Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding and ship maintenance, and specifically relates to an installation mechanism for a towing wire rope in a shipyard and a using method thereof. Background Art

[0002] A floating dock is an engineering ship used for ship repair and shipbuilding. According to its operation characteristics, its typical cross-sectional structure is a huge concave shape, with dock walls on both sides and open front and rear ends.

[0003] When a ship enters or exits a floating dock, to prevent the floating inertia of the ship from colliding with the dock wall, most floating docks are equipped with a ship entering and exiting towing system. The towing system generally consists of components such as a towing cart, a cart track, a wire rope, a fixed pulley, and a wire rope winch. Its working principle is that the cart track is arranged longitudinally along the dock wall, connecting the towing cart, the wire rope, and the friction winch in series to form a coherent operating system. The direction of the wire rope is restricted by the fixed pulley. When the friction winch rotates, it drives the wire rope to drag the towing cart to move along the cart track. By reversing the winch, the walking direction of the cart can be changed. A towing hook is provided on the cart, and the two sides of the ship entering and exiting the dock are fixed to the towing cart through mooring cables or wire ropes. The friction winch drives the towing cart to move along the track, driving the ship to enter and exit the dock orderly and smoothly.

[0004] There are two common methods for installing wire ropes: when the diameter of the wire rope is small, personnel can directly lead the wire rope to the winch and manually wind it for more than 3 - 5 turns, then drive the winch, and the wire rope is threaded and installed along the set path through the operation of the winch; when the diameter of the wire rope is large, generally professional installation tools are used and installed through a large installation winch. The towing wire rope of the towing system on a floating dock generally has a relatively thick diameter and a long length to meet the towing force requirements. It is impossible to install the wire rope only by manpower and requires a large installation winch. At the same time, it is necessary to deploy a professional external cooperation team for installation, resulting in a high installation cost. Moreover, due to the limitation of the ship type layout and the configuration of site equipment and facilities, the large installation winch cannot be arranged on the floating dock deck.

[0060] When the floating dock is performing ship in-and-out operations, first, the two sides of the ship entering and leaving the dock are fixed to the hooks of the towing carts by mooring ropes or steel wire ropes. By starting the friction winch 7 to rotate, the steel wire rope is driven to drag the towing cart 8 to walk along the trolley track. Then, by adjusting the rotation direction of the friction winch 7, the walking direction of the towing cart 8 is changed. Furthermore, the friction winch 7 drives the towing cart 8 to drive the ship to enter and leave the floating dock orderly and smoothly, effectively avoiding the collision between the ship and the dock wall due to floating inertia. The present invention arranges and completes the installation operation of the towing rope with typical ship equipment, has a simple structure, is safe and reliable, and has strong practicability.

Assembly of wire rope bracket The wire rope bracket is set in the area between the friction winch and the fixed pulley on the top of the first deck and the fixed pulley on the top of the second deck, and the bottom of the supporting frame is welded and fixed to the dock wall deck, and then the cross bar is passed through the bundle core of the wire rope and placed as a whole between the two supporting frames, and finally the ends of the cross bar are locked and fixed by sealing plates; S2. Welding of the nut at the end of the wire rope and fixing of the guide rope First, a connecting nut is welded at each end of the wire rope to connect and fix it with the guide rope, and a magnetic particle inspection is performed after the nut is welded to ensure the firmness of the welding; then the first end of the guide rope is passed through the nut at the first end of the wire rope and fixed by a wire rope clamp, and the rest of the guide rope is wound onto the drum of the friction winch; S3. Pulling of bow wire rope First, pull the second end of the guide rope out from the friction winch drum and pass it through the fixed pulley on the top of the second deck, the fixed pulley on the bottom of the second deck, the pulley on the bottom of the third deck, the pulley on the top of the third deck, the bow fairlead, the bow steering horn until it reaches the bow mooring winch. Reel in the first end of the guide rope through the auxiliary drum of the bow mooring winch until the first end of the wire rope is pulled to the pulley on the top of the third deck. Temporarily fix the first end of the wire rope with a wire rope clamp to prevent the wire rope from falling back due to gravity. Then pull the second end of the guide rope out from the auxiliary drum of the bow mooring winch and wind it along the dock wall deck. The surface is pulled toward the stern of the ship, and successively passes through the stern fairlead, the stern steering horn to the stern mooring winch, and the temporary fixation of the first end of the wire rope is removed; then the auxiliary drum of the stern mooring winch is opened to reel in the second end of the lead rope, until the first end of the wire rope is pulled to the bow of the traction trolley, the first end of the wire rope is fixed to the bow side eye plate of the traction trolley through the wire rope clamp, and the fixation of the first end of the lead rope and the first end of the wire rope is removed; finally, the stern mooring winch is started to retract all the lead ropes to the auxiliary drum of the stern mooring winch for standby use, and the traction installation of the bow wire rope is completed; S4. Pulling of the stern wire rope First, place all the remaining wire ropes of the wire rope bundle core on the surface of the dock wall deck and remove the wire rope bracket. Then, pull out the first end of the guide rope from the auxiliary drum of the stern mooring winch and pass it along the surface of the dock wall deck successively through the stern turning bitt, the stern fairlead, the stern side eye plate of the towing cart, the top pulley of the fourth deck, the bottom pulley of the fourth deck, the bottom fixed pulley of the first deck, the top fixed pulley of the first deck until the side of the friction winch close to the bow of the ship. Next, fix the first end of the guide rope and the second end of the wire rope with a nut. Then, rotate the stern mooring winch in the reverse direction to wind up the guide rope, and drive the second end of the wire rope to move reversely along the current path by the first end of the guide rope until the second end of the wire rope is led to the stern side eye plate of the towing cart and temporarily fixed. Then, continue to rotate the stern mooring winch until the wire rope is in a tightened state. Remove the temporary fixation and fix the second end of the wire rope and the stern side eye plate of the towing cart with a wire rope clip. Finally, remove the fixation between the guide rope and the wire rope to complete the traction installation of the stern wire rope. Repeat steps S1 - S4 to complete the installation of the wire rope on the other side of the dock wall.
