Problems solved by technology
The technical index of the milling operation unit is directly related to the precision of the rail milling and grinding of the rail. Unlike the assembly line products, the composition of the milling operation unit is complex, and each unit needs to be independently debugged before delivery.
[0006] Under normal circumstances, the milling operation unit needs to be hoisted on the car body. After the whole system of the whole car is connected and debugged, the line idle window is required. The status of each system of the whole car is ready, the personnel of each position of the whole car are in place, and all conditions are met at the same time. The commander-in-chief coordinates the line and vehicle system personnel to drive the rail milling and grinding car to the test line before debugging, and the test efficiency is very low
[0007] In my country, the railway lines are becoming increasingly busy, and the window time for the test line that can be provided for debugging of the milling unit is very small, and the debugging efficiency is also greatly reduced

The invention discloses a test platform for a milling operation unit of a steel rail milling-grinding vehicle. The test platform comprises a travelling crab, wherein an operation unit connecting plate is arranged on the travelling crab; the milling operation unit is arranged on the operation unit connecting plate; a supporting fixture is arranged on the operation unit connecting plate; and the operation unit connecting plate is fixedly mounted on the travelling crab through the supporting fixture. The test platform is perfect in function, is convenient to operate, is simple in structure, is safe and reliable, and can realize debugging and milling operation simulation of the milling operation unit of the steel rail milling-grinding vehicle and function / performance detection of the milling operation unit.
Description
technical field [0001] The invention relates to the field of railway maintenance equipment, in particular to a rail milling and milling unit test platform. Background technique [0002] With the rapid development of my country's railways, subways and other rail transit technologies, the increase in the axle load of locomotives and vehicles, and the increase in vehicle speed, higher requirements are placed on the quality of railway lines, and the treatment of rail surface diseases is imminent. [0003] The service life of railway and subway rails is controlled by fatigue cracks and wear caused by rolling contact. Fatigue cracks affect rail flaw detection, wheel and rail running status, increase maintenance costs, shorten the service life of rails, and even cause rail breakage; wear, especially the side wear of strands on the upper curve, causes the rail to go down the track prematurely. In order to delay the development of rail rolling contact fatigue damage and wear, and pr...
