[0047] like Figures 1 to 9As shown, this embodiment provides a device for cleaning the outer skin of an empty rail 100, comprising a spray structure 1, a brush structure 2, and a purge structure. The spray structure 1 is used to spray water or detergent onto the empty rail 100. The spray structure 1 comprises a spray transverse pipe 11 and two spray risers 12. The spray transverse pipe 11 is spaced apart below the empty rail 100. The two spray risers 12 are respectively connected to the two ends of the spray transverse pipe 11 and spaced apart on both sides of the empty rail 100. The brush structure 2 comprises a bottom brush assembly 22, two side brush assemblies 21, and two end brush assemblies 23. The two side brush assemblies 21 are spaced apart on both sides of the empty rail 100. The side brush assemblies 21 comprise a side brush support frame 211 and a side brush body 212. The side brush body 212 is rotatably disposed on the side of the side brush support frame 211 facing the empty rail 100, and the side brush body 212 extends in a vertical direction for scrubbing the sides of the empty rail 100. The bottom brush assembly 22 includes a bottom brush body 221 and two bottom brush supports 222. The two bottom brush supports 222 are spaced apart on either side of the empty rail 100. The bottom brush bodies 221 are spaced apart below the empty rail 100 and rotatably positioned between the two bottom brush supports 222. They are used to scrub the underside of the empty rail 100, thereby improving the clarity of the view visible to passengers on the empty rail 100. Two end brush assemblies 23 are spaced apart on either side of the empty rail 100. The end brush assemblies 23 include end brush supports 231 and horizontal end brushes 232. The horizontal end brushes 232 are movably mounted vertically on the end brush supports 231. The horizontal end brushes 232 extend horizontally and are rotatable about their own axes. The horizontal end brushes 232 are used to contour the surfaces of the front and rear streamlined front ends of the empty rail 100, ensuring a comprehensive, no-dead-angle cleaning of the front and rear ends of the empty rail 100. The blowing structure is used to blow air toward the empty rail 100 to dry the outer skin of the empty rail 100 and ensure a clean effect of the outer skin of the empty rail 100.

[0048] Specifically, the blowing structure is a blower commonly used in the art. Its specific structure and principle refer to the existing technology and will not be described in detail here.

[0049] Specifically, when cleaning the outer skin of the rail 100, the rail stops at the specified station according to the signal instruction and moves to each cleaning station at the specified speed. The specific cleaning process is as follows:

[0050] When the empty rail 100 enters the car wash area, the entry light column at the front end of the car wash area detects that the empty rail 100 has entered the car wash area, and the cleaning device is started and enters the car wash mode. At the same time, the entry signal light turns red, prohibiting other empty rails 100 from entering.

[0051] The empty rail 100 enters the pre-washing station, and the spray structure 1 sprays water to the outer skin of the empty rail 100 to pre-wet the outer skin of the empty rail 100; then the spray structure 1 sprays detergent to the outer skin of the empty rail 100 so that the detergent adheres to the outer surface of the empty rail 100.

[0052] The empty rail 100 enters the brushing station for side brushing, bottom brushing and end cleaning. When brushing the sides and bottom, the control train runs at the specified speed to ensure that the entire side and bottom of the outer skin of the empty rail 100 are brushed; when brushing the end, the empty rail 100 needs to stop and the horizontal end brush 232 is rotated to achieve the brushing of the end of the empty rail 100.

[0053] After the brushing is completed, the empty rail 100 enters the spraying station, and the spraying structure 1 is used to wash away the dirt and detergent on the outer surface of the empty rail 100 to ensure the cleanliness of the empty rail 100.

[0054] After rinsing, the empty rail 100 enters the purge station, where the purge structure dries the outer skin of the empty rail 100. After cleaning, the outbound photoelectric column at the rear end of the car wash area detects that the empty rail 100 has completely left the car wash area, and the cleaning device is turned off. At the same time, the inbound signal light turns green, indicating that the next empty rail 100 is allowed to enter.

[0055] Specifically, the number of the spray structure 1, the side brush assembly 21, the bottom brush assembly 22, the end brush assembly 23 and the purging structure can be set as needed, that is, the empty rail 100 can be sprayed, brushed and purged multiple times according to needs, and no specific limitation is made here.

[0056] Illustratively, in this embodiment, the side brush body 212, the bottom brush body 221 and the horizontal end brush 232 are all cylindrical brush bodies, which are all sleeved on corresponding rotating shafts and rotatably arranged on corresponding supporting frames.

[0057] Alternatively, as Figure 2 As shown, the spray structure 1 further includes two top spray pipes 13, which are respectively disposed at one end of the two spray risers 12 away from the spray cross pipe 11, and each top spray pipe 13 is inclined along a side facing the empty rail 100. The above arrangement can spray water or detergent on the top side of the outer surface of the empty rail 100, thereby achieving comprehensive flushing of the outer surface of the empty rail 100 without any blind spots.

[0058] Further, continue to refer to Figure 2 The spraying horizontal pipe 11, the spraying vertical pipe 12 and the top spraying pipe 13 are all provided with a plurality of nozzles 110 at intervals, and the spraying angle of the nozzle 110 is at least 90 degrees. The above arrangement can spray the outer skin of the air rail 100 in all directions without dead angles to ensure the flushing effect.

[0059] Furthermore, when the sprayed fluid is clean water, the nozzle 110 is a jet nozzle 110 to ensure the flushing effect on the outer skin of the empty rail 100; when the sprayed fluid is detergent, the nozzle 110 uses an atomizing nozzle 110 to atomize the detergent into small droplets and then spray them out, so that the detergent effectively adheres to the outer surface of the empty rail 100 to enhance the reaction effect of the detergent and at the same time reduce the waste of detergent.

[0060] Specifically, in this embodiment, each nozzle 110 is equipped with a regulating valve for adjusting the flow rate, thereby adjusting the flow rate sprayed by the nozzle 110 according to demand. For example, the spray system installed in the pre-rinse station and the detergent spray station can adjust the flow rate of the nozzle 110 to a low level and select an atomizing nozzle 110 to improve the pre-wetting effect on the outer surface of the empty rail 100; the spray system installed in the rinse station can adjust the flow rate of the nozzle 110 to a high level and select a jet nozzle 110 to ensure a flushing effect, so that the outer surface of the empty rail 100 is free of residual dirt and detergent. The regulating valve is a structure that is already known in the prior art and will not be described in detail here.

[0061] Alternatively, as Figure 3 and Figure 4 As shown, the side brush assembly 21 further includes an adjustment arm 213, which is disposed between the side brush support frame 211 and the side brush body 212. The adjustment arm 213 can drive the side brush body 212 to move closer to or away from the idle rail 100. The above arrangement can adjust the amount of hair picked up by the side brush body 212, adjust the side brush body 212 to a suitable position, ensure the brushing effect, and effectively reduce the wear of the side brush body 212, thereby extending the service life of the side brush body 212.

[0062] Further, refer to Figure 4 The side brush assembly 21 also includes a first driving mechanism 214, which is fixed to the side brush support frame 211, and an adjusting arm 213 is rotatably arranged on the side brush support frame 211 and connected to the output end of the first driving mechanism 214. Driven by the first driving mechanism 214, the adjusting arm 213 can move closer to or away from the empty rail 100. For example, in this embodiment, the first driving mechanism 214 is a hydraulic rod, which has the advantages of small size, light weight and fast response speed. In addition, there is one first driving mechanism 214; in other embodiments, two second driving mechanisms 224 can also be provided, and the two second driving mechanisms 224 are correspondingly arranged at both ends of the side brush support frame 211, and the output ends of the two second driving mechanisms 224 are correspondingly connected to the two ends of the adjusting arm 213 to further improve the stability during the adjustment process.

[0063] Optionally, refer to Figure 4 The outer peripheral wall of the side brush body 212 is stepped. Figure 1The above arrangement enables the bristles of the side brush body 212 to better fit the outer skin of the empty rail 100, thereby comprehensively brushing the side surfaces of the outer skin of the empty rail 100.

[0064] Alternatively, as Figure 5 and Figure 6 As shown, the bottom brush assembly 22 further includes an adjustment frame 223, which is connected between the two bottom brush support frames 222. The bottom brush body 221 is rotatably disposed on the adjustment frame 223, and the adjustment frame 223 can drive the bottom brush body 221 to move closer to or away from the empty rail 100. The above arrangement can adjust the amount of hair picked up by the bottom brush body 221 to prevent excessive wear of the bottom brush body 221, and can also be applied to different models of empty rails 100, having good applicability.

[0065] Specifically, if Figure 6 As shown, the bottom brush assembly 22 also includes a second driving mechanism 224, which is fixed on the bottom brush support frame 222, and the adjustment frame 223 is rotatably arranged on the two bottom brush support frames 222 and connected to the output end of the second driving mechanism 224. Driven by the second driving mechanism 224, the adjustment frame 223 can move closer to or away from the empty rail 100. For example, in this embodiment, the second driving mechanism 224 is also a hydraulic rod. In addition, there is one second driving mechanism 224, that is, the second driving mechanism 224 is fixed on one of the bottom brush support frames 222; in other embodiments, two second driving mechanisms 224 can also be provided, and the two second driving mechanisms 224 are correspondingly arranged on the two bottom brush support frames 222, and the output ends of the two second driving mechanisms 224 are correspondingly connected to the two ends of the adjustment frame 223 to further improve the stability during the adjustment process.

[0066] Alternatively, as Figure 6 As shown, the bottom brush body 221 includes a first brush segment 2211, a second brush segment 2212 and a third brush segment 2213. The second brush segment 2212 is located between the first brush segment 2211 and the third brush segment 2213, and the size of the second brush segment 2212 is larger than the size of the first brush segment 2211 and the second brush segment 2212, that is, the first brush segment 2211, the second brush segment 2212 and the third brush segment 2213 are arranged in a "convex" shape to better fit the bottom side of the outer skin of the empty rail 100 and improve the cleaning effect.

[0067] Alternatively, as Figure 7 As shown, the outer wall of the horizontal end brush 232 is also stepped. Figure 8 The above arrangement enables the horizontal end brush 232 to better fit the end of the empty rail 100 , thereby improving the fit between the horizontal end brush 232 and the end of the empty rail 100 .

[0068] Optionally, continue with reference to Figure 7The end brush assembly 23 also includes an adjustment mechanism 233, which includes a horizontal guide rail 2331 and a vertical guide rail 2332. The horizontal guide rail 2331 extends horizontally and is disposed on the end brush support frame 231; the vertical guide rail 2332 extends vertically, with one end slidably disposed on the horizontal guide rail 2331 and the other end slidably disposed on the end brush support frame 231. The horizontal end brush 232 is slidably disposed on the vertical guide rail 2332. The above arrangement enables the position of the horizontal end brush 232 to be adjusted horizontally and vertically, thereby scrubbing the end of the empty rail 100 in all directions without blind spots.

[0069] Specifically, in this embodiment, the end brush assembly 23 further includes a maintenance ladder 234 . The maintenance ladder 234 is disposed on one side of the end brush support frame 231 and is used for operators to climb and perform maintenance operations.

[0070] Furthermore, the end brush assembly 23 also includes an anti-collision mechanism (not shown in the figure), which includes a torque coupling and a control member. The torque coupling is connected to the horizontal end brush 232 and can detect the external torque value of the horizontal end brush 232. The control member is connected to the torque coupling and the motor that drives the horizontal end brush 232 to rotate. When the torque value of the horizontal end brush 232 exceeds the set value, the control member will control the horizontal end brush 232 to return to the zero position (the zero position refers to the position of the horizontal end brush 232 farthest from the empty rail 100) to prevent the cleaning device from colliding with the empty rail 100 and causing damage to the empty rail 100, thereby having an anti-collision effect on the empty rail 100.

[0071] Specifically, the torque coupling, the control component and the motor are all existing devices disclosed in the prior art and will not be described in detail here.

[0072] Optionally, the outer skin cleaning device of the empty rail 100 also includes a water retaining structure 3, which includes two water retaining plates 31 respectively arranged on both sides of the empty rail 100. The water retaining plates 31 are used to stop splashing water droplets to prevent splashing water droplets from damaging other surrounding equipment, while also providing a good working environment for operators.

[0073] Specifically, if Figure 9 As shown, the water retaining plate 31 includes a main plate 311 and two side plates 312 disposed on both sides of the main plate 311. The side plates 312 are disposed at an angle to the main plate 311 to stop splashing water droplets to the greatest extent.

[0074] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
