Excavator rotation delay control system and control method
The invention discloses an excavator rotation delay control system and method, and belongs to the technical field of excavator control. Comprising a speed reducer and a motor which are mutually connected, an input shaft of the speed reducer is provided with a brake device, the brake device is connected with a brake oil cylinder and driven by the brake oil cylinder, the brake oil cylinder is connected with a control valve through a pipeline, an oil discharge port of the control valve is connected with a delay valve, and an outlet pipeline of the delay valve is connected with an oil tank. And the flow rate of the delay valve is matched with the volume in the brake oil cylinder so as to be matched with the required delay time. And when the excavator stops rotating, the control pipeline stops supplying oil to the SH oil port of the control valve, the control valve is reset, the hydraulic oil in the brake oil cylinder slowly flows out through the delay valve, and delay control is carried out. According to the rotary system of the excavator, the brake oil cylinder drives the brake device to effectively lock the speed reducer for braking, and the time delay control function can be achieved through the time delay valve.
本发明的一种挖掘机回转延时控制系统及控制方法，属于挖掘机控制技术领域。包括相互连接的减速机和电机，减速机输入轴设有刹车制动装置，该刹车制动装置连接有制动油缸并被制动油缸驱动，制动油缸通过管路连接控制阀门，控制阀门的卸油口连接有延时阀，延时阀的出口管路连接油箱，延时阀的流量速率与制动油缸内容积相配合以匹配所需延时时间。当挖掘机停止转动时，控制管路停止向控制阀门的SH油口供油，控制阀门复位，制动油缸内的液压油通过延时阀缓慢流出，进行延时控制。本实施例的挖掘机回转系统通过制动油缸驱动刹车制动装置对减速机进行有效锁紧进行刹车，且可以通过延时阀实现延时控制功能。
