Problems solved by technology

[0003] Aiming at the wear and tear problem of pantograph components, there are various online high-definition camera detection components, and there is also an effective method for detecting wear by using cross-sectional resistance and current methods disclosed in CN 108981556 B. However, these detection They are all based on pantographs that have been used for a long time. When researching the wear of contact wires and pantographs in the laboratory, it is necessary to collect the pantographs used for external installation, and to study the new structure and materials of pantographs. R&D poses significant constraints and requires an experimental setup that facilitates laboratory-based sampling studies of friction losses between the high-speed rail contact wire and the pantograph

Abstract

The invention discloses an experimental device for a frictional loss between a high-strength high-speed rail contact wire and a pantograph. The device comprises a base, an experimental bedplate for placing a pantograph assembly is arranged at the upper end of the base, and an experimental wire is mounted on a wire transmission assembly of which the rotation transmission direction is opposite to the pantograph assembly. A transverse swing assembly which synchronously acts along with the wire transmission assembly and simulates left-right swing of the high-speed rail during advancing is arranged in the base, a jolting and vibrating assembly which synchronously acts along with the wire transmission assembly and simulates jolting and vibrating of the high-speed rail is further arranged in the base, and high-speed transmission of experimental wires in a closed loop is achieved through the wire transmission assembly. Within a limited operation range, a required friction loss experiment research sample is quickly and efficiently formed, swinging and jolting vibration borne by a high-speed rail carriage in the running process are simulated through the transverse swinging assembly and the jolting vibration assembly, the abrasion degree of a pantograph assembly and an experiment wire is improved, and the friction loss experiment between the high-strength high-speed rail contact wire and the pantograph can be conveniently carried out.
