Flexible rolling belt-based conveying apparatus

A flexible rolling belt-based conveying apparatus, comprising a plurality of rolling body units, wherein each rolling body unit comprises a support;

• a power roller is arranged above the support;
• locomotion wheels are arranged on two sides of the support;
• a chain link unit is arranged in the middle of the support;
• a guide wheel is mounted below the chain link unit;
• the plurality of rolling body units are sequentially connected front and back through the chain link units;
• the rolling body units are able to rotate in a horizontal direction and a vertical direction to form a continuous flexible conveying rolling belt;
• each chain link unit comprises a main chain link and an auxiliary chain link;
• a horizontal convex lug is arranged in the middle of a front end of the main chain link;
• a main longitudinal hinge hole is longitudinally provided in the horizontal convex lug;
• vertical convex lugs are arranged on two sides of a rear end of the main chain link;
• main transverse hinge holes are horizontally provided in the vertical convex lugs;
• an auxiliary longitudinal hinge hole that is adapted to the main longitudinal hinge hole and auxiliary transverse hinge holes that are adapted to the main transverse hinge holes are provided in the auxiliary chain link;
• the auxiliary longitudinal hinge hole and the auxiliary transverse hinge holes are arranged in the same plane;
• the main longitudinal hinge hole and the auxiliary longitudinal hinge hole are hinged through a longitudinal hinge shaft, and the main transverse hinge holes and the auxiliary transverse hinge holes are hinged through a transverse hinge shaft;
• the transverse hinge shaft and the longitudinal hinge shaft form a crosswise structure and are in no contact at a center of the crosswise structure;
• a limiting slot structure is further arranged on the main chain link of each chain link unit;
• the limiting slot structure comprises a transverse limiting slot arranged behind the main longitudinal hinge hole, and longitudinal limiting slots arranged in front of the main transverse hinge holes;
• a limiting hole structure corresponding to the limiting slot structure is arranged on the auxiliary chain link;
• the limiting hole structure comprises a transverse limiting hole arranged behind the auxiliary longitudinal hinge hole, and longitudinal limiting holes arranged in front of the auxiliary transverse hinge holes;
• the transverse limiting slot and the transverse limiting hole are connected through a longitudinal limiting pin for horizontal transverse limitation;
• the longitudinal limiting slots and the longitudinal limiting holes are connected through a transverse limiting pin for vertical longitudinal limitation;
• and
• the transverse limiting slot and the longitudinal limiting slots are both fan-shaped through slots.
