Description

Technical Field

[0001] The utility model relates to the technical field of window cleaning machines, in particular to a window cleaning machine with a telescopic boom having the functions of lying down and a column pitching and lifting. Background Art

[0002] With the development of the national economy and the continuous expansion of urban planning, high-rise buildings are increasingly appearing. Window cleaning machines, specialized equipment for cleaning and maintaining high-rise building exteriors, have gained widespread recognition among construction companies, architects, and curtain wall contractors, becoming a permanent fixture in high-rise buildings and a hallmark of their advanced character. It's often said that architecture is like frozen music. China is vigorously promoting urbanization, and a wave of unique, innovative, and visually striking high-rise buildings is emerging. In this process, window cleaning machines must meet the demands of daily exterior wall cleaning and maintenance while minimizing impact on the overall appearance of the building facade, placing higher demands on their placement and concealment.

[0003] Window cleaning machines, as permanent, specialized equipment for cleaning and maintaining high-rise building facades and skylight roofs, require different designs based on the building's height, facade and roof structure, load capacity, and available space for the equipment to operate. Safety, cost-effectiveness, and practicality must be considered, as well as ensuring the installed machine's compatibility with the building and its aesthetics. This requires domestic window cleaning machine manufacturers to continuously improve their technology, be innovative, and absorb advanced international technologies and experience to design equipment that is both safe and economical, while also adapting to the building's appearance.

[0004] When the existing window cleaning machine is not in operation, the boom cannot be stopped by lying down at 45 degrees, so that the window cleaning machine cannot be hidden in the building curtain wall, which affects the aesthetics of the building. Secondly, the stability and firmness of the boom during operation are poor, which easily causes the arm head to swing up and down, thereby making the manned platform suspended by steel wires below the arm head less stable and comfortable. In addition, it cannot adapt to the different heights of buildings, meet the requirements of various structural forms of facades and the size of the cleaning area, and the balance arm is usually long, so that the rotation occupies a large space, which is not conducive to achieving the hiding function in areas with limited activity space. Therefore, there is an urgent need for a window cleaning machine with a retractable boom with lying down, column pitching, and lifting functions to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a window cleaning machine with a telescopic boom and the functions of lying down, pitching and lifting of the column, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A window cleaning machine with a retractable boom with the functions of lying down, pitching and lifting of a column, comprises a column, a boom is arranged directly above the column, one side of the upper end of the column is connected to the boom via a connecting piece, a suspended balancing weight is provided at the left end of the boom, the right end of the boom is connected to a hanging boat via a steel wire rope, a hydraulic cylinder is connected to one side of the top of the column, and the upper end of the hydraulic cylinder is connected to the side wall of the boom.

[0008] As a preferred technical solution of the present invention, the boom is of multi-section telescopic type.

[0009] As a preferred technical solution of the present invention, the boom can be driven by the hydraulic cylinder to rotate downward around the connecting piece to form a lying position.

The boom is retracted in multiple sections, so that the force is evenly distributed, which enhances the stability and firmness during operation, avoids the up and down swing of the boom head, and makes the manned platform suspended by steel wire below the boom head more stable and comfortable.

[0015] 2. The maximum extension distance of the boom of the utility model from the center of the supporting column to the outside is 45 meters, which can meet the working requirements of different facades. The telescopic adjustment of the boom expands the activity radius and can flexibly change the horizontal distance between the gondola and the column. The lifting and lowering adjustment of the gondola under the traction of the wire rope expands the vertical range of construction activities. The structure adapts to the different heights of buildings, meets the various structural forms of the facades and the requirements of the size of the cleaning area.

[0016] 3. The arm length of the suspended balance weight at the rear side of the boom support point of the utility model is designed to be ultra-short, and the balance arm at the rear side is only 5.293 meters, which reduces the space occupied by rotation, is more beneficial for areas with limited activity space and achieves a hidden function.

[0017] 4. The extension and lowering adjustment of the column of the utility model can drive the lifting arm, suspended balance weight and hanging boat of the window cleaning machine to rise above the roof curtain wall, so as to facilitate the cleaning and maintenance of the window cleaning machine. The height of the column can be increased from 5.05 meters to 11.16 meters, adapting to the requirements of different heights of roof curtain walls. BRIEF DESCRIPTION OF THE DRAWINGS

Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0025] See also Figure 1-4 A window cleaning machine with a retractable boom and column pitching and lifting functions includes a column 1, an arm 2 is arranged directly above the column 1, the upper end of the column 1 is connected to the arm 2 through a connecting piece 7, the left end of the arm 2 is provided with a suspended balancing weight 3, the right end of the arm 2 is connected to a hanging boat 5 through a wire rope 4, and a hydraulic cylinder 6 is connected to the top side of the column 1, and the upper end of the hydraulic cylinder 6 is connected to the side wall of the arm 2.

[0026] Among them, the boom 2 is a multi-section telescopic type, which makes the force evenly distributed, enhances the stability and firmness during operation, avoids the up and down swing of the boom head, and makes the manned platform suspended by steel wire below the boom head more stable and comfortable.

[0027] Among them, the boom 2 can be rotated downward 45 degrees around the connecting part 7 and lie down under the drive of the hydraulic cylinder 6. When not working, the boom in the retracted state lies down 45 degrees and stops, so that the window cleaning machine can be hidden in the curtain wall of the building without affecting the beauty of the building.

[0028] The connecting member 7 and the boom 2 are movably connected.

[0029] The hydraulic cylinder 6 is movably connected to the boom 2 and the column 1 .

[0030] Among them, column 1 is a hydraulic pitch lifting column, which can drive the window cleaning machine boom 2, suspended balance weight 3, and crane 5 to rise above the roof curtain wall to facilitate the cleaning and maintenance of the window cleaning machine. The height of the column can be increased from 5.05 meters to 11.16 meters, adapting to the requirements of different heights of roof curtain walls.

[0031] The working principle and use process of the utility model are as follows: first, when working, the boom 2 can be extended through the multi-section telescopic boom 2, and the height can be adjusted through the column 1. With the cooperation of the hydraulic machine station, the hydraulic cylinder 6 can lift the boom 2 to make it slightly raised in the horizontal direction. The multi-section telescopic boom 2 makes the force uniform, enhances the stability and firmness during work, avoids the up and down swing of the boom head, and makes the manned platform suspended by the steel wire below the boom head more stable and comfortable;

[0032] The maximum outward extension distance of the boom 2 from the center of the supporting column is 45 meters, which can meet the working requirements of different facades. The telescopic adjustment of the boom 2 expands the activity radius and can flexibly change the horizontal distance between the gondola 5 and the column 1. The lifting and lowering adjustment of the gondola 5 under the traction of the wire rope 4 expands the vertical construction activity range. This structure adapts to different building heights, meets various structural forms of facades and the requirements of the size of the cleaning area;

[0033] The suspended counterweight 3 at the rear of the boom 2 support point has an ultra-short arm length design, with the rear counterweight being only 5.293 meters long. This reduces the space occupied by rotation, making it more advantageous for areas with limited space and achieving a hidden function.

[0034] Column 1 is a hydraulically pitched lifting column. Its pitch, extension, and lowering adjustment drives the window cleaning machine's boom 2, suspended counterweight 3, and gondola 5 to rise above the roof curtain wall, facilitating cleaning and maintenance operations. Column 1 can be raised from 5.05 meters to 11.16 meters to accommodate varying roof curtain wall heights.

[0035] During resetting, the hydraulic cylinder 6 is reset, so that the boom 2 in the retracted state is stopped at a 45-degree angle, so that the window cleaning machine can be hidden in the building curtain wall without affecting the aesthetics of the building. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
