Technical field
The present invention relates to technical field of engineering machinery, especially a kind of hybrid power engineering machinery composite move controlling method.
Background technique
The equipment action normally composite move operationally of engineering machinery, such as equipment elevating movement is often along with rotation motion.A kind of hybrid power engineering machinery, what equipment elevating movement adopted is hydraulic driving as shown in Figure 1, hydraulic system shown in Fig. 1, include oil hydraulic pump 11 and oil cylinder 13, between oil hydraulic pump 11 and oil cylinder 13, be communicated with main valve 12 by main oil pipe, the control end of main valve 12 connects lifting pilot valve 14; Lifting pilot valve 14 is provided with descending operation handle, during work, promote descending operation handle, the guide oil that the oil outlet through being elevated pilot valve 14 is discharged enters the hydraulic control port of main valve 12, the displacement of valve rod of control bound 12, makes the equipment of engineering machinery move up and down.And equipment rotation motion employing is that the motor controlled by the master controller turning round operating grip and hybrid power engineering machinery drives; During work, promote revolution operating grip, output displacement signal to master controller, master controller according to displacement signal determination rotating speed of target, and control motor start rotation, till reaching rotating speed of target.But this hybrid power engineering machinery composite move controlling method also exists: its control between the two can not be compatible, the hydraulic control process of equipment elevating movement does not consider the automatically controlled process of equipment rotation motion, and the size of motor load can not be reflected on pressure and causes the inharmonic problem of hybrid power engineering machinery composite move.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of controlling method coordinating hybrid power engineering machinery composite move, and this method can solve the inharmonic problem of hybrid power engineering machinery composite move.
In order to solve the problem, the technical solution adopted in the present invention is: this hybrid power engineering machinery composite move controlling method, adopts the motor driving equipment rotation motion and the hydraulic system driving equipment elevating movement;
