Sorting loop line track assembly

According to the sorting loop line rail assembly, an overall frame modular structure design is provided, the butt joint position structure is optimized on the basis of the modular overall structure, and therefore standardization and universality of the rail butt joint technology are improved, and the problems that butt joint between rails is uneven, and accuracy is poor are fundamentally solved. On the basis of improving the stability of the whole structure and the attractive appearance, the convenience of field installation, disassembly and maintenance operation is effectively improved. And the rail assembly is formed by welding and machining a group of lower connecting plates, a plurality of groups of rail rib plates, two groups of body bending pieces which are symmetrically arranged, aplurality of groups of reinforcing ribs, a group of upper connecting blocks and a pair of lower connecting blocks, wherein the group of upper connecting blocks and the pair of lower connecting blocksare positioned on one grou
