Description

Technical Field

[0001] This utility model relates to the field of railway transportation technology, specifically to a standard gauge railway gauge calibrator. Background Technology

[0002] In the railway transportation sector, ensuring the accurate measurement of various track parameters is crucial. The accurate measurement of parameters such as track gauge, superelevation, check interval, guardrail distance, and inclination error directly affects the safety and stability of train operation. The gauge gauge is displayed using an indicator device, and the superelevation value is reproduced using gauge blocks. As a vital tool for measuring these key parameters, the accuracy of the gauge gauge must be strictly guaranteed. Therefore, professional gauge calibrators are needed to periodically calibrate the gauge rod to determine whether the readings meet the standard requirements, thereby ensuring the reliability of railway track measurement data.

[0003] Some existing calibrators require manual lifting of the movable beam when adjusting it to measure different parameters. This method is not only labor-intensive, but also prone to causing the calibrator to shake due to human error during the lifting process, thus affecting the accuracy of the measurement results and failing to meet the requirements of high-precision measurement.

[0004] In addition, some existing calibrators have relatively simple functions. For the measurement of different parameters such as track gauge, superelevation, inspection interval, back guard distance and tilt angle error, it is often necessary to use a variety of different auxiliary devices or tools, and the measurement steps are relatively complicated. This not only increases the difficulty and workload of the measurement work, but also easily leads to errors in the process of multiple measurements and device replacements, reducing measurement efficiency and accuracy.

[0005] To address the above shortcomings, a standard gauge railway gauge calibrator was proposed. Utility Model Content

[0021] Please see Figure 1-4 The standard gauge railway gauge calibrator includes a fixed beam 12 and a movable beam 4, with the movable beam 4 positioned on top of the fixed beam 12.

[0022] The fixed beam 12 is made of seamless steel pipe. Fixed seats 15 are provided at both ends of the fixed beam 12. Three adjustable supports with a triangular structure are fixedly installed at the bottom of the two fixed seats 15 to adjust the level of the calibrator. A transverse level bubble 13 and a longitudinal level bubble 14 are provided on the outer surface of the fixed beam 12 to display the levelness of the calibrator.

[0023] A rotating shaft 19 is provided on the top of the fixed seat 15 on the right side. The movable beam 4 is movably installed on the top of the rotating shaft 19 and can rotate around the rotating shaft 19. An ultra-high value reproduction device 11 is provided on the top of the fixed seat 15 on the left side. Ultra-high value blocks can be placed on the top of the fixed seat 15 to simulate different ultra values. The movable beam 4 is raised for easy lifting.

[0024] An electric push rod 10 is also provided on the outside of the fixed base 15 on the left side. The top of the electric push rod 10 is connected to the bottom of the left end of the movable beam 4, which can save manpower, make the movable beam 4 more stable when lifting, reduce the shaking of the overall calibrator, and improve the measurement accuracy.

[0025] A gauge fixing measuring block 1 is fixedly installed on the top left side of the movable beam 4. A dovetail groove 20 is opened on the top right side of the movable beam 4. A gauge movable measuring block 6 is slidably installed on the top inner side of the dovetail groove 20. A gauge fixing hand screw 7 is provided on the side of the gauge movable measuring block 6, which is fixed to the dovetail groove 20. A first measuring plate 2 is fixedly installed on the inner end of the gauge fixing measuring block 1. A second measuring plate 5 is fixedly installed on the inner end of the gauge movable measuring block 6. The first measuring plate 2 and the second measuring plate 5 are on the same straight line. A gauge adjustment handwheel 9 is provided on the right side of the movable beam 4. The gauge adjustment handwheel 9 is movably installed with the gauge movable measuring block 6. A gauge display device 8, which is signal-connected to the gauge movable measuring block 6, is fixedly installed on the outer side of the gauge adjustment handwheel 9. Rotating the gauge adjustment handwheel 9 can change the gauge value, and the change is displayed by the gauge display device 8.

[0026] It should be noted that each measuring block, measuring plate, ultra-high value sub-block, and other components are made of high-quality stainless steel, which has been quenched and precision ground, making them rust-proof and durable.

[0027] The principle of track gauge measurement: Track gauge refers to the minimum distance between two rails within a 16mm range of the top surface of the rail. The standard track gauge is 1435mm. The calibrator uses two measuring blocks to simulate the standard track gauge: a fixed track gauge measuring block 1 and a movable track gauge measuring block 6. The movable track gauge measuring block 6 is installed in a dovetail groove 20 that can move left and right. The distance between the two measuring blocks is adjusted by gear transmission in the track gauge adjusting handwheel 9. The movable track gauge measuring block 6 is connected to a track gauge display device 8, which can be a digital display scale, to visually display the distance moved, thereby realizing the measurement of different track gauges.

[0028] The calibrator is equipped with a dedicated measuring rod 18, which can be placed on top of the measuring rod bracket 3 located above the movable beam 4. The actual length is measured by a length measuring machine and used to calibrate the gauge value of the calibrator.

[0029] Ultra-high measurement principle: Superelevation refers to the height difference between the outer rail and the inner rail on a curved track. When a train travels on a curved track, centrifugal force causes it to tend to tilt outwards from the curve. To balance this centrifugal force and ensure safe and stable train operation, the outer rail needs to be raised a certain height; this raised height is called superelevation. The standard track gauge is 1435mm, and the default rail head width is 70mm. Therefore, when calculating superelevation, the center-to-center distance between the top surfaces of the two rails is 1505mm.

[0030] The calibrator uses the sine principle to simulate the situation when two rails have superelevation. Different superelevation values ​​are reproduced by gauge blocks of different heights. The track gauge reading is compared with the superelevation reproduction value of the calibrator to detect whether the track gauge reading is out of tolerance.

[0031] Examine the measurement principles of the gap and backrest distance: The inspection interval is the distance from the working edge of the frog point rail to the working edge of the guard rail, which shall not be less than 1391 mm; the back rail distance is the distance from the working edge of the guard rail to the working edge of the wing rail, which shall not be greater than 1348 mm.

[0032] The calibrator uses the fixed gauge measuring block 1 to simulate the distance from the working edge of the frog point rail to the working edge of the guard rail, and the movable gauge measuring block 6 to simulate the distance from the working edge of the guard rail to the working edge of the wing rail. The gauge gauge is checked for deviation by comparing the difference between the reading of the gauge gauge and the standard value of the calibrator.

[0033] The principle of tilt angle error measurement: The top of the fixed gauge measuring block 1 is equipped with an inclination pad a16, and the top of the movable gauge measuring block 6 is equipped with an inclination pad b17. The two inclination pads with a 2° angle are used to directly measure the superelevation value of the gauge ruler when it is tilted.

[0034] How to use: First, install the three adjusting supports of the calibrator on the bottom of the fixed base 15 on the main body of the calibrator. Then, place the calibrator on the platform and rotate the adjusting screws of the adjusting supports to center the horizontal bubble 13 and the vertical bubble 14. Loosen the fastening screws on the first measuring plate 2 and the second measuring plate 5, remove the two measuring plates, and place the working measuring rod 18 on the measuring rod bracket 3. One end of the working measuring rod 18 should contact the working surface of the gauge fixed measuring block 1. Rotate the gauge adjusting handwheel 9 so that the working surface of the gauge movable measuring block 6 gently contacts the other end of the working measuring rod 18. Then, press the zeroing button on the gauge display device 8. Next, remove the working measuring rod 18 and install the two measuring plates. Note that the top surface of the measuring plate should be lower than the surface of the two measuring blocks. Remove the electric push rod control device, connect the electric push rod connector to the electric push rod 10, and finally connect the power supply. Before measurement, clean any foreign objects from the working surface of the calibrator and the working surface of the gauge ruler to ensure more accurate measurements.

[0035] Track gauge inspection: After adjusting the track gauge by rotating the track gauge adjustment handwheel 9 to the track gauge calibration point, tighten the track gauge fixing hand screw 7, place the track gauge on the calibrator, and the difference between the reading of the track gauge and the reading of the track gauge display device on the calibrator is the reading error of the track gauge at the calibration point.

[0036] Ultra-high zero-level [horizontal] detection: First, adjust the two bubble levels to the center, then place the gauge on the calibrator, and you can read the zero-point data of the gauge from the gauge.

[0037] Ultra-high reading detection: After raising the movable beam 4 of the calibrator to a suitable height using the electric push rod 10, place the ultra-high reproducible value block on the calibrator, then lower the movable beam 4 so that the ultra-high value measuring device 11 contacts the reproducible value block. Place the track gauge on the track gauge and read the ultra-high value from the track gauge. The difference between the ultra-high value and the ultra-high value reproducible value is the error of the track gauge at the detection point.

[0038] Check the interval and backrest distance: After adjusting the track gauge by rotating the track gauge adjustment handwheel 9 to the track gauge calibration point, tighten the track gauge fixing hand screw 7. Place the track gauge on the calibrator, pull the handle, and make one probe of the track gauge contact the first measuring plate 2 of the track gauge fixing measuring block 1. Read the reference interval reading of the track gauge. The difference between this reading and the standard reference interval value of the calibrator is the reference interval error at this calibration point. Keeping one probe of the track gauge in contact with the first measuring plate 2 of the track gauge fixing measuring block 1, pull the handle again, making the other probe contact the second measuring plate 5 of the track gauge movable measuring block 6. Read the back protection distance reading of the track gauge. The difference between this reading and the standard back protection distance value of the calibrator is the back protection distance error at this calibration point.

[0039] Tilt error detection: Place the tilting pads a16 and b17 on the top surface of the calibrator measuring block, and place the positioning plate on the bottom surface of the tilting pads into the measuring groove of the calibrator measuring block. Then place the track gauge on the tilting pads, and you can read the horizontal reading of the track gauge after it tilts 2° in the zero position.
