Design Of An Auxiliary Installation Equipment Of Four-bundle Spacer Damper

The erection of 500 k V high-voltage lines is mainly high-altitude erection,each phase of the 500 k V transmission line is composed of four strands of steel core aluminum stranded wires.In order to improve the ability of overhead lines to resist natural disasters,it is necessary to installfour-bundle spacer damper along the four-split transmission line reasonably.The current spacer rod installation method is manual installation.The installation workers carry spacers along the line,the working environment of workers is terribly bad and the work is highly dangerous.Due to the influence of workers’ own physical factors,it is difficult to carry all the spacers required for a single pitch at one time.Electric workers consume a lot of physical effort during online installation work,and the installation of spacers is inefficient.At present,studying an auxiliary installation equipment of four-bundle spacer damper has huge market demand and economic benefits.According to the structure characteristics of 500 k V transmission line and the construction and installation standard requirements of the four-bundle spacer damper,determined the working environment,functional requirements and technical parameters of the auxiliary installation equipment of four-bundle spacer damper.The article first discusses the research status of special working equipment for high-voltage lines at home and abroad,according to the needs of the equipment to complete the installation task of the spacer,designed the overall mechanical structure of the equipment,designed the overall mechanical structure of the equipment,explained in detail the mechanical structure and working principle of the walking device,spacer bar storage device,spacer bar installation device,safety protection device,spacer bar lifting fixture,and vertical lifting device,completed the overall mechanical structure design of the equipment,and use UG to carry out modeling and assembly of equipment entities.Secondly,according to the working environment of the spacer installation equipment,analyzed the force on the slope and the climbing ability of the equipment.Mechanical analysis and strength check of key parts of equipment complete the selection of stepping motors,reducers,screws,guide rails,linear actuator for the auxiliary installation equipment of four-bundle spacer damper.Then,the body control system and the upper computer control system of the auxiliary installation equipment of four-bundle spacer damper are designed,and the control flow chart is compiled.The touch screen is used as the upper computer control system,and the touch screen interface is written.The information transmission between the device body and the touch screen based on the Modbus communication protocol is introduced in detail,and the wireless communication between the device body and the touch screen is completed.Finally,according to the three-dimensional model drawn by ug,import Ansys Workbench software to simulate and optimize the mechanical structure to see if the mechanical structure meets the strength requirements.According to the force simulation results of ANSYS Workbench,the strength and stiffness of the mechanical structure are verified.
