[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0040] like Figures 1-7 As shown, this utility model embodiment provides an inspection device, which includes:

[0041] The system comprises a fixed frame 1, a traveling wheel assembly 2, and a detection device 3. Among these,

[0042] There are two walking wheel assemblies 2, which are arranged opposite to each other along the first direction. Each walking wheel assembly 2 includes a mounting plate 21 and a walking wheel 22. The two walking wheels 22 are located between the two mounting plates 21. The mounting plates 21 are movably arranged on the top of the fixed frame 1 along the first direction to adjust the distance between the two walking wheels.

[0043] The detection device 3 includes a detection equipment body 31, which is rotatably mounted at the bottom of the fixed frame 1, and the rotation axis of the detection equipment body 31 is in the vertical direction.

[0044] When the inspection device is in normal use, place the device under the track, adjust the distance between the two traveling wheel assemblies 2 so that the two traveling wheels 22 move to be close to both sides of the track, start the detection device 3 to adjust the inspection angle and complete the inspection. The adjustable setting of the two traveling wheel assemblies 2 makes the installation convenient and quick, and can be adapted to different sizes of tracks, with a wide range of applications. The setting of the detection device 3 makes the inspection angle adjustable, and the inspection work is more accurate and efficient.

[0045] Specifically, in this embodiment, the inspection device is applied to a track made of I-beams. Along the width of the track, a travel groove is provided on each side of the track, and two travel wheels 22 are movably disposed in the two travel grooves. When the inspection device is installed on the track, the distance between the two mounting plates 21 is adjusted so that the two travel wheels 22 can be embedded in the two travel grooves respectively.

[0046] Furthermore, the inspection device also includes an adjustment component 4, which is mounted on the fixed frame 1. The adjustment component 4 is connected to two mounting plates 21 respectively to adjust the distance between the two mounting plates 21.

[0047] Specifically, the adjustment assembly 4 includes a first motor 41, a bidirectional threaded rod 42, and a slide rod 43. The first motor 41 is fixedly installed on the outer wall of one side of the fixed frame 1. The bidirectional threaded rod 42 and the slide rod 43 are horizontally located inside the fixed frame 1. Both ends of the bidirectional threaded rod 42 are rotatably connected to the inner side of the fixed frame 1. The output end of the first motor 41 is fixedly connected to one end of the bidirectional threaded rod 42. The slide rod 43 is fixedly installed inside the fixed frame 1. The bidirectional threaded rod 42 includes a first threaded segment and a second threaded segment arranged sequentially along the axial direction. The thread directions of the first threaded segment and the second threaded segment are opposite. Two mounting plates 21 are threadedly connected to the first threaded segment and the second threaded segment, respectively. The slide rod 43 passes through the mounting plate 21.

[0048] When the inspection device is in normal use, when the traveling wheels 22 are located on both sides of the track, the first motor 41 is started. The first motor 41 drives the bidirectional threaded rod 42 to rotate. The bidirectional threaded rod 42 drives the two mounting plates 21 to move inward along the slide rod 43. The mounting plates 21 drive the traveling wheels 22 to move. The lower part of the traveling wheels 22 contacts the track to complete the installation. The distance between the two mounting plates 21 can be adjusted by rotating the bidirectional threaded rod 42 driven by the first motor 41. It can be conveniently installed from any position on the track and can also be adapted to tracks of different sizes.

[0049] Furthermore, the inspection device also includes a drive unit 5 and a transmission assembly 6. Among them,

[0050] The drive unit 5 is mounted on the fixed frame 1;

[0051] The transmission assembly 6 is disposed between the drive unit 5 and the two traveling wheels 22, and the drive unit 5 is driven to the two traveling wheels 22 through the transmission assembly 6.

[0052] Specifically, the drive unit 5 includes a dual-axis motor 51, and two transmission components 6 are provided. The two transmission components 6 are located on opposite sides of the two mounting plates 21. Each transmission component 6 includes a pulley frame 61, a pulley assembly 62, and a connecting shaft 63.

[0053] The pulley bracket 61 is mounted on the fixed frame 1;

[0054] The pulley assembly 62 includes a first pulley, a second pulley, and a belt. The first pulley and the second pulley are rotatably mounted on the pulley frame 61. The belt is sleeved on the first pulley and the second pulley. The two output shafts of the dual-axis motor 51 are respectively driven connected to the first pulleys of the two pulley assemblies 62.

[0055] One end of the connecting shaft 63 is coaxial with and fixedly connected to the traveling wheel 22, and the other end of the connecting shaft 63 is threaded on the second pulley, and the connecting shaft 63 is anti-rotationally engaged with the second pulley.

[0056] A spline is provided on the circumferential surface of the end of the connecting shaft 63 that is connected to the second pulley. The inspection device also includes a spline sleeve, which is set on the second pulley. The spline sleeve is coaxial with the second pulley and is fixedly connected to the second pulley. The spline sleeve is fitted on the outer end of the connecting shaft 63, and the spline sleeve and spline are anti-rotationally engaged.

[0057] When the inspection device is in normal use, the dual-axis motor 51 is started. The dual-axis motor 51 drives the first pulley of the pulley assembly 62 to rotate. The belt of the pulley assembly 62 drives the second pulley to rotate. The second pulley of the pulley assembly 62 drives the spline sleeve to rotate. The spline sleeve drives the connecting shaft 63 to rotate. The connecting shaft 63 drives the traveling wheel 22 to rotate along the track, thus moving the device. The arrangement of the connecting shaft 63 and the spline sleeve allows the mounting plate 21 to drive the traveling wheel 22 to move. The traveling wheel 22 drives the connecting shaft 63 to slide along the spline sleeve, ensuring that the second pulley of the pulley assembly 62 can drive the traveling wheel 22 to run synchronously when it rotates, avoiding problems caused by the inability to drive the device during adjustment and installation.

[0058] The inspection device also includes an auxiliary component 7, which includes two springs 71, a bracket 72 and two auxiliary wheels 73. The two springs 71 are located at the upper end of the fixed frame 1, and the two ends of the springs 71 are fixedly connected to the fixed frame 1 and the bracket 72 respectively. The two auxiliary wheels 73 are rotatably installed on the upper inner side of the bracket 72, and the auxiliary wheels 73 are in contact with the track.

[0059] The testing device 3 also includes a connecting frame 32, a second motor 33, a gear set 34, and a fixing plate 35. The connecting frame 32 is fixedly installed at the bottom of the fixing frame 1. The gear set 34 includes a driving gear and a driven gear that mesh with each other. Both the driving gear and the driven gear are rotatably installed at the bottom of the connecting frame 32. The second motor 33 is fixedly installed at the upper end of the connecting frame 32. The output end of the second motor 33 passes through the connecting frame 32 and is fixedly connected to one of the gears of the gear set 34. The driven gear is fixedly connected to the fixing plate 35. The lower end of the fixing plate 35 is fixedly connected to the main body 31 of the testing equipment.

[0060] When the inspection device is in normal use, it is installed by bringing the device close to the track from below, so that the auxiliary wheel 73 contacts the track and compresses the spring 71. During operation, the spring 71 always pushes the auxiliary wheel 73 upward, starting the second motor 33. The second motor 33 drives the drive gear of the gear set 34 to rotate, the drive gear drives the driven gear to rotate, and the driven gear drives the main body of the detection equipment 31 to rotate. Through the setting of the spring 71 and the auxiliary wheel 73, the spring 71 pushes the auxiliary wheel 73 to always be in contact with the track, avoiding the situation where the traveling wheel 22 will detach from the track and jump upward when passing over the uphill or downhill track, resulting in free spinning. The second motor 33 and the gear set 34 drive the main body of the detection equipment 31 to rotate, so that multi-angle detection can be performed during the inspection process, improving the detection effect.
