Description

Auxiliary wheel mechanism for preventing shuttle from tipping

Technical Field

The utility model relates to the technical field of auxiliary structures of shuttles in logistics conveying equipment, in particular to an auxiliary wheel mechanism for preventing the shuttles from tipping.

Background

In various logistics conveying equipment existing in the market, the shuttle can easily solve goods distinguishing and can also carry out efficient transfer. The shuttle is gradually suitable for various conveying scenes by continuously pushing out the structure of the shuttle, and in most cases, the shuttle which is designed and produced by common equipment manufacturers is of a rectangular four-wheel structure due to the structural characteristics of the shuttle. The structure can well ensure that the shuttle is stable in bearing and the advancing direction is easier to control, and basically most of the shuttles on the market are the structure. In addition, part of the shuttle adopts a three-wheel group structure. Compared with a four-wheel structure of the shuttle, the three-wheel structure has the characteristics of more flexible steering and track change, and can realize the track layout of the annular shuttle by adopting smaller turning radius.

However, as the bearing surfaces of the shuttles with the three wheel group structures are still rectangular, and the suspension situation that the bearing surfaces of the shuttles cannot bear force exists at the bearing surfaces of the bottom wheel groups, the structure can cause the uncoordinated bearing structures of the bearing surfaces of the shuttles, and the condition that the shuttles are easy to tip over. When the shuttle is used for conveying goods, as the triangular stress structure bears the rectangular bearing surface, the gravity center of the bearing goods is easily deviated from the area stress center surrounded by the three wheel sets due to unbalanced goods placement positions, and the whole shuttle is tilted, so that dangerous accidents are caused. In order to reduce the possibility of overturning the shuttle, the wheel sets are required to be evenly divided as much as possible when the wheel sets are arranged in the structural design of the shuttle, so that the bearing structure is reasonably stressed. In addition, another common structure is to add an auxiliary wheel structure to one end of a single wheel group structure of the shuttle as a support to provide supporting force for the bearing surface of the shuttle.

When the method of equally dividing the shuttle wheel group by adopting the structural design is adopted, the stress structure of the wheel group needs to be evenly distributed as much as possible by improving the whole frame structure. The shuttle structure can be complicated, the structural improvement space is small, and the whole shuttle structure can be limited. In addition, if the whole shuttle is stressed by improving the frame structure of the vehicle body, the design difficulty of the shuttle is increased, and the specification and the use parameters become more single and complex structural design, so that the later maintenance of the equipment is inconvenient.

In another mode, when the three-wheel group structure is adopted, three wheel groups are uniformly distributed on three corners of the rectangular structure, and an auxiliary wheel structure for bearing force is arranged on the other corner of the rectangle. The overall structure of the shuttle is biased to the four-wheel shuttle structure, so that the flexibility advantage of the three-wheel shuttle is lost. Although the structure can inherit the flexibility of the three-wheel group shuttle to a certain extent, due to the limitation of the bearing structure of the auxiliary wheels, the auxiliary wheels need to be ensured to always support on the track plane, and when the turning radius of the facing annular track is smaller, the auxiliary wheels are easy to deviate from the track to cause the support deviation of the shuttle to tilt. Therefore, the structure still has the limitation of four-wheel structure, and enough turning radius is needed to ensure that the auxiliary wheel can play a normal supporting role, so we propose an anti-tipping auxiliary wheel mechanism of the shuttle.

Disclosure of Invention

Aiming at the problems, the utility model provides the auxiliary wheel mechanism for preventing the shuttle from tipping, which improves the design and arrangement flexibility of the shuttle on the annular track and ensures that the shuttle has a reasonable supporting structure, and the running is more stable.

Compared with a four-wheel group shuttle, the three-wheel group shuttle has fewer requirements on the arrangement of the tracks, namely, the three-wheel group shuttle has higher adaptation degree to various complex and compact annular shuttle track lines, and the complexity of track design can be further reduced. However, the three-wheel group shuttle is not as uniform as the four-wheel group shuttle in its wheel group distribution structure, so that the load bearing has certain defects, and when the goods are unbalanced, the gravity center of the goods is easy to deviate from the bearing center, so that the three-wheel group shuttle is tilted.

The utility model aims to design an auxiliary wheel structure for a three-wheel shuttle and complement places with defects of a wheel group supporting structure of the three-wheel shuttle. The three-wheel shuttle has good flexibility and rail applicability through the supporting bearing of the auxiliary wheels, and meanwhile stability of the three-wheel shuttle in structural transportation is further guaranteed.

In addition, the additional rollover detection device is designed on the auxiliary wheel, when the shuttle is inclined to a certain extent due to unbalanced load of goods, the speed of the shuttle can be reduced and even the operation is stopped, so that the possibility of rollover of the shuttle in the transportation process is avoided as much as possible.
