Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a container that can be loaded and unloaded onto, for example, a cargo handling vehicle while maintaining a horizontal attitude.

<Prior Art> Conventionally, there are the following container handling vehicles (Japanese Patent Application Laid-open No. 57615/1983). This container cargo handling vehicle consists of a cargo handling vehicle and a container, and a hook at the tip of a bendable cargo handling arm provided on the body of the cargo handling vehicle can be used to hook a locking portion at the upper front end of the container. I have to. When loading the container onto the cargo handling vehicle, the hook at the tip of the cargo handling arm hooks the locking portion at the front of the container to pull the container diagonally up onto the vehicle body. Furthermore, when loading or unloading a container, the container is similarly turned diagonally and lowered to the ground using the cargo handling arm.

<Problems to be Solved by the Invention> However, with the containers used in the conventional container handling vehicles, the containers are oriented diagonally when being loaded and unloaded onto the handling vehicles.
There was a problem in that it was not possible to load pianos, furniture, fragile items, etc. into this container, and the things that could be stored in this container were limited to garbage, waste, etc.

Therefore, an object of the present invention is to provide a cargo handling vehicle, a ship, a freight train, etc., while maintaining a horizontal position.
To provide a container that can be loaded and unloaded onto a transport machine such as an airplane, and can also be loaded with pianos, furniture, fragile items, etc.

<Means for Solving the Problems> In order to achieve the above object, the container of the present invention includes a container main body, a support member that is provided at the rear of the container main body so as to be able to rise and fall freely, and supports the container main body on the ground; a connecting member fixed to both sides of the front part of the container body; a movable member provided vertically movably at the front part of the container body and located below the connecting member; comprising a transmission means for transmitting relative movement to the support member to raise and lower the support member, the movable member is held at a constant height with respect to the ground, and the connection member is lifted;
It is characterized by the ability to raise the container body approximately horizontally.

The lower end of the support member is preferably provided with, for example, a roller or a grounding member that is immovably in contact with the ground.

<Operation> Now, assume that a container is loaded from the ground onto a cargo handling vehicle, which is an example of a transport machine.

The container is straightly connected to the cargo handling vehicle via connecting members on both sides of the front part of the container body.

First, the movable member at the front of the container is fixed to the ground, and the connecting members on both sides of the front of the container body are connected to lifting members on the cargo handling vehicle and lifted. When the movable member is lifted, the relative movement of the movable member with respect to the container body is transmitted by the transmission means to the support member at the rear of the container, the support member is caused to protrude downward, and the rear part of the container body is lifted. Therefore, the front and rear parts of the container body are raised horizontally in synchronization with each other. At this time, the container body is connected to the cargo handling vehicle at two points on both sides in the horizontal direction via the connecting members on both sides, and
Since the container is lifted while being supported at at least one point (3 points in total) via a movable member, the container body is prevented from wobbling in the lateral direction, and even if the container is loaded on one side, it can be immediately connected to a cargo handling vehicle. Ru. When the height of the container and the height of the vehicle body are the same, the rear part of the container is supported on the ground by the support member, and the container is placed onto the body of the cargo handling vehicle by, for example, pulling the connecting part forward. advance.
Thereafter, the movable member is moved relative to the container body to raise the support member from the ground. Further, when lowering the container to the ground, the container can be lowered to the ground while maintaining a horizontal attitude by performing the operation opposite to the above-described operation.
During the above operations, the container is supported by the cargo handling vehicle at at least three points, including two points on both sides in the horizontal direction via the connecting members, as described above, and can move back and forth and up and down with good stability without swinging from side to side. .

In addition, when the container is raised to the same height as the vehicle body of the cargo handling vehicle, for example, without pulling the connecting member forward, the container is kept stationary and the cargo handling vehicle is moved backward to load the container onto the vehicle body. You can do it like this.

Further, if the support member is designed to be able to be pulled off the ground by itself, the support member can be pulled off the ground without operating the movable member after the container is mounted on a cargo handling vehicle, for example.

Note that the container of the present invention can be similarly loaded and unloaded not only on cargo handling vehicles but also on ships, freight trains, and airplanes.

That is, the front part of the container 1 is lifted up by the connecting member 61, and the rear part is lifted up by the supporting member 3, and their movements are synchronized, so that the container 1 rises horizontally as shown in FIG. 5b. Moreover, since the engagement between the container 1 and the cargo handling vehicle 45 is performed at a total of four locations on both sides and the top and bottom of the container as described above, when the container is connected to the cargo handling vehicle only at the center as shown in FIG. This prevents the container from wobbling as shown by the arrow in FIG. 12, and even when the container 1 is loaded on one side, it can be lifted stably.

When the container 1 reaches the same level as the body of the cargo handling vehicle 45, the operation of the hydraulic cylinder 71 on the cargo handling vehicle side is stopped, the upward movement of the container 1 is stopped, and the hydraulic motor 59 is driven to The device 51 is moved forward, and the container 1 is placed on the guide rollers 99 and moved forward, as shown in FIG. 5c. At this time, the rear part of the container 1 is supported on the ground by the roller 7 at the lower end of the support member 3, and the upper and lower parts of the front part of the container 1 are connected to the cargo handling vehicle side connecting member 61 and the cargo handling vehicle side movable member 91. Therefore, the container side connecting members 11, 11
and is pulled via the container-side movable members 16, 16. After that, the container 1 is transferred to the cargo handling vehicle 45.
The hydraulic cylinder 97 of the cargo handling vehicle 45 is
is contracted, the cargo handling vehicle side movable member 91 is raised, the container side movable members 16, 16 are raised, the support members 3, 3 are lifted up from the ground via the chains 31, 31, 30, 30, and the fifth Make the state as shown in Figure d.

When unloading the container 1 from the cargo handling vehicle 45, the operations may be performed in the order of d, c, b, and a in FIG. 5 in the reverse order of the operations described above.

In this way, this container handling vehicle lifts or lowers the front part of the container 1 using the connecting members 11, 11 while simultaneously supporting the container 1 at four points, two on each side. The container body 2 of the container-side movable members 16, 16

Therefore, the container 1 can be loaded onto and unloaded from the cargo handling vehicle 45 while maintaining a horizontal attitude.

Further, since the support member 3 at the rear of the container can be operated by the movable member 16 at the front of the container, this container cargo handling vehicle simply consists of the cargo handling vehicle side movable member 91, the container side movable member 16,
16 and the cargo handling vehicle side connecting member 61 and the container side connecting members 11, 11, the container 1 can be easily loaded and unloaded while maintaining a horizontal attitude. In addition, the container body 2
The cargo handling vehicle 45 is
Since the container is supported at four points, there are no problems that would occur if the container was supported only at the center, as shown in Figure 12. Even if it is connected immediately, in the case of a single load, there will be no inconvenience such as unstable operation, and stable operation without wobbling can be obtained. Therefore, this container 1 can be loaded and unloaded without any problem even when loaded with pianos, furniture, fragile items, etc.

6 and 7 show modified examples of the container, in which the chains 30 and 31 as the transmission means in FIG. 1 are basically converted into hydraulic piping.
That is, this container has a container body 102
A column-shaped support member 103 is provided on both sides of the rear portion of the vehicle so that it can be raised and lowered by being guided by a guide member 105. A hydraulic cylinder 106 is provided within this support member 103,
This hydraulic cylinder 106 is attached to the guide member 105 via a pin 109, the tip of the hydraulic cylinder 106 is attached to the lower surface of the support member 103, and the roller 107 is attached to the lower end of the support member 103 via a bracket 108. On the other hand, connecting members 11 provided on each side of the container body 102
1 has the same configuration as the connecting member 11 in FIG.
In this embodiment, it is not fixed to the support plate 12 but directly to the outside of the side surface. Further, each movable member 116 has the same structure as the movable member 16 in FIG. This movable member 116 is connected to the tip of the piston rod of a hydraulic cylinder 123, and the lower part, or head side, of this hydraulic cylinder 123 is connected to the upper part, or head side, of the hydraulic cylinder 106 by a pipe 142.
The rod side of the hydraulic cylinder 106 is connected to the rod side of the hydraulic cylinder 123 by a pipe 140. That is, this configuration is diagrammed as shown in FIG. 7. Therefore, the movable member 1
By lowering the hydraulic cylinder 10
The support member 103 is lowered together with the piston rod 6, and conversely, when the movable member 116 is raised from the lowered state, the hydraulic cylinder 106 passes through the pipe 140.
Oil is supplied to the rod side of the hydraulic cylinder 10.
6 piston rod is inserted. That is, the container shown in FIGS. 6 and 7 uses a hydraulic system instead of a chain drive system to move the movable member 116.
This embodiment differs from the embodiment shown in FIG. 1 only in that the action of is transmitted to the support member 103.

FIG. 8 and FIG. 9 show another modification of the container. This container 201 differs from the container 1 shown in FIG. 1 only in that a grounding member 202 is provided at the lower end of the support member in the form of a flat plate and having a corrugated holding portion 202a on the lower surface. Identical components are given the same numbers and explanations will be omitted.

Since the lower end of the support member 3 is connected to the ground by the grounding member 202, this container 201 has a ninth
When the cargo handling vehicle 45 itself is moved backward as shown by the arrow in the figure, the container 201 is loaded onto the cargo handling vehicle. At this time, the column device 51 is in a free state and is pushed by the container 201 to move forward relative to the body of the cargo handling vehicle 45. container 20
1 is completely mounted on the cargo handling vehicle 45, the support member 3 is pulled up and the grounding member 202 is separated from the ground.

In this embodiment, the grounding member 202 at the lower end of the support member 3 is fixed on the ground to allow the cargo handling vehicle 45 to move backward, so if the ground is uneven, the roller 7 shown in FIG. 1 may be used. In comparison, it can be used without any problems.

FIGS. 10 and 11 show still another modification of the container. This container is shown in Figure 5d.
Instead of operating the movable member to pull up the support member, the substantially central portion of the support member can be bent forward. This support member connects the lower support member 302 to the upper support member 301 with support pins 303.
It is connected so that it can be bent at the lock pin 3.
04, the lower support member 302 is fixed downward. In addition, when bending the lower support member 302 forward as shown in FIG. 11, the lock pin 304 is removed in FIG.
02 forward as shown in the dashed line, and then insert the lock pin 304, the lower support member 3
02 is fixed forward. In this embodiment, there is no need to operate the movable member to pull up the support member, so the movable member on the cargo handling vehicle side does not need to be raised or lowered, and can be fixed to the column, and no movable member driving means on the cargo handling vehicle side is required. It is.

Incidentally, in this embodiment, the support member has a bending structure, but the structure is not limited to this, and the same effect can be obtained as long as the support member can be separated from the ground by itself.

<Effects of the Invention> As is clear from the above, the container of the present invention includes a support member that can be raised and lowered at the rear of the container body, a connecting member and a movable member at the front of the container body, and the operation of the movable member. By providing a transmission means for transmitting the information to the support member, the front part of the container can be moved up and down by the connecting member, the movable member is fixed to the ground, and the relative movement of the movable member with respect to the container body is transmitted. Since the information is transmitted to the support member through the means, the support member is moved up and down, and the rear of the container is moved up and down, the vertical movement of the connecting member and the movement of the support member are synchronized, and the container is held in a horizontal position. It is possible, for example, to load and unload a cargo handling vehicle or the like while maintaining the structure, and therefore pianos, fragile objects, etc. can be transported with a simple and inexpensive configuration.

Furthermore, the container of the present invention can be connected to a transport machine such as a cargo handling vehicle, a ship, a freight train, an airplane, etc. on both sides of the front part via the connecting members provided on both sides of the front part of the container body. Unlike when it is connected to a transport machine only at the center of the main body,
It is not connected to the above-mentioned transport machine in a dogleg shape,
Therefore, the container is prevented from swinging due to such a dogleg-shaped connection, and even in the case of a single load, it does not tilt to one side, improving safety and stability.

Further, in the container of the present invention, since the support member for vertically moving and supporting the rear part of the container is operated by the movable member at the front part of the container, the drive system is provided on the transporting machine side. There is no need to provide the container with any driving means, and the container can be constructed at low cost.

Furthermore, since the container of the present invention transmits the driving force of, for example, a cargo handling vehicle to the container through the connecting member and the movable member at the front of the container, the container can easily move up and down while maintaining a horizontal posture. be able to.
