[0026] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] like Figure 1 As shown, a track measuring vehicle includes a measuring vehicle body 2, a movable connecting seat 3, rollers, a traction rope 6, a measuring device, and a signal harness 62. The measuring vehicle body 2 is linearly and vertically distributed between two tracks 1. The movable connecting seat 3 is fixed to the end of the measuring vehicle body 2 and matches the corresponding track 1, thereby supporting the measuring vehicle body 2 and enabling it to move along the track 1. The rollers are fixedly connected to the bottom of the movable connecting seat 3 and slidably connected to the track 1. The traction rope 6 is connected to the measuring vehicle body 2 and is used to traction the measuring vehicle body 2 to move along the track 1 under external force. The measuring device is fixed to the upper side of the measuring vehicle body 2 and measures track 1 data. The signal harness 62 is connected to the measuring device at one end and extends along the traction rope 6 at the other end, transmitting the measurement data acquired by the measuring device to an external system such as an onboard unit. This data is then used to automatically generate a track 1 quality assessment report through an algorithm, supporting visual charts and anomaly point location, thus achieving the effect of an intelligent data platform.

[0028] In this embodiment, the measuring device integrates advanced sensing technology and a data acquisition system, and together with the installed sensors, it can monitor key indicators such as the lateral level and smoothness of track 1 in real time, providing a scientific basis for railway construction, daily maintenance and safe operation, and improving the safety of vehicle movement on track 1.

[0029] like Figure 1 , Figure 2 , Figure 3As shown, the measuring vehicle body 2 is an aluminum alloy tubular body, and an L-shaped connector for detachable connection and fixation is provided between it and the movable connecting seat 3. Therefore, this track measuring vehicle has the advantages of being lightweight and high-strength, with a comprehensive deformation of less than 1mm. The measuring device includes an angle sensor 5 for real-time acquisition of the height difference between the left and right tracks 1. The high-precision angle sensor 5 is used to acquire the height difference between the left and right tracks 1 in real time, so as to achieve the purpose of measuring key indicators such as the lateral level and smoothness of the track 1.

[0030] Meanwhile, a storage hook 21 is provided on the top of the measuring vehicle body 2 for cable storage. A handle 31 is provided on the top of the movable connecting seat 3, with a through hole 32 in the middle for mounting and fixing the rollers and the measuring vehicle body 2. Therefore, this track measuring vehicle has the advantages of convenient cable harness and wire rope storage, hanging and fixing, and convenient handling with the handles 31 on both sides.

[0031] It should be mentioned that the rollers are modular rollers 4, and the bottom is equipped with coaxially distributed contact wheels 41 and limiting wheels 411. The contact wheels 41 are used to contact the upper side of the track 1, and the limiting wheels 411 are used to contact the inner side of the track 1. Furthermore, the modular rollers 4 achieve stable contact with the track 1 through wear-resistant nylon and a double bearing structure, while reducing lateral friction during pushing and extending the service life of the track measuring vehicle.

[0032] like Figure 1 , Figure 4 As shown, a figure-eight buckle is provided at one end of the guide rope, allowing for free traction angle and preventing abnormal phenomena such as jamming, obstruction, and jumping during the towing of the track measuring vehicle. The figure-eight buckle is connected to a towing hook 61 for connection with the measuring vehicle body 2, thus forming a stable drive connection structure. Meanwhile, a corrugated flexible hose is sleeved on the traction rope 6, and one end of the signal harness 62 passes through the corrugated flexible hose, thus protecting the signal harness 62. A plug-in connector 63 is provided on the top of the measuring vehicle body 2. The other end of the signal harness 62 is used to plug into and fix to the plug-in connector 63, and the measuring device is wiredly connected to the plug-in connector 63. The plug-in connector 63 improves the connection stability of the signal harness 62 and facilitates disassembly and assembly.

[0033] In summary, this application provides a track measuring vehicle. The track measuring vehicle has a measuring vehicle body 2 vertically distributed between two tracks 1, and uses rollers to move the measuring vehicle body 2 along the two tracks 1. In addition, while the measuring vehicle body 2 is pulled by the external force of the traction rope 6, the signal harness 62 transmits the track 1 data measured by the measuring device to an external system to obtain a test report, thereby achieving the purpose of improving movement stability and measurement accuracy.
