Problems solved by technology
[0003] In the process of railway maintenance, the bolts loosened due to insufficient pre-tightening force of the bolted connection, or the bolts failed due to excessive tightening torque, which caused accidents and affected the operation of the railway.
Among them, in March 2013, in Beijing-Tianjin Intercity, the bolts of the positioning line clamp were not fastened firmly and fell off, causing the positioner to invade below the contact line and scratch the pantograph of the passing EMU, which constituted a general class C railway traffic.

The invention provides a contact network maintenance quality monitoring system, which is characterized in that the pretightening force of bolts on a contact networkis set through a maintenance device, and the maintenance device transmits maintenance data to a server through a network. The server stores, analyzes and gathers the maintenance data, and displays the maintenance data through a monitoring platform. A mobile platform is connected with the server through a network and is used for checking the maintenance data. According to the monitoring system, the pre-tightening force if the bolts is set accurately at a maintenance end, pre-tightening force values, maintenance time, position information and the like are uploaded to a server end through a wireless network, the server end stores, classifies and summarizes data, and finally maintenance data are presented on the monitoring platform and the mobile platform; and therefore, maintenance quality monitoring becomes more convenient, the maintenance progress and the maintenance data can be clearly known, and the maintenance efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of railway maintenance, in particular to the maintenance of catenary, in particular to a quality monitoring system for catenary maintenance. Background technique [0002] Under the long-term, high-density, and high-speed operation of EMUs, the railway catenary has high requirements for dynamic stability, electrical stability, and mechanical stability. Especially for high-speed rail lines, the stability requirements have been raised to a higher level. High-speed rail management has the characteristics of high technical standards, many professional joint departments, and complex operating environment. These problems make high-speed rail power supply operation maintenance and safety technology management face enormous pressure and risks. It is an important subject of high-speed railway catenary research to control the "loosening and detachment" of catenary components, ensure firm installation, and ensure safe ...
