Abstract
The invention relates to an overground operating string delivery mechanism for lifting a drill pipe, an oil pipe and the like of an overground operating platform. The overground operating string delivery mechanism comprises a catwalk body and a bit feeding pulley; the catwalk body is provided with a V-shaped slideway; the bit feeding pulley is arranged on the catwalk body and slides along the V-shaped slideway; a folding lifting support system is arranged below the catwalk body; the bit feeding pulley is provided with a driving mechanism; 1 to 4 slots are formed on the catwalk body at intervals; a conveyor belt system is arranged in the slots; the conveyor belt system and the V-shaped slideway are arranged in horizontal and perpendicular directions; two ends of the conveyor belt system extend outwards from two sides of the catwalk body; the conveyor belt system is linked with a lifting cylinder fixed to the catwalk body. The delivery mechanism lifts a string on a pipe rack to a drill floor in a mechanical mode, the degree of automation of drilling rig operation is increased, the labor intensity and the labor cost are reduced, and the safety is improved. The overground operating string delivery mechanism can be widely applied to automation renovation in the fields of oil rigs and workover rigs.
