METHOD OF CHECKING READINGS AT MEASURING PARAMETERS OF RAIL GAUGE USING MULTIPURPOSE GAUGE Russian patent published in 2006 - IPC E01B35/02 

FIELD: railway transport; track gauge measurements.

SUBSTANCE: proposed multipurpose gauge contains rod, fixed and movable stops, handle with tie-rod guide, device for determining railway track gauge with scale and device for determining distance between working faces of core and guard rail and distance between working faces of check rail and guard rail furnished with scales, respectively, carriage for checking ordinates of transition curves, width of troughs and side wear of rail head furnished with end piece with scale and mating with scale on tie-rod. Proposed method of checking comes to the following: check measurement of gauge is carried out by means of carriage whose end piece is fixed relative to CHECK position notch made on end piece. Then carriage is shifted to side of movable stop until end piece comes in contact with side working face of rail head and readings are taken from carriage scale relative to GAUGE CHECK position notch found on rod. Then gauge is measured by known method. Difference between readings obtained by known method and check measurement should not exceed gauge measurement error. Correspondence of readings is determine by comparing track gauge measurements and measurements of distance between core and guard rail or measurement of distance between check rail and guard rail. Difference between any values of gauge readings and distance between working faces of core and guard rail or distance between working faces of check rail and guard rail should be fixed.

EFFECT: improved maintenance of track gauge and quality of measurements.
