[0025] Please see Figure 1-5This utility model provides a technical solution: a railway mobile measuring device, including a track trolley 1. A first infrared ranging sensor 7 is installed at the bottom of the track trolley 1, and a height measuring mechanism is installed at the bottom of the track trolley 1 for measuring the rail height in conjunction with the first infrared ranging sensor 7 under adverse weather conditions. The first infrared ranging sensor 7 has its output end pointing towards a box-shaped block 8. A second infrared ranging sensor 14 is installed on both sides of a first baffle 10 with its detection end pointing towards a first movable block 12. A third infrared ranging sensor 19 is installed on the side of a second baffle 13 away from the first movable block 12 with its detection end pointing towards a second movable block 17. The height measuring mechanism includes a piston cylinder 5, which is installed at the bottom of the track trolley 1. A connecting plate 6 is installed at the output end of the piston cylinder 5, and a box-shaped block 8 is installed at the bottom of the connecting plate 6. The box-shaped block 8 is hollow. Because the output end of the piston cylinder 5 is equipped with a connecting plate 6, which is fixed on the box block 8, when the equipment moves up and down, the first infrared ranging sensor 7 detects the distance between the box block 8 and the track trolley 1, records the data, and transmits it to the processor via an electrical signal for analysis of the height of the rail and the track trolley 1.
[0026] The height measuring mechanism includes a second infrared ranging sensor 14 and a track width measuring mechanism for measuring railway width in adverse weather conditions. The track width measuring mechanism includes a connecting rod 9, the outer wall of which is fixed to the inner wall of a box-shaped block 8.

A first movable block 12 is located at the end of the first spring 11 furthest from the first baffle 10. The outer wall of the first movable block 12 is slidably installed inside the connecting rod 9. A second baffle 13 is located on the side of the first movable block 12 furthest from the first spring 11. When the equipment moves on the track, the second baffle 13, located inside the guide rail, moves left and right when the track width changes, thus moving the first movable block 12. The detection end of the second infrared ranging sensor 14 on the first baffle 10 measures the distance between the first movable block 12 and the first baffle 10, and the recorded data is transmitted to the processor via an electrical signal for analysis of the width of the railway.
[0027] Both ends of the track width measuring mechanism are equipped with third infrared ranging sensors 19.

A second movable block 17 is located on the side of the second spring 16 away from the second baffle 13, with its outer wall slidably mounted to the inner wall of the mounting rod 15. A third baffle 18 is located on the side of the second movable block 17 away from the second spring 16. When the width of the track changes, the third baffle 18 moves left and right. The detection end of the third infrared ranging sensor 19 measures the distance between the second movable block 17 and the second baffle 13, records the data, and transmits it to the processor via an electrical signal for analysis of the track width.
[0028] The height measurement mechanism, track width measurement mechanism, and rail width measurement mechanism are all equipped with a planar detection mechanism for checking the flatness of the track under adverse weather conditions. The planar detection mechanism includes a first attitude sensor 20, which is located inside the box-shaped block 8. A second attitude sensor 2 is located on the side of the first movable block 12 near the first spring 11, and a third attitude sensor 4 is located on the side of the second movable block 17 near the second spring 16. When the equipment moves on the track, the first attitude sensor 20, second attitude sensor 2, and third attitude sensor 4 are used to detect the attitude at each position and to check the smoothness of the track.
[0029] A fourth infrared ranging sensor 3 is installed at the bottom of the box block 8. The fourth infrared ranging sensor 3 is used to measure the height from the ground to the box block 8.
