The invention discloses a semi-automatic tilting control system and method for a lifting appliance with the position capable of being memorized in a yard bridge. The system comprises a control system, a trolley walking mechanism, a right side lifting position encoder, a left side lifting position encoder, the lifting appliance, a first register and a second register. The control system collects position information of the trolley walking mechanism, the right side lifting position encoder is used for collecting the height from the lower portion of the right side of the lifting appliance to the ground, the left side lifting position encoder is used for collecting the height from the lower portion of the left side of the lifting appliance to the ground, and the height of the lifting appliance is further calculated. The control system stores the height and posture information of the lifting appliance when the trolley walking mechanism is located in a container truck channel in the first register, and stores the height and posture information of the lifting appliance when the trolley walking mechanism is located in a storage yard in the second register. When a manual operation signal is not received, the control system adjusts the posture of the lifting appliance according to the height and posture information of the lifting appliance in the first register or the second register. By means of the semi-automatic tilting control system and method, the box grabbing precision degree can be improved, and the safety coefficient can be increased.

    本发明公开了一种场桥可记忆位置的吊具半自动倾转控制系统及方法,系统包括:控制系统、小车行走机构、右侧起升位置编码器、左侧起升位置编码器、吊具、第一寄存器、第二寄存器。控制系统采集小车行走机构的位置信息,利用右侧起升位置编码器采集吊具右侧下方离地高度、利用左侧起升位置编码器采集吊具左侧下方离地高度,并进一步计算吊具的高度。控制系统将小车行走机构位于集卡道时的吊具高度及姿态信息存储于第一寄存器中,并将小车行走机构位于堆场时的吊具高度及姿态信息存储于第二寄存器中。在未收到手动操作信号时,控制系统根据第一寄存器或者第二寄存器的吊具高度及姿态信息来调节吊具的姿态。本发明能提高抓箱精准程度、增加安全系数。
