The invention discloses a bridge crane lifting protection structure, and relates to the technical field of cranes, the bridge crane lifting protection structure comprises a portal frame, a top seat is fixedly arranged at the top of the portal frame, first grooves are formed in the two ends of the top seat, and sliding rods are fixedly arranged on the surfaces of the inner walls of the first grooves; an object is hung at the bottom of a fixing column, then a pulley in a lifting device rotates to drive a connecting plate and the object to move towards the top of a portal frame together, when the object moves upwards, a connecting rod rotates, and the connecting rod pushes a first fixing seat and a sliding block to move towards the two ends of a sliding rod; when the height of the object reaches a certain value, the sliding blocks can reach the two ends of the sliding rod, so that the connecting plate cannot continue to ascend, the ascending of the connecting plate is limited, meanwhile, through the arrangement of the connecting rod, the object is prevented from being in a shaking state during ascending, and the stability of the object during ascending is improved.
本发明公开了一种桥式起重机起升防护结构,涉及起重机技术领域,包括龙门架,所述龙门架的顶部固定设置有顶座,所述顶座的两端均开设有第一凹槽,所述第一凹槽的内壁表面固定设置有滑杆;本发明通过将物件挂接在固定柱的底部,接着通过起升装置内部的滑轮转动,带动着连接板与物件一起向着龙门架的顶部进行运动,在物件向上运动时,连杆会进行转动,并且连杆将会推动着第一固定座以及滑块向着滑杆的两端进行移动,当物件的高度达到一定时,滑块将会到达滑杆的两端从而使得连接板不会在继续上升,以此对连接板的上升起到限位的作用,同时,通过连杆的设置,避免了物件在上升时处于摇晃的状态,增加了物件上升时的稳定性。
