The invention belongs to the technical field of casting equipment, and particularly relates to a crane control system which is mainly characterized in that a simple anti-slip hook control module is added on the basis of an existing control system, and if the original double-closed-loop protection fails due to an electrical fault of a crane, the anti-slip hook control module is controlled by a time relay of the anti-slip hook control module, so that the anti-slip hook control module can be used for preventing the crane from slipping. And the control loop can be quickly electrified to start protection. Meanwhile, in the anti-slip hook protection, only the power supply of the brake loop is cut off, and the power supply of the lifting loop is not cut off, so that the situation that the output torque of the lifting motor is cut off too early to cause excessive impact on the brake system is avoided. By adopting the control system provided by the invention, the problem of hook slipping of the crane caused by electrical faults is effectively solved, major accidents are avoided, and safe production operation of the crane is ensured.

    本发明属于铸造装备技术领域,特别涉及一种起重机控制系统,主要在现有的控制系统的基础上,增加简单的防溜钩控制模块,若是起重机由于出现电气故障导致原有的“双闭环”保护失效后,在防溜钩控制模块的时间继电器的控制下,控制回路可快速得电启动保护。同时,在防溜钩保护中,只断开制动回路电源,不断开起升回路的电源,以免过早切断起升电机的输出力矩,对制动系统造成过渡的冲击。采用本申请提供的控制系统,有效地解决了起重机因电气故障造成的溜钩,避免发生重大事故,保证起重机安全生产作业。
