Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile unloading gantry used for transporting luggage such as building materials to each floor in the construction of high-rise buildings.

[0002]

2. Description of the Related Art Conventionally, in the construction of a high-rise building, when a building material is transported to each floor, the building material is hoisted by a crane or the like. There is a risk of injuring people passing by outside the building.

Therefore, as shown in FIGS. 3 and 4, there is a method of hoisting the building material 3 through the openings 1a, 2a, ... Formed in the floors 1, 2 ,.
Specifically, the opening 1 is provided on the floor 1 and the floor 2.
A movable cargo unloading gantry 4 for opening and closing a and 2a is provided. Then, for example, in order to transport the building material 3 on the floor 1, the building material 3 is lifted via the rope 5 by a crane (not shown) with the openings 1a and 2a opened, and is lifted to just above the floor 1. In this state, the movable loading platform 4 is moved in the direction of the arrow to close the opening 1a,
After that, the building material 3 is lowered and placed on the movable cargo unloading gantry 4.

Next, the building material 3 thus placed on the movable cargo unloading gantry 4 is lowered onto the floor 1 for use.

[0005]

However, in such a conventional one, since there is a step between the upper surface of the movable cargo unloading gantry 4 and the upper surface of the floor 1, the movable cargo unloading gantry 4 has a step. A heavy building material 3 placed on the floor 1
It was hard to get it down.

[0006] Therefore, an object of the present invention is to provide a mobile unloading gantry capable of easily moving loads such as building materials from the mobile unloading gantry to the floor.

[0007]

In order to solve the above problems, the present invention is arranged so as to be movable in an opening formed in a floor of a building, and receives a suspended load through the opening. In the loading platform, a movable body is provided, which has a leg portion movably arranged at a peripheral portion of the opening, and a cradle on which a load is integrally placed on the leg portion,
The cradle is characterized in that the cradle is inserted into the opening so that the upper surface thereof is set to be substantially the same as the upper surface of the floor.

[0008]

[Operation] According to such means, if the upper surface of the cradle of the mobile unloading gantry is set at substantially the same height as the upper surface of the floor, the load placed on the cradle can be set as in the conventional case. It is not necessary to unload it from the movable cargo platform to the floor, and it can be easily moved to the floor.

[0009]

EXAMPLES The present invention will be described below based on examples.

1 and 2 are views showing an embodiment of the present invention. The same or equivalent members as the conventional ones will be described with the same reference numerals.

First, the structure will be described. A rectangular opening 31a is formed on the floor 31 of each floor of a high-rise building, and the building material 3 is received as a luggage suspended through the opening 31a in the opening 31a. Movable pickup yard 3
2 are movably arranged.

[0012] Specifically, this movable loading platform 32
Is composed of a total of three rectangular moving bodies 33, 34, and 35 connected in parallel, and is formed to have a size approximately half that of the opening 31a.

These moving bodies 33, 34, 35 are rectangular in shape, and leg portions 33b, 34b, 35b are projected from the four corners of the pedestals 33a, 34a, 35a. The legs 33b, 34b, 35b have rollers 33c, 34 rolling on the peripheral edge of the floor opening 31a, respectively.
c, 35c are provided.

The moving bodies 33, 34 and 35 are
The connecting member 50 allows detachable connection.

The pedestals 33a, 34a, 35a of the moving bodies 33, 34, 35 are inserted into the openings 11a, and the upper surfaces of the pedestals 33a, 34a, 34a are, as shown in FIG. The height is set to be substantially the same as the upper surface of the floor 31.

Further, on the floor 31, there is an opening 31a.
A fixed handrail 36 is provided in a U-shape around, and a moving handrail 37 that opens and closes the open portion of the U-shape is provided so as to be rotatable in the arrow direction in FIG.

Next, the mobile unloading gantry 32 having the above structure.
The operation of will be described.

In such a structure, the building material is received on the movable cargo unloading gantry 32 at the position shown in FIG. Then, after moving the movable unloading gantry 32 in the direction of arrow A, the building material can be moved onto the floor 31 from the gantry 32 via the side opened by the moving handrail 37.

Thus, the upper surface of the floor 31 and the pedestal 33
By making the upper surfaces of a ... substantially flush with each other, the building material 3 can be easily moved from the movable load collecting gantry 32 to the floor 31, so that workability is better than before.

[0020]

As described above, according to the present invention, the upper surface of the pedestal of the movable cargo unloading gantry is set at substantially the same height as the upper surface of the floor. There is a practically useful effect that the loaded luggage can be easily moved onto the floor without the need to unload it from the movable pickup platform on the floor as in the conventional case.
