The invention relates to the technical field of cranes, in particular to an anti-collision device for a gantry of a gantry crane, which is provided with an outer protection component, an inner protection component, a fixing frame, a mounting frame, an audible and visual alarm and a switch, when a gantry main body is collided, a buffer block in the outer protection component arranged in the mounting frame shrinks towards the inside of a cylindrical roller, so that the gantry main body is prevented from being collided; then the cylindrical roller and the outer protection assembly in the cylindrical roller buffer impact force generated by collision, meanwhile, the cylindrical roller rotates in the mounting frame, then the mounting frame shrinks towards the interior of the fixing frame, the inner protection assembly in the fixing frame buffers impact force generated by collision of the portal frame body again, and therefore the portal frame body of the portal crane can be protected conveniently; when the buffer rod in the cylindrical roller drives the driving block to move, the driving block presses the switch in the buffer block, then the switch turns on the audible and visual alarm on the fixing frame, the audible and visual alarm gives an audible and visual alarm, and the warning to workers is improved.
本发明涉及起重机技术领域,更具体地说,本发明提供了一种门座式起重机门架防撞装置,通过设置的外护组件、内护组件、固定架、安装架、声光报警器和开关,当门架主体受到碰撞时,安装架内设置的外护组件中的缓冲块向圆柱辊内收缩,然后圆柱辊及其内部的外护组件将碰撞产生的冲击力进行缓冲,同时圆柱辊在安装架内转动,然后安装架向固定架内收缩,固定架中的内护组件将碰撞门架主体产生的冲击力再次缓冲,从而便于对门座式起重机的门架主体进行保护;圆柱辊内部的缓冲杆带动驱动块移动时,驱动块压动缓冲块中的开关,随后开关将固定架上的声光报警器打开,声光报警器进行声光警报,提高对工作人员进行警示。
