[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention provides an intelligent cleaning robot for railway track bed, the structure of which is as follows: Figure 1 - Figure 3 As shown, it includes a moving mechanism 1 and a cleaning mechanism 2.

[0021] The mobile mechanism 1 includes a vehicle body 11 and pulleys 12 disposed on both sides of the vehicle body 11 . A plurality of pulleys 12 are provided with tracks 13 . The vehicle body 11 is provided with a first driving assembly 14 for driving the pulleys 12 to rotate.

[0022] The cleaning mechanism 2 includes a conveyor belt 21 arranged at the bottom of the vehicle body 11, and a second driving component 22 for driving the conveyor belt 21 to rotate is provided on the vehicle body 11. A plurality of electromagnet bars 23 are provided on the conveyor belt 21 at intervals along the length direction of the conveyor belt 21, and the plurality of electromagnet bars 23 are all connected to the output end of the power supply. A receiving tray 24 is provided at the rear of the vehicle body 11 below the conveyor belt 21.

[0023] When in use, the first drive assembly 14 is started to drive the pulleys 12 on both sides of the vehicle body 11 to rotate. The rotation of the pulley 12 causes the crawler 13 to move on the roadbed, thereby realizing the movement of the robot on the roadbed. The second drive assembly 22 is started to drive the conveyor belt 21 to rotate. When the conveyor belt 21 rotates, a plurality of electromagnet bars 23 arranged at intervals thereon pass through the roadbed surface in sequence. Since the electromagnet bars 23 are independently connected to the output end of the power supply, when the electromagnet bars 23 are energized, a strong magnetic field is generated. Iron debris in the railway roadbed, such as iron nails, iron wires, iron filings, etc., are adsorbed onto the electromagnet bars 23 under the action of the magnetic field of the electromagnet bars 23. As the conveyor belt 21 continues to rotate, the electromagnet bars 23 adsorbed with iron debris transport the debris to the rear of the vehicle body 11. At the rear of the vehicle body 11, the receiving tray 24 located below the conveyor belt 21 receives the iron debris falling from the electromagnet bars 23. When the electromagnet bar 23 is powered off, the adsorbed iron debris loses its magnetic restraint and falls into the receiving tray 24 under the action of gravity.

[0024] In the present invention, through the magnetic field adsorption effect of the electromagnet bar 23, the iron debris in the railway track bed can be quickly and effectively cleaned. A plurality of electromagnet bars 23 are arranged at intervals on the conveyor belt 21 and are independently connected to the power supply. When the electromagnet bar 23 moves to the receiving tray 24, the power supply is disconnected, and the metal debris on the electromagnet bar 23 falls onto the receiving tray 24, thereby achieving continuous cleaning and improving the cleaning efficiency.

[0025] In order to drive the crawler 13 to rotate, please refer to Figure 1 In a preferred embodiment, the first driving component 14 includes a solar panel 141 and a first motor arranged on the vehicle body 11, the output end of the solar panel 141 is connected to the input end of the power supply, the first motor is connected to the output end of the power supply, and the output shaft of the first motor is connected to the pulley 12.

[0026] When in use, when sunlight shines on the solar panel 141, the photovoltaic cells in the solar panel 141 convert solar energy into electrical energy. The output end of the solar panel 141 is connected to the input end of the power supply, and the generated electrical energy is transmitted to the power supply for storage. As the solar panel 141 continues to receive light and generate electrical energy, the power supply is continuously charged, and the stored electrical energy will be used to power the various components of the robot. The first motor is connected to the output end of the power supply and starts to operate after obtaining electrical energy from the power supply. The output shaft of the first motor is connected to the pulley 12, and the rotation of the motor drives the pulley 12 to rotate. The tracks 13 on the multiple pulleys 12 start to move driven by the pulleys 12. The tracks 13 are in contact with the surface of the roadbed, and the robot moves forward or backward on the surface of the roadbed through the action of friction.

[0027] In order to limit the position of the vehicle body 11, please refer to Figure 2In a preferred embodiment, the front and rear ends of the vehicle body 11 are provided with a limit assembly 3, and the limit assembly 3 includes a rotating rod 31 rotatably connected to the vehicle body 11, and both ends of the rotating rod 31 are provided with limit wheels 32, and the two sides of the two limit wheels 32 that are close to each other are provided with limit plates 33, and the limit plates 33 are used to abut against the inner side of the rail.

[0028] When in use, when the intelligent cleaning robot starts to move on the railway track bed, as the car body 11 moves, the limiting wheels 32 at both ends of the rotating rod 31 contact the rails and roll on the rails. Since the rotating rod 31 is rotatably connected to the car body 11, the rolling of the limiting wheels 32 will drive the rotating rod 31 to rotate accordingly. When the limiting wheel 32 rolls on the rail, the limiting plate 33 on the limiting wheel 32 gradually approaches the inner side of the rail. As the car body 11 continues to move, the limiting plate 33 finally abuts against the inner side of the rail. After the limiting plate 33 abuts against the inner side of the rail, it plays a limiting role on the car body 11. On the one hand, it limits the movement of the car body 11 in the width direction of the rail, prevents the robot from deviating from the rail during the movement, and ensures that the robot always performs cleaning operations on the track bed between the rails. On the other hand, when the robot encounters external interference, the contact between the limiting plate 33 and the rail can provide a certain support force to maintain the stability of the car body 11 and prevent the car body 11 from overturning or shaking too much.

[0029] In order to adapt the vehicle body 11 to tracks of different widths, please refer to Figure 2 In a preferred embodiment, the rotating rod 31 includes a first rod body 311 and a second rod body 312 slidably connected to both ends of the first rod body 311, the limiting wheel 32 is arranged at the end of the second rod body 312, and the first rod body 311 is provided with an adjustment component 4 for adjusting the distance between the two second rod bodies 312.

[0030] When in use, after the adjustment component 4 is started, it starts to apply force to the second rod body 312 at both ends of the first rod body 311. With the action of the adjustment component 4, the second rod body 312 slides at both ends of the first rod body 311. Since the limiting wheel 32 is arranged at the end of the second rod body 312, when the second rod body 312 moves, the position of the limiting wheel 32 also changes accordingly. In this way, the distance between the limiting wheel 32 and the rail, and the distance between the two limiting wheels 32 can be adjusted. When encountering rails of different widths, the spacing between the two second rod bodies 312 can be adjusted by adjusting the adjustment component 4, so that the limiting plate 33 on the limiting wheel 32 can accurately abut against the inner side of the rail. Ensure that the robot can stably travel and perform cleaning operations on rails of different widths.

[0031] To adjust the distance between the two second rods 312, please refer to Figure 2In a preferred embodiment, the adjustment assembly 4 includes a double-ended screw rod 41 rotatably connected to the first rod body 311 , and both ends of the double-ended screw rod 41 are respectively threadedly connected to the two second rod bodies 312 .

[0032] When in use, the operator rotates the double-headed screw 41. The double-headed screw 41 is rotatably connected to the first rod body 311 and can rotate freely on the first rod body 311. The two ends of the double-headed screw 41 are respectively threadedly connected to the two second rod bodies 312. When the double-headed screw 41 rotates, due to the action of the thread, a thrust or a pull is generated on the two second rod bodies 312. Under the push or pull of the double-headed screw 41, the two second rod bodies 312 slide on the first rod body 311. After the adjustment is completed, the position of the double-headed screw 41 is relatively fixed, and due to the self-locking effect of the thread, the spacing between the two second rod bodies 312 will also remain stable. In this way, it can be ensured that during the operation of the robot, the limiting wheel 32 and the limiting plate 33 can continue to stably play the limiting and guiding role, and will not easily change position due to external force or vibration.

[0033] To reduce the possibility of the double-ended screw 41 rotating loose, please refer to Figure 2 In a preferred embodiment, the double-headed screw rod 41 is provided with an anti-loosening gear 42 , and the first rod body 311 is provided with a slot 43 , in which an anti-loosening tooth block 44 meshing with the anti-loosening gear 42 is clamped.

[0034] During use, when the distance between the two second rod bodies 312 needs to be adjusted, the operator starts to rotate the double-headed screw 41. When the desired distance is adjusted, the operator stops rotating the double-headed screw 41. At this time, due to the meshing action of the anti-loosening gear 42 and the anti-loosening tooth block 44, the double-headed screw 41 is locked and cannot be easily rotated. When the double-headed screw 41 tends to loosen, the anti-loosening gear 42 will be resisted by the anti-loosening tooth block 44, preventing it from rotating. The double-headed screw 41 is effectively prevented from accidentally rotating due to vibration, external force and other factors during the operation of the robot, thereby maintaining the stability of the distance between the two second rod bodies 312.

[0035] To drive the conveyor belt 21 to move, please refer to Figure 3 In a preferred embodiment, the second driving assembly 22 includes a second motor 221 disposed on the vehicle body 11 , a sprocket 222 is disposed on the output shaft of the second motor 221 , and a chain 223 meshing with the sprocket 222 is disposed on the inner side of the conveyor belt 21 .

[0036] When in use, the second motor 221 is connected to the output end of the power supply, and starts to operate after obtaining electric energy from the power supply. The output shaft of the second motor 221 starts to rotate. As the output shaft of the second motor 221 rotates, the sprocket 222 on the output shaft also starts to rotate. A chain 223 meshing with the sprocket 222 is provided on the inner side of the conveyor belt 21. The rotation of the sprocket 222 drives the chain 223 to move through the meshing action. Since the chain 223 is connected to the conveyor belt 21, the movement of the chain 223 drives the conveyor belt 21 to start rotating.

[0037] In order to clean the impurities on the conveyor belt 21 and the electromagnet bar 23, please refer to Figure 3 In a preferred embodiment, a support rod 5 is provided on the vehicle body 11, and a cleaning roller 51 is rotatably connected to the support rod 5. An elastic component 6 is provided on the support rod 5 for making the cleaning roller 51 movably contact the bottom of the conveyor belt 21 and the electromagnet bar 23, and the diameter of the cleaning roller 51 is greater than the spacing between adjacent electromagnet bars 23.

[0038] When in use, when the robot is not started or the cleaning operation is not performed, the cleaning roller 51 is in the initial position under the action of the elastic component 6, and maintains a certain contact pressure or a slight gap with the conveyor belt 21 and the bottom of the electromagnet bar 23. The elastic component 6 is in a compressed or compressed pre-tightened state, ready to apply elastic force to the cleaning roller 51. When the intelligent cleaning robot starts the cleaning mechanism 2 and the second motor 221 drives the conveyor belt 21 to rotate, the electromagnet bar 23 moves with the conveyor belt 21. Since the diameter of the cleaning roller 51 is larger than the spacing between adjacent electromagnet bars 23, and under the action of the elastic component 6, the cleaning roller 51 is movable against the conveyor belt 21 and the bottom of the electromagnet bar 23. As the conveyor belt 21 rotates, the cleaning roller 51 also begins to rotate on the support rod 5. The elastic component 6 applies a continuous elastic force to the cleaning roller 51, so that the cleaning roller 51 always maintains close contact with the conveyor belt 21 and the bottom of the electromagnet bar 23. Even when the conveyor belt 21 and the electromagnet bar 23 change position due to vibration, deformation and other factors during operation, the elastic component 6 can automatically adjust the position of the cleaning roller 51 to ensure the stability of the contact pressure. When the conveyor belt 21 drives the electromagnet bar 23 to pass through the cleaning roller 51, the cleaning roller 51 cleans the bottom of the electromagnet bar 23 and the surface of the conveyor belt 21. The rotation of the cleaning roller 51 scrapes off the non-ferrous debris adsorbed on the bottom of the electromagnet bar 23 and the conveyor belt 21.

[0039] In order to make the cleaning roller 51 always abut against the conveyor belt 21 and the electromagnet bar 23, please refer to Figure 3In a preferred embodiment, the elastic component 6 includes a connecting rod 61 slidably connected to the support rod 5, the cleaning roller 51 is rotatably connected to the connecting rod 61, and a spring is sleeved on the support rod 5, one end of the spring is connected to the support rod 5, and the other end of the spring is connected to the connecting rod 61. The spring is in a compressed state, and the spring causes the cleaning roller 51 to have a tendency to slide toward the conveyor belt 21.

[0040] When in use, when the intelligent cleaning robot starts the cleaning mechanism 2 and the second motor 221 drives the conveyor belt 21 to rotate, the electromagnet bar 23 moves with the conveyor belt 21. As the conveyor belt 21 rotates, the cleaning roller 51 gradually approaches the bottom of the conveyor belt 21 and the electromagnet bar 23 under the tension of the spring. When the cleaning roller 51 contacts the bottom of the conveyor belt 21 and the electromagnet bar 23, the compressed state of the spring continues to provide a certain pressure, so that the cleaning roller 51 is closely abutted against the bottom of the conveyor belt 21 and the electromagnet bar 23. During the cleaning operation, the spring is always in a compressed state and continues to apply tension to the connecting rod 61. The connecting rod 61 transmits this tension to the cleaning roller 51, so that the cleaning roller 51 always maintains contact pressure with the bottom of the conveyor belt 21 and the electromagnet bar 23. Even when the position of the conveyor belt 21 and the electromagnet bar 23 changes due to vibration, deformation or encountering debris of different thicknesses during the working process, the elasticity of the spring can automatically adjust the position of the cleaning roller 51 to ensure the stability of the contact pressure.

[0041] To improve cleaning performance, please refer to Figure 3 In a preferred embodiment, the support rod 5 is arranged at an angle.

[0042] When in use, the inclined support rod 5 makes the cleaning roller 51 more comprehensive and efficient in cleaning the conveyor belt 21 and the bottom of the electromagnet bar 23. During the rotation process, the cleaning roller 51, in addition to scraping off the non-ferrous debris at the bottom of the electromagnet bar 23 and the surface of the conveyor belt 21, can better push the debris to move in a specific direction due to the component force generated by its inclination angle along the moving direction of the conveyor belt 21, and prevent the debris from accumulating around the cleaning roller 51. The contact angle between the cleaning roller 51 and the conveyor belt 21 is more consistent with the moving direction of the conveyor belt 21, reducing the resistance of the cleaning roller 51 to the movement of the conveyor belt 21. This helps the conveyor belt 21 to run smoothly, reduces the load of the motor, and improves the working efficiency and stability of the entire cleaning mechanism 2.

[0043] In order to better understand the present invention, the following Figure 1 - Figure 3The working principle of the technical solution of an intelligent cleaning robot applied to a railway track bed of the present invention is described in detail: the first driving component 14 is started to drive the pulleys 12 on both sides of the vehicle body 11 to rotate. The rotation of the pulley 12 causes the crawler 13 to move on the track bed, thereby realizing the movement of the robot on the track bed. The second driving component 22 is started to drive the conveyor belt 21 to rotate. When the conveyor belt 21 rotates, a plurality of electromagnet bars 23 arranged at intervals thereon pass through the track bed surface in sequence. Since the electromagnet bar 23 is independently connected to the output end of the power supply, when the electromagnet bar 23 is energized, a strong magnetic field is generated. Iron debris in the railway track bed, such as iron nails, iron wires, iron filings, etc., are adsorbed onto the electromagnet bar 23 under the action of the magnetic field of the electromagnet bar 23. As the conveyor belt 21 continues to rotate, the electromagnet bar 23 adsorbed with iron debris transports the debris to the rear of the vehicle body 11. At the rear of the vehicle body 11, the receiving tray 24 located below the conveyor belt 21 receives the iron debris falling from the electromagnet bar 23. When the electromagnet bar 23 is powered off, the adsorbed iron debris loses its magnetic restraint and falls into the receiving tray 24 under the action of gravity.

[0044] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
