The invention relates to an anti-back-tipping crane. The anti-back-tipping crane comprises a control room fixedly mounted in the middle of the top of a mobile vehicle; the first sliding sleeve shell is fixedly installed on the left side edge of the top of the moving trolley; the balancing weight is connected to the inner side wall surface of the sliding sleeve shell in a sliding and sleeving manner; the threaded groove holes are formed in the surface of the top of the balancing weight and located in the edges of the two sides; the outer side surface of the top of the first sliding sleeve shell is slidably sleeved with a bidirectional sliding unit. Pushing clamping tooth discs rotate through second motors at the two ends of a second sliding sleeve shell, the two pushing clamping tooth discs are in butt joint in different interiors, the pushing clamping tooth discs slide on the inner side wall face of a transmission rail, when the pushing clamping tooth discs rotate, an attaching plate on the surface of one side of a swing arm is matched with the pushing clamping tooth discs to be attached to the vertical face, and therefore the pushing clamping tooth discs are attached to the vertical face. And the swinging arm can extrude the vertical surface at a relatively horizontal angle to support the vertical surface, and the clamping tooth disc is pushed to rotate.
本发明涉及一种防后倾起重机,包括:固定安装在移动车顶部中间位置上的控制室;固定安装在移动车顶部左侧边缘位置上的滑动套壳一;滑动套接在滑动套壳一内侧壁面上的配重块;开设在配重块顶部表面且位于两侧边缘位置上的螺纹槽孔;所述滑动套壳一的顶部外侧表面上滑动套接有双向滑动单元。本发明通过滑动套壳二两端上的电机二对推动卡齿盘进行转动,两个推动卡齿盘对接在不同的内部,使其在传动轨道的内侧壁面上进行滑动,当推动卡齿盘在进行转动的时候,配合摆动臂一侧表面上的贴合板贴合到竖立的一面上,增加贴合力,而摆动臂会以较为水平的角度挤压在的竖立面上进行支撑,在推动卡齿盘的转动下。
