Description

Technical Field

[0001] This utility model relates to the field of window cleaning machine technology, and in particular to a single-section telescopic arm column lifting window cleaning machine. Background Technology

[0002] In the modern construction industry, with the increasing number of high-rise buildings and the growing complexity of architectural designs, glass curtain walls, as an important component of building facades, face increasingly severe challenges in cleaning and maintenance. The cleaning quality of glass curtain walls not only directly affects the overall aesthetics of the building but is also closely related to its service life, indoor lighting effects, and the comfort of the living or office environment. Therefore, efficient, safe, and stable window cleaning equipment has become a key requirement in the field of building maintenance.

[0003] While existing automated window cleaning equipment reduces reliance on manual labor to some extent, it still suffers from numerous technical shortcomings. Firstly, regarding mobility, most automated window cleaning machines have simple base frame designs, typically equipped with only a single set of wheels, lacking auxiliary guidance and stabilizing mechanisms. This makes the equipment prone to drifting on flat ground, and even more difficult to move smoothly on uneven terrain, significantly limiting its operating range and flexibility. Although some equipment incorporates a drive motor, the transmission design between the motor and the wheelset is flawed, resulting in unstable power output and high energy consumption, further impacting the equipment's mobility.

[0004] Meanwhile, in terms of structural stability and operational adaptability, the existing window cleaning machine's boom and column connection structure is poorly designed. Most fixed booms and columns are rigidly connected, making it impossible to achieve horizontal rotation adjustment. When cleaning the corners and curved areas of the building facade, the equipment is difficult to adjust the working angle and can only change the working position by moving the entire machine, which is cumbersome and inefficient.

[0005] Therefore, it is necessary to design a single-section telescopic arm column lifting window cleaning machine to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a single-section telescopic boom column lifting window cleaning machine. This invention improves the accuracy of movement by optimizing the base frame moving wheel set and drive structure. Combined with the adjustable boom and inclined beam horizontal angle and reasonable guide wheel layout, it expands the working range, improves cleaning efficiency, and reduces energy consumption and maintenance costs, thus meeting the needs of high-rise building glass curtain walls for efficient, safe and stable cleaning.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A single-section telescopic arm lifting window cleaning machine includes a base frame, an outer column at the upper end of the base frame, an inner column installed inside the outer column, a rectangular opening on the base frame, a through opening at the lower end of the inner column, a fixed arm at the upper end of the inner column, and multiple sets of movable wheels at the lower end of the base frame. Each set of movable wheels includes a fixed column fixedly connected to the base frame, a mounting frame fixedly connected to the lower end of the fixed column, movable wheels installed inside the mounting frame, and multiple auxiliary wheels symmetrically installed at the lower end of the mounting frame. Movable motors are installed on the left side of the two mounting frames on the right side, and the output shafts of the two movable motors are fixedly connected to the rotating shafts of the corresponding movable wheels.

[0009] Preferably, a disc is fixedly connected to the lower end of the outer column, the disc is rotatably connected to the upper end of the base frame, a first gear is fixedly connected to the upper end of the base frame, a first servo motor is mounted on the disc, the output shaft of the first servo motor passes through the disc and is fixedly connected to a second gear, and the second gear meshes with the first gear.

[0010] Preferably, a counterweight box is installed on the left side of the fixed arm, a lifting box is installed on the front side of the outer column, a second pulley group is installed on the upper end of the inner column, and a first pulley group is provided on the adjacent sides of the fixed arm and the counterweight box.

[0011] Preferably, a fixing frame is installed on the right side of the fixing arm, and an inclined beam is provided at the upper end of the fixing frame, with a crossbeam fixedly connected to the upper end of the inclined beam.

[0012] Preferably, a fixing ring is fixedly connected to the upper end of the fixing frame, a toothed ring is rotatably connected inside the fixing ring, the toothed ring is fixedly connected to the lower end of the inclined beam, a second servo motor is installed at the lower end of the fixing frame, and the output shaft end of the second servo motor passes through the fixing frame and is fixedly connected to a third gear that meshes with the toothed ring.

[0013] Preferably, the inclined beam and the crossbeam are integrally formed, both of which are made of hollow steel pipes. The front and rear sides of the crossbeam are equipped with first guide wheels, the inclined beam is inclinedly installed with second guide wheels, the inclined beam is installed with third guide wheels, the fixed frame is installed with fourth guide wheels, and the upper end of the fixed frame is provided with a through hole.

[0014] Compared with existing technologies, the advantages of this device are:

[0015] 1. Compared with the existing technology, the base frame of this device is not only equipped with multiple sets of moving wheels, but also has auxiliary wheels added to the sets of moving wheels. The right mounting frame is equipped with a moving motor to directly drive the moving wheels. The auxiliary wheels can improve the stability of movement and avoid deviation. The direct transmission between the motor and the wheel set ensures stable power output, which greatly improves the accuracy and flexibility of the equipment moving on the track and effectively expands the working range.

[0016] 2. Compared with the existing technology, this device uses the operation of the first servo motor to drive the horizontal angle of the outer column, inner column and fixed arm to adjust. At the same time, it cooperates with the meshing transmission of the second servo motor and the third gear at the lower end of the fixed frame to realize the precise angle adjustment of the inclined beam driving the crossbeam, which can adapt to the cleaning needs of special areas such as building corners and arcs.

[0017] 3. Compared with existing technologies, the rational layout of the first guide wheels on the front and rear sides of the crossbeam, the second and third guide wheels in the inclined beam, the fourth guide wheel in the fixed frame, and the through holes forms a complete guiding path, ensuring that the cleaning rope does not tangle or fall off during the oblique and lateral transmission process, ensuring that the cleaning mechanism moves smoothly along the crossbeam and inclined beam, and further improving cleaning efficiency.

[0025] 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.

[0026] Reference Figures 1-6 A single-section telescopic arm lifting window cleaning machine includes a base frame 1. An outer column 13 is located at the upper end of the base frame 1, and an inner column 4 is installed inside the outer column 13. A rectangular opening is provided on the base frame 1, and the lower end of the inner column 4 passes through the opening. A fixed arm 7 is installed at the upper end of the inner column 4. Multiple sets of movable wheels 2 are installed at the lower end of the base frame 1. Each set of movable wheels 2 includes a fixed column fixedly connected to the base frame 1, and a mounting frame fixedly connected to the lower end of the fixed column. Movable wheels are installed inside the mounting frame, and multiple auxiliary wheels are symmetrically installed at the lower end of the mounting frame. Movable motors 3 are installed on the left side of the two mounting frames on the right side. The output shafts of the two movable motors 3 are fixedly connected to the rotating shafts of the corresponding movable wheels. Through the movable wheel sets 2, the window cleaning machine can move stably on a track (curved track), thereby adjusting the position of the window cleaning machine.

[0027] The lower end of the outer column 13 is fixedly connected to a disc, which is rotatably connected to the upper end of the base frame 1. The upper end of the base frame 1 is fixedly connected to a first gear 12, and a first servo motor 17 is mounted on the disc. The output shaft of the first servo motor 17 passes through the disc and is fixedly connected to a second gear 18. The second gear 18 meshes with the first gear 12. Through the first gear 12 and the second gear 18, the fixed arm 7 can be rotated to make a wide range of adjustments to the position of the subsequent window cleaning components.

[0028] The fixed arm 7 has a counterweight box 6 installed on its left side, the outer column 13 has a lifting box 5 installed on its front side, the inner column 4 has a second pulley block 19 installed on its upper end, and the fixed arm 7 and the counterweight box 6 are each provided with a first pulley block 16 on their adjacent sides.

[0029] A fixing frame 8 is installed on the right side of the fixing arm 7. An inclined beam 9 is provided at the upper end of the fixing frame 8. A crossbeam 10 is fixedly connected to the upper end of the inclined beam 9. A fixing ring 11 is fixedly connected to the upper end of the fixing frame 8. A gear ring 24 is rotatably connected inside the fixing ring 11. The gear ring 24 is fixedly connected to the lower end of the inclined beam 9. A second servo motor 23 is installed at the lower end of the fixing frame 8. The output shaft of the second servo motor 23 passes through the fixing frame 8 and is fixedly connected to a third gear 25 that meshes with the gear ring 24. The engagement of 5 and the toothed ring 24 allows for slight adjustments to the positions of the inclined beam 9 and the crossbeam 10, resulting in more precise adjustments to the position of the window cleaning components. The inclined beam 9 and the crossbeam 10 are integrally formed and are both made of hollow steel pipes. The front and rear sides of the crossbeam 10 are equipped with first guide wheels 15, the inclined beam 9 is inclined with second guide wheels 20, the inclined beam 9 is installed with third guide wheels 21, and the fixed frame 8 is installed with fourth guide wheels 22. The upper end of the fixed frame 8 is provided with a through hole.

[0030] The functional principle of this utility model can be explained through the following operation: When it is necessary to adjust the overall working position of the equipment, the moving motors 3 on the two mounting brackets on the right side of the base frame 1 are started. The output shaft of the moving motor 3 directly drives the rotating shaft of the corresponding moving wheel to rotate, driving the moving wheel to roll along the working track (or the ground); at the same time, the auxiliary wheels symmetrically arranged at the lower end of the mounting bracket in the moving wheel group 2 roll synchronously in contact with the track (or the ground). On the one hand, the stability of the equipment during movement is improved by supporting multiple wheels, avoiding deviation caused by uneven force on a single wheel. On the other hand, the auxiliary wheels can guide the direction of movement, ensuring that the equipment moves smoothly along the preset path, and finally achieving precise position adjustment of the equipment in the horizontal direction to meet the cleaning and coverage needs of different areas.

[0031] If it is necessary to change the overall working direction of the fixed arm 7, inclined beam 9, and crossbeam 10 (such as turning from the front of the building to the side), start the first servo motor 17 on the disc at the lower end of the outer column 13. The output shaft of the first servo motor 17 drives the second gear 18 to rotate. Since the second gear 18 meshes with the first gear 12 fixed at the upper end of the base frame 1, and the disc is rotatably connected to the base frame 1, the rotation of the second gear 18 will drive the disc to drive the outer column 13, inner column 4, and the upper fixed arm 7, counterweight box 6, fixed frame 8, and other structures to rotate around the center of the base frame 1. Until the target working angle is adjusted, the working direction of the equipment can be flexibly switched. When fine-tuning is required, the working angle of the crossbeam 10 needs to be adjusted. The second servo motor 23 at the lower end of the fixed frame 8 is started. The output shaft of the second servo motor 23 drives the third gear 25 to rotate. The third gear 25 meshes with the toothed ring 24 rotatably connected inside the fixed ring 11. The toothed ring 24 is fixed to the lower end of the inclined beam 9, thereby driving the toothed ring 24 to drive the inclined beam 9 and the upper crossbeam 10 to rotate around the center of the fixed ring 11, so that the cleaning mechanism on the crossbeam 10 can fit against the glass curtain wall.

[0032] During cleaning operations, the cleaning mechanism (such as a cleaning brush or a cleaning suction cup) is installed on the crossbeam 10. One end of the cleaning rope is connected to the cleaning mechanism, and the other end passes sequentially through the first guide wheel 15 on the front and rear sides of the crossbeam 10, the second guide wheel 20 inside the inclined beam 9, the third guide wheel 21 inside the inclined beam 9, and the fourth guide wheel 22 inside the fixed frame 8. The first pulley group 16 and the second pulley group 19 are connected to the lifting box 5 (or an independent drive assembly). After the drive assembly is started, the rope is driven along the complete path formed by the above-mentioned guide wheels, driving the cleaning mechanism to move back and forth along the crossbeam 10 or tilt along the inclined beam 9. The guide wheels ensure that the rope does not tangle or fall off during the transmission process, and always maintains stable tension, so that the cleaning mechanism can evenly conform to the surface of the glass curtain wall and achieve efficient cleaning.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
