The invention belongs to the technical field of portal cranes, and particularly relates to a portal crane anti-typhoon fixing structure which comprises a machine body and a groove formed in the ground, a fixing block is fixedly embedded in the middle of the machine body, an opening is formed in the fixing block, and a box is slidably arranged in the opening; telescopic rods are symmetrically arranged on the upper side wall of the machine body, connecting rods are fixedly connected between the driving ends of the telescopic rods and the outer wall of the box body, vertical movement of the box body is achieved through stretching and retracting of the driving ends of the telescopic rods, and a plurality of openings are formed in the lower side wall of the box body. The rotating right-angle plate arranged on the machine body is matched with the groove, the end of the right-angle plate abuts against the inner wall of the groove to complete connection and fixation of the machine body and the groove, the magnetic force of the electromagnet plate is increased through rotation of the rotating plate when a typhoon is encountered, and the friction force of the contact position of the right-angle plate and the inner wall of the groove is increased; the machine body is more stable and not easy to pull up, and the typhoon resistance is improved.
本发明属于门式起重机技术领域,尤其涉及一种门式起重机防台风固定结构,包括机体以及开设在地面上凹槽,所述机体的中部固定嵌设有固定块,所述固定块上开设有开口,所述开口内滑动设置有箱体,所述机体的上侧壁对称设置有伸缩杆,所述伸缩杆的驱动端与箱体的外壁之间固定连接有连杆,通过所述伸缩杆驱动端的伸缩实现箱体的上下移动,所述箱体的下侧壁上开设有多个开口。本发明通过机体上设置转动的直角板与凹槽的配合,通过直角板端部与凹槽内壁的抵紧完成机体与凹槽的连接固定,并在遭遇台风时通过转板的转动使电磁铁板磁力增加,增加直角板与凹槽内壁接触处的摩擦力,使机体更加稳定不易拔起,增加了抗台风能力。
