Method for controlling working track of aerial work platform

Abstract

The invention discloses a method for controlling a working track of an aerial work platform and belongs to the technical field of aerial work platform control. The method comprises the following concrete steps: (1) presetting a working surface, vertically placing a working arm on the working surface, recording an initial arm length, an elevation angle and a revolution angle of the working arm, and then calculating the position of the working surface; (2) performing data operation and logic treatment, and reading the arm length, the elevation angle and the revolution angle of the working arm; (3) acquiring the arm length, the elevation angle and the revolution angle of the working arm; (4) calculating the actually required arm length, elevation angle and revolution angle of the working arm; (5) calculating the arm length and the elevation angle of the working arm needed to be compensated at any revolution angle; and (6) outputting a PWM (pulse width modulation) value by a solenoid valve which controls the stretching and amplitude, thereby realizing the error compensation. The method provided by the invention has the beneficial effects that the motion on the whole working surface is realized, the trouble in frequently positioning in the operation process is reduced, the working process is smoother, safer and more reliable, and the collision accident is reduced.

[0002] With the development of social economy, the scale of urban construction is also constantly expanding. At the same time, the workload of building cleaning and maintenance will become larger and larger, and the application of aerial work platforms will become more and more extensive. With the widespread use of aerial work vehicles application, how to improve its work rate has become the focus of research. The original aerial work platform must be equipped with operators or staff to operate while working, which affects work efficiency and consumes a lot of manpower and material resources.

[0003] In order to improve the working efficiency of the aerial work platform and reduce labor costs, the aerial work platform has been continuously improved, so that the aerial work platform can operate automatically, and the staff only need to stand on the work platform to work. In recent years, many aerial work platforms The platform has begun to use vertical lifting to realize intelligent control. The realization method is to use the variable amplitude as the main variable, and the expansion and contraction as the secondary variable, so that the amplitude remains unchanged during the overall operation process. Without the participation of turning action, only the action in the vertical direction can be realized, but the action in the horizontal direction cannot be realized, and then the action on the entire working surface cannot be formed. It is still necessary to manually adjust the horizontal position of the aerial work platform to complete The work on the entire working surface, so that the overall work efficiency is still not high
