Description

Technical Field

[0001] The utility model relates to the technical field of track measurement, in particular to a track versine measurement tool. Background Art

[0002] When measuring the positron of a track curve, it is necessary to arrange measuring points on the track and then use a chord to measure. Currently known positron and direction measurement tools measure on a chord attached to 16 mm below the rail surface; however, for lines with anti-slip guardrails, crossings, vertical overlap sections, and rail side wear sections, due to space limitations, the chord cannot be effectively positioned 16 mm below the rail surface during measurement, resulting in the inability to correctly measure the positron value and direction value. Utility Model Content

[0003] In view of the defects of the prior art, the utility model provides a track positron measurement tool, which can realize the positron measurement of curved lines with anti-derailment guardrails, crossings, vertical and horizontal overlap sections and rail side wear sections.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A track positron measuring tool comprises a base and a ruler fixed on the side of the base, wherein the base is a rectangular parallelepiped structure and is used to be placed on the upper surface of the track, the ruler is closely fixed to the side of the base and is arranged perpendicular to the upper surface of the base, the lower end of the ruler extends out of the lower surface of the base for a distance and is used to be close to the working edge of the rail during measurement, and the ruler is provided with scales or a scale ruler along the height direction.

[0006] Furthermore, the ruler body is fixed to the side of the base by gluing.

[0007] Furthermore, the base is a rectangular parallelepiped magnet, and protective iron plates are respectively provided on the upper and lower surfaces of the magnet.

[0008] Furthermore, the ruler body is fixed to the side of the base by magnetic attraction.

[0009] Furthermore, the distance between the lower end of the ruler and the lower surface of the base is 16 mm.

[0010] Beneficial effect: The measuring tool provided by the utility model, through the introduction of a ruler, leads the original measuring point to the upper ruler position, so that data reading can be realized and maintained accurately, and effectively realizes the feasibility and convenience of the positive vector measurement of the vertical slow overlap section line, the anti-derailment guardrail section line, the crossing section line, and the rail side wear section line.

[0014] The following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0015] As Figure 1-2 shown, a track alignment measurement tool includes a base 1 and a scale 2 fixed to the side of the base 1. The base 1 is in a cuboid structure and is used to be placed on the upper surface of the track. The scale 2 is closely fixed to the side of the base 1 and is arranged perpendicular to the upper surface of the base 1. A section of the scale 2 extends below the lower surface of the base 1 for leaning against the working edge of the rail during measurement. The scale 2 is provided with graduations along the height direction or a scale ruler 3 is attached thereto.

[0016] The scale 2 is fixed to the side of the base 1 by an adhesive method; or a magnet 4 is arranged inside the base 1, and the scale 2 is fixed to the side of the base 1 by a magnetic attraction method.

[0017] When a magnet 4 is arranged inside the base 1, preferably, the magnet 4 is in a cuboid structure, and protective iron plates 5 are arranged on the upper and lower surfaces of the magnet 4.

[0018] Furthermore, the lower end of the scale 2 extends 16 mm below the lower surface of the base 1. Fixing the scale 2 to the side of the base 1 to form a measuring tool can lead the original measuring point upward to the position of the scale 2 above the track, facilitating data reading and measurement.

[0019] When using the measuring tool to measure the track alignment, three measuring tools form a group. Each measuring tool is respectively placed on the rail surface of the measuring point, and the scale 2 is leaned against the working edge of the rail. A string is stretched at the same height position on the scales 2 of the measuring tools at both ends. At the measuring tool in the middle, the string is at a certain horizontal distance from the scale 2. Since the measuring position 16 mm below the rail surface is translated to the scale plane above the rail surface through the scale 2, the problem that the steel tape cannot extend downward for measurement due to insufficient space at the measuring position is solved. At this time, the alignment value or direction value can be read by measuring the distance from the string to the scale 2 with a steel tape.

[0020] The measuring tool can be applied to the alignment and direction measurement in the following occasions:

[0021] 1: Alignment and direction measurement of the line in the section where anti-derailment guard rails are set. Since the height of the anti-derailment guard rail is higher than the measuring point of the working edge of the rail, the measuring point cannot be located and measured by the conventional method. With this tool, the measuring point is moved to the scale, realizing data measurement in this case.

[0022] 2: Direction measurement of the track in the crossing section. Since the width of the flange groove in the crossing is relatively narrow and the upper surface height of the crossing board is flush with the top surface of the rail, the measuring points cannot be located by conventional methods to complete the measurement. By using this tool, the measuring points are moved to the scale to achieve data measurement in this case.

[0023] 3: Chord and direction measurement of the track in the vertical and easement coincidence section. Due to the influence of the vertical curve, the chord and direction measuring points are not on the same horizontal plane, and the measuring points cannot be located by conventional methods to complete the measurement. By using this tool, the measuring points are moved to the scale to achieve data measurement in this case.

[0024] 4: Chord and direction measurement of the track in the section with side wear of the rail. After side wear occurs, the measuring points cannot be accurately located by conventional methods, resulting in deviation of the measuring points and inability to locate the measuring points to complete the measurement. By using this tool, the measuring points are moved to the scale to achieve data measurement in this case.

[0025] The utility model effectively realizes the feasibility and convenience of chord measurement for the track in the vertical and easement coincidence section, the track with anti-derailment guard rails, the track in the crossing section, and the track in the section with side wear of the rail. By introducing the scale, the original measuring points are led out to the scale position, enabling accurate data reading and maintaining accuracy.
