[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 The single-arm, upright window cleaning machine includes a mobile platform 1, which provides the mounting foundation for all components above the machine. Four support legs 2 are fixedly connected to the bottom of the mobile platform 1. Two support legs 2 on the same side are mounted on a guide rail 3, which guides the overall movement of the machine. Each support leg 2 has a moving mechanism, which includes four rectangularly distributed limit wheels rotatably connected to the bottom of the support leg 2. The outer walls of the limit wheels abut against the outer walls of the guide rail 3, limiting the lateral displacement of the support leg 2 along the guide rail 3 to ensure stable movement. A moving motor 4 is fixedly connected to the side wall of the support leg 2. Multiple moving motors 4 are synchronously controlled by a synchronization system to ensure identical output. The moving motor 4 provides the power source for the machine's movement. The output shaft of the moving motor 4 passes through the support leg 2 and is rotatably connected to it. A moving wheel 5 is fixedly connected to the end of the output shaft of the moving motor 4. The moving wheel 5 rotates under the drive of the moving motor 4, causing the machine to move along the guide rail 3. The outer wall of the moving wheel 5 abuts against the top of the guide rail 3.

[0024] A fixed gear 6 is fixedly connected to the top of the mobile platform 1. The fixed gear 6 cooperates with the rotating gear 10 to realize the rotation adjustment of the rotating disk 7. The rotating disk 7 is rotatably connected to the top of the fixed gear 6. The rotating disk 7 can rotate around the axis of the fixed gear 6 to drive the upper component to change the working direction. A rotary motor 9 is fixedly connected to the top of the rotating disk 7. The rotary motor 9 provides power for the rotation of the rotating disk 7. The output shaft of the rotary motor 9 passes through the rotating disk 7 and is rotatably connected to it. The rotating gear 10 is fixedly connected to the end of the output shaft of the rotary motor 9. The rotating gear 10 rotates under the drive of the rotary motor 9 and meshes with the fixed gear 6 for transmission. The fixed gear 6 and the rotating gear 10 mesh.

[0025] A fixed frame 8 is fixedly connected to the top of the rotating disk 7. The fixed frame 8 is used to connect and support the first connecting arm 11 and the second connecting arm 12. The first connecting arm 11 is rotatably connected to the top of the fixed frame 8. The first connecting arm 11 can rotate around the connection point with the fixed frame 8 to realize the extension and retraction adjustment of the working range. The end of the first connecting arm 11 is rotatably connected to the top column 13. The top column 13 is used to support the end component (suspended basket) of the rope 22. The fixed frame 8 and the top column 13 are rotatably connected to the second connecting arm 12. The second connecting arm 12, the first connecting arm 11, the fixed frame 8 and the top column 13 form a parallelogram structure to ensure the horizontal state of the top column 13 when it is raised and lowered. Two hydraulic rods 14 are rotatably connected to the top of the rotating disk 7. The synchronous extension and retraction of the two hydraulic rods 14 is controlled by a synchronous hydraulic circuit. The output ends of the two hydraulic rods 14 are rotatably connected to the side wall of the first connecting arm 11. The hydraulic rods 14 drive the first connecting arm 11 to rotate through extension and retraction to realize the raising and lowering adjustment of the top column 13.

[0026] The second connecting arm 12 is equipped with a winding and releasing mechanism. This mechanism controls the winding and releasing of the rope 22 and adjusts the height of the end basket. The mechanism includes a mounting bracket 15 fixedly connected to the side wall of the second connecting arm 12. A winding motor 16 is fixedly connected to the side wall of the mounting bracket 15, providing power for the winding and releasing of the rope 22. A reducer 17 is fixedly connected to the side wall of the mounting bracket 15, reducing the output speed of the winding motor 16 and increasing the torque to ensure smooth winding and releasing of the rope 22. The winding motor 16 and... The reducer 17 is connected to a winding roller 18, which is rotatably connected to the mounting bracket 15. The winding roller 18 rotates under drive to wind or unwind the rope 22. Two guide wheels 19 are rotatably connected to the second connecting arm 12. The guide wheels 19 change the direction of the rope 22, guiding it to move along a preset path. A pair of first transmission wheels 20 are rotatably connected to the bottom of the top column 13. The first transmission wheels 20 further guide the rope 22 to ensure stable transmission. The bottom of the top column 13 is rotatably connected to... A pair of second drive wheels 21, in conjunction with the first drive wheel 20, keep the rope 22 taut and precisely guide it. The outer wall of the take-up roller 18 is wound with the rope 22, and the end of the rope 22 is suspended from the basket to achieve the lifting and lowering of personnel or tools. One end of the rope 22 is fixedly connected to the outer wall of the take-up roller 18. The rope 22 is wound around the outer wall of two guide wheels 19. The outer wall of the rope 22 abuts against the outer walls of the two first drive wheels 20 and the outer walls of the two second drive wheels 21. A first through-hole is provided on the second connecting arm 12, through which the rope 22 passes. The first through-hole provides a channel for the rope 22 to pass through the second connecting arm 12 to avoid interference between the rope 22 and other components. Two U-frames are installed on the outer wall of the top column 13. The two U-frames are rotatably connected to the ends of the first connecting arm 11 and the second connecting arm 12, respectively. The rope 22 passes through the gap between the U-frames. Since the rope 22 is parallel to the top column 13 and the top column 13 always maintains a horizontal posture when lifting and lowering, it will not affect the movement path of the rope 22.

[0027] In this invention, starting the movable motor 4 causes the movable wheel 5 to rotate via its output shaft. The rotation of the movable wheel 5 allows the device to move on the two guide rails 3, thereby adjusting its position. Starting the rotary motor 9 causes the rotary gear 10 to rotate via its output shaft. The interaction between the rotary gear 10 and the fixed gear 6 allows the rotating disk 7, the fixed frame 8, and the top column 13 to rotate around the axis of the fixed gear 6, thereby adjusting the orientation of the device. Starting the two hydraulic rods 14 drives the first connecting... The arm 11 rotates around the connection point between the first connecting arm 11 and the fixed frame 8. The fixed frame 8, the first connecting arm 11, the second connecting arm 12, and the top column 13 form a parallelogram structure, which allows the top column 13 to rise and fall. The top column 13 remains horizontal during the rise and fall, ensuring the level of the suspended platform. By attaching the suspended platform to the end of the rope 22, workers can sit and clean windows. When it is necessary to adjust the height of the suspended platform, the winding motor 16 is started to drive the winding roller 18 to rotate, thereby winding or unwinding the rope 22, so as to adjust the height of the suspended platform connected to the end of the rope 22.
