によっては空気供給手段の実現が不可能になる。However, in the case of the above-mentioned air pallet, since a heavy object is lifted together with the pallet only by the pressure receiving areas of the plurality of air bearing portions, high pressure air of 1 to 3 kgf / cm 2 is usually used. Need. In addition, such an air bearing forms a thin air film by escaping air between the air bearing and the floor surface, thereby preventing contact with the floor surface and greatly reducing frictional resistance with the floor surface. It should be low. For this reason, the air bearing must constantly supply high-pressure air escaping to the outside from the air film formed on the contact surface with the floor surface, and a large-capacity air supply means capable of constantly supplying a large amount of high-pressure air is required. Become. Moreover, the amount of air that escapes from the air film is p
Since it is proportional to 1/2 (p = air pallet internal pressure), the higher the pressure, the higher the air consumption. Therefore, in a moving device for moving a heavy object, it is necessary to provide a large amount of high-pressure air to the air bearings, which requires a large amount of cost to provide an air supply unit. Depending on the size of the moving device, the air supply unit may be realized. Becomes impossible.

Are provided with blowers 3 and 6 for making the lower space i and the inner space s of the sealing material 7 a predetermined internal pressure, respectively.
In the case of (a), a blower 3 having a capacity capable of setting the lower space i to a predetermined internal pressure and a blower s having a capacity of setting the internal space s to a predetermined internal pressure are provided. A blower 3 having a capacity capable of setting the space i to a predetermined internal pressure and a blower 6 having a capacity capable of setting the internal space s to a predetermined internal pressure from the compressed air in the lower space i are provided. Therefore, in the case of the configuration (b), the capacity of the blower 6 can be reduced, and the apparatus can be made more compact. The configuration of these air supply means may be appropriately adopted according to the size of the moving device M, the internal pressure, and the like.

移動させても床面Ｇとのシール性を保つことができる。According to the sealing device N configured as described above, the sealing function is maintained in a state in which the moving device M is floated by a predetermined amount by operating as follows, and the moving device M can be moved in a floating state. The sealing performance with the floor surface G can be maintained.

ール性を確保することができる。That is, compressed air is supplied to the lower space i by the air blower 3 to make the inside of the lower space i a predetermined pressure, so that the entire moving device M floats by a predetermined amount. By supplying compressed air at a predetermined pressure to the inner space s of the seal 7, the internal pressure of the seal member 7 is increased and the seal member 7 is brought into contact with the floor surface G at a predetermined contact pressure. At this time, the inner space s of the sealing material 7 is smaller than the inner pressure acting on the lower space i.
Since the internal pressure acting on the floor member G is set to be high (substantially equal to or more than the above), the sealing member 7 can be kept pressed against the floor surface G to ensure the sealing performance.

大重量の移動装置Ｍを浮上させることができる。As described above, in order to prevent air leakage by the surrounding sealing member 7 while supplying the air of the predetermined pressure to the lower space i and floating the moving device M by the predetermined amount, the lower space i is temporarily connected to the lower space i. When air of a predetermined pressure is supplied to the space s, the amount of air for maintaining the pressure is sufficient thereafter, and the heavy moving device M can be levitated with a small amount of air. In addition, since there is no air leakage from the lower space i, the heavy moving device M can be levitated at a low pressure.

常に安定したシール機能を発揮させることができる。The internal pressure acting on the internal space s of the sealing member 7 and the internal pressure acting on the lower space i of the moving device main body 1 are adjustable, and these air pressures are reduced by the blowers 6 and 3 serving as air supply means. By adjusting, the contact pressure between the sealing material 7 and the floor surface G can be freely changed. Thus, the inner pressure acting on the inner space s and the lower space i
The internal pressure acting on the floor surface G can be relatively adjusted, so that the sealing member 7 can flexibly follow the unevenness or the inclined state of the floor surface G, and is always stable according to any floor surface G. A sealing function can be exhibited.

1 kgf / cm 2 ), the moving device M is levitated by a predetermined amount, and the traveling device 4 drives the wheels 5 to move while supporting the predetermined weight of the moving device M. Prevents leakage and enables stable movement.

When increasing the internal space s to 1200 mmAq, the blower 3 needs a capacity capable of increasing the lower space i to 1000 mmAq. However, the blower 6 has a capacity of 200 mmAq capable of further increasing the internal space s from 1000 mmAq to 1200 mmAq. It will be good. Therefore, in such a configuration, the size of the blower 6 can be reduced.

The wear-resistant material 11 is adhered to a surface of the sealing material 7 made of a soft material such as chloroprene rubber, which is in contact with the floor surface G.

型化を図ることができる。Further, by selecting the wear-resistant material 11, the frictional resistance with the floor surface G can be reduced, so that the traveling resistance of the moving device M can be reduced and the drive device 4 can be downsized. .
【００２７】なお、この第２実施形態では、シール材７
の床面Ｇとの接触面側のみに耐摩耗材１１を設けている
が、前記第１実施形態におけるシール材７自体を耐摩耗
性材料で形成しても同様の作用効果を得ることができ、
使用条件等に応じて耐摩耗性を発揮させる構成は適宜選
択すればよい。In the second embodiment, the sealing material 7
Although the wear-resistant material 11 is provided only on the contact surface side with the floor surface G, the same operation and effect can be obtained even if the seal material 7 in the first embodiment is formed of a wear-resistant material.
The configuration for exhibiting wear resistance may be appropriately selected according to the use conditions and the like.

【発明の効果】この出願に係る発明は、以上説明したよ
うな形態で実施され、以下に記載するような効果を奏す
る。The invention according to this application is implemented in the form described above, and has the following effects.
【００２９】移動装置を昇降あるいは移動させた時で
も、移動装置の周囲に設けたバグ型のシール材が床面の
凹凸等に追随して変形し移動装置周囲のシール性を保つ
ことができる。しかも、少ない空気量と低い空気圧力で
大重量物を移動させる移動装置を容易に昇降させること
が可能となる。Even when the moving device is moved up and down or moved, the bag-type sealing material provided around the moving device deforms following irregularities on the floor surface and the like, and the sealing property around the moving device can be maintained. In addition, it is possible to easily move up and down a moving device that moves a heavy object with a small amount of air and a low air pressure.
【００３０】また、シール材の床面との接触面に耐摩耗
材を設けることにより、移動装置を移動させても高い耐
摩耗性によってシール材の長耐用寿命化を図ることがで
きる。Further, by providing a wear-resistant material on the contact surface of the seal material with the floor surface, the service life of the seal material can be prolonged due to high wear resistance even when the moving device is moved.
