The invention provides a slewing mechanism, a slewing device, engineering machinery and a slewing control method, and belongs to the technical field of engineering machinery. The swing mechanism comprises a first platform, a second platform, an inductive switch assembly and an assembly to be inducted. The first platform is rotationally connected with the second platform, the inductive switch assembly is arranged on the first platform, the to-be-inducted assembly is arranged on the second platform, the inductive switch assembly comprises a first inductive switch and a second inductive switch, and the to-be-inducted assembly comprises a first limit to-be-inducted part and a second limit to-be-inducted part; the first limit to-be-sensed piece is located on the rotating track of the first sensing switch, and the second limit to-be-sensed piece is located on the rotating track of the second sensing switch. According to the slewing mechanism, the first platform can only rotate in a reciprocating mode between the first limit to-be-sensed piece and the second limit to-be-sensed piece, the rotation angle is limited, and compared with a traditional mode that a rotary encoder is adopted for controlling the rotation angle, the slewing mechanism is lower in cost and higher in reliability.
本发明提供了一种回转机构、回转装置、工程机械及回转控制方法，属于工程机械技术领域。回转机构包括第一平台、第二平台、感应开关组件和待感应组件；第一平台与第二平台转动连接，感应开关组件设置于第一平台上，待感应组件设置于第二平台上，感应开关组件包括第一感应开关和第二感应开关，待感应组件包括第一极限待感应件和第二极限待感应件；第一极限待感应件位于第一感应开关的旋转轨迹上，第二极限待感应件位于第二感应开关的旋转轨迹上。该回转机构实现第一平台只能在第一极限待感应件和第二极限待感应件之间的往复旋转，限定了旋转角度，相比于传统的采用旋转编码器控制旋转角度，本发明的回转机构成本更低，可靠性更高。
