[0027] See also Figures 1 to 5 , shown is a track detection device in an embodiment of the present invention, including a track detector and a profile detection mechanism 20.

[0028] The track inspection instrument includes a track inspection instrument body 12 and two track inspection beams 11 disposed on opposite sides of the track inspection instrument body 12. The track inspection beam 11 includes a beam body 11a and a running wheel assembly 11b disposed on one side of the beam body 11a. Specifically, in this embodiment, the running wheel assembly 11b includes a running wheel 11b disposed at the bottom of the beam body 11a and a track gauge measuring wheel 11c disposed on the side of the beam body 11a.

[0029] The profile detection mechanism 20 includes a profile detection module 21 disposed between the two track inspection beams 11, and a hinge structure is provided between the profile detection module 21 and the track inspection beams 11. The profile detection module 21 includes an outer shell and a camera module disposed in the outer shell.

[0030] The hinge structure includes a rotating frame 22 provided on one side of the profile detection module 21, a hinge rod 23 rotatably provided in the rotating frame 22, and a hinge seat provided on one side of the track inspection beam 11, the hinge seat includes a mounting seat 43 provided on one side of the beam body 11a, and a clamping seat 44 movably provided on one side of the mounting seat 43, the mounting seat 43 is provided with a receiving groove 43c corresponding to the hinge rod 23, the clamping seat 44 is used to abut against the hinge rod 23 to fix the hinge rod 23 in the receiving groove 43c, the profile detection mechanism 20 also includes a single-sided walking wheel 11b provided on one side of the bottom of the profile detection module 21, the single-sided walking wheel 11b is provided on the side of the profile detection module 21 away from the hinge structure.

[0031] Preferably, in this embodiment, the profile detection mechanism 20 also includes a gauge following structure, and the gauge following structure includes a connecting plate 34 arranged on one side of the gauge measuring wheel 11c, a slide rail 41 is fixed to one side of the beam body 11a, and the mounting seat 43 is slidably arranged on the beam body 11a through the slide rail 41, and the connecting plate 34 is connected to the mounting seat 43.

[0032] By fixing a slide rail 41 on one side of the beam body 11a, the mounting seat 43 is slidably arranged on the beam body 11a through the slide rail 41, and the connecting plate 34 is provided on one side of the gauge measuring wheel 11c, so that the connecting plate 34 is connected to the above-mentioned mounting seat 43, and the gauge measuring wheel 11c on the track inspection instrument is used to drive the mounting seat 43 and the profile detection module 21 on the mounting seat 43 to move. Compared with the profile detection equipment equipped with positioning wheels in the prior art, the equipment structure is simplified, it is convenient for transportation and use, and the detection efficiency is further improved.

[0033] Specifically, the mounting base 43 includes a side plate portion 43a positioned near the beam body 11a. A slider 42 corresponding to the slider 41 is provided on the side of the side plate portion 43a near the slide rail 41. A mounting portion 43b is provided on the side of the side plate portion 43a away from the slider 42. The receiving groove 43c is defined within the mounting portion 43b. Specifically, the main body of the mounting portion 43b comprises two sections, one located on opposite sides of the side plate portion 43a and corresponding to the ends of the hinge rod 23.

[0034] In some embodiments, the rotating frame 22 is provided with a through-groove, within which is disposed a sleeve corresponding to the hinge rod 23. The hinge structure further includes a bearing 25 disposed on one side of the sleeve, and the hinge rod 23 is rotatably mounted on the rotating frame 22 via the bearing 25. In some application scenarios of this embodiment, the rotating frame 22 is fixed to the outer housing of the profile detection module 21 via bolts, and the through-groove is disposed at the rear end of the rotating frame 22.

[0035] Furthermore, the hinge structure further includes a limiting structure provided between the hinge rod 23 and the bearing 25 , and the limiting structure includes a bearing nut 24 provided on one side of the bearing 25 .

[0036] In some application scenarios of this embodiment, by setting the above-mentioned bearing nut 24, the axial clearance can be eliminated to prevent the gap between the hinge rod 23 and the bearing 25 from causing movement, so as to avoid the rotating frame 22 and the profile detection module 21 on the side of the fixed bearing 25 from swinging left and right during walking, thereby meeting the measurement posture requirements.

[0037] Preferably, in some embodiments, the clamping seat 44 is rotatably mounted on one side of the mounting portion 43b via a rotating shaft 44c. The clamping seat 44 includes a pressing portion 44a fixed to one side of the rotating shaft 44c. The pressing portion 44a is provided with an inserting portion 44b at one end away from the rotating shaft 44c. The mounting portion 43b is provided with a slot 43d corresponding to the inserting portion 44b. By inserting the inserting portion 44b into the slot 43d and locking it, the pressing portion 44a can be used to press and secure the hinge rod 23 in the receiving groove 43c.

[0038] Specifically, in this embodiment, the plug-in portion 44b is threadedly connected to the pressing portion 44a, the slot 43d is provided with a threaded groove corresponding to the plug-in portion 44b, and the end of the plug-in portion away from the slot is provided with a handle 44d. In some application scenarios of this embodiment, the plug-in portion 44b is moved to the slot 43d using the rotating shaft 44c. Then, by rotating the handle 44d, the plug-in portion 44b is driven by the thread to move into the slot 43d and threadedly connect with the slot 43d, thereby securing the plug-in portion 44b.

[0039] Furthermore, a torsion spring 44e is sleeved on the rotating shaft 44c, with the two ends of the torsion spring 44e respectively connected to the pressing portion 44a and the mounting portion 43b. The torsion spring 44e is used to force the pressing portion 44a to move away from the receiving slot 43c when the plug-in portion 44b is disengaged from the slot 43d. For ease of understanding, in some application scenarios of this embodiment, when the handle 44d is rotated to disengage the plug-in portion 44b from the slot 43d, the pressing portion 44a swings along the rotating shaft 44c as the rotation point toward the side away from the receiving slot 43c under the action of the torsion spring 44e, and continues to remain in an open state, which can facilitate the disassembly of the hinge rod 23 and the next assembly and use.

[0040] In addition, in this embodiment, the running wheel assembly 11b further includes a fixed block 31 disposed on one side of the bottom of the beam 11a, a guide rod disposed on one side of the fixed block 31, and a spring 32 sleeved on the guide rod. The gauge measuring wheel 11c includes a movable block 33 sleeved on one side of the guide rod and a wheel body disposed on one side of the bottom of the movable block 33. The ends of the spring 32 are respectively connected to the fixed block 31 and the movable block 33. One side of the connecting plate 34 is connected to the movable block 33. In some applications of this embodiment, the tension of the spring 32 keeps the gauge measuring wheel 11c in contact with the side of the track. As the track gauge changes, the movable block 33 moves along the guide rod, thereby moving the connecting plate 34 at one end of the movable block 33, thereby moving the profile detection module 21. This ensures that the relative position of the profile detection module 21 and the track is fixed during measurement, simplifies data processing, improves test accuracy, and ensures that the viewing angle of the profile detection module 21 is always directly above the track, thus greatly maximizing the effective measurement range.

[0041] In summary, the track detection device in the above embodiment of the present invention is provided with a track detector, and a profile detection mechanism 20 is mounted on one side of the track detector by providing a hinge mechanism. One end of the profile detection module 21 is provided with a single-sided running wheel 11b, and the other side is connected to the track inspection beam 11 through a hinge mechanism. The running wheel 11b on one side is cancelled, so that the profile detection module 21 with the camera module is integrated into the track inspection instrument. The profile detection modules 21 on both sides do not need to be connected with a beam, and the height of the hinge structure is determined by the size of the track inspection beam 11. , thereby ensuring the levelness of the profile detection module 21. By setting the hinge rod 23, the profile detection module 21 can rotate relative to the mounting seat 43, so that the single-side running wheel 11b always falls on the rail surface and will not be suspended due to the uneven rail surface. This ensures the integration of the profile detection module 21 and the track inspection instrument and their postures do not affect each other, making it convenient to simultaneously obtain parameters such as the geometric dimensions and profile status of the track, thereby improving the detection efficiency. At the same time, by integrating the track inspection instrument and the profile detection equipment, the equipment structure is simplified, which is convenient for transportation and use, and further improves the detection efficiency.
