Description

Technical Field

[0001] The utility model belongs to the field of contact network parameter detection, and specifically relates to a contact network detection ladder car system. Background Art

[0002] With the rapid expansion of the global railway network, especially the rapid development of high-speed railway (HSR) systems, unprecedented high standards have been put forward for the safety, reliability and maintenance efficiency of railway lines. With its high speed, large capacity and high punctuality, HSR has become an important part of the modern transportation system, and the power supply line, as the lifeline of its operation, is crucial to ensure the stable and efficient operation of trains. The power supply line is mainly composed of the contact network, among which the contact wire is the key component for directly transmitting electric energy to the train, and its state directly affects the stability and safety of power transmission.

[0003] In the daily maintenance and renovation of high-speed rail power supply lines, the geometric parameters of the contact wire, such as height, pull-out value, slope, hard points, etc., are key indicators for measuring the performance of the power supply system. The accurate measurement and adjustment of these parameters play a decisive role in ensuring good contact between the train pantograph and the contact wire, reducing arcing, preventing bow-off accidents, and extending the life of the equipment. However, in the traditional work process, the parameter measurement of the contact wire is usually carried out separately after the ladder car construction (such as replacement and adjustment of the contact wire), which not only increases the operation links and prolongs the overall construction period, but also may delay the timely discovery and correction of problems due to the inability to immediately feedback the construction effect.

[0004] Existing technical solutions, such as hand-push or hand-held contact line foundation parameter measuring instruments, have improved the flexibility and portability of on-site measurements to a certain extent, but they still rely on manual operation and are disconnected from the actual ladder truck construction process. This separate operation mode is not only inefficient, but may also introduce measurement errors due to environmental changes (such as temperature, wind force) or human factors, affecting the accuracy and reliability of the data.

[0005] Based on this, the utility model proposes a contact network detection ladder car system. Utility Model Content

[0026] Beneficial effects of the utility model:

[0027] Improve work efficiency: Traditional contact network inspection methods often rely on intensive manual operations and long operation cycles, which not only consumes a lot of human resources, but may also cause project delays. In contrast, the use of advanced contact network inspection ladder system devices can perform inspection and maintenance tasks simultaneously in one operation, significantly shortening the overall work cycle. This integrated solution greatly reduces manpower input and time costs, allowing the team to complete the inspection and maintenance plan faster, thereby accelerating the project process and improving overall work efficiency.

[0028] Enhanced immediate response capability: In time-sensitive maintenance activities, the application of the contact line inspection ladder system significantly enhances the immediacy of maintenance. By collecting and analyzing the basic parameters of the contact line before and after maintenance in real time, the staff can immediately evaluate the maintenance effect and quickly identify and solve any residual problems. This instant data comparison mechanism ensures the immediate discovery and handling of problems, avoids potential operational interruptions caused by delayed feedback, and improves the efficiency and quality of maintenance operations.

[0029] Improve detection accuracy and reduce interference: Traditional detection methods may affect detection accuracy due to long detection distances, environmental factors and other factors. However, the contact network detection ladder system can perform detection tasks with higher accuracy due to its design close to the contact line, reducing interference from external environmental factors and ensuring data accuracy. This close-range, high-precision detection capability is particularly important for preventive maintenance, helping to identify subtle signs of faults in advance and avoiding the risk of minor problems turning into major faults due to not being discovered in time.

[0030] Innovative detection methods and reduced manpower loss: The contact network detection ladder car not only integrates a variety of advanced detection technologies, such as high-sensitivity sensors, high-definition video monitoring and automated data analysis, but also reduces reliance on manual labor through automated processes. These diversified detection methods can comprehensively and deeply evaluate the state of the contact network without affecting normal operations, while greatly reducing errors and losses caused by human factors. With the improvement of intelligence, the system can also self-optimize the detection process, further improving the intelligence level and work efficiency of detection, and providing strong technical support for the safe and stable operation of rail transit.
