The invention discloses a control method of an electric hydraulic jack, which is characterized in that when the jack is controlled to rise, a rising button on control terminal equipment is directly pressed, a signal is sent to a main control module, a motor is controlled to start, the motor drives an electric pump to start, and hydraulic oil is pumped into the jack to drive the jack to jack; when the jack is controlled to descend, a descending button on the control terminal equipment is pressed, a signal is sent to the main control module, the electromagnet I is controlled to be powered on, and after being powered on, the electromagnet I drives a transmission part used for pushing an oil drain valve to act to open the oil drain valve for oil return, so that the jack descends; and the second electromagnet is connected with a metal piece in a magnetic attraction mode after being powered on, so that the transmission piece and the first electromagnet are kept at the position where the oil drain valve is pushed to be opened, and the main control module controls the first electromagnet to be powered off. The device is used for controlling the operation of the whole jack, and is also used for guaranteeing the normal operation of the jack, reducing faults, prolonging the service life and improving the safety during use.

    本发明公开了一种电动液压千斤顶的控制方法,其特征是控制千斤顶上升时,直接通过按动控制终端设备上的上升按钮,发送信号至主控模块,控制马达启动,马达带动电动泵启动,将液压油打入千斤顶驱使其进行顶升;控制千斤顶下降时,通过按动控制终端设备上的下降按钮,发送信号至主控模块,控制对电磁铁一供电,电磁铁一通电后驱动用于推动放油阀动作的传动件打开放油阀进行回油,使千斤顶进行下降;然后电磁铁二通电,电磁铁二通电后与一金属件磁吸连接,使传动件和电磁铁一保持推动放油阀打开的位置,且主控模块控制电磁铁一断电。该发明用于控制整台千斤顶的运行,同时用于保障千斤顶的正常运行,减少故障,提高使用寿命和使用时的安全性。
