Description

Technical Field

[0001] This utility model relates to the field of gyroscope sensor testing technology, specifically to a rapid testing fixture for gyroscope sensors, suitable for the batch rapid testing of gyroscope sensors on a rail inspection trolley during rail fine-tuning in ballastless track systems. Background Technology

[0002] As a core infrastructure of high-speed railways, the smoothness of ballastless track systems directly determines the stability and safety of train operation. Track inspection trolleys are key data acquisition devices for rail fine-tuning, collecting geometric parameters such as track gauge, level, elevation, and orientation to provide precise data for fine-tuning plans. Track inspection trolleys that continuously collect data are generally called relative track inspection trolleys. These trolleys have built-in gyro sensors in the horizontal and vertical directions to acquire track angle change parameters in real time, making them a core component for achieving high-precision data acquisition. The gyro sensors are typically integrated into a gyro box and their angular accuracy performance must be verified through a dedicated calibration platform.

[0003] According to the industry standard "Verification Procedure for Railway Track Inspection Instruments" (TB / T 3147), gyroscope sensors need to undergo four tests in both forward and reverse directions (two tests per gyroscope, four tests for two gyroscopes). Existing gyroscope sensor testing fixtures have the following prominent problems: First, the clamping method mainly relies on bolt fastening or simple snap-fit, resulting in cumbersome assembly and disassembly processes. Clamping a single gyroscope sensor can take several minutes, failing to meet the rapid requirements of batch testing. Second, the tilt angle adjustment of the crossbeam frame lacks a calibration structure, making it difficult to guarantee the consistency of tilt angles across different batches or after long-term use, affecting test repeatability. Third, for multi-item sensors integrating directional and elevation gyroscopes, multiple disassemblies and reassemblies are required to switch test items, further reducing testing efficiency. These problems severely restrict the production and maintenance efficiency of gyroscope sensors. Utility Model Content

[0004] The purpose of this invention is to provide a rapid detection fixture for gyroscope sensors to solve the problems of time-consuming clamping, lack of calibration mechanism, and inconvenience in switching between multiple items in the existing technology.

[0005] The technical solution provided by this utility model is a rapid detection fixture for a gyroscope sensor, comprising:

[0006] The base is used to support the entire tooling.

[0007] The crossbeam is rotatably connected to the top of the base at one end, and abuts against the base at the other end via a replaceable calibration block;

[0008] An intermediate detection unit is located at the top center of the crossbeam frame, and its bottom is rotatably connected to the crossbeam frame via a vertical pivot. A detection platform is rotatably connected to the top of the intermediate detection unit via a rotating frame.

[0009] The bottom of the gyroscope box is fixedly connected to the top of the testing platform via a quick-connect structure;

[0010] The gyroscope box is composed of a connecting seat and a protective cover. The connecting seat is equipped with a horizontal detection seat and a vertical detection seat that are perpendicular to each other. The horizontal detection seat is fixed with a directional gyroscope to be tested, and the vertical detection seat is fixed with a height gyroscope to be tested. The gyroscope box is configured such that the angular positions of the two gyroscopes are interchanged and the test items are interchanged after the detection platform is flipped.

[0011] As a preferred embodiment of this invention, the quick-connect structure includes a dovetail block disposed above the detection platform and a dovetail slot disposed at the bottom of the gyroscope box. The dovetail block and the dovetail slot are inserted and fixed together. A movable locking block is attached to one side of the dovetail slot, and the locking block is adjustable by a locking screw. When the dovetail slot is inserted into the dovetail block, the position of the locking block can be adjusted by turning the locking screw, thereby adjusting the width of the dovetail slot, so that the bottom of the gyroscope box is locked to the dovetail block by the locking block.

[0012] As a preferred technical solution of this utility model, a positioning pin is provided on one side of the rotating frame. When the detection platform is rotated 90° by the rotating frame, the detection platform is vertically positioned by inserting the positioning pin.

[0013] As a preferred technical solution of this utility model, a horizontal positioning block for support is provided below the side opposite to the rotating connection between the rotating frame and the detection platform. The horizontal positioning block enables the rotating frame to remain horizontal under normal conditions.

[0014] As a preferred technical solution of this utility model, the detection platform is provided with an auxiliary handle on one side above the horizontal positioning block for easy angle adjustment.

[0015] As a preferred technical solution of this utility model, the calibration block is a height-fixing block for calibrating the height. The base is provided with a corresponding positioning slot at the calibration block. The calibration block is inserted and fixed through the positioning slot, so that the calibration block can increase the height of one side of the bottom of the crossbeam frame, and adjust the crossbeam frame to the specific horizontal tilt angle for measurement.

[0016] As a preferred technical solution of this utility model, a contact pad is fixed at the bottom of the crossbeam frame at the calibration block. The contact pad protrudes from the bottom of the crossbeam frame and abuts against the upper surface of the positioning slot under normal conditions, so that the crossbeam frame is in a horizontal state.

[0017] In a preferred embodiment of this invention, the base is provided with multiple adjustable feet for adjusting the height. The height is adjusted by means of threads on the adjustable feet.

[0018] As a preferred technical solution of this utility model, the directional gyroscope and the elevation gyroscope are the same gyroscope to be tested. After the detection platform is flipped, the positions of the two are interchanged and the detection items are interchanged.

[0019] The advantages of this utility model compared with the prior art are as follows:

[0020] 1. This utility model achieves second-level clamping of the gyroscope box by guiding the dovetail block and dovetail slot, combined with the locking mechanism of the locking block and locking screw, which greatly improves the detection efficiency.

[0021] 2. The detection platform of this utility model achieves precise locking of horizontal and vertical states through positioning pins and horizontal positioning blocks, and the auxiliary handle facilitates angle adjustment, ensuring the accuracy of the detection position;

[0022] 3. This utility model achieves standardized calibration of the tilt angle of the crossbeam frame through calibration blocks and positioning slots, and the contact pads ensure normal horizontality, thereby improving the repeatability of the test.

[0023] 4. This utility model allows the detection platform to rotate 90° through the rotating frame of the intermediate detection unit, so that the directional gyroscope and the high and low gyroscope in the gyroscope box can be interchanged, and the detection items can be switched without re-clamping.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components.

[0034] Example 1:

[0035] As per the instruction manual Figure 1-6 As shown, the present invention provides a rapid testing fixture for a gyroscope sensor, comprising a base 1, a crossbeam frame 2, an intermediate testing unit 4, and a gyroscope box 8.

[0036] In this embodiment, the base 1 serves as the foundation of the tooling. The height of the base 1 is adjusted to be level with the entire tooling by screwing in / out the threads on the triangularly shaped adjusting feet 24 at the bottom. One end of the crossbeam 2 is rotatably connected to the base 1 via a pin, and the other end rests on the calibration block 3. Wherein:

[0037] Routine inspection (horizontal direction): Remove the calibration block 3 from the positioning slot 22, and the contact pad 23 at the bottom of the crossbeam frame 2 abuts against the upper surface of the positioning slot 22, keeping the crossbeam frame 2 horizontal;

[0038] Tilt detection (height direction): Replace the calibration block 3 with the corresponding height, increase the height of one side of the crossbeam frame 2, and tilt it to a specific measurement angle (such as 10° or 15°) to meet the tilt detection requirements of the height gyroscope 14.

[0039] In this embodiment, the intermediate detection unit 4 is rotatably connected to the top of the crossbeam frame 2 via a vertical pivot 5. The detection platform 7 is connected to the top of the intermediate detection unit 4 via a rotating frame 6, enabling 360° rotation around the vertical pivot. One end of the detection platform 7 is rotatably connected to the top of the intermediate detection unit 4 via the rotating frame 6 (single-sided rotating shaft).

[0040] Under normal conditions, the horizontal positioning block 20 supports the rotating frame 6, keeping the testing platform 7 horizontal;

[0041] When vertical testing is required, rotate the testing platform 7 to 90° with the rotating frame 6 as the center, insert the positioning pin 19 into the positioning hole on one side of the rotating frame 6 to achieve vertical positioning of the testing platform 7 and ensure accurate angle. The testing platform 7 is provided with an auxiliary handle 21 on the side above the horizontal positioning block 20 for easy manual adjustment of the rotation angle.

[0042] In this embodiment, the gyroscope box 8 consists of a connecting base 9 (with a horizontal detection base 11 and a vertical detection base 12 perpendicular to each other) and a protective cover 10 (with a handle on top for easy carrying). The directional gyroscope 13 is fixed on the horizontal detection base 11, and the elevation gyroscope 14 is fixed on the vertical detection base 12. The directional gyroscope 13 and the elevation gyroscope 14 are the same gyroscopes to be tested. After the detection platform 7 is flipped, their positions are interchanged and the test items are interchanged. The dovetail slot 16 at the bottom of the gyroscope box 8 is inserted into the dovetail block 15 of the detection platform 7. Tightening the locking screw 18 pushes the locking block 17, reducing the width of the dovetail slot 16, so that the gyroscope box 8 is tightly locked to the detection platform 7. Tightening the locking screw 18 in the opposite direction can remove the gyroscope box 8. During the test, the vertical shaft 5 of the intermediate detection unit 4 rotates, driving the gyroscope box 8 to rotate, thus completing the angle accuracy test.

[0043] After the test is completed in this embodiment, the rotating frame 6 is reversed to rotate the test platform 7 back to its original position or rotate it 90°. At this time, the directional gyroscope 13 and the high and low gyroscope 14 in the gyroscope box 8 exchange positions, and the test items are automatically switched. There is no need to re-clamp the gyroscope box 8 and directly proceed to the next test item.

[0044] Working principle

[0045] 1. Initial state: The gyroscope box 8 is quickly fixed on the detection platform 7 through the quick-connect structure. The dovetail block 15 and the dovetail slot 16 provide guidance. The locking block 17 and the locking screw 18 ensure a firm clamping. The horizontal positioning block 20 supports the detection platform 7 to keep it horizontal. The crossbeam frame 2 is in a horizontal state.

[0046] 2. Horizontal detection of directional gyroscope 13: Rotate the intermediate detection unit 4 (through the vertical shaft 5) to drive the directional gyroscope 13 to rotate, and complete the horizontal angle accuracy detection.

[0047] 3. Altitude and low detection of directional gyroscope 13: Lift one end of the crossbeam frame 2, insert the calibration block 3 to adjust the tilt angle of the crossbeam frame 2, and the altitude and low gyroscope 14 will tilt with the gyroscope box 8 to complete the altitude and low direction detection;

[0048] 4. Gyroscope position swapping and secondary inspection: Rotate the inspection platform 7 to 90° (fixed by positioning pin 19). At this time, the directional gyroscope 13 and the high-low gyroscope 14 swap positions (directional gyroscope 13 rotates to the vertical position, and high-low gyroscope 14 rotates to the horizontal position), realizing a quick switch of inspection items. Since the calibration block 3 at the bottom of the crossbeam frame 2 has not been removed, the high-low direction inspection can be completed directly after the directional gyroscope 13 rotates to the vertical position. Then remove the calibration block 3 and reset the crossbeam frame 2. Rotate the middle inspection unit 4 again to complete the horizontal direction angle after the high-low gyroscope 14 rotates to the horizontal position. This completes the remaining two inspections of the two gyroscopes.

[0049] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
