Definitions

  • the apparatus comprises a pair of pivotal arms, a hydraulically actuated sliding rod supported by each arm, a pulley on the end of each sliding rod, an actuating rope passing over each pulley and attached to a weight, and a winch sup ported on each arm for winding the actuating ropes, located on the pusher for lifting a weight connected to the lashing rope and engaging the weightwith a bitt provided on the barge, and a winch for winding the lashing rope.
  • the present invention relates to an apparatus for lashing a pusher with a barge.
  • FIG. 1 is a rear view of the pusher and the barge connected by a lashing apparatus in accordance with the present invention
  • FIG. 2 is a plan view of the lashing apparatus
  • FIG. 3 is a perspective view of the lashing apparatus
  • FIG. 4 is a perspective view of bitts used in the lashing apparatus.
  • the barge 1 has a notch 2 into which the pusher 3 is inserted.
  • the pusher 3 is provided with a winch for winding the rope 8 having a pulley 7 at the end thereof.
  • the lashing rope 5 is to be engaged with the pulley 7 and rollers 6 provided on the deck of the pusher and engaged with bitts 9 of the barge l.
  • the pusher 3 is provided with a pair of arms 11 of the lashing apparatus in accordance with the present invention at board sides above the bitts 9.
  • Each of the arms 11 comprises a triangular member 11a rotatably mounted on horizontal shafts of hinges l2 and held by the rope 21 connected between the drum of the winch 20 and the pin provided on the end of the member 11a.
  • a sliding rod 11b is slidably provided in the arm 11 and connected to the piston rod 14a of the oil hydraulic cylinder 14.
  • Actuating rope 17 is connected to the drum of the winch 16 provided on the triangular member 11a and passed through the pulley provided at the end of the sliding rod 11b and connected to a weight 18 provided at the end of the lashing rope 5.
  • Each of bitts 9 comprises a pair of posts 9a which have guide plates 9b and 9c.
  • the guide plate 9b are secured on the top of the posts 9a for guiding the rope 5 into the space between the posts and guide plates 9c are secured to the side face of the post and the deck plate for guiding the weight 18 toward the posts.
  • each arm 11 is projected above the bitt 9.
  • the arm is held in the horizontal position by operating the winch 20 and the weight 18 is located in the position above the bitt 9 by operating the winch 16. Thereafter, the weight 18 is lowered so that the weight may be positioned on the deck of the barge 1 between the guide plates 9c and the lashing rope 5 may be inserted between the posts 9a. Then, the lashing rope 5 is tensioned by operating the winch 10 to engage the weight with the posts 9a.
  • the arm 11 is rotated to the upper position by operating the winch 20 as shown by the dotted line in FIG. 1 and the rope 17 is loosened. Thus, the lashing is completed.
  • each of the arm 11 is lowered to the horizontal'position and the lashing rope 5 is loosened. Then, the weight 18 is lifted to remove the lashing rope 5 from the bitt 9 and the arm 11 is rotated to the upper position. Thus, the pusher 3 can be removed from the barge 1'.
  • the present invention provides the lashing apparatus whereby lashing can be easily and safely performed without the lashing work of the operator on the barge.
  • An apparatus for lashing a pusher with a barge comprising a pair of arms provided on board sides of said pusher, each of said arms being supported to be rotated about a horizontal shaft, having a sliding rod, and having a hydraulic cylinder to project said sliding rod from the end of the arm, means for rotating said arm about the horizontal shaft, a pulley provided on the end of said sliding rod, an actuating rope passing through said pulley, a winch provided on the arm for winding the actuating rope, a weight connected to the end of the actuating rope, a lashing rope connected to said weight, means on the pusher for winding said lashing rope, and a bitt for engaging said weight on the barge.
