Description

Technical Field

[0001] This application relates to the field of logistics technology, and in particular to cleaning facilities and rail-guided vehicles. Background Technology

[0002] New energy batteries are being used more and more widely in daily life and industry. For example, new energy vehicles equipped with batteries are already widely used. In addition, batteries are being used more and more in the field of energy storage.

[0003] Rail-guided vehicles are widely used in battery production and logistics. They run along guide rails to carry and transport goods. In the operation of rail-guided vehicles, the guide rails are often not thoroughly cleaned. Therefore, how to reduce the blind spots in the cleaning of the guide rails and improve the cleaning effect of the guide rails is one of the research and development topics in the industry. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a cleaning mechanism and a rail-guided vehicle.

[0005] This application is achieved through the following technical solution.

[0006] The first aspect of this application discloses a cleaning mechanism applicable to a rail-guided vehicle. The rail-guided vehicle travels along a guide rail in a first direction. The cleaning mechanism is disposed on at least one side of the rail-guided vehicle, and the first direction is the forward and backward direction of the rail-guided vehicle. The cleaning mechanism has a first cleaning surface and a second cleaning surface. The first cleaning surface is configured to be in contact with the upper surface of the guide rail. The second cleaning surface is disposed on at least one side of the guide rail along a second direction and is configured to be in contact with the guide rail along the second direction. The second direction is perpendicular to the first direction and the direction of gravity.

[0007] Because a cleaning mechanism is installed in the forward and backward directions of the rail-guided vehicle, and the first and second cleaning surfaces of the cleaning mechanism can adhere to the surface of the guide rail, the cleaning mechanism can move along the guide rail with the rail-guided vehicle, facilitating comprehensive cleaning of the guide rail and reducing the workload of regular cleaning. Furthermore, multiple cleaning surfaces can form a three-dimensional cleaning effect, fully covering the working surface of the guide rail, reducing blind spots, extending the service life of the guide rail, and supporting the normal operation of the rail-guided vehicle.

[0008] In some embodiments, the cleaning mechanism includes a mounting frame, a first cleaning block, and at least one second cleaning block. The mounting frame is connected to the rail-guided vehicle, and the first cleaning block and the second cleaning block are respectively connected to the mounting frame. The first cleaning block has a first cleaning surface and is configured to be disposed on the upper side of the guide rail. The second cleaning block has a second cleaning surface and is configured to be disposed on at least one side of the guide rail along the second direction.

[0009] As a result, multiple cleaning blocks are connected to the mounting bracket. The cleaning surface of the cleaning block is more likely to fit the guide rail surface, which is conducive to modular design. The cleaning block and cleaning surface can be replaced in different cleaning scenarios to adapt to various cleaning needs.

[0010] In some embodiments, the first cleaning block has a cavity inside, and the cavity is provided with a spring in a compressed state, the spring being configured to apply a force along the direction of gravity to the first cleaning surface; and / or, the second cleaning block has a cavity inside, and the cavity is provided with a spring inside, the cavity being provided with a spring in a compressed state, the spring being configured to apply a force along a second direction toward the guide rail to the second cleaning surface.

[0011] Therefore, the spring applies elastic force to the cleaning surface through the cavity, so that the cleaning block always sticks to the guide rail surface. When the cleaning mechanism moves with the rail-guided vehicle, the spring can automatically adjust the pressure according to the vibration, avoiding cleaning dead corners caused by poor local contact, and improving the dynamic adaptability and cleaning effect of the cleaning mechanism.

[0012] In some embodiments, the first cleaning block has a first surface on the side away from the rail-guided vehicle along the first direction, and the angle between the first surface and the first cleaning surface is an acute angle.

[0013] This improves the first cleaning block's ability to remove foreign objects from the guide rail surface to a certain extent, and cleans up adhesive foreign objects such as dried soil or clumps of mud and sand, further enhancing the cleaning effect.

[0014] In some embodiments, the angle between the first surface and the first cleaning surface is in the range of 40° to 60°.

[0015] This further enhances the first cleaning block's ability to remove foreign objects from the guide rail surface and improves its cleaning effect.

[0016] In some embodiments, the cleaning mechanism includes a first pad, the first cleaning block has a first groove on the side where the first cleaning surface is located, and the first pad is disposed in the first groove.

[0017] Therefore, a first groove is designed as a filling groove for the first gasket. The first gasket can fill the installation gap between the first cleaning block and the second cleaning block, preventing liquids, dust, or particles generated during the cleaning process from entering the installation gap between the cleaning block and the support structure, thus avoiding corrosion of the mounting bracket. Furthermore, by adjusting the thickness of the first gasket, the gap between the first cleaning block and the guide rail can be adjusted, which helps to improve the fit between the first cleaning block and the guide rail surface.

[0018] In some embodiments, the cleaning mechanism includes two second cleaning blocks and a second pad, the two second cleaning blocks being respectively disposed on both sides of the guide rail along the second direction; along the second direction, the second pad is disposed on the side of each second cleaning block away from the second cleaning surface, and the second pad is located between the mounting bracket and each second cleaning block.

[0019] Therefore, the shim can disperse the contact pressure between the second cleaning block and the mounting bracket, preventing localized stress concentration that could damage the second cleaning block or the mounting bracket. Furthermore, by adjusting the thickness of the second shim, the gap between the second cleaning block and the guide rail can be adjusted, which helps improve the fit between the second cleaning block and the guide rail surface.

[0020] In some embodiments, the mounting bracket is bolted to the rail-guided vehicle; the first cleaning block is bolted to the mounting bracket, and / or the second cleaning block is bolted to the mounting bracket.

[0021] Therefore, the bolted connection is simple and reliable, preventing the cleaning block from loosening or falling off during operation due to vibration, impact, or external force. It also facilitates the disassembly and maintenance of the cleaning block, and allows for better adjustment of its position.

[0022] In some embodiments, the mounting bracket includes a first plate and a second plate connected to each other, the first plate being perpendicular to the first direction, and the second plate being disposed on the side of the first plate away from the side where the rail-guided vehicle is located along the first direction; a first clearance portion is provided on the side of the first plate along the direction of gravity, the first clearance portion being used to avoid the guide rail; the first plate is connected to the first cleaning block, and the second plate is connected to the second cleaning block.

[0023] This facilitates the connection between the first cleaning block, the second cleaning block, and the mounting bracket. The first plate can connect to and support the first cleaning block, and the second plate can connect to and support the second cleaning block.

[0024] In some embodiments, the first cleaning block includes at least one of a nylon block, a polyoxymethylene resin block, and a foam block, and / or the second cleaning block includes at least one of a nylon block, a polyoxymethylene resin block, and a foam block.

[0025] Therefore, the cleaning block has good elasticity and wear resistance, and can effectively clean the guide rail surface through physical friction and adsorption, resulting in a long service life. In addition, the cleaning block also has a self-lubricating function, lubricating the guide rail while cleaning it.

[0026] The second aspect of this application discloses a rail-guided vehicle, which includes a vehicle body, at least one traveling mechanism connected to the vehicle body, and a plurality of cleaning mechanisms as described in the first aspect of this application, connected to the vehicle body. Along a first direction, the cleaning mechanisms are disposed on at least one side of the traveling mechanism.

[0027] The beneficial effects of the embodiments of this application include: the cleaning mechanism of this application is applicable to rail-guided vehicles, and the cleaning mechanism can be installed on the rail-guided vehicle. When the rail-guided vehicle is moving, the cleaning mechanism can perform a comprehensive cleaning of the guide rail, fully covering the working surface of the guide rail, reducing cleaning blind spots, improving the service life of the guide rail, and providing support for the normal operation of the rail-guided vehicle.

[0028] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0053] The following is a detailed description of this application.

[0054] New energy batteries are being used more and more widely in daily life and industry. For example, new energy vehicles equipped with batteries are already widely used. In addition, batteries are being used more and more in the field of energy storage.

[0055] Rail-guided vehicles are widely used in battery production and logistics. They run along guide rails to carry and transport goods. In the operation of rail-guided vehicles, the guide rails are often not thoroughly cleaned. Therefore, how to reduce the blind spots in the cleaning of the guide rails and improve the cleaning effect of the guide rails is one of the research and development topics in the industry.

[0056] After research and design, a cleaning mechanism was installed on the body of the rail-guided vehicle. The cleaning mechanism covers multiple surfaces of the rails and can clean each surface of the rails as the rail-guided vehicle moves.

[0057] Based on this design concept, this application designs a cleaning mechanism suitable for a rail-guided vehicle. The rail-guided vehicle travels along a guide rail. Along a first direction, the cleaning mechanism is disposed on at least one side of the rail-guided vehicle. The first direction is the forward and backward direction of the rail-guided vehicle. The cleaning mechanism has a first cleaning surface and a second cleaning surface. The first cleaning surface is configured to fit against the upper surface of the guide rail. The second cleaning surface is disposed on at least one side of the guide rail along a second direction and is configured to fit against the guide rail along the second direction. The second direction is perpendicular to the first direction and the direction of gravity.

[0058] Because a cleaning mechanism is installed in the forward and backward directions of the rail-guided vehicle, and the first and second cleaning surfaces of the cleaning mechanism can adhere to the surface of the guide rail, the cleaning mechanism can move along the guide rail with the rail-guided vehicle, facilitating comprehensive cleaning of the guide rail and reducing the workload of regular cleaning. Furthermore, multiple cleaning surfaces can form a three-dimensional cleaning effect, fully covering the working surface of the guide rail, reducing blind spots, extending the service life of the guide rail, and supporting the normal operation of the rail-guided vehicle.

[0059] Below, refer to Figures 1 to 8 Some embodiments of this application will be described in detail.

[0060] Figure 1 These are schematic diagrams of the structure of a rail-guided vehicle provided in some embodiments of this application; Figure 2 These are schematic diagrams of the cleaning mechanism provided in some embodiments of this application; Figure 3 This is a schematic diagram of the structure of the mounting bracket provided in some embodiments of this application; Figure 4 This is a schematic diagram of the structure of the first cleaning block provided in some embodiments of this application;

[0062] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a gravity direction are defined. These directions intersect each other; here, intersecting includes perpendicularly intersecting each other. For ease of understanding of the embodiments of this application, in... Figures 1 to 8 In the illustrated embodiment, the first direction, the second direction, and the direction of gravity are shown as examples where they intersect each other perpendicularly. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where these three directions intersect each other perpendicularly. For ease of explanation, as follows... Figures 1 to 8 As shown by the arrows, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the direction of gravity. Sometimes, the direction that arrow Z points in along the direction of gravity is called "above," and its opposite direction is called "below."

[0063] In the embodiments of this application, such as Figure 1 As shown, a first aspect of this application embodiment provides a cleaning mechanism 100 applicable to a rail-guided vehicle 1000, which travels along a guide rail 2000. The cleaning mechanism 100 is disposed on at least one side of the rail-guided vehicle 1000 along a first direction (X), where the first direction (X) is the forward / backward direction of the rail-guided vehicle 1000. The cleaning mechanism 100 has a first cleaning surface 111 and a second cleaning surface 121. The first cleaning surface 111 is configured to adhere to the upper surface of the guide rail 2000. The second cleaning surface 121 is disposed on at least one side of the guide rail 2000 along a second direction (Y) and is configured to adhere to the guide rail 2000 along the second direction (Y), which is perpendicular to the first direction (X) and the gravity direction (Z).

[0064] The Rail-Guided Vehicle 1000, also known as an RGV, can reciprocate on a fixed guide rail 2000 to participate in tasks such as handling and assembly. During the operation of the Rail-Guided Vehicle 1000, dust, mud, oil, and other foreign objects and stains can easily accumulate on the working surface of the guide rail 2000, affecting the operation and service life of the Rail-Guided Vehicle 1000.

[0065] It is understandable that the working surface of the guide rail 2000 can be Figure 1 The upper and side surfaces, namely the upper surface along the direction of gravity (Z) and the two side surfaces along the second direction (Y).

[0066] In other embodiments not shown, the working surface may include a lower surface along the direction of gravity (Z), and the cleaning mechanism 100 may be provided with a corresponding cleaning surface to clean it.

[0067] Optionally, the guide rail 2000 can be a linear motion guide rail, a circular motion guide rail, or a combination of both. This application does not limit this specific type of guide rail.

[0068] Optionally, the cleaning mechanism 100 may be connected to at least one side of the rail-guided vehicle 1000 along the first direction (X).

[0069] Alternatively, the cleaning mechanism 100 can be connected to the rail-guided vehicle 1000 by means of bolting, welding, bonding, riveting, etc.

[0070] It is understood that the cleaning mechanism 100 has a first cleaning surface 111 and a second cleaning surface 121. In this embodiment, the first cleaning surface 111 and the second cleaning surface 121 refer to surfaces with cleaning capabilities. The first cleaning surface 111 and the second cleaning surface 121 are respectively attached to the guide rail 2000 to clean the surface of the guide rail 2000.

[0071] Optionally, the first cleaning surface 111 can be a flat surface, a curved surface, or an uneven surface. The second cleaning surface 121 can be a flat surface, a curved surface, or an uneven surface. This application embodiment does not limit this.

[0072] Optionally, the first cleaning surface 111 can be any of the following structures: cleaning block, cleaning cloth, cleaning brush, cleaning strip, etc.

[0073] Alternatively, the second cleaning surface 121 can be a cleaning surface formed by any of the following structures: a cleaning block, a cleaning cloth, a cleaning brush, a cleaning strip, etc. The cleaning structure corresponding to the first cleaning surface 111 can be the same as the structure corresponding to the second cleaning surface 121, or they can be different. This embodiment does not limit this.

[0074] Understandably, the rail-guided carriage 1000 reciprocates on the top surface of the guide rail 2000, which is a working surface and easily accumulates dust and dirt. The sides of the guide rail 2000 can contact the guide wheel assembly, and similarly, dust and dirt easily accumulate there as well. The first cleaning surface 111 and the second cleaning surface 121 can clean the top and sides of the guide rail 2000. The aforementioned sides of the guide rail 2000 refer to the surfaces of both sides of the guide rail 2000 along the second direction (Y).

[0075] Because a cleaning mechanism 100 is provided in the forward and backward directions of the rail-guided vehicle 1000, and the first cleaning surface 111 and the second cleaning surface 121 of the cleaning mechanism 100 can fit into the surface of the guide rail 2000, the cleaning mechanism 100 can move along the guide rail 2000 with the rail-guided vehicle 1000. This facilitates comprehensive cleaning of the guide rail 2000 by the cleaning mechanism 100, reducing the workload of regular cleaning. In addition, multiple cleaning surfaces can form a three-dimensional cleaning, fully covering the working surface of the guide rail 2000, reducing blind spots, extending the service life of the guide rail 2000, and supporting the normal operation of the rail-guided vehicle 1000.

[0076] In the embodiments of this application, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, the cleaning mechanism 100 includes a mounting frame 130, a first cleaning block 110, and at least one second cleaning block 120. The mounting frame 130 is connected to the rail-guided vehicle 1000, and the first cleaning block 110 and the second cleaning block 120 are respectively connected to the mounting frame 130. The first cleaning block 110 has a first cleaning surface 111 and is configured to be disposed on the upper side of the guide rail 2000. The second cleaning block 120 has a second cleaning surface 121 and is configured to be disposed on at least one side of the guide rail 2000 along a second direction (Y).

[0077] Understandably, "upper side" refers to the area above the direction of gravity (Z).

[0078] Optionally, the shape of the first cleaning block 110 can be any one of a cuboid, cylinder, or prism, and the shape of the second cleaning block 120 can be any one of a cuboid, cylinder, or prism. The shape of the first cleaning block 110 can be the same as or different from the shape of the second cleaning block 120.

[0079] For example, the first cleaning block 110 is prism in shape, such as a triangular prism or a quadrangular prism, and the first cleaning surface 111 is rectangular in shape.

[0080] For example, the second cleaning block 120 is cuboid in shape, and the second cleaning surface 121 is rectangular in shape.

[0081] Optionally, the mounting bracket 130 can be connected to the rail-guided vehicle 1000 by means of bolting, welding, bonding, riveting, etc.

[0082] Optionally, the mounting bracket 130 can be connected to any location within the rail-guided vehicle 1000. For example, the mounting bracket 130 is connected to the body 300 of the rail-guided vehicle 1000.

[0083] Alternatively, the first cleaning block 110 can be connected to the mounting bracket 130 by means of bolts, adhesive, snap-fit, etc. Of course, a combination of the above-mentioned connection methods can also be used, and this embodiment does not limit this.

[0084] Alternatively, the second cleaning block 120 can be connected to the mounting bracket 130 by means of bolts, adhesive, snap-fit, etc. Of course, a combination of the above-mentioned connection methods can also be used, and this embodiment does not limit this.

[0085] Thus, multiple cleaning blocks are connected to the mounting bracket 130. The cleaning surface of the cleaning block is more likely to fit the surface of the guide rail 2000, which is conducive to modular design. The cleaning block and cleaning surface can be replaced in different cleaning scenarios to adapt to various cleaning needs.

[0086] In the embodiments of this application, the first cleaning block 110 includes at least one of nylon block, polyoxymethylene resin block, and foam block, and / or the second cleaning block 120 includes at least one of nylon block, polyoxymethylene resin block, and foam block.

[0087] For example, the first cleaning block 110 includes a nylon block. Nylon, or polyamide (PA), has characteristics such as wear resistance, corrosion resistance, high strength, and self-lubrication. The molecular chain structure of nylon enables it to form a micro-lubricating film during friction, reducing friction between directly contacting metals or hard materials and lowering the coefficient of friction.

[0088] As another example, the first cleaning block 110 includes a polyoxymethylene (POM) resin block, which is an engineering plastic that, similar to nylon blocks, has characteristics such as wear resistance, corrosion resistance, high strength, and self-lubrication.

[0089] Alternatively, the second cleaning block 120 can also be made of at least one of nylon blocks, polyoxymethylene resin blocks, or foam blocks. The material can be the same as the first cleaning block 110, which facilitates control over the cleaning effect and the degree of wear, and is beneficial for processing and maintenance.

[0090] Optionally, the first cleaning block 110 and / or the second cleaning block 120 may incorporate lubricants such as graphite, molybdenum disulfide, etc. This application does not limit this aspect.

[0091] Therefore, the cleaning block has good elasticity and wear resistance, and can effectively clean the surface of the guide rail 2000 through physical friction and adsorption, resulting in a long service life. In addition, the cleaning block also has a self-lubricating function, which can lubricate the guide rail 2000 while cleaning it.

[0092] In embodiments of this application, a cavity 140 is provided inside the first cleaning block 110, and a spring 150 in a compressed state is provided in the cavity 140. The spring 150 is configured to apply a force along the direction of gravity (Z) to the first cleaning surface 111; and / or, a cavity 140 is provided inside the second cleaning block 120, and a spring 150 is provided inside the cavity 140. The spring 150 in a compressed state is configured to apply a force along the second direction (Y) towards the guide rail 2000 to the second cleaning surface 121.

[0093] For example, such as Figure 7 , Figure 8 As shown, the second cleaning block 120 has a cavity 140 inside, and a spring 150 in a compressed state is provided in the cavity 140. The spring 150 can be a compression spring 150. The embodiments of this application do not limit the shape and size of the cavity 140, the number of springs 150, the amount of compression and the elastic coefficient, and are not limited to the embodiments shown in the figure.

[0094] In some embodiments not shown, a cavity 140 may be formed inside the first cleaning block 110, and a spring 150 in a compressed state may be provided in the cavity 140.

[0095] Optionally, the second cleaning block 120 or the first cleaning block 110 may have multiple cavities 140, and each cavity 140 is provided with at least one spring 150.

[0096] Optionally, the second cleaning block 120 or the first cleaning block 110 may have a cavity 140, and at least one spring 150 may be provided inside the cavity 140.

[0097] Therefore, the spring 150 applies elastic force to the cleaning surface through the cavity 140, so that the cleaning block is always in close contact with the surface of the guide rail 2000. When the cleaning mechanism 100 moves with the vehicle body 300, the spring 150 can automatically adjust the pressure according to the vibration, avoid cleaning dead corners caused by poor local contact, and improve the dynamic adaptability and cleaning effect of the cleaning mechanism 100.

[0098] In the embodiments of this application, the first cleaning block 110 has a first surface 112 on the side away from the rail-guided vehicle 1000 along the first direction (X), and the angle α between the first surface 112 and the first cleaning surface 111 is an acute angle.

[0099] For example, such as Figure 5As shown, viewed along the second direction (Y), the first cleaning block 110 is trapezoidal in shape. The base angle of the first cleaning block 110 on the side away from the traveling mechanism 200 of the rail-guided vehicle 1000 is an acute angle. Taking the cleaning mechanism 100 located on the front side of the rail-guided vehicle 1000 as an example, the trapezoidal shape of the first cleaning block 110 can improve the ability to remove foreign objects from the rail to a certain extent. That is, by using the acute base angle as a shovel, it can remove foreign objects such as dried soil and clumps of mud and sand attached to the surface of the guide rail 2000.

[0100] For example, when viewed along the second direction (Y), the first cleaning block 110 is a right trapezoid, that is, the base angle of the first cleaning block 110 on the side away from the walking mechanism 200 of the rail-guided vehicle 1000 is an acute angle, and the other base angle is a right angle, which can facilitate the connection of the first cleaning block 110 to the mounting bracket 130.

[0101] In some embodiments not shown, when viewed along the second direction (Y), the first cleaning block 110 may be triangular in shape. The angle between the first face 112 and the first cleaning face 111 is an acute angle.

[0102] In some embodiments not shown, the top surface of the second cleaning block 120 (i.e., viewed along the direction of gravity (Z)) may also be trapezoidal, and the angle between the side surface of the second cleaning block 120 away from the walking mechanism 200 and the second cleaning surface 121 is acute.

[0103] Since foreign objects tend to accumulate on the surface of the guide rail 2000, especially on the upper surface, designing the first cleaning block 110 into a specific shape can improve the ability of the first cleaning block 110 to remove foreign objects from the upper surface of the guide rail 2000 to a certain extent, and clean up foreign objects with adhesion, such as dried soil or clumps of mud and sand, thereby further improving the cleaning effect.

[0104] In the embodiments of this application, the angle α between the first surface 112 and the first cleaning surface 111 is in the range of 40° to 60°.

[0105] Optionally, the included angle α can be any one of 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, or 60°. Other values ​​will not be listed.

[0106] This further enhances the ability of the first cleaning block 110 to remove foreign objects from the surface of the guide rail 2000, thereby improving the cleaning effect of the first cleaning block 110.

[0107] In the embodiments of this application, the cleaning mechanism 100 includes a first pad 114, and a first cleaning block 110 has a first groove 113 on the side where the first cleaning surface 111 is located, and the first pad 114 is disposed in the first groove 113.

[0108] Optionally, there may be one or more first grooves 113.

[0109] Optionally, when viewed in the opposite direction of gravity (Z), the shape of the first groove 113 can be circular, elliptical, triangular, quadrilateral, or other polygonal. Alternatively, the shape of the first groove 113 can also be irregular, and this embodiment of the application does not limit this.

[0110] Optionally, when viewed in the opposite direction of gravity (Z), the shape of the first gasket 114 can be circular, elliptical, triangular, quadrilateral, or other polygonal. Alternatively, the shape of the first gasket 114 can also be irregular, and this embodiment of the application does not limit this.

[0111] Optionally, the shape of the first gasket 114 may be the same as or different from the shape of the first groove 113.

[0112] Optionally, the first gasket 114 may be flush with the edge of the first groove 113, and its thickness may be less than the depth of the first groove 113. The specific thickness of the first gasket 114 is not limited in this embodiment.

[0113] For example, such as Figure 2 , Figure 4 As shown, two first grooves 113 can be provided, and each first groove 113 is filled with a first gasket 114.

[0114] Optionally, during continuous operation of the cleaning mechanism 100, the first cleaning block 110 may experience dimensional reduction along the gravitational direction (Z) due to frictional wear, leading to insufficient contact between the first cleaning surface 111 and the guide rail 2000 surface. To ensure cleaning effectiveness, the installation position of the first cleaning block 110 can be finely adjusted axially; and / or, the contact between the first cleaning surface 111 and the guide rail 2000 can be restored by thinning the thickness of the first gasket 114. These adjustments effectively maintain the sealing performance of the cleaning assembly and the cleaning efficiency of the guide rail 2000 surface.

[0115] For example, the thickness of the first gasket 114 can be reduced by replacing it with a first gasket 114 of different thickness.

[0116] As another example, multiple first pads 114 stacked along the direction of gravity (Z) can be disposed in the first groove 113. The first cleaning surface 111 can be further fitted to the guide rail 2000 by reducing the number of first pads 114 disposed in the first groove 113.

[0117] Therefore, the first groove 113 is designed as a filling groove for the first gasket 114. The first gasket 114 can fill the installation gap between the first cleaning block 110 and the second cleaning block 120, preventing liquids, dust, or particles generated during the cleaning process from entering the installation gap between the cleaning block and the support structure, thus avoiding corrosion of the mounting bracket 130. Furthermore, by adjusting the thickness of the first gasket 114, the gap between the first cleaning block 110 and the guide rail 2000 can be adjusted, which helps to improve the fit between the surfaces of the first cleaning block 110 and the guide rail 2000.

[0118] In an embodiment of this application, the cleaning mechanism 100 includes two second cleaning blocks 120 and a second pad 123. The two second cleaning blocks 120 are respectively disposed on both sides of the guide rail 2000 along the second direction (Y). Along the second direction (Y), the second pad 123 is disposed on the side of each second cleaning block 120 away from the second cleaning surface 121, and the second pad 123 is located between the mounting bracket 130 and each second cleaning block 120.

[0119] Optionally, when viewed along the second direction (Y), the shape of the second gasket 123 can be circular, elliptical, triangular, quadrilateral, or other polygonal. Alternatively, the shape of the second gasket 123 can also be irregular, which is not limited in this embodiment.

[0120] It is understood that the second gasket 123 has a certain thickness, which enables the second cleaning surface 121 to fit against the side surface of the guide rail 2000, thereby increasing the friction. This application embodiment does not limit the specific thickness of the second gasket 123.

[0121] Optionally, during continuous operation of the cleaning mechanism 100, the second cleaning block 120 may experience dimensional reduction along the gravitational direction (Z) due to frictional wear, leading to insufficient contact between the second cleaning surface 121 and the guide rail 2000 surface. To ensure cleaning effectiveness, the installation position of the second cleaning block 120 can be finely adjusted axially; and / or, the contact between the second cleaning surface 121 and the guide rail 2000 can be restored by thinning the thickness of the second gasket 123. These adjustments effectively maintain the sealing performance of the cleaning assembly and the cleaning efficiency of the guide rail 2000 surface.

[0122] Optionally, the mounting bracket 130 may have a second groove, and the second gasket 123 may be disposed in the second groove.

[0123] Therefore, the second gasket 123 can disperse the contact pressure between the second cleaning block 120 and the mounting bracket 130, avoiding local stress concentration that could damage the second cleaning block 120 or the mounting bracket 130. Furthermore, by adjusting the thickness of the second gasket 123, the gap between the second cleaning block 120 and the guide rail 2000 can be adjusted, which helps improve the fit between the surfaces of the second cleaning block 120 and the guide rail 2000.

[0124] In the embodiments of this application, the mounting bracket 130 is bolted to the rail-guided vehicle 1000; the first cleaning block 110 is bolted to the mounting bracket 130, and / or the second cleaning block 120 is bolted to the mounting bracket 130.

[0125] For example, such as Figure 3 As shown, the mounting bracket 130 is connected to the body 300 of the rail-guided vehicle 1000 by bolts.

[0126] For example, such as Figure 3 As shown, the multiple first mounting holes 135 opened in the mounting bracket 130 can be elongated holes, that is, the dimension along the gravity direction (Z) is larger than the dimension along the second direction (Y), which facilitates the adjustment of the mounting height of the mounting bracket 130. This adapts to the height of the guide rail 2000 and adjusts the position of the cleaning block.

[0127] For example, such as Figure 4 As shown, the first cleaning block 110 has a second mounting hole 115, which can be a countersunk hole, which is beneficial for adjusting the installation position of the first cleaning block 110.

[0128] For example, such as Figure 6 As shown, the second cleaning block 120 has a third mounting hole 122, which can be a countersunk hole, which is beneficial for adjusting the installation position of the second cleaning block 120.

[0129] Understandably, the mounting bracket 130 also has bolt holes that mate with the second mounting hole 115 and the third mounting hole 122.

[0130] For example, bolted connections can be made using hex socket head cap screws.

[0131] Therefore, the bolted connection is simple and reliable, preventing the cleaning block from loosening or falling off during operation due to vibration, impact, or external force. It also facilitates the disassembly and maintenance of the cleaning block, and allows for better adjustment of its position.

[0132] In the embodiments of this application, the mounting bracket 130 includes a first plate 131 and a second plate 132 connected to each other. The first plate 131 is perpendicular to the first direction (X), and the second plate 132 is disposed on the side of the first plate 131 away from the side where the rail-guided vehicle 1000 is located along the first direction (X). A first clearance portion 133 is provided on the side of the first plate 131 along the gravity direction (Z), and the first clearance portion 133 is used to clearance the guide rail 2000. The first plate 131 is connected to the first cleaning block 110, and the second plate 132 is connected to the second cleaning block 120.

[0133] For example, such as Figure 3 As shown, the first plate 131 connects to two second plates 132. The first plate 131 is perpendicular to the first direction (X), and the second plate 132 is perpendicular to the second direction (Y). The second plate 132 can be connected to the first plate 131 by means of bonding, welding, plugging, etc.

[0134] For example, such as Figure 3 As shown, the second plate 132 can be welded to the first plate 131. The second plate 132 can have a second clearance portion 134 to cut off the weld and avoid installation difficulties due to the weld.

[0135] For example, such as Figure 3 As shown, viewed along the second direction (Y), the second plate 132 is a right trapezoid in shape, with the upper base plate located on the side of the second plate 132 away from the first plate 131 along the first direction (X), to prevent the cleaning mechanism 100 from injuring or colliding with people or objects. Of course, the upper base corner can also be rounded or covered with a cushioning element; this embodiment of the application does not limit this.

[0136] For example, the first clearance portion 133 is used to clear the guide rail 2000. The shape of the first clearance portion 133 can be adapted to the guide rail 2000. This application embodiment does not limit this.

[0137] For example, the first clearance portion 133 may be a groove formed by the first plate 131 recessed in the opposite direction of gravity (Z), so that the guide rail 2000 passes through the groove.

[0138] This facilitates the connection between the first cleaning block 110, the second cleaning block 120 and the mounting bracket 130. The first plate 131 can connect to and support the first cleaning block 110, and the second plate 132 can connect to and support the second cleaning block 120.

[0139] The second aspect of this application discloses a rail-guided vehicle 1000, which includes a vehicle body 300, at least one traveling mechanism 200 connected to the vehicle body 300, and a plurality of cleaning mechanisms 100 disclosed in the first aspect of this application connected to the vehicle body 300. Along a first direction (X), the cleaning mechanism 100 is disposed on at least one side of the traveling mechanism 200.

[0140] Optionally, the rail-guided vehicle 1000 includes a vehicle body 300 and a running mechanism 200 connected to the vehicle body 300. The running mechanism 200 can be at least one of a running wheel set, a guide wheel set, a transmission chain, and a transmission gear, wherein the running wheel set can include a driving wheel and a driven wheel. This application embodiment does not limit this.

[0141] For example, the cleaning mechanism 100 is disposed on the forward direction side of the traveling mechanism 200 to clean the surface of the guide rail 2000 that the rail-guided vehicle 1000 will come into contact with when it moves forward.

[0142] As another example, the cleaning mechanism 100 is disposed on the reversing side of the traveling mechanism 200 to clean the surface of the guide rail 2000 that the guide rail 1000 has contacted when it moves forward, or to clean the surface of the guide rail 2000 that the guide rail 1000 will contact when it moves backward.

[0143] As another example, the cleaning mechanism 100 is disposed on both sides of the walking mechanism 200 in the forward and backward directions to improve the cleaning effect.

[0144] For example, the walking mechanism 200 includes a set of guide wheels disposed on the chassis of the vehicle body 300, and the cleaning mechanism 100 may be disposed on the outside of the vehicle body 300 and located on both sides of the walking mechanism 200 in the forward and backward directions.

[0145] For example, the guide wheel assembly includes a first guide wheel and a second guide wheel. The rotation axis of the first guide wheel is aligned with the second direction (Y), and its circumferential surface is used to contact the top surface of the guide rail 2000. The rotation axis of the second guide wheel is aligned with the direction of gravity (Z), and its circumferential surface is used to contact the side surface of the guide rail 2000. It is understood that the guide wheel assembly can achieve multi-directional constraint on the traveling mechanism 200 through the first and second guide wheels, thereby enabling the rail-guided vehicle 1000 to move more stably and reliably along the extension direction of the guide rail 2000, reducing the possibility of the rail-guided vehicle 1000 deviating or swaying during travel.

[0146] Optionally, the cleaning mechanism 100 may be connected to at least one side of the vehicle body 300 along the first direction (X).

[0147] Alternatively, the cleaning mechanism 100 can be connected to the vehicle body 300 by means of bolting, welding, bonding, riveting, etc.

[0148] The specific solutions of the embodiments of this application are described below with reference to the accompanying drawings.

[0149] The rail-guided vehicle 1000, hereinafter referred to as RGV, currently uses a fixed brush structure for cleaning. This structure has certain drawbacks; the brushes cannot effectively cover the working surface of the guide rail 2000, potentially creating cleaning dead zones and hindering the operation of the wheels. While brushes can clean non-adhesive foreign objects, they cannot effectively clean areas with adhering foreign objects on the guide rail 2000. The rail-guided vehicle 1000 with a cleaning structure designed in this embodiment reduces cleaning dead zones on the guide rail 2000, ensures stable RGV movement, reduces wear on the wheels, and improves the cleanliness of the guide rail 2000 to a certain extent.

[0150] In a specific embodiment, such as Figure 2 As shown, the cleaning mechanism 100 includes a second cleaning block 120, a first cleaning block 110, and a mounting bracket 130. The mounting bracket 130 is connected to the vehicle body 300. The second cleaning block 120 has a second mounting hole 115, through which it is connected to the mounting bracket 130. Their mating relationship is achieved using hexagonal head screws. A second washer 123 can be installed on the mating surface of the second cleaning block 120 and the mounting bracket 130 to accommodate the continuously wearing guide rail 2000 contact surface. The first cleaning block 110 is bolted to the mounting bracket 130 through a first mounting hole 135. The first cleaning block 110 is used to clean the upper surface of the guide rail 2000, and its cleaning surface 111 is responsible for this cleaning function. Figure 5 As shown, viewed from the second direction (Y), the first cleaning block 110 is designed with a trapezoidal structure. Its bottom is the first cleaning surface 111. The trapezoidal structure can improve the foreign object removal capability of the guide rail 2000 to a certain extent.

[0151] In a specific embodiment, the first mounting hole 135 and the second mounting hole 115 are countersunk holes.

[0152] In a specific embodiment, the first cleaning block 110 also has a first groove 113. The function of the first groove 113 is mainly to reserve space for the first shim 114 while avoiding the installation space of the second cleaning block 120. The first cleaning block 110 needs to continuously contact and wear with the guide rail 2000 surface during the movement of the RGV, so it is necessary to adjust the reserved space of the first shim 114 in order to adjust and compensate for the wear of the first cleaning block 110.

[0153] In a specific embodiment, the mounting bracket 130 includes a first plate 131 and a second plate 132 welded together. The first plate 131 has a first clearance portion 133 and a first mounting hole 135. The first mounting hole 135 is an elongated hole oriented in the direction of gravity (Z) to facilitate adjustment in the direction of gravity (Z). The first clearance portion 133 provides clearance space between the mounting bracket 130 and the guide rail 2000. The first plate 131 is connected to the first cleaning block 110 by a threaded bolt connection. The mounting bracket 130 is a support structure made of metal, such as Q235B metal. The second clearance portion 134 of the mounting bracket 130 is to avoid the installation space of the bolts and also to cut off the weld seam to avoid installation difficulties caused by the weld seam.

[0154] The number of cleaning mechanisms 100 on the RGV can be 2 or 4, and they are set on one or both sides of the vehicle body 300 along the first direction (X). It depends on the actual application.

[0155] The cleaning mechanism 100 has the following advantages: it reduces blind spots in the removal of foreign objects from the guide rail 2000; it can clean up foreign objects with adhesion, such as dried soil and clumps of mud and sand; and the distance between the cleaning block and the guide rail 2000 is adjustable.

[0156] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0157] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.
