Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1, as shown in fig. 1 to 3:

a novel flange hanger comprising: the crane hook hanging head comprises a crane hook hanging head 1, a telescopic sleeve 2, a hook 5, a pin shaft 6, a triangular support base shaft 10 and a flange 11, wherein the telescopic sleeve 2 is connected to the bottom end of the crane hook hanging head 1, the telescopic sleeve 2 is in sliding sleeve connection with the triangular support base shaft 10, a first connecting block 14 and a second connecting block 15 are respectively arranged on two sides of the bottom end of the telescopic sleeve 2, the second connecting block 15 is provided with an automatic locking hook 3, the bottom end of the triangular support base shaft 10 is sequentially provided with a first shaft shoulder 12 and a second shaft shoulder 13, the triangular support base 9 is welded to the bottom end of the triangular support base shaft 10, an adjusting hole 8 is formed in one side of the triangular support base 9, the hook 5 is connected with the adjusting hole 8 through the pin shaft 6, the hook 5 is provided with a chain 4, the other end.

In a preferred technical scheme of this embodiment, the self-locking hook 3 is movably connected with the second connecting block 15 through a self-locking hook pin 17.

According to a preferable technical scheme of the embodiment, the hook 5 is provided with a hook hole 18, the first connecting block 14 is provided with a chain connecting hole 16, and one end of the chain 4 is connected with the hook hole 18 while the other end is connected with the chain connecting hole 16.

In the embodiment, the telescopic sleeve 2 freely falls, the self-locking hook 3 is hung on the triangular support seat shaft 10, the chain 4 is in a loose state, the hook 5 is not contacted with the flange 11 under the action of gravity (as shown in figure 1), the telescopic sleeve 2 continuously falls, namely the self-locking hook 3 falls to the second shaft shoulder 13, the crane is quickly lifted to drive the telescopic sleeve 2, the self-locking hook 3 rises to the first shaft shoulder 12 through inertia until the chain 4 is tightened, the adjusting screw rod 7 is pressed against the inner wall of the flange 11, when the friction force is larger than the dead weight of the flange 11, the flange 11 is lifted, the flange 11 is adjusted to a proper position, the crane falls down, the telescopic sleeve 2 falls down, the chain 4 is loosened, the adjusting screw rod 7 is separated from the inner wall of the flange 11, when the self-locking hook 3 reaches the first shaft shoulder 1, the self-locking hook 3 is hooked with the triangular support seat shaft 10 again, the telescopic sleeve 2 is lifted, and the whole lifting appliance is lifted to be separated from the flange 11.
