Description

Technical Field

[0001] This invention relates to the field of maintenance equipment technology, specifically to an auxiliary device for repairing track defects. Background Technology

[0002] Rail transit is a public transportation system that runs on fixed tracks, typically consisting of vehicles such as trains or trams. It includes various forms such as subways, light rail, and trams, providing fast, efficient, and safe urban transportation services by running on predetermined tracks. Rail transit features segmented operation, large transport capacity, low energy consumption, and environmental friendliness. It can effectively alleviate urban traffic congestion and provide a convenient and fast mode of travel. Tracks are the infrastructure of the rail transit system; regular inspection and maintenance of tracks ensure their safety. Damaged tracks may lead to train derailments or other accidents, threatening the safety of passengers and staff. The smoothness and geometry of the tracks have a significant impact on the operating efficiency of trains. Regular inspection and maintenance ensure that the smoothness and geometry of the tracks meet standards, reducing train swaying and energy consumption, and improving operating efficiency.

[0003] In the field of rail transit, track damage is mainly manifested as wear, corrosion, and track cracks caused by uneven stress. Most track maintenance in the current technology is carried out by manual hand inspection and maintenance, resulting in low maintenance efficiency. Summary of the Invention

[0023] according to Figure 4 and Figure 7 As shown, a track defect repair auxiliary device also includes a cleaning section. The cleaning section includes a fixing plate 32, which is fixed to the lower part of the inner wall of the frame 1. A plate 33 is provided on the side of the fixing plate 32 away from the frame 1. A side gear toothed plate 34 is provided on the side of the side gear toothed plate 34 away from the fixing plate 32. A meshing gear 35 is provided on the side of the side gear toothed plate 34 away from the plate 33. A support column 36 is inserted through the middle of the gear 35.

The top of the fixing post 38 is provided with two support posts 39 on both sides. The top of the support posts 39 is fixed to the bottom of the side wheel toothed plate 34. A cleaning brush 40 is provided on one side of the inner wall of the frame 1 corresponding to the fixing post 38. A connecting rod 41 is provided on both sides of the insert plate 33 away from the side wheel toothed plate 34. A fixing block 42 is provided at the outer end of the connecting rod 41. A spring 43 is provided at the end of the fixing block 42 away from the connecting rod 41. The inner side of the spring 43 is fixed to the side of the fixing plate 32.

[0024] Specific working principle: The extension and retraction motion between the drive cylinder 22 and the air rod 23 causes the air rod 23 to drive the U-shaped clamping block 24. The U-shaped clamping block 24 drives the drive arm 25 to slide in the strip groove 26. When the drive arm 25 slides left and right, it drives the fixed base plate 26 connected to the bottom, causing the sleeves 7 at both ends of the bottom of the fixed base plate 26 to slide on the guide rod 18, which drives the bidirectional gear plate 14 to move left and right. The bidirectional gear plate 14 drives the gear 16 to rotate. After the gear 16 rotates, it drives the side gear plate 15 that meshes with it on the other side, thereby driving the side clamping blocks 5 on both sides to move towards the center at the same time or to spread out to the sides at the same time. The side clamping blocks 5 will then drive the frame 1 to adjust the distance between them.

[0025] When the bidirectional gear plate 14 moves left and right, it drives the two meshing gears 37 on the outer side to rotate. After the gears 37 rotate, they drive the central support column 36, which in turn drives the gear 35 at the bottom. After the gear 35 rotates, it drives the side gear plate 34 that meshes on the side. The side gear plate 34 drives the insert plate 33 to slide in the groove on the side of the fixed plate 32. Under the elastic action of the spring 43, the side gear plate 34 limits the distance of its forward and backward sliding. The support column 39 drives the fixed column 38 to slide back and forth. The fixed column 38 drives the cleaning brush 40 to slide back and forth in the inner groove of the track. In this way, the inner groove of the track is cleaned. At the same time, as the moving wheel 3 drives the frame 1 forward, the limiting wheel 4 slides in the outer groove of the track, which provides a certain degree of stability and also plays a certain role in cleaning through sliding.

[0026] When the frame 1 moves forward driven by the moving wheels 3, the track is detected by the laser radar, high-definition camera and ultrasonic detector on the L-shaped frame 19. After a defect is detected in the track, the drive motor 1 57 or motor 2 54 is run. Motor 1 57 or motor 2 54 drives the inner arc frame 52 or the outer arc frame 53 to rotate. When the inner arc frame 52 swings left and right and the outer arc frame 53 swings back and forth, it will drive the support rod 3 50 to move, thereby driving the robotic arm 18 to rotate. The robotic arm 18 repairs the defects detected on the track.

[0027] There are three operating modes for motor 57 and motor 54. First, motor 57 operates while motor 54 does not. Motor 57 then drives the inner arc frame 52 to swing left and right. The inner arc frame 52 drives the support rod 50 to sway left and right along the groove of the outer arc frame 53. The inner end of the support rod 50 pulls the guide slider 49 to slide left and right within the transverse groove 59. Second, motor 54 operates while motor 57 does not. Motor 54 drives the outer arc frame 53 to swing back and forth. The support rod 50 slides back and forth within the groove of the inner arc frame 52. The guide slider 49 drives the adjusting ball 48 to swing back and forth, and the longitudinal groove 60 slides with the arc block 47. Third, motors 57 and 54 operate synchronously, causing the inner arc frame 52 and outer arc frame 53 to swing simultaneously in both left and right and back and forth directions. This allows for adjustment of multiple angles of rotation of the robotic arm 18, enabling effective maintenance of the track.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
