The guide grooves 26a, 26b are provided with angled projections 27 at their tip openings to prevent the free wheel 25 from easily falling off due to vibration or the like.

In order to securely lock the load supporting hand truck 24 at a predetermined position on the shelf unit 12, a pair of left and right freely engageable and disengageable engagement pins 28 projecting from both left and right sides of the load supporting hand truck 24. The locking lever 29 can be provided on the vertical plate portion 21 of the shelf unit 12. In this case, the pair of left and right locking levers 29 are interlockingly connected to each other by the support shaft 30, and the stopper pin 31 prevents the downward vibration from the locking posture. A cam surface (32) for automatically engaging the locking lever (29) with the locked pin (28) of the load supporting hand truck (24) entering on the horizontal plate portion (22) can be provided. Of course, the locked pin 28 and the locking lever 29
Can be provided only on one side of the load-carrying hand truck 24.

In addition, on the floor surface of the opening 20 as the loading and unloading workshop, an inclined guide plate 33 for laying a step between the floor surface and the bottom surfaces of the guide grooves 26a, 26b on the shelf 12 side is laid. ing.
Further, on the side of the opening portion 20, any shelf unit of the rotary shelf 5 is provided.
An operation panel 34 for performing an operation for calling 12 to the opening 20.
Is provided.

In the rotating shelf 5 configured as described above, by inputting a unique shelf number for each shelf 12 on the operation panel 34 and pressing the start switch, the shelf 12 having the input shelf number is opened. Department
The motor 15 is automatically controlled so as to be called by 20.
When the shelf conductor 12 having a predetermined shelf number is called in the opening 20, the load-carrying hand truck 24 is loaded from above the floor in the vehicle 1 via the inclined guide plate 33. The free wheel 25 can be manually moved so as to be fitted in the guide grooves 26a, 26b in the horizontal plate portion 22 of the shelf unit 12.

Locked pin of trolley 24
By engaging with 28, the load supporting cart 24 is locked to the shelf unit 12.

At the time of unloading work, the load supporting hand cart 24 may be pulled out from the shelf unit 12 which has been called up to the opening 20 as described above. Of course, when the locking lever 29 is provided, either one of the left and right locking levers 29 is manually lifted to disengage both locking levers 29 from the locked pin 28 of the load supporting hand cart 24. In this state, the load-carrying hand cart 24 may be pulled out from the single shelf 12 onto the floor surface of the vehicle 1 via the inclined guide plate 33. At this time, if a spring that selectively holds the locking lever 29 at the upper limit position and the lower limit position is used together, the load supporting hand cart 24 can be pulled out using both hands.

Vehicle 1 is incorporated as one vehicle in the train, and at each stop, there is a doorway 3a or 4a between the platform and vehicle 1.
The hand truck 24 for supporting the load is transferred by using. When using the carousel 5 that also uses the load supporting hand truck 24 in this manner, each load supporting hand truck 24 can be associated with each station, and loading and unloading work of the load at each station can be efficiently performed.

However, the load-carrying hand truck as in the above embodiment
It may be a carousel that does not use 24 together. In this case, as shown in FIG. 5, a rotary shelf 36 having a storage box type shelf unit 35 capable of directly supporting a load is used. Further, like the rotary shelf 36 shown in FIG. 5, the single shelf 35 may be configured to rotate in a vertically long circulation path that is long in the horizontal direction. Further, no matter what type of carousel is used, the passages 17 connecting both ends in the vehicle 1 may be formed on the left and right sides of the carousel, not on one side of the carousel as in the above embodiment. Alternatively, as shown in FIG. 6, it is possible to install the rotary shelves 5 or 36 in two rows and secure the passage 17 in the middle thereof. It is also possible to provide loading and unloading workshops for the individual shelves of the carousel at both ends in the lengthwise direction of the carousel.

When the horizontally circulating rotary shelf 5 is used, when loading and unloading of the load supporting hand cart 24 for the single shelf 12 called in the opening 20 is completed, the work completion switch is pressed to endless chain 10.11 of the rotary shelf 5. If the control system is configured so that the rack 12 is driven to rotate by a unit amount and stops at the position away from the opening 20 as shown by the phantom line in FIG. When the vehicle 1 suddenly stops in the state where the vehicle 1 is moving toward, the shelving unit 12 that is stopped facing the opening 20 is stowed by the recoil when the vehicle 1 is stopped. Load) can be prevented from calling. Needless to say, a lock mechanism (locking lever 29 in the embodiment) for the load supporting hand truck 24 with respect to the single shelf 12 is provided, and a load popping prevention door is provided on the load supporting hand truck 24 to directly store the load. In the case of a single shelf 35 of a type, by providing a load pop-out prevention door on the single rack 35, it is possible to effectively prevent the load from popping out when the vehicle suddenly stops.

(Operation and effect of device) As described above, according to the railway vehicle with the rotating shelf of the present invention, when loading / unloading a load, the loading / unloading place of the rotating shelf calls a single shelf as a target of the loading / unloading work of the rotating shelf. , The load (in the embodiment, the load supporting hand cart 24 supporting the load) may be loaded and unloaded with the called shelf alone, and since the loading and unloading site is located near the entrance and exit of the vehicle. As a result, the load carrying distance by manual work in a narrow vehicle becomes small, and the labor and time required for the work can be greatly reduced.

Further, it is not necessary to secure a work passage in the load storage area in which the rotary shelves are installed, and it is possible to efficiently use the inside of the vehicle for storing the load and reduce the transport cost of the load. Moreover, since the passage connecting the both ends in the vehicle is secured at the side of the carousel, when this vehicle is used as one vehicle in the train, it does not obstruct the passage of people in the train.
