| Along with the development of drilling rigs, land rigs automatic drill is the developmenttrend .such as the transmission of the drill pipe, forming drill,and drill the emissions can all becompleted in the operating room, so not only simplifies data management and reducedowntime, and greatly improved the drilling rig at the time of the security.For the needs of automatic drill rigs, this paper design a set of a top drive system, ironroughnecks, wellhead mechanical equipment, drill pipe transmission, auto emissionsinstitutions and rooted for Automatic Drilling, drill from the high automation drilling rigintegrated control model to build a Integrated control of automated test platform rigs, for thebasis on carrying out integrated control of automatic drill rigs.The paper used the mechanical and electronic integration technology, computer 3Dmodeling and computer simulation techniques, on the land drilling rig mechanical structuredesign automation, fluid power control system design and component selection, power controlof each sub-system solution for digital simulation , study and solve the process of drillingoperations, coordination between the various control subsystems for the automated drillingtechnology ,using 3D modeling for the design of automated drilling rig, mechanical structuredesign with the drive system into consideration, combined with the actual drilling rig driverprogram, on the rational distribution of various functional modules and combined to completethe overall program of designing automation rig.According to the final determin ation of the structure program, I propose a reasonabledrive control scheme, a reasonable choice of hydraulic control device, and then complete thecontrol system design and control programming. Using simulation software to model andsimulate hydraulic control system and electrical control systems, according to the simulationresult, I adjusted control program and integrated control of building an experimental researchplatform. |
