A proximity sensor 10 is provided as a pantograph lift detector for detecting the.

A storage battery 11 and a storage battery 1 are provided in the vehicle body 2.
A charging device 12 for charging 1 is mounted, a power supply circuit 13 from the pantograph 8 is connected to the charging device 12, and a power supply circuit 14 is connected to the storage battery 11. An overhead wire voltage detection device 15 is connected to the power supply circuit 13 via a power supply circuit 16, and the electric motor 5 is connected to the power supply circuit 14 via a motor control device 17 via a power supply circuit 18. ing. Charger 12
Receives electric power from the overhead wire 7 by the pantograph 8 to drive the electric motor 5 and charges the storage battery 11.

A control device 19 is mounted in the vehicle body 2. The control device 19 is a signal transmission circuit 20 with the brake 6, a signal transmission circuit 21 with the proximity sensor 10, and a signal transmission circuit 22 with the storage battery 11.
A signal transmission circuit 23 is connected to the overhead line voltage detection device 15, and a signal transmission circuit 24 is connected to the motor control device 17. The overhead line voltage detection device 15 and the storage battery 11 are connected by a signal transmission circuit 25.

The electric circuit 26 of the control unit 19 has lines 26a, 26b, 26c and 26d as shown in FIG.
Have. When the coil A on the line 26a is excited, the contacts A1 and A2 are brought into conduction, and the contact A3 is released. When the coil B on the line 26b is excited, the contact B1
However, when the coil C of the line 26c is excited, the contact C1 becomes conductive. When the coil D on the line 26d is excited, the contact D1 is released from conduction, and the contact D2 is activated.

The line 26a connects the coil A, the contact B1 and the starting switch SW1 in series, and the contact A1 is connected in parallel with the starting switch SW1. Line 26b is
The coil B, the contact C1, and the contact D1 are connected in series, and the contact D
2 is connected in parallel to the series connection of the contacts C1 and D1. The line 26c connects in series the coil C and the contact E1 of the voltage detection sensor E which is conducted with a voltage.
The line 26d connects in series the coil D and the contact F1 of the pantograph position detection sensor F which is conducted at the pantograph folding position. In addition, the traveling circuit 27 has a contact A2.
Is energized, the circuit 28 for braking is
When the contact A3 is conducting, the brake 6 is operated to perform braking.

Therefore, as shown in the flow chart of FIG. 4, when the pantograph 8 is descending, the contact F1 of the panto position detecting sensor F is made conductive, and the parallel connected contact D2 of the line 26b is made conductive. As a result, the coil B is also excited, so the starting switch SW1
When is pressed, the electric motor 5 can be started. Even if the pantograph 8 is not lowered, the voltage detection sensor E
Detects the overhead line voltage, the contact E1 is made conductive, and the coil B is also excited by the connection between the contacts C1 and D1 connected in series on the line 26b. Therefore, when the start switch SW1 is pressed, the motor 5 can be activated. When the pantograph 8 is not lowered and the voltage detection sensor E does not detect the overhead wire voltage, the contact E1 and the contact F1 are not conducted, so that the starting circuit is turned off and the starting switch SW1 is pressed. Cannot start the electric motor 5.

In addition, in the electrified section, if the on-premise vehicle mobile unit 1 raises the pantograph 8 to collect electricity from the overhead line 7, and a signal with voltage is sent from the overhead line voltage detection device 15 to the voltage detection sensor E, Although the contact F1 of the panto position detecting sensor F is released, the contact E1 of the voltage detecting sensor E is conductive, so if the start switch SW1 is pressed and the coil A is excited, the running circuit 2
7, the electric power is supplied from the overhead wire 7 and the storage battery 11, the electric motor 5 can be driven, and the on-site vehicle mobile device 1 can travel.

In the non-electrified section where the overhead line 7 is not present, a signal indicating no voltage is sent from the overhead line voltage detection device 15 to the voltage detection sensor E to disconnect the contact E1 but the pantograph 8 is lowered. Since the contact F1 of the pantograph position detection sensor F is conducted, the starting switch S
If the coil A is excited by pressing W1, the running circuit 2
7, the electric power is supplied from the storage battery 11, the electric motor 5 can be driven, and the indoor vehicle moving device 1 can run.

However, when the on-premise vehicle mobile unit 1 enters the non-electrified section from the electrified section, if the pantograph 8 is not lowered, the overhead wire voltage detection device 15 sends a signal of no voltage to the voltage detection sensor E. , The conduction of the contact E1 is released, and the conduction of the contact F1 of the pantograph position detection sensor F remains released.
7 is released, the drive of the electric motor 5 is stopped, the contact A3 of the brake circuit 28 is made conductive, the brake 6 is operated, and a braking action is performed, and the on-site vehicle moving device 1 is stopped.

In this case, the pantograph 8 is lowered to bring the contact F1 of the panto position detecting sensor F into conduction,
If the start switch SW1 is pressed, the contact A1 becomes conductive,
The traveling circuit 27 is energized, the electric power is supplied from the storage battery 11, the electric motor 5 can be driven, and the indoor vehicle moving device 1 can travel.

Therefore, when the non-electrified section is entered, the vehicle cannot run unless the pantograph 8 is lowered, so that the pantograph 8 is not hit and broken by a building or the like, and the pantograph 8 can be protected.
