    • A piping travelling apparatus having a plurality of continuous treads (15) driven by motors (10) through transmission gearing (11). The continuous treads are mounted to a frame (20) and spaced apart a predetermined distance peripherally of the inner wall surface of the piping (3). At least one of the continuous treads is kept in contact with the inner wall surface of the piping no matter what the posture of the apparatus may be, so that the apparatus can travel without any trouble even if its posture undergoes a change when it moves along elevations and depressions on the inner wall surface of the piping or negotiates the boundary between different levels of the inner wall surface or bends of the piping. The apparatus enables a travel through piping of relatively small diameter having vertical or steeply slanted pipes to be made without any trouble.

    • PURPOSE:To obtain the running device which moves smoothly even in a small- diameter piping and a curved pipe by transmitting the rotation of an impeller by air to sheels, and providing a direction inverting mechanism to the wheels. CONSTITUTION:A driving wheel 1 and a driven wheel 2 are fitted to a barrel body in contact with the internal surface of piping, and the impeller 3 as a driving source has a rotating shaft 4 and is provided with a pneumatic container 5 convering the impeller 3. Air hoses 6a and 6b for sending air in the penumatic container 5 are fitted to the container 5 as an inflow and an outflow hose, rotating the rotating shaft 4 forward and backward. The power transmission between the driving wheel 1 and the rotating shaft 4 of the impeller 4 in the pneumatic container 5 is performed through a gear 7.
    • 目的:通过将叶轮的旋转通过空气传递到叶片,获得即使在小直径管道和弯曲管道中平稳移动的运行装置,并且向车轮提供方向反转机构。 构成:将驱动轮1和从动轮2装配到与管道内表面接触的筒体上,作为驱动源的叶轮3具有旋转轴4,并且设置有将叶轮会聚的气动容器5 将用于在阴极容器5内输送空气的空气软管6a,6b作为流入口和流出软管装配在容器5上,使旋转轴4向前后移动。 驱动轮1与气动容器5内的叶轮4的旋转轴4之间的动力传递通过齿轮7进行。
