The invention relates to the technical field of hoisting equipment, and provides an anti-rollover device of a crane and the crane, the anti-rollover device comprises a base and a cross rod, the top of the base is provided with a bracket, the bottom of the cross rod is fixedly provided with a rack, the inner wall of the bracket is rotatably provided with a rotating shaft, and the outer surface of the rotating shaft is fixedly provided with a hydraulic rod; a second gear is fixedly installed at the telescopic end of the hydraulic rod, and the hydraulic rod and the second gear are distributed in an inclined mode. According to the rollover prevention device, the first gear and the supporting box on the other side lose supporting on the transverse rod under the action of the second gear, so that supporting points at the bottom of the transverse rod are changed into the movable second gear, the fixed first gear and the fixed supporting box, and the position of the second gear at the bottom of the transverse rod is adjusted; and two supporting points at the bottom of the cross rod are always symmetrically distributed on the two sides of the electric hoist, so that the stress balance of the cross rod is kept, and the device is prevented from tipping over.
本发明涉及起重设备技术领域,提出了一种起重机的防倾翻装置及起重机,包括底座和横杆,所述底座的顶部安装有支架,所述横杆的底部固定安装有齿条,所述支架的内壁转动安装有转轴,所述转轴的外表面固定安装有液压杆,所述液压杆的伸缩端固定安装有齿轮二,所述液压杆和齿轮二呈倾斜分布。本防倾翻装置经过另一侧的齿轮一和支撑盒在齿轮二的作用下失去对横杆的支撑,从而使横杆底部的支撑点变为可以移动的齿轮二和固定不动的齿轮一、支撑盒,通过调节齿轮二在横杆底部的位置,使横杆底部的两个支撑点始终对称分布于电动葫芦的两侧,从而保持横杆的受力平衡,避免装置发生倾翻。
