Study On The Reliability Of Hydraulic System Of Anchor Rig

At present, the anchor rig is mainly used in highway, railway, water conservancyproject construction, coal mine roadway construction and slope anchorage engineering,also used in the city construction of deep foundation pit supporting, construction hole,hole blasting and tunnel pipe shed construction support. With the national economicconstruction, the anchor rig demand is more and more big, the requirement for hydraulicsystem is more and more high.In this paper, the anchor rig hydraulic system of independent research anddevelopment of an enterprise as the research object, analyzes the working principle of thehydraulic system, and to study the reliability of the hydraulic system.First of all, the basic circuit Roofbolter hydraulic drive system was studied, the entirehydraulic system according to various hydraulic branch system, introduces the basicstructure of hydraulic system, introduces the main circuit function realization principleand function of hydraulic system, and the key components of selection calculation.Secondly, based on the research of the hydraulic system, establish the reliabilityblock diagram of the hydraulic system diagram and the circuit, and set up a reliabilitymodel of the system, grasp the logic relationship of each component in the system, theaverage life of system reliability and system life by mathematical expressions intuitivelyexpress. Based on the hydraulic system reliability model is established, the use of Matlabsimulation experiments, the system reliability curve, to study the reliability of thehydraulic system, and on the job site field test are introduced in this paper.Finally, combining with the fault repair record company has found, weak links andthe design process and the debugging process, the formation of fault tree analysisdatabase and case database, establishing the hydraulic system fault tree, the fault treeanalysis method as the basic method, complete fault tree modeling of hydraulic system.To provide a certain reference value for the hydraulic system problems later Roofbolterused in the design, development, production, testing and field in the.
