Embodiment 1

[0052] see Figure 1 to Figure 20 , a multifunctional measuring ruler for foldable turnouts, comprising a main ruler 1, an auxiliary ruler 2 and a vernier cover 3; the vernier cover 3 is movably arranged on the main ruler 1; Increase the measuring range of main scale 1.

[0053] like Figure 2 ~ Figure 4 As shown, the main ruler 1 includes a reference end plate 4, a rotating end plate 5 and a first ruler body 6; one end of the first ruler body 6 is connected to the reference end plate 4 through a first fastening bolt pair 9, and the rotating end plate 5 The pin shaft 8 is rotationally connected with the reference end plate 4, and there are two rotating end plates 5, which are symmetrically arranged on both sides of the first ruler body 6; the upper surface of the first ruler body 6 is provided with a first engraved degree scale 7;

[0054] like Figure 5 ~ Figure 7As shown, the bottom surface of the rotating end plate 5 is equipped with a sleeve 10, which is fastened by th...

example 1

[0063] Example 1: Turnout gauge detection. Gauge refers to the shortest distance between the inner working sides of the rails on both sides of the same track. like Figure 15 As shown, when measuring, first place the measurement reference surface 26 of the reference end plate on the rail top of one side, make the inner measurement surface 13 of the bushing close to the gauge line position of the working side of the rail head of the side rail, and then slide the combined state The vernier sleeve 3, place the measurement datum surface 27 of the vernier sleeve on the top of the rail on the other side, and make the outer measurement surface 24 of the measurement block stick to the position of the gauge line on the working side of the rail head, and finally read the measurement data through the cursor . The standard gauge in my country is 1435mm. By setting the range of the main scale 1 to be greater than 1435mm, the gauge detection can be completed without assembling the auxilia...

example 2

[0064] Example 2: Turnout distance detection. The support distance refers to the distance from the working edge of the straight outer strand rail head to the curved outer strand rail head working edge perpendicular to the straight strand direction. It is one of the important geometric dimensions controlling the relative position of the straight and curved strand rails in the turnout. like Figure 16 As shown, when measuring, first place the bottom surface of the reference end plate 4 on the rail top of one side, make the inner measuring surface 13 of the sleeve close to the gauge line position of the working side of the rail head on this side, and then slide the cursor sleeve 3 to place it The bottom surface is placed on the top of the rail on the other side, and the inner measuring surface 23 of the measuring block is placed against the gauge line of the working side of the rail head, and finally the measurement data is read through the cursor.

Abstract

The invention provides a foldable multifunctional measuring scale for a turnout. The foldable multifunctional measuring scale comprises a main scale and a vernier sleeve, the vernier sleeve is movably arranged on the main ruler; the main ruler comprises a reference end plate, two rotating end plates and a first ruler body. One end of the first ruler body is connected with the reference end plate, the two rotating end plates are connected with the reference end plate, and the two rotating end plates are symmetrically arranged on the two sides of the first ruler body; a sleeve is arranged on the bottom surface of the rotating end plate; The connecting line of the inner side measuring surfaces of the sleeves on the two rotating end plates and the zero graduation of the first graduated scale are in the same vertical plane; a first graduated scale is arranged on the first ruler body; the vernier sleeve comprises a main vernier sleeve. Vernier scales are arranged on the upper surface of the main vernier sleeve, and a raised measuring block is arranged on the lower surface of the main vernier sleeve. The measuring scale is multipurpose and rich in function. Functions of a gauging ruler and an offset ruler are combined, track gauges, offset distances, checking intervals, back protection distances and other turnout laying geometric dimensions can be measured, field operation and measuring tool management are facilitated, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of railway track measuring tools, in particular to a multifunctional measuring ruler for foldable turnouts. Background technique [0002] A turnout is a piece of track equipment that enables rolling stock to enter or cross over from one line to another. During on-site installation, the laying accuracy of the plane geometric dimensions of the turnout directly determines the safety, smoothness and comfort of the train crossing, which is the focus and difficulty of track laying. The planar geometric dimensions that need to be controlled during the laying of turnouts mainly include: gauge, support distance, frame, inspection interval and back protection distance, etc. At present, in the industry, the track gauge, inspection interval and back protection distance of turnouts are measured by gauge rulers; the distance of turnouts is measured by moment rulers; there is no special measuring tool for the size measure...
