[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for extending a monorail for transportation for traveling a trolley for transporting a transported object.

[0002]

[Prior art]

 Conventionally, the transport of heavy objects has been carried out using traveling cranes that travel on rails, trolleys that travel on monorails for transportation, and the like. In addition, the traveling crane and the trolley may be used together to convey the conveyed object. When a traveling crane and a trolley are used together, for example, the transported object transported by the traveling crane must be unloaded halfway, then the transport means must be changed to a trolley, and the transported object must be transported again. When carrying out the transfer of transferred items in this way, care must be taken in the position where the transferred items are lowered. That is, it is necessary to lift the transported article by the trolley which is the next transportation means at a position just above the transported article lowered from the traveling crane. This is because when a heavy load is to be lifted from an oblique direction rather than directly above, a tensile force from an oblique direction acts on the rail of the trolley, and the load is pendulum-moved in the air, which is extremely dangerous. That's why.

In order to avoid such a danger, it is necessary to planarly overlap the movable range of the traveling crane and the monorail on which the trolley travels. If these can be overlapped in a plane, the traveling crane can be evacuated after lowering the transported object, and then the trolley can be moved to directly above the transported object and lifted. In this way, in order to overlap the movable range of the traveling crane and the installation portion of the monorail in a plane, the height of the traveling crane and the height of the monorail of the trolley must be different.

[0004]

[Problems to be solved by the device]

 However, when the traveling crane and the trolley are installed indoors, it may not be possible to design the traveling crane and the trolley to travel at different heights due to the height limitation of the building. In such a case, it is not possible to transfer the transferred goods from the traveling crane to the trolley.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide another transfer means used at positions having substantially the same height. It is an object of the present invention to provide an extension structure of a monorail for transportation, which enables remounting of transported objects.

[0006]
