Description

Technical Field

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

[0002] As modern buildings develop towards high-rise and super high-rise structures, the area of ​​building curtain walls is constantly expanding, leading to increased demands for the cleaning and maintenance of building facades. The requirements for cleaning and maintenance efficiency are also rising, as are the requirements for the overall aesthetic appeal of the building when installing window cleaning machines. Traditional window cleaning machines mostly use fixed boom structures or simple suspended baskets, which still have significant limitations in terms of operating range, extension capacity, flexibility, and maintenance adaptability.

[0003] For high-rise buildings, simply installing window cleaning machines on the rooftop is inefficient. Typically, a new machine is added on an intermediate floor, extending its boom through a curtain wall window to the area below the work surface, thus increasing the efficiency of cleaning and maintenance of the building's facade. Using a linear boom window cleaning machine requires numerous pre-installed windows in the building structure and curtain wall, placing high demands on the building. It also easily creates blind spots, has a large stopping size, is inflexible in floor movement, and occupies significant inter-floor space when stored. Furthermore, some buildings have high-mounted lightning protection devices at the top. If a traditional linear boom window cleaning machine is used, the machine needs to be made quite tall, with the boom height exceeding the lightning protection device, to ensure the machine can clean all areas of the building facade without blind spots. This significantly impacts the overall aesthetic appearance of the building. Summary of the Invention

[0004] Therefore, this utility model provides a telescopic double-folding arm window cleaning machine, which greatly improves operational flexibility and safety, and occupies little space, making it easy to store or hide inside a building.

[0005] To solve the above-mentioned technical problems, this utility model provides a telescopic double-folding arm window cleaning machine, comprising: track; The base frame is movably connected to the track via a traveling mechanism; A main boom slewing mechanism is provided between the column and the base frame; The telescopic assembly includes a fixed boom connected to the upper end of the column and a telescopic boom that is telescopically and adjustablely connected to the fixed boom; A first folding arm is provided with a first folding arm rotation mechanism between itself and the front end of the telescopic boom; The second folding arm is provided with a second folding arm rotation mechanism between its front end and the first folding arm. A material lifting point and a gantry are provided below the second folding arm. The main hoisting mechanism is installed on the column and connected to the gantry via a first steel wire rope. The material lifting mechanism is installed on the fixed boom and connected to the material lifting point via a second steel wire rope.

[0006] In one embodiment of this utility model, the walking mechanism includes a walking wheel that rolls in contact with the top surface of the track, anti-tilt wheels that are close to the two sides of the track, and a driving device that drives the walking wheel to rotate. The axis of the anti-tilt wheel is perpendicular to the axis of the walking wheel.

[0007] In one embodiment of this utility model, the telescopic assembly further includes an adjusting motor installed on the fixed boom. The telescopic boom is movably connected to the inner cavity of the fixed boom along its length. A rack is provided on the bottom wall of the telescopic boom. The output end of the adjusting motor is connected to a gear that meshes with the rack. The rear end of the telescopic boom extends out of the fixed boom and is connected to a counterweight.

[0008] In one embodiment of this utility model, a first guide wheel is provided between the two side walls of the fixed boom and the corresponding side wall of the telescopic boom, and a second guide wheel is provided between the bottom wall and the top wall of the telescopic boom and the fixed boom.

[0009] In one embodiment of this utility model, the main boom slewing mechanism, the first folding boom slewing mechanism, and the second folding boom slewing mechanism all adopt slewing bearings driven by motors.

[0010] In one embodiment of this utility model, the fixed boom is fixed to the upper end of the column via a flange connection, the outer ring of the main boom slewing mechanism is connected to the base frame, and the column is connected to the inner ring of the main boom slewing mechanism.

[0011] In one embodiment of this utility model, the inner ring of the first folding arm slewing mechanism is connected to the front end of the telescopic boom, and the outer ring of the first folding arm slewing mechanism is connected to the tail end of the first folding arm.

[0012] In one embodiment of this utility model, the inner ring of the second folding arm rotation mechanism is fixedly connected to the tail end of the second folding arm, and the outer ring of the second folding arm rotation mechanism is connected to the front end of the first folding arm.

[0013] In one embodiment of this utility model, the front end of the telescopic boom, the interior of the first folding arm, and the interior of the second folding arm are all provided with rope guide rails.

[0014] In one embodiment of this utility model, both the main lifting mechanism and the material lifting mechanism are hoisting mechanisms.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: This utility model describes a telescopic double-folding arm window cleaning machine, which can flexibly adjust its extension direction according to the shape of the curtain wall or the position of the window, improving adaptability and making it easier for the crane to reach the target work area. The fixed arm, in conjunction with the telescopic arm, can be arranged lengthwise inside the building and extends to the exterior facade during operation, overcoming limitations such as limited floor height and small window size. The telescopic arm allows for continuous adjustment of its length, offering flexible operation, precise positioning, and a small footprint. The first folding arm is rotatable relative to the telescopic arm, and the second folding arm is rotatable relative to the first folding arm, making the crane's position adjustment more flexible and adaptable to multi-angle facade structures. This allows for precise positioning of the crane even in narrow curtain wall gaps, greatly improving operational flexibility and safety, while also minimizing space requirements, making it easy to operate, store, or conceal within the building.

Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Reference Figures 1 to 3 As shown, this utility model discloses a telescopic double-folding arm window cleaning machine, comprising: Track 1 is fixed to the concrete foundation support of the building roof; The base frame 2 is movably connected to the track 1 via the walking mechanism 11; the walking mechanism 11 drives the entire machine to move along the track 1. A main boom slewing mechanism 91 is provided between the column 3 and the base frame 2; The telescopic assembly 4 includes a fixed boom 41 connected to the upper end of the column 3 and a telescopic boom 42 that is telescopically and adjustablely connected to the fixed boom 41. A first folding arm 5 is provided with a first folding arm rotation mechanism 92 between it and the front end of the telescopic boom 42; The second folding arm 6 is provided with a second folding arm rotation mechanism 93 between its front end and the front end of the first folding arm 5. The material lifting point 94 and the gantry 95 are provided below the second folding arm 6. The main hoisting mechanism 7 is installed on the column 3 and connected to the gantry 95 via a first steel wire rope. The material lifting mechanism 8 is installed on the fixed boom 41 and is connected to the material lifting point 94 via a second steel wire rope.

[0027] Specifically, the material lifting point 94 is located in the middle of the second folding arm 6 and is suspended below the second folding arm 6 by a second steel wire rope for lifting maintenance materials such as glass panels. The gondola 95 is located at the front end of the second folding arm 6 for workers to clean and maintain the curtain wall.

[0028] In one embodiment, the walking mechanism 11 includes a walking wheel that rolls in contact with the top surface of the track 1, anti-tilt wheels 12 that are close to the two sides of the track 1, and a drive device 13 that drives the walking wheel to rotate. The axis of the anti-tilt wheel 12 is perpendicular to the axis of the walking wheel.

[0029] In one embodiment, the telescopic assembly 4 further includes an adjusting motor 43 mounted on the fixed boom 41. The telescopic boom 42 is movably connected to the inner cavity of the fixed boom 41 along its length. A rack 44 is provided on the bottom wall of the telescopic boom 42. The output end of the adjusting motor 43 is connected to a gear that meshes with the rack 44. The rear end of the telescopic boom 42 extends out of the fixed boom 41 and is connected to a counterweight 45 for balancing the front load. The adjusting motor 43 drives the gear to mesh with the rack 44, thereby achieving smooth, controllable, and continuous adjustment of the telescopic boom.

[0030] In one embodiment, a first guide wheel is provided between the two side walls of the fixed boom 41 and the corresponding side walls of the telescopic boom 42, and a second guide wheel is provided between the bottom and top walls of the telescopic boom 42 and the fixed boom 41. This ensures that the telescopic boom 42 experiences uniform force and smooth movement during extension and retraction, avoids jamming and deviation, and improves the reliability and service life of the telescopic mechanism.

[0031] In one embodiment, the main boom slewing mechanism 91, the first articulated boom slewing mechanism 92, and the second articulated boom slewing mechanism 93 all employ motor-driven slewing bearings. Motor-driven slewing bearings offer advantages such as high torque, high positioning accuracy, and low operating noise. Specifically, the gear on the shaft end of the reduction motor meshes with the slewing bearing gear.

[0032] Specifically, the fixed boom 41 is fixed to the upper end of the column 3 via a flange connection; the outer ring of the main boom slewing mechanism 91 is connected to the base frame 2; the column 3 is connected to the inner ring of the main boom slewing mechanism 91; the inner ring of the first folding boom slewing mechanism 92 is connected to the front end of the telescopic boom 42; the outer ring of the first folding boom slewing mechanism 92 is connected to the tail end of the first folding boom 5; the inner ring of the second folding boom slewing mechanism 93 is fixedly connected to the tail end of the second folding boom 6; and the outer ring of the second folding boom slewing mechanism 93 is connected to the front end of the first folding boom 5.

[0033] In one embodiment, guide rails 46 are provided inside the front end of the telescopic boom 42, the first folding arm 5, and the second folding arm 6. The guide rails 46 ensure smooth and wear-free operation of the wire rope, improving the reliability and durability of the overall structure.

[0034] In one embodiment, both the main hoisting mechanism 7 and the material hoisting mechanism 8 are winch mechanisms.

[0035] This window cleaning machine is primarily used between building floors or on equipment floors. During operation, the traveling mechanism 11 drives the entire machine along track 1 to the vicinity of the target area; the main boom slewing mechanism 91 adjusts the direction of the telescopic boom 42; the telescopic boom 42 extends, extending the folding arm and gondola 95 through the building's pre-reserved window to the outside of the building. Subsequently, the first folding arm slewing mechanism 92 and the second folding arm slewing mechanism 93 adjust the slewing angles of the first folding arm 5 and the second folding arm 6, respectively, so that the gondola 95 reaches the working position outside the curtain wall, keeping its length parallel to the curtain wall facade. The gondola 95 is equipped with anti-collision wall-mounted wheels on both sides, effectively protecting the curtain wall within the ±180° folding arm working range and preventing collisions between the gondola 95 and the curtain wall.

[0036] When a curtain wall unit panel is damaged, the glass unit panel can be safely transported to the damaged location for replacement or repair using material lifting point 94.

[0037] Reference Figure 4 As shown, when the equipment stops, the telescopic boom 42 is first retracted to its shortest state, and then the folding arm is rotated back to below the telescopic boom 42, which significantly shortens the overall boom length, occupies less space, and is convenient for operation, storage or concealment inside the building.

[0038] Finally, the window cleaning machine is moved to the parking area by the walking mechanism 11 to complete the shutdown. It should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and are not intended 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.
