Description

Technical Field

[0001] This utility model relates to the field of train track technology, and in particular to a long-stroke track equipment positioning device and a high-speed train inspection robot. Background Technology

[0002] In the process of inspecting trains during operation, track inspection equipment often needs reliable positioning of the equipment's travel on the track to accurately grasp the trajectory of the control equipment and achieve precise detection. Ordinary positioning devices mostly consist of a simple motor with belts, gears, and other structures. The train's travel is calculated by measuring the number of motor rotations, thus determining the equipment's position on the track. However, this motor-based positioning method is easily affected by slippage or track wear, affecting positioning accuracy and even leading to positioning failure. Laser positioning devices are also used, offering very high accuracy. However, they require extremely high track flatness, and environmental dust can easily interfere with laser positioning, limiting their applicability. Utility Model Content

[0016] Figure 2 This is a right-side view of the structural schematic diagram of the long-stroke track positioning device of this utility model. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0018] like Figures 1 to 2 As shown, this is the first embodiment of the present invention, which provides a high-speed train inspection robot (not shown) for track (not shown) inspection, which includes a robot body (not shown) and a track long-stroke equipment positioning device 100.

[0019] The track is equipped with a meshing rack (not shown), the robot body is mounted on the track, and the long-stroke track positioning device 100 is mounted on the robot body and connected to the track drive. Specifically, in this embodiment, a mounting box (not shown) is provided on one bottom side of the robot body, and the long-stroke track positioning device 100 is mounted in the mounting box, wherein the meshing gear 30 extends out of the mounting box and meshes with the meshing rack. The mounting box structure on the robot body can effectively protect the long-stroke track positioning device 100 and prevent damage to the device due to bumps or other factors during robot travel and testing.

[0020] The long-stroke track positioning device 100 includes a mounting base 10, a rocker arm 20, a meshing gear 30, an encoding device 40, and a retaining spring 50. The mounting base 10 is located on one side of the track and is also equipped with a sliding guide rail 11. One end of the rocker arm 20 is axially connected to the mounting base 10 and can rotate movably. The other end of the rocker arm 20 is engaged with the sliding guide rail 11 and can slide along the sliding guide rail 11. The meshing gear 30 and the encoding device 40 are both mounted on the rocker arm 20. The meshing gear 30 is also meshed with a rack, and the encoding device 40 is belt-driven connected to the meshing gear 30. The retaining spring 50 is horizontally positioned, and its two ends are respectively abutted against the mounting base 10 and the rocker arm 20.

[0021] As the train travels on the track, the positioning device installed on the train activates. Whenever the train moves on the track, the meshing gear 30 rotates relative to the meshing rack. The meshing gear 30, connected to the meshing rack, accurately and clearly records the train's journey on the track, preventing errors caused by slippage of the rubber wheels. This journey is then further precisely calculated by the encoding device 40, enabling the positioning device to accurately locate the train's position. The positioning accuracy of the encoding device 40 is significantly higher than that of a conventional motor.

[0022] The rocker arm 20 includes a main arm 21, a rocker shaft 22, a sliding seat 23, and a deflection shaft 24. The main arm 21 is located above the mounting base 10. The rocker shaft 22 is vertically inserted through the right end of the main arm 21, and its lower end is fixedly mounted on the mounting base 10. The main arm 21 can rotate along the rocker shaft 22. The sliding seat 23 is engaged with the sliding guide rail 11 and can slide along the sliding guide rail 11. The deflection shaft 24 is fixedly mounted on the upper end of the sliding seat 23 and is also axially connected to the bottom left end of the main arm 21. The main arm 21 can deflect along the deflection shaft 24.

[0023] After a train travels on the track for an extended period, the track itself is prone to slight misalignment. Conventional positioning devices employ a fixed structure, and their steel wheels, rubber wheels, gears, etc., originally connected to the track drive, can easily detach from the track, causing the normal positioning function to fail. However, the multi-joint rocker arm 20 structure designed in this application, in conjunction with a retaining spring 50, enables the meshing gear 30 mounted on the rocker arm 20 to have dynamic elastic adjustment capability. Even if the position between the track and the meshing gear 30 changes, the retaining spring 50 will use its elasticity to adjust the rocker arm 20, thereby keeping the meshing gear 30 always pressed against the meshing rack of the track, preventing separation and ensuring proper positioning.

[0024] Understandably, this utility model also has a second embodiment, which is basically the same as the first embodiment, except that: in the second embodiment, the long-stroke track equipment positioning device 100 further includes a motor (not shown) and a measuring sensor (not shown). The motor is connected to the track drive, and the measuring sensor is connected to the motor signal. The long-stroke track equipment positioning device 100 also includes a positioning terminal (not shown), which includes an encoder positioning module (not shown), a motor positioning module (not shown), and a data verification module (not shown). The encoder positioning module is connected to the encoder device 40 signal, the motor positioning module is connected to the measuring sensor signal, and the data verification module is connected to both the encoder positioning module and the motor positioning module signal.

[0025] The motor connected to the track drive rotates synchronously during train operation, and together with the measuring sensors, it records and measures the train's journey. The encoder positioning module and motor positioning module in the positioning terminal receive signals from the encoder 40 and the measuring sensors, respectively, to obtain the train positioning data calculated by each. The data verification module compares and verifies the positioning data measured by the encoder 40 with the positioning data measured by the motor, further ensuring the reliability of the train positioning.

[0026] In summary, the beneficial effects of this utility model of a long-stroke track equipment positioning device 100 and a high-speed train inspection robot are as follows: Firstly, by designing a positioning device with an encoding device 40, the accuracy of track positioning is significantly improved. Secondly, the positioning device is designed with an elastic rocker arm 20 mechanism, enabling it to adapt to various track shapes and greatly enhancing the applicability of the positioning device. Thirdly, the positioning device is also equipped with a motor that performs synchronous measurement and positioning with the encoding device 40, and the data verification module in the positioning terminal further enhances the reliability of the positioning function. Fourthly, this utility model is highly practical and has significant potential for widespread application.

[0027] The embodiments described above illustrate only one implementation of the utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be determined by the appended claims.
