[0012] (Three) beneficial effects

[0013] Compared with the prior art, the automatic unhooking beam has the following beneficial effects:

[0014] The automatic unhooking beam, through the cooperation of the balance beam, the lifting lug, the reinforcing limiting plate, the adjusting block, the lifting ring plate, the scale ruler and the adjusting handle, a person can hold the adjusting handle by matching the scale ruler during use, so as to drive the lifting ring plate to be clamped into the adjusting block groove with a corresponding interval, thereby playing a role of adjusting the lifting interval when the beam is lifted. When there is no rope on the surface of the hook or the hoisted heavy object reaches the position where the rope needs to be automatically unhooked and loosened, the reinforcing reset spring is in a contraction state at this time, drives the second limiting roller shaft to move downward in the lifting limiting groove, makes the hook be lifted up under pressure, and makes the rope automatically separate from the hook. When the heavy object is lifted, the rope is hung on the hook, the hook moves downward vertically under the influence of gravity, makes the second limiting roller shaft stretch downward in the lifting limiting groove, and the reinforcing reset spring is in a stretching state at this time. The second limiting roller shaft goes up and down, and the hook block is attached to the hook to form a closed loop, thereby playing a role of automatically unhooking the beam according to the use requirement.
