[0029] In some embodiments, a floor reference ruler is placed on the floor of the electric passenger train. When the first level 6 is level, the distance between the zero reference plane extension block 5 and the floor reference ruler is measured by a laser rangefinder 7 .

[0030] The following is combined with the appendix of this manual Figures 1 to 3 , the preferred implementation modes of the present disclosure are further elaborated in detail.

[0031] According to some embodiments, the first non-zero track homing device 1 and the second non-zero track homing device 2 have the same structure, such as Figure 2 As shown, the first non-zero track homing device 1 and the second non-zero track homing device 2 both include a non-zero track homing device body 8, a first magnet 9 and a second magnet 10. The first magnet 9 is arranged on the inner side of one end of the non-zero track homing device body 8, and the second magnet 10 is arranged on the inner side of the other end of the non-zero track homing device body 8.

[0032] Based on the above embodiments, Figures 1 to 3 As shown, in order to ensure that the first non-zero rail pecking device 1 and the second non-zero rail pecking device 2 are stably installed on the first side rail 3 and the second side rail 4, the first magnet 9 and the second magnet 10 are added to facilitate the first non-zero rail pecking device 1 and the second non-zero rail pecking device 2 to be stably attracted to the first side rail 3 and the second side rail 4.

[0033] According to some embodiments, Figures 2 to 3As shown, the first non-zero rail homing device 1 and the second non-zero rail homing device 2 both further include a first magnet mounting slot plug 11 and a second magnet mounting slot plug 12, the non-zero rail homing device body 8 is provided with a first cavity 13 and a second cavity 14, the first magnet 9 is arranged in the first cavity 13, the second magnet 10 is arranged in the second cavity 14, the first magnet mounting slot plug 11 closes the cavity opening connected to the first cavity 13, and the second magnet mounting slot plug 12 closes the cavity opening connected to the second cavity 14.

[0035] According to some embodiments, Figures 2 to 3 As shown, the first non-zero rail homing device 1 and the second non-zero rail homing device 2 also include a plurality of horizontal adjustment studs 15, an X-axis level 16 and a Y-axis level 17 are connected to the non-zero rail homing device body 8, the non-zero rail homing device body 8 is provided with a plurality of adjustment screw holes 23 corresponding to the number of the plurality of horizontal adjustment studs 15, the plurality of adjustment screw holes 23 are connected to the top and bottom of the non-zero rail homing device body 8, and the horizontal adjustment studs 15 are threadedly connected in the adjustment screw holes 23.

[0036] The principle based on the above embodiment is that by rotating the horizontal adjustment stud 15 on the first non-zero track homing device 1, the non-zero track homing device body 8 is raised, so that the X-axis level 16 and the Y-axis level 17 installed on the non-zero track homing device body 8 are activated. When the X-axis level 16 and the Y-axis level 17 are both horizontal, the reference plane on the first non-zero track homing device 1 is used as the zero track elevation plane.

[0037] By rotating the horizontal adjustment stud 15 on the second non-zero track homing device 2, the non-zero track homing device body 8 is raised, so that the X-axis level 16 and the Y-axis level 17 installed on the non-zero track homing device body 8 are activated. When the X-axis level 16 and the Y-axis level 17 are both horizontal, the reference plane on the second non-zero track homing device 2 serves as the zero track lifting plane.

[0038] Finally, the reference surface on the first non-zero rail homing device 1 and the reference surface on the second non-zero rail homing device 2 are adjusted to the same height plane, so that the first level 6 detects that the homing reference surface extension block 5 is in a horizontal state.

[0039] According to some embodiments, Figures 2 to 3 As shown, the first non-zero rail homing device 1 and the second non-zero rail homing device 2 both further include fixing nuts 18 corresponding to the number of the plurality of horizontal adjustment studs 15. Figure 3As shown, the bottoms of the plurality of adjusting screw holes 23 are all connected with nut fixing grooves 24 , the fixing nuts 18 are arranged in the nut fixing grooves 24 , and the horizontal adjusting studs 15 are threadedly connected with the adjusting screw holes 23 and the fixing nuts 18 in sequence.

[0040] According to some embodiments, the first non-zero rail coin finding device 1 and the second non-zero rail coin finding device 2 both further include a rail surface fitting alarm module 19, two micro switches 20, and a first cover plate 21. The non-zero rail coin finding device body 8 is provided with an alarm module slot and two switch slots, and the switch slots are arranged at both ends of the bottom of the non-zero rail coin finding device body 8. The two micro switches 20 are respectively inserted into the switch slots at both ends of the non-zero rail coin finding device body 8. The rail surface fitting alarm module 19 is placed in the alarm module slot, and the first cover plate 21 closes the slot connected to the alarm module slot.

[0042] Based on the working principle of the above embodiment, when the non-zero rail homing device body 8 is in contact with the rail surface 5, both micro switches 2 are pressed and closed, and the rail surface contact alarm module 19 receives the signal of the micro switch 2 being closed, and no alarm is issued. When one end of the non-zero rail homing device body 8 is tilted, a micro switch 20 will change from a closed state to an open state. That is, when one end of the first non-zero rail homing device 1 or the second non-zero rail homing device 2 is separated from the rail surface, a micro switch 20 will change from a closed state to an open state, and then the rail surface contact alarm module 19 receives the signal of the micro switch 2 being disconnected, and the rail surface contact alarm module 19 will issue an alarm sound and a light prompt to remind the operator that the corresponding non-zero rail homing device is in a non-horizontal state and needs to be readjusted.

[0043] In actual use, the present application can measure target data of subway trains on non-zero tracks, and can realize the measurement of multiple data types with a set of tools. Compared with the original measurement tools, it can adapt to more severe measurement environments, save a lot of time and personnel requirements required for the measurement process, reduce the unreliability factors of different measurement personnel, and improve measurement accuracy. The tool also has the advantages of easy maintenance and portability.

[0044] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0045] Although the present disclosure has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present disclosure can be implemented in a variety of forms without departing from the spirit or essence of the present application, it should be understood that the above-mentioned embodiments are not limited to any of the foregoing details, but should be widely interpreted within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
