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 an airplane, etc., 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 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; and a relative position of the movable member with respect to the container body. A transmission means is provided for transmitting the movement to the support member to raise and lower the support member, and the movable member is held at a constant height with respect to the ground, and the connecting member is lifted to make the container body approximately horizontal. It is characterized by the fact that it can be raised.

Preferably, the lower end of the support member is 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, for example, a cargo handling vehicle. First, the movable member at the front of the container is fixed to the ground, and the connecting member at the front of the container body is connected to another lifting member to lift the front part of the container body. 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, causing the support member to protrude downward and lifting the rear part of the container body. Therefore, the front and rear parts of the container body are raised horizontally in synchronization with each other.
Then, when the height of the container and the height of the vehicle body become the same height, the container is moved forward while, for example, pulling the connecting portion forward and supporting the rear part of the container on the ground by the support member. 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.

Note that when the container is raised to the same height as the vehicle body of the cargo handling vehicle, for example, the cargo handling vehicle may be moved backward and the container may be loaded onto the vehicle body without pulling the connecting member forward. .

Furthermore, instead of operating the movable member and lifting the support member from the ground, the support member may be bent and fixed so that the support member does not support the ground.

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

The container with the above configuration operates as follows.

Now, the cargo handling vehicle 45 and the container 1 are in the state shown in FIG. In this state, the hook 63 of the cargo handling vehicle side coupling member 61 is engaged with the pin 13 of the container side coupling member 11, and the container side movable member 16 is engaged with the pin 13 of the container side coupling member 11, and the container side movable member 16 is The pin 19 is engaged. Then, the cargo handling vehicle side connecting member 61 is raised by extending the hydraulic cylinder 71, and the cargo handling vehicle side movable member 91 is kept stationary with respect to the ground with the hydraulic cylinder 97 inactive. Then, the front part of the container 1 is lifted by the cargo handling vehicle side connecting member 61 via the container side connecting member 11, and at the same time, the rear part of the container 1 is lifted by the supporting members 3, 3 as follows. That is, since the container side movable member 16 is stationary with respect to the ground due to the stationary cargo handling vehicle side movable member 91, when the container body 2 rises, the container side movable member 16 moves against the container body 2. The movement is transmitted to the support member 3 by the chain 21 and the chain 40, and the support members 3, 3
protrudes downward and raises the rear part of the container 1 as shown in FIG. 5b. That is, the front part of the container 1 is lifted up by the connecting member 13, 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. Then, container 1 is transported to cargo handling vehicle 45.
When the level is the same as that of the vehicle body, 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 stopped.
is driven to move the column device 51 forward, and as shown in FIG. 3c, the container 1 is placed on the guide rollers 99 and moved forward. 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, it is pulled through the container-side connecting member 11 and the container-side movable member 16. Thereafter, with the container 1 placed on the cargo handling vehicle 45, the hydraulic cylinder 97 of the cargo handling vehicle 45 is contracted, the cargo handling vehicle side movable member 91 is raised, the container side movable member 16 is raised, and the container side movable member 16 is raised. Raise the support member 3 from the ground,
The state is set as shown in FIG. 5d.

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 member 11, and at the same time moves the container-side movable member 16 relative to the container body 2 in synchronization with the chain 21, 31, 40 converts the lifting or lowering movement of the support member 3 into a lifting or lowering movement of the container 1.
The rear part of the container 1 can be lifted or lowered, so that 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 connects the cargo handling vehicle side movable member 91 and the container side movable member 16, and By simply connecting the cargo handling vehicle side connecting member 61 and the container side connecting member 11, the container 1 can be easily loaded and unloaded while maintaining a horizontal posture. Therefore, even if the container 1 is loaded with pianos, furniture, fragile items, etc., it can be loaded and unloaded without any problem.

6 and 7 show modified examples of the container, in which the chains 21, 31, 40 as the transmission means in FIG. 1 are basically converted into hydraulic piping. That is, this container is provided with pillar-shaped support members 103 on both rear sides of the container body 2, which are guided by guide members 105 and can be moved up and down. 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 a bracket is attached to the lower end of the support member 103. 108
The roller 107 is attached via the. on the other hand,
The movable member 116 is a flat plate 1 having a hole 121 in the center.
It is composed of 20 parts. The connecting member 11 has the same construction as the connecting member shown in FIG. The movable member 116 is connected to the tips of the piston rods of the hydraulic cylinders 123, 123, and the lower part, that is, the head side of the hydraulic cylinder 123 is connected to the hydraulic cylinder 1.
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,
By lowering the movable member 116, the support member 1 is moved together with the piston rod of the hydraulic cylinder 106.
03 is lowered, and conversely, when the movable member 116 is raised from the lowered state, oil is supplied to the rod side of the hydraulic cylinder 106 through the pipe 140, and the piston rod of the hydraulic cylinder 106 is retracted. That is, the container shown in FIGS. 6 and 7 differs from the embodiment shown in FIG. 1 only in that the operation of the movable member 116 is transmitted to the support member 103 by a hydraulic system instead of a chain drive system. It is something.

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, as shown in FIG. 11, when bending the lower support member 302 forward, 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. Furthermore, the container chain 40 and sprockets 42, 43 are unnecessary.

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.

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 can be connected to a transport machine, such as a cargo handling vehicle. , a ship, an airplane, etc., the container does not need 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.
