The invention relates to the field of fabricated construction hoisting, in particular to a small anti-collapse electric door-shaped crane which comprises rails, a door-shaped hanging bracket and an anti-collapse support, the rails are located on the two sides of a car inspection pit, and the door-shaped hanging bracket is arranged on the rails in a striding mode and can slide along the rails. The door-shaped hanging bracket comprises a supporting frame connected with the track in a sliding mode and a cross beam used for installing a hoisting assembly. The anti-falling supports are rotationally connected with the supporting frames in a one-to-one correspondence mode, the anti-falling supports are rotated to form included angles with the planes where the supporting frames are located, the lateral movement resisting rigidity of the supporting frames can be improved, and therefore the structural stability of the door-shaped hanging bracket is enhanced. The tie piece is arranged between the supporting frame and the cross beam, the deformation deflection of the cross beam can be reduced, and the stress concentration phenomenon is relieved by increasing stress points of the cross beam. The large-span light hoisting equipment has the effect that the structural stability of the large-span light hoisting equipment is improved so as to meet the hoisting requirement of in-garage vehicle inspection pit construction.
本申请涉及装配式施工吊装的领域,尤其是涉及一种小型防倒塌电动门型吊,包括轨道、门型吊架及防倒支架,轨道位于检车坑两侧,门型吊架跨设于轨道之上且能沿轨道滑动。门型吊架包括与轨道滑动连接的支撑架及用于安装起重组件的横梁。防倒支架与支撑架一一对应转动连接,转动防倒支架至与支撑架所在平面形成夹角,能够提高支撑架的抗侧移刚度,从而增强门型吊架的结构稳定性。支撑架与横梁之间设有拉结件,能够减小横梁的变形挠度,通过增加横梁的受力点,缓解应力集中的现象。本申请具有提高大跨度轻型吊装设备的结构稳定性,以满足库内检车坑施工的吊装需求的效果。
