The invention relates to a high-stability single-stage portal frame. The portal frame comprises two stand columns arranged in parallel, wherein one ends of the two stand columns are jointly and fixedly connected with a base, the ends, away from the base, of the two stand columns are jointly and fixedly connected with an upper beam, the side wall, close to the base, of the upper beam is fixedly connected with cylinder bodies of a plurality of oil lifting hydraulic cylinders, piston rods of the oil lifting hydraulic cylinders are arranged in the length direction of the stand columns, the ends ofthe piston rods of the oil lifting hydraulic cylinders are jointly and fixedly connected with a fork frame body, the side, away from the base, of the bottom of the fork frame body is fixedly connected with a plurality of fork bodies perpendicular to the base and forming included angles of 75-90 degrees with the stand columns, a stiffening beam is fixedly connected to the middles of the two standcolumns jointly, and rotating oil hydraulic cylinders are rotationally connected to the two ends of the stiffening beam correspondingly. The portal frame has the effect of effectively improving the stability of the carrying state.

    本发明涉及一种高稳定性单级门架,其包括两相互平行设置的立柱,两立柱一端共同固定连接有底座,两立柱远离底座的一端共同固定连接有上梁,上梁靠近底座的侧壁上固定连接有多个升油压缸的缸体,升油压缸的活塞杆均沿立柱的长度方向设置,升油压缸的活塞杆端部共同固定连接有叉架体,叉架体底部远离底座的一侧固定连接有多根垂直于底座且与立柱呈75度至90度夹角的叉体;两立柱中部共同固定连接有加强梁,加强梁两端均转动连接有转动油压缸。本发明具有有效提高载物状态稳定性的效果。
