7. The conveying vehicle with the jacking travelling devices and the horizontal guide wheels as claimed in claim 6, wherein when four travelling devices (5) in the conveying vehicle (3) rotate, the parts of the travelling wheel carriers (5-1) in the top projection of the vehicle body (3-1) rotate outwards, i.e. the travelling wheel carriers (5-1) do not interfere with articles (7) on the lifting tools (3-4) in the cavity (3-1-1) of the vehicle body (3-1) when rotating.
8. The conveyor with horizontal guide wheels of a jacking travelling device according to claim 7, wherein a transverse platform (4X-2) is included between two transverse guide rails (4X) in the transverse track (2X), and the empty conveyor (3) does not interfere with the articles (7) stored on the transverse platform (4X-2) when running along the transverse track (2X); a longitudinal platform (4Y-2) is arranged between two longitudinal guide rails (4Y) in the longitudinal rail (2Y), and the empty delivery wagon (3) does not interfere with the objects (7) stored on the longitudinal platform (4Y-2) when running along the longitudinal rail (2Y).
9. The conveyor car with horizontal guide wheels of a jacking traveling device according to claim 8, wherein the transverse rails (2X), the longitudinal rails (2Y) and the plane rails (2A) are allowed to have gaps with a length less than L.
