Description

Technical Field

[0001] This utility model relates to the technical field of track gauge calibration equipment, specifically a multifunctional track gauge grating calibration device. Background Technology

[0002] Track gauges are commonly used instruments for measuring track spacing. To ensure the accuracy of the data they acquire, mandatory verification is required before use. Verification includes checking the length and superelevation parameters. For this purpose, as shown in a track gauge verification device with application number CN202210918449.0, the verification equipment needs to have lateral and vertical adjustment functions and use a grating for numerical reading to ensure accuracy. To further confirm the accuracy of the track gauge measurement data under length variations, repeated verification is generally performed. However, conventional equipment typically only has one type of standard frame, which cannot meet this requirement. Utility Model Content

[0003] To address the issue that a single calibration device typically only has one type of standard frame, this invention provides a multifunctional track gauge grating calibration device.

[0004] The technical solution of this utility model is as follows: A multifunctional track gauge grating calibration device includes an installation platform. A track gauge measuring mechanism and a superelevation measuring mechanism are arranged at intervals above the installation platform. The track gauge measuring mechanism is provided with a horizontal adjustment seat that can move in a horizontal plane, and the direction of movement of the horizontal adjustment seat is away from or towards the superelevation measuring mechanism. The superelevation measuring mechanism is provided with a vertical adjustment seat that can move in a vertical direction. Above the horizontal and vertical adjustment seats, there are corresponding center placement parts and side placement parts. The center placement part is used to set the standard frame, and the side placement part is used to set the track gauge. The standard frame includes a standard straight beam with a regular polygonal cross-section. An angle sensor is set at the center position on each side of the standard straight beam, and each side has symmetrically arranged plug-in parts at both ends that cooperate with the center placement part.

[0005] Based on actual needs, the existing standard frame is modified to have symmetrical plug-in structures at multiple length positions. Therefore, the gauge can be calibrated after the length is changed, and this can be achieved simply by rotating the standard frame, making the operation convenient and simple.

[0006] In order to change the length parameters for gauge calibration, the distance from the center position of the interlocking part on each side of the standard straight beam is different.

[0007] To avoid mutual interference, the two ends of the standard straight beam connector do not extend outward relative to the side surface.

[0008] To avoid obstruction of rotation, the standard straight beam is provided with a mounting groove, and the angle sensor is installed in the mounting groove with its upper surface not protruding from the side.

[0009] As a preferred embodiment, the standard straight beam is positioned after the center placement section, and at least one side is parallel to the horizontal plane.

[0010] To ensure the accuracy of the angle sensor readings, the angle sensor is positioned horizontally relative to the mounting side of the standard straight beam.

[0011] For ease of use, the cross-section of the standard straight beam is square.

[0012] To accommodate track gauges of different specifications, one end of the standard straight beam can be detachably equipped with an extension attachment, and each side of the extension attachment is provided with a corresponding insertion part.

[0013] As a preferred embodiment, the midpoint of the insertion portion on each side of the extension attachment and the midpoint of the insertion portion on each side of the standard straight beam away from the extension attachment are located on the same plane, and the standard straight beam is provided with multiple angle sensors at this position.

[0014] The specific detection and reading method is that both the track gauge measuring mechanism and the superelevation measuring mechanism are equipped with grating rulers and reading heads.

[0015] The beneficial effects of this utility model are as follows: This utility model is a multifunctional track gauge grating calibration device. Based on the existing calibration equipment, the original standard frame is improved by making it a regular polygonal standard straight beam design, which can meet the needs of setting angle sensors and plug-in parts on different sides. Therefore, in use, only the standard frame needs to be rotated to calibrate the track gauge at different lengths. Moreover, this method is better than repeated calibration. In addition, for the different track gauge settings in different regions of China, an extension attachment is set to expand the calibration range and improve the adaptability of the equipment.

[0018] Example 1 like Figure 1 , 2 The multifunctional track gauge grating calibration device shown includes a mounting platform 1. The upper surface of the mounting platform 1 is flat, and a track gauge measuring mechanism 2 and a superelevation measuring mechanism 3 are spaced apart on the upper surface, respectively used to measure distance and superelevation parameters. Specifically, the track gauge measuring mechanism 2 is equipped with a horizontal adjustment seat 21 that can move in the horizontal plane. In this way, the distance parameter can be calibrated. For this purpose, the direction of movement of the horizontal adjustment seat 21 is away from or towards the superelevation measuring mechanism 3 to ensure that the distance between the two is the marked length after the standard frame 4 is set, which facilitates subsequent parameter comparison. Then, in order to calibrate the superelevation parameter, the superelevation measuring mechanism 3 is equipped with a vertical adjustment seat 31 that can move in the vertical direction. After the height of the vertical adjustment seat 31 changes, it can tilt to simulate the superelevation state. It should be noted that when the vertical adjustment seat 31 is in the lowest position, it can be located on the same horizontal plane as the horizontal adjustment seat 21 to ensure the accuracy of the distance calibration.

[0019] Furthermore, the specific detection and reading method of the above structure is as follows: both the track gauge measuring mechanism 2 and the ultra-high measurement mechanism 3 are equipped with grating rulers and reading heads, which can be read through gratings, and the accuracy is higher than that of manual scale recognition.

[0020] For example Figure 5As shown, a center placement part 211 and a side placement part 212 are respectively provided above the horizontal adjustment seat 21 and the vertical adjustment seat 31. The center placement part 211 is used to set the standard frame 4, while the side placement part 212 is used to set the track gauge. The side placement parts 212 can be symmetrically arranged on both sides of the center placement part 211 as needed. In this way, the verification and comparison of parameter values ​​and the acquisition of error values ​​can be performed.

[0021] Finally, based on the above structure, the main feature of this device is that the standard frame 4 includes a standard straight beam 41 with a cross-section of a regular polygon, and the number of sides of the polygon is even. The regular polyhedral structure allows the standard straight beam 41 to have multiple sides. Therefore, a corresponding plug-in part 42 structure can be set on each side. In order to perform ultra-high detection, an angle sensor 43 is set at the center position of each side of the standard straight beam 41, and a plug-in part 42 that cooperates with the center placement part 211 is symmetrically set at both ends of each side. If the number of sides of the polygon is odd, an angle sensor 43 needs to be set on the symmetrical edge of each side to ensure that the angle change value can be read normally.

[0022] In order to change the length parameters for calibration of the gauge, the insertion part 42 on each side of the standard straight beam 41 has a different distance from the center position. The calibration length can be changed by using the insertion part 42 at different length positions in conjunction with the center placement part 211. This allows the gauge to be calibrated to change vertically after the length changes, and it is also convenient to count the errors under different specifications.

[0023] The above structure can achieve the following: according to actual needs, the existing standard frame 4 can be modified to have symmetrical plug-in parts 42 at multiple length positions. Therefore, the gauge can be calibrated after the length is changed, and it can be achieved simply by rotating the standard frame 4. The operation is convenient and simple, and there is no need to configure more standard frame 4 structures of different specifications. In addition, the spacing of the plug-in parts 42 on each side of the designed standard frame 4 is a standard value to ensure the accuracy of the calibration standard parameters.

[0024] It should be noted that in the above structure, to avoid mutual interference, the two ends of the insertion part 42 of the standard straight beam 41 do not extend outward relative to the side surface, such as... Figure 4 As shown, this method ensures that each plug-in portion 42 can be properly positioned with the center placement portion 211 without being obstructed by other structures.

[0025] Furthermore, for ease of use, the standard straight beam 41 has a square cross-section, and four insertion parts 42 with specified spacing in the positive direction are sufficient to meet the requirements. In addition, the square device is easy to use and place, and is easy to process.

[0026] Next, regarding the actual usage effect, to avoid obstruction of rotation, the standard straight beam 41 is provided with a mounting groove, and the angle sensor 43 is placed in the mounting groove, with its upper surface not protruding from the side it is located on. Figure 5 As shown, this method ensures that the angle sensor 43 can read normally and will not be obstructed during rotation. Since there are many angle sensors 43, the verticality of the vertically upward angle sensor 43 can be used as the reference each time, which is convenient for reading.

[0027] Based on practical needs and to ensure the accuracy of the calibration, the standard straight beam 41 is positioned after being placed in the center position 211, with at least one side parallel to the horizontal plane. Furthermore, to ensure the accuracy of the angle sensor 43 readings, the angle sensor 43 is horizontally positioned relative to the mounting side of the standard straight beam 41. In this configuration, it is sufficient to ensure that the horizontal adjustment seat 21 and the vertical adjustment seat 31 are on the same horizontal plane to ensure that the standard frame 4 placed on it is horizontal. In this case, the distance difference can be calibrated. Moving the vertical adjustment seat 31 upwards allows for the calibration of the height difference.

[0028] Example 2 In addition to the same structure as in Embodiment 1, given the various track gauge conditions in China, a single standard frame 4 is insufficient. However, since there are relatively few wide-gauge gauge calibrations, directly installing a standard frame 4 would not only result in a heavy standard frame 4 but also be inconvenient to use. Therefore, in addition to the same structure as in Embodiment 1, to accommodate different gauge gauge specifications, one end of the standard straight beam 41 can be detachably equipped with an extension attachment 44. The extension attachment 44 can be fixed via plug-in or other connection methods, used to extend the standard frame 4 in special circumstances. Furthermore, each side of the extension attachment 44 is provided with a corresponding plug-in portion 42, such as... Figure 3 , 6 As shown, the inspection length can be extended by this extension method, and the aforementioned extension attachment 44 also needs to be provided with multiple plug-in portions 42 to meet the situation of changing distance.

[0029] Specifically, the midpoints of the insertion portions 42 on each side of the extension attachment 44 and the insertion portions 42 on each side of the standard straight beam 41 away from the extension attachment 44 are located on the same plane, and multiple angle sensors 43 are provided at this position on the standard straight beam 41. That is to say, only one side of the corresponding extension attachment 44 needs to be set, and symmetrical arrangement is not required. The extension attachment 44 can be used in conjunction with the insertion portion 42 at the far end of the standard frame 4 to which it is connected. In addition, in order to facilitate the ultra-high verification, the corresponding angle sensors 43 need to be set on the standard straight beam 41. The angle sensors 43 that are not frequently used can be distinguished by setting a cover plate or not powering on them to avoid normal readings.
