Detailed Description

The present invention is described in further detail below with reference to fig. 1 to 12. The original structure of the goods shelf is shown in figure 1, the shuttle car 4 can only walk in a straight line in a fixed track, and if the shuttle car 4 on the same track is encountered, the shuttle car cannot avoid the track.

In order to enable two shuttles 4 on the same track to be capable of avoiding, the invention discloses an avoiding structure, an avoiding type goods shelf and an avoiding method of the shuttles 4 running in the same direction, wherein the structure part comprises a main track 2 arranged on the goods shelf 1, the shuttles 4 moving along the main track 2, an avoiding track 3 arranged on the goods shelf 1 and an avoiding mechanism 5 moving along the avoiding track 3.

The avoidance track 3 is arranged right below the main track 2 and used for the movement of a bearing vehicle 53 of the avoidance mechanism 5; shuttle 4 is provided with wheels 41 movable on main track 2, and wheels 41 of shuttle 4 can realize track change by moving along splines. Fig. 4 is a wheel tread when the shuttle 4 normally travels with freight, and fig. 5 is a wheel tread when the shuttle 4 performs the avoidance function.

The avoidance mechanism 5 comprises a bearing vehicle 53 arranged on the avoidance track 3, a lifting mechanism 52 arranged on the bearing vehicle 53, and a supporting plate 51 arranged on the lifting mechanism 52; the bearing vehicle 53 moves along the avoidance track 3 and is responsible for conveying the avoidance mechanism 5 to the position below the shuttle vehicle 4 needing to be avoided; the lifting mechanism 52 is responsible for driving the supporting plate 51 to lift; pallet 51 is responsible for holding shuttle 4.

The avoidance method comprises the following steps:
