The connecting block 11 is fixedly connected to the front end of the fixing frame 2, and the control panel 12 is fixedly connected to the front end of the connecting block 11. The inner walls of the two brackets 7 are rotatably connected with limit wheels 9, and the tops of the inner walls of the opposite sides of the two slide bars 3 are fixedly connected with springs 10. The two springs 10 are fixedly connected to the left and right sides of the top of the fixing frame 2, and the front end of the base 1 is fixedly connected with a fixing bar 18, and the top of the fixing bar 18 is fixedly connected with an electronic straight ruler 19.

[0033] The two rollers 20 on the left and right sides are brought into contact with the two sides of the track, and the base 1 is moved forward by the rolling of multiple rollers 20. The tracks on both sides are measured by the electronic straight ruler 19 on the fixed bar 18. The control panel 12 is electrically connected to the motor 4 and the bolt gun 8. When adjustment is needed, one of the motors 4 is controlled by the control panel 12 to rotate the gear 6. When the gear 6 rotates, the meshing drives the rack 5 to make the slide bar 3 slide downward on the side of the fixed frame 2, and at the same time drives the bracket 7 to slide downward and align the two bolt guns 8 with the two sides of one of the tracks. The nuts fixed on both sides of the track are removed and then taken out or filled with fillers to achieve leveling of the tracks on both sides. After adjustment, the two bolt guns 8 are tightened with the nuts on both sides for installation, and the bracket 7 is prevented from sliding down excessively by the limit wheel 9. After completion, the motor 4 stops rotating the gear 6. At this time, the spring 10 drives the slide bar 3 to slide upward by rebounding, the bolt gun 8 leaves the nut, and the base 1 measures forward again.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The front end of the bottom of the base 1 is slidably connected with a left and right opposite slider 22, the rear side of the bottom of the base 1 is slidably connected with a left and right opposite slider 1, the bottoms of the two sliders 22 are rotatably connected with a connecting bar 24, the bottoms of the two sliders 21 are rotatably connected with a connecting bar 1 23, the two connecting bars 1 23 are rotatably connected to the opposite sides of the two connecting bars 24, a brake rod 28 is fixedly connected between the bottoms of the two connecting bars 1 23, a brake rod 1 27 is fixedly connected between the bottoms of the two connecting bars 1 23, a cylinder 26 is fixedly connected to the bottom of the base 1, a fixed block 25 is fixedly connected between the two sliders 22, and the output end of the cylinder 26 is fixedly connected to the rear side of the fixed block 25.

[0035] When the tracks on both sides need to be leveled, the cylinder 26 is started to drive the fixed block 25 to drive the two sliders 22 to slide backward at the bottom of the base 1. When the two sliders 22 slide forward, they will drive the two connecting bars 1 23 to rotate through the two connecting bars 24. When the two connecting bars 1 23 rotate, they will drive the slider 1 21 to slide forward at the bottom of the base 1. The connecting bars 1 23 and the connecting bars 2 24 rotate in opposite directions respectively and open to press the brake bars 1 27 and the brake bars 2 28 against the ground between the tracks on both sides, so that the base 1 stops moving forward, which is convenient for leveling the tracks.

[0036] Reference Figure 1 and Figure 2 A baffle 13 is fixedly connected to the top front end of the base 1, a connecting block 11 passes through the baffle 13, a control panel 12 is arranged at the front end of the baffle 13, a sun visor 14 is fixedly connected to the top of the base 1, a fixing block 16 is fixedly connected to the bottom front end of the baffle 13, and a storage drawer 17 is interactively connected to the left and right sides of the fixing block 16, the fixing block 16 is arranged at the bottom of the control panel 12, and an observation window 15 is arranged at the top front end of the baffle 13.

[0037] The two handles at the front end of the baffle 13 are held to push the base 1 forward on the track. The baffle 13 can block the wind in front and the road conditions in front can be observed through the observation window 15. The sun visor 14 blocks the sunlight on the top. The drawers 17 on both sides are pulled out to store the personal belongings of the staff, and then the two drawers 17 are slid and pushed into the fixed block 16.

[0038] Working principle: When the leveling device for railway track measurement is used, the base 1 is placed on the track, and the two rollers 20 on both sides are respectively against the left and right sides of the track, and the handle at the front end of the baffle 13 is held and pushed forward. The tracks on both sides are observed through the electronic straight ruler 19. When leveling is required, the start cylinder 26 is retracted and drives the fixed block 25 backward, and at the same time drives the two sliders 22 to slide backward. At this time, the two connecting strips 24 will drive the two connecting strips 1 23 to rotate in opposite directions and open. When the two connecting strips 1 23 rotate, they will drive the two sliders 1 21 to slide forward. The two connecting strips 1 23 and the two connecting strips 24 rotate in opposite directions and open. After the two connecting strips 1 23 and the two connecting strips 24 rotate in opposite directions and open, they will be pressed against the ground between the tracks on both sides through the brake rod 1 27 and the brake rod 2 28 to stop the forward movement of the base 1, and one of the motors 4 is controlled by the control panel 12. The gear 6 is driven to rotate. When the gear 6 rotates, the meshing rack 5 drives the slide bar 3 to slide down. At this time, the bracket 7 will also drive the two bolt guns 8 to descend together. The two bolt guns 8 are respectively engaged with the nuts on the left and right sides of one of the tracks and screwed to disassemble. The filler is taken out or added to make it level with the track on the other side. After the adjustment is completed, the nuts are tightened and installed again through the two bolt guns 8, and the slide bar 3 is slid upward as a whole through the spring 10. The start cylinder 26 is extended to make the fixed block 25 drive the two sliders 22 to slide forward. At the same time, the two connecting strips 1 23 and the two connecting strips 24 will rotate in opposite directions and fold and retract to make the brake rod 28 and the brake rod 1 27 leave the ground between the two tracks, and the two sliders 1 21 will slide backward. At this time, the two handles in front of the baffle 13 can be held and pushed forward to continue measuring.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
