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] Such as 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] Such as Figure 5 ~ Figure 7As shown, the bottom surface of the rotating end plate 5 is equipped with a sleeve 10, which is fastened...

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. Such as 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 auxi...

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. Such as 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 multifunctional measuring ruler for a foldable turnout, which includes a main ruler and a vernier sleeve; the vernier sleeve is movably arranged on the main ruler; the main ruler includes a reference end plate, a rotating end plate and a first ruler body; One end of the ruler body is connected to the reference end plate, and the rotating end plate is connected to the reference end plate. There are two rotating end plates, and the two rotating end plates are symmetrically arranged on both sides of the first ruler body; the bottom surface of the rotating end plate is equipped with a sleeve; The connecting line of the inner measuring surface of the bushing on the two rotating end plates and the zero scale of the first scale scale are in the same vertical plane; the first scale body is provided with a first scale scale; the vernier sleeve includes the main vernier sleeve; The upper surface of the main vernier sleeve is provided with a vernier scale, and the lower surface of the main vernier sleeve is provided with a raised measuring block. The invention has multiple functions and rich functions. Combining the functions of gauge ruler and support gauge, it can measure the geometric dimensions of turnouts such as gauge gauge, support distance, inspection interval, back protection distance, etc., which is convenient for on-site operation and measuring tool management, and is conducive to improving work efficiency.

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...
