The invention relates to an outdoor anti-swing portal crane. In the prior art, the extension length of a mooring rope is long, in the hoisting and transferring process, heavy objects shake, the unhooking condition is caused, and the use safety of a portal crane is reduced. The device comprises a transverse frame (1), the lower end of the transverse frame is slidably connected with a hoisting mechanism (2), the lower end of the hoisting mechanism is slidably connected to the middle of a supporting mechanism (3), the two sides of the supporting mechanism are fixedly connected with limiting mechanisms (6), and the lower ends of the limiting mechanisms are fixedly provided with adjusting mechanisms (4) through bolts; universal wheels (7) are fixedly mounted on the front side and the rear side of the lower end of the tripod mechanism; the supporting mechanism comprises a limiting barrel (31), the two inner sides of the limiting barrel are both slidably connected with limiting sliding rods (32), and the peripheries of the ends, away from each other, of the limiting sliding rods are both sleeved with limiting springs (33). The invention is used for the outdoor anti-swing portal crane.

    本发明涉及一种户外防摇摆门式起重机。现有技术缆绳延伸的长度较长,在吊装转移中,重物出现晃动,造成脱钩情况发生,降低了门式起重机的使用安全性。本发明组成包括:横架(1),横架的下端滑动连接吊装机构(2),吊装机构的下端滑动连接在支撑机构(3)的中部,支撑机构的两侧均固定连接有限位机构(6),限位机构的下端均通过螺栓固定安装有调节机构(4),调节机构的外周均滑动连接在三角架机构(5)的内周三角架机构的下端前后侧均固定安装有万向轮(7);支撑机构包括限位筒(31),限位筒的内两侧均滑动连接有限位滑杆(32),限位滑杆相远离的一端外周均套设有限位弹簧(33)。本发明用于户外防摇摆门式起重机。
