[0014] Figs. 1-2This utility model discloses a large heavy-duty roof rail-mounted window cleaning machine, comprising a rail 1, a traveling mechanism 2 that moves along the rail 1, a base frame 3 mounted on the traveling mechanism 2, a main slewing mechanism 4 mounted on the base frame 3, a column 5 with its bottom fixed to the main slewing mechanism 4, a first hoisting mechanism 6 mounted on one side of the column 5, a main telescopic boom 7 mounted on the top of the column 5, a first movable counterweight 8 mounted on one end of the main telescopic boom 7, and a small slewing mechanism 9 mounted on the other end of the main telescopic boom 7. The output end of the small slewing mechanism 9 is driven to connect to a folding arm head 10, and a telescopic approaching gondola 11 is connected below the folding arm head 10. The first hoisting mechanism 6 is driven to extend or retract the main telescopic boom 7 via a wire rope.
[0015] In use, the walking mechanism 2 moves along the track 1 to the vicinity of the multi-dimensional turning and multi-angle changing wall surface. The main slewing mechanism 4 drives the column 5 to rotate, which in turn drives the first hoisting mechanism 6 and the main telescopic boom 7 to extend the small slewing mechanism 9. The small slewing mechanism 9 drives the folding boom head 10 to rotate, so that the telescopic approaching gondola 11 can approach various multi-dimensional turning and multi-angle changing wall surfaces. This utility model is suitable for cleaning windows on multi-dimensional turning and multi-angle changing wall surfaces where the track 1 is difficult to arrange, and has better applicability.
[0016] The walking mechanism 2 includes a walking housing, a vertical shaft mounted on the walking housing, and two geared motors installed parallel to one side of the walking housing. The output shaft of each geared motor extends into the walking housing and is connected to a drive shaft. A walking wheel is mounted on the drive shaft. The geared motor drives the walking wheel to roll along the track 1 via the drive shaft. The top of the vertical shaft is connected to the base frame 3. In this embodiment, the two geared motors drive the shafts respectively, and the two drive shafts drive the walking wheel to roll along the track 1 respectively.
[0017] The main slewing mechanism 4 includes a large slewing housing 41 fixed on the base frame 3, and a large slewing motor 42 fixed on the large slewing housing 41. The output shaft of the large slewing motor 42 extends into the large slewing housing 41 and is provided with a first driving gear. The bottom end of the column 5 extends into the large slewing housing 41 and is provided with a first driven gear. The first driving gear meshes with the first driven gear. The column 5 is rotatably connected to the large slewing housing 41. In this embodiment, the large slewing motor 42 drives the column 5 to rotate through the first driving gear and the first driven gear, adjusting the direction of extension and retraction towards the gondola 11.
[0018] The small slewing mechanism 9 includes a small slewing housing 91 fixed to the extended end of the main telescopic boom 7, and a small slewing motor 92 fixed to the bottom of the small slewing housing 91. The output shaft of the small slewing motor 92 extends into the small slewing housing 91 and is provided with a second driving gear. A driven shaft is provided on the folding boom head 10. The bottom end of the driven shaft extends into the small slewing housing 91 and is provided with a second driven gear. The second driving gear meshes with the second driven gear. The driven shaft is rotatably connected to the small slewing housing 91. In this embodiment, the small slewing motor 92 drives the driven shaft to rotate through the second driving gear and the second driven gear, adjusting the direction of the extension and retraction of the end of the folding boom head 10 toward the gondola 11.
[0019] The telescopic approaching gondola 11 includes a fixed cantilever 111 connected to the folding boom head 10, a small telescopic cantilever 112 slidably connected to the fixed cantilever 111 at its rear end, a second winch mechanism 113 fixed to the front end of the small telescopic cantilever 112, a fixed suspension point set at the front end of the small telescopic cantilever 112, a gondola body 114 installed at the fixed suspension point, and a second movable counterweight 115 installed on the fixed cantilever 111. The second winch mechanism 113 drives the small telescopic cantilever 112 to extend or retract from the fixed cantilever 111 via a wire rope. In this embodiment, during use, the second winch mechanism 113 drives the small telescopic cantilever 112 to extend or retract from the fixed cantilever 111 via a wire rope. As a further improvement of this utility model, the position of the gondola body 114 is adjusted so that the gondola body 114 can accurately reach the working position.
[0020] The first winch mechanism 6 and the second winch mechanism 113 in this application are both composed of a winch and multiple pulleys. The extension and retraction of the cantilever are achieved by connecting the winch and multiple fixed pulleys with a wire rope. This is a common technology in the prior art, so it will not be described in detail here.
[0021] In operation, the traveling mechanism 2 drives the window cleaning machine to move along the track, the slewing mechanism motor can drive the telescopic boom to rotate ±180 degrees, the telescopic boom can drive the boom to extend and retract, and the working length of the boom can be adjusted. The small slewing mechanism 9 can drive the folding boom head to rotate within a range of ±90 degrees, and make fine adjustments to the telescopic boom approaching the working position of the gondola 11 so that the gondola can accurately reach the working position. Because the front-end suspension of this design is a telescopic boom 11, the total load of the front-end suspension can reach more than 4 tons during operation, resulting in a very heavy self-weight for the window cleaning machine. This necessitates a high load-bearing capacity for the traveling mechanism 2. The traveling mechanism 2 in this design adopts a double-wheel configuration, meaning each traveling mechanism 2 has two wheels. This distributes the force across a single fulcrum, reducing localized stress on the track and lowering the probability of track deformation. Simultaneously, the traveling mechanism 2 is connected to the base frame via a vertical shaft. During travel, the traveling mechanism 2 can rotate relative to the base frame for fine-tuning, preventing jamming caused by slight deviations in track straightness or gauge. During operation, the front-end suspension of the window cleaning machine bears a heavy load. The switching between full load and no load during the telescopic boom's extension and retraction significantly impacts the balance and stability of the window cleaning machine. Therefore, this design uses a movable counterweight. During boom extension and retraction, the counterweight moves in the opposite direction to the boom at a 1:2 ratio, ensuring that the balance ratio of the window cleaning machine fluctuates within an appropriate range, guaranteeing the overall balance and stability of the machine during operation.
[0022] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
