Description

Technical Field

[0001] This application relates to cleaning equipment technology, and more particularly to a cleaning brush and a cleaning device for rail vehicles. Background Technology

[0002] Cleaning equipment used for cleaning rail vehicles typically involves making a brush contact with the surface of the vehicle and spraying water onto the brush, or at the point where the brush contacts the vehicle, the brush rotates and rubs against the vehicle surface to clean the vehicle.

[0003] During this process, the rotation of the brush generates a large centrifugal force, causing water to splash in all directions. This wastewater can easily splash onto other areas of the cleaning equipment, causing corrosion, and may also splash onto areas of the vehicle that have already been cleaned, affecting the cleaning effect. Utility Model Content

[0004] This application provides a cleaning brush and a cleaning device for rail vehicles to solve the problem that existing brushes cause water to splash in all directions when rotating.

[0005] On one hand, this application provides a cleaning brush, comprising:

[0006] support;

[0007] A brush body, which is movably mounted on the bracket, is provided with a flexible cleaning element for contacting the object to be cleaned;

[0008] A drive assembly, disposed on the bracket, is configured to drive the brush body to oscillate relative to the bracket so that the flexible cleaning element contacts different parts of the object to be cleaned.

[0009] In some possible implementations, the brush body is spaced apart from the bracket, and the brush body is further provided with a first connector, the end of the first connector opposite to the brush body being rotatably connected to the bracket.

[0010] In some possible implementations, the first connector is provided at both ends of the brush body.

[0011] In some possible implementations, the drive assembly includes a drive member and a second connector, one end of the second connector being rotatably connected to the output end of the drive member, and the other end being rotatably connected to the brush body or the first connector;

[0012] The drive member is configured to drive the second connector to move, so that the first connector is driven by the second connector to swing about the connection point between the first connector and the bracket.

[0013] In some possible implementations, the second connector is rotatably connected to a rotating wheel at the end opposite to the brush body, and the output end of the drive member is connected to the rotating wheel and drives the rotating wheel to rotate.

[0014] In some possible implementations, the connection point between the second connector and the wheel is eccentrically positioned relative to the central axis of the wheel.

[0015] In some possible implementations, the brush body is provided with a swing arm, and the second connector is rotatably connected to the end of the swing arm away from the brush body. The swing arm is configured such that, when the second connector moves, it is driven by the second connector to cause the first connector to swing around the connection point between the first connector and the bracket.

[0016] In some possible implementations, the brush body is arranged in an elongated shape.

[0017] In some possible implementations, the brush body oscillates along the width direction of the brush body.

[0018] In some possible implementations, the extension direction of the support is the same as the extension direction of the brush body.

[0019] In some possible implementations, the flexible cleaning element includes multiple flexible bristles.

[0020] In some possible implementations, the flexible bristles have a contact portion at the end that contacts the object to be cleaned, and the width of the contact portion gradually decreases along the direction away from the brush body.

[0021] In some possible implementations, the object to be cleaned that comes into contact with the flexible cleaning element is a rail vehicle.

[0022] On the other hand, this application provides a cleaning device for rail vehicles, including a device body and a cleaning brush as described in any one of the first aspects, the cleaning brush being disposed on the device body.

[0023] The cleaning brush and rail vehicle cleaning equipment provided in this application include a cleaning brush with a support, a brush body, and a drive assembly. The drive assembly drives the brush body to oscillate back and forth relative to the support, allowing the flexible cleaning elements on the brush body to contact different parts of the object to be cleaned. The object is cleaned through friction between the flexible cleaning elements and the object. Compared to traditional brush rotation, the brush body and flexible cleaning elements only oscillate without high-speed rotation, thus avoiding excessive water splashing in all directions during cleaning. Furthermore, the brush body can oscillate within a certain range, allowing it to cover a larger area of ​​the object to be cleaned, which helps reduce the space occupied by the brush. Therefore, by rationally arranging the cleaning brush on the main body of the cleaning equipment, the size and space occupied by the cleaning equipment can be effectively reduced.

[0045] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] As mentioned in the background section, when the brush of the cleaning equipment rotates to clean, it generates a large centrifugal force, causing a large amount of wastewater to splash. Furthermore, the direction of water splashing during rotation is uncontrollable and occurs in all directions.

[0048] Taking cleaning equipment for rail vehicles as an example, it typically includes components such as a frame structure, track system, water spray system, brush system, drying system, and control system. The frame structure supports other components and is usually made of metal to ensure the overall stability of the cleaning equipment and withstand the various forces generated during the washing process. The track system guides the vehicle to various cleaning stages, such as brushing and drying. Of course, some cleaning equipment may not have this component, allowing the vehicle to remain stationary while other components move to clean it. The water spray system generally includes a high-pressure water pump, nozzles, and pipes, primarily used to spray water or cleaning agents onto the vehicle surface, such as the contact points between the brushes and the vehicle surface. The nozzles may also have adjustable spray angles and water pressures to ensure the sprayed liquid covers the vehicle. The brush system generally includes multiple brushes that use rotating brushes or rolling brushes to scrub the vehicle surface. The number of brushes can be adjusted according to the actual design of the cleaning equipment. A drying system typically includes multiple fans or blowers to dry the vehicle's surface and prevent water stains. This component is not essential and can be selected based on actual needs. The control system usually includes a control panel and various sensors to control all components of the cleaning equipment, ensuring they work together to wash the vehicle. It can also adjust the shape or position of each component to suit different types of vehicles.

[0049] During the car wash process, the rotating brushes generate a large centrifugal force, causing wastewater to splash onto other parts such as the frame structure or areas of the vehicle that have already been washed. If the wastewater splashes onto other parts such as the frame structure, it will affect the corrosion resistance of these parts and make them more susceptible to mold growth. If the wastewater splashes onto areas of the vehicle that have already been cleaned, it will affect the cleaning effect.

[0050] The common solution is to make a water barrier to block the water, but water barriers need to be custom-made, which is costly.

[0051] Some cleaning equipment used for rail vehicles also uses roller brushes for cleaning. Although the direction of water splashing during use is controllable, the roller brush is relatively large, with a diameter of 800-1400mm after the bristles are spread out. Cleaning equipment used for rail vehicles generally needs to be arranged with top brushes and side brushes, staggered to avoid mutual interference. This results in the cleaning equipment being relatively large and requiring a lot of space.

[0052] In response, this application provides a cleaning brush. The brush body can oscillate back and forth relative to the support under the drive of the drive component, so that when the flexible cleaning element on the brush body cleans the object to be cleaned, the wastewater will not splash everywhere. This avoids the problem of wastewater splashing in all directions when using a traditional rotary brush. At the same time, compared with a traditional roller brush, the cleaning brush only needs to set the flexible cleaning element on the side facing the object to be cleaned, so that the volume of the cleaning brush can be reduced to about one-fifth of that of a traditional roller brush. Therefore, when the cleaning brush is applied to cleaning equipment, the overall volume of the cleaning equipment can be reduced by reasonably arranging the cleaning brush, so as to effectively reduce the space occupied by the cleaning equipment.

[0053] It should be noted that the cleaning brush in this application embodiment can be applied not only to cleaning equipment, but also to other equipment with similar cleaning needs during use, and this application does not impose any restrictions on it.

[0054] Meanwhile, the cleaning brush in this application embodiment can be applied not only to cleaning equipment for cleaning rail vehicles, but also to other equipment with similar cleaning needs or cleaning equipment for non-rail vehicles. However, for ease of understanding, this application will use cleaning equipment for cleaning rail vehicles as an example for explanation.

[0055] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0056] In some embodiments, see Figure 1 As shown, the cleaning brush includes a bracket 100, a brush body 200, and a drive assembly 300.

[0057] The bracket 100 is used to connect with the main body of the cleaning equipment, such as a frame. The brush body 200 is movably mounted on the bracket 100. The brush body 200 is provided with a flexible cleaning element 210, which is used to contact the surface of the object to be cleaned and clean the surface of the object. The drive component 300 is mounted on the bracket 100 and drives the brush body 200 to swing relative to the bracket 100, so that the flexible cleaning element 210 on the brush body 200 contacts different parts of the object to be cleaned, thereby increasing the area of ​​the object to be cleaned that can be cleaned by the flexible cleaning element 210. The object to be cleaned can be a rail vehicle or other equipment. The following description will use a rail vehicle as an example.

[0058] It should be noted that during the swinging process driven by the drive component 300, the flexible cleaning component 210 needs to always be in contact with the surface of the vehicle to be cleaned. Therefore, the flexible cleaning component 210 may deform more in some areas due to the pressure of the vehicle surface, and less in some areas, in order to ensure that it is always in contact with the vehicle surface.

[0059] Correspondingly, the flexible cleaning component 210 is made of flexible materials, such as fiber materials and foam cotton, which can flexibly rub against the vehicle surface when in contact with it to clean the vehicle surface without scratching the vehicle's paint.

[0060] For example, please see Figure 1 and Figure 2 As shown, the flexible cleaning component 210 includes multiple flexible bristles, which are fixed on the brush body 200. The flexible bristles can be fixed on the brush body 200 in a certain pattern or randomly, as long as they can effectively clean the stains on the vehicle surface during the cleaning process.

[0061] For example, flexible materials such as wool, microfiber, sponge, and synthetic fiber can be made into strips and fixed to the brush body 200 by common methods such as adhesive.

[0062] It should be noted that the flexible cleaning component can also be a structure of other shapes made of the aforementioned flexible material, as long as it can effectively clean the vehicle.

[0063] In order to facilitate close contact between the flexible bristles and the object to be cleaned during cleaning, the end of the flexible bristles that contacts the object to be cleaned has a contact portion 211, and the width of the contact portion 211 gradually decreases along the direction away from the brush body 200.

[0064] For example, the flexible bristles can be rectangular columnar at the end that contacts the brush body 200, with the contact portion 211 located at the end of the rectangular column that is away from the brush body 200, and its width gradually decreases along the direction away from the brush body 200, forming a trapezoidal structure.

[0065] The bracket 100 mainly supports the brush body 200 and the drive assembly 300. It needs to have a certain strength and can be made of shaped steel or ordinary steel plate. It can be any shape, as long as it can support the brush body 200 and the drive assembly 300 and is easy to connect to the frame structure of the main body of the equipment.

[0066] The brush body 200 needs to withstand the force applied by the drive component 300 to swing relative to the bracket 100, so it also needs to have a certain rigidity. It can be steel or other composite materials that can be adapted to the usage requirements. This embodiment does not limit it.

[0067] During use, the brush body 200 is driven by the drive component 300 to swing the brush bristles to clean the vehicle. Compared with traditional rotary brushes, the swing range of the brush body 200 is controlled by the drive component 300 and is generally not too large. Therefore, it will not cause a lot of sewage to splash everywhere, thus avoiding water corrosion of the frame structure or the accumulation and growth of mold on the frame structure during the car wash process. It can also prevent sewage from splashing onto the parts of the vehicle that have already been cleaned, thus affecting the cleaning effect.

[0068] Meanwhile, compared to traditional roller brushes, the brush body 200 does not need to be cylindrical and have bristles on all sides. It only needs to be set as a relatively narrow strip. Driven by the drive component 300 to swing, it can cover a larger area. That is, its volume can be reduced to about one-fifth of that of a traditional roller brush, while still covering a larger cleaning area, saving space and providing a larger cleaning range.

[0069] In some embodiments, see Figure 3 and Figure 4 As shown, in order to allow the brush body 200 to swing a slightly larger range and not interfere with the bracket 100, the brush body 200 and the bracket 100 can be spaced apart to maintain a certain distance between them. The brush body 200 is also provided with a first connector 220. One end of the first connector 220 is connected to the brush body 200 by welding, bolting, or integral molding, while the other end is rotatably connected to the bracket 100. For example, the first connector 220 and the bracket 100 can be connected by common hinge connections, shaft connections, etc.

[0070] The length of the first connector 220 between the bracket 100 and the brush body 200 is the length of the swing arm 230 corresponding to the brush body 200. By adjusting the length of the first connector 220, the cleaning range that the flexible cleaning part can cover can be changed when the brush body 200 rotates by the same angle.

[0071] Furthermore, second connectors 320 can be provided at both ends of the brush body 200 to improve the connection between the brush body 200 and the bracket 100.

[0072] For example, please see Figure 8 As shown, two sets of connecting ears 110 are provided on the bracket 100. Each set of connecting ears 110 includes two opposing connecting ears 110. A connecting rod is provided at each end of the brush body 200. The second connecting member 320 is a connecting plate, one end of which is fixedly connected to the connecting rod, and the other end extends to the space between the two connecting ears 110 of the set of connecting ears 110. The connecting plate and the connecting ears 110 are connected by a hinge shaft, so that the connecting plate can rotate around the hinge shaft.

[0073] It should be noted that one or more second connectors 320 can be provided, and the specific number can be adjusted according to the support requirements of the brush body 200. This embodiment does not limit this.

[0074] In some embodiments, the brush body 200 may be arranged in a strip shape to adapt to the top or side wall structure of the rail vehicle and to increase the cleaning area of ​​the brush body 200.

[0075] Furthermore, the extension direction of the bracket 100 and the brush body 200 can be the same. In this case, if multiple first connectors 220 are provided, the first connectors 220 can be arranged sequentially along the extension direction of the brush body 200. The drive assembly 300 drives the brush body 200 to swing along the width direction of the bracket 100, that is, the brush body 200 swings along the width direction of the brush body 200.

[0076] This configuration ensures that the length and width of the bracket 100 and the brush body 200 are not too different, which reduces the overall space occupied by the cleaning brush. At the same time, it also makes it easier to connect the bracket 100 and the brush body 200.

[0077] In some embodiments, see Figure 5 and Figure 6 As shown, the drive assembly 300 includes a drive member 310 and a second connector 320. The two ends of the second connector 320 are rotatably connected to the brush body 200 and the output end of the drive member 310, respectively.

[0078] During use, the drive component 310 drives the second connector 320 to move, and the second connector 320 drives the first connector 220 to swing around the connection point between the bracket 100 and the first connector 220, thereby causing the brush body 200 to swing, so that the flexible cleaning component 210 can swing within a preset range to clean the corresponding area of ​​the vehicle.

[0079] The specific implementation methods of the driving component 310 and the second connecting component 320 include, but are not limited to, the following two:

[0080] For example, the drive component 310 is a combination of a motor and a reciprocating lead screw. The motor drives the reciprocating lead screw to rotate. A connecting seat is provided on the reciprocating lead screw, and a guide rod parallel to the reciprocating lead screw can be provided. The connecting seat and the guide rod are slidably connected. The guide rod restricts the movement of the connecting seat, causing it to reciprocate along the length direction of the reciprocating lead screw when it rotates. The second connecting component 320 is a connecting rod or a connecting plate. Both ends of the second connecting component 320 are rotatably connected to the brush body 200 and the connecting seat, respectively. When the motor drives the reciprocating lead screw to rotate, the connecting seat drives the end of the second connecting component 320 connected to the connecting seat to reciprocate along the extension direction of the reciprocating lead screw, thereby causing the second connecting component 320 to drive the brush body 200 to swing within a preset range. The swing angle range of the brush body 200 can be limited by the thread length of the reciprocating lead screw.

[0081] For example, the driving component 310 is a motor, and the second connecting component 320 includes a connecting rod and a rotating wheel 330. The end of the connecting rod away from the brush body 200 is rotatably connected to the rotating wheel 330. The output end of the driving component 310 is connected to the rotating wheel 330 and drives the rotating wheel 330 to rotate. The connection point between the driving component 310 and the rotating wheel 330 is offset from the connection point between the connecting rod and the rotating wheel 330. It can be understood that the rotating wheel 330 is coaxially arranged with the output shaft of the motor, and the connection point between the connecting rod and the rotating wheel 330 is eccentrically arranged relative to the central axis of the rotating wheel 330. When the motor drives the rotating wheel 330 to rotate, it will drive the connecting rod to move periodically, thereby driving the brush body 200 to oscillate back and forth within a preset range through the connecting rod.

[0082] The bracket 100 can be configured as a rectangular column, the brush body 200 is connected to one side of the bracket 100, and the drive component 310 is fixed on the other side of the bracket 100 adjacent to that side. Correspondingly, the brush body 200 can also be configured as a rectangular column, but its length, width and height are slightly smaller than the bracket 100. This makes installation convenient and avoids interference between the components.

[0083] It should be noted that the drive component 300 can also be other common structures that can drive the brush body 200 to swing. This embodiment is only an example and not a limitation. For example, the drive component 300 can also be a combination of a motor and a cam. The cam is located on one side of the brush body 200. When the motor drives the cam to rotate, different positions of the cam contact the brush body 200, which can push the brush body 200 to swing.

[0084] In some embodiments, see Figure 6 and Figure 7 A swing arm 230 can also be provided on the brush body 200. The second connector 320 is connected to the brush body 200 through the swing arm 230. That is, one end of the swing arm 230 is fixedly connected to the brush body 200, and the other end is rotatably connected to the second connector 320.

[0085] Specifically, in practical applications, the first connector 220 may have a certain length, which creates a certain distance between the brush body 200 and the bracket 100. If the second connector 320 is too long, it may interfere with the brush body 200 during use. In this case, the swing arm 230 can be used to compensate for this by shortening the length of the second connector 320 and avoiding interference between the second connector 320 and the brush body 200 during movement.

[0086] This application also provides a cleaning device for rail vehicles. The cleaning device includes a main body and a cleaning brush as described in the above embodiments, with the cleaning brush disposed on the main body.

[0087] The main body of the equipment typically includes a frame structure, track system, drying system, and control system. The frame structure supports other components and is usually made of metal, capable of withstanding various forces generated during the car washing process.

[0088] The track system can guide the vehicle to various cleaning stages, such as scrubbing and drying. Of course, some cleaning equipment may not be equipped with this component, so that the vehicle remains stationary while other components move to clean the vehicle.

[0089] A water spray system generally includes a high-pressure water pump, nozzles, and pipes. It is mainly used to spray water or cleaning agents onto the surface of a vehicle, such as the position where the flexible cleaning component 210 contacts the surface of the vehicle. The nozzles can also have adjustable spray angles and adjustable water pressure so that the sprayed liquid can cover the vehicle.

[0090] A drying system typically includes multiple fans or blowers to dry the surface of a vehicle and prevent water stains from remaining. Of course, this component is not essential and can be selected for installation based on actual conditions.

[0091] The control system typically includes a control panel and various sensors to control all components of the cleaning equipment, enabling them to work together to clean the vehicle. It can also adjust the shape or position of each component to suit different types of vehicle cleaning.

[0092] The car wash machine also includes a brush system, which generally includes multiple cleaning brushes as described in the above embodiments, as well as other common brushes and cleaning brushes as described in the above embodiments. The cleaning brush bracket 100 is connected to the frame structure by common methods such as bolts or welding to fix it to the frame structure. To facilitate connection, flanges can be added to both ends of the bracket 100 to increase the contact area with the frame structure.

[0093] During assembly, brushes extending horizontally and vertically are typically installed on the top and side walls of the vehicle, respectively. By rationally allocating the positions of the cleaning brushes, the total number of cleaning brushes can be reduced, which in turn helps to reduce the overall volume of the car wash machine and thus reduce the space required by the car wash machine.

[0094] It should be noted that the structure and working principle of the cleaning brush have been described in the above embodiments, and will not be repeated here.

[0095] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.

[0096] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
