[0003] The winch can take up and rewind the rope by switching the rotation of the motor forward and backward. Further, this winch is fixed to, for example, a lower part of a utility pole, and after the unwound rope is engaged with a suspension car at the upper part of the utility pole, it is used by being locked by a downward load. The winding is performed at a slow speed, but it is desirable that the previous unwinding be capable of rapidly pulling out the rope by hand. To do this, put the clutch between the motor and the reduction gear,
It is necessary to keep the relationship between them.
However, it is structurally difficult to provide an externally operable clutch in the drum. For this reason, the rewinding is performed at the same slow speed as the winding, and there is a problem that time is wasted without meaning.

A hollow shaft is fixed to one side of a motor housing by a flange. The other side of the motor is equipped with a reduction gear,
The output side is engaged with the drum. The motor is rotatably supported inside the hollow shaft or the drum. Both ends of the drum are supported by a frame, and the frame and the hollow shaft are connected by pins.

When the drum is driven to rotate, the motor housing is prevented from rotating by a pin to the frame. When the motor is rotated, the drum rotates slowly and winds up. If the pin is removed, the drum can be rotated integrally with the motor and the reduction gear with respect to the frame, so that the rope can be guided.
At this time, the driving wire is removed by the connector 12. Of course, even if the pin is not pulled out, if the motor is rotated reversely, the rope can be sent out at a slow speed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. The drum 1 is provided with bearing rings 1a and 1b at the centers of both side flanges. The motor 2 has a hollow shaft 3 fixed to one side by a flange 3a, and a rotation support shaft 4 connected to the starting shaft end on the other side. The motor 2 has a drum bearing ring 1 at the end of the hollow shaft 3 and the end of the rotary support shaft 4.
a, 1b to be rotatably supported. A motor drive electric wire is inserted into the hollow shaft via a connector 12. Since a motor in which an electromagnetic brake device is integrated is commercially available, the motor 2 is used. The frame 5 has a U-shape, is fixed to the structure at the center side, and supports both side bearing rings 1a and 1b of the drum at opposite sides. As the reduction gear 6, a commercially available harmonic drive device is used. It consists of an inner and an outer ring meshing with a number of teeth, the inner ring being slightly resilient and having slightly less teeth than the outer ring.
The inner ring is fixed to the rotation support shaft 4 as the output side 6b, and the outer ring is fixed to the inner surface of the drum. The detent plate 7 is screwed and fixed to the outer end of the hollow shaft 3 at its center hole, and a pin 8 is attached thereto. The pin 8 penetrates through the detent plate and is inserted into a hole formed in a corresponding portion of the frame.

FIG. 2 shows a pin device which is easy to attach and detach, instead of the pin 8. The pin 9 is a cylindrical main body 9a as shown in FIG.
The handle 9b is provided with a projection 9c and a grip 9d at the end. As shown in FIG.
a is pierced, into which the spring 10 and the spring retainer 11 are inserted. The inner wall of the bottomed hole 5a is provided with a guide groove 5b whose opening end is closed in the entry / exit direction, and the outer claw of the spring retainer 11 is inserted so as not to protrude from the bottomed hole 5a. The detent plate 7 is provided with a cylindrical projection 7a at a position corresponding to the bottomed hole 5a, and the projection forms a lid hole 7b. As shown in FIG. 4, the lid is provided with a notch 7c through which the projection 9c of the pin 9 can penetrate, and a groove 7d in which the projection 9c fits by shifting the phase by 90 degrees on the inner surface of the lid. Bottom hole 5
a and the lid hole 7b have the same diameter, the pin body 9a is movable between the two, and the handle 9b passes through the lid.

In FIG. 2, the projection 9c engages with the inner groove 7d of the lid, and the main body 9a presses the spring 10 via the spring retainer 11 to be located over the bottomed hole 5a and the lid-fitted hole 7b. When the grip 9d is pressed and turned 90 degrees, the projection 9c passes through the notch 7c of the lid, the pin comes off, and the main body 9a stops contacting the inner surface of the lid. At this time, the surface of the spring retainer 11 is on the same line as the end face of the frame 5, and the pin 9 is
