BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for a container crane.

[0002]

2. Description of the Related Art FIG. 3 is a schematic view showing an example of a general container crane, in which 1 is a container ship moored to a quay 2, and between the container ship 1 and the quay 2. The container crane 3 loads and unloads the container 4 as a suspended load.

In the illustrated container crane 3,
A girder 6a located on the land side and a boom 6b extending to the sea side are provided above the leg portion 5 that can travel along the quay 2, and the trolley 7 can traverse along the girder 6a and the boom 6b. It is installed in.

On the trolley 7, a spreader 8 as a suspending tool for holding the container 4 is provided with a head block 9.
The hoisting rope 10 is suspended via a hoisting rope 10, and the hoisting drum 10 in the machine room 11 hoists and hoists the hoisting rope 10 to raise and lower the spreader 8. .

Thus, for example, when the container 4 is unloaded from the container ship 1 by using the container crane 3, the spreader 8 is hung from the trolley 7 which is traversed on the container ship 1 to grip the container 4. Then, the spreader 8 is rolled up to traverse the trolley 7 to the hanging position on the quay 2, and then the spreader 8 is rolled down to hang the container 4 at a predetermined position on the quay 2. It will be.

The trolley 7 used in such a container crane 3 is designed to be traversed by a rope towing system using a traverse drum 13 in a machine room 11. More specifically, as shown in FIG. , The traverse ropes 14 and 15 fixed to one end side (sea side) of the trolley 7 are the boom 6b.
Of the sheaves 16 and 1 arranged on the tip side (sea side) in the longitudinal direction of the
After being hung around 7, the sheaves 18 and 19, the sheaves 22 and 23 that are moved up and down by the hydraulic cylinders 20 and 21 for tension adjustment, and the sheaves 24 and 25 to the traverse drum 13 in the machine room 11. The traverse ropes 14 and 1 that are wound and are wound around the traverse drum 13.
Traverse ropes 26 and 27 wound in the direction opposite to 5
Is hung around the end sheaves 28 and 29 arranged on the longitudinal end side (land side) of the girder 6a, and then hung on the equalizer sheaves 30 and 31 attached to the other end side (land side) of the trolley 7. It is rotated and connected and fixed to the trolley 7 by the wire clip 32.
Is rotated clockwise in FIG. 4, the traverse ropes 14 and 15 are wound and the traverse rope 2
6, 27 are fed out, the trolley 7 traverses to the sea side along the girder 6a and the boom 6b, and the traverse drum 13
4 is rotated counterclockwise in FIG. 4, the traverse ropes 14 and 15 are unrolled and the traverse ropes 26 and 27 are wound up, so that the trolley 7 is landed along the girder 6a and the boom 6b. It is designed to be rampant.

On the other hand, as shown in FIG. 5, the hoisting rope 10 has two hoisting drums 12 arranged side by side in a machine room 11 (see FIG. 3), two hoisting drums 12 in total, for a total of four hoisting ropes. The hoisting rope 10 that has been wound up and unwound from each hoisting drum 12 is wound around end sheaves 33 and 34 arranged on the longitudinal base end side (land side) of the girder 6a,
Guide sheaves 35 and 36 attached to the other end side (land side) and one end side (sea side) of the trolley 7, and the head block 9
Guide sheaves 37, 38 attached to the other end side (land side) and one end side (sea side) of the above, and said guide sheaves 35, 36
And the equalizer sheaves 41, 42 attached to the longitudinal end side (sea side) of the boom 6b in the longitudinal direction of the boom 6b.
The hoisting drum 12 is connected and fixed to the front end side (sea side) of the boom 6b by 44, for example,
When it is rotated clockwise in FIG. 5, the hoisting rope 10 is taken up, the head block 9 and the spreader 8 suspended from the trolley 7 rise, and the hoisting drums 12 are, for example, in FIG. When rotated counterclockwise,
The hoisting rope 10 is paid out, and the head block 9 and the spreader 8 suspended from the trolley 7 can be lowered.
