Abstract:


Background: Broken belt arrest has become a hot topic in the fields of conveyor belt protection technology in the recent years. Recent studies and patents have found that there are few researches on hydraulic buffer system applied to belt arrestor for downward belt conveyor (HBSBADBC).

Objective: The purpose of this study is to research the dynamic properties of HBSBADBC and discuss the effect of the system parameters on buffer properties of HBSBADBC.

Methods: In this study, a hydraulic buffer system is applied to the belt arrestor. The operating principle and the mathematic model of HBSBADBC is presented and built, respectively. Furthermore, the simulation model of HBSBADBC is constructed based on MATLAB/Simulink. Finally, a simulation example with five different cases is provided.

Results: The experiment results show that the buffer properties of hydraulic buffer system can be changed or even improved with the change of system parameters such as piston diameter, piston rod diameter, relief valve spool diameter, spring stiffness and spring pre compression.

Conclusion: In the buffer stroke rang, designing smaller piston diameter, larger piston rod diameter, larger relief valve spool diameter, softer spring and greater spring pre compression conduce to more preferable buffer performance for HBSBADBC.
