Separated stepless speed regulation anchor cable tensioning equipment
The separation type stepless speed regulation anchor cable tensioning equipment comprises a hydraulic module and an electric control module which are arranged in a separated mode, the hydraulic module comprises an oil pump used for supplying hydraulic oil to a jack and a variable frequency motor used for adjusting the liquid supply speed of the oil pump, and the electric control module comprises a control mainboard and a frequency converter. The frequency converter is electrically connected with the control mainboard and the variable-frequency motor. According to the anchor cable tensioning device, the hydraulic module and the electric control module are separated from each other, so that safety accidents caused by faults of the hydraulic module or the electric control module under the ultrahigh pressure working condition are avoided, and therefore the safety during anchor cable tensioning is improved; in addition, the frequency converter can adjust the frequency of the current supplied into the variable frequency motor to conduct stepless speed regulation on the variable frequency motor, so that the liquid supply speed of the oil pump is adjusted in a stepless mode, and then stepless adjustment of the pressure of the liquid supply end of the jack is facilitated.
本发明公开了一种分离式无级调速锚索张拉设备，包括分离设置的液压模块和电气控制模块，液压模块包括用于向千斤顶供入液压油的油泵和用于调节油泵供液速度的变频电机，电气控制模块包括控制主板和变频器，变频器电连接控制主板和变频电机。本发明中，液压模块和电气控制模块相互分离，以避免在超高压工况下因液压模块或者电气控制模块发生故障而产生安全事故，从而提高锚索张拉时的安全性；另外，变频器可调节供入变频电机的电流频率，以对变频电机进行无级调速，从而无级调节油泵的供液速度，进而有利于无级调节千斤顶供液端的压力。
