Description

Technical Field

[0001] The utility model relates to the technical field of rail processing, in particular to a rail spraying device. Background Art

[0002] As a basic component of rail transportation, rails need to be treated with corrosion protection and insulation due to their steel material characteristics to ensure long-term safe and reliable performance. Additional coating is mainly used, especially in DC electric transportation track line systems, where rails are needed as return circuits. The insulation performance of rails to the ground is very important. Since the environment in which return rails are located is often complex and harsh, stray currents are easily formed. The stray currents will not only cause electrical corrosion to the rail steel structure and metal pipes along the line, but also lead to excessively high grounding potentials, making other grounding equipment unable to work normally. Therefore, under-rail insulation pads are usually set at the bottom of the rails, and the main locations for spraying insulating materials are the side surfaces of the rail waist and the upper surface of the rail bottom.

[0003] At present, handheld spraying tools are mostly used for rail spraying. This method has low work efficiency, is time-consuming and labor-intensive, and is prone to unqualified coating performance due to uneven spraying. Of course, there are also optional spraying devices, which can often only spray one side at a time, and the work efficiency is still relatively low. In addition, the relative stability of the device and the rail is difficult to control during operation, which affects the spraying effect. Chinese patent publication number CN217569297U, publication date October 14, 2022, named "A rail anti-corrosion coating device" discloses a device that can be used to apply a coating to a rail, including a machine body, a spraying mechanism and a conveyor platform. The conveyor platform is provided with guide rollers to push the rails on the conveyor platform through the spraying mechanism for anti-corrosion coating. However, the device provided by this patent places the rails on the conveyor platform and cooperates with the spraying mechanism by sliding the rails. The conveyor platform needs to have a large length to avoid one end of the rail falling, resulting in a large overall size of the device, which is inconvenient to move and transport. Each rail needs to be moved to the conveyor platform, which is time-consuming and labor-intensive, and the spraying mechanism can only spray one side of the rail at a time, resulting in low work efficiency.

[0025] like Figure 1-3 As shown, the rail spraying device provided by the utility model comprises:

[0026] The support frame 1 adopts a rectangular frame structure and is provided with a push-pull handrail 2; the length and width of the rectangular frame are consistent with the length and width of the rail 4, and the two sides of the rectangular frame are symmetrical relative to the rail 4. The push-pull handrail 2 is arranged at the end of the rectangular frame, similar to the shape of the handrail of a trolley.

[0027] The rolling support wheel group includes a pair of rollers 3 connected to the support frame 1, the rollers 3 are supported on the rail head of the rail 4 one after the other, and both ends of the rollers 3 are provided with anti-deviation protruding structures 5 clamped on both sides of the rail head; the rail head part of the rail 4 is usually high in the middle and low on both sides, and the contour of the roller 3 is set to fit on the rail head, so it is set to a shape in which the wheel diameter gradually decreases from both ends to the middle, and the anti-deviation protruding structures 5 at both ends of the roller 3 are protruding parts in the vertical direction, wrapped on both sides of the rail head, and the shafts of the rollers 3 extend from both ends and are connected to the lower side of the support frame 1 through two clamped support blocks.

[0028] The sliding limiting wheel group includes a limiting rod 6 and a pulley 7. The limiting rods 6 are connected in pairs under the support frame 1 and extend downward to both sides of the bottom of the rail 4. The pulley 7 is laterally connected to the inner side of the lower end of the limiting rod 6. A pair of pulleys 7 are respectively against both sides of the bottom of the rail 4. The sliding direction of the pulley 7 is the extension direction of the rail 4. The spacing between the support rods is greater than the bottom width of the rail 4 to provide installation space for the pulley 7. The pulley 7 is arranged close to the bottom of the rail 4 to form a left and right supporting structure to prevent the device from tilting on the rail 4. The bottom of the limiting rod 6 is a distance away from the ground to avoid the phenomenon of dragging obstruction when using the device. The side of the limiting rod 6 can also be provided with a downward pulley 7 so that it can be supported on the ground to slide forward.

[0029] The paint spraying assembly includes a paint pump 8, a paint tank 9, a nozzle 10 and a nozzle 11. The paint pump 8 is fixed on the support frame 1. The feed port of the paint pump 8 is connected to the paint tank 9, and the discharge port is connected to the upper port of the nozzle 10. The nozzle 10 extends downward to both sides of the waist of the rail 4. The nozzle 11 is connected to the lower port of the nozzle 10, and the nozzle 11 faces the area to be sprayed on the rail 4. The paint pump 8 can use a small vacuum pump. The length direction of the paint pump 8 is along the extension direction of the rail 4, which can achieve a better symmetrical balance effect. The paint pump 8 is connected to a pipeline integration module above the flange structure. The paint tank 9 is vertically installed on the pipeline integration module and is connected to the feed port of the paint pump 8 through the module. The discharge port of the paint pump 8 is divided into a nozzle 10 on both sides through the pipeline integration module. The nozzle 10 extends downward from the hollow part of the support frame 1 to the spraying working area on both sides of the waist of the rail 4. The direction of the nozzle 11 can be adjusted and locked.

[0030] When using this device to perform coating addition operation on the rail 4, it is only necessary to place the rail 4 on a flat ground, align the roller 3 of the device with the rail head at one end of the rail 4 and place it so that the pulley 7 of the sliding limit wheel group bears against both sides of the bottom of the rail 4, start the paint pump 8 and push or pull the push-pull handrail 2 by hand to move the device to the other end of the rail 4. When the device has finished spraying the rail 4 once, turn off the paint pump 8 and wait for a while. After the paint solidifies, start the paint pump 8 again to move the device back on the rail 4. Repeat this process many times until the coating reaches the expected qualified thickness. In some cases, when it is necessary to use this device to spray the bottom of the rail 4, support members can be set at both ends of the rail 4 to lift the rail 4, and the nozzle 10 can be extended to a position below the bottom of the rail 4, and the nozzle 11 can be adjusted to align with the position to be sprayed; when it is necessary to spray the positions where the two sides of the bottom of the rail 4 contact the pulley 7, the positions of the nozzle 10 and the nozzle 11 are adjusted to the rear of the pulley 7 during this sliding, so that the pulley 7 will not affect the spraying effect, and the position where the pulley 7 contacts the rail 4 is made of elastic and smooth material to avoid scratching the solidified paint.

[0031] The rail spraying device uses a roller 3 with an anti-bias protruding structure 5. The device is mounted on the rail head of the rail 4, and the device can slide along the rail 4, which is simple and labor-saving to operate. By arranging sliding limit wheel groups on both sides, the pulleys 7 clamp the two sides of the rail bottom of the rail 4, and the parts of the spraying device located on both sides of the rail 4 are symmetrically distributed, with good balance, which reduces the difficulty of straightening when using the device, and the device runs more smoothly and smoothly. The coating after spraying is more uniform, ensuring the processing quality. The device adopts a structure similar to a trolley, which is simple, light and small in size, and is convenient to adjust according to the position of the rail 4. The device can be moved and matched and can be processed on the spot, avoiding the trouble of adjusting the position of the rail 4. In particular, for the used rail 4, the coating performance has deteriorated and needs to be re-sprayed. At this time, it is only necessary to remove the rail 4, grind it and lay it flat. The coating can be quickly added using this device, and there is no need to transport the rail 4 to the vicinity of the processing equipment, making the spraying of the rail 4 convenient and quick. The rectangular frame structure adopted by the device can be equipped with paint nozzles 11 on both sides and the direction of the nozzle 10 and the position of the nozzle 11 can be flexibly adjusted, thereby realizing the synchronous spraying processing of the two sides of the rail 4.

[0032] In another technical solution, Figure 2 As shown, the limit rod 6 is provided with two pairs, and the two pairs of limit rods 6 are respectively arranged near the front roller 3 and the rear roller 3. By arranging two pairs of limit rods 6 and four pulleys 7, the device moves more stably on the rail 4 without being easily deflected.

[0033] The support frame 1 is provided with a support plate 12, and the paint pump 8 is fixed on the support plate 12. When the paint pump 8 is installed on the support frame 1, it can be directly installed on the transverse rod provided in the middle of the support frame 1, and by providing the support plate 12, a suitable installation table can be provided for paint pumps 8 of different shapes, sizes and models, so that the paint pump 8 can be installed more firmly and run more stably.

[0034] In another technical solution, Figure 3 As shown, baffles 13 are provided on both sides of the support frame 1, and the baffles 13 are bolted to the outside of the limit rod 6. Since the limit rod 6 is vertically downward, by fixing the baffles 13 on the outside of the limit rod 6, a cover-like structure is formed on both sides of the support frame 1, which can reduce the diffusion of paint to the outside during the spraying process.

[0035] The pulley 7 is connected to the limit rod 6 through a spring rod 14. The contact between the pulley 7 and the rail 4 is relatively close. By utilizing the elasticity of the spring rod 14, the distance between the pulleys 7 on both sides can be adaptively changed. By compressing the spring rod 14, the pulley 7 can be more conveniently adjusted to a suitable position on the side of the rail bottom. In the natural state, the spring rod 14 is extended to make the pulley 7 and the rail 4 fit more closely.

[0036] In another technical solution, Figure 1 As shown, the spray heads 11 are provided in plurality, and the plurality of spray heads 11 are respectively aimed at the rail waist and rail bottom of the rail 4. The plurality of spray heads 11 can cover a larger range of the area to be sprayed of the rail 4, improve the spraying efficiency, and realize the refined control of the spraying position and the spraying amount.

[0037] like Figure 2 As shown, both front and rear ends of the support frame 1 are provided with push-pull handrails 2. Each push-pull handrail 2 can be pushed or pulled, and only one push-pull handrail 2 is used to switch between pushing and pulling to realize the back and forth movement of the device on the rail 4. For people who are only accustomed to pushing or pulling the device, they can switch to use the two handles to complete the operation by only pushing or only pulling the device, which is more flexible to use and provides a better operating experience.
