The Blade Gantry Transfer Vehicle plays a key role in the logistics of wind turbine blades. Accurately grasping and transporting blades of different specifications is the core task to ensure efficient and safe operation.
First, designing an adjustable grasping mechanism is the basis. The grasping device of the transfer vehicle should have multi-dimensional adjustment functions, such as a hydraulically or electrically driven mechanical arm whose length can be extended to adapt to blades of different lengths; the spacing of the mechanical arm's grippers can be adjusted to meet the grasping requirements of blades of different widths; and the opening and closing angles and strength of the grippers can also be precisely controlled, so that the blades can be firmly grasped without causing damage to them. When facing large megawatt-level blades and small blades, by adjusting these parameters, the grasping mechanism can closely fit the blade contour to ensure accurate grasping.
Secondly, use advanced sensing and measurement technology. Equip the grasping mechanism with high-precision sensors, such as pressure sensors, displacement sensors and visual recognition systems. The pressure sensor monitors the contact pressure between the gripper and the blade in real time to ensure that the grasping force is uniform and stable, preventing the blade from slipping or being damaged due to excessive squeezing. The displacement sensor accurately measures the position and posture information of the blade, and the visual recognition system scans and analyzes the appearance characteristics of the blade. Through data processing, the key parameters such as the center of gravity, length, and curvature of the blade are determined, providing accurate data support for the control system of the transfer vehicle, so that the posture and motion trajectory can be adjusted in real time during the handling process to achieve accurate positioning and handling.
In addition, an intelligent control system is developed. The system uses advanced algorithms for calculations and decisions based on the data fed back by the sensor. When faced with blades of different specifications, it can automatically generate an adaptive grasping and handling scheme to control the various moving parts of the transfer vehicle to work together. For example, during the handling process, the driving speed, lifting height, and steering angle of the transfer vehicle are automatically adjusted according to the weight and length of the blade to ensure that the blade is always in a stable and safe state. At the same time, the intelligent control system also has fault diagnosis and early warning functions. Once an abnormal situation is found during the grasping or handling process, such as sensor failure, excessive blade displacement deviation, etc., it can promptly issue an alarm and take corresponding emergency measures to ensure the safety of the operation.
Finally, simulation and actual test optimization are carried out. During the design and development phase of the transfer vehicle, computer simulation software was used to simulate the grabbing and handling process of blades of different specifications in order to identify potential problems in advance and optimize the design. Before and during actual use, a large number of tests were conducted on various actual working conditions and blades of different specifications, data was collected and analyzed, and the parameters of the grabbing mechanism were continuously adjusted, and the algorithms of the sensing and control systems were optimized, so that the grabbing and handling methods of the transfer vehicle for blades of different specifications are more accurate, efficient, and reliable, in order to meet the needs of the ever-evolving wind power industry.
