Description

Technical Field

[0001] The present invention relates to the technical field of track gauge verification, and in particular to a track gauge data stability measurement auxiliary device and a use method thereof. Background Art

[0002] A track gauge is primarily used to measure the gauge between two tracks on a railway line. A track gauge (track gauge calibrator) consists of a crossbeam, a fixed measuring block attached to the crossbeam, and a movable measuring block capable of sliding along the crossbeam, thereby simulating two tracks. After adjusting the spacing between the fixed and movable measuring blocks to the standard track gauge, the gauge gauge measures the distance between them. The difference between the gauge gauge's measurement and the standard track gauge is the gauge gauge error, thereby verifying the gauge gauge.

[0003] Track cant refers to the process of raising the outer rail relative to the inner rail during track construction and maintenance to balance the centrifugal force generated by trains traveling on curves. Track cant is simulated by raising the end of the track gauge near the movable measuring block.

[0004] The superelevation of the track gauge calibrator also requires regular calibration. The traditional calibration method uses a dial indicator to measure the heights of the fixed and movable measuring blocks relative to a reference surface, calculates the difference, and then calculates the actual superelevation value. The difference between the actual superelevation value and the simulated superelevation value is the superelevation error. This calibration method requires the use of a dial indicator, which is cumbersome and inefficient. Summary of the Invention

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The purpose of the present invention is to provide a track detector data stability measurement auxiliary device and a method for using the same, so as to solve the problems existing in the above-mentioned related technologies, simplify the operation steps, and improve the verification efficiency.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figure 1 、 Figure 2 This embodiment provides a track detector data stability measurement auxiliary device 2, including a straightedge 21, an auxiliary block 22 and a coincidence level 23.

[0036] The straightedge 21 is designed to rest on the fixed measuring block 11 and the movable measuring block 12 of the track gauge calibrator 1. The upper and lower surfaces of the straightedge 21 are parallel to each other. The auxiliary block 22 has a positioning surface 221 and a measuring surface 222. The positioning surface 221 forms an angle α with the measuring surface 222. The positioning surface 221 is designed to rest against the upper surface of the straightedge 21. The coincidence level 23 is designed to rest on the measuring surface 222. The coincidence level 23 has a fine-tuning knob located near the end of the track gauge calibrator 1 where the fixed measuring block 11 is located.

[0037] The working principle of the track detector data stability measurement auxiliary device 2 in this embodiment is as follows:

[0038] This embodiment replaces the existing micrometer height measurement with angle measurement, allowing the angle measurement value to be read directly. After reading the angle, the angle between positioning surface 221 and measuring surface 222 is summed or subtracted from the read angle to obtain the actual angle corresponding to the superelevation. The sine value corresponding to the actual angle is multiplied by the distance between fixed measuring block 11 and movable measuring block 12 to obtain the actual superelevation value. The difference between the actual superelevation value and the simulated superelevation value is calculated, and this difference is the simulated superelevation error of the track gauge calibrator 1.

[0039] Compared with the prior art, this embodiment replaces the height measurement of the micrometer in the prior art with angle measurement, and the angle measurement value can be read directly, thereby simplifying the operation steps and improving the verification efficiency.

[0040] As a possible example, in this embodiment, a notch is provided on the upper portion of one end of the auxiliary block 22 close to the fixed measuring block 11. The notch can reduce weight, thereby reducing consumables and reducing costs.

[0041] As a possible example, in this embodiment, a plurality of bosses of the same height are provided on the lower surface of the auxiliary block 22, and the lower surfaces of the bosses are positioning surfaces 221. For example, there are four bosses, which are distributed in a rectangular shape.

[0042] This embodiment further provides a method for using the track detector data stability measurement auxiliary device, using the track detector data stability measurement auxiliary device 2, including the following steps:

[0043] Step 1: Adjust the superelevation (i.e., the height difference between the fixed measuring block 11 and the movable measuring block 12) of the track gauge checker 1 to the superelevation simulation value.

[0044] Step 2: Place the straightedge 21 on the fixed measuring block 11 and the movable measuring block 12 of the track gauge calibrator 1 .

[0045] Step 3: Place the positioning surface 221 of the auxiliary block 22 on the upper surface of the straightedge 21 so that the distance between the auxiliary block 22 and the fixed measuring block 11 is d.

[0046] Step 4: Place the coincidence level 23 on the measuring surface 222 and read the angle value displayed by the coincidence level 23 .

[0047] Step 5: Calculate the actual angle corresponding to the superelevation according to the included angle between the positioning surface 221 and the measuring surface 222 and the measuring angle of the coincident level 23 .

[0048] Step 6: Multiply the sine value corresponding to the actual angle by the distance between the fixed measuring block 11 and the movable measuring block 12 to obtain the superelevation actual value.

[0049] Step 7: Calculate the difference between the actual superelevation value and the superelevation simulation value. The difference is the superelevation simulation error of the track gauge detector 1.

[0050] Since this method uses the above-mentioned track detector data stability measurement auxiliary device 2, it also has the above-mentioned advantages of the track detector data stability measurement auxiliary device 2, which will not be described in detail here.

[0051] As a possible example, in this embodiment, between step five and step six, the following steps are further included:

[0052] Turn the straightedge 21 180 degrees and place it back on the fixed measuring block 11 and movable measuring block 12 of the track gauge calibrator 1. Place the positioning surface 221 of the auxiliary block 22 against the upper surface of the straightedge 21, with the distance d between the auxiliary block 22 and the fixed measuring block 11. Place the coincidence level 23 on the measuring surface 222 and read the angle displayed by the coincidence level 23. Repeat this step several times, and calculate the average of the angles displayed by the coincidence level 23 as the measured angle of the coincidence level 23.

[0053] By taking multiple measurements and calculating the average value, the measurement accuracy is improved, thereby improving the accuracy of the verification results.

[0054] For example, the angle measured by the coincident level 23 is the average value of five measurements. According to different practical needs, those skilled in the art may also select other times of measurement.

[0055] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
