Detailed Description

With reference to fig. 1-8, the present embodiment provides a lifting appliance for macroscopic corrosion inspection of a rotating member, including a fixed hook 1 and a movable hook 2, a side surface of the fixed hook 1 contacts a side surface of the movable hook 2, the fixed hook 1 includes a fixed rod 14 and a fixed hook 3 disposed at a bottom of the fixed rod 14, the movable hook 2 includes a movable rod 15 and a movable hook 16 disposed at a bottom of the movable rod 15, and both the fixed hook 3 and the movable hook 16 are used for hooking a part to be corroded.

The fixed rod body 14 is provided with a plurality of fixing holes 4, the movable rod body 15 is provided with a plurality of adjusting long holes 5 matched with each fixing hole 4, the adjusting bolts 6 penetrate through the corresponding fixing holes 4 and the adjusting long holes 5, and the fixed hook 1 is connected with the movable hook 2 through the adjusting bolts 6. When the adjusting bolt 6 is loosened, the fixed hook 1 and the movable hook 2 are both in a state of being movable in a relative vertical direction along the adjusting long hole 5. When the adjusting bolt 6 is tightened, the fixed hook 1 and the movable hook 2 are in a relative immovable state.
