However, the above-mentioned conventional winding method requires a flat place such as a vacant lot or a road where the belt can be linearly stretched. It will interfere with the vehicle and will require a person to monitor it for safety. Further, when the belt is wound up, it is difficult to confirm safety while the vehicle is retreating, and the driver of the vehicle becomes a blind spot for the worker, so that it is difficult to transmit the communication and the signal. Furthermore, since the start of winding is done manually, it is hard work, and it takes a long time to wind, the winding condition is poor, and it is difficult to handle after winding. There is a problem such as not being able to perform.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is possible to wind mechanically from the beginning of winding to the end of winding in a short time and safely without retracting the vehicle. An object of the present invention is to provide a belt winding device that can perform winding.

[0005]

In order to achieve the above-mentioned object, a belt winding device of the present invention comprises a winding shaft and a boom for detachably and rotatably holding both ends of the winding shaft.
