The invention discloses a control method of an electric hydraulic jack with a safety protection function, which is characterized in that when the jack is controlled to ascend, an ascending button of a positioning button area is pressed, and a main control module controls the jack to perform jacking; the current and the temperature of the motor are monitored in the jacking process, when it is monitored that the current of the motor exceeds a preset current parameter during positioning, the main control module controls an ascending button and a descending button in the positioning button area to be locked, and at the moment, the ascending button and the descending button in the positioning button area both lose efficacy; when the jack is continuously controlled to jack, the motor is controlled to be started by pressing an ascending button of the safety button area, the motor drives the electric pump to be started, and hydraulic oil is pumped into the jack to enable the jack to continuously jack. Through the arrangement, a worker can conveniently operate the electric jack to lift a vehicle or other heavy objects, meanwhile, the operation process of the jack is monitored and safely protected, and therefore the using safety of the electric jack is improved, and potential safety hazards are reduced.
本发明公开了一种具有安全防护功能电动液压千斤顶的控制方法,其特征是控制千斤顶上升时,按动定位按钮区的上升按钮,主控模块控制千斤顶进行顶升;顶升过程中对马达电流和温度进行监测,当监测到马达电流超过预设的定位时的电流参数后,主控模块控制定位按钮区的上升按钮和下降按钮锁住,此时定位按钮区的上升按钮和下降按钮均失效;继续控制千斤顶顶升时,通过按动安全按钮区的上升按钮,控制马达启动,马达带动电动泵启动,将液压油打入千斤顶使其继续进行顶升。通过本发明的设置,用于方便工作人员方便操作电动千斤顶举升车辆或者其他重物的同时,对千斤顶运行过程到监控和安全防护作用,从而提高电动千斤顶使用时安全性,减少安全隐患。
