The horizontal module 1 is assembled with the height module 2 and the distance module 3 as the core module. The horizontal module 1 is placed horizontally on the rail. The height module 2 is used to measure the height of the coupler by cooperating with the horizontal module 1. The distance module 3 is used to detect the height of the lowest surface of the over-phase sensor from the rail surface, the horizontal distance of the center point of the over-phase sensor from the center line of the rail, and the inner distance of the wheelset by cooperating with the horizontal module 1.

The use scenarios are mainly concentrated in the manufacturing, maintenance and inspection processes of intercity EMUs. Since the intercity EMU needs to maintain extremely high accuracy and stability during operation, the dimensional measurement requirements of various vehicle components are very strict. The composite measuring ruler can meet the needs of accurate measurement of different parts of the EMU vehicle to ensure the safety and reliability of the vehicle.

[0035] In one embodiment, the horizontal module 1 includes a horizontal rod body 11 and a magnetic attraction member, the magnetic attraction member is located below the horizontal rod body 11, and the magnetic attraction member is magnetically matched with the rail. The horizontal rod body 11 is a hollow rectangular rod. The horizontal rod body 11 is placed on the rail, and the magnetic attraction member includes a balancing magnet 121 and a vertical magnet 122. The balancing magnet 121 is magnetically matched with the surface of the rail and can reliably maintain a horizontal state when assembling different measurement modules.

Preferably, the height gauge 22 is provided with a scale, and the slider body is provided with a fastening screw for fixing with the height gauge 22.

[0037] The design of the composite measuring ruler integrates multiple measurement functions, including length, width, height, etc. In terms of usage, the operator only needs to select the appropriate measurement module or function according to the specific measurement needs, and measure according to the operating steps of conventional measuring tools.

[0038] When measuring the height between the center line of the coupler and the rail surface, place the horizontal module 1 on the track in front of the coupler and keep it fixed, and vertically install the height module 2 with the support seat 21 downward within the range of the first indicator line 111 in the middle of the horizontal rod body 11, so that the second indicator line 211 of the support seat 21 is completely aligned with it, adjust the height of the measuring slider 23 and the extension position of the measuring head, align the measuring head with the measuring point of the coupler and fix it with a locking nut, and accurate data can be obtained by measuring the vernier of the measuring slider 23 and the scale of the height gauge 22.

[0039] In one embodiment, the distance module 3 includes a distance rod body 31, a connecting block 32, and a ruler claw 33. The distance rod body 31 is fixedly connected to the connecting block 32, and the connecting block 32 is slidably connected to the ruler claw 33. The connecting block 32 is provided with a height reading window 321 for reading the scale of the ruler claw 33. The two ends of the horizontal rod body 11 are provided with openings for inserting the distance rod body 31. The horizontal rod body 11 is rotatably connected to the distance rod body 31, and a distance reading window 112 for reading the scale of the distance rod body 31 is provided at the opening. The distance reading window 112 is provided with a secondary scale, which can be used to obtain an accurate horizontal distance value in combination with the scale on the distance rod body 31. The locking nuts provided on the two ends of the horizontal module 1 are used to fix the distance module 3 to avoid movement errors during the reading process after the measurement is completed. Preferably, the distance rod body 31 can rotate back and forth and slide inside and outside in the horizontal rod body 11. The connecting block 32 is provided with a locking screw for fixing with the ruler claw 33.

[0041] When it is necessary to measure the height of the lowest surface of the over-phase sensor from the rail surface and the horizontal distance between the midpoint of the over-phase sensor and the center line of the rail, place the horizontal module 1 on the rail between the over-phase sensors on both sides of the EMU body and keep it fixed, install the two distance scale modules into the two ends of the horizontal module respectively, and keep the scale claw 33 in a vertical state. When the limit pin falls into the limit slide groove 311, the rotation of the distance scale module will be limited while the telescopic sliding will not be hindered. At this time, the distance reading window 112 displays the horizontal distance scale. Adjust the telescopic distance module 3 and the height of the scale claw 33 so that the step of the scale claw 33 is close to the over-phase sensor in the horizontal and height directions. Tighten the locking nut at the distance reading window 112 and the locking nut at the sensor height reading window 321 to fix the distance module 3 as a whole. At this time, the horizontal distance of the sensor can be obtained through the distance reading window 112, and the sensor height can be obtained through the sensor height reading window 321.

The limit slots 311 are arranged along the length direction of the distance rod body 31. When the limit pin is located in the middle limit slot 311, the ruler claw 33 is in a vertical position, and the distance reading window 112 will display the scale of the horizontal distance between the center point of the phase sensor and the center line of the rail; when the limit pin is located in the limit slots 311 on both sides, the ruler claw 33 rotates ±30°, and the distance reading window 112 will display the scale of the inner distance of the wheelset.

[0043] When it is necessary to measure the inner distance of the wheelset, on the basis of measuring the phase-separated sensor morphology, the device is placed on the rail in front of the wheelset to be measured, the ruler claw 33 is adjusted to the same height of 22 inches, and the locking nut of the sensor height reading window 321 is tightened to fix it, and the two distance modules 3 are rotated 30° to the same side to make the limit pin fall into the other limit slide groove 311. At this time, the distance reading window 112 displays the scale of the inner distance of the wheelset, and the distance module 3 at one end of the device is telescopically adjusted to the reading of the distance reading window 112 is the initial scale "1400mm", and the locking nut at the distance reading window 112 is tightened, and the horizontal module 1 is moved to make the top of the step of the ruler claw 33 at this end close to the inner side of one wheelset, and the distance module 3 at the other end is telescopically adjusted so that the top of the step of the ruler claw 33 is close to the inner side of the other wheelset, and after tightening the locking nut at the distance reading window 112, the inner distance of the wheelset can be obtained from the distance reading window 112 at this end.

[0044] Preferably, the measurement results are recorded and data analysis is performed as needed. By comparing the measurement results with the design requirements or standard values ​​for processing and analysis, the dimensional accuracy and manufacturing quality of the EMU components can be evaluated.
