The invention relates to a single-beam portal crane which comprises a main beam, an electric hoist is movably installed at the bottom of the main beam, supporting legs are installed on the two sides of the two ends of the main beam, the supporting legs are movably connected with the main beam through upper hinged supports, ground beams are installed at the bottoms of the supporting legs, and the supporting legs are movably connected with the ground beams through lower hinged supports. Walking mechanisms are mounted on the ground beams, and the ground beams at the bottoms of the supporting legs on the two sides of the main beam are fixedly connected through fasteners and bolts. According to the single-beam portal crane, the upper ends and the lower ends of the supporting legs are connected with the main beam and the ground beam through the upper hinged supports and the lower hinged supports correspondingly, the supporting legs and the ground beam are movably connected, the walking mechanisms of the ground beam can push the bottoms of the supporting legs to move inwards during hoisting, and meanwhile a certain supporting effect is achieved on the supporting legs and the main beam; and the main beam, the supporting legs and the ground beam are connected into a whole before hoisting, so that hoisting is convenient, the whole is convenient to assemble, and operation is convenient.

    本发明涉及一种单梁门式起重机,包括主梁,所述主梁的底部活动安装有电动葫芦,所述主梁两端的两侧安装有支腿,所述支腿与主梁通过上铰座活动连接,所述支腿的底部安装有地梁,所述支腿与地梁通过下铰座活动连接,所述地梁上安装有行走机构,所述主梁两侧所述支腿底部的所述地梁通过扣件及螺栓固定连接。本发明一种单梁门式起重机,通过支腿的上下两端分别通过上铰座及下铰座与主梁及地梁连接,支腿及地梁都为活动连接,在吊装时地梁的行走机构可推动支腿的底部向内移动,同时对支腿及主梁起到一定的支撑作用,且吊装前将主梁、支腿及地梁连接为一体,便于起吊、便于对整体进行组装,方便操作。
