Chain stopper for chain puller |
摘要 |
A chain puller for use in marine salvage that includes a chain pulling platform having linearly disposed first and second chain stoppers. Each chain stopper includes a pair of pivotal doors that permit the passage of a chain in one direction while stopping the action of a chain moving in the opposite direction. The action on the pivotal doors uses gravity for vertical alignment. The pivotal doors are spaced apart the distance of a vertical chain-link in the static position and are pivotally spread apart to permit movement of the chain in one direction in the dynamic position. |

1. A chain puller that includes at least one chain stopper and a chain used with the chain puller, said chain having vertically and horizontally disposed links when used with said chain puller, said links having thickness comprising:
rigid base plate that can be fastened in place; chain that can be attached to an object to be pulled; first chain stopper rigidly connected to said rigid base plate; second chain stopper moveably connected to said rigid base plate and strategically placed relative to said first chain stopper in the same plane so that a chain can pass through said first chain stopper and said second chain stopper in a straight line; said first chain stopper including a pair of rectangular door support plates, each door support plate having a top, a bottom, and parallel sides rigidly fixed together and rigidly fixed to said rigid base plate base and spaced apart at an angle to each other, and first and second “L”-shaped pivotal doors mounted on one vertical side of each of said door support plates, the “L”-shaped doors being spaced apart by the thickness of a vertical chain-link in the chain lock position; said second chain stopper including a second pair of angled door support plates rigidly fixed at one end to said rigid base plate and spaced at least the width of the horizontal chain-link, and first and second “L”-shaped pivotal doors mounted on the back side of said angled support plates, said “L”-shaped pivotal doors being spaced apart by the thickness of a vertical chain-link; and said second chain stopper connected to a hydraulically actuated cylinder and piston for moving said second chain stopper in a first direction and reciprocally in a second direction based on the activation of said hydraulically actuated cylinder and piston. |
