The invention relates to the technical field of overhang cranes, in particular to an anti-overturning overhang crane. The invention provides an anti-overturning suspension crane which can adjust the length and the height so as to adapt to the deviation condition of a beam frame. The anti-overturning suspension crane comprises a crane body, a supporting column, a sliding ring, a supporting block and the like, supporting columns are connected to the left and right parts of the crane body, sliding rings are slidably connected to the lower parts of the supporting columns, and a plurality of supporting blocks are slidably connected to the lower parts of the supporting columns. The supporting columns can support the left portion and the right portion of the crane body, the supporting blocks slide outwards to expand to increase the ground contact area of the supporting columns, the anti-overturning effect is achieved, and the electric push rods extend to drive the lifting plates to move outwards to prolong the length of the crane body so as to adapt to distance deviation of the supporting beam frames on the two sides. And the screw rod rotates and is matched with the nut to adjust the height of the lifting plate so as to adapt to the height deviation of the supporting beam frames on the two sides and ensure that the crane body can be horizontally hung on the beam frames.
本发明涉及悬挂起重机技术领域,尤其涉及一种防倾覆悬挂起重机。本发明提供一种能够调节长度以及高度,以适应梁架偏差情况的防倾覆悬挂起重机。一种防倾覆悬挂起重机,包括有起重机本体、支撑柱、滑动环和支撑块等;起重机本体左右两部均连接有支撑柱,支撑柱下部均滑动式连接有滑动环,支撑柱下部均滑动式连接有若干个支撑块。支撑柱可对起重机本体左右两部进行支撑,支撑块向外滑动张开增加支撑柱触地面积,起到防倾覆的作用,电动推杆伸长带动升降板向外移动延长起重机本体的长度,以适应两侧支撑梁架的距离偏差,而丝杆转动与螺母配合可调节升降板高度,以适应两侧支撑梁架的高低偏差,确保起重机本体可水平挂靠在梁架上。
