The invention discloses a lifting type core-pulling machine capable of self-adjusting gravity center, which comprises guide rails and a propelling mechanism, a connecting body is arranged between the two guide rails, a weight adjusting motor is arranged at the tail end of each guide rail, a transverse structural plate is arranged at the front end of each guide rail, a side plate is arranged on the outer side of each guide rail, the front end of each side plate is connected with the transverse structural plate, and the tail end of each side plate is connected with a connecting plate. The side plate is provided with a hoisting mechanism, a movable hoisting column is arranged on the outer side of the tail end of the side plate, the two ends of the movable hoisting column are hinged to the side plate, hoisting holes are formed in the two ends of the movable hoisting column, and the transverse structural plate, the bottom of the movable hoisting column and the bottom of the connecting body are connected through a threaded lead screw which is in threaded connection with the connecting body and the bottom of the movable hoisting column. The threaded lead screw is connected with the transverse structural plate through a bearing, and the power end of the weight adjusting motor is connected with the threaded lead screw through a belt. The weight adjusting motor is adopted to drive the threaded lead screw to feed, then the movable davit is pushed to adjust the lifting position, the purpose of keeping lifting balance is achieved, and the lifting device can be widely applied to the field of petroleum refining maintenance.

    本发明公开了一种自我调节重心的起吊式抽芯机,包括导向轨及推进机构,两根导向轨之间设有连接体,导向轨尾端设有调重电机,导向轨前端设有横向结构板,导向轨外侧设有侧板,侧板前端与横向结构板相连,侧板尾端与连接板相连,侧板设有吊装机构,侧板尾端外侧设有活动吊柱,活动吊柱两端与侧板铰接,活动吊柱两端设有吊孔,横向结构板、活动吊柱底部和连接体底部均于一根螺纹丝杠相连,螺纹丝杠与连接体和活动吊柱底部螺纹相连,螺纹丝杠与横向结构板轴承连接,调重电机的动力端与螺纹丝杠通过皮带相连。本发明通过采用调重电机带动螺纹丝杠进给,进而推动活动吊柱调节起吊位置,从而达到保持吊装平衡的目的,可以广泛应用于石油炼化检修领域。
