Abstract: Aiming at the shortcomings of traditional mechanical and hydraulic full-face broken belt catcher, a new type hydraulic system of broken belt catcher is proposed. The combination and design of cartridge valve and the shuttle valve is used to make accumulator charged and draingaged, which realizes that the broken belt is captured. The working principle on the hydraulic system of broken belt catcher is introduced. The influence of the key parameters of the accumulator and the hydraulic cylinder on the system capturing performance is analyzed based on AMEsim, which provides a theoretical basis for the design and optimization of the hydraulic system.
