分析了带式输送机皮带断带机理以及断带抓捕器的抓捕原理，采用电液控制方法，设计了一种电液控制型断带抓捕器。

An electric and hydraulic control type broken belt catcher of belt conveyor has been designed by using electric and hydraulic control theory .

在进行了以上理论分析的基础上，设计制造了新型全带宽方向的断带抓捕器，建立了新型断带抓捕器的三维模型，并对其关键结构的受力进行了有限元分析。

After a new type of broken-belt catcher based on the theoretical analysis , a three-dimensional model of the broken-belt catcher was established , and the finite element stress analysis to the key structure of the model was completed .

仿真实验表明，所设计的电液控制型断带抓捕器实现了断带前防止误动作，断带后抓捕响应快，抓捕过程安全、可靠.为物理样机的研制提奠定了坚实基础。

The simulation results show that the electric and hydraulic broken belt catcher designed can prevent the malfunction before catching the belt , catch with fast response after the belt broken , and catch with safety and reliability , which can provide reliable basis for the development of physical prototype .

最后，设计了断带抓捕综合实验台，为新型断带抓捕器进行了各项性能实验，并对实验结果进行了分析。

Finally , a comprehensive test-bed for the broken-belt catcher was built , the performance test of the broken-belt catcher were carried out , and the experimental results were analyzed .
