The invention discloses a limit control system of a crane, and relates to the technical field of cranes, the limit control system comprises a base, the top of the base is fixedly connected with a vertical support, the top of the vertical support is fixedly connected with a transverse support, the transverse support is slidably connected with a U-shaped plate in a penetrating manner, and the bottom of the U-shaped plate is fixedly connected with an anti-collision plate; a displacement sensor is fixedly connected to the bottom of the anti-collision plate, a mounting frame is further fixedly connected to the top of the transverse support, a first electric cylinder and a PLC are fixedly mounted on the mounting frame, the U-shaped plate is driven by the first electric cylinder, and the first electric cylinder and the displacement sensor are both electrically connected with the PLC. When the displacement sensor detects that the distance between the anti-collision plate and the top of the hook is small, the first electric cylinder drives the U-shaped plate and the anti-collision plate to move downwards together, so that the hook is prevented from continuing to move upwards and colliding with the bottom of the transverse support.
本发明公开了一种起重机的限位控制系统,涉及起重机技术领域,包括底座,所述底座的顶部固接有竖向支架,所述竖向支架的顶部固接有横向支架,所述横向支架上贯穿且滑动连接有U形板,所述U形板的底部固接有防撞板,所述防撞板的底部固接有位移传感器,所述横向支架的顶部还固接有安装架,所述安装架上固定安装有第一电缸和PLC控制器,所述U形板通过第一电缸驱动,所述第一电缸和位移传感器均与PLC控制器电性连接;当位移传感器检测到防撞板与挂钩顶部之间的距离较小时,通过使得第一电缸带动U形板和防撞板一起向下运动,以避免挂钩继续向上运动,与横向支架底部进行碰撞。
