Background technique
Current urban rail transit in China development enters a high speed phase, and by year ends 2016, it is open-minded to share 30 citiesUrban track traffic operation, route reach 133, and total length has 48 up to more than 4,000 kilometers, while building city, building lineRoad total scale is more than 5,000 kilometers, has planned that total line length is more than 7,000 kilometers.It can be seen that the daily dimension of urban track trafficThe demands such as a large amount of line equipment inspection, tool materials transport are needed in shield.
With the accelerated development of urban track traffic, a large amount of maintenance personnel's sectional inspection is needed.But current inspection sideFormula inefficiency, means fall behind, and consume a large amount of human resources, therefore metro operation cost is high.
Currently, the inspection means that domestic city rail traffic mainly uses is engineering truck+manual inspection modes, i.e., to bigThe transport of part equipment uses engineering truck, and artificial walking inspection mode is taken in the inspection of everyday devices.But this mode exists such asLower defect:
1) waste of human resource is serious.
Each profession of metro operation unit requires the person of sending someone and periodically carries out line data-logging, checks to include line status, connectsThe plurality of devices working conditions such as net-fault situation, transponder state and wireless signal coverage strength.Gradually with urban track trafficDevelop to suburb, have already appeared more than ten kilometers long of big section, need more and more maintenance personnel's sectional inspections, is examined making an inspection tourCha Zhong consumes a large amount of human resources.
2) equipment manufacturing cost is higher and purposes is limited.
The mode of movement of mechanization at present mainly uses engineering truck to realize.It can only between each route of Urban Rail TransitRealize that vehicle cross-line uses by limited interconnection, but modes of devices and administrative provisions all difference between each route, acrossLine schedule job of changing trains or buses is complex.It is generally used the mode that each route all purchases engineering truck, engineering truck separate unit cost oneAs 5,000,000 or more, and be only able to satisfy general transportation demand, can not directly carry brakingization repair apparatus.
3) inspection means fall behind quality and can not ensure.
Manual inspection more depends on the professional skill and sense of responsibility of patrol officer, the judgment criteria that do not fix and examinesCore foundation.Some automation inspection technology (such as rail smart flaw detection, fastener inspection, the wireless field density intellectual analysis occurred at presentDeng), it all has higher requirements for the speed of service of inspection device, smoothness, track consistency.Artificial hand push can only be used nowThe mode of vehicle is realized, is increased personnel labor intensity and not can guarantee the high-precision requirement for realizing inspection device.
