Description

Technical Field

[0001] The utility model belongs to the technical field of electrified railway maintenance, and in particular relates to a foldable high-precision contact network measurement bearing vehicle device. Background Art

[0002] The contact network is a high-voltage transmission line that is set up in a zigzag shape above the rails in an electrified railway and is used by the pantograph to draw current. The contact network is the main structure of the railway electrification project and is a special form of transmission line set up above the railway line to supply power to electric locomotives. It consists of contact suspension, support device, positioning device, pillars and foundation. The contact network needs to be inspected daily and the height of the contact network needs to be measured to ensure that it is in the best contact position when the vehicle passes.

[0003] The existing railway contact network maintenance measurement devices mainly include two methods: static laying measurement and push measurement. Affected by the standard track gauge of 1.435m, the existing contact network push measurement devices are large in size, with the maximum size after including the track wheels exceeding 1.5m. The equipment is large in size and inconvenient for one person to carry and operate, which has a great impact on the measurement efficiency under complex track conditions.

[0004] On the other hand, the contact network measurement error mainly comes from sensor errors and deviations of the parameters of the carrier vehicle relative to the track plane. The former is generally relatively fixed, while the parameters of the carrier vehicle relative to the track plane will inevitably undergo slight changes during the implementation process. The current method of measuring static parameters during the track-on process will bring certain errors, and the lack of dynamic monitoring devices during the implementation process is not conducive to improving the contact network measurement accuracy.
