Description

[Detailed description of the invention] [Industrial application field] This invention is used to guide a container that has been unloaded and suspended by the trolley of a container crane so that it can be loaded onto a trailer chassis waiting below the container crane. The present invention relates to a container guide device.

[Prior Art] This type of container guide device is already known (Japanese Patent Publication No. 53-37616).

This device pivots one end of a guide frame to the leg of a container crane via a bracket, and attaches it to the guide frame in order to load a container suspended by a trolley onto a trailer chassis waiting below the container crane. It is designed to guide you along the way.

[Problems to be Solved by the Invention] However, in the above device, the guide frame that positions the container when it is loaded swings only in the width direction of the trailer chassis. Therefore, since the trailer chassis cannot be positioned in the longitudinal direction, it is necessary to move the trailer chassis to position the container, which poses a problem in that centering (positioning) the container takes time.

Therefore, the present invention was devised to solve the above problems, and its purpose is to position the container in the width direction and longitudinal direction of the trailer chassis, and to align the container on the trailer chassis. An object of the present invention is to provide a container guide device that can perform the following operations in a short time.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a container guide device for guiding a container suspended from a container crane onto a trailer chassis waiting below. The containers are arranged at appropriate intervals along the longitudinal direction of the base frame provided on the legs of the container, and are suspended in an L-shaped cross section via universal joints, and are engaged with the corner portions of the container. A guide frame that guides the descent of a container suspended from the container crane onto the trailer chassis; and a guide frame that is connected to the trailer chassis so that the lower end of the guide frame is removably engaged with a corner of the chassis. and a positioning cylinder that tilts in the longitudinal direction and width direction.

[Operation] When the trailer chassis stops under the container crane, the guide frame is tilted by the cylinder and its lower end is pressed against the corner of the trailer chassis. Next, the container is lowered by a container crane, and the corner portions of the container are engaged with the guide frame and slid along the guide frame. As a result, the container is automatically positioned and loaded onto the trailer chassis.

[Example] An example of the present invention will be described below in detail based on the accompanying drawings.

In Figures 1 to 3, reference numeral 1 denotes a pair of left and right horizontal frames that are hung over the legs 2 of the container crane in a direction perpendicular to the traveling direction of the container crane. A shaped base frame 3 is removably attached.

The base frame 3 is composed of a horizontal portion 3a parallel to the travel direction of the container crane and vertical portions 3b rising vertically from both ends of the horizontal portion 3a, the horizontal portion 3a being formed higher than a trailer chassis 5 waiting in a work area 4 formed between the legs 2 of the container crane. A convex portion 6 for engaging the vertical portion 3b of the base frame 3 with the horizontal frame 1 is formed on the outer side of the upper end thereof, and a receiving portion 7 for engaging the convex portion 6 from above is appropriately formed on the horizontal frame 1, so that the base frame 3 can be removed from and attached to the horizontal frame 1 as required.

The container crane has a horizontal girder (not shown) above and parallel to the horizontal frame 1, and a trolley (not shown), which travels horizontally while suspending a container 8, is supported on this horizontal girder so as to be able to travel freely.
A trailer chassis 5 is provided on the horizontal part 3a of the base frame 3, and waits in the work area 4 for the container 8 to be suspended and transported by the trolley.
Guide frame 9 for guiding loading on top
is hung down via a universal joint 10 so as to be tiltable. In the illustrated example, one horizontal section 3
Four guide frames 9 are provided at appropriate intervals on a, and 9a, 9d or 9b, 9c are used depending on the length of the container, and among these, the outer ones 9a, 9d are arranged along the horizontal part 3a. The position can be adjusted within a predetermined range. That is, among the guide frames 9, the inner guide frame 9
The upper ends of b and 9c are universal joints 10
The upper ends of the outer guide frames 9a and 9d are connected to the horizontal portion 3a by the wheels 1.
It is pivotally supported via a universal joint 10 to a slide frame 12 which is slidably supported via a universal joint 10. outer guide frame 9a,
In order to adjust the position of 9d, a cylinder 13 whose one end is connected to the horizontal portion 3a and the other end is connected to the slide frame 12. Further, the slide frame 12 is positioned and fixed to the horizontal portion 3a via a pin 14 inserted into a pin hole formed in the horizontal portion 3a.

The guide frame 9 is formed to have an L-shaped cross section so as to engage and guide the corner portion 8a of the container 8, and is tiltable in the width direction and longitudinal direction of the trailer chassis 5 using the universal joint 10 as a fulcrum. ing. The universal joint 10 is horizontally spanned between a pair of brackets 15 formed on the slide frame 12 or the horizontal portion 3a, and has a cross-shaped shaft 16 rotatably attached. Above cruciform shaft 1
A bearing 18 that rotates around the axis of the vertical shaft portion 17 of No. 6 is attached.

The free end of the guide frame 9 is attached to the slide frame 12 or the horizontal portion 3a as a means for tilting the guide frame 9 in the longitudinal direction and the width direction of the trailer chassis 5 and pressing the lower end against the corner of the trailer chassis. A positioning cylinder 19 that supports the sides and moves the trailer chassis 5 in the longitudinal direction, and a positioning cylinder 20 that moves the trailer chassis 5 in the width direction are attached.

In the above configuration, when the trailer chassis stops under the container crane, the guide frame 9 is tilted in the longitudinal direction or width direction of the trailer chassis 5 by the positioning cylinders 19 and 20, and the lower end is moved to the corner of the trailer chassis 5. press against the part. Thereafter, the container 8 suspended by the trolley and transported from the sea side to the land side is lowered to be loaded onto the trailer chassis 5 below the container crane. During this descent, the corner portion 8a of the container 8 engages with the guide frame 9, and by lowering the container 8 along the guide frame 9, the container 8 is positioned relative to the trailer chassis 5. In this way, the positioning cylinder 19,
20 is used to move the guide frame 9 in two-dimensional directions, the container 8 on the trailer chassis 5 can be aligned in a short time.

In order to safely lower the container, it is important to check whether the guide frame 9 faces the trailer chassis 5 in its normal position or not.
The container guide device may be provided with a sensor that detects whether there is an obstacle above.

[Effects of the invention] In summary, the present invention provides the following excellent effects.

(1) The lower end of the guide frame engages the corner of the trailer chassis, and the corner of the container engages with this guide frame to guide the container's descent, so the container is lowered along the guide frame. The container can be guided onto the chassis with just a single step, and the container can be easily positioned.

(2) Since the guide frame is formed to have an L-shaped cross section so as to engage with the corner portion of the container and the corner portion of the trailer chassis, the container can be positioned in the longitudinal direction and width direction of the chassis. Cargo handling efficiency can be significantly improved.
