| Zusammenfassung: | The invention discloses a portable hydraulic top drive device, which is mainly composed of a top drive (1) and a hydraulic pump station (2). The top drive is mainly composed of a hoisting mechanism, ashell, an output torque mechanism, a spindle, a faucet and an anti-torque mechanism, the hydraulic pump station delivers hydraulic oil into the output torque mechanism to drive the output torque mechanism to work, the spindle is driven to rotate and then connected with an external working part to drive the external working part to conduct workover operation, and thus the function of top driving is achieved. The top drive part in the portable hydraulic top drive device adopts a hydraulic motor as a power source, electricity connecting is not needed, convenient conditions are provided for limitation to field work, the number of component parts is small, the structure is simple, the weight is small, carrying is convenient, power of the portable hydraulic top drive device is not reduced compared with power of an exis |
