Abstract

PURPOSE:To set and remove frames simply and rapidly by the operation of a rope by inserting the rope furnished with bar bodies to be fitted in joint parts through a folding frame connecting several gate-shaped frames in parallel to support a tent. CONSTITUTION:A tent 28 is stretched on several gate-shaped wheeled frames 30 in parallel, and these gate-shaped frames 30 are mutually connected by a folding connection frame 36 via joint parts 40. Through this connection frame 36, a rope 48 is inserted, and on this rope 48, frame-stiffening bar bodies to be fitted in joint parts 40 of the connection frame 36 are fixed to be moved in one body with the rope 48. Folding frames 40 are extended, and after parallel gate-shaped frames 30 are set on the opening of a hatch, the rope 48 is pulled in one direction. This construction permits to fit bar bodies in joint parts 40, ensure the setting of gate-shaped frames 30, fix and remove them rapidly and simply.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rain cover for unloader cargo handling in rainy weather, which is suitable for unloading powder and granular materials from a hold of a ship in rainy weather.

[Background technology]

Generally, when unloading bulk powder and granular materials from a ship's hold, the nozzle cover is opened and the suction port of the unloader is inserted directly into the cargo hold. .

Work is often stopped due to the need to avoid blockages.

However, in recent years, due to demands such as improving the operational efficiency of ships, it is desirable to be able to land even in rainy weather, and it is considered to cover the hold with conventionally known awning devices, but the area of the hold that needs to be covered is vast. As a result, work efficiency related to installation, etc. is poor, and there are practical difficulties.

[Purpose of the invention]

An object of the present invention is to provide a cover for unloader I17 cargo handling that is lightweight, has high strength, and can be installed easily and quickly.

[Summary of the invention]

In the rain cover for unloader cargo handling in rainy weather according to the present invention, the awning is installed on a plurality of wheeled portal frames that can run along both sides of the cargo hold, and these portal frames are connected to each other by a collapsible connecting frame. At the same time, insert a rope with a rod into the connecting frame, move the rope under the condition that the connecting frame is straight when the portal frame is placed along the entire length of the hold, and insert the rod into the joint of the connecting frame. The frame is interposed to maintain a rigid state. That is, the awning can be quickly expanded or contracted by moving the portal frame, and the expanded state can be reliably maintained by the easy pulling and movement of the rope.

[Embodiments of the invention]

Hereinafter, two embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an application example of the cover for rainy weather cargo handling of an unloader according to this embodiment. That is, the nozzle 14 of the transport pipe 12 extending from the pneumatic unloader 10 installed on land is inserted into the hold 16 through its opening, that is, the hatch 1.
Introduced via 8.

The granular material 20 in the hold 16 is unloaded via the transport pipe 12. The double-strength bar 22 of the unloader for cargo handling in rainy weather is suspended and installed on the hatch 18 using the boom 24 and hoist 26 of the pneumatic unloader IO.

As shown in FIGS. 2 and 3, in the copper cover 22 for rainy weather cargo handling of the unloader according to the present embodiment, each gate-shaped frame 30 on which the awning 28 with the transport pipe insertion hole 27 is laid is attached to both sides of the hatch 18. A pedestal 32 with a pair of wheels 32 located at
and a roof frame 34 built over its upper end. The interframe frames 30 are arranged in parallel in the longitudinal direction (horizontal direction in the figure) of the hold 16, and are movable so as to increase or decrease the distance between them. Each roof frame l,
34 is in the shape of a circular tube, and the central position is connected to a connecting frame l,
36.

As shown in FIGS. 4 and 5, this connecting frame 36 has a pair of tube bodies 4 connected to both sides of each roof frame 34 via hinges 38 so as to be foldable up and down.
0 are further connected to each other by separate hinges 42 at their tips so that they can be folded in opposite directions. Note that the axial center of each tube body 40 intersects with the axial center of the roof plate 34. Each tube body 4o is open at both ends and communicates with through holes 44 formed on both sides of the roof frame 34.

Furthermore, the connecting frame 36 includes a flexible rope.

For example, a wire rope 46 is inserted through the entire length of the roof frame 34 and is movable in the axial direction of the connecting frame 36 via two end operating portions 48 that are exposed.

The wire rope 46 is connected to a collapsible connecting portion between the tube bodies 40, that is, a joint portion 4oAKI&'
0 is the number and spacing corresponding to the joint portion 40A, and is attached so as to be movable integrally with the wire rope 46. Note that the wire rope 46 can be immovably fixed by a suitable locking means.

In a cargo handling state where a cover is not required, the rod 50 is moved to a position where it is removed from the joint 40'A of the connecting frame 36 via the operation parts 48 at both ends of the wire rope 46, and the connecting frame 36 is brought into the folded state ( In the state shown in FIG. 5), the hatch 18 may be moved to one side and placed on standby.

In case of rain, each portal frame 30 is moved over the entire length of the no-tsuchi 18 (the state shown in FIGS. 2 and 3), and when each tube body 40 of the connecting frame 36 is straight, the wire rope is 46, the rod 50 is placed in the joint 40A (the state shown in FIG. 4). By doing so, the joint portion 40A will not be folded, and the connecting frame 36
becomes rigid, and the awning 28 maintains the state in which the awning 18 is covered. The transport pipe 12 may be introduced into the hold 16 through the necessary transport pipe insertion hole 27 of the awning 28.

Note that by applying a horizontal tensile force to the wire rope 46, each tube body 40 can be automatically straightened.

According to the unloader for cargo handling in rainy weather according to the present embodiment, the structure is such that the wire rope 46 is inserted through the hollow connection frame 36, so that it is lightweight.

(The body 50 is fitted into the joint portion 40A and the connecting frame 1.
36 in a rigid state, the structural strength is sufficiently high and the installation state is stable.

Moreover, since the cover can be opened and closed only by moving the portal frame 30 and the wire rope 46 and folding the connecting frame 36, the two operations can be performed easily and quickly. In particular, as shown in the figure, each tube body 40 constituting the connecting frame is connected to the roof frame 34 so that it can be folded in the direction in which it hangs under its own weight. It can be done without any work.

Note that the number and arrangement of the connecting frames 36 are not limited to those in the embodiment described above, and a plurality of connecting frames 36 may be used, and they may be attached at appropriate positions such as at both ends of the roof frame 34. Furthermore, the connecting rail l- may have a structure in which only the fitting portion of the rod is tubular. The wire rope 46 is not passed through the roof frame roller 4,
Of course, the detailed configuration can be modified as appropriate without departing from the gist, such as by extending the upper part.

〔Effect of the invention〕

As described above, according to the present invention, it can be installed easily and quickly even in places with poor footing or in places with a vast coverage area, and can be installed in places where an unloader is used as it is lightweight and has high strength.
