DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for winding a cable used for laying an optical cable or the like.

[0002]

2. Description of the Related Art When laying an optical cable or a power line, it is wound around a drum through a wire rope having a diameter of about 4 mm and a length of 50 to 250 m through a buried underground pipe. The starting ends of the optical cables.
Therefore, the worker who entered the manhole steadily pulled the wire string until the wire rope appeared, and when the wire rope appeared, removed the wire string and pulled the wire rope out of the manhole, and it was installed on the ground. 2. Description of the Related Art Winding is performed by a large winding device. Also, after the laying work was completed, the drawn string was manually wound around a drum or the like.

[0003]

By the way, the above-mentioned work of manually winding the long wire string in a narrow manhole is as follows.
It was very annoying and inefficient. In addition, after the laying work is completed, it is necessary to manually rewind the drawn-in cords, and thus it has been desired to improve such manual work.

[0004] Therefore, the present invention can be easily installed in the opening of the buried pipe in the manhole, and automatically winds the wire string in the buried pipe, thereby facilitating the winding operation. In addition, an object of the present invention is to propose a small and easy-to-carry-up winder capable of improving the work efficiency required for this.

[0005]

According to one aspect of the present invention, there is provided a support tool for inserting and fixing a tip portion into an opening of a buried pipe opening in a side wall of a manhole, and a motor. A drive unit provided with a drum which is driven and rotated by the device to wind up a wire string in the buried pipe, and wherein the drive unit is detachably provided at a rear end of the support.

According to another aspect of the present invention, there is provided a support for inserting and fixing a tip end into an opening of a buried pipe opening on a side wall of a manhole, and a driving device driven and rotated by a motor device. A drive unit provided with a drum that winds up a transmission line in a buried pipe. The drive unit is attached to a rear end of the support so as to be swingable within a small horizontal angle range. It is characterized by being provided detachably from the

[0007]

According to the first aspect of the present invention, the support is fixed by inserting the end of the support into the opening of the buried pipe which opens into the side wall of the manhole. Is attached to the rear end of the support, thereby assembling the support and the drive unit. Then, when the motor device is driven after connecting the starting end of the wire string passed through the buried pipe to the drum, the wire string is automatically wound by the rotation of the drum. After the winding of the string is completed, the tip of the support is pulled out from the opening of the buried pipe.

[0008] Further, the winding device of the present invention,
By attaching the drive unit to the rear end of the support, the drive unit is swingably mounted within a small horizontal angle range. However, by winding the drive unit to the left and right with respect to the support when winding the line string, the line string fits in a compact manner so that it overlaps in a twill pattern. It becomes difficult to do.

According to the winding machine of the present invention, since the winding line can be automatically wound without having to pull one by one, the operator is free from troublesome work.
In addition, the work time related to winding is reduced. Furthermore, it has many advantages that it is compact, easy to use, and can be easily installed at the time of use.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a winding device for a wire string, FIG. 2 is a side view of the same, FIG. 3 is a perspective view of a support, and FIG.
FIG. 4 is an explanatory view showing a state in which a winding device of a wire string is installed in a manhole.

[0011] Winding machine 1 for the wire string shown in Figs.
Comprises a support 10 and a drive unit 20. The support member 10 has a front end 11a of a long horizontal rod 11 and a backing plate 12 fixed to the opening o of the buried pipe p, which is notched to allow the wire string a to come and go. Groove 1
The cylindrical body 13 having the upper surface 4 is fixed by welding or the like in the axial direction of the horizontal rod 11. Further, a downward shaft rod 15 is provided at the rear end 11b of the horizontal rod 11, and a stopper 16 for restricting the swing of the drive unit 20 within a small angle range α is provided.

The drive unit 20 is provided with a cage-shaped frame 21 having an open top, and a short tube 23 for loosely fitting the shaft 15 is fixed to the center of a front portion 22 of the frame 21. A motor device 25 having a speed reduction mechanism is attached to one side surface 24 of the frame 21, and a control device 27 for controlling the motor device 25 is provided at a rear portion 26 of the frame 21. One of the rotation shafts 29 of the drum 28 for winding the wire string a is connected to the output shaft 25a of the motor device 25, and the other is fitted to the support arm 30, and the motor device 2
5, the drum 28 is configured to be driven and rotated. 3
Reference numeral 1 denotes a handle protruding from the side surface 24 of the frame 21. Thus, when the winder 1 is used, the short pipe 23 of the drive unit 20 is fitted to the shaft 15 of the support 10 and is prevented from coming off by the pin 17, so that the support 10 and the drive unit 20 are integrated. Assembling shall be performed.

The operation of the winding device of the above construction will be described. As shown in FIG. 4, the support 10 is fixed by inserting the cylindrical body 13 into the opening o of the buried pipe p opening in the side wall w of the manhole m, and then supports the short pipe 23 of the drive unit 20. It is attached to the shaft 15 of the tool 10. Thereby, the support 10 and the drive unit 20 are integrated. Then, buried pipe p
By connecting the starting end of the line string a passed through the drum 28 to the drum 28 and then driving the motor device 25, the line string a
Is automatically wound up by the rotation of the drum 28. When winding the wire string a, the operator grasps the handle 31 and swings the drive unit 20 right and left,
Since the wire string a is compactly accommodated so as to overlap in a twill shape, the collapse of the wire string a is prevented.
