Description

Technical Field

[0001] This utility model specifically relates to a railway locomotive cleaning device, belonging to the field of locomotive cleaning technology. Background Technology

[0002] As the core equipment of rail transit, railway locomotives operate in complex environments such as wind, sand and oil pollution for a long time. The locomotive body and components are prone to the accumulation of pollutants such as dust, sand and carbon deposits. These pollutants not only affect the appearance of the locomotive, but also hinder the heat dissipation of components, accelerate metal corrosion, and even cause power system failures. Therefore, regular and efficient cleaning is a key link to ensure the safe operation and maintenance of locomotives.

[0003] Currently, most mainstream cleaning devices use a fixed-position nozzle structure, relying on high-pressure water flow to achieve rinsing. However, the rinsing range of a fixed-position nozzle is limited by the nozzle angle, resulting in a small coverage area on the side of the vehicle and poor rinsing effect. Furthermore, the impact force of the fixed water flow is uniform, making it difficult to efficiently remove stains.

[0004] To address the above problems, this application proposes a railway locomotive cleaning device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a railway locomotive cleaning device. This device utilizes a linkage mechanism constructed with a cam, a movable connecting rod, a linkage rod, and a vertical water pipe. The inner shaft of the brush roller serves as the transmission end, with the upper and lower cams rotating synchronously with the shaft. The cams, via the movable connecting rod, convert the circular motion into the linear reciprocating motion of the linkage rod, thereby driving the vertical water pipes on both sides to reciprocate within the outer ring. This causes the nozzles on the vertical water pipes to form a dynamic rinsing trajectory, thus solving the problems mentioned in the background art.

[0006] A railway locomotive cleaning device includes a housing, in which two sets of brush rollers are rotatably installed. A rotating shaft is installed inside the brush rollers. A set of cams is fixedly connected to the upper and lower ends of the rotating shaft. A movable connecting rod is rotatably connected to the side of the cam away from the rotating shaft. A linkage rod is rotatably connected to the end of the movable connecting rod away from the cam. A set of vertical water pipes is provided on both sides of the box. Multiple sets of nozzles are installed at intervals along the height direction on the front side of the vertical water pipes. A set of outer rings is fitted on the upper and lower sides of the vertical water pipes. The outer rings are rotatably connected to the vertical water pipes. A set of swing rods is fixed to the upper and lower ends of the vertical water pipes. The rear end of the swing rods is rotatably connected to the inner side of the linkage rod through a connecting shaft. A rotary joint is installed at the top of the vertical water pipes. The box body has a vertical plate on one side, which is obliquely positioned facing the direction of locomotive travel, and multiple DC fans are installed on the vertical plate along the height direction.

[0007] In a preferred embodiment, two sets of waterproof motors are installed on the top of the housing, and the output shafts of the two sets of waterproof motors are respectively connected to two sets of rotating shafts. The upper and lower sides of the rotating shafts are rotatably connected to the inside of the housing.

[0008] In a preferred embodiment, two sets of side fixing blocks are fixedly installed on both sides of the box, and the linkage rod is slidably connected to the side fixing blocks and the box.

[0009] In a preferred embodiment, the outer ring is fixedly connected to the housing via a connecting rod, and the diameters at the upper and lower ends of the water pipe are smaller than the diameter at the middle.

[0010] In a preferred embodiment, a base is installed below the box body, and the lower end of the upright plate is fixedly connected to the base.

[0011] In a preferred embodiment, the fixed part of the rotary joint is fixedly connected to the top of the water pipe, the rotating part is connected to the water inlet pipe, the water inlet pipe is fixedly connected to the box body through a fixing rod, and the rear end of the water inlet pipe is connected to the pump pipe.

[0012] In a preferred embodiment, the air inlet and air outlet of the DC fan are each equipped with a set of filter plates, and the surface of the filter plates has multiple sets of through holes.

[0013] Beneficial effects: 1. By designing cams, movable connecting rods, linkage rods, and vertical water pipes, the rotating shaft inside the brush roller serves as the transmission end. The cams at both ends rotate synchronously with the rotating shaft. The cams convert the circular motion into the linear reciprocating motion of the linkage rod through the movable connecting rod. The linkage rod then drives the vertical water pipes on both sides to reciprocate within the outer ring, causing multiple sets of nozzles on the vertical water pipes to form a dynamic rinsing trajectory. Compared with the limited rinsing range and poor rinsing effect of fixed nozzles in existing technologies, this design can improve the rinsing range without an additional power source. The reciprocating oscillation of the nozzles creates a dynamic impact of water flow, which can more efficiently remove dust and impurities compared to water flow in a fixed position, while reducing excessive impact of water flow in the same position, thus improving the cleanliness and uniformity of rinsing.

[0014] 2. By designing a vertical plate that is angled towards the direction of locomotive travel and installing a DC fan on the plate, when the locomotive travels along the predetermined route to the cleaning area, the angled fan can generate an airflow that blows onto the surface of the locomotive, blowing off most of the floating dust, sand, and other debris attached to the vehicle body in advance. This pre-blowing dust removal design can clean the vehicle body in advance. After the floating dust is removed in advance, the subsequent high-pressure water flow can directly act on stubborn stains such as oil and carbon deposits, reducing water waste and allowing the cleaning liquid to contact the stains more efficiently, thus shortening the overall cleaning time.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0018] Please see Figures 1-5 As shown, a railway locomotive cleaning device includes a housing 1, two sets of brush rollers 2 are rotatably installed inside the housing 1, a rotating shaft 15 is installed inside the brush rollers 2, a set of cams 14 are fixedly connected to the upper and lower ends of the rotating shaft 15 respectively, a movable connecting rod 16 is rotatably connected to the side of the cam 14 away from the rotating shaft 15, and a linkage rod 8 is rotatably connected to the end of the movable connecting rod 16 away from the cam 14. A set of vertical water pipes 3 are provided on both sides of the housing 1. Multiple sets of nozzles 5 are installed at intervals along the height direction on the front side of the vertical water pipes 3. A set of outer rings 4 are fitted on the upper and lower sides of the vertical water pipes 3 respectively. The outer rings 4 are rotatably connected to the vertical water pipes 3. A set of swing rods 17 are fixedly connected to the upper and lower ends of the vertical water pipes 3 respectively. The rear end of the swing rods 17 is rotatably connected to the inner side of the linkage rod 8 through the connecting shaft. A rotary joint 18 is installed at the top of the vertical water pipes 3. A vertical plate 11 is provided on one side of the housing 1. The vertical plate 11 is obliquely set towards the direction of locomotive travel, and multiple DC fans 12 are installed on the vertical plate 11 along the height direction.

[0019] Please see Figures 1-3As shown, two sets of waterproof motors 7 are installed on the top of the housing 1. The output shafts of the two sets of waterproof motors 7 are respectively connected to two sets of rotating shafts 15. The upper and lower sides of the rotating shafts 15 are rotatably connected to the inside of the housing 1. The waterproof motors 7 are the core power source of the device. Their output shafts can directly drive the rotating shafts 15 to rotate, providing power for the brushing action of the brush rollers 2 and the subsequent oscillating rinsing of the nozzles 5. The rotatable connection design between the rotating shafts 15 and the housing 1 can ensure the stable rotation of the rotating shafts 15 and avoid deviation during operation. At the same time, the waterproof motors 7 can adapt to the water vapor in the cleaning environment and are not easily damaged by water vapor.

[0020] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 As shown, two sets of side fixing blocks 13 are fixedly installed on both sides of the housing 1. The linkage rod 8 is slidably connected to the side fixing blocks 13 and the housing 1. The side fixing blocks 13 guide the linkage rod 8, ensuring that the linkage rod 8 only moves back and forth in a straight line, avoiding swaying or deviation during the movement. The sliding connection between the linkage rod 8 and the housing 1 further improves the movement stability, ensuring that the power transmitted by the cam 14 through the movable connecting rod 16 can be efficiently converted into the swinging power of the water pipe 3. The transmission components such as the cam 14, linkage rod 8, and movable connecting rod 16 can be made of stainless steel, and their surfaces can be coated with an anti-rust coating to achieve double protection and improve the waterproof and corrosion-resistant properties of the transmission components.

[0021] Please see Figures 1-3 As shown, the outer ring 4 is fixedly connected to the box body 1 by a connecting rod, and the diameters at the top and bottom ends of the water pipe 3 are smaller than the diameter at the middle.

[0022] Please see Figures 1-3 As shown, a base 6 is installed below the box body 1, and the lower end of the upright plate 11 is fixedly connected to the base 6.

[0023] Please see Figure 1 , Figure 2 as well as Figure 4 As shown, the fixed part of the rotary joint 18 is fixedly connected to the top of the water pipe 3, and its rotating part is connected to the water inlet pipe 9. The water inlet pipe 9 is fixedly connected to the housing 1 through the fixing rod. The rear end of the water inlet pipe 9 is connected to the pump pipe 10. The pump pipe 10 can deliver external water to the water inlet pipe 9. When the water pipe 3 reciprocates, the rotary joint 18 can achieve a sealed connection between the fixed water inlet pipe 9 and the rotating water pipe 3, which ensures that the water flow is stably delivered to the water pipe 3 and the nozzle 5, and does not affect the swinging action of the water pipe 3.

[0024] Please see Figures 1-3 As shown, a set of filter plates are installed at the air inlet and air outlet of the DC fan 12. Multiple sets of through holes are opened on the surface of the filter plate. The design of the through holes on the surface of the filter plate can block the impurities mixed in the air and prevent them from entering the DC fan 12 to avoid wear of the fan impeller.

[0025] In practical use, the working principle of this utility model is as follows: This device can be placed beside the track and washed when the locomotive slowly passes by. One set of the device can be placed on each side of the locomotive. When the locomotive passes by, the DC fan 12 is activated. Its inlet and outlet filter plates filter impurities in the airflow, creating an airflow that blows onto the locomotive surface, preemptively removing most of the floating dust, sand, and other debris adhering to the locomotive body. Two sets of water pump pipes 10 can be connected to an external water pump beforehand, transmitting the cleaning liquid through the water pump pipes 10 and inlet pipe 9 to the vertical water pipe 3, where it is sprayed out through the nozzle 5. Two sets of waterproof motors 7 are activated, their output shafts driving the rotation of the brush roller 2. The cams 14 connected to their upper and lower ends rotate together with the rotating shaft 15. The cams 14 convert the circular motion into the linear reciprocating motion of the linkage rod 8 via the movable connecting rod 16, which interacts with the side blocks on both sides of the housing 1. The linkage rod 8, which is slidably connected to the housing 13, drives the swing rods 17 at both ends of the vertical water pipe 3 to move synchronously through the connecting shaft. This causes the vertical water pipe 3, which is sleeved in the outer ring 4, to rotate back and forth within the outer ring 4. This causes multiple sets of nozzles 5 to swing and form a dynamic washing trajectory. When the locomotive continues to travel, the body is first washed by the nozzles 5 on the side closest to the DC fan 12. Then, the rotation of the brush roller 2 brushes the body. After brushing, the body is washed by the nozzles 5 on the other side, achieving efficient cleaning of the locomotive and effectively removing stubborn stains such as oil and carbon deposits. The direction of the swinging wash not only expands the washing range but also avoids excessive water flow impacting the same area, ultimately completing the rapid cleaning of the locomotive.
