Description

The invention relates to transport equipment, and more particularly to walking mechanisms for moving transport vehicles.

Known mechanisms for transport cargo containing a platform and a mover of step movements [1].

Of all the known analogues, the walking mechanism, which includes interconnected rotary platforms carrying sections of rail guides and power cylinders for lifting the platforms, is closest to the essential features declared in their aggregate [2].

In this device, the platforms are made in the form of disks enclosed in cages pivotally connected to each other and rotatable relative to each other in the horizontal plane using a slewing-rotary mechanism. The lifting rams are mounted on the axis of the articulation of the clips and are connected to them by articulated rods. The known device has increased complexity associated with the presence of lifting rams and associated articulated rods.

The invention is aimed at simplifying the design of the mechanism and increasing its reliability.

This is achieved by the fact that the rotary platforms are installed at the ends of a strip bent along an arc of a circle and having less than one half-turn. In addition, rail sections are laid on the strip section between the platforms.

Figure 1 shows a transport machine equipped with four proposed mechanisms, side view.

Figure 2 shows a General diagram of the movement of the mechanism, side view.

Figure 3 shows the General scheme of movement, top view.

The transport mechanism of the transport machine having a housing 1, wheels 2, mounted on an arm 3, includes a running gear made in the form of a strip 4, curved in an arc of a circle and having less than one half-turn, and rotary reinforced at the ends of this strip relative to its platform 5, bearing rail guides. Guides are laid in the section of the strip between the platforms. Rail guides interact with wheels 2. The drive of rotation of the platforms can be made in the form of a gear rim mounted on a cage and a pinion gear interacting with it. The drive is indicated by the number 6.

The disks are pivotally mounted on the lower side of the platform 4, while its upper side has rail guides along the entire length. In addition, an additional slewing joint is provided above the wheels.

The general movement pattern is shown in FIGS. 2 and 3 and consists in the sequential movement of the transport machine along rail guides located on the platforms and between the platforms. In the initial period of movement, the guides on the platforms and on the strip section between the platforms are oriented in the same direction. This occurs by the corresponding rotation of the platforms 5 with the help of the drives 6. The supporting-driving wheels 2 are located on the site between the platforms. Then the wheel drive is turned on, and the mechanism moves along the guides. In this case, the wheels pass from the section between the platforms to one of the platforms 5. Under the influence of the weight of the mechanism, the curved strip 4 together with the platforms 5 attached at its ends is rolled relative to the point of contact. When the wheels will be in the center of the support platform, i.e. the touch point will be in the center of this platform, the wheel drives will stop. At this moment, the rotation drive 6 is turned on and the wheels 4, together with the other platform, rotate 180 ° relative to the fixed platform. The guides on both platforms and between them are again oriented in the same direction. The wheel drive turns on, the mechanism again moves along the guides. The wheels pass from the platform to the portion of the strip between the platforms and, accordingly, to the opposite platform. The cycle of motion repeats. To rotate the machine, it is enough to rotate the platform relative to the strip not 180 °, but a larger or smaller angle. The machine can be equipped with several mechanisms.

The proposal to use the supporting-running apparatus, made in the form of a strip curved along an arc of a circle with rotary platforms fixed at its ends, has an advantage, since the presence of power cylinders that lift the platforms during their movement is excluded. This leads to a simplification and increased reliability of the mechanism. In addition, when applied sufficiently long relative to the diameter of the platform of the strip, the length can be significantly increased compared with the prototype.
