Description

Technical Field

[0001] This utility model relates to the field of building cleaning equipment technology, specifically to a window cleaning machine suspended basket rotating curtain wall platform. Background Technology

[0002] With the rapid development of the modern construction industry, glass curtain walls are widely used in high-rise buildings due to their aesthetic appeal and light transmission. However, because glass curtain walls are exposed to the external environment for a long time, they are prone to dust accumulation and pollution, affecting their appearance. They need to be cleaned every once in a while. In order to improve cleaning efficiency and safety, a window cleaning machine basket is needed.

[0003] Existing window cleaning machine cradles are mostly fixed structures, capable only of lifting and horizontal movement. When encountering concave surfaces of curtain walls, the cradle cannot penetrate the concave area, resulting in cleaning dead zones. Although some improved cradles attempt to adjust the cleaning position by using telescopic arms, the telescopic structure changes the hoisting center of gravity of the entire device when moving the cradle into the concave curtain wall, making it prone to tilting and swaying. Moreover, in high-altitude working environments, they are greatly affected by external factors such as wind, resulting in low cleaning efficiency and high safety hazards. Therefore, we need to propose a rotating curtain wall platform for window cleaning machine cradles. Utility Model Content

[0004] The purpose of this utility model is to provide a rotating curtain wall platform for a window cleaning machine. The first hanging basket is used to clean the exterior curtain wall. When cleaning the concave area of ​​the glass curtain wall, a rotating plate mounted on the bottom via a rotating rod adjusts the angle of the second hanging basket, allowing it to penetrate deeper into the concave area for cleaning. A counterweight mechanism at the other end of the rotating plate maintains the balance of the entire device. Furthermore, the counterweight position can be dynamically adjusted by changing the distance between the counterweight and the second hanging basket, further optimizing the equipment's balance performance and solving the problems mentioned in the background art.

[0020] 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.

[0021] Please see Figures 1-4 This utility model provides a rotating curtain wall platform for a window cleaning machine, including a first hanging basket 1. A rotating rod 2 is rotatably mounted through a bearing at the bottom of the inner cavity of the first hanging basket 1. A rotating plate 3 is fixedly mounted at the bottom of the rotating rod 2. A drive mechanism 4 for transmitting power to the rotating rod 2 is installed inside the first hanging basket 1. A counterweight mechanism 5 is installed at one end of the rotating plate 3. A second hanging basket 6 for cleaning the concave surface of the curtain wall is installed at the other end of the rotating plate 3. Buffer components 7 are installed on the side of the first hanging basket 1, the counterweight mechanism 5, and the second hanging basket 6 that need to be close to the curtain wall. The counterweight mechanism 5 includes a fixed frame 51 fixedly mounted at one end of the rotating plate 3. Two sets of fixed rods 52 are fixedly mounted inside the fixed frame 51. A set of counterweight blocks 53 is movably mounted inside the fixed frame 51. The counterweight blocks 53 are slidably fitted onto the outer arc surface of the two sets of fixed rods 52. An electric push rod 54 is bolted to the inner wall of the fixed frame 51. The output end of the electric push rod 54 is bolted to one side of the counterweight block 53.

[0022] In use, the first suspended basket 1 is used to clean the exterior curtain wall. When cleaning the concave area of ​​the glass curtain wall, the second suspended basket 6 is adjusted by rotating the rotating plate 3 installed at the bottom via the rotating rod 2, allowing the second suspended basket 6 to penetrate into the concave area for cleaning the glass curtain wall inside. The counterweight mechanism 5 at the other end of the rotating plate 3 activates the electric push rod 54 to drive the counterweight block 53 to move back and forth along the fixed rod 52 inside the fixed frame 51, thereby changing the distance between the counterweight block 53 and the second suspended basket 6, keeping the center of gravity of the entire device balanced and achieving dynamic adjustment of the counterweight position. The drive mechanism 4 provides driving force for the rotating rod 2 to drive the rotating plate 3 to rotate. Several sets of buffer components 7 protect the parts of the device that may touch the curtain wall, preventing direct impact and damage to the glass curtain wall. The bottom of the rotating plate 3 and the first suspended basket 1 also need to be protected with an anti-detachment structure (not shown in the figure) to improve safety. The outer sides of the first suspended basket 1 and the second suspended basket 6 are surrounded by protective netting to further improve safety.

[0023] The drive mechanism 4 includes two sets of motors 41 bolted to the bottom of the first suspended basket 1. The two sets of motors 41 are located on both sides of the rotating rod 2, and the output shafts of the two sets of motors 41 are keyed to a set of driving wheels 42. A driven wheel 43 is fixedly mounted on the top of the rotating rod 2. The outer sides of the two sets of driving wheels 42 are respectively meshed with the outer sides of the driven wheels 43. The driving wheels 42 are driven to rotate by the dual motors 41, which in turn drives the driven wheels 43 and the rotating rod 2 to rotate. Compared with the single motor 41 drive, the dual motor 41 drive structure not only improves the transmission efficiency and power output stability, but also allows the other set of motors 41 to temporarily maintain basic operation when one set of motors 41 fails, reducing the risk of equipment downtime. The two sets of motors 41 run synchronously but in opposite directions to ensure that the driven wheel 43 can rotate effectively. It is worth noting that the coupling between the motor 41 and the driving wheel 42 is fixed by a support assembly (not shown in the figure) to prevent the output bearing of the motor 41 from being subjected to forces other than torsional force.

[0024] The bottom of the first suspended platform 1 is equipped with a protective cover 44. The protective cover 44 is fitted on the outside of the motor 41, the drive wheel 42, and the driven wheel 43. The protective cover 44 is made of stainless steel and has good rust and corrosion resistance. It protects the core components of the drive mechanism 4 and can effectively block debris, rainwater, and dust falling during high-altitude operations from corroding the drive mechanism 4, extending the service life of the drive mechanism 4, and avoiding safety hazards caused by exposed transmission components.

[0025] The buffer assembly 7 includes two sets of support rods 71. One end of each set of support rods 71 ​​is fixedly mounted on a support plate 72. Three sets of sliding rods 73 are slidably mounted through the support plate 72. The support rods 71 ​​are made of seamless steel pipes. One end is welded and fixed to the protective position of the first suspended basket 1, the second suspended basket 6, or the counterweight mechanism 5. The other end is fixedly mounted on the support plate 72. The support plate 72 is a rectangular steel plate used to install the sliding rod 73 assembly. Three sets of sliding rods 73 are slidably mounted through the support plate 72. Linear bearings are installed at the connection between the sliding rods 73 and the support plate 72 to reduce the friction when the sliding rods 73 move.

[0026] Each of the three sets of sliding rods 73 has a limiting plate 75 fixedly installed at one end. The limiting plate 75 is used to limit the movement of the sliding rod 73 and prevent the sliding rod 73 from falling off the support plate 72. The three sets of sliding rods 73 have a buffer plate 74 fixedly installed at the outer end of the support plate 72. The buffer plate 74 is made of elastic steel plate and has a certain deformation capacity, which can further enhance the buffering effect.

[0027] Each of the three sets of sliding rods 73 has a spring 76 movably mounted on its outer arc surface between the support plate 72 and the buffer plate 74. The spring 76 is a high-strength compression spring with good elastic restoring performance. When the buffer plate 74 is subjected to an impact force, the spring 76 is compressed, converting the impact force into the elastic potential energy of the spring 76, thereby achieving buffering and shock absorption. When the impact force disappears, the spring 76 returns to its original position, causing the buffer plate 74 to return to its original position. A rubber pad 77 is installed on one side of the buffer plate 74. The rubber pad 77 is made of aging-resistant rubber material with a certain degree of surface roughness, which can further alleviate the impact force and increase the friction between the equipment and the curtain wall surface when the equipment is close to the curtain wall, preventing the equipment from sliding.

[0028] Both ends of the first suspended platform 1 are fixedly equipped with a set of lifting lugs 8. Each set of lifting lugs 8 is connected to the hoisting equipment on the roof via a set of cables. The lifting lugs 8 are made using a forging process and are welded to the top frame of the first suspended platform 1. The welds are inspected for flaws to ensure connection strength. The cables, made of high-strength steel wire rope, feature high tensile strength and wear resistance. This double-lug 8 hoisting structure ensures more even stress distribution on the first suspended platform 1, improving stability during the hoisting process.

[0029] In practical use: Before operation, start the electric actuator 54 through the control system, adjust the position of the counterweight 53 to ensure the rotating plate 3 is in a horizontal and balanced state; test the drive mechanism 4, start the two sets of motors 41, and observe whether the rotating rod 2 rotates smoothly to ensure that the second suspended platform 6 can rotate flexibly to the required angle. Lifting and positioning: Slowly lower the first suspended platform 1 to the starting position using the rooftop lifting equipment, adjust the equipment position so that the rubber pad 77 of the buffer component 7 gently contacts the curtain wall surface to avoid rigid collisions. During routine area cleaning, such as... Figure 1In the shown state, the operator cleans the regular area of ​​the curtain wall inside the first suspended platform 1, using the lifting and horizontal movement of the first suspended platform 1 to achieve large-area cleaning; when encountering a concave surface of the curtain wall, the control system activates the drive mechanism 4, and the two sets of motors 41 drive the drive wheel 42 to rotate, which in turn drives the driven wheel 43 and the rotating rod 2 to rotate. The rotating plate 3 drives the second suspended platform 6 to slowly enter the concave area, while the electric push rod 54 adjusts the position of the counterweight 53 in real time to maintain the balance of the equipment. Figure 2 As shown, another operator performs precise cleaning of the concave area inside the second suspended basket 6; after the cleaning operation is completed, the second suspended basket 6 is rotated back to its original position, the counterweight 53 is adjusted to the initial balance position, and the first suspended basket 1 is slowly lifted to the rooftop by the hoisting equipment to complete the operation.
