Description

Technical Field

[0001] This invention relates to the field of construction technology, specifically to a suspended platform for an aerial work platform. Background Technology

[0002] Currently, aerial work platforms are generally required for high-altitude construction work. These platforms use suspended baskets to lift workers to higher positions for building repairs or other construction projects. Currently, when working on bridge walls, the aerial work platform is typically positioned on the bridge deck, its cantilever extended, and the basket lowered from one side of the bridge to the level of the area to be repaired. Workers then stand inside the basket to work on the bridge wall. However, existing suspended baskets have the following drawbacks when used for bridge construction:

[0003] 1. During the construction process, there will still be a constant stream of vehicles passing over the bridge, which will inevitably cause the bridge to vibrate at a certain frequency. This will cause some dust or other impurities to fall down from both sides of the bridge wall. At this time, if the workers are standing in the basket and facing the bridge wall to carry out construction, the falling dust will inevitably interfere with the workers' normal construction. In severe cases, it may even affect the workers' own safety.

[0004] 2. After the workers have completed the repair of one part of the car wall, they need to continue to repair other parts. At this time, the aerial work platform needs to rotate the boom to control the movement of the suspended platform. However, during the movement of the suspended platform, due to the lack of necessary support structure, it will inevitably sway, which can easily affect the workers and thus affect their safety.

[0005] To address these shortcomings, we propose a suspended platform for aerial work platforms. Summary of the Invention

[0006] The purpose of this invention is to provide a suspended platform for an aerial work platform to solve the problems mentioned in the background art.

The drive motor is fixedly mounted on the top surface of the base, and the output shaft of the drive motor is coaxially connected to the drive gear. The drive gear meshes with the gear ring.

[0012] Optionally, the inflation mechanism includes a blower and an inflation pipe. The blower is fixedly mounted on the bottom surface of the rotating ring. One end of the inflation pipe is connected to the air outlet of the blower, and the other end of the inflation pipe is connected to the inflation chamber.

[0013] Optionally, the protective plate has a U-shaped structure, and the two corners of the outer side wall of the protective plate are provided with rounded chamfers, and the two corners of the protective plate extend to the outside of the rotating ring. A cleaning brush is also provided at the two corners of the outer side wall of the protective plate.

[0014] Optionally, the interior of the suspended platform body is also provided with a sliding mechanism, which includes two parallel slide rails symmetrically distributed around the center of the base and a mounting plate. Both slide rails are fixedly connected to the base, and the two ends of the mounting plate are slidably engaged with the two slide rails respectively. The bottom end of the climbing ladder is fixedly connected to the mounting plate.

[0015] Optionally, the top surface of the slide rail is provided with a toothed groove, and both sides of the top surface of the mounting plate are provided with movable slots.

[0020] 4. The protective plate and the rotating ring in this invention are hinged together, so the protective plate can tilt inward to adapt to bridge walls with different degrees of inclination, thus further improving the universality of this invention. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example: Please refer to Figures 1-8 A suspended platform for an aerial work platform includes a platform body 100. The platform body 100 includes a circular base 101 and a rotating ring 102 movably sleeved around the base 101. The rotating ring 102 is a hollow structure with an inflation chamber 103 inside. Protective plates 104 are evenly spaced on its top surface. The bottom of the protective plates 104 is hinged to the top surface of the rotating ring 102. An airflow channel 105 is also provided inside the protective plates 104, and the airflow channel 105 is connected to the inflation chamber 103 via a flexible hose 106. Figure 6 As shown, the bottom surface of the protective plate 104 is provided with a first air nozzle communicating with the airflow channel 105, and the top surface of the rotating ring 102 is provided with a second air nozzle communicating with the inflation chamber 103. The two ends of the hose 106 are respectively connected to the first air nozzle and the second air nozzle. The outer surface of the protective plate 104 is provided with an airflow nozzle 107 communicating with the airflow channel 105, and a flexible barrier part 108 is connected between adjacent protective plates 104. The airflow nozzles 107 are all inclined upwards. In addition, the barrier part 108 can be made of nylon mesh or other flexible materials. The protective plates 104 and the barrier part 108 together form the guardrail structure of the hanging basket to ensure the safety of the staff.

[0032] It is worth mentioning that, in this embodiment, a blocking block 110 is also provided on the top surface of the rotating ring 102, such as... Figure 8 As shown, when the protective plate 104 is kept vertical, the outer surface of the protective plate 104 abuts against the blocking block 110 to prevent the protective plate 104 from tilting outward, thereby causing safety hazards to the construction. In addition, the protective plate 104 is hinged to the rotating ring 102 through a hinge seat, and a torsion spring (not shown in the figure) is installed on the hinge part. Its function is to apply an outward pushing force to the protective plate 104 so that the protective plate 104 always remains vertical when it is not subjected to external forces of the system.

[0033] In this embodiment, the suspended basket body 100 is also provided with a drive mechanism 400 for driving the rotating ring 102 to rotate and an inflation mechanism 500 for inflating the inflation chamber 103. The drive mechanism 400 includes a drive motor 401, a drive gear 402, and a gear ring 403 fixedly connected to the top surface of the rotating ring 102 and distributed circumferentially along the rotating ring 102. The drive motor 401 is fixedly mounted on the top surface of the base 101. The output shaft of the drive motor 401 is coaxially connected to the drive gear 402. The drive gear 402 meshes with the gear ring 403. Therefore, the rotating ring 102 can be directly driven to rotate by the drive motor 401. The rotation causes the protective plate 104 to rotate. The inflation mechanism 500 includes a blower 501 and an inflation pipe 502. The blower 501 is fixedly installed on the bottom surface of the rotating ring 102. One end of the inflation pipe 502 is connected to the air outlet of the blower 501, and the other end of the inflation pipe 502 is connected to the inflation chamber 103. Specifically, the bottom surface of the rotating ring 102 is provided with an air inlet pipe that communicates with the inflation chamber 103. The inflation pipe 502 is connected to the air inlet pipe and is used to directly inflate the inflation chamber 103. After the gas enters the inflation chamber 103, it enters the airflow channel 105 through the hose 106 and is finally sprayed out from the airflow nozzle 107.

[0034] In addition, the protective plate 104 has a U-shaped structure, and both corners of the outer side wall of the protective plate 104 are provided with rounded chamfers, and both corners of the protective plate 104 extend to the outside of the rotating ring 102, such as Figure 3 As shown, cleaning brushes 109 are also provided at the two corners of the outer side wall of the protective plate 104. The cleaning brushes 109 are distributed vertically. When the rotating ring 102 rotates around the base 101, the cleaning brushes 109 can also be used to clean the impurities on the bridge wall, further enriching the function of this embodiment.

[0035] This embodiment also includes a traveling mechanism 200 for clamping the edge of the car wall and traveling along the length of the bridge. The traveling mechanism 200 includes a U-shaped clamping part 201. A first rolling shaft 202 is provided on the inner bottom surface of the clamping part 201, and a second rolling shaft 203 is provided on the inner side wall of the clamping part 201. A liftable clamping block 205 is connected to the inner top surface of the clamping part 201 through a scissor assembly 204. A third rolling shaft 206 is provided on the lower surface of the clamping block 205. A drive cylinder 207 for driving the extension and retraction of the scissor assembly 204 is also provided on the inner top surface of the clamping part 201. Therefore, the movement of the clamping block 205 can be controlled by the drive cylinder 207 and the scissor assembly 204, so that the first rolling shaft 202, the second rolling shaft 203 and the third rolling shaft 206 all roll and adhere to the bridge wall. That is, the traveling mechanism 200 can not only clamp the bridge wall, but also move along the length of the bridge.

[0036] This embodiment also includes a climbing ladder 300, the bottom of which is connected to the suspended platform body 100, and the top of which is connected to the traveling mechanism 200. Specifically, the top of the climbing ladder 300 is provided with a hanging ring 301 that matches the sling on the aerial work platform. Positioning rods 302 are evenly arranged vertically on the side of the climbing ladder 300 facing the traveling mechanism 200. The back of the clamping part 201 is provided with a rod sleeve 208 that matches the positioning rod 302. The rod sleeve 208 is a hollow square tube shape. That is, the aerial work platform moves the climbing ladder 300 and the suspended platform body 100 by connecting the hanging ring 301 with the sling. In addition, since there are many positioning rods 302, the height of the suspended platform body 100 from the top surface of the bridge can be adjusted by connecting different positioning rods 302 and rod sleeves 208.

[0037] Based on the above embodiments, the interior of the suspended platform body 100 is further provided with a sliding mechanism 600. The sliding mechanism 600 includes two parallel slide rails 601 symmetrically distributed about the center of the base 101 and a mounting plate 602. Both slide rails 601 are fixedly connected to the base 101, and both ends of the mounting plate 602 are slidably engaged with the two slide rails 601 respectively. The bottom end of the climbing ladder 300 is fixedly connected to the mounting plate 602. The top surface of the slide rails 601 is provided with toothed grooves 60. 3. Movable slots 604 are provided on both sides of the top surface of the mounting plate 602. Driven gears 605 are provided on the top surface of the mounting plate 602 at each of the movable slots 604. The two driven gears 605 mesh with the toothed grooves 603 on the two slide rails 601, and are coaxially connected via a transmission shaft 606. A servo motor 607 is also provided on the top surface of the mounting plate 602, and the output shaft of the servo motor 607 is coaxially connected to the transmission shaft 606. Figure 5 As shown, the drive shaft 606 is rotatably mounted above the mounting plate 602. Both ends of the drive shaft 606 are coaxially connected to two driven gears 605. Therefore, the driven gears 605 can be directly driven to rotate by the servo motor 607, thereby controlling the relative position between the base 101 and the mounting plate 602. In the specific implementation process, the servo motor 607 can control the sliding of the basket body 100, thereby adjusting the distance between the basket body 100 and the bridge wall.

[0038] It is worth mentioning that since the sliding friction between the slide rail 601 and the mounting plate 602 is relatively large, it is inconvenient to adjust the position of the suspended basket body 100. Therefore, in another embodiment, both ends of the mounting plate 602 are provided with rollers, and the rollers roll and fit against the slide rail 601, thereby helping to reduce the resistance when the suspended basket body 100 moves.

[0039] In summary, in the specific implementation process of this embodiment, the traveling mechanism 200 is first clamped at the edge of the bridge wall, and then the suspended basket body 100 is lifted by the aerial work vehicle and moved to the traveling mechanism 200. The positioning rod 302 is inserted into the rod sleeve 208 to fix the position of the suspended basket body 100. Then, the workers can climb into the suspended basket body 100 through the climbing ladder 300 to carry out repairs and other work on the bridge wall. During the construction process, the driving mechanism 400 can be used to control the rotation of the rotating ring 102, thereby driving the protective plate 104 to rotate. The inflation mechanism 500 is used to inflate the inflation chamber 103, thereby causing the airflow nozzle 107 to spray air towards the bridge wall, so that the bridge wall position where the workers are working can always be kept clean, preventing dust or other impurities from falling into the position and affecting the workers' construction. In addition, as bridges age, dust and dirt inevitably accumulate on the side walls. This accumulation can hinder construction work. Therefore, before construction, workers can use the sliding mechanism 600 to move the suspended platform body 100, allowing the cleaning brush 109 on the suspended platform body 100 to fit against the bridge wall. Then, the drive mechanism 400 controls the rotating ring 102 to rotate, enabling the cleaning brush 109 to clean the bridge wall, thus further facilitating construction.
