The invention provides a lifting device for a cab of construction equipment. The lifting device comprises an inner shear fork frame, an outer shear fork frame and a driving mechanism. The inner shear fork frame and the outer shear fork frame are hinged to form a shear fork mechanism, and the driving mechanism is arranged at the hinged position of the inner shear fork frame and the outer shear fork frame and used for achieving relative rotation between the inner shear fork frame and the outer shear fork frame. The driving mechanism comprises a driving motor and a speed reducer connected with a first output shaft of the driving motor. And an output shaft II of the speed reducer is inserted into the hinged part of the inner shear fork frame and the outer shear fork frame. The shear fork mechanism is formed by hinging the inner shear fork frame and the outer shear fork frame, installation is easy, and the space occupancy rate is small; through cooperation of the driving motor and the speed reducer, the lifting speed of the scissor mechanism can be controlled, lifting power is provided for the scissor mechanism, and the scissor mechanism has the advantages of being low in working noise, high in control precision, free of oil pollution and the like.

    本发明提供了一种施工设备驾驶室升降装置,包括内剪叉架、外剪叉架和驱动机构;所述内剪叉架和外剪叉架铰接形成剪叉机构,所述驱动机构设置于内剪叉架和外剪叉架的铰接处,用于实现内剪叉架和外剪叉架之间的相对转动;所述驱动机构包括驱动电机和与驱动电机的输出轴一连接的减速器;所述减速器的输出轴二插入内剪叉架和外剪叉架的铰接处设置。本发明通过内剪叉架和外剪叉架铰接形成剪叉机构,易于安装且空间占用率小;通过驱动电机和减速器配合,能够控制剪叉机构的升降速度,为剪叉机构提供升降动力,具有工作噪声小、控制精度高且没有油液污染等优点。
