The invention relates to the technical field of equipment control, and provides a counterweight self-dismounting control system and method and a crane, the system comprises a controller, an alignment sensor, a bottom pin shaft driving cylinder, a bottom position sensor, a lifting oil cylinder, a top pin shaft driving cylinder and a top position sensor; the alignment sensor returns an alignment completion signal of the counterweight assembly and the rotary table to the controller; the controller sends a first lifting signal to the lifting oil cylinder after receiving the bottom pin shaft pull-out in-place signal, so that the lifting oil cylinder lifts a counterweight frame of the counterweight assembly to the position of the rotary table, the top pin shaft driving cylinder is controlled to be inserted into the top pin shaft, and the controller sends a second lifting signal to the lifting oil cylinder after the top pin shaft is inserted in place; the lifting oil cylinder lifts the balance weight base to the bottom of the balance weight frame, and the bottom pin shaft driving cylinder is controlled to be inserted into the bottom pin shaft. The process is completed by the controller in cooperation with all the components, manual repeated adjustment and confirmation are not needed, waste of manpower and time is reduced, and safety is improved.

    本发明涉及设备控制技术领域,提供一种配重自拆装控制系统、方法及起重机,该系统包括:控制器、对位传感器、底部销轴驱动缸、底部位置传感器、提升油缸、顶部销轴驱动缸和顶部位置传感器;对位传感器返回配重总成与转台的对位完成信号至控制器;控制器收到底部销轴拔出到位信号后发送第一提升信号至提升油缸,以使提升油缸将配重总成的配重架提升至转台位置,并控制顶部销轴驱动缸插入顶部销轴,在顶部销轴插入到位后控制器发送第二提升信号至提升油缸,以使提升油缸将配重底座提升至配重架底部,并控制底部销轴驱动缸插入底部销轴。上述过程均由控制器配合各部件完成,不需要人为反复调整和确认,减少了人力和时间的浪费,提高了安全性。
