Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and 2, the railway test platform for detecting scratches in the present embodiment includes a trailer platform 1, a rail 2, a winch mechanism 3, and a scratch testing mechanism 4.
Wherein the rail 2 is provided with a start point and an end point, in this embodiment the start point of the rail 2 is located on the right side of fig. 1 and 2, and the end point of the rail 2 is located on the left side of fig. 1 and 2. The experimental platform for detecting railway scratches of this embodiment requires the trailer platform 1 to be disposed at the starting point of the rail 2 and the track buffer block 22 to be disposed at the end point of the rail 2 when the platform is not in operation. The winch mechanism 3 is arranged at the terminal position of the rail 2 and is connected with the trailer platform 1 through a traction steel cable, and the winch mechanism 3 is firmly fixed with the ground at the terminal position. The scratch testing mechanism 4 is arranged at a specific position of the rail 2, specifically, the scratch testing mechanism is arranged at the middle section of the rail 2 and at the inner side of double tracks of the rail 2; if the device is combined with other peripheral detection devices, the device is arranged in the range of 5-30m from the starting point of the rail 2 and is positioned on the inner side of the rail double rail.
As shown in fig. 3, the trailer platform 1 is mounted on rails 2. The trailer platform 1 comprises two testing wheel pairs 11 and a bogie 12, wherein the testing wheel pairs 11 are arranged at corresponding positions of the bogie 12.
