The invention relates to a safety protection method for crane overhaul. In the maintenance preparation stage, a maintenance command signal is sent to the maintenance safety protection controller through the maintenance remote controller, and the maintenance command signal is sent to the crane walking motor control loop by the safety protection controller; a maintainer disconnects the disconnecting switch, a disconnecting switch disconnection state signal is sent to the maintenance safety protection controller, and after the maintenance safety protection controller receives the disconnecting switch disconnection state signal, an electromagnetic lock locking instruction signal is sent to the disconnecting switch electromagnetic lock; after the maintenance remote controller sends a maintenance instruction for a period of time, the maintenance safety protection controller displays the received signal on the electronic indication board; and after the maintenance remote controller sends a maintenance release instruction for a period of time, the maintenance safety protection controller displays the received signal on the electronic indication board. The maintenance remote controller is always carried and operated by maintenance personnel in the maintenance process, so that the safety of the maintenance personnel is effectively ensured.

    本发明涉及一种起重机检修的安全防护方法。在检修准备阶段,通过检修遥控器发送检修指令信号给检修安全防护控制器,安全防护控制器向起重机行走电机控制回路发送检修指令信号;检修人员将隔离开关断开,隔离开关断开状态信号发送给检修安全防护控制器,检修安全防护控制器接收到隔离开关断开状态信号后,将电磁锁闭锁指令信号发送给隔离开关电磁锁;检修遥控器发出检修指令一段时间后,检修安全防护控制器根据收到的信号在电子指示牌上显示;检修遥控器发出检修解除指令一段时间后,检修安全防护控制器根据收到的信号在电子指示牌上显示。检修遥控器在检修过程中始终均由检修人员携带并操作,有效保证检修人员的安全。
