Abstract

PURPOSE:To improve workability and safety without necessitating projectingly- installation of a temporary construction member for lifting a material outside a building when the material is taken inside/outside the building by movably supporting a horizontal load lifting main body and providing a supporting stand capable of being fixed on the load lifting main body. CONSTITUTION:In order to lift a material 2 stayed in a building 1, a supporting stand 8 is lifted together with a load lifting main body 6 to the specific floor, and the inner end is inserted into the building 1 while avoiding an obstacle 5, so as to be positioned above the material 2, and this material 2 is attached to a material lifting wire 9. When the supporting body 8 is raised together with the load lifting main body 6 by a crane 4 with this state, the load lifting main body 6 is moved rightward in relation to the supporting body 8, and the weights of the right and left are balanced with each other, after that, the load lifting main body 6 is fixed to the supporting stand 8, so as to raise the supporting stand 8 together with the load lifting main body 6, next, the material 2 is guided outside the building 1 so as to be suspended. Moreover, when the material 2 is taken inside the building 1, the method opposite to the above- mentioned one is used.

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, an elevator (not shown) inside the building 1 has been used in order to take in materials 2 such as tiles and finishing materials from the outside to the second floor and above, for example, the fifth floor, inside the building 1. Temporary material 3 which is used or fixed to the ceiling of the 5th floor of the building 1 via wire rope or the like by projecting it from the 5th floor to the outside of the building 1 as shown in FIG.
A ground crane 4 is provided on the temporary material 3 to provide the material 2
Or the material 2 on which it was placed 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. 5, 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.

[0006]

The unloading device of the present invention comprises a horizontal unloading body and a movably supporting the unloading body.
It comprises a support base that can be fixed to the unloading body, means for lifting the support base, and means for connecting one end of the unloading body to the load.

Further, the unloading device of the present invention comprises a horizontal unloading body, a support table which is movably supported by the unloading body and can be fixed to the unloading body, a means for lifting the support table, and the unloading body. And a counterweight fixed to the other end of the unloading body.

The load can be placed on the unloading body.

Means for hoisting the support base include a wire whose lower end is connected to one point of the support base and whose upper end is connected to a crane, and whose lower end is connected to a point different from the one point of the support base and whose upper end is connected. A wire connected to the crane.

The means for changing the position of the unloading body 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, a rod-shaped unloading main body 6 is movably supported by a support base 8 via a ball bearing or the like, and a main wire 7a and a main wire 7a are provided at two different positions of the support base 8. 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 9 is suspended from the inner end of the unloading body 6, and the fixed counterweight 10 is fixed to the outer end.

Since the unloading apparatus of the present invention has the above-mentioned structure, when the material 2 inside the building 1 is carried out to the outside, as shown in FIG. 8 is hoisted along the outer wall of the building 1, but in this case, no material is hung on the wire 9 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 10 at the outer end of the unloading body 6, in FIG. 1, the unloading body is relatively moved to the support base 8 so as to balance the left and right weights of the unloading body 6. 6 is moved to the left and fixed to the support base 8.

Next, as shown in FIG. 2, in order to lift the material 2 in the building 1, the support base 8 is lifted up to the desired floor together with the unloading body 6 while avoiding the obstacle 5 at its inner end. The material 2 is inserted into the building 1, positioned above the material 2, and the material 2 is attached to the wire 9 for lifting the material.

In this state, the crane 4 raises the supporting base 8 together with 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 above-mentioned supporting base 8 is relatively moved. After moving the unloading body 6 to the right to balance the left and right weights, the unloading body 6 is fixed to the support base 8, and the unloading body 6 and the support base 8 are fixed.
, And then guide the material 2 outside the building 1 and hang it.

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 9, the unloading body 6 is moved to the right so that the left and right weights of the unloading body 6 are balanced and fixed, and then the support base 8 is raised together with the unloading body 6. After the material 2 is detached and placed in the building 1, the unloading body 6 is moved to the left so that the left and right weights of the unloading body 6 are balanced. FIG. 3 is an explanatory view when the building 1 has no obstacle 5.

The unloading body 6 may be in the form of a flat plate so that the material 2 can be placed thereon.

In addition to moving the unloading body 6 manually, the weight of the material 2 is detected, or the inclination of the unloading body 6 or the support base is detected by a level meter, and a mechanical means for responding to this result. Alternatively, it can be done by hydraulic means.

[0019]

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.
