Description

The present invention relates to a rope guide device used in, for example, a tugboat.

When towing other ships with tugboats, etc., a large diameter rope is used, but this rope is usually wound around a winch, pulled out through a guide hole of a rope guide device arranged in front of it, and It was stored. As a preparatory work before the towing work, one end of the rope that was gradually drawn out from the winch had to be passed to the towing ship and fixed.

However, since the distance between the winch and the rope guide device is large, the rope fed out from the winch hangs down between the winch and the rope guide device. Conventionally, the hanging rope has been pulled out manually from the bow side of the rope guide device. Usually, since the diameter of the rope is as large as about 60 to 100 mm, there is a problem that the work is very hard work. Therefore, a rope guide device as described in Patent Document 1 has been proposed and put into practical use.

As shown in FIG. 7A, the rope guide device 80 is formed at the center of the pedestal 83, and a pedestal 83 provided with front and rear mounting plates for connecting the supporting columns 81 and 82 and the supporting columns 81 and 82 as a pair. The insertion hole 84, the pair of drive rollers 85, 86 provided so as to protrude into the insertion hole 84, the tilting drive means 87 of the drive rollers 85, 86, and the inlet and outlet sides of the insertion hole 84. And rope-shaped rope guides 88 and 89. Then, as shown in FIG. 7B, the tilt drive means 87 rotates support members 85a and 86a that respectively support drive rollers 85 and 86 driven by a hydraulic motor to a gantry 83 via pins 85b and 86b. A structure that is freely fixed, and the tips of the arms 91 and 92 fixed at angles to the support members 85a and 86a are simultaneously tilted by a hydraulic cylinder 95 via a rod end fitting (connecting fitting) 93 and a pin 94. It was. In addition, 96a is an external connection port of a hydraulic motor and hydraulic cylinder piping.

Utility Model Registration No. 2553700

However, since the arms 91 and 92 are rotated via the pins 85b and 86b, and the rod end fitting 93 is linearly moved by the hydraulic cylinder 95, the pin holes 96 and 97 provided at the front portions of the arms 91 and 92 are not provided. Therefore, there is a problem that the drive rollers 85 and 86 are held with backlash in the left-right direction.
Further, in the second embodiment of Patent Document 1, since the left and right drive rollers are separately driven by the hydraulic cylinders, the problem of backlash is solved, but it is necessary to synchronize the two hydraulic cylinders. Furthermore, there is a problem that the hydraulic cylinder protrudes outward from the column.
