The invention provides a lifting height early warning and automatic correction method, which is used for a bridge crane, and is characterized by further comprising a limiter, a control system and an alarm, and the specific method is as follows: 1) presetting an early warning value and an alarm value on the control system; (2) the contact position of a limiting stopper is determined, the hoisting mechanism is operated, the position of the limiting stopper relative to the hoisting mechanism is adjusted, and when the hoisting mechanism is operated to the early warning value, the limiting stopper is triggered; and (3) the lifting mechanism is automatically operated, when the limiting stopper is triggered in the operation process of the lifting mechanism, the lifting mechanism transmits the height of the position where the lifting mechanism is located to the control system, if the height value of the position where the lifting mechanism is located is within the alarm value range, the alarm starts to give an alarm, and the lifting mechanism stops working. The control system automatically adjusts the position of the hoisting mechanism after receiving the signal; and if the height value of the position is outside the alarm value, the hoisting mechanism operates normally.
本发明提供一种起升高度预警及自动校正方法,用于桥式起重机,其特征在于,还包括,限位器、控制系统和报警器,具体方法如下:1)在控制系统上预设预警值和报警值;2)确定限位器的触点位置,运行起升机构,并调节限位器相对起升机构的位置,使得起升机构运行至预警值时,所述限位器被触发;3)自动运行起升机构,当所述起升机构运行过程中触发所述限位器时,所述起升机构将其所在位置的高度传递至所述控制系统,若所在位置的高度数值在报警值内,所述报警器开始报警,所述控制系统接收到信号后自动调节所述起升机构的位置;若所在位置的高度数值在报警值外,起升机构正常运行。
