Abstract:
1. An automated shackle assembly comprising: a shackle body having an open part allowing a part of a steel structure to be inserted into the open part and to be supported by the shackle body; a first shackle pin, which opens or closes the open part a first elastic member for providing elastic force required for opening the open part by the first shackle pin; a protrusion for holding the first shackle pin in a closed state; a second shackle pin, which makes contact with the first shackle pin so as to press the first shackle pin to close the open part a vertical movement member, which is arranged on the shackle body and is vertically movable, the vertical movement member passing through a first open part included in one side of the first shackle pin and being engaged with one side of the second shackle pin when the vertical movement member moves downward in a state where the open part has been closed in such a manner that the second shackle pin presses the first shackle pin, thereby maintaining the closed state of the open part, the vertical movement member releasing the closed state of the open part when the vertical movement member moves upward in the closed state of the open part; a second elastic member for providing elastic force required for moving the second shackle pin in a direction where the open part is opened when the vertical movement member moves upward; and a third shackle pin, which is arranged between the first shackle pin and the second shackle pin and receives force from the second shackle pin, which is moved by obtaining elastic energy provided from the second elastic member when the open part is opened, thereby releasing a held state of the protrusion.
