Description

Technical Field

[0001] This utility model belongs to the field of urban rail inspection technology, specifically relating to an urban rail corrugation fault detection device. Background Technology

[0002] Rail corrugation is a major type of rail damage. It is a periodic, wave-like irregularity that appears on the longitudinal surface of the rail. It has two properties: wavelength and peaks and valleys. In order to ensure the safe use of the rail, people often inspect the rail for corrugation. When inspecting the rail, people generally use corrugation detection equipment to test the thickness and flatness of the rail.

[0003] However, existing testing equipment generally only performs testing without marking uneven areas during the process. This means that when people are testing, they need to manually mark the areas, or repair any unevenness or problems found, and then test again. This kind of operation means that people must follow the testing organization during the repair process. If the testing equipment cannot proceed to the next area in time after the repair is completed, the repair process will be delayed, thus reducing the efficiency of equipment testing and repair. Utility Model Content

[0004] The purpose of this utility model is to provide a fault detection device for urban rail transit steel rail corrugation, in order to solve the problem mentioned in the background art. However, existing detection equipment can generally only perform detection without marking uneven areas at the same time. This leads to the need for manual marking during inspection, or direct repair when unevenness or problems are detected, followed by inspection again. Such operations require the repair personnel to follow the inspection mechanism synchronously. This results in delays in the repair process if the inspection equipment fails to proceed to the next inspection after the repair is completed, thereby reducing the efficiency of equipment inspection and repair.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes two U-shaped fixed seats, with the same U-shaped fixing frame hinged to the upper surface of the two fixed seats. A support frame is mounted on the upper surface of the fixing frame, and the support frame is arranged at an angle. A data analyzer is mounted at the top of the support frame, and a ring-shaped handle is mounted on the support frame. Two rotating shafts are installed inside the fixed seats, and two balance wheels are rotatably mounted on the rotating shafts. A data acquisition unit is mounted on the inner top surface of the fixed seats. Both data acquisition units are electrically connected to the data analyzer via connecting lines. The data acquisition units are located between the two rotating shafts on the same side. The same mounting plate is mounted on the upper surface of the two fixed seats, and the mounting plate is located behind the fixing frame. An electric push rod is mounted on the upper surface of the mounting plate, and the output shaft of the electric push rod extends through to the bottom of the mounting plate and is fitted with a marking sponge.

[0006] By adopting the above scheme, the device is placed on the rail using an electric push rod, marking sponge, data acquisition unit, and data analyzer. Utilizing a fixed base, rotating shaft, and balance wheel, the device collects information from the rail and transmits it to the data analyzer via a connecting cable. The electric push rod drives the marking sponge to move, enabling on-the-spot marking. This allows the device to mark the rail surface according to its unevenness, eliminating the need for manual marking and increasing the accuracy of inspections. Furthermore, it avoids repeated manual marking and improves the efficiency of inspection and maintenance.

[0007] In the above scheme, it should be noted that the data analyzer, data acquisition unit and electric actuator are all electrically connected to an external power source.

[0008] In a preferred embodiment, a U-shaped slide rod is installed on the front side of the fixed base, and an L-shaped movable plate is rotatably mounted on the slide rod. A groove is formed on the upper surface of the movable plate, and a U-shaped wiping cotton plate is disposed in the groove.

[0009] By adopting the above scheme, a movable plate and a wiping cotton plate are set up. The movable plate is movably supported on the fixed base by the action of the sliding rod. The wiping cotton plate is placed in conjunction with the groove and wipes the rail of the track, thereby improving the accuracy of the inspection.

[0010] In a preferred embodiment, a fixing rod is slidably installed through both the left and right sides of the movable plate, and a fixing groove is provided on both the left and right sides of the wiping cotton plate, with one end of the fixing rod extending into the fixing groove.

[0011] By adopting the above scheme, by setting a fixing rod, the fixing rod slides on the movable plate, and in conjunction with the fixing groove, it is convenient to fix the wiping cotton board, and the fixing rod can be moved out of the fixing groove at any time to disassemble the wiping cotton board.

[0012] In a preferred embodiment, baffles are installed on the front sides of both fixed seats, and the upper surface of the baffles abuts against the movable plate.

[0013] By adopting the above scheme, by setting up a baffle, and utilizing the baffle's position below the movable plate, when the movable plate rotates downwards to a horizontal state, the supporting force of the baffle supports the movable plate, thereby improving the stability of the movable plate.

[0014] In a preferred embodiment, two support plates are installed on the rear side of the movable plate, and a fixing rod is slidably installed through the support plates. Two fixing grooves are provided on the upper surface of the fixing seat to cooperate with the fixing rods, and the bottom end of the fixing rod is located in the fixing groove.

[0015] By adopting the above scheme, by setting up a support plate and a second fixing rod, the support plate supports the second fixing rod. Combined with the cooperation between the second fixing rod and the second fixing groove, the movable plate can be fixed on the fixed seat when not in operation, thereby preventing the movable plate from hindering the movement of the fixed seat.

[0016] In a preferred embodiment, the top ends of the two fixing rods are fitted with the same connecting plate, and springs are sleeved on the fixing rods, with their two ends respectively fixedly connected to the connecting plate and the support plate.

[0017] By adopting the above scheme, by setting a connecting plate and a spring, the two fixed rods are connected together using the function of the connecting plate, which facilitates the simultaneous operation of the two fixed rods. Combined with the elasticity of the spring, the fixed rods can be reset on their own while preventing them from falling off the support plate.

[0018] In a preferred embodiment, the upper surface of the marking sponge is fitted with an ink reservoir with openings on both the upper and lower sides, and the two ink reservoirs are located on the front and rear sides of the mounting plate, respectively.

[0019] By adopting the above solution, an ink storage cylinder is set up to store the ink required for marking. This allows the ink storage cylinder to deliver ink to the marking sponge in a timely manner, ensuring that the marking sponge can perform marking work normally.

[0020] In a preferred embodiment, a pull plate is installed at the other end of the fixing rod, and a U-shaped operating rod is installed on the upper surface of the connecting plate.

[0021] By adopting the above scheme, a pull plate and an operating lever are set up. The pull plate allows the operator to easily move the first fixed rod, thus making the operation convenient. Combined with the operating lever, the operator can easily move the connecting plate and thus the second fixed rod, resulting in a simple structure.

A data acquisition unit 8 is mounted on the inner top surface of the fixed seats 1. Both data acquisition units 8 are electrically connected to the data analyzer 4 via connecting wires. The data acquisition units 8 are located between the two rotating shafts 6 on the same side. The same mounting plate 12 is mounted on the upper surface of the two fixed seats 1, and the mounting plate 12 is located on the rear side of the fixed frame 2. An electric push rod 9 is installed on the upper surface of the mounting plate 12. The output shaft of the electric push rod 9 extends through to the bottom of the mounting plate 12 and a marking sponge 10 is installed thereon. By setting up the electric push rod 9, the marking sponge 10, the data acquisition device 8, and the data analyzer 4, and using the action of the fixed base 1, the rotating shaft 6, and the balance wheel 7, the device is placed on the rail. The data acquisition device 8 collects information from the rail and transmits it to the data analyzer 4 for analysis via a connecting line. With the help of the electric push rod 9 driving the marking sponge 10 to move, marking can be performed at any time. This allows the device to mark the rail surface according to its unevenness during use, avoiding manual marking and thus increasing the accuracy of the inspection. It also avoids multiple manual markings and further improves the efficiency of inspection and maintenance.

[0030] A U-shaped slide bar 13 is installed on the front side of the fixed base 1. An L-shaped movable plate 14 is rotatably mounted on the slide bar 13. A groove is opened on the upper surface of the movable plate 14, and a U-shaped wiping cotton plate 15 is set in the groove. By setting the movable plate 14 and the wiping cotton plate 15, the movable plate 14 is movably supported on the fixed base 1 by the slide bar 13. Combined with the function of the groove, the wiping cotton plate 15 is placed and used to wipe the rail of the track, thereby improving the accuracy of the inspection.

[0031] Fixing rods 17 are slidably installed on both sides of the movable plate 14. Fixing grooves are provided on both sides of the wiping cotton plate 15. One end of the fixing rods 17 extends into the fixing grooves. By setting the fixing rods 17, the wiping cotton plate 15 can be easily fixed by sliding the fixing rods 17 on the movable plate 14 and by using the fixing grooves. At the same time, the fixing rods 17 can be moved out of the fixing grooves at any time to disassemble the wiping cotton plate 15.

[0032] Both fixed seats 1 are equipped with baffles 16 on their front sides. The upper surface of the baffles 16 abuts against the movable plate 14. By setting the baffles 16, the movable plate 14 is supported by the supporting force of the baffles 16 when it rotates downward to a horizontal state, thereby improving the stability of the movable plate 14.

[0033] Two support plates 19 are installed on the rear side of the movable plate 14. A fixing rod 20 is slidably installed through the support plate 19. Two fixing grooves 2 are provided on the upper surface of the fixing seat 1 to cooperate with the fixing rod 20. The bottom end of the fixing rod 20 is located in the fixing groove 2. By setting the support plate 19 and the fixing rod 20, the support plate 19 supports the fixing rod 20. Combined with the cooperation of the fixing rod 20 and the fixing groove 2, it is convenient to fix the movable plate 14 on the fixing seat 1 when it is not working, thereby avoiding the movable plate 14 from hindering the movement of the fixing seat 1.

[0034] The top ends of the two fixed rods 20 are equipped with the same connecting plate 22. The fixed rods 20 are fitted with springs 21, which are fixedly connected to the connecting plate 22 and the support plate 19 at their two ends respectively. By setting the connecting plate 22 and the springs 21, the two fixed rods 20 are connected together by the function of the connecting plate 22, which makes it convenient to operate the two fixed rods 20 at the same time. Combined with the elasticity of the springs 21, the fixed rods 20 can be reset by themselves while preventing the fixed rods 20 from falling off the support plate 19.

[0035] The upper surface of the marking sponge 10 is equipped with ink reservoirs 11 that are open on both the top and bottom sides. The two ink reservoirs 11 are located on the front and rear sides of the mounting plate 12, respectively. By setting up the ink reservoirs 11, the ink required for marking is stored, which facilitates the timely delivery of ink to the marking sponge 10, ensuring that the marking sponge 10 can perform marking work normally.

[0036] A pull plate 18 is installed at the other end of the fixing rod 17, and a U-shaped operating rod 23 is installed on the upper surface of the connecting plate 22. By setting the pull plate 18 and the operating rod 23, the pull plate 18 facilitates the movement of the fixing rod 17 by the operator, thus making the operation convenient. Combined with the operating rod 23, the operating rod 23 facilitates the movement of the connecting plate 22 by the operator, thus moving the fixing rod 20, thus simplifying the structure.

[0037] In use, the marking ink is placed in the ink reservoir 11, and the fixing base 1 is placed on the two steel rails of the track. The fixing base is supported by the balance wheel 7. The operating lever 23 is moved upward, which drives the connecting plate 22 to move. The connecting plate 22 drives the fixing rod 20 to move upward, and the connecting plate 22 stretches the spring 21. At this time, the bottom end of the fixing rod 20 gradually moves out of the fixing groove. Then, the movable plate 14 is rotated, changing the movable plate 14 from a vertical state to a horizontal state. At this time, the movable plate 14 is supported by the baffle 16. The wiping cotton board 15 wraps around the steel rail, and then... The worker holds handle 5 and starts the data acquisition unit 8 and data analyzer 4. As the worker moves, the fixed base 1 moves on the rail. The wiping cotton board 15 wipes the stains on the rail. The data acquisition unit 8 collects information on the rail and transmits the detection information on the rail to the data analyzer 4 in real time through the connecting line. When the data analyzer 4 analyzes the location of the rail that needs maintenance, it starts the electric push rod 9. The electric push rod 9 drives the marking sponge 10 to move downward. The marking sponge 10 absorbs the ink in the ink storage cylinder 11 to mark the rail, thus saving the labor of manual marking.
