Description

Technical Field

[0001] This utility model relates to the field of track detector technology, and in particular to a gyroscope adjustment device for a track detector. Background Technology

[0002] Railway track inspection instruments (track inspection machines) are used to measure the static geometric parameters of tracks. They typically employ two inertial sensors to continuously measure track smoothness, with the gyroscope being the core component of the sensor. The two gyroscopes measure the track's orientation and elevation respectively. The gyroscopes are mounted on the track inspection machine using a fixing device, and precise adjustments are made to ensure parallelism with both the transverse and longitudinal surfaces of the rails. After adjustment, calibration is performed. The installation of the gyroscopes requires high geometrical accuracy, as this directly affects the overall measurement accuracy of the track inspection machine.

[0003] The existing technology for gyroscope installation and adjustment has the following shortcomings:

[0004] 1. There are many installation and adjustment points, requiring multiple adjustments. This is done through frequent fine-tuning using auxiliary tooling and length measuring instruments (such as dial indicators, lever indicators, etc.), which is inefficient.

[0005] 2. The positioning reference is achieved by converting the measurement attitude reference plane, which generates a reference positioning error; when the gyroscope fails and needs to be repaired or replaced, the mounting device components need to be re-aligned. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a gyroscope adjustment device for a track detector, which aims to solve the technical problems of low installation efficiency caused by the large number of gyroscope installation and adjustment points and the need for recalibration when replacing the gyroscope, as well as the technical problems of easy error in the conversion of the positioning reference.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0008] A gyroscope adjustment device for a track detector, the track detector including a track detector body, the gyroscope adjustment device including an orthogonal bracket detachably connected to the track detector body, the orthogonal bracket including a horizontal base frame and a vertical base frame arranged orthogonally to each other, the horizontal base frame having three through holes, each through hole having a bolt, the orthogonal bracket being connected to the track detector body by the bolts, the track detector also including two gyroscopes, the two gyroscopes being detachably fixedly connected to the horizontal base frame and the vertical base frame respectively, the gyroscope adjustment device of the track detector also including a reference platform for providing a reference plane for the track detector.

[0009] According to one aspect of the above technical solution, the two gyroscopes are respectively a first gyroscope connected to the horizontal base and a second gyroscope connected to the vertical base. The horizontal base includes a first mounting surface for fixing the first gyroscope, and the vertical base includes a second mounting surface for fixing the two gyroscopes. The first mounting surface and the second mounting surface are orthogonal to each other.

[0010] According to one aspect of the above technical solution, the track detector body includes two sets of parallel walking mechanisms and a central beam frame disposed between the two walking frames. The central beam frame is detachably connected to the two walking mechanisms, and the orthogonal support is disposed on the central beam frame.

[0011] According to one aspect of the above technical solution, an insulating sleeve that mates with the through hole is provided between the bolt and the orthogonal bracket.

[0012] According to one aspect of the above technical solution, an insulating pad is provided on the bolt. The insulating pad includes an upper insulating pad and a lower insulating pad. The upper insulating pad is located at the end of the bolt away from the middle beam frame, and the lower insulating pad is located between the orthogonal bracket and the middle beam frame to adjust the levelness of the orthogonal bracket.

[0013] According to one aspect of the above technical solution, the reference platform includes a marble platform assembly for providing a horizontal reference plane and a railway track inspection instrument calibration table for providing a vertical reference plane. The marble platform assembly includes a marble platform body and an equal-height pad that cooperates with the marble platform body.

[0014] According to one aspect of the above technical solution, the reference platform is a customized tooling.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. By mounting two gyroscopes onto the horizontal and vertical base sections of an orthogonal bracket, and utilizing the perpendicularity between the horizontal and vertical base sections, the two gyroscopes are made relatively orthogonal. This method also features convenient gyroscope replacement without the need for multiple fine-tuning adjustments, thus solving the problem of cumbersome installation processes in existing technologies where multiple fine-tuning and calibration adjustments are required for gyroscope installation and replacement.

[0017] 2. By placing the track inspection instrument body equipped with orthogonal brackets onto the marble platform assembly and railway track inspection instrument calibration table, which can provide a horizontal and vertical reference plane, the installation positions of the two gyroscopes in the track inspection instrument can be adjusted by finely adjusting the orthogonal brackets so that the first mounting surface of the horizontal base is parallel to the horizontal reference plane of the marble platform assembly, and the second mounting surface of the vertical frame is parallel to the vertical reference plane of the railway track inspection instrument calibration table.

[0018] 3. This adjustment method uses the horizontal and vertical reference planes provided by the marble platform assembly and the railway track inspection instrument calibration table to adjust the horizontal and vertical base frames of the orthogonal support. This effectively ensures that the mounting surfaces of the horizontal and vertical gyroscopes of the track inspection instrument are parallel to the transverse and longitudinal surfaces of the rail, respectively, during track inspection measurements. This replaces the previous method of adjusting only the internal components of the track inspection instrument, including the gyroscopes, eliminating intermediate conversion of the positioning reference, effectively eliminating repeated positioning errors, and improving the accuracy of the track inspection instrument's measurement data.

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0032] Please see Figure 1 and Figure 2 The first embodiment of this utility model provides a gyroscope adjustment device for a track detector. The track detector 1 includes a track detector body 11. The gyroscope adjustment device includes an orthogonal bracket 2 detachably connected to the track detector body 11. The orthogonal bracket 2 includes a horizontal base frame 21 and a vertical base frame 22 arranged perpendicularly to each other. The horizontal base frame 21 has three through holes 212, and bolts 23 are provided in the through holes 212. The orthogonal bracket 2 is connected to the track detector body 11 by the bolts 23. The track detector 1 also includes two gyroscopes 3, which are detachably fixedly connected to the horizontal base frame 21 and the vertical base frame 22, respectively. The gyroscope 3 adjustment device of the track detector 1 also includes a reference platform 4 for providing a reference surface for the track detector 1.

[0033] Please see Figure 3 and Figure 4In this embodiment, the orthogonal support 2 includes a horizontal base frame 21 and a vertical base frame 22. A first mounting surface 211 and a second mounting surface 221 are provided on the horizontal base frame 21 and the vertical base frame 22. Multiple threaded holes 26 are provided on the first mounting surface 211 and the second mounting surface 221. Both gyroscopes 3 are detachably fixed to the orthogonal support 2 by bolts 23 engaging with the threaded holes 26. Specifically, the two gyroscopes 3 are a first gyroscope 31 connected to the horizontal base frame 21 and a second gyroscope 32 connected to the vertical base frame 22. The horizontal base frame 21 includes components for fixing the... The first mounting surface 211 of the first gyroscope 31 and the vertical base frame 22 include a second mounting surface 221 for fixing the two gyroscopes 32. The first mounting surface 211 and the second mounting surface 221 are orthogonal to each other. It should be noted that, to facilitate rapid alignment of the two gyroscopes 3, both the first mounting surface 211 and the second mounting surface 221 are precision-machined to control the vertical accuracy of the machining, thereby ensuring that the gyroscopes 3 are orthogonal in the installation direction. This allows the gyroscopes 3 to achieve self-alignment after being mounted on the orthogonal bracket 2 without adjustment, and the installation is convenient. It should be noted that the orthogonal bracket 2 mentioned above can be manufactured by integral molding or by precision machining of multiple components. In this embodiment, the orthogonal bracket 2 is integrally molded, improving the orthogonal accuracy of the two gyroscopes 3 after installation.

[0034] In this embodiment, the track detector 1 is a modular design, including two sets of traveling mechanisms 111 and a central beam frame 112. Protruding positioning pins and fixing blocks are provided on both sides of the central beam frame 112, while the traveling mechanisms 111 have slots and latches that mate with the positioning pins and fixing blocks. During installation, the central beam frame 112 is positioned and connected to the traveling mechanisms 111 via the positioning pins, and then the central beam frame 112 is locked in place by the latches. Next, the orthogonal bracket 2 is placed on the central beam frame 112, completing the assembly of the track detector 1. Specifically, the track detector itself... The body 11 includes two sets of parallel walking mechanisms 111 and a central beam 112 disposed between the two walking frames 111. The central beam 112 is detachably connected to the two walking mechanisms 111. The orthogonal bracket 2 is disposed on the central beam 112. It should be noted that in this embodiment, the track detector body 11 is arranged in an I-shape. In practical applications, other structures are also applicable to the track detector body 11. It is worth noting that mounting holes for the orthogonal bracket 2 need to be reserved on the track detector body 11. In addition, since the track detector body 11 is assembled in a modular manner, after assembly, it will inevitably be unable to meet the alignment requirements of the gyroscope 3 on the orthogonal track in terms of accuracy, that is, further adjustment of the parallelism of the attitude reference plane is required.

[0035] Next, the assembled track detector 1 is placed on the reference platform 4 for the next step of attitude reference plane parallelism adjustment;

[0036] Please see Figure 1 and Figure 2 The first type of reference platform 4 provided by this utility model specifically includes a marble platform assembly 42 for providing a horizontal reference surface 423 and a railway track inspection instrument calibration platform 41 for providing a vertical reference surface 412. The marble platform assembly 42 includes a marble platform body 421 and a leveling block 422 that cooperates with the marble platform body 421. First, the track inspection instrument 1 of the orthogonal bracket 2 to be locked is placed on the marble platform body 421, and then the leveling block 422 is inserted. A horizontal reference surface 423 is formed by the upper end face of the leveling block 422, so that the track inspection instrument 1 is on a standard horizontal reference surface 423. Then, the first mounting surface 211 is made parallel to the horizontal reference surface 423 by adjusting the orthogonal bracket 2. Finally, After fixing the locking bolt 23, the horizontal reference plane 423 of the track detector 1 is adjusted. Next, the track detector 1 is removed from the marble platform assembly 42 and placed on the railway track inspection instrument calibration table 41. The railway track inspection instrument calibration table 41 is provided with two guide rail planes 411 and an adjustment mechanism for adjusting the height of the reference table. By adjusting the adjustment mechanism, the symmetrical center plane between the two guide rail planes becomes a vertical reference plane 412, so that the track detector 1 is in a standard vertical reference plane 412. Then, by adjusting the orthogonal bracket 2, the second mounting surface 221 is made parallel to the vertical reference plane 412, and the locking bolt 23 is fixed to complete the adjustment of the vertical reference plane 412 of the track detector 1, thereby completing the attitude adjustment of the gyroscope of the entire track detector 1.

[0037] like Figure 4In this embodiment, an insulating pad 25 is added between the orthogonal bracket 2 and the track detector body 11 to adjust the parallelism of the first mounting surface 211 and the second mounting surface 221 with the horizontal reference surface 423 and the vertical reference surface 412, thereby realizing the attitude of the gyroscope 3 on the top surface of the rail. After the orthogonal bracket 2 is adjusted, the locking bolt 23 is tightened to fix the orthogonal bracket 2 and the track detector body 11, thereby completing the adjustment of the parallelism of the attitude reference surface of the track detector 1. Finally, the two gyroscopes 3 are directly installed on the orthogonal bracket 2 to complete the installation of the entire track detector 1 and the adjustment of the gyroscopes 3. It should be noted that, since the gyroscope 3 needs to avoid interference from static electricity during operation, and the orthogonal support 2 and the central beam 112 are connected by bolts 23 with metallic properties, an insulating sleeve 24 and an insulating pad 25 are provided at the contact point between the bolt 23 and the orthogonal support 2. Specifically, an insulating sleeve 24 that mates with the through hole 212 is provided between the bolt 23 and the orthogonal support 2, and an insulating pad 25 is also provided on the bolt 23. The insulating pad 25 includes an upper insulating pad 251 and a lower insulating pad 252. The upper insulating pad 25 is located at the end of the bolt 23 away from the central beam 112, and the lower insulating pad 252 is located between the orthogonal support 2 and the central beam 112 to adjust the levelness of the orthogonal support 2.

[0038] In summary, the gyroscope adjustment device for the track detector in the above embodiments of this utility model, by pre-setting an orthogonal bracket on the track detector, then placing the track detector on the marble component and railway track inspection instrument calibration table, and using the standard horizontal and vertical reference planes provided by the marble component and railway track inspection instrument calibration table, the parallelism between the first and second mounting surfaces of the orthogonal bracket and the horizontal and vertical reference planes is adjusted, and finally the two gyroscopes are directly installed on the orthogonal bracket, the alignment and adjustment of the gyroscopes can be quickly completed. This improves the high measurement accuracy and efficiency of gyroscope adjustment of this utility model, and also makes the subsequent maintenance of the gyroscopes extremely convenient.

[0039] Another embodiment of the gyroscope adjustment device for a track detector provided by this utility model differs from the gyroscope adjustment device for a track detector in that: the reference platform is a customized fixture. By placing the track detector to be adjusted onto the customized fixture, the horizontal parallelism of the first mounting surface and the vertical parallelism of the second mounting surface of the orthogonal bracket of the track detector can be adjusted simultaneously. The adjustment steps are the same as those described above and will not be repeated here.
