The invention relates to a novel direct-drive gantry crane, which is directly driven by a linear motor in planar motion. The device comprises a longitudinal rail provided with a longitudinal linear motor secondary, a longitudinal moving portal frame provided with a longitudinal linear motor primary, a rail provided with a transverse linear motor secondary and a transverse platform provided with a transverse linear motor primary, longitudinal supporting wheels are arranged at the bottom of the moving portal frame, and transverse supporting wheels are arranged at the bottom of the transverse platform. The longitudinal rails are respectively mounted on the left side and the right side of a longitudinal channel of the gantry crane; the linear motor secondary is mounted on the rails; according to the technology, a movement mechanism of the gantry crane can be simplified, the operation efficiency is improved, faults and maintenance are reduced, and the operation cost is reduced. Therefore, the gantry crane can be better applied.

    本发明涉及一种新型直驱龙门式起重机,它的平面运动均采用直线电机直接驱动,它包括装有纵向直线电机次级的纵向轨道、装有纵向直线电机初级的纵向移动龙门架、龙门架上装有有横向直线电机次级的轨道、装有横向直线电机初级的横向平台、移动龙门架底部装有纵向支撑轮、横向平台底部装有横向支撑轮,纵向轨道分别安装在龙门式起重机的纵向通道左右两侧,轨道上安装有直线电机次级;该技术可使龙门式起重机运动机构简化,运行效率提高,故障与维护减少,运行成本降低。从而使龙门式起重机得到更好的应用。
