The utility model relates to a reliability test device for a hydraulic hose assembly and belongs to the technical field of hydraulic transmission and control. The reliability test device for the hydraulic hose assembly is characterized by comprising a power oil source, a main control valve group, a durability pressure cylinder, a pressureproof bursting pressure cylinder, an auxiliary valve group and a charging pump motor assembly, wherein the power oil source is communicated with the main control valve group and the auxiliary valve group to control the durability pressure cylinder and the pressureproof blasting pressure cylinder, and switching between a pressureproof and bursting test of the hydraulic hose assembly and a durability test of the hydraulic hose assembly is realized by virtue of linkage of a three-position electromagnetic directional valve in the main control valve group and a three-position electromagnetic directional valve in the auxiliary valve group. The reliability test device for the hydraulic hose assembly has the advantages that integration level is high, structure is compact, a pressure test, a bursting test, a leakage test and a durability test can be carried out at the same time and reliability test requirements of various hydraulic hose assemblies can be met.
