DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for handling a wheel set of a railway vehicle and a wheel set storing apparatus.

[0002]

2. Description of the Related Art Conventionally, a driven axle without a speed reducer has been conventionally loaded and unloaded using a forklift or the like in a three-dimensional warehouse in which a plurality of track shelves (rail shelves) are arranged and stoppers are arranged at each track end. Was. Usually, a plurality of wheel sets are stored in one track shelf, and loading and unloading are performed sequentially from the near side. The work of packing the wheelset in the back of the track shelf or pulling it toward the front was performed manually.

On the other hand, a drive axle equipped with a speed reducer is usually stored on the floor, and only for long-term storage.
Conventionally, a wooden pallet equivalent to a packing skid, a wooden pallet using a packing skid, or a general-purpose pallet has been stored in a state in which a fall prevention or a supporting board is chewed.

[0004]

By the way, in the inspection and repair of a railway bogie, in order to shorten the time required for the inspection and repair, the number of cases in which the wheel axle is replaced with a previously inspected and repaired wheel axle, like other parts, is increasing. As a result, demands for systematic storage management at inspection and repair yards have increased, but conventional manual management has become unable to respond.

[0005] With the review of handling safety of a heavy axle, there has been an increasing demand from a crane to a forklift and further to an AGV, and it has been desired to have a device capable of directly transferring the axle on a buried rail.

[0006] While a wheel set with a speed reducer having a speed reducer rotatable with respect to the axle can be handled in the same manner as a general wheel set without a speed reducer, the wheel set at the entire inspection and repair shop can be stored and managed, and Since the diameter of the wheel changes greatly depending on the state of wear of the wheel, it is necessary that the wheel can be held safely and easily against the change in the diameter of the wheel.

[0007] In addition, it is desired to use a standard warehouse for which the technology is established from the viewpoint of cost.

In view of the above situation, the present invention makes it possible to collectively manage a normal wheel set stored on a track shelf and a wheel set with a speed reducer mounted on the floor collectively in a three-dimensional automatic warehouse, Pallets and pallet trucks that can be automated,
It is another object of the present invention to provide a wheelset storage warehouse using the pallet and the pallet truck as a loading / unloading device.

[0009]

That is, the pallet of the present invention is characterized in that a track provided on a pallet body is provided with a rolling prevention groove for preventing rolling of a wheel set.

As described above, the use of the drop-in pallet prevents the rolling of the wheel set and ensures that wheel sets having different diameters can be held.

[0011] In addition, by making a drop pallet, it is usually necessary to add the pallet thickness to the work height and secure the storage height, but it is subtracted by the drop height to minimize wasteful space. be able to.

In addition, by using a drop-in pallet, a work can be received and paid out while maintaining a loading / unloading surface such as a buried rail, so that automation can be performed by a simple method.

The use of a pallet makes it possible to use a standard three-dimensional automatic warehouse. In addition to making various kinds of works uniform, various kinds of works can be handled with a simple pallet.

In the pallet body, since the caster support surface for the speed reducer is set flush with the upper surface of the track, the loading and unloading of the wheel set can be performed easily.

The pallet carrier of the present invention has an auxiliary track which fits into the auxiliary track filling groove on the back side of the rolling prevention groove to form a part of the track, and a stopper which can protrude from the upper surface of the track. And a lifter for raising and lowering the pallet according to claim 1, so that a railway wheel set usually handled on a buried rail is directly connected to a pallet on a pallet transport trolley arranged on an extension of the buried rail. Acceptance and easy storage in a standard three-dimensional automated warehouse.

Further, in the wheelset storage warehouse of the present invention, the pallet and the pallet carrier are used as a loading / unloading device.

Therefore, a wheel set with a reduction gear which cannot be handled by the standard three-dimensional automatic warehouse can be handled. In addition, a wheel set with a reduction gear for a diesel car without casters can be handled in the same manner by attaching a caster of a separate specification, so that the entire wheel set at the time of inspection and repair can be systematically managed.

[0018]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 5 is a cross-sectional view of the wheelset storage warehouse. The wheelset storage warehouse 31 has a three-dimensional shelf 32 for storing a pallet (not shown) on which a wheelset is mounted or an empty pallet (not shown).
And a stacker crane 34 for transporting a pallet equipped with a wheel set or an empty pallet between the three-dimensional shelf 32 and a carry-in / out entrance 33 (see FIG. 6).

As shown in FIG. 6, two loading / unloading ports 33 are provided, and the floor 3 adjacent to the wheelset storage warehouse 31 is provided.
