[0001] This utility model relates to the field of window cleaning machine technology, specifically a turning-type two-wheel walking mechanism for a window cleaning machine. Background Technology

[0002] Window cleaning machines, as specialized non-standard products for high-altitude operations, have become essential mechanical equipment for transporting workers, equipment, and cleaning tools to clean, maintain, and repair the exterior walls (such as glass, metal sheets, and stone) of high-rise and super high-rise buildings. However, when the window cleaning machine's wheel assembly passes through curves, the difference in travel distance between the inner and outer wheels can easily lead to slippage, wear, and impact problems, significantly increasing the pressure on the track. This negatively impacts the walking mechanism, which serves as the supporting foundation of the entire machine, directly affecting its performance and safety. Therefore, we need to propose a turning-type dual-wheel walking mechanism for window cleaning machines. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides: a turning-type double-wheel walking mechanism for a window cleaning machine, including a mounting base 1, a mounting seat 2, and a sliding table 4 slidably mounted inside the mounting seat 2; the mounting base 2 is connected to the end of the mounting base 1, and a fixed guide rod 3 that cooperates with the sliding table 4 is installed on the inner wall of the mounting seat 2; auxiliary rollers 7 for auxiliary movement adjustment are provided on both sides of the sliding table 4; a shock-absorbing and limiting mechanism is connected to the top of the sliding table 4, and the fixing frame 13 of the shock-absorbing and limiting mechanism is fixedly installed on the top of the mounting base 1; a connecting block 14 is connected to the bottom of the sliding table 4, and a driving wheel 15 is installed inside the connecting block 14; the connecting block 14 is mounted on an arc-shaped track 20 through a track limiting frame 18.

[0020] It is worth noting that, through the coordinated arrangement of the mounting base 2, sliding table 4, auxiliary roller 7, track limit frame 18, and shock absorption limit mechanism, the walking mechanism can be directly driven, the power transmission is direct and efficient, and the spacing of the walking mechanism is limited. This effectively guides and constrains the movement of the walking wheels on the arc path, reduces safety issues such as slippage, wear, and impact, and further improves the stability and smoothness of the equipment when passing through curves, preventing deviation and jamming.

[0021] Specifically, the shock absorption and limiting mechanism includes: a positioning shaft 8 connected to the top of the sliding table 4, and a connecting shaft 12 installed on the top of the fixed frame 13; wherein, a hydraulic rod 9 is movably mounted on the surface of the connecting shaft 12, and a connecting sleeve 10 is connected to the protruding end of the hydraulic rod 9. The connecting sleeve 10 is movably fitted onto the surface of the positioning shaft 8, and a compression spring 11 is movably fitted onto the surface of the hydraulic rod 9 through a limiting plate.

[0022] Among them, the sliding table 4 serves to guide and limit the fixed guide rod 3, the positioning shaft 8 is connected with the connecting sleeve 10 to install the hydraulic rod 9, the connecting shaft 12 is the mounting component for installing the hydraulic rod 9, the fixing bracket 13 is used to install the hydraulic rod 9 in conjunction with the connecting shaft 12, and the compression spring 11 is used in conjunction with the hydraulic rod 9 to remove the adaptive shock absorption function of the sliding table 4, improve the stability of the walking mechanism, and reduce slippage, wear and impact during turning.

[0023] Limiting plates 6 are connected to both sides of the sliding table 4, and auxiliary rollers 7 are embedded in the surface of the limiting plates 6. Limiting guide holes 5 are formed on the surface of the sliding table 4, and the inner wall of the limiting guide holes 5 is slidably connected to the surface of the fixed guide rod 3. A mounting bracket 17 is connected to the side of the connecting block 14, and a drive motor 16 is mounted on the surface of the mounting bracket 17. The output end of the drive motor 16 is connected to the traveling wheel 15.

[0024] In addition, the limiting plate 6 works with the auxiliary roller 7 to provide stable auxiliary guidance for the movement of the sliding table 4, improve the smoothness of operation, and at the same time play a role in limiting and preventing detachment. The mounting frame 17 is a structure for mounting the drive motor 16. The drive motor 16 directly drives the mounting frame 17, improving the stability and smoothness of turning.

[0025] Furthermore, the track limit frame 18 is bolted to both ends of the connecting block 14, and auxiliary wheels 19 are installed at the bottom of the track limit frame 18. The auxiliary wheels 19 are set on both sides of the surface of the arc-shaped track 20. The track limit frame 18 plays a role in restricting and preventing the walking wheels 15 from slipping when they move, thereby improving the stability of the window cleaning machine. The auxiliary wheels 19 are a guide structure that assists in turning. By using the arc-shaped track 20 in conjunction with the auxiliary wheels 19 at the bottom of the track limit frame 18, and in combination with the auxiliary rollers on both sides of the sliding table 4, the movement of the walking wheels 15 on the arc-shaped path is effectively guided and constrained, improving the stability and smoothness of the equipment when passing through curves, and preventing deviation and jamming.

[0026] The shock-absorbing and limiting mechanism, composed of hydraulic rods 9, compression springs 11, and other components, absorbs and mitigates vibrations and impacts generated during equipment movement and operation, protecting the mechanism itself and improving the overall stability of the machine. Simultaneously, it flexibly limits the movement of the sliding table 4, enhancing controllability and safety during operation.

[0027] The sliding table 4, through the precise sliding fit between the limiting guide hole 5 and the fixed guide rod 3, forms the core guiding and load-bearing structure. This ensures that the mechanism has sufficient rigidity and stability when bearing loads, guaranteeing long-term operational reliability. Furthermore, the auxiliary roller 7, in conjunction with the sliding table, reduces wear between the fixed guide rod 3 and the limiting guide hole 5, thereby extending service life.

[0028] The traveling wheels 15 are directly driven by the drive motor 16 and the mounting bracket 17, resulting in direct and efficient power transmission. Meanwhile, the main components, such as the track limit bracket 18, are connected by bolts, which is highly modular and facilitates installation, debugging, and subsequent maintenance and replacement, reducing maintenance costs. Furthermore, the fact that the traveling wheels 15 are driven independently by the drive motor 16 can improve the stability of turning and achieve a smooth turning effect.

[0029] The track limit frame 18 and auxiliary wheels 19 ensure a stable connection between the equipment. The fixed guide rod 3 and the sliding table 4 inside the mounting base 2 work together to allow the sliding table 4 to move and adjust along the fixed guide rod 3 and auxiliary roller 7 when the traveling wheel 15 travels to an arc-shaped turning position, achieving adaptive adjustment and improving the stability and smoothness of the turning. The hydraulic rod 9 and the compression spring 11 on the surface restrict the movement of the sliding table 4, allowing it to adapt to the movement of the window cleaning machine and further reduce safety problems such as slippage, wear and impact, thereby improving the stability and safety of the equipment.

[0030] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
