Abstract

The invention discloses an integral dropper vibration spectrum acquisition device for a high-speed railway contact network. A non-contact measuring device for acquiring an integral dropper vibration spectrum belongs to the field of rail transit and mainly comprises an acquisition system and a control system, the acquisition system comprises a high-speed camera module (1), a telephoto lens (2) anda triangular support (3), and the control system comprises a PLC control unit (4), an industrial personal computer (5), a data transmission line (6) and a data display (7). According to the acquisition device, vibration images of contact lines (9) and carrier cables (10) at corresponding positions of six integral hanging strings (8) in a span when a train passes by are simultaneously measured neara railway through the high-speed camera module (1), so that the purpose of measuring the vibration spectrum of the integral hanging strings (8) in real time is achieved.

Description

technical field [0001] The invention belongs to the field of rail transportation and is suitable for measuring the vibration spectrum of the overall hanging string of a high-speed railway catenary. Background technique [0002] The overall hanging string is an important part of the high-speed railway catenary, one end of which is connected to the catenary catenary cable, and the other end is connected to the contact wire, which is used to increase the contact suspension point of the catenary, improve the sag and elastic uniformity of the catenary, adjust Contact the structural height of the suspension, and play a certain role in carrying and carrying current. [0003] When a high-speed train passes by, the pantograph slide plate on the top of the train and the contact wire carry out current-carrying frictional operation and take power from the contact wire to achieve the purpose of supplying power to the train. However, when the pantograph sliding plate is in dynamic contac...
