As shown in FIG. 8A, the vehicle body portion 141 of the unit replacement trolley 140 of the modified example supports the mounting portion 151 at the left and right edges of the upper surface when viewed from the rear, and the mounting portion 151 is in the center of the upper surface. Since there is a gap 140a between it and 151, it does not support the mounting portion 151. Further, the vehicle body portion 141 includes an electric actuator 148 (lock mechanism) that is operated by electric power from the battery 46 to raise and lower the rod 148a. When the rod 148a is raised, the tip of the rod 148a protrudes from the upper surface of the vehicle body portion 141, and when the rod 148a is lowered, the tip of the rod 148a is pulled into the vehicle body portion 141. On the other hand, the mounting portion 151 is provided with a plurality of rollers 158 that rotate by contacting the upper surface of the vehicle body portion 141 on the lower surface facing the vehicle body portion 141, and has a size in which the tip of the rod 148a of the vehicle body portion 141 is fitted. The recess 151a is formed. Therefore, in a state where the rod 148a of the electric actuator 148 is raised and the tip of the rod 148a is fitted in the recess 151a, the horizontal relative movement between the vehicle body portion 141 and the mounting portion 151 is irrelevantly locked. Further, in a state where the rod 148a of the electric actuator 148 is lowered and the tip of the rod 148a is pulled out from the recess 151a, the lock between the vehicle body portion 141 and the mounting portion 151 is released. In a state where the rod 148a of the electric actuator 148 is lowered and the lock is released, the mounting portion 151 is in contact with the vehicle body portion 141 by a plurality of rollers 158, so that the mounting portion 151 can move relative to the vehicle body portion 141. Further, as shown in FIG. 9, the mounting device 120 of the modified example includes a support portion 129 capable of supporting the mounting portion 151. The gap 140a of the unit replacement carriage 140 described above is formed so as to accommodate the support portion 129 (see FIG. 8A).

The bogie control device 47 of the unit replacement bogie 140 controls the electric actuator 148 so that the tip of the rod 148a fits into the recess 151a during traveling. As a result, the vehicle body portion 141 and the mounting portion 151 can be integrally and automatically traveled to set the mounting portion 151 on the mounting device 120 (FIG. 9A). When the unit replacement trolley 140 enters the mounting device 120, the support portion 129 of the mounting device 120 enters the gap 140a of the unit replacement trolley 140. When the unit replacement trolley 140 is set, the trolley control device 47 controls the electric actuator 148 so that the tip of the rod 148a comes out of the recess 151a (FIG. 9B). The mounting device 120 of the modified example transmits information to the management device 80 that the vehicle body unit 141 can be exited when the unit replacement bogie 140 is set, and the management device 80 that receives the information is the bogie. An exit instruction may be transmitted to the control device 47, and the bogie control device 47 that has received the exit instruction may control the electric actuator 148. As a result, the lock between the vehicle body portion 141 and the mounting portion 151 is released, and relative movement becomes possible. Further, when the rod 148a of the electric actuator 148 is lowered and the vehicle body portion 141 is slightly lowered downward, the mounting portion 151 is supported by the support portion 129 of the mounting device 120 instead of being supported by the vehicle body portion 141. Therefore, the unit replacement bogie 140 can leave only the vehicle body portion 141 while leaving the mounting portion 151 (FIG. 9 (c)). The support portion 129 may be provided with a mechanism for engaging with the mounting portion 151 so that the support portion 129 can reliably support the mounting portion 151. Further, in the state of FIG. 9C, when the vehicle body portion 141 enters again and the electric actuator 148 is controlled so that the tip of the rod 148a fits into the recess 151a, the vehicle body portion 141 and the mounting portion 151 are locked again. It becomes immovable relative to each other. Therefore, the vehicle body portion 141 and the mounting portion 151 can be integrally exited.

As described above, in the modified example, it is possible to leave only the vehicle body portion 141 while leaving the mounting portion 151 in the mounting device 120. Therefore, since the vehicle body portion 141 can be shared by a plurality of mounting devices 120, it is possible to efficiently replace various units without preparing the same number of vehicle body portions 141 as the number of mounting devices 120. Become.

In the unit replacement bogie 140 of the modified example, the electric actuator 148 is provided in the vehicle body portion 141, but the present invention is not limited to this, and the electric actuator 148 may be provided in the mounting portion 151. Further, the mechanism of the modified example is not limited to the one that locks and unlocks the vehicle body portion 141 and the mounting portion 151, and the vehicle body portion 141 and the mounting portion 151 are locked while traveling, and the unit replacement trolley 140 is mounted. Any mechanism may be used as long as it is possible to unlock and re-lock the vehicle body portion 141 and the mounting portion 151 when entering the apparatus.
