The invention relates to the technical field of portal cranes, in particular to a dynamic windproof auxiliary device of a portal crane. The invention provides a dynamic windproof auxiliary device of a portal crane, which can automatically keep balance in the center. The invention discloses a dynamic windproof auxiliary device of a portal crane. The dynamic windproof auxiliary device comprises a bottom plate, the sliding rails are connected to the left side and the right side of the top of the bottom plate; the sliding blocks are connected to the interiors of the two sliding rails in a sliding manner; the tops of the two sliding blocks are connected with the main frame body; and the positioning mechanism is connected between the bottom plate and the main frame body. The motor is started to drive the winding wheel to wind the steel rope, the main frame body is driven to move to the middle of the bottom plate under the action of the positioning pile, a worker is prevented from approaching the main frame body in a close range in strong wind, the main frame body is prevented from accidentally turning over to hurt the worker, the safety is high, meanwhile, the weights of the front side and the rear side of the main frame body are balanced, and the working efficiency is improved. The situation that the rear part is heavy and the front part is light or the front part is heavy and the rear part is light is avoided.
本发明涉及门式起重机技术领域,尤其涉及一种门式起重机的动态防风辅助装置。本发明提供一种能够自动居中保持平衡的门式起重机的动态防风辅助装置。一种门式起重机的动态防风辅助装置,包括有底板;滑轨,底板顶部左右两侧均连接有滑轨;滑块,两个滑轨内部均滑动式连接有滑块;主框体,两个滑块顶部连接有主框体;定位机构,底板与主框体之间连接有定位机构。本发明通过启动电机,带动绕线轮对钢绳进行收卷,在定位桩的作用下,带动主框体移动至底板中部,避免工作人员在强风中近距离靠近主框体,防止主框体意外侧翻砸伤工作人员,安全性较高,同时使得主框体前后两侧的重量均衡,不会出现后重前轻或者前重后轻的情况,稳定性较好。
