Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rain-weather cargo handling device for a pneumatics unloader that enables cargo handling operations in rainy weather for a pneumatics unloader that vacuum-suctions powder and granules from a ship's hold in bulk and unloads them.

Conventionally, bulk powder and granules are unloaded by opening the hatch cover and moving the suction port of the pneumatic unloader to various locations in the hatch. Powder and granular materials, especially grains, are susceptible to various problems such as rotting, residue, and blockage when wet. Therefore, in case of rain, cargo handling operations are stopped and the hatch cover is closed.
We are now waiting for the rain to pass.

Recently, consideration has been given to modifying the hatch cover and making the opening smaller so that work can be done even in the rain. However, these methods mainly involve modifying the ship's hatch cover, and have drawbacks such as the need for specialized ships.

The purpose of the present invention is to eliminate the drawbacks of the prior art,
It is a rain-weather cargo-handling device for a pneumatic unloader that is installed on a ship but not permanently installed, and is particularly suitable for cargo-handling work on large ships, and is capable of carrying out cargo handling operations even in rainy weather. To provide a rainy weather cargo handling device that can smoothly operate and has excellent durability.

The present invention provides a cart that can run on a hatch cover rail laid along a hatch opening, an awning material connected to the front and rear of the cart and covering the hatch opening, and both ends of the awning material. a side frame having wheels that are coupled with pins and run on the hatch cover rails in order to support the trolley and expand and contract the awning material in a bellows shape in response to the trolley; A step-like sliding roof that is slidably attached using an upright cover as a guide, and a drum-shaped guide that is provided on the top plate of the sliding roof and guides the vertical movement of a suction pipe that passes through the top plate. Since it is composed of rollers, the suction pipe of the pneumatic unloader can move smoothly in three dimensions, and the hatch cover rail is used to guide the movement, so it is stably supported and can be used to move the ship's hatch cover. It is possible to perform work in rainy weather without modifying the equipment.

FIG. 1 is a side view of an embodiment of a rain-weather cargo handling device for a pneumatic unloader according to the present invention, FIG. 2 is a plan view, and FIG. 3 is a sectional view taken along the - arrow in FIG. 2.

The tent material 1 is tied to a plurality of side frames 2 on both sides, and the side frames 2 are connected to pins 3.
They are rotatably joined to each other via a , and a trolley 4 is interposed in the center. As the side frame 2 expands and contracts, the tent material 1 also expands and contracts. The expansion and contraction can be performed with a small force because the wheel 7, which is rotatably fixed to the pin 3 on the upper surface of the rail 6 for opening and closing the ship's hatch cover laid on the ship's hatch 5, rolls. For example, it is possible to simply move the suction section of the pneumatic unloader. As shown in Fig. 1, two awning materials 1 are fixed to a cart 4 equipped with an input port 8 of the suction section, and if the cart 4 is strong enough, it can be moved smoothly without skewing. . With this combination, the suction section of the pneumatic unloader can be moved almost freely within the hatch in the direction of expansion and contraction of the awning material 1.
The awning material 1 is sloped so that rainwater is not always stored, and the load applied to the awning material 1 is reduced.

In addition, roofs 9A, 9B, 9 provided on the trolley 4
C, 9D and 9E are FRP as shown in Figure 3.
The sliding roof is made of a lightweight structural material such as, for example, and has an opening for the input port 8 of the suction section in the center. It is rotatably fixed to a pin 13 attached to. Each roof may be provided with rollers to facilitate movement. The raised part of the top roof 9A is a cover 14 fixed to the trolley 4.
Prevent by. The rainy weather cargo handling device for a pneumatic unloader according to the present invention is configured so that the suction section for bulk powder and granules can be freely moved not only in the direction of expansion and contraction of the awning, but also in the direction perpendicular to the direction of expansion and contraction of the awning. Even in rainy weather, cargo handling operations can be carried out almost in the same way as in sunny weather, and since the hold is covered by the awning material 1 and the roof 9 attached to the loading port movable trolley 4, rain hardly enters. Furthermore, this device has a structure that moves on the rails 6 of the hatch cover, and the entire device can be easily attached and detached using a crane or the like. If it is placed near the pneumatic unloader after being removed, it can be installed immediately even when another ship comes on board and it rains.

As explained above, according to the present invention, the awning material that covers the opening of the hatch is supported by the side frames on both sides and performs a bellows movement, so that the awning material is less likely to bend and prevent rainwater from accumulating. This can be prevented, and the sliding roof of the truck allows the suction pipe to move smoothly. In particular, the sliding roof structure reliably prevents rainwater from entering through the roof, and the structure has extremely high durability during traversing. Furthermore, since the suction pipe of the unloader is guided by a drum-shaped guide roller when going up and down, the sliding roof and the tent material are not bent during going up and down, which greatly contributes to improving work efficiency.
