[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container spreader for a forklift truck.

[0002]

2. Description of the Related Art Conventionally, when the height of a container becomes higher than a target, it becomes impossible to visually confirm the height of the container as shown in FIG. He relied on his intuition.

[0003]

[Problems to be Solved by the Invention] In recent years, as the height of the container yard has increased, the operation of aligning the twist lock pin and the upper hole of the container at a position far away from the operator has increased. In order to start over, it was necessary to make several holes, and because of the upward work, the neck became tired and the efficiency became poor.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and in a container spreader device of a forklift truck, a small TV camera is mounted near a twist lock pin 2 at the tip of a left and right boom, and the image is projected. The left and right images are fixed on the dashboard, the images are displayed on the two left and right monitors, and the operator locks the container upper holes displayed on the two left and right monitors, so that the twist lock pin It is designed to fit into the upper hole.

[0005]

The present invention adopts the above-mentioned structure, and the position can be adjusted while confirming the position of the hole with the monitor, so that even a beginner can easily fit the twist lock pin once.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1A shows a small T provided on the boom tip 6.
V-camera 1 with container upper hole 5 at the top of container 8
Is displayed on the monitor 3 fixed on the dashboard 4 shown in FIG.

FIG. 2 is an enlarged view of the displayed left and right monitor images. In the enlarged screen, an alignment mark 10 is displayed on the screen. By aligning the upper hole 5 of the container with the intersection of the vertical and horizontal alignment marks 10, the twist lock pin 2 just fits into the upper hole 5 of the container. Has been adjusted.

The small TV camera 1 has a CCD camera (CH
When ARGE-COUPLED DEVICE is used, many advantages such as good sensitivity, excellent seismic resistance, no adjustment, and low price can be utilized.

FIG. 3 is a wiring diagram in which the wiring 12 of the TV camera is also provided together with the hydraulic piping 11 to the twist lock pin 2, and the wiring of the TV camera is adapted to the movement or elevation of the boom of the container spreader device. There is no disconnection such as insertion. FIG. 4 shows a front view of the container spreader device.

Since the present invention is constructed as described above, the following remarkable effects are obtained. (A) By aligning the two monitors in the driver's seat that project the left and right suspension positions in the left-right direction, and arranging the two monitors close to each other, there is no risk of misunderstanding because they are in the same direction as the actual direction. The operability is greatly improved because the positioning can be performed while checking the two monitors almost simultaneously. (B) It is not necessary to swing the head to the left or right to check the suspension position on the left and right sides, thereby reducing driver fatigue. (C) Conventionally, the driver's seat of a forklift was provided at a high position so that the left and right hanging positions of the container could be visually checked. However, in the present invention, the driver's seat is not necessarily provided because the hanging position can be easily confirmed by a TV monitor. It is not necessary to raise the height, and it becomes possible to provide a driver's seat closer to the ground. As a result, the following secondary effects can be obtained. (1) It is not necessary for the driver to climb to a high position when getting on and off, which helps to reduce operator fatigue. (2) Since the danger of falling from a high position is eliminated, the safety of the driver when getting on and off is improved. (3) The driver is no longer afraid of high places. (4) Since the position of the center of gravity on the vehicle side is lowered, the stability of the vehicle is improved.
