BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compressed air heavy weight moving apparatus and method for floating and moving a heavy weight by using compressed air.

[0002]

2. Description of the Related Art Conventionally, when a heavy object is installed on a site such as a factory, the heavy object is moved by using a crane or a trolley for installation of the heavy object. However, when using a crane to move heavy objects inside the building, it is necessary to remove the roof of the building when using the crane, and when moving heavy objects using a moving carriage, the floor of the building must be removed. When the surface is uneven or the floor of the building is soft, it is very difficult to carry. In particular, it is difficult to move an object such as glass in which the heavy object itself is easily broken by vibration or the like. Also, when a heavy object is moved using a roller, there are the same problems as in the case of a moving carriage. Furthermore, when a heavy load is moved using such a moving carriage or roller, frictional resistance is generated between the heavy load and the ground, which increases the power or energy required to move the heavy load. . By the way, in order to eliminate the frictional resistance generated between the ground and the ground, there is a method using a hovercraft in which a heavy object is floated in the air and conveyed. However, the hovercraft has a problem in that it is difficult to adjust the amount of air blown out, the means for the adjustment is complicated, and the hovercraft becomes large.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, an object of the present invention is to use a compressed air which has a simple structure and which has no vibration during the transportation of the heavy object and can easily move the heavy object with a small energy. A heavy load moving device and method thereof.

[0004]

The above object is to provide a heavy-weight moving device, a box-shaped pedestal, a flexible sheet laid on the pedestal and the floor, and means for supplying compressed air to the pedestal. When the compressed air is supplied to the pedestal and the weight of the pedestal is pressurized to an air pressure commensurate with the weight of the heavy object to float the heavy object, the air of the pedestal generated between the pedestal and the floor surface. The sheet automatically adjusts the size of the opening width of the blowing surface,
This is achieved by floating and moving a heavy object while keeping the opening between the air blowing surface of the pedestal and the seat constant.

[0005]

According to the present invention, since the flexible sheet used in the lower portion of the box-shaped pedestal keeps the opening of the air blowing surface of the pedestal constant, even if the floor surface is uneven or the floor surface is soft. ,
The entire pedestal can be levitated and heavy objects can be vibrated without vibration.
It can be transported with a small amount of energy and easily. In addition, since the pedestal for loading the heavy object has a box-shaped structure, the heavy object moving device can have a simple structure as a whole.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention. In FIG.
1 is a heavy object to be transported, 2 is a box-shaped pedestal in which the lower part for loading the heavy object 1 is open, 3 is a flexible resin sheet,
Reference numeral 4 denotes a nozzle provided on the side of the pedestal 2, 5 denotes a valve provided at the tip of the nozzle 3, and 6 denotes a lifting hook. In the present embodiment, in order to move the heavy load 1, a flexible resin sheet 3 is laid on a moving path (not shown) of the heavy load 1,
A box-shaped pedestal 2 having an open lower portion is placed on the resin sheet 3, and the heavy object 1 is loaded on the pedestal 2. In this state, compressed air is supplied to the nozzle 4 and the valve 5 is opened to adjust the air supply, and the compressed air is sent to the lower portion of the pedestal 2 to bring the inside of the pedestal 2 into a pressurized state. When this pressurized state reaches a pressure commensurate with the weight of the heavy object 1, compressed air is jetted from between the lower part of the pedestal 2 and the resin sheet in the peripheral part of the lower part. Along with this jet of compressed air, the entire pedestal 2 floats up from the floor together with the heavy object 1 and becomes in a floating state. When the truck 2 is pushed (force is applied) in the direction in which the heavy object 1 is to be moved in this floating state, the heavy object 1 of, for example, 1 ton or more easily moves. After moving the heavy object 1 to a predetermined installation place, in order to install the heavy object 1, a hoisting equipment (not shown) is provided in advance on the upper part of the installation place, and the hoisting equipment is hooked on the hoisting hook 6 to load the heavy object. 1 is suspended. At the same time, while closing the valve 5, the supply of compressed air to the truck 2 is gradually reduced, and when the truck 2 is separated from the heavy article 1, the heavy article 1 is installed at a predetermined place.

Here, the principle that the pedestal 2 floats will be described in detail with reference to FIG. FIG. 2 is a sectional view of the embodiment shown in FIG. The same reference numerals as those in FIG. 1 indicate the same objects. Figure 2
In the figure, 1-1 is a reinforcing plate for reinforcing the pedestal 2, and 7 is a floor surface. Compressed air is sent from the nozzle 4 to the lower portion of the pedestal 2, and the inside of the pedestal 2 is in a pressurized state as indicated by a, and when the pressure is commensurate with the weight of the heavy object 1, the lower portion of the pedestal 2 and its peripheral portion are Compressed air is blown out from between the resin sheet and the resin sheet. With the blowing of this compressed air, c
As described above, the entire pedestal 2 tries to float up from the floor surface 7 together with the heavy object 1. At this time, the blowout surface of the compressed air formed from the lower portion of the pedestal 2 and the floor surface 7 is not uniform over the entire lower portion of the pedestal 2, and the floor surface 7 has irregularities or the lower portion of the pedestal 2 has some irregularities. If there is, big and small occurs in the opening. A difference in flow rate occurs in the blown air depending on the size of the opening of the blown air surface. This flow rate difference sucks up the flexible resin sheet 3 from the floor surface 7 like d,
When the opening of the air blowing surface is large, it acts to close the opening and reduce the width of the opening of the air blowing surface. In this way, the resin sheet 3 automatically adjusts the opening width of the air blowing surface to keep the opening between the air blowing surface of the base 2 and the resin sheet 3 constant. As a result, the levitation force acts uniformly and uniformly on the entire lower part of the pedestal 2,
The whole pedestal can be raised. By the way, trolley 2
If the flexible resin sheet 3 is not used between the floor surface 7 and the floor 7, the size of the opening generated on the air blowing surface will continue to exist, and the levitation force on the pedestal 2 will be biased to a part of it.
The whole pedestal cannot be levitated.

As described above, in this embodiment, the box type trolley 2 is used.
By laying a flexible resin sheet 3 between the floor surface 7 and the floor surface 7, even if the floor surface 7 is uneven or the bottom of the pedestal 2 is uneven, the opening of the blowing surface of the pedestal 2 is made constant. Since it is kept, the whole pedestal can be floated, and by pushing the pedestal 2 with a small amount of energy, the heavy load 1 can be easily moved in the moving direction without giving vibration to the heavy load 1. Moreover, since the trolley | bogie 2 is a box type of a simple structure, the heavy load moving device can be simply comprised as a whole.

In the present embodiment, the sheet laid on the moving passage is the flexible resin sheet 3, but other flexible sheets such as a flexible cloth and a rubber sheet are also used. Exert the function of. Further, although the nozzle 4 is provided on the side portion of the pedestal 2, the nozzle may be attached at an arbitrary position such as the upper portion of the pedestal 2.

[0010]

As described above, according to the present invention,
By using a flexible seat at the bottom of the box-shaped trolley, the pedestal's air blowing surface is kept constant and the entire pedestal is in a floating state, so the floor is uneven or the floor is soft. Even with this, heavy objects can be easily transported with little energy without vibration. Further, since the pedestal for loading the heavy object has a simple box-shaped structure, the heavy object moving device can be simply configured as a whole.
