Description

Technical Field

[0001] This application relates to the field of semiconductor equipment technology, and in particular to a brush suction component and a crane track cleaning device. Background Technology

[0002] In semiconductor manufacturing workshops, automated material handling systems are used to automate the handling of materials. These systems primarily consist of a handling system and a storage system. The handling system mainly comprises overhead crane tracks suspended from the ceiling (also known as overhead rails) and overhead cranes (also known as aerial transport vehicles) that travel on these tracks. The overhead crane tracks require regular maintenance and cleaning to ensure the smooth operation of the cranes.

[0003] The overhead crane tracks are installed on the ceiling. Currently, there is a lack of cleanroom equipment for the track systems of overhead rail transport equipment, and cleaning is mainly done manually. Regular maintenance is extremely inconvenient and labor-intensive. Manual maintenance requires working at the same height, and the corresponding cleaning area must be shut down, which seriously affects production efficiency. Manual cleaning is also prone to secondary pollution and poses safety hazards. Therefore, an automatic cleaning cart is needed on the production line to realize automatic track cleaning, improve cleaning efficiency, and reduce manpower. Utility Model Content

[0010] In some embodiments, the brush suction component further includes a cleaning brush, which is located on the side of the first sub-nozzle opposite to the second sub-nozzle in the first direction; and in the second direction, the cleaning brush is offset to one side relative to the center of the suction port of the first sub-nozzle; the second direction is perpendicular to both the first direction and the height direction of the first sub-nozzle.

[0011] According to another aspect of this application, a crane track cleaning device includes: a traveling device for traveling on the track surface of a crane track; a cleaning device for being placed on the track surface of the crane track, connected to the traveling device and located on one side of the traveling direction of the traveling device, the cleaning device including a first brush suction component, a second brush suction component, a third brush suction component, and an air path switching component, the first brush suction component for cleaning the track surface, the first brush suction component being a brush suction component as described above, the second brush suction component for cleaning the upper surface between cables located below the track surface, the third brush suction component for cleaning the guide rail located above the track surface that guides the traveling device to turn; and a dust collection module, the dust collection module being selectively connected to the first and second brush suction components through the air path switching component, and normally connected to the third brush suction component through the air path switching component.

[0012] In some embodiments, in the width direction of the track surface, the walking device is provided with first walking wheels on both sides, and the cleaning device is provided with a pair of second walking wheels on both sides, with each pair of second walking wheels spaced apart in the traveling direction of the walking device; the first brush suction component is provided between the two second walking wheels of each pair of second walking wheels.

[0013] In some embodiments, in the width direction of the track surface, the outer edges of the first traveling wheel and the outer edges of the second traveling wheel are flush, and the center of the suction port of the first brush suction component is located above the track surface; in the traveling direction of the traveling device, the center of the suction port of the first brush suction component is centrally located between the centers of the two second traveling wheels.

[0014] In some embodiments, the second suction component includes a second suction nozzle, a third brush, and a fourth brush.

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] First, refer to Figures 1 to 3 The following describes the overhead crane track 2 involved in this application. The overhead crane track 2 includes an outer track 21 and an inner track 22 spaced apart, and a guide track 23. The top surface of both the outer track 21 and the inner track 22 is a track surface 201. A cable bracket 24 is provided below the track surface 201, which is used to house the cable supplying power to the overhead crane. The guide track 23 is located above the track surface 201 and is used to guide the overhead crane to turn. The wheels on both sides of the overhead crane travel on the track surface 201, and the steering wheels on the top of the overhead crane achieve turning at branch points under the guidance of the guide track 23.

[0043] This application proposes a crane track cleaning device 1, which can clean multiple objects such as the track surface 201, the upper surface of the cable bracket 24, and the contact surface of the guide track 23 for contact with the steering wheel 120.

[0044] refer to Figures 1 to 3 An embodiment of the overhead crane track cleaning device 1 of this application includes a walking device 100, a sweeping device 200, and a dust collection module 300. The walking device 100 drives the sweeping device 200 and the dust collection module 300 to move together, and the dust collection module 300 sweeps and collects dust from the multiple objects to be cleaned through the sweeping device 200.

[0045] In this application, the direction of travel of the traveling device 100 refers to the direction of movement of the traveling device 100 when the overhead crane track cleaning equipment 1 performs automatic cleaning operations. The traveling device 100 moves along the length of the track surface 201. The width direction of the track surface 201 is consistent with the arrangement direction of the outer track 21 and the inner track 22. Both the direction of travel of the traveling device 100 and the width direction of the track surface 201 are horizontal. Figure 1 The width of the overhead crane track cleaning equipment 1 is also along the Y direction.

[0046] The traveling device 100 is used to travel on the track surface 201 of the overhead crane track 2. The traveling device 100 can be connected to the overhead crane drive or configured as an integral part of the overhead crane. In the width direction of the track surface 201, the traveling device 100 has first traveling wheels 110 on both sides, and is supported on the track surface 201 of the outer track 21 and the track surface 201 of the inner track 22, respectively. The top of the traveling device 100 has a steering wheel 120. The steering wheel 120 is used to cooperate with the guide track 23.

[0047] In this embodiment, the cleaning device 200 is installed on the track surface 201 of the crane track 2, connected to the traveling device 100, and located in front of the traveling device 100 in its traveling direction. Specifically, the cleaning device 200 is positioned in front of the traveling device 100. The cleaning device 200 can clean the aforementioned objects first, thereby ensuring that the environment where the traveling device 100 or the crane passes is clean and pollution-free. Second traveling wheels 270 are respectively provided on both sides of the cleaning device 200, and the second traveling wheels 270 on both sides are supported on the track surface 201 of the outer track 21 and the track surface 201 of the inner track 22. A guide wheel 2001 is provided on the top of the cleaning device 200. The guide wheel 2001 is used to contact and cooperate with the guide track 23.

[0048] Figure 1 In this configuration, the cleaning device 200 is located in front of the traveling device 100 in the traveling direction and to the right of the traveling device 100. For other embodiments, please refer to... Figure 1 Alternatively, the cleaning device 200 can be located behind the traveling device 100 in the direction of travel. In this case, the cleaning device 200 is located to the left of the traveling device 100. In this way, the track surface 201 traversed by the traveling device 100 is cleaned by the cleaning device 200, ensuring that the environment where the traveling device 100 or the overhead crane passes is clean and free from pollution.

[0049] Optional, see reference Figure 1 and Figure 2 The overhead crane track cleaning equipment 1 also includes a base plate 400, on which the traveling device 100 and the cleaning device 200 are mounted and arranged symmetrically about the center of the base plate 400. In the width direction of the track surface 201, the first traveling wheels 110 on both sides of the traveling device 100 are arranged symmetrically about the center of the base plate 400; the second traveling wheels 270 on both sides of the cleaning device 200 are arranged symmetrically about the center of the base plate 400.

[0050] refer to Figures 3 to 6The cleaning device 200 includes a first suction brush 210, a second suction brush 220, a third suction brush 230, and an air path switching component 240. The first suction brush 210 is used to clean the track surface 201, the second suction brush 220 is used to clean the upper surface of the cable bracket 24 located below the track surface 201, and the third suction brush 230 is used to clean the guide track 23 located above the track surface 201 that guides the walking device 100 to turn. The first suction brush 210, the second suction brush 220, the third suction brush 230, and the air path switching component 240 can all be mounted on the aforementioned base plate 400; all three have dust sweeping and dust suction functions.

[0051] The dust collection module 300 is selectively connected to the first suction component 210 and the second suction component 220 via the air path switching component 240, and is normally connected to the third suction component 230 via the air path switching component 240. The dust collection module 300 provides negative pressure for the first suction component 210, the second suction component 220 and the third suction component 230 during dust collection, and collects the dust sucked up by the first suction component 210, the second suction component 220 and the third suction component 230 during operation.

[0052] The dust collection module 300 is always connected to the third brush suction component 230, meaning the third brush suction component 230 always has a dust collection function. The dust collection module 300 is selectively connected to the first brush suction component 210 and the second brush suction component 220 via the air path switching component 240, meaning the dust collection module 300 either enables the first brush suction component 210 to have a dust collection function or enables the second brush suction component 220 to have a dust collection function.

[0053] Therefore, the overhead crane track cleaning device 1 of this application can have two cleaning modes. In the first cleaning mode, both the first brush suction component 210 and the third brush suction component 230 are in working condition, which can clean the track surface 201 and the guide track 23 at the same time. In the second cleaning mode, both the second brush suction component 220 and the third brush suction component 230 are in working condition, which can clean the upper surface of the cable bracket 24 and the guide track 23 at the same time.

[0054] The overhead crane track cleaning device 1 of this application, by setting an air path switching component 240, can clean different objects in the overhead crane track 2 as needed.

[0055] Optional, see reference Figure 2 , Figure 6The dust collection module 300 is suspended below the substrate 400. A through-hole shaft 410 is connected to the substrate 400. The top end of the through-hole shaft 410 communicates with the air path switching component 240, and the bottom end of the through-hole shaft 410 communicates with the suction port 341 of the dust collection module 300. The dust collection module 300 includes a front electrical control box 310, a rear electrical control box 320, a dust collection unit 330, and a dust collection unit 340, which are spaced apart. The front electrical control box 310 and the rear electrical control box 320 are located below the substrate 400 and are both connected to the substrate 400. The dust collection unit 330 is centrally located and connected to the substrate 400, the front electrical control box 310, and the rear electrical control box 320. The dust collection unit 340 is installed at the bottom of the dust collection unit 330 and has the aforementioned suction port 341.

[0056] The front control box 310 and the rear control box 320 form the control unit of the crane track cleaning equipment 1, which is used to control the operation of the crane, the dust collection unit 340, the sweeping device 200, etc. However, it should be noted that the arrangement of the control unit is not limited to two control boxes, one in front and one in back.

[0057] Optionally, the dust collection unit 330 has a mounting rail 331 at its bottom, and the suction unit 340 is detachably fixed to the mounting rail 331. The suction and dust collection module 300 also includes a protective plate 350, which is connected to the front electrical control box 310 and the rear electrical control box 320 and covers the suction unit 340. The suction unit 340 can be assembled or disassembled after the protective plate 350 is removed.

[0058] When the overhead crane track cleaning equipment 1 of this application is used in conjunction with an overhead crane, the cleaning device 200 is set in front of the traveling device 100, and the overhead crane can clean the track system in real time without stopping the operation, thereby improving cleaning efficiency, reducing personnel input, ensuring the cleanliness of the track, preventing particulate matter from accumulating and volatilizing on the track surface, ensuring the cleanliness of the workshop environment, and providing environmental protection for product yield.

[0059] refer to Figures 7 to 10 The air path switching component 240 includes a negative pressure chamber 241, a switching plate 242, a switching motor 243, a first suction channel 244, and a second suction channel 245. The negative pressure chamber 241 is connected to the dust collection module 300 and the third brush suction component 230. The output end 2431 of the switching motor 243 is drivenly connected to the switching plate 242. The switching plate 242 is movably disposed in the negative pressure chamber 241 and can switch between a first position and a second position under the drive of the switching motor 243. When the switching plate 242 is in the first position, the first suction channel 244 is connected to the negative pressure chamber 241 while the second suction channel 245 is isolated from the negative pressure chamber 241. When the switching plate 242 is in the second position, the second suction channel 245 is connected to the negative pressure chamber 241 while the first suction port is isolated from the negative pressure chamber 241.

[0060] The negative pressure chamber 241 is located at the top of the through hole shaft 410, and the bottom end of the negative pressure chamber 241 is connected to the inner cavity of the through hole shaft 410.

[0061] The switching plate 242 moves along the width of the track surface 201. The switching plate 242 is located below the switching motor 243. The switching motor 243 is, for example, a linear motor, whose output end 2431 drives the switching plate to reciprocate via the connecting member 2432. The switching plate 242 and the switching motor 243 can also be connected via a linear motion conversion mechanism. This mechanism converts the rotational motion of the output end 2431 of the switching motor 243 into the linear motion of the switching plate 242. It should be noted that the direction of movement of the switching plate 242 is not limited to the width of the track surface 201; for example, it can be set at an angle to the width of the track surface 201.

[0062] The first suction channel 244 is connected to the first suction component 210 via a first flexible hose 2441, and the second suction channel 245 is connected to the second suction component 220 via a second flexible hose 2451. Both the first suction channel 244 and the second suction channel 245 have an interface extending along the width direction of the track surface 201, which is used to connect the aforementioned flexible hoses.

[0063] Optional, see reference Figure 7 and Figure 8 The first suction channel 244 includes a first outlet 2442, and the second suction channel 245 includes a second outlet 2452. The switching plate 242 includes a first through hole 2421 and a second through hole 2422. When the switching plate 242 is in the first position, the first through hole 2421 connects the negative pressure chamber 241 and the first outlet 2442, and the second through hole 2422 is offset from the second outlet 2452, thus the switching plate 242 blocks the second outlet 2452. When the switching plate 242 is in the second position, the second through hole 2422 connects the negative pressure chamber 241 and the second outlet 2452, and the first through hole 2421 is offset from the first outlet 2442, thus the switching plate 242 blocks the first outlet 2442.

[0064] In the specific configuration, the first outlet 2442 and the second outlet 2452 are arranged side by side in the traveling direction of the walking component; the first through hole 2421 and the second through hole 2422 both pass through the switching plate 242, and the first through hole 2421 and the second through hole 2422 are staggered in both the traveling direction of the walking component and the width direction of the track surface 201. Specifically, the first outlet 2442 and the first through hole 2421 are aligned in the traveling direction of the walking component, and the second outlet 2452 and the second through hole 2422 are aligned in the traveling direction of the walking component.

[0065] Both the first suction channel 244 and the second suction channel 245 are L-shaped. The first outlet 2442 and the second outlet 2452 are located inside the negative pressure chamber 241 and extend vertically. The first inlet 2443 of the first suction channel 244 and the second inlet 2453 of the second suction channel 245 both extend horizontally, protruding from both sides of the negative pressure chamber 241. In other embodiments, the first inlet 2443 of the first suction channel 244 and the second inlet 2453 of the second suction channel 245 both extend vertically and protrude from the top of the negative pressure chamber 241.

[0066] When the first through-hole 2421 is connected to the first outlet 2442, the second through-hole 2422 and the second outlet 2452 are misaligned, so the negative pressure provided by the vacuum module can only act on the first brush suction component 210. (Refer to...) Figure 9 Similarly, when the second through-hole 2422 is connected to the second outlet 2452, the first through-hole 2421 and the first outlet 2442 are misaligned, so the negative pressure provided by the vacuum module can only act on the second brush suction component 220. (Refer to...) Figure 10 .

[0067] Optional, see reference Figure 7 and Figure 8 The first outlet 2442, the second outlet 2452, the first through hole 2421, and the second through hole 2422 are all circular holes with the same specifications. Furthermore, in the traveling direction of the traveling component, the distance between the center of the first through hole 2421 and the center of the second through hole 2422 is greater than or equal to twice the diameter of the first through hole 2421. Through these means, it can be ensured that when the first through hole 2421 is connected to the first outlet 2442, the second through hole 2422 is offset from the second outlet 2452; and when the second through hole 2422 is connected to the second outlet 2452, the first through hole 2421 is offset from the first outlet 2442.

[0068] To facilitate automated control of switching motor 243 using the control unit. (Reference) Figure 7 and Figure 8 The gas path switching component 240 also includes a first position sensor 246 and a second position sensor 247. When the first position sensor 246 is triggered by the switching plate 242, it provides a signal indicating that the switching plate 242 is in a first position. When the second position sensor 247 is triggered by the switching plate 242, it provides a signal indicating that the switching plate 242 is in a second position.

[0069] In practice, a control unit can be used to control the operation of the switching motor 243. When the control unit receives a signal that the first position sensor 246 has been triggered, the control unit controls the switching motor 243 to stop working, keeping the switching plate 242 in the first position. Similarly, when the control unit receives a signal that the second position sensor 247 has been triggered, the control unit controls the switching motor 243 to stop working, keeping the switching plate 242 in the second position.

[0070] The first position sensor 246 and the second position sensor 247 are disposed on both sides of the switching plate 242, specifically on opposite side walls of the negative pressure chamber 241. Optionally, the first position sensor 246 and the second position sensor 247 may be, for example, pressure sensors, distance sensors, photoelectric sensors, etc. This application does not impose specific limitations on this.

[0071] refer to Figures 11 to 13 As shown, the cleaning device 200 also includes a first lifting mechanism 250 that is tractively connected to the first brush suction component 210. The first brush suction component 210 switches between a first working position and a first non-working position under the drive of the first lifting mechanism 250. In response to the first position sensor 246 being triggered, the first lifting mechanism 250 drives the first brush suction component 210 to move to the first working position.

[0072] The first brush suction component 210 has a first working position and a first non-working position in the vertical direction, with the first working position located below the first non-working position. For example... Figure 4 As shown, in the first working position, the first brush suction component 210 can perform sweeping and vacuuming actions on the track surface 201; as Figure 3 As shown, in the first non-working position, the first brush suction component 210 is raised and cannot perform sweeping and vacuuming actions.

[0073] In this application, corresponding to the track surface 201 of the inner track 22 and the track surface 201 of the outer track 21, the cleaning device 200 has first brush suction components 210 on both sides. The first lifting mechanism 250 can be, for example, a linear motor module or a lead screw mechanism. The linear motor module simultaneously drives the first brush suction components 210 on both sides to lift. In other embodiments, each first brush suction component 210 can be equipped with a linear motor module.

[0074] The first lifting mechanism 250 can be specifically mounted on the base plate 400. By mounting the first lifting mechanism 250, when cleaning of the track surface 201 is not required, the first brush suction component 210 is raised to the first non-working position, thereby reducing the resistance when the overhead crane track cleaning equipment 1 is moving.

[0075] like Figure 19As shown, the cleaning device 200 also includes a second lifting mechanism 260 that is tractively connected to the second brush suction component 220. The second brush suction component 220 switches between a second working position and a second non-working position under the drive of the second lifting mechanism 260. In response to the second position sensor 247 being triggered, the second lifting mechanism 260 drives the second brush suction component 220 to move to the second working position.

[0076] The second brush suction component 220 has a second working position and a second non-working position in the vertical direction, with the second working position located below the second non-working position. For example... Figure 5 As shown, in the second working position, the second brush suction component 220 can perform sweeping and vacuuming actions on the upper surface of the cable bracket 24; as Figure 3 As shown, in the second non-working position, the second brush suction component 220 is raised and cannot perform sweeping and vacuuming actions.

[0077] In this application, the cable bracket 24 is also provided at two locations corresponding to the inner track 22 and the outer track 21. The cleaning device 200 has two corresponding second brush suction components 220. The second lifting mechanism 260 can be, for example, a linear motor module or a lead screw mechanism. The second lifting mechanism 260 can simultaneously drive the lifting of both second brush suction components 220. In other embodiments, each second brush suction component 220 can be equipped with one second lifting mechanism 260.

[0078] The second lifting mechanism 260 can be specifically mounted on the base plate 400. By mounting the second lifting mechanism 260, when cleaning the upper surface of the cable bracket 24 is not required, the second brush suction component 220 is raised to the second non-working position, thereby reducing the resistance when the overhead crane track cleaning equipment 1 is moving.

[0079] In other embodiments, the cleaning device 200 further includes a manual control mechanism. When the first position sensor 246 is triggered, the first lifting mechanism 250 drives the first brush suction component 210 to move to the first working position under the control of the manual control mechanism. When the second position sensor 247 is triggered, the second lifting mechanism 260 drives the second brush suction component 220 to move to the second working position under the control of the manual control mechanism.

[0080] refer to Figure 1 , Figure 2 , Figure 13 The cleaning device 200 has a pair of second walking wheels 270 on each side, and each pair of second walking wheels 270 is spaced apart in the direction of travel of the walking device 100; a first brush suction component 210 is provided between the two second walking wheels 270 of each pair of second walking wheels 270.

[0081] The second travel wheels 270 on both sides are placed on the inner track 22 and the outer track 21, respectively. Taking a pair of second travel wheels 270 placed on the inner track 22 as an example, the first brush suction component 210 is located between the two second travel wheels 270.

[0082] One scenario, see reference Figure 13 The overhead crane track 2 includes both straight sections 202 and curved sections 203. Therefore, when the overhead crane track cleaning device 1 travels on the overhead crane track 2, it will encounter turning situations, that is, transitioning from straight sections 202 to curved sections 203, and both straight sections 202 and curved sections 203 may require cleaning. To prevent the first brush suction component 210 from failing to clean the curved section 203 when the overhead crane track cleaning device 1 turns, the following configuration is made in this application.

[0083] In the width direction of the track surface 201, the outer edges of the first traveling wheel 110 and the second traveling wheel 270 are flush, and the center of the suction port of the first brush suction component 210 is located above the track surface 201. In this way, the first brush suction component 210 can perform suction cleaning on the track surface 201.

[0084] Optionally, the center of the suction port of the first brush suction component 210 is offset from the outer edge of the second travel wheel 270 towards the center of the cleaning device 200. For example... Figure 13 As shown, the center of the suction port of the first brush suction component 210 is located at position L1, which is more biased toward the center of the cleaning device 200 than the L2 position of the outer edge of the second walking wheel 270.

[0085] The second travel wheels 270 on each side of the sweeping device 200 are arranged in pairs. During the turning process of the sweeping device 200, the front or rear second travel wheels 270 may partially detach from the track surface 201. Since the center of the suction port of the first brush suction component 210 is offset from the outer edge of the second travel wheel 270 towards the center of the sweeping device 200, the center of the suction port of the first brush suction component 210 can always be located above the track surface 201, or even if it is suspended in the air, it is for a very short time.

[0086] Optionally, in order to ensure that the first brush suction component 210 can always clean the track surface 201 during the conversion process, the center A of the suction port of the first brush suction component 210 is located in the center between the wheel centers C1 and C2 of the two second walking wheels 270 in the traveling direction of the walking device 100.

[0087] refer to Figure 14 and Figure 15The curved arrow P indicates the turning direction of the sweeping device 200. The second traveling wheels 270 on each side of the sweeping device 200 are arranged in pairs. The two inner second traveling wheels 270 are located on the inner track surface 201; the two outer second traveling wheels 270 are located on the outer track surface 201.

[0088] Taking the two inner second traveling wheels 270 as an example, during the turning process of the sweeping device 200, L3 in the figure represents the trajectory of the inner side of the second traveling wheels 270, and its turning radius is R1. The sweeping device 200 is a wheeled device, and during the turning process, the inner sides of the front and rear second traveling wheels 270 will successively appear suspended, that is, they will exceed the inner edge of the track surface 201.

[0089] In this embodiment, the turning radius R2 of the center A of the suction port of the first brush suction component 210 is smaller than the turning radius R1 of the wheel center of the second traveling wheel 270. Therefore, the center A of the suction port of the first brush suction component 210 is closer to the turning center C3. Thus, when the inner side of the second traveling wheel 270 is suspended in the air, the center A of the suction port of the first brush suction component 210 remains between the inner edge and the outer edge of the track surface 201, i.e., it remains on the track surface 201. This ensures that even during turning, the center A of the suction port of the first brush suction component 210 remains above the track surface 201.

[0090] Optional, see reference Figure 12 , Figure 16 and Figure 17 The first suction component 210 includes a first suction nozzle 211 and a brushing part 212. The bottom of the first suction nozzle 211 has a first sub-suction nozzle 2111 and a second sub-suction nozzle 2112 spaced apart along a first direction. The top of the first suction nozzle 211 has a first dust outlet 2113, which communicates with both the first sub-suction nozzle 2111 and the second sub-suction nozzle 2112. The first direction is perpendicular to the height direction of the first suction nozzle 211. The brushing part 212 is connected to the first suction nozzle 211 and located between the first sub-suction nozzle 2111 and the second sub-suction nozzle 2112. Both the first sub-suction nozzle 2111 and the second suction nozzle 2112 have a first dust suction port 2114.

[0091] The first dust outlet 2113 is connected to the first suction channel 244 via the first flexible hose 2441. In the traveling direction of the walking device 100, the first suction nozzle 211 is located in front of the second suction nozzle 221.

[0092] When the overhead crane track cleaning equipment 1 is in operation, the negative pressure provided by the first sub-suction nozzle 2111 and the second sub-suction nozzle 2112 sucks away the dust swept up by the brush sweeping part 212. The first brush suction part 210 performs adsorption, sweeping and adsorption actions on the track surface 201, and achieves a good cleaning effect through two adsorptions and one sweeping.

[0093] Furthermore, in the height direction of the first suction nozzle 211, the first suction port 2114 of the first sub-suction nozzle 2111 is located above the first suction port 2114 of the second sub-suction nozzle 2112.

[0094] The height of the first suction nozzle 211 is vertical. The first dust suction port 2114 of the first sub-suction nozzle 2111 and the first dust suction port 2114 of the second sub-suction nozzle 2112 are located at their bottoms respectively. The dust suction port (working surface) of the first sub-suction nozzle 2111 is higher, so when the first brush suction component 210 is working, when the second sub-suction nozzle 2112 contacts the track surface 201, the working surface of the first sub-suction nozzle 2111 is still a distance away from the track, allowing it to first absorb and remove larger dust particles.

[0095] refer to Figure 12 , Figure 17 Along the height of the first suction nozzle 211, from its top to its bottom, the distance between the first sub-suction nozzle 2111 and the second sub-suction nozzle 2112 gradually increases. In other words, from top to bottom, the distance between the first sub-suction nozzle 2111 and the second sub-suction nozzle 2112 gradually increases, thereby facilitating the placement of the brushing part 212.

[0096] As shown in the figure, the first brush suction component 210 also includes a pair of support plates 213, located on both sides of the first suction nozzle 211 in a second direction. The support plates 213 are connected to both the first sub-suction nozzle 2111 and the second sub-suction nozzle 2112. The second direction is perpendicular to both the first direction and the height direction of the first suction nozzle 211. The simultaneous connection of both support plates 213 to the first sub-suction nozzle 2111 and the second sub-suction nozzle 2112 improves the structural stability of the first brush suction component 210. The brushing part 212 is connected to the support plates 213. The first brush suction component 210 also includes a mounting bracket 214 connected to the support plates 213. The mounting bracket 214 is connected to the first lifting mechanism 250.

[0097] The specific implementation method of the brush sweeping unit 212 is not limited.

[0098] In some embodiments, the brush sweeping unit 212 includes a rotary motor 2121 and a first brush 2122 driven by the rotary motor 2121, the first brush 2122 being a roller brush. The rotary motor 2121 drives the roller brush to rotate, and the negative pressure provided by the first sub-suction nozzle 2111 and the second sub-suction nozzle 2112 sucks away the dust swept up by the roller brush.

[0099] A rotary motor 2121 is mounted on the first suction nozzle 211. Specifically, the motor shaft of the rotary motor 2121 is connected and fixed to the support plates 213 on both sides via bearings. The rotation axis of the roller brush is parallel to the track surface 201 and perpendicular to the width direction Y of the track surface 201. Optionally, the rotary motor 2121 is a hollow cup motor, and the roller brush is fitted onto the rotor of the hollow cup motor. With this configuration, the roller brush and the rotary motor 2121 are integrated together, resulting in a compact structure.

[0100] refer to Figure 3 The first brush suction component 210 also includes a second brush 215, which serves as a cleaning brush. The second brush 215 is located on the side of the first suction nozzle 211 opposite to the second suction nozzle 221. In other words, the second brush 215 is located in front of the first suction nozzle 211, and can clean the track surface 201 before the first suction nozzle 211 performs the suction action. Thus, the first brush suction component 210 of this application can perform sweeping, suction, secondary sweeping, and secondary suction on the track surface 201, thereby achieving a better cleaning effect.

[0101] Furthermore, in the second direction, i.e., the width direction of the track surface 201, the second brush 215 is offset to one side relative to the center of the first suction port 2114 of the first sub-suction nozzle 2111. Specifically, the second brush 215 is located outside the first suction nozzle 211 and extends forward at an angle. In this way, the second brush 215 can concentrate and sweep dust to the area in front of the first sub-suction nozzle 2111 that can be covered, thereby facilitating the first sub-suction nozzle 2111 to adsorb dust.

[0102] refer to Figures 18 to 20 In some embodiments, the second suction component 220 includes a second suction nozzle 221, a third brush 222, and a fourth brush 223. In the traveling direction of the walking device 100, the third brush 222 is located in front of the second suction nozzle 221, and the fourth brush 223 is located behind the second suction nozzle 221. The second suction nozzle 221 has a second dust outlet 2211 at its top and a second suction port 2212 at its bottom. The second dust outlet 2211 is connected to the second suction channel 245 via a second flexible hose 2451. The second suction nozzle 221 is connected to the output end 2431 of the second lifting mechanism 260.

[0103] The second suction nozzle 221 is equipped with brushes at both the front and rear, which can clean, absorb, and perform secondary cleaning on the upper surface of the cable bracket 24, achieving a good cleaning effect.

[0104] Optionally, in the vertical direction, the working surface of the third brush 222 is higher than the working surface of the fourth brush 223. That is, the working surface of the third brush 222 is at a higher position. The working surfaces of both the third brush 222 and the fourth brush 223 are their bottom surfaces.

[0105] When the second brush suction component 220 is working, there is still a distance between the working surface of the third brush 222 and the cable bracket 24 when the working surface of the fourth brush 223 contacts the cable bracket. The third brush 222 is located in front of the second suction nozzle 221, allowing it to first remove larger dust particles. Then, the second suction nozzle 221 absorbs smaller dust particles. Finally, the fourth brush 223 performs a secondary cleaning, achieving a better cleaning effect.

[0106] Optionally, in the traveling direction of the walking device 100, the second suction nozzle 221 includes two second suction ports 2212, one higher than the other. As shown in the figure, the front second suction port 2212 is positioned higher vertically, while the rear second suction port 2212 is positioned lower. In this way, the front second suction port 2212 can absorb larger dust particles that have not been swept away by the third brush 222, while the rear second suction port 2212 can absorb dust particles attached to the cable bracket 24.

[0107] refer to Figure 1 , Figure 3 and Figure 11 In some embodiments, the top of the cleaning device 200 is provided with a guide wheel 2001, the rotation plane of the guide wheel 2001 is parallel to the track surface 201; in the traveling direction of the walking device 100, the third brush suction component 230 is provided behind the guide wheel 2001.

[0108] The guide wheel 2001 cooperates with the guide rail 23 to guide the cleaning device 200 to turn. The third brush suction component 230 is used to clean the guide rail 23 to ensure good contact between the steering wheel 120 and the guide rail 23 when the rear walking module turns.

[0109] Optionally, the third suction component 230 includes a third suction nozzle 231, a fifth brush 232, and a sixth brush 233. The fifth brush 232 and the sixth brush 233 are arranged sequentially on one side of the guide wheel 2001. In the vertical direction, the tip of the sixth brush 233 is higher than or equal to the tip of the fifth brush 232. The third suction component 230 is fixedly mounted on the top of the cleaning device 200. The third suction nozzle 231 is constantly connected to the negative pressure channel via a flexible hose.

[0110] In this embodiment, the sweeping device 200 is located in front of the traveling device 100 in the traveling direction, and the fifth brush 232 and the sixth brush 233 are arranged sequentially behind the guide wheel 2001. In the provided embodiment, when the sweeping device 200 is located behind the traveling device 100 in the traveling direction, the fifth brush 232 and the sixth brush 233 are arranged sequentially in front of the guide wheel 2001. The guide track 23 includes a positioning surface 2301 and a guide surface 2032. The positioning surface 2301 is horizontal, and the guide surface 2032 is vertical. The positioning surface 2301 is located above the guide wheel 2001 to limit the guide wheel 2001 in the vertical direction. The guide surface 2032 is used to contact the outer peripheral surface of the guide wheel 2001.

[0111] In this application, the tip of the sixth brush 233 is higher than or equal to the tip of the fifth brush 232. The fifth brush 232 is used to clean the guide surface 2032 of the guide rail 23, or to clean both the guide surface 2032 and the positioning surface 2301 of the guide rail 23. The sixth brush 233 is used to clean the positioning surface 2301. The third suction nozzle 231 can be configured to simultaneously suction the guide surface 2032 and the positioning surface 2301.

[0112] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0113] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
