Detailed Implementation
[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0026] Example 1
[0027] like Figures 1-7 As shown, a railway track maintenance and inspection device includes: a vehicle body 1, with two pairs of universal wheels 11 fixedly installed at the bottom of the vehicle body 1, mounting plates 12 respectively on opposite sides of the vehicle body 1, two rollers 13 fixedly connected to the bottom of the two mounting plates 12, frames 14 fixedly installed near the middle of the bottom of the two mounting plates 12, ultrasonic flaw detectors 15 fixedly installed at the top of the frames 14, and an electrical control cabinet 16 fixedly connected to the top of the vehicle body 1; a storage component, which is located inside the mounting plates 12 for storing the two mounting plates 12; and a marking component, which is located on the two frames 14 for marking damaged areas on the rail.
[0028] When maintaining the rails, the vehicle body 1 is moved using the handles on the body and the casters 11 at the bottom. The body 1 is moved to a surface level with the two rails, and then positioned between them. During this movement, the rollers 13 do not touch the ground. The casters 11 are rubber wheels, and the rollers 13 are metal wheels. Then, the two mounting plates 12 are unfolded using the storage assembly, aligning the frame 14 at the bottom of the mounting plates 12 with the rails. The vehicle body 1 is then pushed forward, moving it away from the surface level with the rails, causing the two rollers 13 on both sides to fall onto the rails. Meanwhile, the frames 14 on both sides are fitted onto the rails, so that the casters 11 are suspended in the air and the car body 1 is supported by the rollers 13. After the inspection is completed, the car body 1 moves to the inspection station and is level with the two rails. The rollers 13 are separated from the rails and the casters 11 support the car body 1. Then the control mounting plate 12 is retracted, and the electronic equipment is turned on through the electrical control cabinet 16 to push the car body 1 to move. The ultrasonic flaw detector 15 can inspect the surface of the rails. When damage is detected on the rails, the damaged area is marked by the marking component so that maintenance personnel can replace the damaged rails.
[0029] Example 2
[0030] Based on Embodiment 1, the storage assembly includes: a storage slot 2, a guide slot 21, a bidirectional threaded rod 22, a moving block 23, a scissor-type folding frame 24, and a connecting block 25. Two storage slots 2 are formed on one side of the mounting plate 12. Guide slots 21 are respectively formed at the bottom near the center of each of the two storage slots 2. A bidirectional threaded rod 22 is rotatably connected between the inner walls of the two guide slots 21 at opposite ends. Moving blocks 23 are threadedly connected to the two ends of the threads of the two bidirectional threaded rods 22. Moving blocks 23 are slidably connected to the guide slots 21. Scissor-type folding frames 24 are provided inside each of the two storage slots 2. Two rotating rods in the middle of the two scissor-type folding frames 24 are respectively connected to the two moving blocks 23. Two connecting blocks 25 are fixedly connected to opposite sides of the two mounting plates 12. Connecting block 25, two scissor folding frames 24 are rotatably connected to two opposite connecting blocks 25 at opposite ends, a partition plate 26 is fixedly connected between two storage slots 2, gear a27 is rotatably connected between opposite sides inside the partition plate 26, a waterproof shell 28 is fixedly installed at the top of the vehicle body 1 near the middle, a shield 29 is fixedly connected to one side of the waterproof shell 28, the interior of the shield 29 is connected to the interior of the partition plate 26, the rotating shafts at opposite ends of gear a27 are respectively connected to opposite ends of two bidirectional threaded screws 22, a motor 210 is fixedly installed inside the waterproof shell 28, one end of the drive shaft of the motor 210 extends into the interior of the waterproof shell 28 and is fixedly connected to gear b211, a transmission chain 212 is connected between gear a27 and gear b211.
[0031] After the rail inspection is completed, the motor 210 is started via the control panel inside the electrical control cabinet 16. The motor 210 drives gear b211 to rotate, which in turn drives gear a27 via the transmission chain 212. The waterproof shell 28 serves to prevent water leakage, and the shield 29 protects the transmission chain 212 and gear b211 from being caught in debris. Gear a27 drives two double-ended threaded screws 22 to rotate. When the two double-ended threaded screws 22 rotate, they engage with two external moving blocks 23. Since the moving blocks 23 are located inside the guide groove 21, they are guided... The limiting moving block 23 of the groove 21 can only move horizontally, thereby controlling the two moving blocks 23 to move in opposite directions, causing the intersection of the scissor folding frame 24 to separate to both sides, so that the scissor folding frame 24 retracts and drives the two mounting plates 12 to move towards the vehicle body 1, thereby retracting the two mounting plates 12, reducing space occupation and facilitating storage. Conversely, when the motor 210 is controlled to rotate in the opposite direction, the intersection of the two scissor folding frames 24 is brought closer to the center according to the opposite principle, so that the two scissor folding frames 24 unfold and push the two mounting plates 12 to move to both sides.
[0032] Among them, three pairs of fixed cylinders 4 are fixedly installed on the top of the vehicle body 1. Each fixed cylinder 4 has a telescopic rod 41 slidably connected inside. One end of the three telescopic rods 41 located on the same side is connected to the top of the mounting plate 12.
[0033] When the mounting plate 12 moves, it will cause the telescopic rod 41 to be pushed out or retracted from the fixed cylinder 4, thereby strengthening the support between the two mounting plates 12 and the vehicle body 1.
[0034] Example 3
[0035] Based on Embodiment 1, the marking assembly includes: a water storage plate 3, a nozzle 31, a baffle 32, a solenoid valve 33, a storage tank 34, and a booster pump 35. Two water storage plates 3 are fixedly installed on the top of the two frames 14 respectively, and multiple nozzles 31 are fixedly installed on the bottom of each water storage plate 3. An ultrasonic flaw detector 15 is located between the two water storage plates 3, and a baffle 32 is provided between the two water storage plates 3 and the ultrasonic flaw detector 15. The top of the baffle 32 is detachably connected to the top of the frame 14 by screws. Solenoid valves 33 are fixedly installed on the top of the two mounting plates 12 near the frame 14 respectively. A storage tank 34 is fixedly installed on the top of the vehicle body 1, and a booster pump 35 is fixedly installed on the top of the storage tank 34. The output ends of the two solenoid valves 33 are connected to the two water storage plates 3 through pipes respectively. The output end of the booster pump 35 is connected to the inside of the storage tank 34. Two feed pipes 36 are fixedly connected to one side of the storage tank 34, and the two feed pipes 36 are respectively connected to the input ends of the two solenoid valves 33.
[0036] Before inspecting the rails, colored paint is poured into the storage tank 34, and then the booster pump 35 is turned on. After the booster pump 35 is turned on, it pressurizes the storage tank 34. When the pressure inside the storage tank 34 reaches a certain level, the booster pump 35 stops working. When the pressure inside the storage tank 34 drops below a certain level, the booster pump 35 starts working again to pressurize the storage tank 34. Under pressure, the colored paint flows into the two supply pipes 36. When the ultrasonic flaw detector 15 detects damage on the rails, the corresponding solenoid valve 33 is activated, and the colored paint enters the two water storage plates 3 and is then sprayed out from the nozzle 31. The baffle 32 has a groove that matches the rails, so that the baffle 32 matches the rails. The two baffles 32 can prevent the colored paint from being sprayed onto the ultrasonic flaw detector 15, thereby marking the damaged area so that maintenance personnel can quickly identify the damaged rails, which is beneficial for further evaluation and replacement of the damaged rails.
