[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0045] Please refer to Figures 1(a)-(b), Figure 1(a) is a schematic diagram of the use state of the rail profile detector 1 in the prior art when it is located on the rail 2; Figure 1(b) is a partial schematic diagram of Figure 1(a).
[0046] The rail profile detector 1 includes a connecting rod 11 and two left and right mobile detection devices 12. A running wheel 13 is provided below the mobile detection device 12, and a supporting wheel 15 is provided at the front and rear through a triangular bracket. The running wheel 13 and the supporting wheel 15 enable the detector to move stably on the rail 2. The left and right mobile detection devices 12 simultaneously collect the profile data of the left and right rails 2 through the built-in detection equipment. Usually, non-contact detection equipment such as lasers and cameras are used to realize uninterrupted data collection when the detector moves.
[0047] The rail profile detector 1 needs to be tested and calibrated regularly for its detection accuracy before leaving the factory and during subsequent maintenance. Usually, it is placed on the standard rail 300 and its working state is simulated. The relevant data of the standard rail 300 is collected for testing and calibration.
[0048] See also Figure 2-3 , Figure 2 This is a schematic diagram of the structure of an embodiment of the present application; Figure 3 for Figure 2 Schematic diagram of part of the structure.
[0049] The embodiment of the present application provides a testing device for a rail profile detector 1 , comprising a crossbeam 100 and two longitudinal beams 200 symmetrically arranged at both ends of the crossbeam 100 .

The standard rail 300 is used for collecting data for the rail profile detector 1 to be tested. Therefore, the length of the standard rail 300 only needs to meet the data collection range of the rail profile detector 1.
[0052] The wheel limit assembly 400 has a support surface 431 and a limit surface 432 . The support surface 431 is used to support the rail profile detector 1 . The limit surface 432 is located below the support surface 431 and is used to fix the wheel 15 of the rail profile detector 1 .

[0054] The mounting position of the standard rail 300, the roller 510, and the support surface 431 are located on the same straight line.
[0055] This method is to support and fix the rail profile detector 1 through the wheel limit assembly 400, and to achieve relative movement of the rail profile detector 1 through the roller 510 of the running auxiliary assembly 500, so as to control the overall length of the test device while achieving the movement of the rail profile detector 1 to simulate its working state, thereby reducing the occupied area. In addition, this test device provides a standard rail 300 for the rail profile detector 1 to collect data, realizes the simulation of the test environment of the rail profile detector 1, and cooperates with the wheel limit assembly 400 and the running auxiliary assembly 500 to make the length of the standard rail 300 shorter, thereby controlling the manufacturing cost and reducing the maintenance cost.
[0056] In one embodiment, the crossbeam 100 is connected to the middle of the longitudinal beam 200, and the standard rail 300 is installed in the middle of the longitudinal beam 200, so that the longitudinal beam 200, the standard rail 300 and the wheel limit assembly 400 are symmetrical about the crossbeam 100 in the horizontal and vertical directions, thereby improving the structural stability of the measuring device and the support stability of the rail profile detector 1, thereby improving the test accuracy.
[0057] In one embodiment, reinforcing plates are provided above the crossbeam 100 and below the longitudinal beam 200, that is, a crossbeam reinforcing plate 120 is provided above the crossbeam 100, and a longitudinal beam reinforcing plate 220 is provided below the longitudinal beam 200. The crossbeam 100 and the longitudinal beam 200 are staggered with reinforcing plates, which improves the strength of the measuring device, thereby further improving the test accuracy.
[0058] In one embodiment, adjustable feet 210 are provided at both ends of the longitudinal beam 200 to achieve horizontal adjustment of the test device, thereby improving the test accuracy.
[0059] In one embodiment, a power supply module 110 is disposed on the crossbeam 100 , and the power supply module 110 is used to supply power to the driving member 520 and / or the rail profile detector 1 for user convenience.
[0060] In one embodiment, the wheel limiting assembly 400 includes a bracket 410, and the bracket 410 is provided with a slide rail 420 along the length direction of the longitudinal beam 200, and a slider 430 is slidably provided on the slide rail 420, and a U-shaped groove is provided on the side of the slider 430 facing the cross beam 100, and the top surface of the slider 430 is a supporting surface 431, and the groove wall of the U-shaped groove of the slider 430 is a limiting surface 432, that is, the support and fixed position of the rail profile detector 1 are adjusted by the slider 430, so that it can adapt to a variety of rail profile detectors 1 of different specifications, and ensure that the data acquisition position of the rail profile detector 1 is aligned with the standard rail 300 to achieve data acquisition, thereby improving the versatility of the test device.
[0061] It can be understood that in order to improve the stability of the slider 430 in supporting and fixing the rail profile detector 1 , the slider 430 can be locked relative to the slide rail 420 .
[0062] In one embodiment, a scale 421 is provided on the side of the bracket 410 away from the beam 100 , and the extension direction of the scale 421 is the same as the extension direction of the slide rail 420 , thereby improving the movement accuracy of the slider 430 and facilitating user operation.
[0063] In one embodiment, the travel auxiliary assembly 500 further includes a mounting seat 530 and a driving member 520, such as a motor, disposed on one side of the mounting seat 530, preferably a motor with adjustable speed. The mounting seat 530 is disposed on the bracket 410, and the roller 510 is rotatably disposed in the mounting seat 530 and is in transmission connection with the driving member 520 to realize the rotation of the roller 510, and by arranging the roller 510 in the mounting seat 530, the stability of the roller 510 is improved, thereby improving the stability of driving the rail profile detector 1 to move relative to each other, and improving the test accuracy.
[0064] In one embodiment, the running auxiliary component 500 is provided with one, and is used to correspond to the running wheel 13 connected to the encoder 14 of the rail profile detector 1, so that the cost can be controlled while realizing the relative movement of the rail profile detector 1, and the moving path encoding can be realized, thereby improving the simulation degree of the working environment of the rail profile detector 1, thereby improving the test accuracy.
[0065] In one embodiment, the test device further includes an extension piece 310, which is L-shaped and is used to be detachably connected to the end face of the standard rail 300 through one end thereof, so as to provide standards for testing a variety of different equipment, such as a rail profile detector 1 having a rail corrugation data collection and analysis function, thereby improving the versatility of the test device. Preferably, the extension piece 310 is made of steel.
[0066] It should be noted that rail corrugation, also known as rail wave wear, refers to the wear phenomenon of the regular longitudinal ups and downs of the top surface of the rail. In this method, the extension piece 310 is used to provide a longer test surface for the rail profile detector 1, thereby controlling the required length of the standard rail 300, thereby improving versatility and controlling costs at the same time.
[0067] In one embodiment, the testing device further includes a height adjusting member 320, and the standard rail 300 is installed on the standard rail 300 installation position through the height adjusting member 320, so that the standard rail 300 is located within the data collection range of the rail profile detector 1, thereby being adaptable to a variety of rail profile detectors 1 of different specifications, and ensuring that the rail profile detector 1 is aligned with the standard rail 300 to realize data collection, thereby improving the versatility of the testing device.
