Automatic online steel rail straightness measuring instrument

Abstract

The invention discloses an automatic online steel rail straightness measuring instrument. The automatic online steel rail straightness measuring instrument comprises a machine frame. A measuring ruler frame is arranged on the machine frame. A longitudinally-moving measurement trolley is arranged on the measuring ruler frame. A measuring mechanism used for measuring the steel rail straightness is arranged on the measuring trolley. A plurality of parallel slide rails which are transversely arranged are arranged on the machine frame. A transversely-moving beam arranged in the longitudinal direction is arranged on the slide rails and is connected with the slide rails in a sliding mode. A transversely-moving mechanism for making the transversely-moving beam transversely move on the slide rails is arranged on the machine frame. Automatic lifting mechanisms for making the measuring ruler frame do vertical movement are arranged at the two ends of the transversely-moving beam. The automatic online steel rail straightness measuring instrument has the advantages that the surface curves of the top face and the side face of a steel rail can be measured at the same time, accuracy is high, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of rail detection, in particular to an online rail straightness automatic measuring instrument. Background technique [0002] The inspection of the straightness of the rails in the production process, one of the quality indicators of the ex-factory products, is mainly manual inspection, which mainly checks the flatness of the treads at both ends of the rail at 0-1 meters, 0-2 meters, and 1-3 meters. and side straightness. By manually holding an aluminum-magnesium alloy ruler and feeler gauge with a length of 2 meters, measuring it on a stationary rail tread or side, and then measuring the gap between the ruler and the rail with different specifications of the feeler gauge to judge the straightness Whether the degree meets the standard requirements. Such an operation method has shortcomings such as inconvenient operation, unbalanced pressure, inaccurate measurement, inconvenient data recording, and error-pr...

AI Technical Summary

Problems solved by technology

[0004] 1) Inconvenient operation

The aluminum-magnesium alloy ruler is long (2 meters), and it is inconvenient to operate when it is pressed on the surface of the rail, especially the side. The measurement requires the cooperation of two people.

[0005] 2) The measurement process cannot reflect the entire measurement surface (2 meters), only the deepest point can be found

[0006] 3) The measurement must be performed in two steps, measuring the tread and measuring the side

[0007] 4) The measuring ruler is easily deformed

Due to the inconvenience of operation and placement, the measuring ruler is easily deformed

[0008] 5) There is no historical data and curves for review

[0009] 6) The pressure is unbalanced during the measurement, and the measured value is easy to be distorted
