However, in the conventional cable conveying device, the wire drawing roller is arranged on the meandering cable tray and the cable is passed between the two rollers of the wire drawing roller. Alternatively, it is carried by a power carrying device. For this reason, after the cable has been extended to a predetermined position, when the cable is removed from the extension roller and the power transfer device and placed on the cable tray, an operator may follow the cable tray installed at a high place. He climbed on the assembled scaffold, opened the transport device and the wire drawing roller one by one, removed the cables, and placed them on the tray.

Therefore, there is a drawback that it is dangerous and requires a lot of trouble. In addition, the automatic opening / closing method in which the wire drawing roller and the automatic conveying device are automatically opened after the cable is drawn and the cable is dropped into the cable tray has a problem that the cost is too high due to its structure, so that the automatic opening / closing method must be used. Of course, it was difficult to automate the wire drawing work.

The present invention has been made in view of the above circumstances, and when arranging a cable on a cable tray at a high place, the cable can be easily and risk-free and can be automated. It is an object of the present invention to provide a carrier device of the above.

A plurality of propulsion cylinders, and a guide tube that is placed between the propulsion cylinders and that can be cracked in the axial direction due to the weight of the cable. Air is conveyed in the hollow formed by the propulsion cylinder and the guide tube, and after the cable is conveyed on the cable tray, the propulsion cylinder is opened to cable the cable. Characterized in that it placed on a.

[0007]

According to the present invention, when the cable is extended, the propelling cylinder and the guide tube are connected to each other and arranged above the cable tray to form a hollow conveying path for conveying the cable. Next, the compressed air is supplied to the propulsion cylinder, the compressed air is ejected from the air outlet to generate an air flow in the transfer path, and the air flow is conveyed through a cable having an air receiving member attached to the tip thereof. .. That is, the compressed air in the transfer path allows the cable to float in the transfer path and minimize the contact resistance with the inner surface of the transfer path, thereby facilitating the transfer of the cable. Further, since the compressed air is ejected toward the outlet of the propelling cylinder, a force for pushing the air receiving member and the cable toward the outlet is applied, and the cable can be conveyed to the outlet of the conveying path.

After the cable is conveyed, when each propelling cylinder of the cable conveying device is opened and the cable is dropped, the guide tube is split in the axial direction by the weight of the cable.
The entire cable will fall and the cable can be placed in the cable tray. As a result, even when arranging the cables on the cable tray at a high place, it can be performed easily and without danger. Further, the propelling cylinder of the cable carrier of the present invention can be easily opened automatically, and the cable carrier can be automated.
