Technical Field

[0001] This utility model relates to the field of railway construction technology, specifically a railway track settlement detection tool. Background Technology

[0002] Track settlement refers to the irregular subsidence of the ground foundation where the tracks are laid, caused by the ground's inability to withstand the load-bearing demands of transportation. This phenomenon is particularly pronounced in underground tunnel areas with soft foundations and abundant water resources. Track settlement can lead to localized stress concentration on the tracks, accelerating track damage and causing rapid aging, posing a significant safety hazard to train operation.

[0003] Currently, the inspection of railway track settlement is generally carried out by staff visually judging the distance the rails float up and down when vehicles pass by, or by using an infrared rangefinder. However, the accuracy of visual judgment by staff is low. Therefore, we propose a railway track settlement detection tool. Utility Model Content

[0023] A fourth slide groove 10 is provided inside the support rod 2 and on one side of the third slide groove 9. A fourth slide groove 12 is fixedly connected to one side of the third slide groove 11, and the fourth slide groove 12 is slidably connected inside the fourth slide groove 10.

[0024] The fourth slide groove 10 is provided with multiple telescopic springs 13. One end of the telescopic spring 13 is fixedly connected to the inner wall of the fourth slide groove 10, and the other end of the telescopic spring 13 is fixedly connected to one side of the fourth slider 12.

[0025] The support rod 2 has a fifth sliding groove 16 inside, and a fifth slider 19 is slidably connected inside the fifth sliding groove 16. A threaded rod 17 is rotatably connected inside the fifth sliding groove 16. The threaded rod 17 is rotatably connected inside the fifth sliding groove 16 through a bearing. Through the cooperation of the threaded rod 17 and the fifth slider 19, the two push rods 20 can be driven to slide inside 18, thereby pushing the fourth slider 12 to move, and then driving the third slider 11 to move into the third sliding groove 9, thereby releasing the limit on the second slider 7, thus facilitating the reset of the connecting rod 14 and the contact plate 15.

[0026] Inside the support rod 2 and outside the fifth slide groove 16, there are two corresponding 18s. Two corresponding push rods 20 are fixedly connected to the outside of the fifth slider 19. The push rods 20 are slidably connected inside the 18. The two ends of the fourth slider 12 extend into the interior of the two 18s respectively. The fourth slider 12 and the two push rods 20 cooperate with each other.

[0027] The base plate 1 has a rotating groove 21 inside, and a rotating shaft 22 is rotatably connected inside the rotating groove 21. A support rod 23 is fixedly connected to the outside of the rotating shaft 22 and inside the rotating groove 21. The rotating shaft 22 is rotatably connected to the inside of the rotating groove 21 through a bearing. Through the cooperation of the support rod 23 and the rotating shaft 22, the connecting rod 14 and the contact plate 15 can be lifted up, thereby facilitating the reset of the connecting rod 14 and the contact plate 15.

[0028] The base plate 1 has a transmission groove 24 inside, and a first transmission shaft 25 is rotatably connected inside the transmission groove 24. A worm gear 26 is fixedly connected to the outside of the first transmission shaft 25 and inside the transmission groove 24. A second transmission shaft 27 is rotatably connected inside the transmission groove 24. A worm 28 is fixedly connected to the outside of the second transmission shaft 27 and inside the transmission groove 24. The worm 28 meshes with the worm gear 26. Both the first transmission shaft 25 and the second transmission shaft 27 are rotatably connected to the inside of the transmission groove 24 through bearings. One end of the first transmission shaft 25 extends into the inside of the rotating groove 21 and is fixedly connected to the rotating shaft 22. Through the cooperation of the first transmission shaft 25, the worm gear 26, the second transmission shaft 27 and the worm 28, the rotating shaft 22 and the support rod 23 can be driven to rotate, thereby supporting and resetting the connecting rod 14 and the contact plate 15. A scale strip 3 is provided on the outside of the support rod 2.

[0029] In summary, when using this railway track settlement detection tool, the operator installs the base plate 1 between the lower part of the rail and the ballast using fixing nails, so that the contact plate 15 contacts the lower part of the rail. As the rail descends, it drives the contact plate 15 and the connecting rod 14 to descend as well. Then, the connecting rod 14 drives the two first sliders 6 and 7 to slide inside the first slide groove 4 and the second slide groove 5. As the first sliders 6 and 7 descend, they continuously push the third slider 11 and the fourth slider 12 into the third slide groove 9 and the fourth slide groove 10, causing the telescopic spring 13 to contract. When the rail rebounds, the telescopic spring 13, having lost its limit, pushes the fourth slider 12 and the third slider 11 back to their original positions, causing one end of the third slider 11 to insert into the limiting groove 8 and fix the second slider 7. This allows the operator to use the scale strip 3 on the outside of the support rod 2 in conjunction with the connecting rod 14... The position is determined by reading the rail settlement value. Corresponding magnets are provided on the outer side of the second slider 7 and the inner wall of the second slide groove 5. This prevents the connecting rod 14 and contact plate 15 from automatically descending when the rail has not descended. When resetting the connecting rod 14 and contact plate 15, rotating the knob drives the threaded rod 17 to slide the fifth slider 19 and the two push rods 20. This pushes multiple fourth sliders 12 and third sliders 11 to slide inside the third slide groove 9 and the fourth slide groove 10, pulling the third slider 11 out of the limiting groove 8, thereby releasing the limiting of the second slider 7. Then, by rotating the handle, the first drive shaft 25, worm gear 26, second drive shaft 27 and worm 28 are rotated, which in turn drives the rotating shaft 22 and rotating groove 21 to rotate, thereby lifting the connecting rod 14 and contact plate 15 and resetting them.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
