The invention relates to the technical field of construction machinery, and discloses a high-stability lifting device for the construction machinery. The device comprises a bottom plate, wherein a U-shaped frame is fixedly connected to the side wall of the upper side of the bottom plate, through holes are formed in the side walls of the left side and the right side of the U-shaped frame, and the hole walls of the two through holes are rotationally connected with the same rotating shaft through ball bearings. The side wall of the right side of the U-shaped frame is fixedly connected with a driving motor, an output shaft of the driving motor is fixedly connected with one end of the rotating shaft, two wire twisting wheels fixedly sleeve the rotating shaft, steel ropes are wound around the wire twisting wheels, and the lower ends of the two steel ropes are fixedly connected with the same lifting platform. According to the high-stability lifting device for the construction machinery, the service life of the lifting platform is effectively prolonged, and the stability of the lifting platform is effectively improved.

    本发明涉及建筑机械技术领域,且公开了一种建筑机械用高稳定性升降装置,包括底板,所述底板上侧的侧壁固定连接有U型架,所述U型架左右两侧的侧壁均开设有通孔,两个所述通孔的孔壁通过滚珠轴承转动连接有同一根转轴,所述U型架右侧的侧壁固定连接有驱动电机,所述驱动电机的输出轴与转轴的一端固定连接,所述转轴外固定套设有两个绞线轮,所述绞线轮上绕设有钢绳,两根所述钢绳的下端固定连接有同一个升降平台。本发明有效的提高了升降平台的使用寿命和稳定性。
