A measuring ruler for variable section size of rail

Abstract

The invention discloses a rail variable section size measuring ruler, which comprises a reference seat, a main ruler, a main ruler vernier, an auxiliary ruler, an auxiliary ruler vernier and a positioning vernier; the top surface of the reference seat is used as a measurement reference surface; The seat is fixed; the main scale vernier and the positioning vernier that can slide up and down along the main scale are socketed on the main scale from top to bottom. The right side of the above-mentioned positioning vernier is provided with a positioning vernier measuring claw, and the right side is vertical as the first measuring surface; the right side of the main ruler vernier is connected to the left end of the auxiliary ruler; cursor. Below the vernier of the auxiliary ruler, there is a measuring claw of the vernier of the auxiliary ruler. The left side of the measuring claw of the vernier of the auxiliary ruler is vertical, and the lower end surface is horizontal, which serve as the second measuring surface and the third measuring surface respectively. The left end of above-mentioned main ruler vernier and datum seat can be respectively designed main ruler vernier measuring claw and datum seat measuring claw. The rail variable section size measuring ruler of the invention improves the measurement accuracy, integrates the measurement functions of various measuring tools, and makes the measurement convenient and efficient.

Description

technical field [0001] The invention relates to the technical field of railway tracks, in particular to a multifunctional vernier caliper for measuring variable cross-sectional dimensions in a turnout rail piece processing area. Background technique [0002] Steel rails such as point rails, long center rails, and short center rails in turnouts need to gradually process the width of the front end rail head from 0mm to the width of the original material. Several control sections are set in the variable section area in the middle, and the control section is controlled by measurement. The height of the rail and the width of the rail head are used to control the processing line type of the variable section area. [0003] The rail head width of the rail refers to the distance between the two points on the working side and the non-working side of the rail head at the gauge line position. Usually, the gauge line is 16mm below the top surface of the theoretical rail. Since the heigh...
