The invention discloses a boarding ladder system, a control method and engineering machinery. The boarding ladder system comprises a base, a turnover ladder, a lifting oil cylinder, a locking device, a plurality of sensors, an electronic pump, an escalator control valve group and a controller, the base is fixed on the side of a vehicle body; one end of the turnover ladder is hinged with the base; the two ends of the lifting oil cylinder are hinged to the base and the overturning ladder respectively. The locking device is installed on the upper portion of the vehicle body and used for locking the overturning ladder. The plurality of sensors are mounted on the base and used for detecting the position information of the turnover ladder, and are mounted in the locking device and used for detecting the position information of the locking guide rod; the electronic pump is used for providing hydraulic power; and the escalator control valve group is used for realizing direction switching and closing of a hydraulic loop of the lifting oil cylinder and the locking oil cylinder. According to the boarding ladder system, a person can conveniently control descending and ascending of the turnover ladder through the controller, when the turnover ladder is located at the lowest descending position, the person can conveniently get on a vehicle, when the turnover ladder is located at the highest ascending position, the locking device locks the turnover ladder, and the safety of the boarding ladder system is improved.

    本发明公开了一种登车梯系统、控制方法及工程机械,包括底座、翻转梯、举升油缸、锁止装置、多个传感器、电子泵、扶梯控制阀组和控制器;底座固定在车辆车身侧面;翻转梯一端与底座铰接;举升油缸两端分别与底座和翻转梯铰接;锁止装置安装于车辆车身上部,用于锁定翻转梯;多个传感器安装于底座上用于检测翻转梯位置信息,安装于锁止装置内,用于检测锁止导杆的位置信息;电子泵用于提供液压动力;扶梯控制阀组用于实现举升油缸和锁止油缸液压回路的方向切换和关闭。本发明可以方便人员通过控制器控制翻转梯的下行和上行,当翻转梯处于下行最低位时,方便人员登车,当翻转梯处于上行最高位时,锁止装置锁定翻转梯,提高了登车梯系统的安全性。
