DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bridge-type crane loading / unloading facility, and more particularly, to a bridge-type crane loading / unloading system in which a bridge-type crane is used for loading / unloading in harbors. Related to rainproof facilities.

[0002]

2. Description of the Related Art One of the cargo handling methods for loading or unloading cargo on a ship at a port is a method using a bridge crane. This bridge-type crane is configured such that a horizontal girder extending horizontally over the sea and on which a trolley travels is arranged above a portal that can travel along a quay. Then, the horizontal girder is moved on a ship moored on the quay, and the cargo is loaded or unloaded by the hanging tool suspended from the trolley.

[0003] By the way, the loading and unloading of this bridge type crane is usually performed on the open-air. For example, when the cargo requires waterproofing, the loading and unloading operation must be stopped in rainy weather. And the efficiency of cargo handling equipment will be reduced. Traditionally, to solve this problem,
A method of covering a bridge-type crane with a curtain or the like and a method of pulling a ship into a large building for cargo handling have been proposed.

[0004]

In the above-mentioned method of covering a bridge-type crane with a curtain, there is a danger that rain will enter from the hatch of the ship and wet the cargo. There is a problem that construction is required and construction costs are high.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and is provided so as to extend horizontally on the sea above a portal capable of running along a quay, and A bridge-type crane on which a horizontal girder on which a trolley travels is arranged, and a ship moored below the horizontal girder, a roof is arranged on the upper surface of the portal and the horizontal girder, and a side portion of the portal, and A first curtain is disposed on a side of the horizontal girder except for an extended portion, and a second curtain is provided on a lower side of the horizontal girder and a lower side of the horizontal girder except for a portion for attachment to the portal.
To provide a rain-proof facility for loading and unloading a bridge-type crane in which a third curtain is arranged on the ship, and one end of the third curtain is connected to the lower end of the second curtain. Is what you do. Preferably, each of the first, second, and third curtains is configured to be detachable, that is, a so-called portable system.

[0006]

[Operation] In such a bridge-type crane loading and unloading equipment, the bridge-type crane is covered with a first curtain and a second curtain, and the hatch of the ship, specifically, the hatch of the ship, is covered with a third curtain. Covered. Further, since one end of the third curtain is attached to the lower end of the second curtain, at least communication between the portal of the bridge crane, the lower part of the horizontal girder, and the cargo hold of the ship is possible. A separate section is formed and cargo can be handled. And
This section is not changed by the movement of the portal, that is, the change in the relative position between the ship and the bridge-type crane, so that all cargo holds of the ship can be handled.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a rain-proof facility for loading and unloading a bridge-type crane according to the present invention will be described below with reference to FIGS.
1 is a side view, FIG. 2 is a view taken along the line AA of FIG. 1, and FIG.
FIG. 4 is a perspective view of FIG. Reference numeral 1 denotes a bridge-type crane. The bridge-type crane 1 includes a portal 4 that runs on a rail 3 laid along a quay 2 and a horizontal girder 5 that extends horizontally on the portal 4 toward the sea. A trolley 7 which hangs the hanging tool 6 and traverses the horizontal spar 5 is arranged on the horizontal spar 5, and the horizontal spar 5 is bent upward at a refraction point 8 as shown by a dotted line when not in use. It has become.

As shown in FIG. 4, roofs 9 and 10 are respectively provided on the upper surfaces of the portal 4 and the horizontal girder 5, and the roofs 9 and 10 are preferably detachably constituted by a canvas or the like. You. Reference numeral 11 denotes a first curtain provided on a side portion of the portal 4, specifically, a side portion of the horizontal girder 5 except for the mounting portion 12.
An opening 14 through which a freight carrier 13 such as a truck runs is formed at a lower portion of 1.

Reference numeral 15 denotes a second curtain disposed on the lower side of the horizontal girder 5 and on the lower side excluding the portion for attaching to the portal 4. Is mounted with a bar 16 as a double hanger. The second curtain 15 can be wound and unrolled by a winding device (not shown). That is, FIG.
As shown in FIG.
The height of the lower end of 5 can be adjusted.

Reference numerals 18a and 18b denote third curtains arranged on the ship 17, and the third curtains 18a and 18b
18b is connected at one end to the lower end of the second curtain 15, preferably in a detachable manner, and at the other end to the winding devices 19a, 1
9b. This winding device 19a, 19
b shows the mounting plate 2 on the base 20 as shown in FIG.
The base 20 is attached to a bracket 24 attached to a ship deck 23 by welding or the like by means of bolts 25. The mounting plate 21 and the base 20 are mounted by bolts 26. The mounting plate 21 is provided with a plurality of bolt holes 27, and the winding devices 19a and 19b are applied to several types of ships having different ship widths. Considered as possible.

In such a rainproof facility for loading and unloading a bridge-type crane, the first curtain 11, the second curtain 15, and the third curtain
Curtains 18a, 18b are made of a flexible material such as canvas, and these provide a rainproof compartment 29 in which the lifting gear 6 can be moved under the horizontal girder 5 of the portal 4 and in the cargo hold 28 of the ship 17. It is formed and can be loaded in the rain-proof state.

When the cargo handling of the predetermined cargo hold 28 of the ship 17 has been completed and the cargo handling of another cargo hold 28 'is to be performed, the portal 4 is moved in the direction of the arrow S, and the third curtain 18a is rolled in. On the other hand, by unwinding the third curtain 18b, the rainproof compartment 29 is formed in the cargo hold 28 '. Of course, the first curtain 11 and the second curtain 11
The curtain 15 and the third curtains 18a and 18b are detached for cargo handling except in the case of rainy weather.

[0013]

According to the present invention, the rainproof equipment for loading and unloading a bridge-type crane according to the present invention includes a horizontal girder 5 extending horizontally on the sea above a portal 4 which can travel along the quay 2 and on which a trolley 7 travels. The bridge-type crane 1 and the ship 17 moored below the horizontal girder 5 are arranged. A roof 10 is arranged on the portal 4 and the upper surface of the horizontal girder 5. A first curtain 11 is disposed on a side portion of the horizontal girder 5 except for an extended portion, and a second curtain is provided on a lower side portion of the horizontal girder 5 and a lower side portion of the horizontal girder 5 excluding an attachment portion to the portal 4. And third curtains 18a and 18b are arranged on the boat 17 so that one end thereof is connected to the lower end of the second curtain 15.

Therefore, the roof covering the bridge type crane 1 and the first
And the third curtains 18a and 18b for covering the hatch of the ship 11, the second curtain 15 and the second curtain 15, and a rainproof section required for cargo handling can be formed. Since the rainproof compartment can be easily moved to a predetermined place and formed, there is an effect that the cargo handling efficiency can be significantly improved by extremely simple means.
