Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unloading apparatus, and more particularly to an unloading apparatus used when a material such as a finishing agent is taken in or removed from the outside in the building construction.

[0002]

2. Description of the Related Art Conventionally, in building construction, in order to take in materials 2 such as tiles and finishing agents from the outside to the second floor or above, for example, the fifth floor, inside the building 1, an elevator (not shown) inside the building 1 is used. The temporary material 3 which is either used or which is projected from the 5th floor to the outside of the building 1 as shown in FIG. 5 and the free end of which is fixed to the ceiling of the 5th floor of the building 1 via a wire rope or the like is provided. The material 2 was placed on the 3 by the ground crane 4, or the placed material 2 was taken out.

[0003]

However, since it is not possible to take in many materials at the same time only by taking in the materials 2 by the elevator, work efficiency is poor, and it is troublesome and time-consuming to provide the temporary materials 3 outside the building. Therefore, work on the temporary material 3 may be dangerous.

Further, as shown in FIG. 6, an obstacle 5 such as an outer wall
If there is such a problem, there is a drawback that the temporary material 3 cannot be installed outside the building 1.

The present invention is intended to eliminate the above drawbacks.

DISCLOSURE OF THE INVENTION An unloading device of the present invention is a horizontal unloading body, a means for lifting the unloading body, a means for connecting one end of the unloading body to a load, and a horizontal balance of the unloading body. The balance weight is fixed on the unloading body in a positionally variable manner to maintain the balance weight.

Further, the unloading device of the present invention comprises a horizontal unloading body, a means for lifting the unloading body, a means for connecting one end of the unloading body to a load, and a counterweight fixed to the other end of the unloading body. And a balance weight fixed on the unloading body in a variable position so as to maintain the horizontal balance of the unloading body.

The load can be placed on the unloading body.

The means for hoisting the unloading body includes a main wire whose lower end is connected to one point of the unloading body and whose upper end is connected to a crane, and whose lower end is connected to a point different from the above-mentioned one point of the unloading body. Comprises an auxiliary wire connected to the crane.

The position changing means of the balance weight is
It comprises means for detecting the inclination of the unloading body and mechanical or hydraulic means controlled by this means.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

In the present invention, as shown in FIG. 1, the main wire 7a is provided at two different locations in the middle of the rod-shaped unloading body 6.
And the lower ends of the auxiliary wires 7b are attached respectively, and the upper ends of the two wires 7a and 7b are attached to the hooks of the crane 4, respectively. In addition, the material lifting wire 8 is hung from the inner end of the unloading body 6 and the fixed counterweight 9 is fixed to the outer end.

A balance weight 10 is placed on the unloading body 6 so as to be movable left and right.

Since the unloading device of the present invention has the above-mentioned structure, when the material 2 inside the building 1 is carried outside, the unloading main body 6 is moved to the building 1 by the ground crane 4 as shown in FIG. However, in this case, no material is hung on the wire 8 for hoisting material at the inner end of the unloading body 6, and therefore no weight is applied. However, since there is a fixed counterweight 9 at the outer end of the unloading body 6, in FIG. 1, the balance weight 10 is moved to the left so as to balance the weights of the left side and the right side of the unloading body 6. The unloading body 6
Fixed to.

Next, as shown in FIG. 2, the unloading body 6 is hoisted to a desired floor in order to hoist the material 2 in the building 1, and its inner end is kept in the building 1 while avoiding the obstacle 5. It is inserted and positioned on the upper part of the material 2, and this material 2 is attached to the wire 8 for lifting the material.

In this state, the crane 4 raises the unloading main body 6, but in this case, since the weight is added to the left side of the unloading main body 6, the balance weight 10 is moved to the right and the left and right weights are moved. After balancing, the balance weight 10 is fixed to the unloading body 6, the unloading body 6 is raised, and then the material 2 is guided to the outside of the building 1 and hung.

Further, when the material 2 is taken into the building 1, the method reverse to the above is used. That is, while the material 2 is suspended by the wire 8, the balance weight 10 is moved to the right so that the left and right weights of the unloading body 6 are balanced, and after fixing, the unloading body 6 is raised.
After the material 2 is detached and placed in the building 1, the unloading body 6 is placed.
The balance weight 10 is moved to the left so that the left and right weight balance of the FIG. 3 is an explanatory view when the building 1 has no obstacle 5.

In another embodiment of the present invention, the balance weight 10 is used to balance the unloading body 6 without fixing a fixed counterweight to the outer end of the unloading body 6.

In this embodiment, the balance weight is positioned on the right side of the unloading body 6 when suspending the material, and when the material is not suspended, the balance weight is positioned on the left side of this. Become.

In another embodiment of the present invention, the lengths of the two wires 7a and 7b may be equal to each other as shown in FIG.

The unloading body 6 may have a flat plate shape so that the material 2 can be placed thereon.

In addition to moving the balance weight 10 manually, the weight of the material 2 is detected, or the inclination of the unloading body 6 is detected by a level meter, and mechanical means or hydraulic type is used according to the result. It can be done by means.

[0023]

As described above, according to the unloading apparatus of the present invention, it is not necessary to project the temporary material for lifting the material outside the building when the material is taken in the building or taken out of the building. , Which is extremely advantageous in terms of the number of days for manufacturing, cost, and safety at the time of dismantling.
