DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material transporting device for openings which is suitable for transporting various materials, for example, when constructing a basement floor of a building.

[0002]

2. Description of the Related Art Generally, when carrying various materials when constructing a basement floor of a building or the like, the basement floor frame is surrounded by the ground and there is no space for installing a material transporting device around the basement floor. There is an opening on the floor for carrying materials. At this time, when there are a plurality of basement floors, the opening is formed at the same position on each floor, and a space continuous in the vertical direction is provided. Then, the material is dropped from the ground to a predetermined floor through the opening of each floor by a crane or the like installed on the ground.

On the floor where the materials are received, it is naturally dangerous to embark on the opening and receive the materials,
A temporary cargo receiving stage that closes the opening on the floor is installed. This load receiving stage is provided with a slide mechanism and a flip-up mechanism so as not to always close the opening, and closes the opening only when necessary.

[0004] The material transfer device for opening comprising such a crane or the like and a load receiving stage provided with a slide mechanism and a flip-up mechanism is not limited to a case where the material is carried from the ground to the basement floor. It is also used when transferring materials to lower floors and unloading from basement floors to the ground. In addition, not only the basement floor but also the same configuration is used when there is no space for arranging a crane truck or the like around the building floor or the like.

[0005]

However, the above-described conventional material transfer device for openings has the following problems. First, since the receiving stage must be provided for each floor, there is a problem that not only the operation of the receiving stage is troublesome, but also that the temporary stage is too expensive. Also, for example, when lowering materials from the middle basement floor to a lower floor, it is conceivable to install a small crane or the like on the basement middle floor and use it. In some cases, it is difficult to secure the margin, and it takes a lot of time to install, replace, and remove cranes.

The present invention has been made in consideration of the above points, and has as its object to provide a material transporting device for openings that can transport materials easily and at low cost.

[0007]

The invention according to claim 1 is
An apparatus for transporting materials by moving up and down through an opening formed in a floor or the like, comprising a frame main body, an elevating mechanism for elevating and lowering the frame main body, and extending or rotating laterally from the frame main body. With movable legs provided,

In such a material transfer device for opening, the material is held by the holding mechanism, and the movable leg and the movable beam are moved up and down through the opening with the movable leg contracted. When the vehicle arrives at the predetermined floor, the movable leg is extended and is supported on a floor or a beam around the opening. Further, the movable beam is extended, and the material held by the holding mechanism is moved above the floor around the opening to unload the material.

According to a second aspect of the present invention, in the material transporting device for an opening according to the first aspect, the movable leg is supported by a temporary bracket provided near the opening when the movable leg is extended. It is characterized by being.

According to a third aspect of the present invention, in the material transporting device for an opening according to the first aspect, the movable leg is supported on a floor around the opening when the movable leg is extended. Features.
