TECHNICAL FIELD
[0001] The utility model relates to the technical field of rail surface standard line measurement and marking auxiliary equipment, in particular to a rail surface standard line measurement and marking auxiliary tool. BACKGROUND
[0002] Rail surface standard line is also called railway rail surface red line, which is a red horizontal limit line drawn on the inner side of catenary support or tunnel and station platform wall, used for recording the standard height and side clearance of the track surface at the place. This line is very important for ensuring the safe operation of electrified railway, because it involves the safety distance between catenary and train pantograph and the safe construction limit of railway operation.
[0003] Rail surface standard line measurement and marking is an important technical work, and the key steps and requirements are as follows:
[0004] 1. Measurement basis: The measurement work needs to be based on the coordinate control points and elevation control points along the line provided by the owner and design unit, as well as the line longitudinal section elevation diagram, slope table and super-elevation data provided by the station front and laying unit.
[0005] 2. Measurement method: In straight sections, the measurement personnel will determine the position of the "red line" mark according to the extension line of the rail surface connecting line on the support. In curve sections, the super-elevation of the outer rail needs to be considered, and the "red line" mark position is determined by the extension line of the rail horizontal line on the support with 1 / 2 of the design super-elevation value.
[0006] 3. Data recording: During the measurement process, the data of support side clearance, outer rail super-elevation and contact line height need to be recorded in time and counted.
[0007] 4. Safety requirements: Ensure traffic safety during measurement, and ensure the personal safety of construction personnel while ensuring normal operation of the railway.
[0008] 5. Precision control: During the measurement process, the accuracy of the measurement needs to be ensured, and the error should be controlled within ±20mm.
[0009] The traditional construction measurement of rail surface standard line has the disadvantages of inconvenient transportation and carrying of tools, poor operation quality, safety risk of personnel and machine intrusion into the limit, etc. It needs to be completed by multiple people within the window period, and the work quality and work efficiency are relatively backward. On this basis, we have researched a new type of rail surface standard line measurement and marking auxiliary tool, which aims to realize the non-intrusion into the traffic limit during the side clearance data measurement and rail surface red line positioning, and improve the portability of the measurement tool and the quality of the marking.
