For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0027] Currently using Figure 3 and Figure 4 However, since it is a manual reading scale, the numerical reading results may vary from person to person, resulting in errors in the numerical values. Furthermore, the manual reading scale may also cause the preset values ​​to be inaccurate, and there is a risk that the adjusted sensing height does not meet the standard.

[0028] Therefore, the design concept of this application is to design an intelligent measurement tool that does not require manual reading of the scale and directly displays the value on the screen, thereby solving the problem of numerical errors caused by manual reading of the scale and inaccurate preset values ​​from the source.

[0029] like Figure 1-2 As shown, the present application provides an urban rail transit wheel sensor sensing height detection device, which is installed above the wheel sensor and includes a digital vertical scale, the digital vertical scale is connected to an adjustment mechanism, the adjustment mechanism is connected to a damping plate 7, and the damping plate 7 is connected to the digital vertical scale; a flat plate 9 is provided at the bottom of the digital vertical scale, a groove 10 is provided at the bottom of the flat plate 9, and the groove 10 is detachably plugged into the protrusion of the wheel sensor.

[0030] The digital vertical ruler includes a ruler rod 1 and a display 2 ; the top of the ruler rod 1 is connected to the adjustment mechanism, the bottom of the ruler rod 1 is connected to the flat plate 9 , and the display 2 is connected to the damping plate 7 .

[0031] You can directly purchase an existing digital vertical ruler, the price is about a hundred yuan, and the specific brand can be selected by the user according to his own situation.

[0032] Among them, the adjustment mechanism includes an upper connecting cap 3 connected to the top of the ruler rod 1, a nut 4 is connected to the back of the upper connecting cap 3, a threaded rod 5 is threadedly connected to the nut 4, and the bottom of the threaded rod 5 is rotatably connected to the damping plate 7; wherein, the bottom of the threaded rod 5 is connected to a bearing 6, the bearing 6 is embedded in the center of the damping plate 7, and the bearing 6 is installed in the middle position of the damping plate 7 as much as possible. The bearing 6 is set to support the rotation of the threaded rod 5 to prevent the damping plate 7 from rotating with the threaded rod 5, and the damping plate 7 moves up and down with the rotation of the threaded rod 5; when in use, the threaded rod 5 is screwed to raise and lower the damping plate 7.

[0033] The bottom of the ruler rod 1 is connected with a lower connecting cap 8, and the lower connecting cap 8 is connected to a flat plate 9; the lower connecting cap 8 and the flat plate 9 can be welded.

[0034] The damping plate 7 is provided with a connection port 11 , the display 2 is provided in the connection port 11 , the display 2 is threadedly connected to an L-shaped plate 12 , and the L-shaped plate 12 is threadedly connected to the damping plate 7 .

[0035] The damping plate 7 is provided with a connection port 11, and then the display 2 is placed therein, and the back of the display 2 is threadedly connected to the damping plate 7 by an L-shaped plate 12; the design of the connection port 11 is as follows: Figure 1-2 As shown, it is more conducive to making room for the nut 4, the threaded rod 5, and the bearing 6 to be arranged in the middle of the damping plate 7, so that when the threaded rod 5 is screwed, the damping plate 7 can be stably raised and lowered.

[0036] When measuring with existing measurement tools, such as Figure 3-4 As shown, connect the wheel sensor to the tester, and use the measuring tool shown in the figure to place it directly above the wheel sensor (there is a protrusion on the upper surface of the wheel sensor. When the groove at the bottom of the measuring tool coincides with the protrusion, it can be ensured that it is directly above the wheel sensor). Rotate the knob (the existing measuring tool knob 200) to adjust the height of the damping plate (the existing measuring tool damping plate 100) up and down. When the LED lights of the testers SI and SII are on at the same time, read the scale value of the ruler (the existing measuring tool scale 300) to obtain the sensing height of the wheel sensor; if the read value exceeds the standard range, adjust the scale preset value to 43.5mm by turning the knob, and then adjust the internal coil height of the wheel sensor. When the LED lights of the testers SI and SII are on at the same time, stop adjusting the internal coil height. At this time, the sensing height of the wheel sensor has been adjusted to 43.5mm.

[0037] As mentioned above, the shortcomings of existing measuring tools are: 1. Through manual reading of the scale, the numerical reading results may vary from person to person, and there are inaccurate factors; 2. The numerical value may change after the preset value, and the accuracy of the set value cannot be ensured in real time, and there is a risk that the adjusted sensing height does not meet the standard.

[0038] When measuring this application, connect the wheel sensor to the tester, and place the detection device directly above the wheel sensor (there is a protrusion on the upper surface of the wheel sensor. When the groove at the bottom of the detection device coincides with the protrusion, it can be ensured that it is directly above the wheel sensor). Rotate the nut to adjust the height of the damping plate up and down. When the LED lights of the testers SI and SII are on at the same time, read the value displayed on the digital vertical scale, which is the sensing height of the wheel sensor; if the read value exceeds the standard range, adjust the preset value of the digital vertical scale to 43.5mm through the nut, and then adjust the height of the internal coil of the wheel sensor. When the LED lights of the testers SI and SII are on at the same time, stop adjusting the height of the internal coil. At this time, the sensing height of the wheel sensor has been adjusted to 43.5mm.

[0039] The present application combines a digital scale and a damping plate through an adjustment mechanism to form a new type of special tool. A flat plate is connected to the 0 scale line at the bottom of the digital scale, and a groove is opened on the flat plate. After placing the newly invented tool directly above the wheel sensor, the damping plate can be adjusted up and down by loosening the adjustment mechanism. The wheel sensor is connected to the tester, and the height of the damping plate is adjusted by loosening the adjustment mechanism. When the LED lights of the tester SI and SII are on at the same time, the value displayed on the readout scale is the sensing height of the wheel sensor. The principle of presetting the sensing height is similar to measuring the sensing height.

[0040] Although the present invention has been described in detail with reference to the accompanying drawings and in combination with preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, ordinary technicians in the field can make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions should all be within the scope of the present invention. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present invention, which should all be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
