The number of units 2 and 3 to be installed can be freely set in accordance with the required number of vehicles to be accommodated, various conditions at the installation location of the mechanical parking device, etc., and can be set in the horizontal and vertical directions. Deployment is also free. The present inventors have already disclosed the details of the mechanical parking device having such a configuration in Japanese Patent Application No. 6-53249. Also, regarding the structure of the parking rack 9, it has already been published on August 1, 1994.
It is introduced in the inventions filed on the 1st.

In the mechanical parking apparatus having the above structure, when a fire occurs, the interior of the parking apparatus is filled with an inert gas to shut off oxygen and extinguish the fire. Therefore, it has a gas cylinder storage chamber (not shown), and has a structure in which pipes are stretched from the gas cylinder storage chamber to each part of the parking device and the gas is sent to a fire place.

[0008]

Conventionally, for a fire in a mechanical warehouse, a fire prevention area has been set for each unit. Therefore, the gas cylinder of the quantity which can fill gas in one unit was prepared. However, considering the recent environmental damage,
Gases used for fire extinguishing are being changed to CO ₂ , alternative halon, and other new alternative substances (for example, product name Inergen Gas). However, in order to sufficiently extinguish a fire with these gases, a larger amount of gas is required than in the conventional case. For this reason, there are many problems such as an increase in cost due to an increase in the number of gas cylinders to be prepared and a new securing of an installation place.

The present invention has been made in view of the above problems, and an object thereof is a unit of a mechanical warehouse (hereinafter, also simply referred to as "warehouse") for loading and unloading a load via a traveling carriage. By dividing the inside into two or more parts with a fireproof shutter, one fireproof area is narrowed to reduce the amount of gas required for extinguishing a fire. Also, during normal times, the division of the warehouse can be done freely to improve the operational efficiency of the warehouse.

[0010]

Means for Solving the Problems According to the present invention for solving the above problems, a plurality of luggage compartments are arranged on both left and right sides of a traveling path on which traveling rails of a traveling carriage are arranged,
In a mechanical warehouse having one or a plurality of units capable of transferring loads between the traveling carriage and the luggage compartment, a fire wall is fixed between the luggage compartments on the left and right sides of the traveling path, which are adjacent to each other in the front and rear. A shutter is provided between the left and right fire walls, and a cut portion is provided on the traveling rail at a portion intersecting with an operation path of the shutter.

In the present invention, in the four corners of the traveling carriage,
It is desirable to arrange a plurality of traveling wheels.

[0012]

In the mechanical warehouse having the above-mentioned structure, as a structure for dividing the inside of the unit into a plurality of units, the left and right cargo compartment portions arranged in a row use fixed type fire walls, and the traveling path of the traveling carriage is movable. This is done by installing the fire prevention shutter between the left and right fire walls. Further, the traveling rail is provided with a cutting portion along the operation path of the shutter in order to secure the operation path of the fireproof shutter.

Further, although the traveling carriage supports the traveling wheels at the four corners by dispersing the loads, there are cases in which a plurality of traveling wheels are provided at one corner and the loads applied to one corner are shared by the traveling wheels.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A mechanical parking apparatus which is an embodiment of the present invention will be described below with reference to the accompanying drawings. In the figure, the same or corresponding parts as those of the conventional example are designated by the same reference numerals, and detailed description thereof will be omitted.

1 to 3 show a unit 2 of a mechanical parking device.
Shows the inside. Parking compartments 8 which are luggage compartments are arranged in tandem on both sides of the traveling path 4. Adjacent to this is the parking room 8,
A fire wall 19 is fixed between the eight. Here, the fire wall 19a on one side and the fire wall 19b on the other side are installed at a distance of one room or more in the front-rear direction. further,
A shutter 20 having a fireproof structure is arranged between the ends of the fire walls 19a and 19b. Therefore, the shutter 20
Are provided obliquely with respect to the installation direction of the traveling rail 7. In addition, the shutter 20 is wound up and stored in a storage device 21 provided obliquely with respect to the traveling rail 7 on the top of the traveling path 4. When the shutter 20 operates, the shutter 20 descends while using the ends of the fire walls 19a and 19b as guides.

On the other hand, the traveling rail 7 intersecting on the descending path of the shutter 20 is cut in a direction parallel to the shutter 20 (that is, obliquely with respect to the installation direction of the rail) to form a gap 22 (FIG. 2). ing. The gap 22 has a distance X in consideration of the thickness of the shutter 20 and a gap required when the shutter is lowered.

Only the traveling wheels 16 and the main frame 17 of the traveling carriage 6 are shown in FIGS. 1, 2 and 4. In order to travel on the traveling rail 7, the traveling carriage 6 is provided with a total of eight traveling wheels 16 as a set of two at four corners of the main frame 17. One set of running wheels 1
6a and 16b are installed to be separated from each other so as to exceed the gap 22. By the way, the main frame 17 is not constructed as a rigid rigid body in order to reduce the weight, but allows the running wheels arranged at the four corners to disperse and support the load while allowing a proper degree of bending. If the traveling wheels 16a approach the section Y when the traveling vehicle 6 passes through the gap 22 of the traveling rails 7, the traveling wheels 16a may be in a non-contact state with the traveling rails 7. However, since the other traveling wheels 16b support the load shared on the traveling rail 7, the traveling carriage 6
As it passes through the rail gap 22
7 is not significantly deformed, and the impact when passing can be suppressed. The wheels driven by a traveling motor (not shown) are both 16a and 16b.

In the mechanical parking apparatus having the above-mentioned structure, the shutter 20 is normally wound around the storage device 21 so as not to become an obstacle when the traveling carriage 6 reciprocates on the traveling path 4. When a fire occurs in the unit 2 and the fire is detected by the fire detecting means, the traveling carriage 6 has the shutter 20.
The shutter 20 is stopped at a predetermined evacuation area avoiding the above, and the shutter 20 is automatically lowered at the discretion of an observer, as shown in FIG.
As shown in, the end portion is grounded to the floor surface of the traveling path 4. After that, the fire is extinguished by filling the inside of the fire-prevention section with the fire-breaking site with a gas for extinguishing fire. It should be noted that the shutter 20 can be always operated by an observer not only in an emergency.

In this way, the running path 4 can be closed, and the unit 2 can be divided into a plurality of sections together with the fire wall 19 fixed between the front and rear parking rooms.

Further, when the traveling carriage 6 passes through the cut portion of the traveling rail 7, any one of a plurality of traveling wheels provided at one corner is located on the traveling rail 7 and receives the shared load. The deformation of the main frame 17 is prevented. Also,
If the angle at which the traveling rail 7 and the shutter 20 intersect is set to a more acute angle, the section Y in which the traveling wheels 16 are not in contact with the traveling rail 7 can be reduced, so that the traveling carriage 6 can be smoothly moved. It is effective for running. Moreover, by reducing the section Y, smooth traveling is possible even when using the conventional traveling bogies in which the traveling wheels 16 arranged at the four corners of the traveling bogie 6 are four in total.

On the other hand, as shown in FIG. 5, the left and right fire walls are arranged at the same position in the front-rear direction, and the traveling rail 7 and the shutter 2 are arranged.
Setting the angle at which 0 and 0 intersect at a right angle simplifies the shape of the cut portion of the rail 7. Moreover, since the width of the shutter 20 can be reduced, the cost of parts and the number of installation steps can be reduced. In addition, in this case, the above-mentioned section Y increases, but due to the effect of the plurality of traveling wheels 16 of the traveling carriage 6 being provided in one corner,
The deformation of the main frame 17 does not occur.

Although the mechanical parking device has been described as an example, the present invention is not limited to this, and is a mechanical type device for relaying a traveling carriage and delivering a load to a luggage compartment for various other purposes. It can be used as a warehouse.
Further, the shutter 20 can be used not only in an emergency such as a fire but also as a partitioning device in a warehouse at all times. For example, when a plurality of shutters 20 are provided in a rental warehouse, the shutter 20 divides the inside of the unit, so that the storage capacity of each customer can be freely changed. As a matter of course, the shutter, which hinders the traveling of the traveling carriage 16 when moving in and out, is stored, and the traveling carriage 16 freely reciprocates on the traveling path 4. By using it in this way, it is possible to further improve the inventory management level of the warehouse and perform efficient warehouse operation.

[0023]

As described above, the present invention has the following effects. In the unit forming the mechanical warehouse, the fire wall is fixed between the front and rear cargo compartments, and the traveling path part where the traveling carriage reciprocates moves one unit by lowering the shutter provided on the ceiling. It can be divided into multiple areas. Therefore, one fire protection section becomes small, and the amount of gas required for extinguishing a fire can be reduced. Further, by constantly using it as a zoning device in the warehouse, it is possible to improve the inventory management level of the warehouse and perform efficient warehouse operation.

When a plurality of traveling wheels is provided at the four corners of the traveling carriage, the load can be shared by the traveling wheels. Therefore, when the traveling carriage passes through the cutting portion provided on the traveling rail, even if one traveling wheel is located in the gap between the traveling rails, the other traveling wheels in the pair support the load on the traveling rail. Therefore, the frame of the traveling carriage can be passed more smoothly without being deformed.
