DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a windbreak device in a cargo handling facility provided in a port facility, for example.

[0002]

2. Description of the Related Art A conventional windbreak device for cargo handling equipment is disclosed, for example, in Japanese Patent Application Laid-Open No. 3-61293. As shown in FIG. 4, this is slidably movable on a building 51 erected on a quay 50 (a protruding roof) 52.
A foldable boom 54 having a stay 53 is disposed below the movable roof 52.
A supporting body (wind receiving beam) 55 is hung down, and a covering body 56 that is rolled up or folded along the supporting pillar 55 is provided.

[0003]

In the above-mentioned conventional construction, the boom 54 is raised from the folded state in the event of wind and rain, the movable roof 52 is slid from the building 51 to above the sea surface, and the column 55 is moved downward to cover the body. 55 is used so as to extend toward the sea surface. In addition, for the cargo handling operation, the folding crane girder provided inside the building 51 after the above operation is extended.

As is apparent from the above, in the above configuration, the number of movable parts such as the movable roof 52 is extremely large, and a complicated mechanism for storing the movable parts in the building 51 is required, so that maintenance is difficult. There is a problem that is.

[0005] Therefore, an object of the present invention is to provide a rain protection device in a cargo handling facility capable of solving the above-mentioned problems.

[0006]

Means for solving the problems in the present invention are as follows. A building is erected on a quay, and the roof of the building is extended above the sea surface to form a rainproof part. On both sides of the arm, a pair of arms are rotatably supported in a vertical plane, and a windproof wall is rotatably supported via a spindle between the ends of the arms. A cylinder device for rotating the body by a predetermined angle around the support shaft is provided, and the arms are stored in a storage position in which the windproof wall is positioned above the roof, and the windproof wall is positioned above the sea surface. A rotating means is provided for switching to the windproof and rainy position.

[0007]

In the above construction, when the cargo handling operation is not performed, or when the weather is fine or when there is no wind, the rotating means and the cylinder device 1
7 is driven so that the windproof wall 15 is positioned above the roof 4 and the cargo handling operation is performed in rainy weather or when there is a wind. When the windproof wall 15 is separated from the roof 4 by driving the arm 6A, the arm 6A,
Since the arm 6A pivots to the sea surface side, the arms 6A and 6B are rotated to an appropriate position and then fixed, and the cylinder device 17 is driven to erect the windproof wall 15 on the sea surface 3. In this way, the cargo handling work place of the building 2 is set to the windproof and rainy posture 18B covered from the side.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a windbreak device in a cargo handling equipment according to the present invention will be described with reference to FIG. 1 showing an overall side view showing a storage posture of an arm, FIG. This will be described with reference to the drawings.

In a windbreak apparatus for cargo handling equipment according to an embodiment of the present invention, a building 2 is erected on a quay 1, and a roof 4 having a rainproof portion 4 A disposed above the sea surface 3 is fixed to the building 2. ing. A windproof rain shutter 4B is attached to the front and rear lower sides of the rainproof part 4A.
B can be folded up and down with respect to the sea surface 3 by appropriate means.

As shown in FIG. 3, a pair of arms 6A and 6B are erected along the front and rear walls 5A and 5B of the building 2, and the base ends 7 of the arms 6A and 6B as shown in FIG.
Is rotatably supported in a vertical plane via a horizontal shaft 9 attached to a bracket 8 fixed to the quay 1,
The upright height H1 of the arms 6A, 6B is formed higher than the height H2 of the building 2 up to the roof 4. Further, the arms 6A and 6B are provided with a V-shaped body 10 attached to the horizontal shaft 9 and an extended body 13 formed integrally with the upper end of one end 11 of the V-shaped body 10 and parallel to the other 12 of the V-shaped body 10.
And a connecting body 14 which is provided between the upper ends of the V-shaped body 10 and between the upper end 13a of the extended body 13 and the other 12 of the V-shaped body 10.

Arm fixing pins 13b and 14a for positioning the arms 6A and 6B are attached to an intermediate portion of the connecting member 14 and a lower portion of the extending member 13. One side of the windproof wall 15 is rotatably supported via a support shaft 16 across the upper end 13a of the extension body 13, and the other 12 of the V-shaped body 10 and the windproof wall are supported. A cylinder device 17 for rotating the windproof wall 15 around a support shaft 16 by a predetermined angle is connected between the cylinder device 17 and the position 15.

The arms 6A and 6B are placed in the storage position 18A where the windproof wall 15 leans against the roof 4.
A rotating means 20 is provided for rotating from the storage position 18A in the clockwise direction 19 to switch the windproof wall 15 to the windproof position 18B standing upright on the sea surface 3 as shown in FIG. The rotating means 20 is rotatably supported on the roof 4 via a base 21, and is wound around the winding drum 22 and attached to the extension body 13. And a winding drive unit (not shown) for winding the wire rope 23.

The quay 1 is provided inside the building 2.
A crane 24 for performing cargo handling work on the ship S berthed is provided, and the height of the crane girder 25 for guiding the traversing trolley 25a does not interfere with the mast S1 of the ship S when the ship S berths. Set to height.

Next, the operation will be described. When the cargo handling work is not performed, or when the weather is fine, or when there is no wind, the wire rope 23 is wound around the winding drum 22 and the cylinder device 17 is driven to drive the windproof wall 15. Put the other side on the top of the roof 4,
The arm fixing pin 14a is locked to the building 2 side, and the arms 6A and 6B are set in the upright storage posture 18A.

When the cargo handling operation is performed in rainy weather or when there is a wind, the cylinder device 17 is first driven to separate the other side of the windproof wall 15 from the roof 4 from the storage position 18A. The lock of the arm fixing pin 14a is released, and the winding drum 22 is rotated to rotate the wire rope 23.
Put out.

Then, since the weight of the windproof wall 15 acts on the arms 6A and 6B, the arms 6A and 6B rotate clockwise 19 around the horizontal axis 9. And arm 6 to a predetermined position
After rotating A and 6B, the rotation of the take-up drum 22 is stopped, the arm fixing pin 13b is locked to the building 2 side to fix the arms 6A and 6B, and the cylinder device 17 is driven again to prevent the rotation. The weathering wall 15 is placed upright on the sea surface 3, and the cargo handling work place of the building 2 is covered from the side to have the windproof posture 18 B, and the cargo handling workplace is covered with the windproof rainfall wall 15 from the side. Also lower the windproof shutter 4B,
This covers the cargo work area from the front and rear.

[0017] By covering the cargo handling work area from the side and front and rear portions in this manner, cargo handling can be performed without exposing the load and workers to the wind and rain even in the event of wind and rain. In addition, the windproof wall 15 is placed on the roof 4 when not in use, and the arm 6A, 6B is rotated around the horizontal axis 9 to drive the cylinder device 17 when in use. State, so that the configuration of the entire apparatus is simple and maintenance is easy.

[0018]

As is evident from the above description, according to the present invention, a pair of arms are rotatably supported in a vertical plane on both sides of a building erected on a quay, and both arms are rotated by a rotating means. By rotating, the cylinder device was driven, and the arm was switched from the storage position in which the windproof wall was located above the roof to the windproof position in which the windproof wall was located above the sea surface. In addition, the cargo handling operation can be performed with a small number of movable parts without exposing the worker and the load to the wind and rain, so that the configuration of the entire apparatus is simplified and the maintenance is easy.
