Problems solved by technology

If the construction machinery is not kept in a horizontal state, it will not only affect the stability of the construction machinery during operation, but also easily cause accidents when the construction machinery is operating, especially when the construction machinery is operating on an uneven road surface. The probability and risk of accidents have increased significantly

Abstract

The invention discloses an engineering machine leveling control device, system and method and an engineering machine. The engineering machine comprises multiple supporting legs. Each supporting leg is driven by a corresponding supporting leg oil cylinder. Each supporting leg oil cylinder is correspondingly connected with a corresponding electromagnetic reversing valve in multiple electromagnetic reversing valves. The electromagnetic reversing valves are connected with a multi-way proportional valve. The control device comprises a first detection module used for detecting whether the supporting legs extend to the ground or not, a second detection module used for detecting inclination information in real time under the condition that the supporting legs extend to the ground, a processing module used for determining the supporting leg oil cylinders needing to be adjusted, the adjusting directions of the supporting leg oil cylinders and the control current of the multi-way proportional valve according to the inclination information, a first control module used for applying the control current to the multi-way proportional valve, and a second control module used for opening the electromagnetic reversing valves correspondingly connected with the supporting leg oil cylinders needing to be adjusted according to the adjusting directions so as to make the supporting leg oil cylinders needing to be adjusted move in the adjusting directions. Therefore, the engineering machine can be adjusted to the horizontal state.

Description

technical field [0001] The present invention relates to the field of construction machinery, in particular to a construction machinery leveling control device, system, method and construction machinery. Background technique [0002] Many construction machines need to spread out the outriggers to keep the construction machine in a horizontal state before carrying out work. After that, start working again. If the construction machinery is not kept in a horizontal state, it will not only affect the stability of the construction machinery during operation, but also easily cause accidents when the construction machinery is operating, especially when the construction machinery is operating on an uneven road surface. The possibility and risk of accidents are greatly increased. Contents of the invention [0003] The object of the present invention is to provide a construction machinery leveling control device, system, method and construction machinery, so as to adjust the constr...
