Description

Technical Field

[0001] The utility model relates to the technical field of rail state measurement, in particular to a rail state measurement frame arranged on a monorail. Background Art

[0002] The spacing between domestic railway rails is 1435mm, and rail fine-tuning is done by double-track fine-tuning trolleys. For gantry crane running tracks installed in freight ports and railway freight stations, the double-track span is generally more than 10m, generally within the range of 30m, and double-track fine-tuning equipment is not applicable. The original measurement can be made by using a vernier caliper to center the rails, but the operation is cumbersome and is greatly affected by human errors. Single-track fine-tuning lacks relevant standard frames and cannot meet existing fine-tuning needs. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model proposes that the measuring prism is inserted into the insertion tube, and the supporting foot is clamped on the surface of the vehicle rail. Since the thickness of the vehicle rail is not fixed, the telescopic rod is pulled to make the telescopic rod be drawn out from the extension rod, so that the teeth are no longer clamped in the extension rod, and the telescopic rod is rotated. The second gear rotates with the telescopic rod, and the second gear drives the first gear to rotate after the rotation. The first gear is located in the slot, and the first gear drives the rotating rod to rotate after the rotation. A supporting block is fixed on the surface of the rotating rod, and the center of the supporting block is not at the same place as the center of the rotating rod.
