As shown in FIG. 6, the rear door opening / closing detector 81 includes a power switch 85 connected to a controller 87 that controls an operating device using electric power supplied by the battery 83. Electrically connected to prevent climbing.

Next, the operation of the body part power supply stopping device 80 according to the present invention will be described. The cable laying car 1 has been described so far. Here, a brief description will be given of the cable laying work arranged between telephone poles. The main work to be performed on the cables installed between telephone poles (overhead wire work) is the construction of new overhead cables or the replacement of old overhead cables already installed between telephone poles with new cables. There are replacement work to replace or installation and removal work of bypass cable Cb used for uninterruptible construction method.

[0021] The uninterrupted construction method means that when an electric wire hung between utility poles is deteriorated and the electric wire is replaced, the electric wire is usually replaced after a power outage. Replace the wire without first. The procedure for the construction is as follows. First, a bypass cable Cb is laid between power poles to be connected in parallel to the energized aging wire, and the bypass cable Cb is also energized. Next, the old wires are disconnected and removed, and new wires are installed instead. When power is supplied to a new electric wire, the bypass cable Cb is disconnected and removed.

When erection / removal work of the bypass cable Cb is performed, a cable laid vehicle 1 as shown in FIGS. 1 to 5 is used. In many cases, the section where Cb needs to be installed to avoid a power outage is a plurality of sections.

Therefore, as shown in FIG. 3, in the cable laid vehicle 1, a revolving device 30 is disposed in the box-shaped mounting portion 12, and a plurality of drums 20 are attached to the revolving device 30. For example, to install the bypass cable Cb, the revolving device 30 is driven to sequentially move the drum 20 to a position that can be held by the drum attaching / detaching rotary device 50, and the drum attaching / detaching rotary device 50 is driven. The bypass cable Cb is extended by rotating the drum 20 in the extending direction.

When an interruption such as a lunch break occurs during the operation of the uninterruptible power method, the worker clears the bypass cable Cb so as not to be tampered with by a pedestrian or the like, and supplies power for driving the revolving device 30 and driving the drum 20. The switch 85 is turned off so that the rear door 14 is closed before leaving the site.

However, if the operator forgets to turn off the power switch 85, a warning is given by a lamp or the like for preventing the user from forgetting to turn off the power, which has conventionally been installed in the operation cabinet 11, but the operator has been warned. If they do not return to the operation cabinet, they may leave the site without noticing. However, when the rear door 14 of the box-shaped mounting part 12 is closed even if the power switch 85 is kept on, the rear door opening / closing detector 81 operates by turning on the power supply stopping device 80 according to the present invention. Since the supply is stopped, it is possible to prevent the battery 83 from rising due to forgetting to turn off the power switch 85.

It should be noted that, as a driving device, a hydraulically driven vehicle that is controlled by a controller 87 that operates with the power of a battery 83 has been considered as a driving device for the cable laid vehicle described above. In addition to this, for example, when the drum attaching / detaching device 50 is electrically driven, the electric power from the battery 83 is supplied while the controller 87 controls the vehicle body power supply stopping device 80 of the present invention as shown in FIG. The configuration may be such that:

Furthermore, although the embodiment of the present invention has been described using a cable-installed vehicle, the present invention is not limited to the cable-installed vehicle. Any device can be used as long as it has an operating device that receives power from the battery 83 and operates.

Further, the mounting position of the rear door open / close detector 81 does not need to be the position shown in FIGS. 4 and 5, but may be any position as long as the open / closed state of the rear door 14 is known. Further, the specific configuration of the rear door open / close detector 81 may be a limit switch, a proximity switch, or the like.

[Effects of the Invention] According to the body part power supply suspension device according to the present invention, when the work is interrupted due to a break or the like, the worker is careful that the battery goes out due to forgetting to turn off the power of the body object. It is possible to provide a body part power supply suspension device that can prevent the occurrence of the vehicle body without inviting the vehicle body. By simply closing the door, the present invention can reliably prevent the battery from running up due to forgetting to turn off the power.

Further, conventionally, a lamp or the like for preventing forgetting to turn off the power is installed in the cabin. However, in the future, even if a part for a door open / close detector is added because the present invention eliminates the need, the cost is low and the maintenance is easy. It is possible to provide a simple power-off forgetting prevention device.
