Structural Design and Simulation of Self-moving Support Equipment for Rectangular Tunnels
Aiming at the problems of poor adaptability of self-moving temporary support equipment to complex roadway environment,bending deformation of hydraulic prop and small net laying area,a self-moving support equipment was designed with net laying device suitable for rectangular roadway,and its main composition structure,working principle and main technical parameters were introduced.The ANSYS software was used to simulate and analyze the single set of telescopic door brackets.The results showed that the structural strength and deformation were within the allowable range.The simulation comparison of the base with or without auxiliary support showed that the auxiliary support of the base could effectively reduce the deformation and equivalent stress of the pillar,thus ensuring the stability of the support and improving the safety of the support.
