Abstract

The invention provides a vertical Christmas tree land lifting tool. The vertical Christmas tree land lifting tool comprises a body, a push rod locking assembly, and a claw connection assembly; the body is provided with an accommodating space for at least holding the upper end of a vertical Christmas tree, the outer wall of the body is provided with a radial through hole penetrating into the accommodating space; the push rod locking assembly is mounted in the radial through hole and can slide to the direction of the accommodating space, the push rod locking assembly is provided with a locking position connected with the vertical Christmas tree in a clamping mode and an unlocking position retracted into the radial through hole; and the claw connection assembly is arranged on the body, and the claw connection assembly can move in the axial direction of the body and is connected with a driving rod on the vertical Christmas tree in a clamping mode. The vertical Christmas tree land lifting tool has the beneficial effects that the locking force on the vertical Christmas tree can be increased by arranging the push rod locking assembly and the claw connection assembly, and the stability of hoisting during hoisting is ensured.

Description

technical field [0001] The invention relates to the field of lifting devices, in particular to an onshore lifting tool for a vertical Christmas tree. Background technique [0002] The subsea vertical Christmas tree onshore lifting tool is an installation tool used in conjunction with the subsea vertical Christmas tree tree structure. It can be applied in the testing and installation stage of the subsea tree, and it can complete the installation of the subsea tree together with the subsea tree body feeding tool. In the prior art, the vertical tree is generally moved by direct hoisting or truck-loaded transportation. [0003] Direct hoisting is generally to directly bind the above-mentioned vertical oil tree through steel wires or slings, and move the vertical tree through hoisting components such as a crane. [0004] Chinese utility model patent, authorized announcement number CN202953143U, authorized announcement date on May 29, 2013, discloses a deep-sea drilling Christma...
