Protection method for rotary motor of excavator
The protection method comprises the following steps that the included angle between a movable arm and a bucket rod is measured through a movable arm angle sensor and a bucket rod angle sensor, and actions are divided into no-load pressure building, no-load adjustment and on-load excavation in combination with the pressure of a main pump; when the included angle between the movable arm and the bucket rod is smaller than the minimum included angle and the main pump pressure is larger than the first pressure, it is judged that no-load pressure building action is conducted at the moment, rotation brake is started, and a rotation motor cannot rotate; when the included angle between the movable arm and the bucket rod is larger than the minimum included angle and the main pump pressure is smaller than the second pressure, it is judged that no-load adjustment is conducted at the moment, rotation brake is started, and the rotation motor cannot rotate; and when the included angle between the movable arm and the bucket rod is larger than the minimum included angle and the main pump pressure is larger than the second pressure, it is judged that the on-load excavation action is carried out at the moment, and rotation braking is relieved. When the excavator is located on a slope to carry out excavation work, loss of a brake pad of the rotary motor is reduced while sliding of the excavator is avoided, safety of excavation work is guaranteed, and cost is reduced.
本发明公开了一种挖掘机回转马达的保护方法，包括以下步骤：通过动臂角度传感器和斗杆角度传感器测得动臂与斗杆之间的夹角，结合主泵压力，将动作分为空载憋压，空载调整，带载挖掘；当动臂与斗杆的夹角小于最小夹角，主泵压力大于第一压力时，判断此时处于空载憋压动作，回转制动启动，回转马达无法回转；当动臂与斗杆的夹角大于最小夹角，主泵压力小于第二压力时，判断此时在空载调整动作，回转制动启动，回转马达无法回转；当动臂与斗杆的夹角大于最小夹角，主泵压力大于第二压力时，判断此时在带载挖掘动作，回转制动解除。能够在挖掘机处于斜坡进行挖掘工作时，避免溜车的同时降低回转马达制动片的损耗，保证了挖掘工作的安全性，降低成本。
