Experimental device for friction loss between contact wire and pantograph of high-strength high-speed rail

Abstract

The invention discloses an experimental device for friction loss between a contact wire of a high-strength high-speed rail and a pantograph. On the wire conducting assembly opposite to the pantograph assembly, the base is provided with a lateral swinging assembly that acts synchronously with the conducting wire assembly and simulates left and right swinging when the high-speed rail travels. , Simulate the bumpy vibration components that high-speed rail encounters bumps and vibrations, and use the wire conduction components to achieve high-speed transmission of experimental wires in a closed loop. Within a limited operating range, quickly and efficiently form the required friction loss experimental research samples, using lateral swing components. And the bumpy vibration component simulates the swing and bumpy vibration of the high-speed rail car during driving, improves the wear degree of the pantograph component and the experimental wire, and facilitates the friction loss experiment between the high-strength high-speed rail contact wire and the pantograph.

technical field [0001] The invention relates to the field of experimental devices, in particular to an experimental device for friction loss between a high-strength high-speed rail contact wire and a pantograph. Background technique [0002] The pantograph is an electrical device for electric traction locomotives to obtain electrical energy from the catenary. It is installed on the roof of the electric traction locomotive. As a high-speed train, the high-speed rail is driven by electricity. Mechanical energy is an efficient and reliable power source for high-speed railways. Therefore, the carriages of high-speed railways are also equipped with pantograph components. The pantograph components generally use telescopic brackets to support the sliding plate at the upper end to contact the electrical contact line. The pantograph components are especially It is often inevitable to wear the skateboard as a contact part, especially when it is installed on a high-speed rail car with ...

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
