[0047] The present application describes a torsion block lifting construction device. When lifting the torsion block 8, the first chain 11, the second chain 12, the fourth chain 14 and the third chain 13 are arranged in sequence along the circumference of the torsion block 8; then the first chain 11 is passed under the first protrusion 81 on one side, and the first latch 65 is passed through the first male connector 61 and the first female connector 62 to connect the first male connector 61 and the first female connector 62, and the third chain 13 is passed under the first protrusion 81 on the other side, and the second latch 95 is passed through the second male connector 91 and the second female connector 92 to connect the second male connector 91 and the second female connector 92; then the first hoist 4 and the second hoist 5 are lifted, so that the first chain 11, the second chain 12, the third chain 13 and the fourth chain 14 lift the torsion block 8. At this time, the first lifting rope 21 and the second lifting rope 22 are both in a relaxed state; after that, when the twist block 8 is lifted to the target position, the first sling 4 is continued to be lowered for a distance, so that the first chain 11, the second chain 12, the third chain 13 and the fourth chain 14 are in a relaxed state; then the second sling 5 is lifted, so that the first lifting rope 21 drives the first pin 65 to disengage from the first male connector 61 and the first female connector 62; then the second sling 5 is continued to be lifted, so that the second lifting rope 22 drives the second pin 95 to disengage from the second male connector 91 and the second female connector 92; then the first sling 4 is lifted, so that the first chain 11, the second chain 12, the third chain 13 and the fourth chain 14 are all disengaged from the twist block 8, and the entire untying process does not require manual participation, avoiding the safety risks of the untying process to personnel.
