[0047] The following briefly describes the use of the lifting tooling provided in this embodiment.
[0048] Hang the lifting ring 17 on the hook of the overhead equipment, start the overhead equipment, insert the lifting member 10 into the slot 21 of the lifting block 20 until the lifting member 10 extends into the groove of the lifting block 20. At this time, pull the pull ring 22, drive the first sliding rod 3 to move through the first pull rope 9, so that the second free end of the first sliding rod 3 exceeds the sharp corner between adjacent teeth of the first ratchet 4, and then let go. Under the elastic force of the first elastic member 6, the first ratchet 4 is rotated 90°, thereby driving the first suspension rod 5 to rotate 90°. (It can be observed that the indicator 19 has rotated 90°, and the indicator 19 is perpendicular to the suspension beam frame 2, proving that the first suspension rod 5 has rotated 90°). At this time, the lifting member 10 rotates accordingly and can cooperate with the lifting block 20 to abut, and the workpiece 1 can be hoisted. After the workpiece 1 is stably placed at the designated position, the overhead equipment descends, pull the pull ring 22 again, and finally continue to rotate the first suspension rod 5 by 90°. The lifting member 10 rotates accordingly to facilitate its removal from the groove of the lifting block 20. At this time, the indicator 19 is parallel to the suspension beam frame 2, the overhead equipment rises, and the lifting member 10 disengages from the lifting block 20, thereby separating the lifting tooling from the workpiece 1 to complete the entire hoisting process.
