Description

Technical Field

[0001] This utility model relates to the field of track bed-subgrade defect detection technology, and in particular to a railway ballast track bed-subgrade defect detection device based on vehicle-mounted ground penetrating radar. Background Technology

[0002] Currently, ground-penetrating radar (GPR) is used for detecting defects beneath highway surfaces. Various defects underground, such as cavities, pose significant safety hazards to vehicles. Similarly, defects of varying degrees may develop beneath the ballast bed of railway tracks over time, and the safety risks posed by these defects are unacceptable and must be detected and addressed promptly to prevent further losses. GPR, which uses electromagnetic waves to detect underground structures, is well-suited to address these hazards. However, manual operation during GPR detection is inefficient. Designing a vehicle-mounted GPR-based railway ballast bed-subgrade defect detection device could significantly improve work efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a railway ballast track-subgrade defect detection device based on vehicle-mounted ground-penetrating radar. This device is mainly used to traction vehicles traveling between tracks with a power source, to solve the hidden dangers to train operation safety caused by railway ballast track-subgrade defects, and to improve detection efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a railway ballast track-subgrade defect detection device based on vehicle-mounted ground penetrating radar, including a wheel, a wheel axle, a bearing seat, a foldable guide crossbar, a ground penetrating radar antenna mounting device and a connecting device. The wheel is engaged with the wheel axle, the wheel axle is supported by two bearing seats, and one side of the wheel is connected to an encoder through a coupling. A longitudinal beam of the device is fixedly connected to one side of the bearing seat, and one side of the foldable guide crossbar is supported by the longitudinal beam of the device.

[0005] The ground-penetrating radar antenna mounting device is mounted on the foldable guide crossbar using a pin shaft. A support rod is fixedly connected to one side of the mounting device, and a rear crossbeam of the equipment is fixedly connected to the bottom of the support rod. The ground-penetrating radar antenna mounting device is connected to the foldable guide crossbar through mounting ears on both sides. The mounting device has pin holes for easy attachment to a power tractor.

[0006] Preferably, the ground-penetrating radar antenna mounting device is slidably mounted on the foldable guide crossbar, which allows the trolley to adjust the detection position as needed when detecting the overall track bed.

[0007] Preferably, hinges are fixedly installed at both ends of the foldable guide crossbar, and extension rods are connected to the foldable guide crossbar through the hinges. The fully unfolded width is approximately the same as the width of the upper surface of the sleeper, which can ensure that the test surface covers the entire surface of the track bed when the ground penetrating radar antenna mounting device is replaced. During transportation, the extension rods at both ends can be folded, which greatly reduces the lateral dimension of the trolley.

[0008] Preferably, the ground-penetrating radar antenna mounting device includes four mounting studs, and springs are sleeved on the outside of the four studs. The springs abut against the bottom of the upper mounting rod and play a vibration damping role when the equipment is working.

[0009] Preferably, each of the four studs has a boss at its bottom, and the top of the boss has a threaded hole. The four studs are threaded into the corresponding threaded holes. The bottom end of the spring abuts against the upper surface of the boss, the top end of the spring abuts against the lower surface of the mounting rod, and the bottom end of the spring abuts against the upper surface of the boss. This facilitates vibration reduction for the ground-penetrating radar antenna mounting device during vehicle operation. Rubber pads are installed below the mounting positions on both sides of the mounting ears, which can also play a certain role in vibration reduction.

[0010] Preferably, a rib is fixedly connected between the connecting device and the support rod to prevent the connecting parts from being damaged.

[0011] The beneficial effects of this utility model are as follows:

[0012] By setting the above-mentioned structure, this utility model can promptly detect and resolve roadbed defects, avoiding significant safety hazards and substantial losses. At the same time, it solves the problem of low efficiency in manual pushing, improving the working efficiency of roadbed defect detection equipment and making it more practical.

Hinges 5 are fixedly installed at both ends of the foldable guide crossbar 4. The foldable guide crossbar 4 is connected to an extension rod 6 through the hinges 5. The fully unfolded width is approximately the same as the width of the upper surface of the sleeper, which ensures that the test surface covers the entire upper surface of the track bed when the ground-penetrating radar antenna mounting device 10 is replaced. During transportation, the extension rods 6 at both ends can be folded, greatly reducing the lateral size of the trolley. The connecting device 1 has a pin hole, and a rib plate 2 is fixedly connected between the connecting device 1 and the support rod 3 to prevent the connecting parts from being pulled apart.

The top of the boss 16 has a threaded hole. The four studs 17 are threaded into the corresponding threaded holes. The bottom of the spring 15 abuts against the upper surface of the boss 16, which facilitates a certain degree of vibration reduction for the ground-penetrating radar antenna mounting device 10 during vehicle operation. Rubber pads are installed below the mounting positions on both sides of the mounting ears 19, which can also play a certain role in vibration reduction.

[0021] When using this invention, the equipment needs to be moved onto the track to be tested, and the foldable guide bar 4 is opened.

After connecting the signal line, the trolley is driven to travel along the rail as the traction vehicle starts. During the test, the installation position of the ground-penetrating radar antenna mounting device 10 can be changed according to the required location.
