The cantilever crane with the windproof function comprises a rotating air cylinder, a rotating shaft is fixed to the output end of the rotating air cylinder, a cargo boom is fixed to the top end of the rotating shaft, moving mechanisms are arranged at the two ends of the cargo boom, a hoisting mechanism is arranged below the moving mechanisms, and a hanging mechanism is arranged below the hoisting mechanism. Support adjusting mechanisms are arranged on the two sides of the rotating shaft; the hoisting mechanism comprises a hoisting seat fixed to the threaded seat, openings are formed in the top and the bottom of the hoisting seat in a penetrating mode, a hoisting roller is rotationally connected to the middle of the inner surface of the hoisting seat, auxiliary rollers are arranged on the two sides of the hoisting roller, and a hoisting rope is wound around the outer surface of the hoisting roller; the problems that in the prior art, due to the fact that a heavy object is independently pulled by a strand of steel wire rope, the heavy object is only pulled by upward acting force, the heavy object is prone to shaking under the wind resistance effect, and when the heavy object is large, a crane is prone to inclining are solved.

    本发明涉及一种具有防风功能的悬臂起重机,包括旋转气缸,旋转气缸的输出端固定有旋转轴,旋转轴的顶端固定有起重臂,所述起重臂的两端均设有移动机构,移动机构的下方设有起重机构,起重机构的下方设有悬挂机构,旋转轴的两侧均设有支撑调节机构;所述起重机构包括与螺纹座相固定的起重座,起重座的顶部和底部贯穿设有开口,起重座的内表面中部转动连接有起重辊,起重辊的两侧均设有辅助辊,起重辊的外表面缠绕有起重绳;解决了现有技术中,由于重物单独被一股钢丝绳拉动,使得重物仅仅受到向上的作用力拉动,容易造成重物在风阻作用下产生晃动,并且当重物质量较大时,容易造成起重机的倾斜等问题。
