Description

Technical Field

[0001] This utility model belongs to the field of rail vehicle maintenance technology, and more specifically, it relates to a cleaning device for air conditioning vents of rail vehicles. Background Technology

[0002] Subway cars are crowded, and the air contains a large amount of pollutants such as dust, dander, and hair. During operation, these pollutants accumulate on the grille surface and internal structure of the air conditioning vents. If these vents are not cleaned regularly, they will be blown back into the car when the air conditioning is turned on again, reducing air quality and affecting passenger health.

[0003] When cleaning the air conditioning vents in the subway, staff need to first remove the vent grilles from the top of the carriage, and then use brushes to clean the contaminants adhering to the internal structure of the vents. However, since the vents are located on the top of the carriage, staff have to keep their arms raised high while cleaning, which is labor-intensive and inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a cleaning device for the air conditioning vents of rail vehicles, which is designed to facilitate the cleaning of the air conditioning vents of subways by staff.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a cleaning device for the air conditioning vents of rail vehicles, comprising:

[0006] Mobile platform;

[0007] The dust collection hood is lifted and mounted on the mobile platform;

[0008] A brush roller assembly is horizontally rotatably mounted at the top of the dust collection hood and extends from the top of the dust collection hood; the brush roller assembly is driven by a rotation drive assembly so that when the outer peripheral surface of the brush roller assembly contacts the internal structure of the air outlet, the brush roller assembly rotates to clean the internal structure of the air outlet; and

[0009] An operating handle is provided on the mobile platform and connected to the dust collection hood via a reaction force component, so that when the operator presses down on the operating handle, the dust collection hood rises up and extends into the air outlet.

[0010] In one possible implementation, the reaction force component includes:

[0011] The first rack is vertically slidably mounted on the moving platform and is fixedly connected to the dust collection hood;

[0012] The second rack is vertically slidably mounted on the moving platform and is fixedly connected to the operating handle;

[0013] A linkage gear is rotatably mounted on the moving platform and meshes simultaneously with the first rack and the second rack, with the linkage gear located between the first rack and the second rack.

[0014] In one possible implementation, the reaction force component includes:

[0015] The first connecting column is vertically slidably disposed on the moving platform and is fixedly connected to the dust collection hood;

[0016] The second connecting post is vertically slidably disposed on the moving platform and is fixedly connected to the operating handle;

[0017] A fixed pulley is rotatably mounted on the moving platform;

[0018] The bottom end of the first connecting column and the top end of the second connecting column are connected by a connecting rope, which is wound around the fixed pulley.

[0019] In one possible implementation, the brush roller assembly includes two cleaning brushes arranged side by side, the cleaning brushes being rotatably connected to the dust collection hood, with a gap formed between the two cleaning brushes to allow contaminants to pass through.

[0020] In one possible implementation, the two cleaning brushes rotate toward each other.

[0021] In one possible implementation, the rotation drive assembly includes:

[0022] The motor is fixedly mounted on the dust collection hood, and a first synchronous pulley is fixedly mounted on the output shaft;

[0023] The second synchronous pulley is fixedly mounted on any of the cleaning brushes and is connected to the first synchronous pulley via a first synchronous belt;

[0024] The third synchronous pulley is coaxially fixed on the second synchronous pulley;

[0025] The fourth synchronous pulley is rotatably mounted on the dust collection hood and is connected to the third synchronous pulley via a second synchronous belt;

[0026] The driving gear is coaxially fixed on the fourth synchronous pulley;

[0027] The driven gear is fixedly mounted on another cleaning brush and meshes with the driving gear.

[0028] In one possible implementation, two comb teeth are fixedly provided on the inner wall of the dust collection hood. The comb teeth are located below the cleaning brush and correspond one-to-one with the cleaning brush. The comb teeth extend into the bristles of the cleaning brush so that when the cleaning brush rotates, the comb teeth clean the adhering substances on the bristles.

[0029] In one possible implementation, a damping rod is fixedly disposed between the dust collection hood and the mobile platform.

[0030] In one possible implementation, the lower end of the dust collection hood is connected to a vacuum cleaner via a suction pipe, and the vacuum cleaner is fixedly mounted on the mobile platform.

[0031] In one possible implementation, the dust collection hood has a flared top and a constricted bottom.

[0032] This utility model provides a cleaning device for air conditioning vents in rail vehicles. Compared with existing technologies, its advantages are as follows: Initially, the dust collection hood is positioned low on the moving platform, allowing workers to freely adjust the platform's position so that the hood is below the vent. When the hood needs to be inserted into the vent, pressing down on the operating handle uses a reaction force component to lift the hood into the vent. This process eliminates the need for prolonged arm extension, significantly reducing arm strain and labor intensity, allowing workers to perform cleaning tasks more easily. The brush roller assembly is driven by a rotation drive component. After the hood enters the vent, the outer surface of the brush roller assembly makes full contact with the vent's internal structure. Driven by the rotation drive component, the brush roller assembly rotates at high speed, thoroughly cleaning the vent's internal structure. The brushed-off contaminants are less likely to spread under the hood's cover, with most falling directly into the hood. This avoids the cumbersome steps of separate collection and treatment of contaminants after cleaning, as required by traditional methods, reducing secondary pollution and improving the overall efficiency and quality of cleaning work.

[0040] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0041] Please see Figure 1 This invention provides a cleaning device for air conditioning vents in rail vehicles. The device includes a mobile platform 1, a dust collection hood 2, a brush roller assembly 3, and an operating handle 4. The dust collection hood 2 is vertically mounted on the mobile platform 1. The brush roller assembly 3 is horizontally rotatably mounted at the top of the dust collection hood 2 and extends from the top. The brush roller assembly 3 is driven by a rotation drive assembly, so that when the outer circumferential surface of the brush roller assembly 3 contacts the internal structure of the vent, the brush roller assembly 3 rotates to clean the internal structure of the vent. The operating handle 4 is mounted on the mobile platform 1 and connected to the dust collection hood 2 via a reaction force assembly, so that when the operator presses down on the operating handle 4, the dust collection hood 2 rises and extends into the vent.

[0042] Specifically, in the initial state, the dust collection hood 2 is positioned low on the mobile platform 1, allowing the operator to naturally grip the operating handle 4. When it is necessary to extend the dust collection hood 2 into the air outlet, the operator presses down on the operating handle 4, and the reaction force component causes the dust collection hood 2 to rise and enter the air outlet. During this process, the arm does not need to be held in a raised position for a long time, greatly reducing the burden on the arm and lowering the labor intensity, allowing the operator to perform cleaning work more easily. After the dust collection hood 2 is extended into the air outlet, the outer circumference of the brush roller assembly 3 can fully contact the internal structure of the air outlet. Driven by the rotation drive component, the brush roller assembly 3 rotates at high speed, thoroughly cleaning the internal structure of the air outlet. Compared with the traditional method of manual brush cleaning, this reduces the physical exertion of repeatedly raising the hand and brushing forcefully, making the cleaning work easier and more convenient, improving work efficiency, and reducing operator fatigue.

[0043] In some embodiments, see Figure 2 The reaction force assembly includes a first rack 51, a second rack 52, and a linkage gear 53. The first rack 51 is vertically slidably mounted on the moving platform 1 and is fixedly connected to the dust collection hood 2. The second rack 52 is vertically slidably mounted on the moving platform 1 and is fixedly connected to the operating handle 4. The linkage gear 53 is rotatably mounted on the moving platform 1 and meshes with both the first rack 51 and the second rack 52 simultaneously. The linkage gear 53 is located between the first rack 51 and the second rack 52.

[0044] When the operator presses down on the operating handle 4, the second rack 52 moves downward, and through the transmission of the linkage gear 53, the first rack 51 moves upward, thereby causing the dust collection hood 2 to rise. This rack and pinion transmission method has high precision and stability, and can accurately control the lifting height and speed of the dust collection hood 2. In the environment where the space on the top of the subway car is limited and the air outlet position is relatively fixed, it avoids problems such as collisions or inaccurate docking with the air outlet caused by improper lifting of the dust collection hood 2, improves the convenience and accuracy of operation, and ensures the smooth progress of cleaning work.

[0045] In some embodiments, see Figure 3 The reaction assembly includes a first connecting column 54, a second connecting column 55, and a fixed pulley 56. The first connecting column 54 is vertically slidably mounted on the moving platform 1 and is fixedly connected to the dust collection hood 2. The second connecting column 55 is vertically slidably mounted on the moving platform 1 and is fixedly connected to the operating handle 4. The fixed pulley 56 is rotatably mounted on the moving platform 1. The bottom end of the first connecting column 54 and the top end of the second connecting column 55 are connected by a connecting rope 57, which is wound around the fixed pulley 56.

[0046] When the operator presses down the operating handle 4, the second connecting column 55 moves downward, and through the action of the connecting rope 57 and the fixed pulley 56, the first connecting column 54 moves upward, thereby causing the dust collection hood 2 to rise. In actual use, the linkage between the dust collection hood 2 and the operating handle 4 ensures that the dust collection hood 2 can be raised and lowered according to the operator's intention, improving the stability and reliability of the cleaning device.

[0047] In some embodiments, see Figure 4 The brush roller assembly 3 includes two cleaning brushes 31 arranged side by side. The cleaning brushes 31 are rotatably connected to the dust collection hood 2, and a gap is formed between the two cleaning brushes 31 to allow pollutants to pass through.

[0048] When the dust collection hood 2 extends into the air outlet, the two cleaning brushes 31 can simultaneously clean different parts of the internal structure of the air outlet, greatly increasing the contact area and cleaning range with contaminants and improving cleaning efficiency. Furthermore, contaminants can fall through the gap between the two cleaning brushes 31, preventing excessive accumulation on the brushes and ensuring a more continuous and efficient cleaning process, thus more thoroughly removing dust, dander, hair, and other contaminants adsorbed on the internal structure of the air outlet.

[0049] In some embodiments, the two cleaning brushes 31 rotate in opposite directions, causing the bristles of the two cleaning brushes 31 to generate a relative pulling force and friction when they come into contact with contaminants. This more effectively removes stubborn contaminants adsorbed on the internal structure of the air outlet. Simultaneously, the opposite rotation also helps to squeeze the cleaned contaminants towards the center and discharge them downwards through the gap between the two cleaning brushes 31, preventing contaminants from remaining and accumulating on the cleaning brushes 31. This further improves the cleaning effect, allowing for a more thorough cleaning of the internal structure of the air outlet and ensuring air quality when the air conditioner outlet resumes operation.

[0050] In some embodiments, see Figure 4 and Figure 5 The rotation drive assembly includes a motor 61, a second synchronous pulley 63, a third synchronous pulley 65, a fourth synchronous pulley 66, a drive gear 68, and a driven gear 69. The motor 61 is fixedly mounted on the dust collection hood 2, and a first synchronous pulley 62 is fixedly mounted on its output shaft. The second synchronous pulley 63 is fixedly mounted on any of the cleaning brushes 31 and connected to the first synchronous pulley 62 via a first synchronous belt 64. The third synchronous pulley 65 is coaxially fixedly mounted on the second synchronous pulley 63. The fourth synchronous pulley 66 is rotatably mounted on the dust collection hood 2 and connected to the third synchronous pulley 65 via a second synchronous belt 67. The drive gear 68 is coaxially fixedly mounted on the fourth synchronous pulley 66. The driven gear 69 is fixedly mounted on another cleaning brush 31 and meshes with the drive gear 68.

[0051] The first synchronous pulley 62 on the output shaft of motor 61 is connected to the second synchronous pulley 63 fixed on either cleaning brush 31 via the first synchronous belt 64, thus realizing the initial transmission of power. Then, the third synchronous pulley 65, coaxially fixed on the second synchronous pulley 63, is connected to the fourth synchronous pulley 66 rotatably mounted on the dust collection hood 2 via the second synchronous belt 67. The driving gear 68 on the fourth synchronous pulley 66 meshes with the driven gear 69 fixed on another cleaning brush 31, thereby realizing the opposite rotation of the two cleaning brushes 31.

[0052] In some embodiments, see Figure 4 Two comb teeth 21 are fixedly installed on the inner wall of the dust collection cover 2. The comb teeth 21 are located below the cleaning brush 31 and correspond one-to-one with the cleaning brush 31. The comb teeth 21 extend into the bristles of the cleaning brush 31 so that when the cleaning brush 31 rotates, the comb teeth 21 clean the adhering substances on the bristles.

[0053] During the cleaning process, as the cleaning brush 31 continuously sweeps the internal structure of the air outlet, dust, dander, hair, and other contaminants gradually adhere to the bristles. If not cleaned in time, this will reduce the cleaning effect of the cleaning brush 31. The comb teeth 21, however, can scrape off these contaminants from the bristles without affecting the normal rotation of the cleaning brush 31, ensuring that the cleaning brush 31 maintains good cleaning ability and can continuously and effectively clean the internal structure of the air outlet. This improves the overall cleaning effect and efficiency of the cleaning device and extends the service life of the cleaning brush 31.

[0054] In some embodiments, see Figure 1 A damping rod 7 is fixedly installed between the dust collection hood 2 and the moving platform 1. When the operator controls the dust collection hood 2 to rise or fall using the operating handle 4, the damping rod 7 provides a certain amount of damping, making the raising and lowering process of the dust collection hood 2 more stable and avoiding shaking or instability of the dust collection hood 2 due to excessive raising and lowering speed or external interference. At the same time, the damping rod 7 can buffer the impact force of the dust collection hood 2 during the raising and lowering process, reducing the risk of damage to components such as the dust collection hood 2, brush roller group 3, and moving platform 1 due to collisions or severe vibrations.

[0055] In some embodiments, see Figure 1 The lower end of the dust collection hood 2 is connected to a vacuum cleaner 92 via a suction pipe 91, and the vacuum cleaner 92 is fixedly mounted on the moving platform 1. During the cleaning process, when the brush roller assembly 3 cleans the internal structure of the air outlet, the pollutants brushed off will fall directly into the dust collection hood 2 under its cover. The vacuum cleaner 92 can further suck away the pollutants inside the dust collection hood 2 through the suction pipe 91, which greatly improves the cleaning device's ability to collect pollutants and can more thoroughly remove dust, dander, hair and other pollutants from the internal structure of the air outlet, preventing pollutants from remaining in the dust collection hood 2 or being scattered back into the carriage.

[0056] In some embodiments, see Figure 1 The dust collection hood 2 has a flared top and a constricted bottom. The flared top makes it easier for the dust collection hood 2 to align with and cover the air outlet, increasing the inlet area of ​​the dust collection hood 2 and facilitating the collection of pollutants swept down from the internal structure of the air outlet. After the pollutants are swept down by the brush roller assembly 3, they are more likely to enter the dust collection hood 2, reducing the possibility of pollutants scattering into the vehicle compartment. The constricted bottom of the dust collection hood 2 helps guide pollutants to concentrate at the bottom of the dust collection hood 2, making it easier for the vacuum cleaner 92 to collect them for subsequent processing.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
