  By the way, the transport vehicle 2 according to the present embodiment arranges the driving carts 4A and 4D at the head and the tail of the traveling direction, respectively, and the transport carts 5A and 5B and the driving cart between the driving carts 4A and 4D at both front and rear ends. 4B and 4C are mixed and connected. The transport vehicle 2 first determines the number of drive carts 4 that can be boarded by one person and the number of transport carts 5 that can be boarded by two persons according to the personnel required for the work. The drive cart 4 can pull a plurality of transport carts 5, but the travel distance (travel time) becomes shorter as the number of towed vehicles increases. For this reason, it is preferable that one driving carriage 4 pulls one transportation carriage 5 in order to reduce the weight of each carriage 4 and 5. For example, in order to transport eight workers to a work place several kilometers away, driving carts 4A, 4D are arranged at the front and rear ends, and two transport carts 5A, 5B and two driving carts 4B, It is preferable to use a 4C vehicle organization.

  As shown in FIG. 7, when the transport vehicle 2 has driving carts 4A and 4D arranged at the head and the tail in the traveling direction, and the transport carts 5A and 5B and the driving carts 4B and 4C are connected together, as shown in FIG. In addition, the carts 4 and 5 are connected by a connector 50 with a relay cable 51. Connectors 50 arranged on both sides in the front-rear direction are connected to the transport cart 5 by a transport cart connection cable 52. The drive control device 15 of the drive carriage 5 and the operation panel 16 are connected by an operation system-control power cable 54 via a connector 53. For this reason, when the driving cart 4A is arranged at the head in the traveling direction and the operation system of the operation panel 16 of the other driving carts 4B to 4D is switched, the driving cart 4A is connected by the operating panel 16 of the leading driving cart 4A. Drive control of all the drive carts 4B to 4D is performed in synchronization. On the other hand, when the traveling direction of the transport vehicle 2 is changed to the reverse direction as shown in FIG. 6, the last driving cart 4D is the head. For this reason, by switching the operation system of the operation panel 16 of the leading drive truck 4D, the drive control of all the drive trucks 4A to 4C connected by the operation panel 16 of the drive truck 4D is performed in synchronization, Of the other connected drive carts 4A to 4C, the operation system of the operation panel 16 of the last drive cart 4 is switched and left to the command signal from the outside.

  Next, operation | movement of the transport vehicle of this invention is demonstrated based on the effect | action of the transport vehicle 2 which concerns on the said Example. In the transport vehicle 2 according to the above-described embodiment, for example, when eight persons are transported according to the personnel required for the work, driving carts 4A and 4D are arranged at the front and rear ends, and two transport vehicles are interposed therebetween. It can be set as the vehicle organization which connects cart 5A, 5B and two drive carts 4B, 4C together. In the transport vehicle 2 organized in this manner, first, the operation panel 16 of the driving cart 4A at the head in the traveling direction is connected to the driving control device 15 of the cart 4A, and the operation control switch is used to switch to the command control mode. The drive control device 15 is operated by the operation panel 16 of the host vehicle 4A, and a drive control command signal is sent to the outside. Next, the operation panel 16 of all the other connected driving carts 4B to 4D is switched to the external command subordinate mode in which the command signal is given from the outside. In this way, an operator who has boarded the driving cart 4A at the head in the traveling direction operates the operation panel 16 to travel the transport vehicle 2 to which the carts 4 and 5 are connected and move to the target work location (outward). Next, when the work is finished and the direction of travel is reversed (return), the lock pins 22 and 122 of the carriages 4 and 5 are pulled out, the seats 21 and 121 are turned, and the directions are changed to the opposite directions and locked again. The seats 21, 121 are locked to the central support frames 20B, 120B, 120B by the pins 22, 122. At this time, the last driving cart 4D becomes the leading vehicle. For this reason, the operation system of the operation panel 16 of the head driving cart 4D is switched to the command control mode, and the operation system of the operation panel 16 of the last driving cart 4A among the other connected driving vehicles 4A to 4C is changed. Switch to external command dependent mode. The operation panels 16 of the remaining drive carts 4B and 4C remain in the external command dependent mode as in the forward path. Thus, on the return path, an operator who has boarded the driving cart 4D at the head in the traveling direction operates the operation panel 16 to drive and control the other driving carts 4A to 4C, and the transport vehicle 2 to which the carts 4 and 5 are connected. To drive back to the original location. Since the transport cart 5 and the drive cart 4 are mixed and connected between the drive carts 4A and 4D at the front and rear ends in this way, the transport cart 5 and the drive cart 4 are minimally necessary without waste according to the transport personnel. Therefore, the work mobility is improved. Moreover, since the drive control of another drive trolley can be performed by the head drive trolley in the traveling direction, the transport vehicle 2 can be driven by one driver. Further, driving carts 4A and 4D are arranged at both front and rear ends, and the transport cart 5 and the driving cart 4 are mixedly connected between the driving carts 4A and 4D so that the seats 21 and 121 can be turned in the front and rear directions. Therefore, there is no need to lift the carriage from the track and change the direction, and the direction of travel can be changed only by changing the direction of the seats 21 and 121, and the turning work is made efficient. Needless to say, in the case of a return path, it is not necessary to turn all the seats 21 and 121 in the opposite direction to the outward path, and at least only the seat 21 of the drive carriage 4D as the leading vehicle may be turned.

  Since the driving cart 4 has one occupant and both the driving cart 4 and the transport cart 5 form the cart with the frame 8, the weight is reduced. For this reason, if there are at least two workers, the carriages 4 and 5 can be lifted off the track. Moreover, when traveling by the electric motor 11 becomes impossible, the connection can be released and moved on the track by hand. Further, since the electric motor 11 is constituted by a DC motor, an inverter of the lithium ion battery 14 is not necessary.

  In the above embodiment, the seat 21 is provided on one side of the left and right sides of the drive carriage 4 and the electric motor 11 and the battery 14 are provided on the other side. However, the present invention is not limited to this. The seat 21 may be provided above the motor 11 and the battery 14. Moreover, in the said Example, although the seat 21 is provided in one side among the right-and-left both sides of the drive trolley 4 and the seats 121 and 121 are provided in the left-right both sides of the transport trolley 5, it is not restricted to this, The drive carriage 4 may be provided with the seat 21 and the drive systems 11 and 14 before and after the frame body 8, and the transport carriage 5 is provided with the seats 121 and 121 at the front and rear to secure the loading platform. It may be. Further, in the above-described embodiment, the seats 21 and 121 are detachably set on the carts 4 and 5, but for the carts other than the head driving cart 4A (4D), the seats 21 and 121 are removed and the tools and luggage are removed. It goes without saying that you may be allowed to carry.
