The invention discloses a high-altitude anti-wind device for a crane. The device comprises a mounting cavity and a shell, the top of the shell is fixedly provided with an electric motor through a cover plate, the output end of the electric motor is rotatably provided with an adjusting screw rod extending into the shell, the bottom of the shell is fixedly provided with a mounting cavity, the bottomof the adjusting screw rod is fixedly provided with transmission pieces extending out of the mounting cavity through a mounting block, the center positions of the transmission pieces are movably connected through a second connecting piece, and friction pieces are movably mounted on the bottoms of the transmission pieces. Through the electric motor, the adjusting screw rod, the transmission pieces, and the friction pieces, the device can achieve the automation brake effect through power, the brake anti-wind effect of the device can be avoided or reduced, through a stepping motor, a winding roller, a lifting rope and an anchorage block, the device achieves the automatic anchor dropping and brake effect through the anchorage block, the secondary anti-wind effect is achieved, and the condition that due to the single protection work, the work property of the device is reduced can be avoided or reduced.
本发明公开了一种起重机用高空防风装置,包括安装腔体和壳体,所述壳体的顶部通过盖板固定安装有电动机,所述电动机的输出端转动安装有延伸至壳体内的调节螺杆,所述壳体的底部固定安装有安装腔体,所述调节螺杆的底部通过安装块固定安装有延伸出安装腔体的传动片,且传动片的中央位置处通过第二连接片活动连接,所述传动片的底部活动安装有摩擦片。本发明设置的电动机、调节螺杆、传动片、摩擦片使装置可以通过电力实现了自动化制动的效果,避免或减少装置的制动防风效果,步进电机、卷收辊、吊绳与锚定块使装置可以通过锚定块实现了自动抛锚制动的效果,实现二次防风的效果,避免或减少因单式的防护作业导致装置作业性能降低的情况。
