[Technical field to which the invention belongs]

 1 Tow a messenger rope for mooring ropes around φ90 of a large vessel 2 Tow a rope for marine replenishment between vessels 3

[0002]

[Prior art]

 (1) Tow a mooring line of around φ90 of a large vessel is towed by a fixedly arranged take-up winch or by truck. A slip winch without a puller function is used to pull the marine supply rope between the two vessels, and one puller worker is assigned to the rope. (3) The messenger rope or wire is pulled by a take-up winch when laying electric power, telecommunications and various plant wires, or a winch without a puller function is used and one puller worker is assigned. (4) The drum surface is provided with irregularities (damaging the rope) to prevent slippage. (5) In order to prevent entanglement, dead ends (high cost) are provided on both sides of the drum.

[0003]

[Problems to be solved by the invention]

 The slip winch was prone to slipping and turbulent winding despite the respective measures, and had to be equipped with a puller operator, and could only be used safely at a low speed of about 10 m / min. In other words, there was a danger that the puller would be suddenly pulled to the winch side when a slip occurred, or that the rope would be pulled in the opposite direction if a turbulent wind occurred. The winch with puller function of the present invention has the same diameter as the width of the drum, without special R-sections at both ends as seen in the conventional slip winch winch in order to facilitate processing. Also, no irregularities are provided on the surface of the steel drum, so that no slip or turbulent winding occurs even at high speeds of 30 m / min or more, which has been impossible so far. A safe device that does not cause personal injury.

[0004]

[Means for Solving the Problems]

 A pull rubber roller composed of a driving roller and a pressing roller is devised and arranged immediately behind the slip winch as described in claim 1. As described in claim 2, it has been devised to coat the surface of the drum with high hardness and abrasion-resistant rubber evenly by several mm in order to suppress the slip, and a great effect has been confirmed. In order to prevent turbulence even when driving at high speed, a rotating round piece was devised as a rope or wire stopper, and the effect was confirmed by placing it near the center of the drum and at the bottom. thing. As a mechanism for vertically shifting the pressing roller shaft as described in claim 4, the rope between the driving drum and the puller rubber roller is prevented from being loosened or pulled too much.

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0005] Fig. 1 shows an embodiment in which a mooring line (hereinafter referred to as a hauser) having an outer diameter of φ90 of a ship is towed. A messenger rope (φ12) attached to a tip of the hauser is towed at a high speed of 20 to 60 m / min. This is an embodiment of an apparatus for towing a φ90 hoser connected to this to a predetermined position. 1. The puller function roller is a horizontally long circular rubber roller. The lower part is a drive roller having an outer diameter of about half the drum diameter, and the upper part is a pressing roller of φ50. The rubber hardness is relatively soft 50 degrees. The drive roller is directly connected to the motor shaft by a flexible coupling. The holding roller is set on the shaft with a needle bearing, and the shaft does not rotate as a fixed shaft, so that it can be opened and closed as the rope is pulled in and out. That is, one end of the shaft is fixed with a screw, and the other end is released or locked with one touch by a key mechanism (hereinafter referred to as a shaft catch). Furthermore, the holding roller shaft can be raised and lowered using helical screws at both ends according to the rope diameter to be pulled. Fine adjustment of the distance between the shaft and the lower drive roller synchronizes the rope speed with the rope speed of the drum so that the rope between the drum and the puller roller is not loosened or pulled too much. 2. The drum shaft is connected to the motor shaft, the sprocket and the chain. Bearings are provided at both ends of the sprocket to make the drum itself cantilevered, so that the rope can be wound around the drum and removed even from the middle. In addition, the drum diameter is not provided with a special R portion, and the whole width is the same diameter to facilitate processing. Anti-slip rubber is evenly coated on the surface of this steel drum. 3. Since the drum diameter is the same as that of the entire width without the R section, turbulent winding occurs when the rope is wound and pulled. As shown in FIGS. 2A and 2B, this occurs when the ropes after the second winding spirally rotate, advance in the direction of the arrow (right), and pass the ropes of the first winding. What prevents this random winding from occurring is the round rotatable end piece shown in FIG. This round rotatable piece is attached about 0.5 mm from the surface of the slip winch drum with the head separated so that the rope does not bite. By attaching the round rotatable piece, the rope cannot go further to the right and no turbulence occurs. 4. Winches with puller function do not need to touch the rope during towing, and only need to provide a rope pool. That is, it is sufficient to provide a platform with a certain height so that the rope coming out of the puller roller can fall naturally. In addition, the swing function is provided so that the winch with pull function always faces in the towing direction. For this purpose, a rotating pipe (female) is attached to the gantry, a threaded holder is attached to the winch frame with a pull function, and a male pipe with a thread that matches the screw is inserted and screwed in so that the device can swing. did. See FIG. 1c

Claims (4)

[Utility model registration claims] 1. A thin rope or wire (φ6 to φ20)
There are vertical winches, slip winches and the like (hereinafter referred to as slip winches) as winches wound around the towing drum two or three times in the middle of the towing. In the present invention, a puller rubber roller comprising a drive roller and a holding roller is disposed immediately behind the slip winch, thereby eliminating the need for a puller operator. 2. A slip winch made of steel is a slip winch, which slips due to rainwater or the like and reduces the traction force, or when the traction force increases, slips even at a motor capacity or less. A winch with a pull function to prevent slippage by coating the rubber surface with high hardness and abrasion resistant rubber evenly with a thickness of several mm to suppress this slip. 3. The turbulent winding occurs when the rope wound on the slip winch drum spirally moves rightward (leftward in the winding direction) during towing, and the second and subsequent ropes pass the first rope. I do. The present invention has devised a rotating round piece for preventing this turbulent winding phenomenon. The rotating round piece is mounted so that its head comes about 0.5 mm away from the surface of the slip winch drum so that the rope is not pinched during towing. A winch with a pull function that allows the rope to move easily when the rope touches the round piece and turns. The power can be selected from electric, hydraulic, and air depending on the use environment of the user. However, regardless of the power, the pulling speed of the puller rubber roller and the drive drum are substantially synchronized (ideally, the puller rubber roller is slightly moved). Delay). Furthermore, in case the used rope or wire diameter is different due to the user's convenience, the mechanism that the holding roller shaft can be moved up and down linearly eliminates excessive slack and excessive pulling of the rope between the driving drum and the puller rubber roller.
