DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0042] Reference Figure 1-Figure 4 The utility model proposes a technical solution for a corrosion protection coating spraying equipment for railway tracks, comprising: a track trolley 1, above which a spraying mechanism 2 for spraying the surface of the railway track is fixedly arranged.

[0043] Among them, the spraying mechanism 2 includes: a first paint tank 3, a second paint tank 4, a paint conveying mechanism 5 and a paint nozzle 6. The first paint tank 3 and the second paint tank 4 are both fixedly arranged above the rail cart 1, and the second paint tank 4 and the first paint tank 3 are arranged parallel to each other. One end of the paint conveying mechanism 5 is simultaneously connected to the output ends of the first paint tank 3 and the second paint tank 4, and the other opposite end of the paint conveying mechanism 5 can be partially extended to the outside of the rail cart 1, and is transmission-connected to the driving source provided outside the rail cart 1. The paint nozzle 6 is symmetrically arranged on both sides of the paint conveying mechanism 5, and is arranged in a cross-staggered structure with the paint conveying mechanism 5. One end of the paint nozzle 6 is connected to the paint mixing pipe 7 in the middle of the paint conveying mechanism 5, and the other opposite end of the paint nozzle 6 is in contact with the conical guide part 8 on the outer periphery of the rail cart 1, so that it can be partially extended to the outside of the rail cart 1, and the paint spraying surface in the above-mentioned paint nozzle 6 is arranged below the rail cart 1 in the vertical direction, which is used to evenly spray the surface of the railway track.

[0044] In this embodiment, on the one hand, by connecting the paint conveying mechanism 5 to the driving source, an automated paint conveying process can be realized, reducing manual intervention and improving work efficiency. At the same time, through the control of the external driving source, the conveying speed and pressure can be adjusted according to actual needs to adapt to different environments and requirements.

[0045] On the other hand, the provision of the first paint tank 3 and the second paint tank 4 allows for the storage of two different paints or two compartments of the same paint, increasing the flexibility of operation. It is also possible to achieve one-time application of two or more layers of coating, or when one tank needs to be replenished, the other tank continues to provide paint supply, thereby not interrupting the spraying operation.

[0046] At the same time, since the coating nozzle 6 is arranged below the rail trolley 1 and arranged in the vertical direction, it can ensure uniform spraying of the surface of the railway track. This layout helps to evenly distribute the coating, prevents missing or repeated coating, and improves the coverage quality and anti-corrosion performance of the coating.

[0047] In one embodiment, the first coating tank 3 and the second coating tank 4 have the same structure.

[0048] Specifically, the first coating tank 3 at least comprises a material storage portion 9 and a material discharge guide portion 10 , and the material discharge guide portion 10 is disposed below the material storage portion 9 .

[0049] For example, the feed guide portion 10 includes: a first conical feed portion 11 and a second conical feed portion 12, the first conical feed portion 11 and the second conical feed portion 12 are arranged in sequence below the material storage portion 9 along the vertical direction, the conical surface slope of the second conical feed portion 12 is greater than the conical surface slope of the first conical feed portion 11, and a paint mixing portion 13 is connected between the first conical feed portion 11 and the second conical feed portion 12.

[0050] Among them, the paint stirring part 13 includes: a stirring rod 14, a rotating motor 15 and a paint stirring chamber 16. The paint stirring chamber 16 is arranged between the unloading port of the first conical unloading part 11 and the loading port of the second conical unloading part 12. The rotating motor 15 is arranged on the side wall outside the paint stirring chamber 16. One end of the stirring rod 14 is rotatably connected to the output end of the rotating motor 15, and the other opposite end of the stirring rod 14 can partially extend axially into the paint stirring chamber 16 to ensure smooth transportation and uniform mixing of the paint.

[0051] In addition, the stirring rod 14 can be provided with blades of a specific shape and arrangement, which can create eddies during rotation to promote uniform mixing within the coating. The length and blade angle of the stirring rod 14 are precisely calculated to adapt to the viscosity and flow properties of the coating, ensuring that the optimal mixing effect can be achieved under different working conditions.

[0052] In this embodiment, by setting two conical feeding parts with different slopes, the flow speed of the paint can be more effectively controlled to prevent bubbles or unevenness when the paint flows quickly. At the same time, the design of the paint stirring part 13 ensures that the paint can be fully stirred during the transition from the storage part 9 to the feeding guide part 10 to achieve uniformity of the composition. The combination of the stirring rod 14 and the rotating motor 15 can create an effective eddy current in the stirring chamber, further improving the efficiency and quality of the paint mixing, and improving the uniformity and adhesion of the final coating through the uniformly mixed paint, thereby extending the service life of the railway track and reducing the number of repairs caused by coating problems.

[0053] At the same time, since the stirring rod 14 and the rotating motor 15 are designed to be easy to clean and maintain, this reduces long-term operating costs, simplifies the maintenance process, and improves the reliability of the equipment. The automated stirring and conveying process reduces the need for manual operation, improves overall work efficiency, and reduces the risk of errors and accidents caused by human factors.

[0054] In one embodiment, the paint conveying mechanism 5 includes: a drive motor 17, a motor mounting frame 18, a paint conveying pipe 19 and a paint uniform stirring member 20. The number of the paint conveying pipes 19 is 2, and they are respectively connected to the discharge ports at the lower ends of the first paint tank 3 and the second paint tank 4. The paint uniform stirring member 20 is arranged in the middle of the rail trolley 1, and one end of the paint uniform stirring member 20 is connected to the above-mentioned two paint conveying pipes 19 at the same time, and the other opposite end of the paint uniform stirring member 20 is connected to the paint mixing pipe 7, and a spiral stirring rod 21 extending along its long axis direction is arranged in the paint mixing pipe 7, one end of the spiral stirring rod 21 is rotatably connected to the rotating blade in the paint uniform stirring member 20, and the other opposite end of the spiral stirring rod 21 can partially extend to the outside of the paint mixing pipe 7, the motor mounting frame 18 is fixedly arranged on the outside of the rail trolley 1, the drive motor 17 is fixedly arranged on the motor mounting frame 18, and the output shaft of the drive motor 17 is rotatably connected to the spiral stirring rod 21 extending to the outside of the paint mixing pipe 7.

[0055] In this embodiment, two paint delivery pipes 19 are provided to be connected to the first paint tank 3 and the second paint tank 4 respectively, so that the two paints can be delivered at the same time, which improves the work efficiency and reduces the operation interruption caused by switching the paint source. The paint uniform stirring member 20 arranged in the middle of the rail trolley 1 can simultaneously receive the paints from the two pipes and perform preliminary mixing. Such a layout simplifies the equipment structure and reduces the complexity of the stirring process. At the same time, the spiral stirring rod 21 extending along the long axis direction of the paint mixing pipe 7, in conjunction with the rotating blades, provides a strong stirring effect, so that the paints of different components can be mixed more thoroughly, thereby ensuring the uniformity of the paint during the final spraying.

[0056] Since one end of the spiral stirring rod 21 can partially extend to the outside of the paint mixing pipe 7 and is rotatably connected to the drive motor 17, this design facilitates monitoring and maintenance of the stirring components, helps to detect potential problems in a timely manner, and reduces equipment failure rates.

[0057] To sum up, the paint delivery mechanism 5 in this embodiment, by combining advanced stirring technology and a precise power transmission system, not only significantly improves the mixing uniformity and delivery efficiency of the paint, but also enhances the versatility and reliability of the equipment, providing a strong guarantee for high-quality railway track protective coatings.

[0058] In one embodiment, the rail trolley 1 includes: a trolley body 22, a trolley handle 23 and a rail pulley 24. The trolley handle 23 is fixedly connected to one end of the trolley body 22 away from the paint delivery mechanism 5. There are 4 rail pulleys 24, all of which are fixedly arranged below the trolley body 22. A rail slide groove 26 that cooperates with the upper end surface of the railway track is opened in the rolling surface of the rail pulley 24. The matching surface of the rail slide groove 26 and the railway track is on the same axis as the paint spraying surface of the paint nozzle 6.

[0059] In this embodiment, the track slide groove 26 can be matched with the upper end surface of the railway track and aligned with the paint nozzle 6. The matching design of the track slide groove 26 and the upper end surface of the railway track ensures that the rail trolley 1 can move accurately along the predetermined trajectory without deviation, thereby improving the accuracy and repeatability of the operation. The alignment setting of the paint nozzle 6 and the track slide groove 26 can achieve high-precision spray positioning, so that the paint can be directly and evenly applied to the surface of the railway track, avoiding the problem of offset or uneven spraying.

[0060] By fixing four track pulleys 24 under the trolley body 22, a larger support area and better weight distribution are provided, making the track trolley 1 more stable during travel and reducing the risk of shaking or rollover due to instability. At the same time, the presence of the track chute 26 limits the possible lateral movement or sliding of the trolley, further ensuring the safety of the operator, especially during high-speed operation or emergency braking.

[0061] The provision of the trolley handle 23 also enables the operator to easily push or control the movement of the rail trolley 1, thereby reducing labor intensity and improving operating comfort.

[0062] In one embodiment, the paint nozzle 6 is arranged between the track pulleys 24 at both ends of the cart body 22, and a circle of paint drying light belt 25 is arranged on the outer edge of the inner wall of the track pulley 24 at one end of the cart body 22 away from the paint conveying mechanism 5.

[0063] Specifically, the number of the paint nozzles 6 is at least 5, which are arranged side by side on the outside of the paint mixing pipe 7.

[0064] In this embodiment, on the one hand, multiple paint nozzles 6 arranged side by side can ensure uniform distribution of paint on the railway track, avoiding the problem of local thick or thin coating caused by single-point spraying, ensuring the uniformity and quality of the coating, and multiple paint nozzles 6 can work simultaneously with the movement of the track trolley 1 to form a continuous spraying surface and provide uninterrupted coverage, which is particularly important for long-distance railway track maintenance.

[0065] On the other hand, the paint drying light belt 25 arranged on the outer edge of the inner wall of the track pulley 24 can instantly heat the coating just sprayed, accelerating the curing and drying process of the coating, thereby shortening the entire operation cycle and improving work efficiency. At the same time, the use of the drying light belt reduces the potential danger caused by solvent volatilization, and also reduces the potential safety hazards caused by waiting for a long time for the coating to dry naturally.

[0066] Working principle:

[0067] First, the first paint tank 3 and the second paint tank 4 store the paint to be used, wherein the paint used can be the same kind of paint or different kinds of paint.

[0068] Then the driving motor 17 transmits power to the spiral stirring rod 21 through the rotating shaft, thereby driving the paint to flow in the pipeline. The paint is transported from the first and second paint tanks 4 to the paint uniform stirring member 20, and then enters the paint mixing pipeline 7.

[0069] Further, during the conveying process, the paint passes through the paint uniform stirring member 20 disposed in the middle of the rail trolley 1, which includes a rotating blade and a spiral stirring rod 21, for preliminary mixing.

[0070] Subsequently, the paint flows into the paint mixing pipe 7, where it is further stirred and mixed by the spiral stirring rod 21 to ensure the uniformity of the paint.

[0071] The uniformly mixed paint is delivered to each paint nozzle 6. The nozzle is arranged between the track pulleys 24 at both ends of the track trolley 1 and arranged in the vertical direction so that the paint can be evenly sprayed on the surface of the railway track below.

[0072] As the track trolley 1 moves, the sprayed paint forms a continuous coating. A paint drying light belt 25 is provided at the outer edge of the inner wall of the track pulley 24 at one end of the track trolley 1. When the spraying is completed, the drying light belt instantly heats the coating to accelerate the curing and drying process of the coating.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
