The invention discloses a control method, a device, a medium and a crane for the positioning of lifting equipment. The control method includes: the control device acquires the first target height that the cage of the lifting device needs to reach; the control device controls the cage to move upward or downward according to the first target height; the control device sends a parking signal so that the cage is at the second Stop at the position of the target height; the control device sends out a slow down signal, so that one end of the electric push rod of the cage is extended, and the cage is moved to a position matching the first target height. The crane adopts the control method to realize the lifting operation of the heavy objects, and the control device is used to execute the control method. The implementation of the present invention is beneficial to the accuracy of the positioning of the heavy objects to be lifted, thereby improving the working efficiency of the lifting equipment and making the lifting equipment applicable to the application scene.
Description
Technical field [0001] The present invention relates to the field of control technology, and more particularly to a control method for lifting equipment positioning, a crane and a control device using the method. Background technique [0002] For a lifting device provided with a winder, the method of detecting the height of the lifting device is mainly to detect the position of the roll rotation of the hoist, convert the position of the reel to the height of the lifting device. [0003] However, in practice, it has been found that the wire rope of the reel requires a multilayer winding to meet the height conditions of the above heavy objects to satisfy the height conditions of the above heavy objects. Through the roll of the roller, the position of the roller is rotated to determine the height of the lifting equipment, the lifting equipment can be smoothly suspended in a multi-layer wire rope, which is not conducive to The accuracy of the weight positioning of the need to increas...
