The invention discloses a control method of an automatic leveling terminal, and particularly relates to the technical field of forklifts, comprising the following specific steps: step 1, judging whether a pallet fork on a gantry is in a horizontal state or not: if so, entering step 5; if not, entering the step 2; step 2, judging whether a pallet fork on the portal frame inclines forwards or backwards; if the pallet fork is at the forward inclining position, entering step 3; if yes, entering the step 4; step 3 and step 4, respectively switching on a forward-tilting pump motor switch or a backward-tilting pump motor switch, and driving a valve port of an electric proportional electromagnetic valve to be closed according to a certain proportion by a leveling terminal; and fifthly, a valve port of the electromagnetic valve is closed, the oil way locking function is completed, and automatic leveling is completed. When the portal frame is at +/-1 degree, the inclined rotating speed of the pump motor is automatically reduced to 500r from 1000r, buffering is automatically realized when the portal frame is close to the horizontal position, the leveling action is effectively and accurately completed, and the controller can be driven through the leveling terminal, so that the situation that the portal frame shakes in the automatic leveling process is reduced.

    本发明公开了一种自动找平终端的控制方法,具体涉及叉车技术领域,包括具体控制方法的步骤如下:步骤一:判断门架上的货叉处于是否水平状态:是,进入步骤五;否,进入步骤二;步骤二:判断门架上的货叉前倾还是后倾:是前倾位置,进入步骤三;是后倾,进入步骤四;步骤三和步骤四:分别打开前倾或后倾泵电机开关,找平终端驱使电比例电磁阀阀口按照一定的比例闭合;步骤五:关闭电磁阀阀口,完成油路锁止功能,完成自动找平。本发明当门架在±1°时,泵电机的倾斜转速自动由1000r降低至500r,门架接近水平位置时自动实现缓冲,有效精准的完成找平动作,其可通过找平终端驱动控制器,因此降低了自动找平过程中的门架晃动的情况。
