Embodiment 1
[0036] Such as figure 1 and figure 2 As shown, a wheel inner distance measuring device 100 includes a bracket 1, the bracket 1 includes a base plate 10, and the base plate 10 is provided with a laser sensor 2 and a camera 3, and the laser sensor 2 scans laser light to the inner side of the wheel, so The irradiation range of the camera 3 covers the scanning range of the laser sensor 2, and the data acquired by the laser sensor 2 and the camera 3 are uploaded to the controller for distance measurement.
[0037] Specifically, such as figure 1As shown, a wheel inner distance measurement device 100 is designed, including a bracket 1, and the bracket 1 includes a base plate 10, and the base plate 10 is provided with a laser sensor 2 and a camera 3, and the laser sensor 2 scans laser light to the inner side of the wheel, The irradiation range of the camera 3 covers the scanning range of the laser sensor 2, and the laser sensor 2 scans the inner side of the wheel, obtains correspon...
Embodiment 2
[0048] Such as image 3 As shown, a wheel inner distance measurement system includes several said wheel inner distance measuring devices 100, and several said wheel inner distance measuring devices 100 are placed at intervals between two parallel first rails 4 and second rails 5 In the middle, the top surface of the wheel inner distance measuring device 100 is lower than the rail; the first rail 4 is for the left wheel 6 to travel, and the second rail 5 is for the right wheel 7 to travel;
[0049] In a specific embodiment, several groups of wheel inner distance measuring devices 100 can be set in the middle of two parallel rails, and the wheel inner distance measuring devices 100 can be arranged at intervals, for example, four groups can be placed, and the same wheel can be scanned multiple times to obtain Multiple sets of data can improve the accuracy of measurement.
[0050] It also includes a third laser sensor 8 located on the outside of the left wheel 6 and a fourth lase...
Embodiment 3
[0056] Such as Figure 4 and Figure 5 As shown, a method for measuring the inner distance of a wheel, using the said inner distance measurement system, comprises the following steps:
[0057] Step 101: When the train wheels pass by, activate the wheel inner distance measurement system to work, replace the left wheel 6 and the right wheel 7 with two planar plates 14 connected together by connecting rods 13, the connection The length of the rod 13 is L, and the thickness of the planar plate 14 is T;
[0058] Step 102: The first laser sensor 20 and the third laser sensor 8 scan the two planes inside and outside of the flat panel 14 respectively; the second laser sensor 21 and the fourth laser sensor 9 scan respectively The inner and outer two planes of the other said plane plate 14;
[0059] Step 103: Acquiring the data of the first laser sensor 20, the second laser sensor 21, the third laser sensor 8 and the fourth laser sensor 9 and calibrating them into a unified coordinat...
