Engineering machinery, control device, system and method thereof and machine readable storage medium
The invention relates to the field of engineering machinery, and discloses engineering machinery, a control device, system and method of the engineering machinery and a machine readable storage medium. When the real-time working oil pressure of a hydraulic system controlled by the control device in the engineering machinery is larger than the preset maximum working oil pressure, it is indicated that the current load of the engineering machinery is too large; at the moment, oil can be supplied into an oil cavity of the operating device through an oil port of the operating device, the piston is driven by oil pressure in the oil cavity to axially slide outwards so as to increase the compression amount of the elastic piece, and the counter-acting force of the elastic piece on the operating rod mechanism is increased. The operating lever mechanism axially moves outwards, so that the working power of engineering machinery can be reduced, the pressure building of a hydraulic system is prevented, the load of an engine can be prevented from exceeding the maximum value which can be borne by the engine under the current output power, the engine is prevented from speed reduction or flameout, and the service life of the engine is prolonged; and meanwhile, the control smoothness, comfort and safety can be improved.
本申请涉及工程机械领域，公开了一种工程机械及其操纵装置、系统、方法和机器可读存储介质，当工程机械中由操纵装置操纵的液压系统的实时工作油压大于预设的最大工作油压时，表示工程机械当前遇到的负载过大，此时可通过操纵装置的油口向其油腔内供油，利用油腔中的油压驱动活塞轴向向外滑移以增大弹性件的压缩量，使弹性件对操纵杆机构的反作用力增大，当弹性件反作用力大于原本施加在操纵装置上的操纵力时，操纵杆机构会轴向向外移动，从而能够降低工程机械做功功率，防止液压系统憋压，能够避免发动机负载超出发动机在当前输出功率下所能承受的最大值，防止发动机掉速或熄火，延长发动机寿命，同时还能够提高操纵平顺性、舒适性和安全性。
