The invention discloses a large-span bridge diagonal draw bar deicing device which comprises an eccentric rod, a bottom rotating disc, a spiral feeding rotating disc, an icebreaking sleeve, a center mounting sleeve, a mounting bracket, a top sleeve, a stabilizing roller unit and a fastening bolt, and the spiral feeding rotating disc, the icebreaking sleeve, the center mounting sleeve and the top sleeve are sequentially mounted based on the bottom rotating disc; an icebreaking sleeve is installed on the installation support in a positioning mode, the icebreaking sleeve conducts icebreaking treatment on a bridge steel cable, and the stabilizing roller unit supports the bridge steel cable to ensure that the whole device stably slides downwards. The large-span bridge diagonal draw bar deicing device is installed at the top of the steel cable, and the spiral feeding rotary disc makes contact with the bridge steel cable. The whole device is driven to rotate by the convex pattern characteristic of the worm when the device slides downwards in an inclined mode, unpowered self-rotating deicing design is achieved, the eccentric rod is subjected to centrifugal force and inertia force, the swing amplitude of the eccentric rod is guaranteed, then the whole device is driven to rotate, ice and snow broken by the circular-truncated-cone-shaped cylinder are dispersed and guided through the design of the ice breaking shovel, and ice and snow blockage is avoided.
本发明公开了一种大跨度桥梁斜拉杆除冰装置，包括偏心杆、底转盘、螺旋进给转盘、破冰套筒、中心安装套筒、安装支架、顶部套筒、稳定辊单元、紧固螺栓，基于底转盘顺序安装有螺旋进给转盘、破冰套筒、中心安装套筒和顶部套筒，安装支架定位安装有破冰套筒，破冰套筒对大桥钢缆进行破冰处理，稳定辊单元支撑大桥钢缆保证整个装置稳定下滑运动，一种大跨度桥梁斜拉杆除冰装置，装置安装在钢缆顶部，螺旋进给转盘与大桥钢缆接触，装置倾斜下滑蜗杆凸纹特性带动整个装置转动，实现了无动力自旋转除冰设计，偏心杆受离心力和惯性力保证了偏心杆的摆动幅度进而带动整个装置转动，破冰铲的设计将圆台型筒体破碎的冰雪进行分散导流，避免冰雪堵塞。
