The invention discloses a petroleum drill rod elevating system. The petroleum drill rod elevating system comprises a drill rod elevator body, two centralizer connection devices are arranged on the drill rod elevator body, each centralizer connection device comprises two centralizer connection lug plates mounted on the outer side of the drill rod elevator body and a chain structure arranged between the two centralizer connection lug plates, a cavity for clamping a centralizer connection column is formed among each chain structure and the corresponding centralizer connection lug plates, the centralizer connection columns are inserted into the cavities, each chain structure comprises a plurality of chain rotating shafts with axes parallel to one another, a chain connection plate is connected between two adjacent chain rotating shafts, two chain rotating shafts two ends of each chain structure are connected to the centralizer connection lug plates respectively, each chain rotating shaft penetrates the corresponding centralizer connection lug plate, and axes of the chain rotating shafts are parallel to axes of the centralizer connection columns. The petroleum drill rod elevating system has the advantage that the problem of slipping in connections among lug plate structures and the centralizer connection columns is solved.
Description
technical field [0001] The invention relates to an elevator system for oil drilling pipes. Background technique [0002] The oil drill pipe elevator system is a tool used to lift drill pipe, oil pipe, casing and other pipes. It is hung in the rings on both sides of the hook of the lifting system, so as to lift out or run into the drilling tool in the wellbore. And tubing, casing operations. [0003] During drilling and workover operations, the elevator device is used to directly hang the wellhead tool of the pipe string, connect the lifting ring, and hang different pipe strings with different apertures. Elevators often bear the weight of all pipe strings in the top drive system, and also play an irreplaceable role in the process of taking over and unloading pipes. According to the different pipe strings suspended, they can be divided into sucker rod elevators, drill pipe elevators, Casing elevators and tubing elevators. [0004] During the pipe loading process, the me...
