Background technique

Most of the suspended equipment is the operating mechanism of the main equipment of the power grid, and the quality of its installation process directly affects the healthy operation of the equipment. For example, the improper installation position of the mechanism box of the isolating switch will cause the main shaft of the isolating switch to bear radial stress. When the motor rotates, it will generate a torque on the main shaft, which will cause plasticity of the main shaft or other weak transmission parts after long-term operation. out of shape. As a result, the opening and closing operations of the isolating switch are not in place and the fixing parts at both ends of the main shaft are worn out, which will endanger the safe operation of the equipment. Taking Quanzhou Electric Power Bureau as an example, from 2006 to 2010, 261.8 sets of isolating switches were added every year; 2,000 sets of isolating switches in operation, the maximum operating life of the knife switch is 20 years, and the average annual number of technical transformation and replacement is 100 sets, so every year About 361.8 sets of isolating switches need to be installed, which is an important part of a maintenance work. As the power source of the isolating switch, the installation process of the mechanism box directly affects the healthy operation of the equipment. At present, there are many ways to install the operating mechanism of the isolating switch, and each construction team does not have a standard. There are wooden boxes under the mechanism box, hydraulic forklifts and various plugging objects to fix it; the mechanism box is hung on the main shaft of the isolating switch with a rope. On, and then artificially corrected and so on. These installation methods cannot accurately meet the installation accuracy of the mechanism box in the three axial positions of the space, and have a low safety factor, easy damage to equipment components, cumbersome installation procedures, low work efficiency, and waste of manpower and material resources.

The stepping motor driver is a dual-axis stepping motor driver, and one stepping motor driver drives the stepping motors in the two supporting legs to move.

The method for the single-chip microcomputer to control the action of the stepping motor is to adjust the highest support point of the panel in a chasing and leveling manner in which the other three support points are aligned to it.

The specific adjustment method of the outriggers is to use the leveling method of raising the outriggers in one direction, that is, the highest point of the platform is not determined, and the method of leveling in the order of the X direction and the Y direction is used. When leveling, only adjust The lower side in each direction, specifically, adjust the level of the X direction first, and judge the inclination angle α measured by the level sensor of the dual-axis inclination sensor.

The described leveling method is that the X direction and the Y direction are repeatedly adjusted repeatedly.

With the above leveling method, even if there is interference or the highest point of the platform changes due to coupling, the purpose of leveling can be achieved through unidirectional quadratic adjustment. The one-way raising outrigger leveling strategy is actually an improvement of the chasing method. This leveling method strictly follows the principle that the outriggers only rise but not lower during the leveling process, ensuring the stability and accuracy of the leveling , while effectively eliminating coupling and interference during the leveling process. This method avoids the disadvantages that the displacement and speed of each leg are different during multi-point adjustment, thereby restricting each other, and the specific control algorithm is difficult to implement. At the same time, it does not need to find the highest point, which reduces the system running time and programming workload.

The work flow of the control system is as follows: firstly perform four virtual leg detections, if the detection is not completed, continue the detection, if the detection is completed, set the Z-axis height, if it reaches the first position, continue to perform X-axis calibration, if not continue to perform Z-axis Axis setting, if the X-axis calibration meets the accuracy, continue to calibrate the Y-axis, if the X-axis is not calibrated, continue to perform the X-axis calibration, if the Y-axis calibration meets the accuracy, the work is completed, and the Z-axis resets.
