The invention discloses a clutch type rope threading hoisting mechanism for a crane, relates to the technical field of clutch type hoisting mechanisms, and particularly relates to a hoisting mechanismwhich is applied to a large crane and is used for threading and tensioning a hoisting steel wire rope on an arm frame. The clutch type rope threading hoisting mechanism comprises a hydraulic motor, arack, a winding drum, a planetary gear train, a steel wire rope, a clutch, a rope pressing device and a guide device, wherein the rack is connected to the crane through a pin shaft; the winding drumis arranged inside the rack and can rotate inside the rack; the planetary gear train is arranged in the winding drum; the input end of the planetary gear train is connected with the hydraulic motor arranged on one side of the rack, and the output end of the planetary gear train is connected with the clutch arranged on the other side of the rack; the steel wire rope is wound on the outer wall of the winding drum; the guide device is arranged on the rack in the rope outlet direction of the steel wire rope; the rope pressing device is arranged on the rack on the side opposite to the rope outlet direction of the steel wire rope; and the hydraulic motor is connected with the winding drum through the planetary gear train and drives the winding drum to rotate, and after speed reduction and torqueincrease, the steel wire rope is finally output to the steel wire rope through the winding drum, so that winding and unwinding of the steel wire rope are realized.

    本发明起重机用离合式穿绳卷扬机构,涉及离合式卷扬机构技术领域,尤其涉及应用在大型起重机上,用来在臂架上穿引并张紧起吊钢丝绳的卷扬机构。本发明包括:液压马达、机架、卷筒、行星轮系、钢丝绳、离合器、压绳器和导向装置;机架通过销轴连接在起重机上;卷筒设置于机架的内部,并可在机架内部转动;卷筒内置有行星轮系;行星轮系的输入端与装于机架一侧上的液压马达相连接,输出端与装于机架另一侧上的离合器相连接;钢丝绳缠绕在卷筒的外壁上;钢丝绳出绳方向的机架上设置有导向装置;钢丝绳出绳方向相反一侧的机架上设置有压绳器;液压马达通过行星轮系与卷筒连接,并带动卷筒转动,经减速增扭后,最终通过卷筒输出给钢丝绳,实现钢丝绳的收放。
