Abstract
A pair of dual-purpose dynamic tongs for well drilling mainly aims to solve the problems of complicated process, low work efficiency, relatively great labor intensity of workers and the existence of safety hazards due to the repeated change of two various pairs of dynamic tongs during the process of well drilling. The tongs are characterized in that a constant-power, independent variable pump (12) is arranged inside a power station (10); a low voltage loop (9) is connected in parallel with the dynamic tongs (8) which are disposed inside a control box provided with a valve plate (7); an overflow valve (14) and a ball valve (13) are arranged on the loop (9) which is respectively connected with a voltage regulation handle (2) and an operating handle (4) mounted on the valve plate (7); and interfaces (1 and 3) connected with the oil feeding port and the oil return port of a hydraulic motor (17), and interfaces (5 and 6) connected with the oil feeding port and the oil return port of the power station (10) are further fixed on the valve plate (7). By employing the variation of the output flow of the hydraulic system, the tongs can achieve the swift switch from parameters for drill pipe dynamic tongs to parameters for casing power tongs. Therefore, the dual-purpose tongs have the advantages of avoiding the operating process of repeatedly changing hydraulic tongs, and enhancing the safety of the operation of equipment while improving the work efficiency and reducing the labor intensity of workers.
