Embodiment Construction
[0041] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.
[0042] Such as figure 2 As shown, the luffing system of the present invention includes a luffing jib frame 5, a steel wire rope and several luffing drums.
[0043] The rope-drawing method of the hoisting ship luffing wire rope of the present embodiment is as follows: image 3 As shown, in this embodiment, the first luffing reel 1 and the second luffing reel 2 are drawn in sequence.
[0044] Such as image 3 As shown, the rope-drawing operation of the first luffing drum 1 and the second luffing drum 2 includes the following steps:
[0045] Step 101. Lift the luffing jib frame 5 above 52 degrees relative to the horizontal plane and brake firmly, and brake the third luffing reel 3 and the fourth luffing reel 4 of the second side group, including the working brake , safety brake locking, ratchet locking and all related electr...

The invention discloses a rope-drawing method for a luffing steel wire rope of a crane ship, which comprises the following steps: step 1, braking the luffing jib; step 2, releasing the steel wire rope on the first luffing drum, The luffing drum retracts the wire rope accordingly until the wire rope on the first luffing drum is finished; step 3, remove the wire rope pressure head on the first luffing drum, fix the head of the wire rope, and the first luffing drum The width reel rotates toward the loosening direction, so that the wire rope is partially drawn out, and then the wire rope pressure head is fixed, and the drawn wire rope is cut off; step 4, the wire rope on the first luffing drum is packed up. The luffing steel wire rope drawing method of the crane ship of the present invention avoids frequent replacement of the steel wire rope, greatly shortens the maintenance and parking time, saves the cost of replacing the steel wire rope, and saves a large amount of tooling equipment costs.
Description
technical field [0001] The invention relates to a hoisting system of a crane ship, in particular to a rope-drawing method of a luffing steel wire rope for a crane ship. Background technique [0002] The crane ship is a very important lifting device in the shipbuilding industry, and its safe and stable operation is directly related to the smooth progress of the shipbuilding plan. The hoisting and luffing wire rope is one of the most important parts in the crane ship. If there is a problem with the wire rope, the crane ship will not be able to work. Therefore, how to ensure the stable and reliable operation of the wire rope, reduce the number of wire rope replacements, prolong the service life of the wire rope, and shorten the maintenance downtime of the crane ship is a major issue in front of the equipment engineering technicians. [0003] The lifting system of the 2500t crane ship is divided into a luffing system and a hoisting system. Among them, the luffing system has two...
