The invention relates to the technical field of cranes, and discloses an automatic anti-overturning crane device which comprises a rotating base, a vertical rod is fixedly connected to the right side of the top of the rotating base, a moving block is slidably connected to the middle of the vertical rod, and a first sliding groove and a second sliding groove are sequentially formed in the front side and the rear side of the top of the rotating base; a second rack sliding block is slidably connected into the first sliding groove, a first rack sliding block is slidably connected into the second sliding groove, and a gear is rotatably connected to the middle of the upper side of the rotating base. Under the action of the gravity of a lifted weight, the sliding plate rotates around a hinge point with the vertical rod, the moving block slides downwards to slide leftwards in cooperation with the first rack sliding block, the second rack sliding block is driven to slide rightwards under the action of the gear, and the sliding plate is pulled downwards to be in a horizontal state through the pulling force of the third connecting rod, so that the crane is prevented from overturning; and the sliding base and the sliding plate are adjusted in a relative sliding manner so as to adapt to different hoisting objects.

    本发明涉及起重机技术领域,公开了一种自动防倾覆起重机装置,包括旋转底座,所述旋转底座的顶部右侧固定连接有竖杆,所述竖杆的中部滑动连接有移动块,所述旋转底座的顶部前后侧依次设置有第一滑槽和第二滑槽,所述第一滑槽的内部滑动连接有第二齿条滑块,所述第二滑槽的内部滑动连接有第一齿条滑块,所述旋转底座的上侧中部转动连接有齿轮。通过起吊重物重力的作用,滑板绕着与竖杆的铰接点转动,移动块向下滑动,配合第一齿条滑块往左侧滑动,在齿轮的作用下带动第二齿条滑块往右侧滑动,第三连杆的拉力把滑板向下拉回水平状态,从而防止起重机倾覆,并且通过滑动底座与滑板相对滑动调节,以便适应不同的吊重物体。
