The invention provides a method, device and facility for controlling operation driving force of an overhead crane and a readable storage medium. The method comprises the steps that the current operation speed of an overhead crane hoisting lifting appliance, the current operation speed of an overhead crane large structural part and the current dragging torque of a hoisting motor are obtained; the current acceleration of the overhead crane hoisting lifting appliance is calculated according to the current operation speed of the overhead crane hoisting lifting appliance; the weight of an object lifted by the overhead crane hoisting lifting appliance is determined according to the current operation speed and the current acceleration of the overhead crane hoisting lifting appliance and the current dragging torque of the hoisting motor; a current rolling resistance coefficient of an overhead crane track is determined; current operation driving force of the overhead crane large structural partis determined according to the current rolling resistance coefficient, the weight of the object and the current operation speed of the overhead crane large structural part; and the operation drivingforce of the overhead crane large structural part is adjusted to be the current driving force. The driving force of the overhead crane can be adjusted according to the resistance and mass changes in the operation process of the overhead crane, so that the overhead crane is more stable in the operation process.
Description
technical field [0001] The present invention relates to the technical field of hoisting equipment, in particular to a method, device, equipment and readable storage medium for controlling the driving force of a crane operation. Background technique [0002] Cranes are widely used in industrial sites, especially in the non-ferrous metal smelting industry, which relies heavily on cranes. Although the running speed of the crane has been improved, the crane often vibrates violently during operation, and the operation is not stable enough. [0003] In the non-ferrous metal smelting workshop, because the sulfuric acid solution is often put into the smelting pool, which has strong volatility, when it encounters the crane track, it will condense on the track and have a certain corrosion effect on the track, which causes the track The drag coefficient of the crane changes at different positions; and when the crane is lifting different objects, the quality of the objects is different...
