Description

This disclosure relates to a storage device.

Transport vehicles for transporting cargo are known that have a passenger section where crew members board, and a container for carrying cargo that is mounted on a chassis that extends rearward from the bottom of the passenger section, and the container can be separated from the chassis (see, for example, Patent Document 1). Patent Document 1 describes a transport vehicle in which the cargo compartment of the vehicle body is made of a swap body that can be attached and detached to the chassis.

A known example of such a container that can be separated from the chassis is a container (hereinafter referred to as a "swap body container") that has legs (hereinafter referred to as "outriggers") that extend downward from the bottom surface of the container and can stand on its own by erecting the outriggers on the ground. When such a swap body container is separated from the transport vehicle, it stands on the ground by the outriggers, forming a space between the ground and the container main body into which the chassis of the transport vehicle can enter.

JP 2002-200989 A

Below, one embodiment of a storage device according to the present disclosure will be described with reference to the drawings. In the following description, the front-rear direction means the front-rear direction of the transport vehicle 20, and the left-right direction means the left-right direction when the transport vehicle is facing forward. In addition, the left-right direction is also the width direction of the transport vehicle 20, and therefore may also be referred to as the vehicle width direction.

First Embodiment
Hereinafter, a first embodiment of the present disclosure will be described with reference to FIGS. 1 to 10. FIG.
As shown in Figures 1 and 10, the storage device 10 of this embodiment is a device that stores multiple swap body containers 23 (two in this embodiment) mounted on a transport vehicle 20 (e.g., a truck).

First, the transport vehicle 20 will be described.
As shown in Figure 1, the transport vehicle 20 of this embodiment includes a cab 21 in which the crew boards, a chassis 22 extending from the bottom of the cab 21 to the rear of the vehicle, and a swap body container 23 fixed on the chassis 22.

The swap body container 23 is a box-shaped member having a substantially rectangular parallelepiped shape. A space is formed inside the swap body container 23 in which cargo is loaded.
As shown in Fig. 2, a pair of steering tunnels (loading portions) 24 extending along the longitudinal direction (vehicle front-rear direction) are fixed to the underside of the swap body container 23. The pair of steering tunnels 24 are arranged to be spaced apart by a predetermined distance in the left-right direction across the central axis of the swap body container 23 in a plan view. The longitudinal length of the steering tunnels 24 is approximately the same as the longitudinal length of the swap body container 23.

As shown in FIG. 4, each steering tunnel 24 is a member whose cross-sectional shape when cut along a plane perpendicular to the longitudinal direction is approximately C-shaped. In detail, each steering tunnel 24 integrally includes a plate-shaped fixed plate portion 24a whose upper surface is fixed to the lower surface of the swap body container 23, a plate-shaped vertical plate portion 24b that bends at approximately a right angle from the inner end of the fixed plate portion 24a in the vehicle width direction and extends downward, and a horizontal plate portion 24c that bends at approximately a right angle from the lower end of the vertical plate portion 24b and extends outward in the vehicle width direction.

When the swap body container 23 is loaded on the transport vehicle 20, the horizontal plate portion 24c of the steering tunnel 24 is placed on the upper surface of the chassis 22, and supports most of the load of the swap body container 23. The inner surface of the vertical plate portion 24b in the vehicle width direction is in contact with a plurality of rollers (not shown) arranged in a line in the longitudinal direction on the chassis 22. Each roller rotates about a central axis extending in the vertical direction. The rotation of the rollers facilitates the longitudinal movement of the swap body container 23 relative to the chassis 22 when loading the swap body container 23 onto the transport vehicle 20 or when unloading the swap body container 23 from the transport vehicle 20.
In addition, when the swap body container 23 is being raised and lowered by the lifting device 13 described later, and when the swap body container 23 is stored in the space S2, the horizontal plate portion 24c of the steering tunnel 24 is placed on the upper surface of the lifting frame 14 (more specifically, the longitudinal frame 14a) of the lifting device 13 (see Figure 4).

2, a plurality of cross members 25 (three in this embodiment as an example) are provided on the underside of the swap body container 23, extending perpendicular to the steering tunnel 24. The plurality of cross members 25 are arranged in a line at predetermined intervals in the vehicle longitudinal direction. In detail, the cross members 25 are arranged at both ends and the center of the swap body container 23 and the steering tunnel 24 in the vehicle longitudinal direction. Outriggers (legs) 26, which will be described later, are provided on both ends of the cross members 25 in the vehicle width direction. The cross members 25 are supported by the steering tunnel 24.
As shown in FIG. 2 , a plurality of (four in this embodiment, as an example) bottom corner fittings 27 are provided on the bottom surface of the swap body container 23 .

As described above, the outriggers 26 are provided at both ends of each cross member 25. That is, in this embodiment, six outriggers 26 are provided. As shown in FIG. 5 and other figures, the outriggers 26 are rod-shaped members. The outriggers 26 can be changed between a stored position (see FIG. 4) parallel to the steering tunnel 24 and the swap body container 23, and a free-standing position extending vertically downward (see FIG. 5). The change between the stored position and the free-standing position can be performed manually.

Next, the storage device 10 will be described.
As shown in Figure 1, the storage device 10 includes an entry section (first storage section) 11 through which a transport vehicle 20 can enter, a frame section (second storage section) 12 erected on the upper surface of the entry section 11, and a lifting device 13 for raising and lowering a swap body container 23.

The upper surface of the boarding section 11 is mostly flat, and the transport vehicle 20 can run on this flat upper surface. In addition, a recess 11a is formed on the upper surface of the boarding section 11 in which the lifting frame 14 of the lifting device 13 described later is accommodated. The depth of the recess 11a is approximately the same as the vertical length (height) of the lifting frame 14. In other words, when the lifting frame 14 is accommodated in the recess 11a, the upper surface of the boarding section 11 and the upper surface of the lifting frame 14 are approximately flush. This configuration makes it easier for the transport vehicle 20 to run on the upper surface of the boarding section 11 when the lifting frame 14 is accommodated in the recess 11a (i.e., when the transport vehicle 20 carrying the first swap body container 23 enters).

The frame 12 has a number of pillars 12a erected on the upper surface of the boarding area 11, and a number of beams 12b connecting the upper ends of adjacent pillars 12a. As shown in FIG. 3, the pillars 12a are arranged in sets of two at a predetermined interval in the vehicle width direction, and are arranged in multiple sets at a predetermined interval in the vehicle fore-and-aft direction (the longitudinal direction of the swap body container 23). Note that, for illustration purposes, FIG. 1 and other figures only show the pillars 12a arranged at both ends in the vehicle fore-and-aft direction.

3, the beams 12b connect the column sections 12a arranged at the front end to each other, connect the column sections 12a arranged at the rear end to each other, and also connect the column sections 12a arranged in the front-rear direction to each other.
In this embodiment, the space S1 surrounded by the frame portion 12 and the upper surface of the boarding section 11 surrounded by the frame portion 12 are included in the first storage section.

1, the lifting device 13 includes a lifting frame (supporting portion) 14, a hoisting device 15 (e.g., a winch) that serves as a driving source for lifting the lifting frame 14, a chain 16 that is connected to the lifting frame 14 and wound up by the hoisting device 15, and a pulley 17 that changes the extending direction of the chain 16. The hoisting device 15 is provided on the upper surface of the frame portion 12. The hoisting device 15 and the lifting frame 14 are connected by four chains 16. The chains 16 are fixed to each end of two short-side frames 14b of the lifting frame 14, which will be described later.
In this embodiment, the space S2 above the lift frame 14 fixed to the frame portion 12 is included in the second storage portion.

As shown in FIG. 3, the lifting frame 14 has a plurality of longitudinal frames 14a (two in this embodiment) extending along the longitudinal direction of the swap body container 23, a plurality of transverse frames 14b (two in this embodiment) extending along the transverse direction of the swap body container 23, and a connecting frame 14c connecting the ends of the two longitudinal frames 14a. The lifting frame 14 is accommodated in a recess 11a (see FIG. 1) formed on the upper surface of the boarding section 11.

The two longitudinal frames 14a are arranged to be spaced apart from each other by a predetermined distance in the short direction (left-right direction). The longitudinal length of the longitudinal frame 14a is longer than the longitudinal length of the swap body container 23. As shown in FIG. 3 and FIG. 5, the longitudinal regulating portion (regulating portion) 18 is provided on the upper surface of both ends of the longitudinal frame 14a. The longitudinal regulating portion 18 is provided so as to protrude upward from the upper surface of the longitudinal frame 14a. Each longitudinal regulating portion 18 abuts against or is close to the longitudinal end surface of the swap body container 23. The longitudinal regulating portion 18 abuts against the swap body container 23 to regulate the longitudinal movement of the swap body container 23. The surface on the swap body container 23 side is inclined so as to move away from the swap body container 23 as it moves upward. By configuring in this manner, it is possible to absorb dimensional errors of the longitudinal regulating portion 18 and the swap body container 23.
When the swap body container 23 is lifted by the lifting device 13 (described later) and when the swap body container 23 is stored in the space S2, the steering tunnel 24 is placed on the upper surface of each longitudinal frame 14a. That is, the longitudinal frames 14a support the steering tunnel 24 from below.

The two short-side frames 14b are arranged at a predetermined distance apart in the longitudinal direction. The two short-side frames 14b intersect with the longitudinal frame 14a. The short-side length of the short-side frame 14b is longer than the short-side length of the swap body container 23. As shown in FIG. 3 and FIG. 4, a plurality of short-side regulating portions (regulating portions) 19 are provided on the upper surface of the short-side frame 14b at approximately the center in the short-side direction. The short-side regulating portions 19 are provided so as to protrude upward from the upper surface of the short-side frame 14b. Each short-side regulating portion 19 is provided between a pair of steering tunnels 24. The short-side regulating portion 19 abuts or is close to the surface of the vertical plate portion 24b on the center side in the vehicle width direction. The short-side regulating portion 19 abuts against the steering tunnel 24 to regulate the movement of the swap body container 23 in the short-side direction. As shown in FIG. 4, the short-side direction restricting portion 19 is inclined so that the surface facing the steering tunnel 24 is farther away from the steering tunnel 24 as it moves upward. By configuring it in this way, it is possible to absorb dimensional errors in the short-side direction restricting portion 19 and the steering tunnel 24.

A chain 16 is connected to each end of each short-side frame 14b. The lifting frame 14 can be lifted by winding up the chain 16 with the hoisting device 15.

The lifting frame 14 is positioned so as not to overlap with the outriggers 26 provided on the swap body container 23 in a plan view.

Next, a method for storing a swap body container 23 in the storage device 10 according to this embodiment will be described with reference to Figures 1 and 6 to 10. In the following description, the first swap body container 23 will be referred to as swap body container 23A, and the second swap body container 23 will be referred to as swap body container 23B.

First, as shown in FIG. 1, a transport vehicle 20 carrying a swap body container 23A is driven into the entrance section 11. Then, the outriggers 26 provided on the swap body container 23A are manually changed from a stored position to a freestanding position. Then, the outriggers 26 allow the swap body container 23A to stand upright on the top surface of the entrance section 11. At this time, a chain 16 is connected to the end of the short-side frame 14b.

Next, as shown in FIG. 6, the transport vehicle 20 from which the swap body container 23A has been removed is moved forward and exits the boarding area 11, leaving the freestanding swap body container 23A in the boarding area 11 (space S1).

Next, as shown in Fig. 7, the swap body container 23A is lifted by the lifting device 13. At this time, as shown in Fig. 4, the horizontal plate portion 24c of the steering tunnel 24 is lifted while being placed on the upper surface of the longitudinal frame 14a of the lifting frame 14. In addition, the outriggers 26 are lifted while remaining in a self-supporting position.
When the lifting frame 14 is lifted to a height approximately equal to the height of the beam portion 12b, the hoisting device 15 is stopped and the lifting frame 14 and the frame portion 12 are fixed together. In this manner, the swap body container 23A is moved from the space S1 to the space S2. The swap body container 23A moved to the space S2 is stored in the space S2.

When the swap body container 23A has been moved to space S2, and no swap body container 23 is stored in space S1, the transport vehicle 20 carrying the swap body container 23B is then driven into the entrance section 11, as shown in Figures 8 and 9. Then, the outriggers 26 provided on the swap body container 23B are manually changed from a stored position to a free-standing position. Then, the outriggers 26 allow the swap body container 23B to stand upright.

10, the transport vehicle 20 from which the swap body container 23B has been removed is moved forward and exits the drive-in section 11, leaving the freestanding swap body container 23B in the drive-in section 11 (space S1). As a result, the swap body container 23B is stored in the space S1.
In this way, the swap body container 23 can be stored in both the space S1 and the space S2 which are arranged vertically.

According to this embodiment, the following advantageous effects are obtained.
In this embodiment, since the swap body containers 23 can be stored in both the spaces S1 and S2 arranged vertically, the area required to store the swap body containers 23 can be reduced compared to the case where the swap body containers 23 are arranged horizontally. That is, the space required to store the swap body containers 23 can be reduced in the horizontal direction. Therefore, when storing in the same storage space, the number of swap body containers 23 that can be stored can be increased compared to the case where the swap body containers 23 are arranged horizontally.

The swap body container 23 stored in the space S2 is supported by the frame 12 via the lifting frame 14. That is, the frame 12 and the lifting frame 14 support the swap body container 23 above the space S1, so the load of the swap body container 23 stored in the space S2 does not act on the swap body container 23 stored in the space S1. In general, the swap body container 23 is formed with a relatively low rigidity for the purpose of weight reduction. For this reason, it is not possible to load a swap body container 23 directly on top of the swap body container 23. However, even with such a swap body container 23 with a relatively low rigidity, the lifting frame 14 and the frame 12 support the swap body container 23 stored in the space S2, so two swap body containers 23 can be stored vertically.

When the swap body container 23 is loaded on the transport vehicle 20, the steering tunnel 24 is placed on the transport vehicle chassis and supports most of the load of the swap body container 23. For this reason, the steering tunnel 24 has higher rigidity than other parts of the underside of the swap body container 23. In this embodiment, the lifting frame 14 of the lifting device 13 supports the steering tunnel 24 from below, so that the swap body container 23 is supported from below by the highly rigid steering tunnel 24 even when moving from space S1 to space S2. Therefore, when the swap body container 23 is moved by the lifting device 13, the posture of the swap body container 23 can be stabilized. In addition, when the swap body container 23 is moved by the lifting device 13, no load acts on the relatively low rigidity parts, so the swap body container 23 is less likely to be damaged.

In addition, in this embodiment, the lifting frame 14 and the outriggers 26 are positioned so that they do not overlap, so that the outriggers 26 and the lifting frame 14 are less likely to interfere with each other when the outriggers 26 are placed in a self-supporting position. This makes it possible to easily place the outriggers 26 in a self-supporting position when lowering the swap body container 23 into the space S1. This reduces the burden on the worker.

In addition, in this embodiment, the lifting device 13 has a longitudinal regulating portion 18 and a transverse regulating portion 19 that regulate the horizontal movement of the swap body container 23. As a result, when the swap body container 23 is raised or lowered, the longitudinal regulating portion 18 and the transverse regulating portion 19 regulate the horizontal movement of the swap body container 23. Therefore, the posture of the swap body container 23 can be stabilized when it is raised or lowered. Also, the posture of the swap body container 23 can be stabilized when it is stored.

Second Embodiment
Next, a storage device 30 according to a second embodiment of the present disclosure will be described.
The storage device 30 according to this embodiment differs from the first embodiment in that it includes a pallet 34 instead of the lift frame 14. Other points are substantially similar to those of the first embodiment, so similar configurations are given the same reference numerals and detailed descriptions thereof are omitted.

11, the storage device 30 according to this embodiment includes a rectangular plate-shaped pallet 34. The pallet 34 is accommodated in a recess 11a formed in the upper surface of the boarding section 11.
12 and 13, the pallet 34 is a thin plate-like member, and has curbs 34a on the upper surfaces of both left and right ends. By providing the curbs 34a, the stopping position of the transport vehicle 20 in the vehicle width direction can be regulated.

When the swap body container 23 is being raised and lowered by the lifting device 13 and when the swap body container 23 is stored in the space S2, the outriggers 26 are erected on the upper surface of the pallet 34 (see FIG. 12, etc.). In other words, the pallet 34 supports the outriggers 26 from below.

A chain 16 is connected to the left and right ends of the pallet 34. The hoisting device 15 winds up this chain 16, allowing the pallet 34 to be lifted.

Next, a method for storing the swap body container 23 in the storage device 30 according to this embodiment will be described with reference to Figures 11 and 14 to 18. In the following description, the first swap body container 23 will be referred to as swap body container 23A, and the second swap body container 23 will be referred to as swap body container 23B.

First, as shown in FIG. 11, the transport vehicle 20 carrying the swap body container 23A is driven into the entrance section 11. Then, the outriggers 26 provided on the swap body container 23A are manually changed from a stored position to a free-standing position. Then, the outriggers 26 allow the swap body container 23A to stand upright on the top surface of the pallet 34. At this time, a chain 16 is connected to the pallet 34.

Next, as shown in FIG. 14, the transport vehicle 20 from which the swap body container 23A has been removed is moved forward and exits the boarding area 11, leaving the freestanding swap body container 23A in the boarding area 11 (space S1).

Next, as shown in FIG. 15, the swap body container 23A is lifted by the lifting device 13. At this time, as shown in FIG. 12, the pallet 34 is lifted with the outriggers 26 erected on its upper surface. When the pallet 34 is lifted to a height approximately equal to the height of the beams 12b, the hoisting device 15 is stopped and the pallet 34 and the frame 12 are fixed. In this way, the swap body container 23A is moved from space S1 to space S2 (the space above the pallet 34 fixed to the frame 12). The swap body container 23A moved to space S2 is stored in space S2.

When the swap body container 23A has been moved to space S2, and no swap body container 23 is stored in space S1, the transport vehicle 20 carrying the swap body container 23B is then driven into the boarding area 11, as shown in Figures 16 and 17. Then, the outriggers 26 provided on the swap body container 23B are manually changed from a stored position to a free-standing position. Then, the outriggers 26 allow the swap body container 23B to stand upright.

18, the transport vehicle 20 from which the swap body container 23B has been removed is moved forward and exits the drive-in section 11, leaving the freestanding swap body container 23B in the drive-in section 11 (space S1). As a result, the swap body container 23B is stored in the space S1.
In this way, the swap body container 23 can be stored in both the space S1 and the space S2 which are arranged vertically.

This embodiment also provides the same effects as the first embodiment. In particular, the outriggers 26 are relatively more rigid than other parts, similar to the steering tunnel 24, because they can support the swap body container 23. Therefore, similar to the first embodiment, the posture of the swap body container 23 can be stabilized when the swap body container 23 is moved by the lifting device 13. In addition, when the swap body container 23 is moved by the lifting device 13, no load acts on the relatively less rigid parts, making it difficult to damage the swap body container 23.

The present disclosure is not limited to the disclosure of each of the above embodiments, and can be modified as appropriate without departing from the spirit and scope of the present disclosure.
For example, in the above first embodiment, an example has been described in which the swap body container 23 is hoisted with the lift frame 14 supporting the steering tunnel 24 from below, but the present disclosure is not limited to this. For example, the swap body container 23 may be hoisted with the lift frame 14 supporting the bottom corner fittings 27 from below.
In addition, in each of the above embodiments, a storage device has been described in which two storage sections are arranged vertically to store two swap body containers 23, but the present disclosure is not limited thereto. For example, the storage device may have three or more storage sections arranged vertically to store three or more swap body containers 23.
In addition, in each of the above embodiments, an example has been described in which the lifting frame 14 and the pallet 34 are lifted and lowered via the chain 16, but the present disclosure is not limited to this. For example, a rope may be used instead of the chain 16.

The storage device described in the above-described embodiment can be understood, for example, as follows.
A storage device according to one aspect of the present disclosure is a storage device (10) for storing a container (23) having legs (26) extending downward, the storage device being equipped with a first storage section (11, S1) in which the container is stored and capable of receiving a transport vehicle (20) carrying the container, a second storage section (12, S2) in which the container is stored while being supported above the first storage section, and a lifting device (13) for raising and lowering the container between the first storage section and the second storage section.

In the above configuration, a container can be unloaded from a transport vehicle that has entered the first storage section into the first storage section, and the container unloaded into the first storage section can be moved to the second storage section by the lifting device. The container moved to the second storage section is stored in the second storage section. By moving the container from the first storage section to the second storage section, no container is stored in the first storage section, so a container other than the container stored in the second storage section can be unloaded from a transport vehicle that has newly entered the first storage section and stored in the first storage section. In this way, since containers can be stored in both the first storage section and the second storage section that are arranged vertically, the area required to store containers can be reduced compared to when containers are arranged and stored horizontally. That is, the space for storing containers can be saved in the horizontal direction. Therefore, when containers are stored in the same storage space, the number of containers that can be stored can be increased compared to when containers are arranged and stored horizontally.
In addition, since the second storage section supports the containers above the first storage section, the weight of the container stored in the second storage section does not act on the container stored in the first storage section, so that even containers with relatively low rigidity that cannot be loaded with other containers can be stored in the first and second storage sections.

In addition, in one embodiment of the storage device disclosed herein, the lifting device has a support section (14, 34) that supports from below a load section (24, 26) that is provided on the underside of the container and on which the main load of the container acts.

The load section bears the main load of the container, and therefore has higher rigidity than other parts of the underside of the container. In the above configuration, the lifting device has a support section that supports the load section of the container from below. This means that when moving the container from the first storage section to the second storage section, the highly rigid load section supports the container from below. This makes it possible to stabilize the position of the container when it is being moved by the lifting device. In addition, since the load does not act on the relatively less rigid parts when it is being moved by the lifting device, the container is less likely to be damaged.

In addition, in one aspect of the storage device disclosed herein, the load section has a steering tunnel (14) that is provided on the underside of the container and extends along the longitudinal direction of the container.

When the container is loaded onto the transport vehicle, the steering tunnel is placed on the chassis of the transport vehicle and supports most of the container's load. For this reason, the steering tunnel has higher rigidity than other parts of the underside of the container. In the above configuration, the support part of the lifting device supports the steering tunnel from below, so that the container is supported from below by the highly rigid steering tunnel when moving it from the first storage section to the second storage section. Therefore, the container's posture can be stabilized when it is being moved by the lifting device. In addition, since no load acts on the relatively less rigid parts when it is being moved by the lifting device, the container is less likely to be damaged.

In addition, in a storage device according to one aspect of the present disclosure, the support portion is positioned so as not to overlap with the leg portion provided on the container in a plan view.

For example, when a container is to be made to stand on its legs, an operator may manually change the legs from a stored position (a position in which the legs do not interfere with the travel of the transport vehicle) to a free-standing position (a position in which the legs extend downward from the container). Even in such a case, in the above configuration, the support parts and the legs are arranged so as not to overlap, so that the legs and the support parts are unlikely to interfere with each other when the legs are made to stand on their own. This makes it possible to easily make the legs stand on their own when the container is lowered into the first storage section. This reduces the burden on the operator.
For example, when the transport vehicle is parked at a predetermined parking position in the first storage section, the support portion may be positioned so as not to overlap with the leg portion in a plan view.

In addition, in one embodiment of the storage device disclosed herein, the lifting device has a regulating section (18, 19) that regulates the horizontal movement of the container.

In the above configuration, the lifting device has a regulating section that regulates the horizontal movement of the container. As a result, when the container is lifted or lowered, the regulating section regulates the horizontal movement of the container. This makes it possible to stabilize the position of the container when it is lifted or lowered. In addition, the position of the container can also be stabilized when it is stored.
