Technical Field

[0001] This utility model relates to the technical field of railway casting information marking spraying device, specifically a railway casting information marking spraying device. Background Technology

[0002] As a key component of the railway transportation system, railway castings encompass hundreds of categories, including sleepers, connectors, and brake shoes. The forms of castings vary among different categories. Furthermore, in railway transportation safety management, information such as the production batch, material type, and maintenance date of castings is the core basis for tracing quality and ensuring operation and maintenance. Therefore, there are stringent requirements for the clarity, durability, and positional accuracy of the markings.

[0003] Currently, the spraying of information markings on railway castings is mainly done manually with handheld spray guns. However, this method is affected by the skill differences of the operators, often resulting in problems such as skewed fonts, missed sprays, and uneven ink coverage. These issues require a lot of manual re-inspection and correction, which in turn affects production efficiency. Therefore, a railway casting information marking spraying device is proposed to address these problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figure 1-6 As shown, a railway casting information marking spraying device includes two side plates 1, two support shafts 11 are rotatably mounted between the two side plates 1 and located below their sides, and two take-up rollers 12 are rotatably mounted between the two side plates 1, with the two take-up rollers 12 located above the outer sides of the two support shafts 11 respectively. A transmission belt 13 is wound on one of the take-up rollers 12, and the end of the transmission belt 13 is wound around the lower part of the two support shafts 11 and connected to the other take-up roller 12.

[0029] A nozzle plate 15 is fixed between the two side plates 1 and between the two support shafts 11, and the working end of the nozzle plate 15 faces the transmission belt 13.

[0030] The rotation center shafts of the two winding rollers 12 are both arranged through the outer sides of the two side plates 1 and are respectively provided with transmission components 2. The two transmission components 2 located on the same side are respectively connected to drive rollers 4.

[0031] The two ends of the transmission belt 13 are respectively attached and fixed to the two take-up rollers 12. The nozzle plate 15 is fixed with a feeding hose 16 connected to it, and the end of the feeding hose 16 is connected to the external storage tank. The transmission belt 13 has an identification font 14.

[0032] The transmission assembly 2 includes a fixed seat 21 fixed on the side wall of the side plate 1. An inner spline sleeve 22 is rotatably installed inside the fixed seat 21. The top end of the fixed seat 21 is connected to the central shaft of the take-up roller 12 via a gear. A telescopic rod 25 is slidably telescopically installed inside the fixed seat 21. A connecting frame 26 is rotatably installed at the bottom end of the telescopic rod 25. The drive roller 4 is rotatably installed between the bottom ends of the two connecting frames 26 located on the same side.

[0033] A first annular plate 23 is rotatably mounted at the bottom port of the inner spline sleeve 22, and the telescopic rod 25 is inserted through the hole in the middle of the first annular plate 23. A spline shaft 24 is fixedly connected to the end of the telescopic rod 25 inside the inner spline sleeve 22, and the spline shaft 24 is slidably fitted inside the inner spline sleeve 22. A second annular plate 27 is rotatably mounted on the telescopic rod 25, and the second annular plate 27 is located above the connecting frame 26. A spring 28 is sleeved on the outside of the telescopic rod 25, and the spring 28 is located between the first annular plate 23 and the second annular plate 27.

[0034] Both ends of the drive roller 4 are fixedly connected to the rotation center of each other, and the ends of the two connecting shafts 41 are respectively rotatably installed under the connecting frame 26 located on both sides. The two side plates 1 are jointly fixedly connected to the gripping frame 3.

[0035] The bottom ends of the telescopic rods 25 are respectively connected to the connecting shafts 41 rotatably mounted under the same connecting frame 26 via gears. A square rod 29 is fixedly connected to the side of the connecting frame 26. A fixing buckle 210 is slidably provided on the square rod 29 and the fixing buckle 210 is fixedly connected to the side wall of the side plate 1. A limit block 211 is fixedly connected to the top of the square rod 29. A fastening bolt 212 is threadedly connected to one side of the connecting frame 26.

[0036] A partition plate 18 is fixed between the two side plates 1 and on both sides of the nozzle plate 15, and the partition plate 18 is located inside the support shaft 11. A sponge block 17 is fixed between the two side plates 1 and on the outside of the two partition plates 18, and both sponge blocks 17 intersect with the transmission trajectory on the upper surface of the transmission belt 13. Both sponge blocks 17 are located inside the two support shafts 11.

[0037] During operation, due to the differences in operator skills, the existing manual handheld spray gun operation often results in problems such as slanted characters, missed sprays, and uneven ink stains. A large amount of manual re-inspection and correction is required afterward, which affects production efficiency. In this solution, in the initial state, the spring 28 will always push the second annular plate 27 downward to keep the second annular plate 27 away from the first annular plate 23, so that the telescopic rod 25 can extend out of the inner spline sleeve 22, thereby keeping the drive roller 4 always below the lower transmission surface of the transmission belt 13.

[0038] The end of the drive belt 13 is attached to one of the take-up rollers 12 and the drive belt 13 is wound around it. Then the fastening bolt 212 is tightened to make the connecting shaft 41 rotate and generate resistance, so that the drive roller 4 will not rotate without the action of external force. Then the other end of the drive belt 13 is wound around under the two support shafts 11 and attached to the other take-up roller 12.

[0039] In use, the operator holds the grip 3 and places the device on the casting where the marking needs to be sprayed. Simultaneously, pressing the device causes the telescopic rods 25 on both sides to retract into the inner spline sleeve 22, and the spline shaft 24 to slide within the inner spline sleeve 22. When the telescopic rods 25 retract, the rolling surfaces of the two drive rollers 4 become flush with the lower transmission surface of the transmission belt 13. Supported by the two support shafts 11, the lower transmission surface of the transmission belt 13 adheres to the surface of the casting. The device is then pushed to move on the surface of the casting. During this movement, the delivery pump is controlled to transport the spray material from the external storage tank to the nozzle plate 15. As the device moves, the two drive rollers 4 roll on the surface of the casting, and their rolling motion drives the two take-up rollers 12 to rotate in the same direction. The transmission belt 13, which is wound on one of the take-up rollers 12, is then gradually wound onto the other take-up roller 12. During the conveying process, the transmission belt 13 passes under the two support shafts 11, and the required marking font 14 is set on the transmission belt 13. At this time, the pigment sprayed by the nozzle plate 15 can penetrate the hollow marking font 14 and coat the surface of the casting. As the transmission belt 13 is conveyed, the marking information on the transmission belt 13 can be coated onto the surface of the casting in the order of the hollow marking font 14. This method is suitable for marking and spraying large castings. The painted markings are arranged along the pushing direction of the device. Compared with the traditional handheld spray gun, it is more beautiful and effectively avoids problems such as skewed fonts, missed sprays, and uneven ink, thus improving the spraying efficiency.

[0040] In addition, when the drive roller 4 rolls, it will drive the telescopic rod 25 to rotate through the connecting shaft 41. When the telescopic rod 25 rotates, it will drive the inner spline sleeve 22 to rotate through the spline shaft 24. When the inner spline sleeve 22 rotates, it can drive the take-up roller 12. With the help of the spring 28, it can ensure that the drive roller 4 can accurately fit against the surface of the casting and roll, and ensure that the telescopic rod 25 can accurately drive the take-up roller 12 when it extends and retracts inside the inner spline sleeve 22.

[0041] It achieves the purpose of information labeling spraying, and is more efficient than traditional handheld spray guns. It effectively avoids problems such as skewed fonts, missed spraying, and uneven ink coverage, and the ink spraying is more uniform, resulting in a better spraying effect.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
