[0002] The integrated inspection and maintenance equipment based on metro network tracks is a core piece of equipment in the field of urban rail transit operation and maintenance. It is mainly used for geometric parameter detection, fault inspection and emergency repair of key facilities such as metro tracks, catenary, and return rails. It is crucial for ensuring metro operation safety and improving operation and maintenance efficiency. Its performance is directly related to the operation and maintenance quality and operating cost control of metro network tracks. It is widely used in the daily maintenance and fault handling scenarios of metro operating units.
[0003] Currently, the operation and maintenance of subway tracks in the industry mainly relies on independent inspection vehicles and work vehicles, most of which are internal combustion or non-powered models. This type of operation and maintenance model has obvious drawbacks: First, the vehicle configuration cost is high. The user unit needs to purchase inspection vehicles and work vehicles separately, and also needs to equip at least two powered railcars for traction, rescue and escort. The vehicle purchase and long-term maintenance costs are high. Second, the equipment utilization rate is low. The inspection vehicle is only responsible for detecting track parameters, and the work vehicle only undertakes inspection and maintenance tasks. The functions are single and it is difficult to achieve resource sharing.
[0004] Therefore, it is necessary to provide a comprehensive inspection and testing device based on subway track network to solve the above-mentioned technical problems. Summary of the Invention
