The present invention relates to a wing-type container in which cargo can be loaded and unloaded from a side surface in a container for transporting packed cargo.
More specifically, the present invention relates to a method and an apparatus for opening and closing a wing of a wing type container.

When loading / unloading a container, a wing-type container with the container openable and closable is used for transporting large loads that cannot be unloaded even if the rear door is opened.

As such a wing type container, for example, in Japanese Patent Application Laid-Open No. 08-169239 (Patent Document 1), a light weight with a high internal height inside the container is maintained without changing the shape of the container during handling or transportation. Wing-type containers have been proposed.

The wing-type container of this Patent Document 1 is a general one, and an L-shaped upper section is formed along both side surfaces of the center beam arranged at the center of the upper portion of the container. A wing is attached through a hinge so as to be freely opened and closed.

On the other hand, Japanese Patent Laid-Open No. 11-093521 (Patent Document 2) proposes a wing door opening / closing mechanism for a container that is easy to open and close wings and is not easily affected by wind.
This container wing door opening / closing mechanism is a wing door in which the side surface of the container is divided into two vertically, and the lower wing door is pivotally attached to the container bed so that the lower end of the lower wing door can fall down.
The upper wing door is slidable along a guide track disposed above the container.
The lower wing door and the upper wing door are connected by a wire via a pulley, and the upper wing door is configured to be pulled into the container in conjunction with the fall of the lower wing door.

Japanese Patent Laid-Open No. 08-169239 (paragraph 0011, FIG. 2) JP-A-11-093521 (

Claims

2, 4 and 5) Japanese Patent Laid-Open No. 2001-213497 (Claims, FIGS. 1 and 4)

In the wing-type container described in Patent Document 1, the upper wing that is rotatably disposed on both the left and right sides of the center beam is an integral type that serves as both a part of the upper surface wall and the side surface.
A hydraulic cylinder for opening and closing the upper wing (hereinafter also simply referred to as “driving device”) is usually disposed at the upper end of the front and rear wall surfaces of the container.

Such a drive device for opening and closing the upper wing inevitably increases the weight of the upper wing as the container length increases to 30 feet and 40 feet. Need.

Furthermore, in order to open and close the heavy upper wing, it is necessary to arrange the drive device on the upper side of the side surface before and after the container, so there are problems to be solved such as occupying a place for installation.

On the other hand, the container wing door opening / closing mechanism described in Patent Document 2 includes a mechanism for opening and closing the upper wing door and the lower wing door inside the container.
That is, in the container wing door divided into two parts, the lower wing door has its lower end pivoted to the container bed so as to be able to fall down, and the upper wing door follows the guide track disposed above the container. And is slidable.
The lower wing door and the upper wing door are connected by a wire via a pulley, and the upper wing door is configured to be pulled into the container in conjunction with the fall of the lower wing door.

Therefore, it cannot be said that the wing door opening / closing mechanism is simple, and there is a problem from the viewpoint of effective use inside the container, and since it is a mechanical type that opens the upper wing, it can be used for large containers. Can not.

In the container disclosed in Patent Document 3, when the upper wing having an L-shaped cross section is opened and closed in the vertical direction, the weight of the upper wing inevitably increases as the length of the container increases. Are relatively heavy, a large drive is required.

Furthermore, when an abnormal situation occurs in the drive device due to a failure of the hydraulic cylinder or running out of oil, and the use becomes impossible, the upper wing cannot be actually opened and closed.
As a result, the loading and unloading of the cargo has substantially stopped, which may have a significant impact on the transportation of the cargo.

In particular, the drive device comprising a hydraulic cylinder for opening and closing the upper wing in

Patent Document

1 or 3 requires an oil tank, a pump for supplying oil to the cylinder, and a motor for driving the pump. The enlargement of itself is inevitable.
Furthermore, when an abnormality occurs in the drive device, there is a big problem that cargo cannot be loaded or unloaded.
Furthermore, since a large force is required for initial driving when the upper wing is opened and closed, there is a problem that the driving device is enlarged in order to obtain the output.

In view of the current situation, the present invention
1) When opening and closing the upper wing of a container using a hydraulic cylinder, reduce the burden on the hydraulic cylinder during initial driving 2) Simplify the configuration of the hydraulic cylinder 3) In the unlikely event of failure or oil Even when some kind of abnormality occurred in the drive device such as cutting, and it became impossible to use it, we intensively studied the issues required of the container, such as the development of means that can open and close the upper wing.

As a result, by adopting a mechanism that interposes a rotation support member between at least one of the front and rear side surfaces constituting the container and the upper wing, and extends the rotation support member simultaneously with driving of the hydraulic cylinder In particular, it succeeded in reducing the load applied to the hydraulic cylinder at the start of driving.

At that time, the drive device for the hydraulic cylinder is configured only by an oil tank and a pump with a built-in gear, thereby making it possible to reduce the weight, simplify and reduce the cost of the drive device.
At the same time, by configuring the drive device so that it can be driven manually or with a tool such as an electric drill, the drive device can be operated in the event of a failure.

That is, according to the present invention, when the upper wing is opened and closed, the initial load applied to the drive device can be reduced as much as possible, and even if a problem occurs in the drive device, the drive device can be moved with a simple tool. It is an object of the present invention to provide a method and an apparatus for opening and closing a wing-type container that can be opened.

It is comprised by the container main body which consists of the lower wing 3 (not shown in the other side) rotated to an up-down direction along.

In this embodiment, the

upper wings

2 and 2 are rotated in the vertical direction via the support shafts 9 arranged on both sides of the center beam 11, but the

upper wings

2 and 2 are provided directly on the center beam 11. May be.

Of the side surfaces attached to the front and rear edges of the bottom plate 5, the side surface 4 arranged on the rear side is a portal frame, and a pair of doors that are opened and closed to the left and right are mounted.

Each of the upper wings 2 closes an upper surface wall 2a having a width of ½ on the short side of the side surface 4 and at least ½ or more of left and right openings in the longitudinal direction of the container 1. It is comprised from the upper side surface 2b which can do.

As apparent from FIG. 2,

brackets

14 and 14 are attached to one end of the upper surface wall 2a constituting each upper wing 2, respectively.
In this embodiment, the bracket 14 is provided only at one end edge, but may be provided at both end edges.

The lower wing 3 is composed of a side surface other than the upper side surface 2b, and is rotatably attached to each side edge of the bottom plate 5 of the container 1 via hinges H.

The base end portion in the longitudinal direction of the upper surface wall 2 a constituting the upper wing 2 is pivotally supported by the

support shafts

9, 9 arranged on the left and right sides along the center beam 11.
The front and rear end portions of the support shaft 9 are attached to the piston rod of the hydraulic cylinder 8 disposed at the upper end portion of the side surface 4 located in front of the container 1 via

brackets

13 and 13, respectively.

The left and right

upper wings

2 and 2 are lifted upwards around the

support shafts

9 and 9 by driving

hydraulic cylinders

8 and 8 as drive devices, respectively.

Specifically, the

hydraulic cylinders

8 and 8 are connected via a hydraulic pipe 12 and a hydraulic unit 15 disposed in the lower part of the container 1 as is apparent from FIG.
Accordingly, by operating the hydraulic unit 15 to drive the

hydraulic cylinders

8 and 8, the

upper wings

2 and 2 are rotated in either the vertical direction.

The hydraulic cylinder 8 is a double-acting cylinder, and controls the operation of the hydraulic cylinder 8 by switching the oil flow.
The drive source of the hydraulic cylinder 8 is composed of a pump with a built-in gear and an oil tank (both not shown), and as is apparent from FIG. 2, a hydraulic unit disposed below the container 1 15 is built in.

The hydraulic unit 15 incorporating this drive source is configured to drive the

hydraulic cylinders

8 and 8 by simple power transmission means such as a hand drill or an electric drill.
More specifically, the cylinder rod of the hydraulic cylinder 8 is extended or contracted by driving a pump with a built-in gear with a manual tool such as a hand drill or an electric drill and switching the oil piping of the oil tank. Is.

The upper end of the side surface 4 in front of the container 1, specifically, the non-movable portion at the upper end of the side surface 4 is attached to the base end portion of the cylinder tube of the hydraulic cylinder 8 via a bracket (not shown). Yes.
On the other hand, the base end portion of the rotation support member 7 that supports the upward rotation of the upper wing 2 is attached to the side surface 4 in the vicinity of the support shaft 9 via a bracket (not shown). .

The rotation assisting member 7 has a compression coil spring mounted on the outer peripheral portion of a shaft member having a required diameter and length having attachment portions at both ends, and the tip portion of the rotation supporting member 7 is the upper portion. The wing 2 is attached to a bracket 14 attached to the upper surface wall 2a.

The compression coil spring in the rotation support member 7 always urges the upper wing 2 upward.
When the upper wing 2 is rotated upward, the rotation support member 10 is also rotated upward at the same time, and the compression coil spring is extended by the biasing force, so that the upper wing 2 is supported by the rotation support member 7. Can be rotated with a light force.

As a result, when the upper wing 2 is rotated upward, the load applied to the hydraulic cylinder 8 is reduced in the initial drive that requires the most power, so that it is not necessary to increase the size of the hydraulic cylinder 8 itself.

In addition, in the rotation of the upper wing 2 in the closing direction, the upper wing 2 rotates against the urging force of the rotation support member 7.
At that time, the weight of the upper wing 2 also acts, so that it can be rotated by only the pulling force of the piston rod of the hydraulic cylinder 8 without requiring a large force.

In the present invention, since the rotation support member 7 is interposed between the upper wing 2 and the side surface 4 of the container 1, when the upper wing 2 is opened and closed, the rotation support member 7 acts to make it relatively small. Even this hydraulic cylinder can be opened and closed easily and smoothly.

The drive source of the hydraulic cylinder 8 is constituted by a pump with an oil tank and a gear built therein, and the pump is driven by a hand drill or an electric drill. be able to.

The oil tank and the pump with a built-in gear, which are the driving source of the hydraulic cylinder 8, are collectively stored in the hydraulic unit 15 and linked to the hydraulic cylinder 8 by the pipe 12, so that the driving device can be made compact. it can.

In the wing type container 1 of the present invention having such a configuration, the drive source for driving the hydraulic cylinder 8 is constituted only by a pump and an oil tank with a built-in gear. The possibility of abnormalities such as cutting is extremely low, and continuous use for a long time is possible.

In addition, the pump is not driven by a motor, and can be driven by simple power transmission means such as a hand drill or an electric drill. The upper wing 2 can be reliably opened and closed, and there is no hindrance to loading and unloading.

A pair of left and right rotation assisting members 7 having such an action may be disposed at predetermined positions (upper end portions of the side surfaces) on either one of the side surfaces 4 and 4 of the container 1.
However, in the case of a large vehicle exceeding 30 feet, as shown in FIG. 3, it is preferably disposed on all of the front and rear side surfaces 4, 4 of the wing type container 1.

On the other hand, in the present invention, the lower wing 3 employs a configuration in which the lower wing 3 is rotated by a rotation assisting auxiliary member 10 disposed on one side of the front and rear side surfaces 4 and 4.

That is, as shown in FIG. 4, this rotation assisting auxiliary member 10 engages a lower pipe P2 whose upper part opens in an upper pipe P1 whose lower part opens, so that it can slide and cannot be detached. A coil spring (not shown) is provided so as to penetrate the upper pipe P1 and the lower pipe P2.

The base end of the coil spring is fixed in the upper pipe P1, the tip is pulled out from the tip of the lower pipe P2, and the tip protrudes in the horizontal direction near the lower portion of the end face of the lower wing 3. This is engaged with the shaft member 16 provided.
Therefore, a biasing force in the contraction direction of the rotation assisting auxiliary member 10 is always applied to the shaft member 16.

As a result, the lower wing 3 is not likely to be inadvertently opened due to the action of the fastening tool spanned between the upper wing 2 and the urging force of the rotation assisting auxiliary member 10.

In this state, when the lower wing 3 attached to the bottom plate 5 via the hinge H is rotated downward, the lower pipe P2 engaged with the shaft 16 is connected to the shaft via the coil spring. Since they are linked, the coil spring extends downward and the lower wing 3 can be smoothly opened at an angle of approximately 180 °.

When the lower wing 3 is closed, the front edge of the lower wing 3 is lifted upward.
At that time, one pipe P2 constituting the rotation assisting auxiliary member 10 is pulled up into the pipe P1 by the urging force in the contracting direction of the coil spring incorporated therein, so that the lower wing 3 is smoothly moved along the bottom plate 5. Can stand.

Furthermore, in the present invention, the bottom plate 5 is formed in a honeycomb shape in order to reduce the weight of the container 1 and maintain sufficient strength.

Specifically, although not shown in the drawing, a plurality of auxiliary rails having a required width are provided between rectangular bottom frames having a required size at appropriate intervals, and adjacent auxiliary rails are connected to each other. The bottom plate is configured by integrally connecting with a material and attaching a bottom plate to the upper surface thereof.

The width of the auxiliary rail is not constant, and it is preferable to use a wide auxiliary rail for the portion where the load is applied.

In this embodiment, the left and right side surfaces of the container 1 are composed of an upper wing 2 whose upper part is integrated with a part of the upper surface wall 2a, and a lower wing 3 that can be opened and closed along the side edge of the bottom plate 5. Explained in the format.
However, the specific structure of the container 1 is not limited as long as the left and right side surfaces are opened simultaneously or at least one of the left and right side surfaces along the longitudinal direction is opened.

A method and apparatus for opening and closing a wing-type container according to the present invention includes a rotation support member interposed between the upper wing and the container, and enables smooth opening and closing of the upper wing by supporting the driving of the hydraulic cylinder. The hydraulic cylinder that opens and closes the wing is composed of a pump with a built-in oil tank and gear, and is operated by a drive source that can be driven manually or with a simple tool such as an electric drill, so there is little failure and loading and unloading can be performed at any time. Since it becomes possible, it is widely used in the transportation industry.
