Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0016] Please see Figures 1-5 This utility model embodiment provides an automatic cleaning brush assembly for railway turnouts, including a rail 1, and a switching mechanism 2 is provided above the rail 1; The switching mechanism 2 includes a fixed frame 201. Four electric push rods 202 are fixedly connected to the inner wall of the fixed frame 201. A locking block 203 is fixedly connected to the telescopic end of each electric push rod 202. A support frame 204 is located below the fixed frame 201. A screw 205 is rotatably connected inside the fixed frame 201. A movable frame 206 is fixedly connected to the upper surface of the support frame 204. The upper surface of the movable frame 206 contacts the bottom surface of the fixed frame 201. The inner wall of the movable frame 206 is threadedly connected to the outer surface of the screw 205. A servo motor 207 is fixedly connected to the upper surface of the fixed frame 201. The output end of the servo motor 207 and the screw... One end of each rod 205 is fixedly connected to a connecting gear 208, and the two connecting gears 208 mesh with each other. An auxiliary frame 209 is fixedly connected to the upper surface of the support frame 204. Two limiting cylinders 210 are fixedly connected to the upper surface of the fixed frame 201. An auxiliary rod 211 is slidably connected inside each of the two limiting cylinders 210. One end of each of the two auxiliary rods 211 is fixedly connected to one side of the auxiliary frame 209. The auxiliary frame 209 can help the moving frame 206 to support the fixed frame 201 more stably. At the same time, by using the auxiliary rods 211 to slide inside the limiting cylinders 210, the stability and reliability of the support frame 204 during translation can be improved.

[0017] Please refer to this carefully. Figure 2 and Figure 5 The switching mechanism 2 is internally equipped with a cleaning assembly 3, which includes a support plate 301. The bottom surface of the support plate 301 is fixedly connected to the upper surface of the support frame 204. Four rotating shafts 302 are rotatably connected inside the support plate 301. A brush disc 303 is fixedly connected to the bottom end of each rotating shaft 302. The bottom surface of each brush disc 303 is in contact with the upper surface of the rail 1. A dual-axis motor 304 is fixedly connected to the upper surface of the support plate 301. The two output ends of the dual-axis motor 304 are connected to transmission rods 305 through bevel gears. Each transmission rod 305 is connected to the rotating shaft 302 through bevel gears. The support frame 204 has two rotatably connected roller frames 306 inside. The outer surfaces of the two roller frames 306 are in contact with the outer surface of the rail 1. The power provided by the dual-axis motor 304, together with the support plate 301, can drive the rotating shaft 302 to rotate through the bevel gear on the transmission rod 305, thereby causing the brush disc 303 to rotate. At this time, the rotation of the brush disc 303 can realize the automatic cleaning of the railway turnout. Furthermore, the rotation of the roller frames 306 can ensure that the device can move smoothly on the rail 1, making it convenient for workers to directly push the device or use traction and pushing equipment to drive the device.

[0018] Please refer to this carefully. Figure 3 and Figure 4Two batteries 307 are fixedly connected to the upper surface of the support plate 301. Each electric push rod 202, servo motor 207 and dual-axis motor 304 are electrically connected to the battery 307 through wires. The battery 307 can provide the electric push rod 202, servo motor 207 and dual-axis motor 304 with the power required for operation, ensuring that the electric push rod 202, servo motor 207 and dual-axis motor 304 can work normally.

[0019] Please refer to this carefully. Figure 3 and Figure 4 Two shields 308 are fixedly connected to the upper surface of the support plate 301. Each rotating shaft 302 and two transmission rods 305 are located inside the shield 308. The shield 308 can block the bevel gear meshing position between the transmission rod 305 and the rotating shaft 302, preventing external impurities from affecting the power transmission between the transmission rod 305 and the rotating shaft 302.

[0020] Please refer to this carefully. Figure 4 Two positioning plates 309 are fixedly connected to the inner walls of the two shields 308. Each positioning plate 309 is rotatably connected to the transmission rod 305. The bottom surface of each positioning plate 309 is fixedly connected to the upper surface of the support plate 301. The positioning plates 309 can position the transmission rod 305, increasing the rotational stability and reliability of the transmission rod 305.

[0021] When using this utility model: First, connect the electric push rod 202, servo motor 207, dual-axis motor 304 and battery 307 to an external controller. When it is necessary to clean the railway turnout, the power provided by the dual-axis motor 304, in conjunction with the support plate 301, can drive the rotating shaft 302 to rotate through the bevel gear on the transmission rod 305, thereby causing the brush disk 303 to rotate. At this time, the rotation of the brush disk 303 can be used to realize the automatic cleaning of the railway turnout. Furthermore, the rotation of the roller frame 306 can ensure that the device can move smoothly on the rail 1, making it convenient for workers to directly push the device, or to use traction equipment and pushing equipment to drive the device. When it is necessary to clean the rail 1 on an adjacent but not connected railway turnout, the electric push rod 202, in conjunction with the fixed frame 201, pushes the locking block 203 downward until the locking block 203 locks the rail 1. Then, as the electric push rod 202 continues to extend, the moving frame 206, in conjunction with the screw 205 and the auxiliary frame 209, in conjunction with the limiting cylinder 210 and the auxiliary rod 211, lifts the support plate 301 upward until the brush plate 303 and the roller frame 306 disengage from the rail 1. At this time, the power provided by the servo motor 207, in conjunction with the meshing of the two connecting gears 208, drives the screw 205 to start rotating. As the screw 205 rotates, the moving frame 206, in conjunction with the auxiliary frame 209 and the auxiliary rod 211, pushes the support plate 301 above the rail 1 of another railway turnout. At this time, because the U-shaped locking block 203 can firmly lock the rail 1, the support plate 301 will not tilt. Finally, the electric push rod 202 retracts, causing the support plate 301 to move downwards until the roller frame 306 and brush disc 303 contact the rail 1 on another railway turnout. Then, the electric push rod 202 retracts again, disengaging the locking block 203 from the rail 1. Since the center of gravity is now on the support plate 301, the locking block 203 can smoothly disengage from the rail 1, and the fixed frame 201 will not tip over. Then, the servo motor 207 rotates in the opposite direction, driving the moving frame 206 and auxiliary frame 209 to reset, causing the fixed frame 201 to return to the support plate 301. Above 01, the track switching of the automatic turnout cleaning brush assembly can be completed, allowing the automatic turnout cleaning operation to proceed smoothly. At the same time, the automatic turnout cleaning brush assembly can be easily and quickly moved to another unconnected track for turnout cleaning. When there are many railway tracks, it is not necessary to use multiple automatic turnout cleaning brush assemblies for cleaning or to use a crane to switch the tracks of the automatic turnout cleaning brush assembly, which increases the cleaning convenience of the automatic turnout cleaning brush assembly for different tracks.
