The invention belongs to the technical field of emergency protection, and discloses a load protection system of a tubular pile mold hoisting operation trolley. A load monitor module, a control module, a load triggering module and the like are arranged, the load monitor module is arranged at the fixed end of a crane steel wire rope and used for detecting the load capacity of the crane steel wire rope; and the control module is connected to a control system of the travelling crane and is used for controlling the on-off of a cart and a trolley of the travelling crane in a load state, so that the load condition of the travelling crane can be effectively detected, the travelling crane is protected, and the service life of the travelling crane is prolonged. And the over-current protection module, the overheating and open-phase protection module and the over-speed protection module are connected with the control module, so that the motors of the cart and the trolley are protected, and the driving system is effectively protected.

    本发明属于紧急保护技术领域,公开了一种管桩模具吊运行车的负载保护系统,本发明中通过设置负载监测器模块、控制模块、负载触发模块等,其中,负载监测器模块设置在行车钢丝绳的固定端用于检测行车钢丝绳的载重力,并将测得的载重力信息传输至控制模块,控制模块接入行车的控制系统用于在负载状态下控制行车的大车和小车的断停,可以有效的进行检测行车的负载情况,对行车进行保护,并通过过流保护模块和过热、断相保护模块及超速保护模块与控制模块连接,用于对大车和小车的电机进行保护,有效的对行车系统进行保护。
