High-speed rail side wall radian measurement equipment

Abstract

The invention provides a high-speed rail side wall radian measuring device, comprising a trolley, a lifting mechanism, a display, a scanner, a limit wheel, a floating platform and a swing mechanism, the lifting mechanism and the swing mechanism are both arranged on the trolley, and the swing One end of the mechanism is fixed on the vertical guide rail of the lifting mechanism, the lower end of the swing mechanism is connected to the trolley through two sliding hinge supports, the horizontal swing of the swing mechanism drives the lifting mechanism to swing horizontally, and the scanner is connected to the lifting mechanism The slider is lifted and lowered together with the slider, and the limit wheel is arranged at the front end of the floating platform. The invention can perform area scanning, and has high efficiency in measuring the side wall of the car body; the power supply system of the equipment is integrated at the bottom of the equipment, and does not need to be moved and worked by supporting wires, which improves the adaptability of the detection instrument, facilitates the handling of workers, and reduces physical labor.

Description

technical field [0001] The invention relates to the field of measuring equipment, in particular to a high-speed railway side wall radian measuring equipment. Background technique [0002] The side wall of the high-speed rail car body has a large structure size, and the outer contour is a curved surface. The traditional measurement and inspection mainly uses the mold manufactured according to the shape of the car body section in the ideal form as a standard sample. Match, then observe the gap between the standard inspection tool and the car body, and measure whether it is within the required range of the outer contour, fill in and record it, so as to facilitate the later shaping and adjustment. [0003] The disadvantages of existing detection methods are: [0004] 1. Due to the various structures of the outer contour surface of the side wall of the car body, the sections of different measurement parts under the same car body will be different, resulting in a large number of ...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the various structures of the outer contour surface of the side wall of the car body, the sections of different measurement parts under the same car body will be different, resulting in a large number of standard samples for testing

[0005] 2. Due to the large size of the car body, the structure of the standard sample is also enlarged, which brings difficulties to the detection operation of the worker master. The labor intensity of the detection workers is high, and the detection efficiency is not high.

[0006] 3. After the manual measurement is completed, the data is not recorded or manually recorded in a paper document, which is not conducive to data analysis and storage, and the manual measurement error is large
