The invention relates to a container portal crane which comprises a mounting rail, supporting frames are fixedly connected to the two sides of the bottom of the mounting rail, a rolling device is arranged in the middle of the mounting rail in a sliding mode, a lifting mechanism used for lifting a container is arranged at the bottom of the rolling device, and the lifting mechanism rotates through a worm wheel to lift the container. A first servo motor is matched to operate to drive a winding device to wind the traction rope, so that the pulling force of the traction rope is improved, and the situation that when the first servo motor breaks down, a container suddenly falls, and a building below the container is damaged is avoided; the sliding block ascends under the limiting condition of the two limiting grooves, the clamping groove in the top face of the sliding block is connected with one clamping block in a clamped mode, a transmission mechanism is matched so that the crane can conveniently position the container, and the container is prevented from falling suddenly.
本发明涉及一种集装箱门式起重机,包括安装轨道,所述安装轨道的底部两侧均固定连接有支撑架,所述安装轨道的中部滑动设置有滚动装置,所述滚动装置的底部设置有用于提升集装箱的升降机构,通过蜗轮转动,从而带动两个摩擦轮带动牵引绳移动,配合第一伺服电机运转带动收卷设备收卷牵引绳,从而提高牵引绳的拉力,避免当第一伺服电机出现故障时,集装箱突然坠落,对其下方的建筑造成损伤,通过液压推杆伸长,使得滑块在两个限位槽的限位条件下进行上升,使得滑块顶面的卡槽与一个卡块卡合连接,配合传动机构使得方便起重机对集装箱进行定位,防止集装箱突然坠落。
