The invention relates to the technical field of cranes, in particular to an intelligent crane based on polar coordinates, a square frame support is fixed to the top of an inner wall of a plant, and a middle seat comprises a disc piece with the top face fixed to the center of a top plate of the plant and a supporting vertical shaft rotationally arranged in the center of the disc piece in a sleeving mode; the rotating rail beam comprises a cylindrical part arranged at the bottom end of the supporting vertical shaft in a sleeving mode and a linear I-shaped beam fixed to the peripheral wall of the cylindrical part in the radial direction, the crane carriage walks along the linear I-shaped beam, a driving assembly moving circumferentially along the top face of an annular supporting rail on the square frame support is fixed to the outer end of the linear I-shaped beam, and the calibration rod is used for calibrating the target position of hoisting operation. The coordinate positioning assembly arranged in the center of the plant bottom plate comprises a laser range finder and an angle sensor, the distance information of the calibration rod measured by the laser range finder controls the walking distance of the crane carriage, and the angle information detected by the angle sensor is used for controlling the angular displacement of the driving assembly; and smooth walking of the crane is realized, and the automation level of hoisting operation is improved.

    本发明涉及起重机技术领域,具体为一种基于极坐标的智能型起重机,方框支架固定于厂房内墙壁顶部,中部座包括顶面固定于厂房顶板中心的圆盘件以及转动套装于圆盘件中心的支撑竖轴,旋转轨梁包括套装于支撑竖轴底端的筒形件以及径向固定于筒形件外周壁的直线工字梁,起重小车沿直线工字梁行走,沿方框支架上的环形支撑轨顶面圆周运动的驱动组件与直线工字梁外端固定,标定杆用于标定起吊作业目标位置,设于厂房底板中心的坐标定位组件包括激光测距仪及角度传感器,激光测距仪测量的标定杆的距离信息控制起重小车的行走距离且角度传感器检测的角度信息用于控制驱动组件的角位移;实现了起重机的平顺行走并提高了起吊作业的自动化水平。
