The invention provides a tilting rotating system and a crane and relates to the technical field of the cranes. The tilting rotating system comprises a controller, stretching and contracting cylindersand a position-limiting component, wherein the stretching and contracting cylinders are internally provided with displacement sensors, the displacement sensors are used for detecting the stretching and contracting quantity of the stretching and contracting cylinders, and the stretching and contracting cylinders, the position-limiting component and the displacement sensors are all connected with the controller; the position-limiting component comprises a front stopping position-limiting mechanism and a rear stopping position-limiting mechanism, furthermore, the front stopping position-limitingmechanism and the rear stopping position-limiting mechanism are located at the side portions of the stretching and contracting cylinders, and the connecting line direction of the front stopping position-limiting mechanism and the rear stopping position-limiting mechanism is consistent with the stretching and contracting sirection of the stretching and contracting cylinders; and the controller is used for receiving tilting rotating command signals and displacement sensor signals, the controller is used for controlling the multiple stretching and contracting cylinders to move according to the tilting rotating command signals when the displacement sensor signals are not within a preset range, and the controller controls the stretching and contracting cylinders to stop moving when the tiltingrotating command signals are cancelled or trigger portions of the stretching and contracting cylinders trigger the front stopping position-limiting mechanism or the rear stopping position-limiting mechanism.
本发明提供了一种倾转系统及起重机,涉及起重机技术领域,倾转系统包括:控制器、伸缩缸、限位组件,伸缩缸内设置有位移传感器,位移传感器用于检测伸缩缸的伸缩量,伸缩缸、限位组件和位移传感器均与控制器连接;限位组件包括前停止限位机构和后停止限位机构,且前停止限位机构和后停止限位机构位于伸缩缸的侧方,且前停止限位机构和后停止限位机构的连线方向与伸缩缸的伸缩方向一致;控制器用于接收倾转指令信号和位移传感器信号;当位移传感器信号不在预设范围内时,控制器用于控制多个伸缩缸按照倾转指令信号运动;当倾转指令信号取消,或伸缩缸的触发部触发前停止限位机构或者后停止限位机构时,控制器控制伸缩缸停止运动。
