Referring to fig. 1, according to the utility model discloses a turn over a hoist, should turn over a hoist and include distribution beam 4, upper pulley group 5, lifting rope twine group 6, lower pulley group 7, branch rope roof beam 8, and distribution beam 4 is triangle-shaped's three-terminal for having mutual line, and its first end hangs on crane hook 1, and branch rope roof beam 8 is installed to the second end, and upper pulley group 5 is installed to the third end, and upper pulley group 5 is connected with lower pulley group 7 through lifting rope twine group 6. The pile turning lifting appliance in the embodiment can be used for being matched with a crane hook to be used for pile turning operation, so that a conventional single-hook crane has the pile turning capacity. The distributing beam 4 is provided with three ends which are connected with each other in a triangle, and the weight of the pile 10 can be concentrated on the first hinge shaft 11 which is always balanced relative to the crane hook 1 in the pile overturning operation hoisting stage by being connected with the upper pulley group 5 and the rope distributing beam 8. The distribution beam 4 can rotate around the first hinge shaft 11, and when the stress of the second end and the third end is unbalanced, the distribution beam 4 can correspondingly automatically deflect for a certain angle to enable the pile turning lifting appliance to be balanced in stress, so that the side turning is prevented, and the stability and the safety of pile turning operation are ensured.

In some embodiments, the hoisting rope used for the hoisting rope winding group 6 includes, but is not limited to, a steel wire rope, which has tensile property and flexibility, can change the shape along with the traction mechanism without being damaged in the pile overturning operation hoisting stage and the pile overturning stage, and provides stable tension for hoisting.

The distribution beam 4 can rotate around the balance beam 3 through the first hinge shaft 11, and the distribution beam 4 can automatically adjust the deflection angle through left-right swinging in the hoisting and pile turning stages, so that the distribution beam is automatically adaptive to the stress change of the second end and the third end. If the distribution beam 4 cannot rotate around the balance beam 3 through the first hinge shaft 11, when the second end and the third end of the distribution beam 4 are unbalanced in stress, the distribution beam 4 and/or the balance beam 3 are easily broken, and/or the two sides of the pile-turning hanger are unbalanced in stress, so that the pile-turning hanger is turned on one side. Therefore, the distributing beam 4 can maintain the stability of the gravity center of the whole body of the lifting appliance and the lifted object in the lifting stage and the pile overturning stage of pile overturning operation, so that the single-hook pile overturning process keeps balance and protects the stress unit from being damaged.
