Pin and Shackle Assembly

Introduction

A shackle, also known as a gyve, is a U-shaped piece of metal secured with a clevis pin or bolt across the opening, or a hinged metal loop secured with a quick-release locking pin mechanism. They are used as a connecting link in all manner of rigging systems, from boats and ships to industrial crane rigging. Disclosed is a shackle assembly used for delivering a steel structure in a construction field, the shackle assembly including a shackle body, first, second, and third shackle pins, first and second elastic means, a vertical movement mean, and a control means. Thanks to the plurality of shackle pins and the plurality of elastic means, the shackle assembly can reduce its weight and manufacturing cost. Also, in spite of the light weight and the low cost of the shackle assembly, stability and efficiency in its working can be sufficiently secured (Edwards, 1988).

Claims

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 223 in such a manner that the first shackle pin linearly moves while intersecting the open part of the shackle body so as to support the steel structure. 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 223 when the second shackle pin moves in a direction where the open part is closed.

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 (Edwards, 1988). 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.
