The invention relates to the technical field of engineering machinery, in particular to a superlift automatic tensioning control method and device, engineering machinery and a storage medium. Comprising the following steps: controlling a superlift device to carry out superlift automatic tensioning; determining whether the boom has a first deflection according to the head inclination angle, the root inclination angle and the middle inclination angle; under the condition that the boom does not have the first deflection, the overall sidewise bending amount of the boom is determined; under the condition that the overall sidewise bending amount is larger than the preset maximum sidewise bending amount, sidewise bending adjustment is conducted; under the condition that the overall sidewise bending amount is smaller than or equal to the preset maximum sidewise bending amount, the overall maximum deflection of the cantilever crane is determined according to the head inclination angle and the root inclination angle; under the condition that the overall maximum deflection is larger than the preset maximum deflection, deflection adjustment is conducted; and under the condition that the overall maximum deflection is smaller than or equal to the preset maximum deflection, it is determined that superlift automatic tensioning is completed, the sidewise bending and deflection adjusting efficiency of the arm frame is improved, the tensioning effect is improved, tensioning is more comprehensive, and the safety of the arm frame is improved.

    本申请涉及工程机械技术领域,尤其是一种超起自动张紧的控制方法、装置、工程机械及存储介质。包括:控制超起装置进行超起自动张紧;根据头部倾角、根部倾角以及中部倾角确定臂架是否出现第一挠度;在臂架未出现第一挠度的情况下,确定臂架的整体旁弯量;在整体旁弯量大于预设最大旁弯量的情况下,进行旁弯调节;在整体旁弯量小于或等于预设最大旁弯量的情况下,根据头部倾角和根部倾角确定臂架的整体最大挠度;在整体最大挠度大于预设最大挠度的情况下,进行挠度调节;在整体最大挠度小于或等于预设最大挠度的情况下,确定超起自动张紧完成,提高对臂架的旁弯和挠度的调节效率,提高张紧效果,使得张紧更为全面,提升臂架安全性。
