Introduction
Analysis of standard technical framework
| Technical dimensions | Requirements of this standard | Comparison with conventional standards |
|---|---|---|
| Operation efficiency | Rail changing ≥500m/h Sleeper changing ≥16 sleepers/min | Rail changing 300-400m/h Sleeper changing 8-12 sleepers/min |
| Environmental adaptability | Altitude 5100m Temperature -10℃~+50℃ | Altitude 2000m Temperature -5℃~+45℃ |
| Synchronous operation capability | 8 synchronous functions (including fastener recovery/ballast leveling) | 4-5 basic functions |
Core technology innovation
Compound operation system: Clause 4.1.19 of the standard innovatively proposed a synchronous replacement device for rails and sleepers, which is realized through integrated design:
- The automatic fastener recovery system (4.2.12.1) adopts magnetic conveyor belt technology with a drop rate of <0.5%
- The lateral adjustment accuracy of the sleeper centering mechanism (4.2.12.3) is ±5mm, which is better than the industry benchmark of ±10mm
- The hydraulic overload protection device (4.2.3) is set with three levels of pressure threshold
Implementation Guidelines
Response to special working conditions in plateaus
According to clause 4.1.23, when the altitude is ＞2000m, please note:
- Diesel engine power compensation coefficient ≥1.15
- Add plateau cooling device to the hydraulic system
- Insulation level of electrical components increased to Class F
Safety Control Red Line
Mandatory requirements of the standard (4.1.12):
- The fire protection system must comply with the UIC642 international standard
- A dual-circuit emergency stop device is installed in the running track area
- Engineering medical limit value of noise control 87dB(A)
Standard Evolution Analysis
Compared with the 2008 version, this standard has been mainly upgraded:
| Technical indicators | 2016 edition | 2008 edition | Improvement range |
|---|---|---|---|
| Maximum operating slope | 20‰ | 15‰ | +33% |
| Sleeper laying accuracy | ±10mm | ±15mm | Accuracy improved by 50% |
| Test items | 38 items | 25 items | 13 new key tests |
