The invention relates to the technical field of safety monitoring systems, and discloses a safety monitoring and protecting system and method for a portal crane. The safety monitoring and protecting system for the portal crane comprises a crown block stroke measuring instrument, a cart stroke measuring instrument, a winch lifting measuring instrument, a levelness measuring instrument, a hook weight measuring instrument, a wind speed measuring instrument and an infrared sensor, wherein the crown block stroke measuring instrument, the cart stroke measuring instrument, the winch lifting measuring instrument, the levelness measuring instrument, the hook weight measuring instrument, the wind speed measuring instrument and the infrared sensor are all in electrical output connection with a data acquisition module. According to the safety monitoring and protecting system, before the portal crane is started, all modules of the portal crane are subjected to self-inspection, so that the state of the portal crane is obtained, the safety accident caused by starting under the condition that a fault exists is avoided, an alarm can be given out in time when data are abnormal, and the portal crane is controlled to be braked emergently, so that the safety of the portal crane during operation is improved.

    本发明涉及安全监控系统技术领域,且公开了一种门式起重机安全监控保护系统及方法;本门式起重机安全监控保护系统包括天车行程测量仪、大车行程测量仪、卷扬机升降测量仪、水平度测量仪、钩重测量仪、风速测量仪和红外线传感器,所述天车行程测量仪、大车行程测量仪、卷扬机升降测量仪、水平度测量仪、钩重测量仪、风速测量仪和红外线传感器均电性输出连接有数据采集模块,本发明在门式起重机启动前对其各个模块进行自检,从而获得门式起重机的状态,避免在其存在故障的情况下启动,从而造成安全事故,且在数据异常时能够及时发出警报以及控制门式起重机进行紧急制停,从而增加了门式起重机运行时的安全性。
