【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, reference numeral 1 denotes a bridge-type crane as a cargo handling facility provided in, for example, a port facility, and a gate-type traveling frame 4 which is freely movable on a pair of traveling rails 3 arranged along the quay 2. A crane girder 5 held on the upper horizontal girder portion 4a of the traveling frame 4 in a direction orthogonal to the upper horizontal girder portion 4a, and a trolley cart 6 movably provided on the crane girder 5. The trolley truck 6 is provided with a hoist 7 and the bridge crane 1 is equipped with a rain cover device 10 according to the present invention.

The rain cover device 10 will be described below. The rainproof cover device 10 is provided inside the traveling frame 4 and is provided with a support frame (also referred to as a support frame) 11 provided so as to be able to travel on the traveling rail 3 and a crane mounted on the support frame 11. It is composed of a movable frame (also referred to as a slide frame) 12 that is movably installed along the girder 5.

The support frame 11 has a width and a length which are substantially the same as the width and length of the traveling frame 4, and the lower and left and right front and rear positions of the supporting frame 11 allow free traveling on the traveling rail 3. A traveling device 14 having wheels 13 is provided, and the traveling device 14 is controlled to travel in synchronization with the support frame 11.

Guide rails 15 are provided on the upper and lower surfaces of the moving frame 12 along the crane girder 5, and a guide rail 15 is movably guided to the support frame 11 side. A roller 16 is provided, and a moving device 17 for moving the moving frame 12 along the crane girder 5 is provided.

As shown in FIGS. 5 and 6, the moving device 17 includes a winch device 21 provided on the side of the support frame 11 and one end of which is pulled out from a winding drum 22 of the winch device 21 and The first guide pulley 23 provided on the support frame 11 and the second guide pulley 24 provided on one end of the moving frame 12 are wound one after another, and then the first rope fixed to the support frame 11 side. A body (for example, a wire rope) 25, and a third guide pulley 26 and a moving frame 12 whose one end is similarly pulled out from the winding drum 22 of the winch device 21 and whose other end is provided on the support frame 11. After the fourth guide pulley 27 provided at the end is sequentially wound, it is composed of a second rope (eg, wire rope) 28 fixed to the supporting frame 11 side. Of course, the winch device 21 is provided with an electric motor 29 for rotating the winding drum 22.

Therefore, by rotating the winding drum 22 of the winch device 21, the moving frame 12 can be reciprocated along the crane girder 5. The moving devices 17 are arranged on both sides of the moving frame 12, and in some cases, the moving device 17 may be provided on only one side.

Further, the left and right outer wall surfaces 11a, 12a and the upper wall surfaces 11b, 12b of the support frame 11 and the moving frame 12 are provided with exterior materials 31 and 32 for preventing raindrops, and each frame 11 , 12 at the central portions of the exterior materials 31, 32 provided on the upper wall surfaces 11b, 12b of the crane girder 5 for suspending the hanging hooks 8 from the hoisting machine 7 ( Openings 31a and 32a for inserting the (hanging wire) 9 are formed.

A large number of air injection nozzles 33 are arranged at predetermined intervals at both side edges of the insertion opening 32a provided on the moving frame 12 side in order to prevent raindrops from entering. Thus, the air curtain can be formed.

In the above configuration, when unloading from the ship A in rainy weather, after the traveling frame 4 has traveled to a position corresponding to the ship A, the moving frame 12 is projected from the quay 2 onto the ship A, and the hanging hook is used. The load B may be hoisted by the hoisting machine 7 via 8 and conveyed to a predetermined place. Then, during this operation, air is ejected from the air ejection nozzles 33 provided on both side edges of the insertion opening 32a on the side of the moving frame 12 to form an air curtain, and raindrops inside the moving frame 12 are formed. Is prevented from entering.

As described above, the hanging hook 8 is always covered with the exterior materials 31 and 32, and the insertion opening 32a of the hanging rope 9 suspended from the hoist 7 is also exposed to the outside by the air curtain. Since it is in the shut-off state, the raindrops do not splash on the baggage B, and therefore, the unloading work can be performed regardless of the weather.

By the way, in the above-described first embodiment, the insertion opening 32a of the hanging rope 9 is blocked by the air curtain. However, as shown in FIG. 7, for example, as shown in FIG. Brushes 41 may be attached to both side edges of the common opening 32a to prevent raindrops from entering.

Further, as shown in FIGS. 8 and 9, a bellows-type cover 51 may be provided over the entire length of the insertion opening 32 a of the moving frame 12. Of course, a tubular body 52 for inserting the hanging rope 9 is provided in an intermediate portion of the cover body 51.

In order to monitor the suspended state inside the moving frame 12, the external material 32 that covers at least the upper wall surface 12b of the moving frame 12 among the frames 11 and 12 is made transparent. Alternatively, a surveillance camera is provided inside the moving frame 12.

Next, a second embodiment of the present invention will be described with reference to FIGS. 10 and 11. In the first embodiment described above, the one in which the opening for insertion of the moving frame is covered has been described, but in the second embodiment, only the upper part of the luggage is covered. .

That is, as shown in FIGS. 10 and 11, guide rails 61 are arranged on both side edges of the insertion opening 32 a of the moving frame 12, and the guide rails 61 are guided by guide wheels 62. The movable cover 63 is arranged to be movable and provided with a hole 63a for inserting the hanging rope 9 in the center. Of course, the size of the movable cover 63 is set so that the luggage B is not exposed to raindrops.

As described above, according to the configuration of the above-described embodiment, the rain cover device can be easily attached to the existing bridge-type crane, so that it can be easily converted into an all-weather unloading facility. .

By the way, in each of the above-mentioned embodiments, the exterior material is provided over almost the whole of the support frame and the moving frame. However, for example, when a load is hung, at least in a range where raindrops are not applied to the load. Alternatively, an exterior material may be provided.

[0024]

[Effect of device]

 As described above, according to the configuration of the present invention, the moving frame is provided with the exterior material for covering the hanging hook portion from the hoisting machine provided in the crane girder, and the raindrop intrusion is made through the insertion opening of the hanging rope. Since either an air curtain for prevention, a brush, a bellows type cover or a movable type cover is provided, it is possible to prevent raindrops from falling on the luggage, and therefore it is possible to carry out the unloading work even in the rain. It is possible to prevent the unloading schedule from becoming out of order.
