Manual stepping type car body main welding line skid conveying system

The invention discloses a manual stepping type car body main welding line skid conveying system. The manual stepping type car body main welding line skid conveying system comprises a conveying split sliding rail. A roller bed split skid is installed on a conveying jacking structure. Pneumatic jacking devices are arranged under the conveying sliding rail. A roller bed is provided with the manual stepping hand-push split type roller bed skid. An electronic control unit controls the pneumatic jacking devices to conduct automatic jacking, so that the skid is automatically conveyed. According to the manual stepping type car body main welding line skid conveying system, a set of independent jacking sliding mechanism is adopted, system production synchronization is ensured, the split type skid can overcome the defect that the structure is unique, the conveying method is flexibly adjusted, and the capacity requirements are met; compatible using among welding stations can be achieved, the cost is reduced, the situatio
