Abstract


As the elevator elevator guide rail guide system , affecting the elevator safety and comfort of the important parts. Most rail after cold working , straightness do not meet requirements , the need straightening machine straightening . With the rapid development of elevator guide rail industry and elevator guide rails enterprises continuously improve the accuracy requirements , the traditional manual alignment has been unable to meet the technological requirements of high-precision guide rail and mass processing needs . In this paper, an elevator guide rail manufacturer in accordance with the technical requirements , combined with the particularity Straightness assessment , develop a set of fixed rail via mobile hydraulic control console to achieve precise alignment guides automatically straightening system, rail is an innovative attempt to production areas . Firstly, in-depth study straightening theory , comparative analysis of several straightening stroke control mode , determine the appropriate alignment of the system control method . In elastoplastic theory, combined with T -rail section complex and asymmetrical features, derivation established with the top side of the rail load -deflection model and calculated according to the model T- rail straightening stroke empirical formula . Secondly, the design of the overall control system straightening structure and logic operation . Optional laser displacement sensors, multi-axis motion controllers, servo motors , stepper motors and industrial control computers and other building straightening control system hardware platform , combined with the actual operating system environment, the system motion controller, servo motor, step motor drives and other interfaces into the design . Finally , according to the straightening action logic and system requirements, propose a general framework of the application software . Using Visual C combined with multi -threading technology , database technology , Winsock networking technology, Windows regularly straightening technology developed control system software . According to the actual needs, design a friendly interactive environment , and the development of logging queries , the user information management, database emptied, parameter setting, rail curve inquiry function modules .
