| As the mainly tool used in the grid tension stringing, the performance of the steel wire rope affects the safety of construction directly, after a period of time, it need be maintained. Traction rope maintenance system through a thoroughly cleaning of the traction rope, effective detection and oiling maintenance, could prolong its life cycle, ensure the safety of construction. But during the process of using the system, the wire rope wheel appeared difficult clamping device and take-up device drove the spindle and the key part of connection problems compressive deformation. In order to solve the above problems, this paper researched the technology of clamping the rope round smoothly in take-up and feeding equipments of the traction wire rope maintenance system, also the dynamic simulation analysis was carried out on the take-up device at the same time, and optimized the key parts structural of the take-up device, the main research work was as follows:(1) Discussed the theory of peg-hole compliance assembly in depth; Direct at the problem that peg inserted into the hole of the rope wheel difficultly, studied the flexible clamping technology of wire rope pulley, analyzed the type of the rope wheel clamped positioning error, ensured the technical scheme was that to use the passive compliant assemble technology to compensate the error of the rope wheel clamping and positioning, to provide theoretical support for the design of the rope round soft clamping positioning error compensation equipments.(2) On the base of the rope round soft clamping technology study, ensured the design scheme of the rope wheel clamping and positioning in take-up and feeding equipments, through the necessary design calculation, to finish the design of the guide and position error compensation mechanism and the selection of the key parts of this equipment, and used the limit condition of the line rope wheel clamping device as the research object, made dynamic simulation analysis of the clamping rope wheel compliance by means of modeling with Solid Works and ADAMS, to verify the rationality and reliability of rope pulley clamping positioning error compensation device designation.(3) Investigating the characteristics of modeling methods of the flexible bodies such as the steel wire rope, completed the establishment of the take-up device geometry and simulation model of the steel wire rope by the methods of the ADAMS macro programming language, 3D design, add constraint, and so on, used the maximum working load of the take-up device as the research object, to analysis the dynamic simulation of the take-up process, to reveal the disciplinarian of the main shaft torque, and fork driving force changing with time, and got the mechanical parameters of the lifting mechanism screw, proposed the strategy of the contact force between the micro simulation steel wire rope and sheave, also got the contact force parameters between the steel wire rope and the rope pulley, as well as between the wire rope and the traversing mechanism rollers, the simulation results were analyzed in detail.(4) According to the dynamics simulation results, used the finite element to analysis the take-up mechanism by ANSYS Workbench, found the weak link of the force during the process of driving the mechanism, then carried on the structure optimization design, and then verified the reliability of the improved mechanism through the simulation software.This article was sponsored by a joint-school project “Environment-friendly Wire Rope Cleaning, Detecting and Maintaining Integrated Equipment”. |
