The invention discloses a main driving system for a power catwalk and the power catwalk using the main driving system, and belongs to the technical field of power catwalks of oil and gas drilling and production equipment. The main driving system for the power catwalk comprises a ramp and further comprises a main driving mechanism arranged on the ramp; the main driving mechanism comprises a sliding trolley, a guide wheel unit, a rope and a rope pulling and releasing driving structure; and the sliding trolley is assembled on the front surface of the ramp and can slide up and down along the front surface of the ramp, the guide wheel unit is arranged on the top of the ramp, the rope pulling and releasing driving structure is assembled on the back surface of the ramp, the rear end of the rope is fixed to the back surface of the ramp, and the front end of the rope is connected with the sliding trolley after bypassing the rope pulling and releasing driving structure and the guide wheel unit. According to the main driving system of the power catwalk, the sliding trolley can slide up and down along the front surface of the ramp through the rope pulling and releasing action of the rope pulling and releasing driving structure, that is, ascending and descending of the sliding trolley are achieved, and then ascending/descending action of a turnover type V-shaped drilling tool supporting beam can be achieved.

    本发明公开了一种用于动力猫道的主驱动系统及其动力猫道,属于油气钻采设备的动力猫道技术领域。本发明的一种用于动力猫道的主驱动系统,包括坡道,还包括设置于坡道上的主驱动机构;所述主驱动机构包括滑车、导向轮单元、绳子和拉放绳驱动结构;所述滑车装配于坡道正面并可沿坡道正面上下滑动,导向轮单元设置于坡道顶部,拉放绳驱动结构装配于坡道背面,绳子后端固定于坡道背面,绳子前端绕过拉放绳驱动结构以及导向轮单元后与滑车相连。本发明动力猫道的主驱动系统,通过拉放绳驱动结构的拉放绳动作能够使得滑车沿坡道正面上下滑动,即实现了滑车的上下行,进而可以用以实现翻折式V型钻具支撑梁的上升/下降动作。
