Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a drum-free wire rope pulling and releasing device and a use method thereof. Background Art

[0002] There are many lifting equipment in the shipbuilding industry that require wire ropes. However, when the equipment arrives, the wire ropes are not included. Instead, the wire ropes are packaged and delivered separately. After the equipment is installed on site, the wire ropes need to be threaded onto the sliding elements of the equipment, a process known as wire rope threading.

[0003] The wire ropes used in large cranes are very long. Manufacturers typically deliver the wire ropes wrapped around drums. During threading, the wire rope is pulled out from one end of the outer coil and threaded onto the equipment. The drum is then rotated to thread the wire ropes sequentially onto the equipment. However, many pieces of equipment use shorter wire ropes. Manufacturers don't use drums when delivering the wire ropes, instead coiling the ropes directly into coils and packaging them for delivery. On-site threading and installation requires placing the wire rope on the deck next to the equipment, pulling one end of the rope out and threading it onto the equipment. The rope is then continuously pulled out and fed onto the equipment's wire rope path.

[0004] The following problems will arise during the above operation of the drum-free wire rope: First, the coiled wire rope is placed on the deck. Because the wire rope is relatively heavy on the deck and will not move, as the wire rope is continuously pulled out, the radius of the wire rope loop will become smaller and smaller, and when it reaches a certain level, the wire rope will be twisted. Once the wire rope is twisted, it will be scrapped and cannot be used. In order to avoid this phenomenon, construction workers need to constantly lift and rotate the wire rope loop, which is very physically and time-consuming; second, because there is no drum to limit the wire rope, it will move due to its own elasticity during the process of pulling it out, and it is very easy to get tangled together to form a knot; in order to avoid the above two problems, on-site construction workers usually unfold the wire rope completely and then perform the rope threading operation. This will cause a third problem. During the unfolding process, the end of the wire rope is easy to swing back and forth, which is very easy to accidentally injure the construction workers and surrounding people, posing a great safety hazard. The unfolded wire rope occupies a large construction space, and a cordon needs to be drawn. The process consumes a lot of man-hours and manpower. Summary of the Invention

[0005] The purpose of the present invention is to provide a drum-free wire rope pulling and releasing device and a method of using the same, so as to avoid entanglement of the coiled drum-free wire rope and reduce construction risks, thereby improving the construction efficiency of the wire rope pulling and releasing and having a wide range of applications.
