[0001] This utility model relates to the field of railway track technology, specifically a rapid cleaning and maintenance device for railway track bolts. Background Technology

[0002] Railway tracks are the routes used for trains, trams, and other vehicles. They are usually made of strip steel and are not only the foundation for the operation of transportation vehicles, but also a key part to ensure transportation safety and efficiency. They are the foundation of the modern transportation industry.

[0003] Railway tracks mainly consist of steel rails and track connecting devices. The track connecting devices are mainly used to fix the steel rails to the sleepers with bolts. Since the bolts are exposed for a long time during use, a large amount of rust may accumulate on the surface of the bolts after long-term use, which may affect the safety of bolt tightening. Therefore, the cleaning and maintenance of the bolts is crucial. The existing methods for cleaning railway bolts are mostly manual cleaning of the rust on the bolts, which is slow and inconvenient for large-scale and rapid cleaning and maintenance of railway track bolts.

[0027] Example 1:

[0028] like Figure 1 , Figure 3 and Figure 5 As shown, this utility model provides a rapid cleaning and maintenance device for railway track bolts, including a track 1 and a traveling car body 2. A control box 3 for controlling the entire operating system is provided on the upper front side of the traveling car body 2. A front housing 4 is fixed to the bottom front side of the traveling car body 2 by fastening bolts. A cleaning structure is provided inside the front housing 4. A rear housing 5 is fixed to the bottom rear side of the traveling car body 2 by fastening bolts. A maintenance structure is provided inside the rear housing 5.

[0029] The track 1 includes a bolster 11, which is located below the track 1. A pad 12 is provided on the bolster 11, and a rail clamp 13 is provided on the pad 12. A bolt 14 is threadedly connected to the track 1, and the track 1 is fixed to the bolster 11 by the rail clamp 13 and the bolt 14.

[0030] The traveling vehicle body 2 includes a lifting buckle 21. The traveling vehicle body 2 is fixed at the front and rear ends. A vertical support 22 is fixed on the inner side of the bottom of the traveling vehicle body 2. A drive motor 23 is fixed on the vertical support 22. A moving wheel 24 is fixed at the output end of the drive motor 23. The distance between the front and rear moving wheels 24 is the same as the distance between two adjacent bolts 14. The traveling vehicle body 2 can be lifted onto the track 1 by the lifting buckle 21 and an external crane. The moving wheel 24 can drive the traveling vehicle body 2 to move forward by the drive motor 23. During the alternating forward and stop of the traveling vehicle body 2, the surface of the bolts 14 can be derusted by the steel brush 411 and then the surface of the bolts can be sprayed with oil for maintenance by the oil spray pipe 53.

[0031] Furthermore, the cleaning structure includes a horizontal support 41, which is fixed inside the front housing 4. A cleaning motor 42 is fixed on the horizontal support 41, and a gear 43 is fixed to the output end of the cleaning motor 42. Two gears 43 mesh, and the output end of the cleaning motor 42 is fixedly connected to one of the gears 43. A bushing 44 is rotatably mounted on the inner bottom of the front housing 4, and a position sensor 45 and a camera 46 are respectively installed on the outer bottom of the front housing 4. A front electric rod 47 is fixed in the middle of the front housing 4, and a bearing bracket 48 is fixed at the bottom end of the front electric rod 47. The bearing bracket 48 is connected to the two sides by a shaft. A spline sleeve 49 is rotatable, and a spline shaft 410 slides axially above the spline sleeve 49. A steel brush 411 is fixed on the surface of the spline sleeve 49. When the traveling vehicle body 2 moves to the position of the bolt 14 to be derusted, the cleaning motor 42 can drive the spline shaft 410 and the spline sleeve 49 to rotate through the gear 43. In turn, the spline sleeve 49 can drive the steel brush 411 to rotate. At the same time, the front electric rod 47 can drive the axially sliding telescopic rod composed of the spline sleeve 49 and the spline shaft 410 to extend and move the two spline sleeves 49 downward to both sides of the bolt 14, so as to remove rust from the surface of the bolt 14.

[0032] Furthermore, the spline shaft 410 passes through the bushing 44 and is fixedly connected to the gear 43, so that the spline shaft 410 can be supported and rotated through the bushing 44.

[0033] Furthermore, the spline sleeve 49 and the spline shaft 410 form an axially sliding telescopic rod. When the front electric rod 47 extends or retracts, it can drive the spline sleeve 49 to move up and down through the bearing bracket 48, thereby enabling the axially sliding telescopic rod formed by the spline sleeve 49 and the spline shaft 410 to extend or retract. The bearing bracket 48 can also support the rotation of the spline sleeve 49, allowing the spline shaft 410 to drive the steel brush 411 to rotate through the spline sleeve 49.

[0034] Furthermore, two spline sleeves 49 are inserted into the strip-shaped rail clamp 13, and the two spline sleeves 49 are located on the front and rear sides of the bolt 14. When the spline sleeves 49 are moved to the front and rear sides of the bolt 14, the steel brush 411 can be rotated through the spline sleeves 49 to remove rust from the surface of the bolt 14.

[0035] Example 2:

[0036] like Figure 2 and Figure 4 As shown, based on Example 1, the safety and lifespan of bolt 14 can be further improved by setting up the maintenance structure.

[0037] Furthermore, the maintenance structure includes an oil reservoir 51, which is located on the upper rear side of the vehicle body 2. A rear electric rod 52 is fixed in the middle of the bottom surface of the rear engine box 5, and an oil injection pipe 53 is fixed at the bottom end of the rear electric rod 52. A position sensor 45 and a camera 46 are respectively installed on the outer side of the bottom surface of the rear engine box 5. When the oil injection pipe 53 is moved to the rust-removed bolt 14, the rear electric rod 52 is activated to drive the oil injection pipe 53 to move downward to the bolt 14, so that the surface of the bolt 14 can be sprayed with oil for maintenance treatment through the oil injection pipe 53.

[0038] Furthermore, an oil pump is installed inside the rear casing 5, and the oil pump is connected to the oil storage tank 51 and the oil spray pipe 53 through oil delivery pipes, so that the oil pump can deliver the rust removal oil inside the oil storage tank 51 to the oil spray pipe 53, and spray it onto the surface of the bolt 14 by the oil spray pipe 53.

[0039] Furthermore, the control box 3 is equipped with an image acquisition module and a controller. The image acquisition module is electrically connected to the camera 46 via wires. The controller is electrically connected to the drive motor 23, cleaning motor 42, position sensor 45, camera 46, front electric pole 47, rear electric pole 52, and oil pump located inside the rear housing 5 via wires. This allows the image acquisition module to analyze and process the image information captured by the camera 46. The controller can also control the drive motor 23, cleaning motor 42, position sensor 45, camera 46, front electric pole 47, rear electric pole 52, and oil pump located inside the rear housing 5 to work together, either individually or separately, to more quickly remove rust and maintain the surface of the bolt 14.

[0040] The working principle of this utility model is as follows: In use, the traveling vehicle body 2 can be hoisted onto the track 1 using the lifting buckle 21. Starting the drive motor 23 drives the moving wheels 24 to rotate, causing the traveling vehicle body 2 to move forward on the track 1. When the traveling vehicle body 2 moves to the bolt 14, the position sensor 45 detects the position of the bolt 14 and feeds the information back to the controller. The controller then controls the drive motor 23 to stop rotating and keeps the traveling vehicle body 2 stationary. At this time, the bolt 14 is located between the two spline sleeves 49. The appearance information of the bolt 14 is then observed by the camera 46 and transmitted to the image acquisition module for analysis. When the bolt 14 is free of rust, the front electric rod 47 remains stationary. When the camera 46 observes the bolt 14... After rust appears, the information is fed back to the controller, which starts the cleaning motor 42 and the front electric rod 47. The cleaning motor 42 drives one of the gears 43 to rotate, and through the meshing between the gears 43, the two spline shafts 410 can rotate synchronously in opposite directions. Then, the spline shafts 410 can drive the steel brush 411 to rotate through the spline sleeve 49. At the same time, the front electric rod 47 extends and drives the two spline sleeves 49 to move downward to the front and rear sides of the bolt 14 through the bearing bracket 48, so that the spline sleeves 49 are inserted into the strip-shaped rail clamp 13. Thus, the steel brush 411 can quickly scrape and remove rust from the surface of the bolt 14. After the rust removal is completed, the cleaning motor 42 stops rotating, the front electric rod 47 retracts and moves the spline sleeves 49 upward to reset.

[0041] After a bolt 14 is derusted, the vehicle body 2 continues to move forward. At this time, the spline sleeve 49 moves to the position of the previous bolt 14 that was not derusted. As mentioned above, the bolt 14 can continue to be derusted. After the position sensor 45 and camera 46 on the chassis 5 detect the derusted bolt 14, they transmit the information to the controller. The controller starts the oil pump and the rear electric rod 52 in the chassis 5. The rear electric rod 52 drives the oil spray pipe 53 downward to approach the bolt 14. The oil pump can spray the anti-rust oil in the oil tank 51 onto the surface of the bolt 14, so that the surface of the bolt 14 is protected from corrosion and forms a protective film to prevent moisture and oxygen from contacting the bolt, which can significantly slow down the rusting speed. In this way, after the previous bolt 14 is derusted, the vehicle body 2 moves and then stops, and the derusted bolt 14 can be sprayed with oil for maintenance.
