 3 and the connecting bar 1 are detachably connected. The connecting bar 1 is symmetrically arranged along the lifting mechanism 3 to form a U-shape to ensure a stable center of gravity during operation.

[0034] The lifting mechanism 3 includes a lifting ring 31 and a connecting column 32. The lifting ring 31 is connected to one end of the connecting column 32, and the end of the connecting column 32 away from the lifting ring 31 is detachably connected to the connecting bar 1.

[0035] A connecting through hole 14 is provided on the side of the connecting strip 1 away from both ends; the lifting mechanism 3 includes a limiting nut 33, and the end of the connecting column 32 away from the lifting ring 31 is provided with an external thread. The limiting nut 33 is located between the connecting through hole 14 and both ends of the connecting strip 1. The end of the connecting column 32 away from the lifting ring 31 is used to pass through the connecting through hole 14 and the limiting nut 33 for threaded connection. The separate structure of the lifting mechanism 3 and the connecting strip 1 makes it easy for the connecting strip 1 to extend into the inner tube as a hook 13 to lift the fallen cable.

[0036] A first threaded through hole 11 is formed at the end of the connecting strip 1 furthest from the positioning member. The first threaded through hole 11 extends from one end of the connecting strip 1 toward the other end. The fixing mechanism 2 includes a screw 21 and a handle 22. The handle 22 is located on the side of the first threaded through hole 11 furthest from the positioning member. One end of the screw 21 is connected to the handle 22, and the other end of the screw 21 is threadedly connected to the first threaded through hole 11. The handle 22 adjusts the distance between the two ends of the screw 21 extending through the connecting strip 1, so as to facilitate the alignment of the screw 21 and the positioning member after the inner tube is inserted.

[0037] A second threaded through hole 12 is opened at the end of the connecting strip 1 away from the first threaded through hole 11. The second threaded through hole 12 and the first threaded through hole 11 are coaxially arranged. The positioning element includes a positioning bolt 4, which is located on the side of the second threaded through hole away from the first threaded through hole 11. The positioning bolt 4 is threadedly connected to the second threaded through hole 12 and extends to the two ends of the connecting strip 1. Since it is inconvenient to observe the screw 21 after it is inserted into the inner tube, the positioning bolt 4 is inserted into the inner tube first, then the screw 21 is aligned with the inner tube and the handle 22 is rotated so that the screw 21 abuts against the positioning bolt 4, thereby locking the inner tube and the retrieval device. The positioning bolt 4 and the second threaded through hole 12 are threadedly connected, which makes it easy to adjust the distance between the two ends of the connecting strip where the positioning bolt 4 extends, according to the actual use.

[0038] Hooks 13 are respectively installed on one side of the connecting bar 1 away from the two ends of the connecting bar 1, and the hooks 13 are tilted away from the lifting mechanism 3. The lifting mechanism 3 and the connecting bar 1 are separated, and then the external crane is connected through the fixing mechanism 2 and the positioning component. The connecting bar 1 is extended into the well so that the multiple hooks 13 cooperate to hook the cable. Finally, the external adjustment raises the connecting bar 1 so that the cable of the multiple hooks 13 is raised to the outside of the well.

[0039] Each hook 13 is symmetrically arranged along the lifting mechanism 3.

[0040] Specifically, six hooks 13 are provided on the outer side of the connecting strip 1.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
