The invention relates to the technical field of cranes, and particularly discloses a gantry crane windproof device which comprises a main beam frame, supporting legs are installed at the positions, close to corners, of the two ends of the bottom of the main beam frame, bottom plates are installed at the bottom ends of the supporting legs located at the two ends of the bottom of the main beam frame, and protective shells are installed on the two sides of the main beam frame. A sliding plate is slidably mounted in the protective shell, the two sides of the sliding plate penetrate through the protective shell, a movable plate is mounted at the top end of the sliding plate, a plurality of flow guide plates are mounted on the side, away from the main beam frame, of the protective shell, and air inlets are formed in the positions, between the adjacent flow guide plates, of the top end of the side face of the protective shell. Air nozzles are formed in the positions, close to corners, of the two ends of the main beam frame. The main beam frame can be pushed to move against the wind direction by the reverse thrust of the air nozzles during air injection, so that the stability of the main beam frame during movement is improved.

    本发明涉及起重机技术领域,具体的公开了一种龙门式起重机防风装置,包括主梁架,所述主梁架的底部两端靠近边角的位置均安装有支腿,位于主梁架底部两端的支腿底端安装有底板,主梁架的两侧均安装有防护壳,防护壳的内部滑动安装有滑动板,滑动板的两侧均贯穿防护壳,滑动板的顶端安装有移动板,防护壳远离主梁架的一侧安装有若干个导流板,防护壳的侧面顶端位于若干个相邻的导流板之间均安装有进气口,主梁架的两端靠近边角的位置均安装有喷气口。本发明喷气口在喷气时的反推力便可推动主梁架向逆风方向进行移动,提升主梁架在移动时的稳定性能。
