Hereinafter, embodiments of an air cushion transferring apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic view illustrating an air cushion transferring apparatus according to an embodiment of the present invention.

Referring to FIG. 2, the air cushion transferring apparatus 100 according to the present embodiment is capable of adjusting the floating force by deforming the shape of the air cushion if necessary, and includes a frame 110, an air cushion 120, And an air cushion deforming portion 130.

On the upper surface 111 of the frame 110, a cargo 2 is loaded and generally formed in a flat plate shape.

An inlet 121 for connecting a flow path between an external compressor (not shown) and an air cushion 120 to be described later may be formed through the frame 110. The air 1 supplied from an external compressor (not shown) flows into the air cushion 120 through the inlet 121 and the air cushion 120 is expanded .

The air cushion 120 is installed on the lower surface 112 of the frame 110 and is formed in a tubular shape along the edge of the frame 110.

The air 1 supplied from the outside flows into the air cushion 120 through the inlet 121 so that the air cushion 120 can be inflated and the pressure inside the air cushion 120 can be increased The air 1 is blown into the inner spaces S1 and S2 between the lower surface 112 and the bottom surface 3 of the frame 110 through the jet port 122 and the air cushion transfer device 100 Is floated.

The air cushion transferring apparatus 100 is configured such that the air 1 is strongly ejected to the bottom surface 3 and an air film is formed between the air cushion unit 120 and the bottom surface 3, It is possible to support the weight of the cargo 2 and float from the bottom surface 3, whereby the cargo 2 with high load can be easily carried.

The air cushion deforming part 130 is provided on the lower side of the frame 110 and deforms the shape of the air cushion part 120.

As described above, the lifting force of the air cushion transferring apparatus 100 is determined by the inner space 124 defined by the lower surface 112 of the frame 110, the bottom surface 3, and the inner surface 124 of the air cushion 110 Is proportional to the product of the pressure of the air 1 in the inner spaces S1 and S2 and the area of the inner bottoms A1 and A2 in contact with the air 1 in the inner spaces S1 and S2.

2 (a) and 2 (b) will be described with the pressure of the air 1 supplied from an external compressor (not shown) being constant.

2 (a), when the volume of the inner space S1 is relatively large, the air 1 blown out through the air outlet 122 of the air cushion unit 120 flows into the inner space S1 The time required to fill up is relatively long. However, since the area of the inner bottom surface A1 that is in contact with the air 1 in the inner space S1 becomes relatively large, the pressure of the air 1 in the inner space S1 and the inner bottom surface A1, The flying force of the air cushion conveying apparatus 100, which is proportional to the product of the area of the air cushion conveying device 100, becomes relatively large.

When the area of the inner bottom surface A1 is large, the lifting force of the air cushion conveying apparatus 100 becomes large and the load of the transportable load 2 can be increased. However, since the large volume of the inner space S1 The time required for forming the flotation force is somewhat long.

On the other hand, when the volume of the inner space S2 is relatively small as shown in FIG. 2 (b), the air ejected through the ejection port 122 of the air cushion unit 120 is filled in the inner space S2 The time required to complete the process is relatively short. However, since the area of the inner bottom surface A2 contacting the air 1 in the inner space S2 becomes relatively small, the pressure of the air 1 in the inner space S2 and the pressure of the inner bottom surface A2 The lifting force of the air cushion transfer device 100 proportional to the product of the area of the air cushion transfer device 100 becomes relatively small.

When the area of the inner bottom surface A2 is small, the lifting force of the air cushion conveying apparatus 100 becomes small and the load of the conveyable load 2 becomes low. However, due to the small volume of the inner space S2 There is an advantage that the time required for forming the floating force is shortened.

The air cushion deforming portion 130 of the present embodiment deforms the shape of the air cushion portion 120 to change the area of the inner bottom surfaces A1 and A2 contacting the air 1 in the inside spaces S1 and S2 Thereby adjusting the lifting force of the air cushion transferring apparatus 100. [0054]

2, the air cushion deforming portion 130 is provided on the outer side of the air cushion portion 120 and deforms the shape of the air cushion portion 120 while pressing the air cushion portion 120 from the outside to the inside And includes a pressure plate 131 and a driving unit (not shown).

The pressure plate 131 may be disposed on the outer side of the air cushion 120 and one end may be coupled to the bottom surface 112 of the frame 110 and the other end may be disposed toward the bottom surface 3. A single pressure plate may be disposed to surround the air cushion 120 along the circumferential direction from the outside of the air cushion unit 120 and a plurality of pressure plates may be disposed outside the air cushion unit 120 at a predetermined interval And may be disposed while being spaced apart.

The driving unit (not shown) provides driving force for rotating the pressing plate 131 around the engaging part 132 where the pressing plate 131 and the lower surface 112 of the frame 110 are coupled. As the driving unit, various driving sources such as a motor driven by an electric line and a pneumatic cylinder driven by a pneumatic pressure may be used.

2 (a), since the pressure plate 131 does not press the outer surface 123 of the air cushion unit 120 in a state in which the driving unit is not operated, the area of the inner bottom surface A1 The lifting force of the air cushion transfer device 100 becomes relatively large. Therefore, although it takes a somewhat longer time to fill the air space S1 in the inner space S1, it is desirable to maintain such a state when a heavy load is to be transferred.

2B, when the driving unit is operated, the driving unit rotates the pressure plate 131 toward the air cushion unit 120 so that the pressure plate 131 contacts the air cushion unit (not shown) The area of the inner bottom surface A2 becomes relatively small and the lifting force of the air cushion transfer device 100 becomes relatively small. Accordingly, the load of the air-cushion conveying apparatus 100 is reduced and the load of the conveyable load is reduced. However, since the time for filling the air 1 in the inner space S2 is shortened, It is desirable to maintain such a state.

Fig. 3 is a view schematically showing a first modification of the air cushion transferring device of Fig. 2;

3, the air cushion deforming portion 140 of this modified example is provided on the outer side of the air cushion portion 120 and is provided on the outer side of the air cushion portion 120 while pressing the air cushion portion 120 inward from the outside. And includes a pressure plate 141 and a driving unit (not shown).

[ A single pressure plate may be disposed to surround the air cushion 120 along the circumferential direction from the outside of the air cushion unit 120 and a plurality of pressure plates may be disposed outside the air cushion unit 120 at a predetermined interval And may be disposed while being spaced apart.

The driving unit (not shown) provides a driving force to reciprocate the pressure plate 141 along a direction parallel to the bottom surface 3. [ As the driving unit, various driving sources such as a motor driven by an electric line and a pneumatic cylinder driven by a pneumatic pressure may be used.

3 (a), since the pressure plate 131 does not press the outer surface 123 of the air cushion unit 120 in the state where the driving unit is not operated, the area of the inner bottom surface A1 It is desirable to maintain such a state when the load is relatively large and a heavy load is to be transferred.

3B, when the driving unit is operated, the driving plate moves the pressure plate 141 toward the air cushion unit 120 (D2), and the pressure plate 141 is moved to the air cushion unit 120, the area of the inner bottom surface A2 becomes relatively small. Therefore, the time for filling the air 1 in the inner space S2 is shortened, so that it is preferable to maintain such a state when the cargo is to be transported quickly.

FIG. 4 is a view schematically showing a second modification of the air cushion transfer device 100 'of FIG.

4, the air cushion deforming portion 150 of this modified example is provided inside the air cushion portion 120 and is configured to press the air cushion portion 120 outwardly from the inside to the outside of the air cushion portion 120 And includes a pressure plate 151 and a driving unit (not shown).

The driving unit (not shown) provides a driving force for rotating the pressing plate 151 about the engaging part 152 where the pressing plate 151 and the lower surface 112 of the frame 110 are engaged. As the driving unit, various driving sources such as a motor driven by an electric line and a pneumatic cylinder driven by a pneumatic pressure may be used.

4A, since the pressure plate 151 does not press the inner surface 124 of the air cushion unit 120 in the state where the driving unit is not operated, the area of the inner bottom surface A3 It becomes relatively small. Therefore, the time for filling the air 1 in the inner space S3 is shortened, so that it is desirable to maintain such a state when the cargo is to be transferred quickly.

4B, when the driving unit is operated, the driving plate rotates the pressure plate 151 toward the air cushion unit 120 (D3), and the pressure plate 151 is rotated by the air cushion unit The inner space S4 is pressed against the inner side surface 124 of the inner bottom surface 120 so that the area of the inner bottom surface A4 is relatively large, .

Although not shown in the drawings, a modification combining the modification shown in Fig. 4 and the modification shown in Fig. 3 is also possible.

That is, the pressure plate of the air cushion deforming portion of this modification is provided on the inner side of the air cushion portion 120, one end portion is coupled to the lower surface 112 of the frame 110 and the other end portion is disposed toward the bottom surface 3 .
