Description

Technical Field

[0001] The utility model belongs to the technical field of railway tools, and in particular relates to a railway turnout wheel flange groove ruler. Background Art

[0002] A turnout is a line connection device that allows locomotives and vehicles to transfer from one track to another. It is usually laid in large quantities at stations and marshaling yards. Turnouts mainly include turnouts, crossings, and a combination of turnouts and crossings. Common types of turnouts laid on railways include single-opening turnouts, single-type symmetrical turnouts, three-opening turnouts, crossing crossovers, and crossing turnouts. Each of the above types of turnouts has an important component, namely the frog and the guardrail part. The guardrail of the turnout is usually set on both sides of the frog. It is an important device to control the running direction of the wheel, prevent it from impacting in the harmful space of the frog or climbing onto the tip of the frog heart rail, and ensure driving safety; in a movable heart rail frog, guardrails are generally only set on the side strands to prevent the side wear of the heart rail, and a guardrail wheel flange groove is formed between the active edge of the guardrail and the active edge of the guardrail.

[0003] The railway department periodically inspects the width of the guardrail wheel flange groove during daily equipment inspections. The current inspection method is to use a small steel ruler to measure at the corresponding position and read the reading perpendicular to the line of sight of the small steel ruler. The reading has an objective reading error that varies from person to person. According to Article 3.9.4 of the "Rules for Repair of Conventional Railway Lines" (No. 34 of the General Railway Engineering Department

[2019] ), the allowable error of the wheel flange groove width of the straight section of the guardrail is +3--1mm, and the reading is required to be accurate to 1mm. When we use a small steel ruler to measure the wheel flange groove of the turnout guardrail, because the wheel flange groove of the turnout guardrail is used all year round, the boundary is unclear, and there is usually a line of sight error in the reading under different light. Therefore, there is an urgent need for a simple measuring ruler to objectively overcome the measurement data deviation problem caused by manual reading errors, so that the data in the daily inspection of the railway department is more accurate and true. In response to the above problems, the inventor proposes a railway turnout wheel flange groove ruler to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is that when the existing small steel ruler directly measures the wheel flange groove of the turnout guard rail, it is easy to cause measurement data deviation due to line of sight error.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a railway turnout wheel rim groove ruler, including a small steel ruler, one end of the small steel ruler is rectangular, and the other end is a semicircular arc structure, scales are arranged on both sides of the small steel ruler, and the end of the small steel ruler located at the rectangle is the initial 0 scale line, a movable sleeve is slidably connected to the small steel ruler, the movable sleeve is a C-shaped structure as a whole, a bolt is arranged on the top of the movable sleeve, one side of the movable sleeve is rotatably connected to a vertical ruler through a rotating shaft, and the vertical ruler and the movable sleeve are an L-shaped structure as a whole, and bosses for limiting are arranged at both ends of the small steel ruler.

[0006] Furthermore, the interior of the movable sleeve matches the shape of the small steel ruler, and the clearance between the inner side of the movable sleeve and the small steel ruler is 1mm-2mm.

[0007] Furthermore, an extension platform is provided below the movable sleeve on one side of the C-shaped structure opening, and the bottom of the extension platform is in the same plane as the bottom of the movable sleeve, and the upper end surface of the extension platform is against one side of the vertical ruler.

[0008] Furthermore, the movable sleeve is located at the opening of the C-shaped structure and is an inwardly inclined slope.

[0009] Furthermore, the bolt is located at the top of the small steel ruler, and a screw hole matching the shape of the bolt is provided at the top of the movable sleeve.

[0010] Furthermore, the vertical ruler is located on the side of the movable sleeve away from the small steel ruler rectangular structure, and the movable sleeve on this side is in the same plane as one side of the vertical ruler. The length of the vertical ruler is 1.6 cm, and the length is the distance from one side of the small steel ruler to the top of the vertical ruler.

[0011] Furthermore, the boss is located on one side of the movable sleeve at the opening of the C-shaped structure, and the boss is located at a horizontal position at the connection between the movable sleeve and the vertical scale.

[0012] The advantages of the utility model compared with the prior art are:

[0013] 1. The railway turnout wheel flange groove ruler is made by adding a movable sleeve to the small steel ruler and setting a vertical ruler on the movable sleeve, so that the movable sleeve and the vertical ruler are L-shaped. When measuring, the movable sleeve drives the vertical ruler to slide to the measuring point. The sight blocked by the vertical ruler is just the standard measurement sight. At this time, the small steel ruler scale corresponding to the part where the movable sleeve on the small steel ruler is flush with the vertical ruler is the reading of the measured width, which overcomes the reading error caused by the sight deviation during manual reading, making the reading more standard and accurate;

[0014] 2. The railway turnout wheel flange groove ruler sets an extension platform on the movable sleeve to limit the maximum folding angle of the vertical ruler on the movable sleeve to 90 degrees, which not only ensures that the vertical ruler and the movable sleeve are at right angles when in use, but also enables the vertical ruler to be folded and portable when not in use;

[0015] 3. This railway turnout wheel flange groove ruler is simple and portable, which objectively overcomes the problem of measurement data deviation caused by manual reading errors, making the data used by the railway department in daily inspections more accurate and true.
