Abstract
Description
A foldable bridge deck high-altitude work basket Technical Field
[0001] This utility model relates to the technical field of bridge construction equipment, specifically to a foldable bridge deck high-altitude operation basket. Background Technology
[0002] In bridge construction, after the beams are installed, the construction of diaphragms and end (middle) beams between adjacent beams is required. During this process, workers must descend through the wet joints to the area beneath the beams to work on the reinforcement and formwork of the diaphragms and end (middle) beams. Due to the confined working space and the lack of a platform or support beneath the beams, a common practice is for workers to weld steel bars into a steel cage for operation. The upper steel bars of the cage are bent into U-shaped hooks, which are then used to hang the cage on the embedded steel bars at the wet joints. Workers, secured by safety harnesses, enter the cage to begin their work.
[0003] However, since the steel cage is made of welded steel bars, it is heavy and bulky, which is not only difficult to transport and store, but also limited to a height of only 40-50cm due to weight restrictions. This is about knee height for construction workers, leaving most of their bodies in a free-floating state, which makes them extremely prone to falling from heights. Summary of the Invention

Detailed Implementation
[0030] To better understand the purpose, structure, and function of this utility model, the following detailed description of a foldable bridge deck high-altitude operation basket provided by this utility model is provided in conjunction with the accompanying drawings, so that those skilled in the art can better understand and implement this utility model. However, the embodiments described are not intended to limit this utility model.
[0031] Please refer to Figures 1 to 7. This embodiment of the application provides a foldable bridge deck aerial work platform, including a first ladder 10, a second ladder 20, a base frame 30, and a base plate 40. The first ladder 10 and the second ladder 20 are arranged parallel to each other, and their lower ends are rotatably connected to both ends of the base frame 30. Multiple rotating rods 11, evenly spaced and longitudinally distributed, are rotatably connected to both sides of the first ladder 10. The end of each rotating rod 11 away from the first ladder 10 is rotatably connected to one side of the second ladder 20. A first rotating shaft 12 is located above the base frame 30 at the lower end of the first ladder 10. The base plate 40 is located between the first ladder 10 and the second ladder 20, and one end of the base plate 40 is rotatably connected to the first rotating shaft 12. Both the first ladder 10 and the second ladder 20 are made of high-strength steel pipes, which are lighter than traditional steel cages and easier to transport. Both the first and second ladders 10 and 20 are equipped with two longitudinal bars and multiple horizontal bars that are equally spaced and longitudinally connected between the two longitudinal bars; the longitudinal bars and horizontal bars are welded together to improve the overall strength and stability of the foldable bridge deck high-altitude operation basket.
[0032] Because it is equipped with a first hoisting ladder 10, a second hoisting ladder 20, a base frame 30 and a pad 40, and the first hoisting ladder 10 is equipped with multiple rotating rods 11 and a first rotating shaft 12, the cooperation between the above components can not only provide a stable and safe working environment for construction workers, but also realize the overall folding function of the hoisting basket, which is convenient for transportation and storage and reduces the space occupied.
[0033] Specifically, by setting up the first ladder 10 and the second ladder 20, they are not only used to hang on the top surface of two adjacent beams 1 to facilitate the entry and exit of construction personnel into the foldable bridge deck aerial work platform, but also used together with multiple rotating rods 11 to form a fully protected working space, allowing the entire body of the construction personnel to enter the foldable bridge deck aerial work platform, greatly improving construction safety and effectively protecting the personal safety of the construction personnel. By rotatably connecting the two ends of the rotating rods 11 to the first ladder 10 and the second ladder 20 respectively, the first ladder 10 can move upward or downward relative to the second ladder 20, and during the upward or downward movement of the first ladder 10 relative to the second ladder 20, it can move closer to or away from the second ladder 20, thereby realizing the folding or opening of the foldable bridge deck aerial work platform. The rotatable connection can be achieved by setting the same number of second rotating shafts as the rotating rod 11 on both sides of the longitudinal rods of the first ladder 10 and the second ladder 20, and by opening shaft holes at both ends of the rotating rod 11 that are adapted to the second rotating shafts, allowing the second rotating shafts to rotatably engage with the shaft holes of the rotating rod 11. A base frame 30 is provided to provide a support platform for the pad 40 and construction personnel. Furthermore, a third rotating shaft is provided at the lower end of the first ladder 10 and the second ladder 20; shaft holes adapted to the third rotating shafts are provided at both ends of the base frame 30, allowing for rotatable engagement with the third rotating shafts of the first and second ladders. Simultaneously, the pad 40 not only provides a more comfortable standing surface for construction personnel but also prevents tools from falling through the gaps in the base frame 30. The first pivot 12 of the first ladder 10 is located above the third pivot. The pivot 12 rotates with the shaft hole at one end of the pad 40, allowing the pad 40 to rotate around the first pivot 12. This allows the pad 40 to be easily opened when the foldable bridge deck aerial work platform is opened, i.e., the pad 40 can be rotated towards the side closer to the upper surface of the base frame 30 and attached to the upper surface of the base frame 30; or the pad 40 can be easily folded when the foldable bridge deck aerial work platform needs to be folded, i.e., the pad 40 can be rotated away from the upper surface of the base frame 30.
[0034] In a preferred embodiment, a longitudinal sleeve 13 is provided on the side of the two longitudinal rods of the first ladder 10 near the second ladder 20; the lower end of the longitudinal sleeve 13 is at a height greater than the base frame 30 than the length of the pad 40; a connecting ear 41 is provided on both sides of the end of the pad 40 away from the first pivot 12; a rope 14 is threaded through the longitudinal sleeve 13, the upper end of the rope 14 is located above the upper end of the longitudinal sleeve 13, and the lower end of the rope 14 passes through the longitudinal sleeve 13 and is connected to the connecting ear 41.
[0035] Because the first ladder 10 is equipped with a longitudinal sleeve 13, and a rope 14 is threaded through the longitudinal sleeve 13, and the pad 40 is equipped with a connecting lug 41, the pad 40 can be easily opened or closed through the cooperation of the above components. When the foldable bridge deck aerial work platform is opened, the pad 40 is rotated towards the upper surface of the base frame 30 under its own weight by lowering the rope 14 until the pad 40 is in contact with the upper surface of the base frame 30. When the foldable bridge deck aerial work platform needs to be folded, the rope 14 is pulled upward to rotate the pad 40 away from the upper surface of the base frame 30 until the pad 40 abuts against the crossbar of the first ladder 10, and then folding is performed. In addition, after the foldable bridge deck aerial work platform is folded, the rope 14 can also be used to bind the first ladder 10 and the second ladder 20 to improve the stability of the folding, so as to facilitate transportation or storage.
[0036] In a preferred embodiment, a pull ring 15 is connected to the upper end of the rope 14, and the diameter of the pull ring 15 is larger than the diameter of the longitudinal sleeve 13. Because the rope 14 is provided with a pull ring 15, and the diameter of the pull ring 15 is larger than the diameter of the longitudinal sleeve 13, it not only makes it convenient for construction personnel to pull the rope 14, but also effectively prevents the rope 14 from slipping into the longitudinal sleeve 13.
[0037] In a preferred embodiment, a transverse sleeve 50 is fixedly connected to the upper end of both the first ladder 10 and the second ladder 20, and a support rod 60 is inserted through each transverse sleeve 50. By setting a transverse sleeve 50 at the upper end of the first ladder 10 and the second ladder 20 respectively, it is not only used to cooperate with the support rod 60 to hang the first ladder 10 and the second ladder 20 between the two beams 1, but also used to insert support rods 60 of different lengths to adapt to wet joints of different widths, thereby improving the applicability of the foldable bridge deck high-altitude operation basket.
[0038] In a preferred embodiment, each support rod 60 has a sliding plate 70 sleeved at both ends, and the bottoms of the two sliding plates 70 on the same side are slidably connected to a slide rail 80. Due to the presence of the sliding plates 70 and the slide rail 80, the sliding plates 70 can move along the length of the slide rail 80 through their cooperation. This facilitates the movement of the foldable bridge deck aerial work platform along the length of the wet joint, reducing the number of times the foldable bridge deck aerial work platform needs to be opened or folded in the same construction section, thus improving construction efficiency.
[0039] In a preferred embodiment, the slide plate 70 includes a base 71, a mounting part 72, a convex connecting block 73, two transverse pulleys 74, and two sets of longitudinal pulleys 75; the mounting part 72 is fixed to the upper end of the base 71; the upper end of the convex connecting block 73 is connected to the lower end of the base 71, and the lower end of the convex connecting block 73 extends downward into the interior of the slide rail 80; the two transverse pulleys 74 are rotatably connected to both sides of the lower end of the convex connecting block 73; the two sets of longitudinal pulleys 75 are located between the two transverse pulleys 74 and are rotatably connected to the convex connecting block 73.
[0040] Because the slide plate 70 is equipped with a base 71, a mounting part 72, a convex connecting block 73, a transverse pulley 74, and a longitudinal pulley 75, the cooperation between these components reduces swaying on the slide rail 80, enabling stable and flexible sliding, thereby improving the stability of the foldable bridge deck aerial work platform during movement. Specifically, the mounting part 72 allows the support rod 60 to be inserted into its slot, providing support while simultaneously moving the support rod 60 along the length of the slide rail 80. Furthermore, the transverse pulley 74 abuts against the side wall of the slide rail 80, improving not only the flexibility of the slide plate 70's movement but also preventing it from swaying left and right relative to the slide rail 80, thus enhancing the stability between the slide plate 70 and the slide rail 80.
[0041] In a preferred embodiment, a plurality of locking elements 72A for fastening the support rod 60 are provided on the outer side wall of the mounting part 72. Since the locking elements 72A (such as bolts, screws, etc.) are provided on the outer side wall of the mounting part 72, the connection stability between the mounting part 72 and the support rod 60 can be improved by tightening the locking elements 72A, thereby further improving the overall stability and safety of the foldable bridge deck aerial work platform.
[0042] In a preferred embodiment, anti-slip pads 90 are provided at the upper ends of the crossbars of both the first ladder 10 and the second ladder 20. Because the anti-slip pads 90 are provided on the crossbars of the first ladder 10 and the second ladder 20, slippage when construction workers step on the crossbars can be prevented, facilitating access for construction workers to the foldable bridge deck high-altitude work basket and effectively ensuring the personal safety of construction workers.
[0043] In this embodiment, a foldable bridge deck aerial work platform is used by first fixing two slide rails 80 along the length of the wet joint to the beam slab 1 on both sides of the wet joint. Then, two support rods 60 are inserted into the transverse sleeves 50 on the first ladder 10 and the second ladder 20, and the foldable bridge deck aerial work platform is lowered into the gap of the wet joint until the two ends of the support rods 60 on the second ladder 20 abut against the beam slab 1 on both sides of the wet joint. Then, the transverse sleeves 50 on the first ladder 10 are pushed down, causing the first ladder 10 to move downward relative to the second ladder 20, thereby opening the first ladder 10 away from the second ladder 20 until the two ends of the support rods 60 on the first ladder 10 abut against the beam slab 1 on both sides of the wet joint. At this time, the foldable bridge deck aerial work platform is fully opened. Next, a sliding plate 70 is attached to each end of the two support rods 60, and the sliding plate 70 is assembled onto the corresponding slide rail 80. Simultaneously, the locking piece 72A on the mounting part 72 is tightened to secure the support rods 60. Finally, the rope 14 is lowered until the ground of the pad 40 is in contact with the upper surface of the base frame 30. Construction workers can then enter the foldable bridge deck aerial work platform via the first ladder 10 or the second ladder 20 to perform their work. After construction is completed, the foldable bridge deck aerial work platform is folded in reverse order for transport to the next construction site or for storage.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
