The invention discloses a rail type container portal crane, and relates to the technical field of cranes, the rail type container portal crane comprises two bases, sliding columns are welded to the tops of the two bases, and sliding ways are formed in the two sides of the two sliding columns. When the rail type container portal crane is used, when a trolley body runs to the middle of a reinforcing cross beam and breaks down, the reinforcing cross beam drives a trolley assembly to integrally descend, an output shaft of a servo motor is made to rotate by starting the servo motor, so that a driving inner gear is driven to rotate, and a connecting toothed chain is meshed with a driven inner gear to enable the driven inner gear to rotate; the driven inner gear can drive the lifting lead screws to rotate, the rotating directions of the two lifting lead screws are the same, the lifting lead screws rotate to drive the two lifting blocks to move downwards in a threaded mode, then the two lifting blocks drive the reinforcing cross beam and the trolley assembly to move downwards, and maintenance work can be completed without the help of a high-altitude operation vehicle.
本发明公开了一种轨道式集装箱门式起重机,涉及起重机技术领域,包括:基座,所述基座设置有两个,两个所述基座的顶部均焊接有滑柱,两个所述滑柱的两侧均开设有滑道。该轨道式集装箱门式起重机,在使用时,当小车本体运行到加强横梁的中间处出故障时,便使加强横梁带动小车组件整体下降,通过启动伺服电机,使得伺服电机的输出轴转动,从而带动主动内齿轮转动,连接齿链咬合从动内齿轮使其转动,从动内齿轮会带动升降丝杆转动,两个升降丝杆的转动方向是相同的,升降丝杆转动会螺纹带动两个升降块向下移动,那么两个升降块便带动加强横梁和小车组件向下移动,不需要借助高空作业车辆便能够完成维修工作。
