The invention discloses a portal crane with an anti-collision device, relates to the technical field of mechanical equipment, solves the problem that in the prior art, a plate cannot be positioned when the plate suddenly stops moving and cannot be prevented from being collided, and comprises a portal crane support frame body, a moving device, a positioning device and a plate body, movable plates are fixedly connected to the two sides of the top of the positioning device, the tops of the movable plates extend into the moving devices, power devices are connected to the two sides of the lower ends of inner cavities of the moving devices through bearings, the number of the movable devices is two, and the bottoms of the two movable devices are connected with abutting devices in an abutting mode; the abutting device is movably connected with the inner wall of the moving device, and the front end and the rear end of the moving device are fixedly connected with the protection devices, so that the overturning angle of the positioning plate is not too large when the positioning plate is overturned, the overall balance of the positioning plate is guaranteed, and the situation that the plate collides with a stop point due to large-amplitude shaking is prevented.

    本发明公开了一种具有防碰撞装置的门式起重机,涉及机械设备技术领域,解决了现有技术中提出的无法对板材移动后突然停止运动进行定位,防止板材碰撞,包括门式起重支持架本体、移动装置、定位装置和板材本体,所述定位装置顶部的两侧均固定连接有活动板,所述活动板的顶部延伸至移动装置的内部,所述移动装置内腔下端的两侧均轴承连接有动力装置,所述活动装置设置有两组,两组所述活动装置的底部均抵触连接有抵触装置,所述抵触装置与移动装置的内壁活动连接,所述移动装置的前后两端均固定连接有防护装置,导致定位板在翻转时翻转角度不会过大,进而保证定位板整体的平衡性,防止因大幅度晃动导致板材与停靠点相碰撞。
