Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge wet joint construction technology, specifically a safe operation platform for wet joints of highway bridges. Background Technology
[0002] A wet joint refers to a joint where prestressed concrete beams are prefabricated in sections, cantilevered and assembled into a large-span continuous beam, with the beam sections connected by cast-in-place concrete. The construction quality of wet joints can easily affect the lifespan and stability of the entire bridge. The construction of wet joints requires working at heights, and currently, suspended platforms are mainly used as operating platforms to facilitate worker work. However, to expand the workers' working area, the structure of the suspended platforms is generally large, leading to inconvenience in transportation and storage, and poor practicality. Therefore, those skilled in the art have proposed a safe operating platform for wet joints of highway bridges to solve the problems mentioned above. Utility Model Content

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] Please see Figures 1-6 A safe operating platform for wet joints of highway bridges includes a mounting frame 1; two limit rods 2 are installed inside the mounting frame 1 and are symmetrically arranged inside the mounting frame 1; two movable frames 3 are slidably arranged on the limit rods 2; two lifting rods 6 are installed at the bottom of the movable frames 3 and are symmetrically arranged on the movable frames 3; the platform also includes:
[0022] A drive mechanism is provided inside the mounting frame 1 and connected to the movable frame 3, and is used to drive the movable frame 3 to move.
[0023] The suspended platform mechanism is connected to the end of the boom 6 away from the movable frame 3, and is used to provide a construction platform for workers. The suspended platform mechanism includes two support seats 7 connected to the boom 6. Fixed side plates 13 are installed on the support seats 7, and two symmetrically distributed fixed plates 8 are also installed on the support seats 7. A first folding assembly is movably arranged between the fixed plates 8 of the two support seats 7, and two sets of second folding assemblies are arranged between the ends of the two fixed side plates 13. The first folding assembly and the second folding assembly, together with the fixed side plates 13, can form a platform for workers to carry out construction work, and can also fold the suspended platform mechanism.
[0024] By connecting the external lifting mechanism to the mounting frame 1, the height of the entire suspended platform mechanism can be adjusted by the lifting mechanism. When the first folding component and the second folding component are not folded, the first folding component, the second folding component and the fixed side plate 13 form a platform for workers to carry out construction work. When not in use, the first folding component and the second folding component are folded, so that the space occupied by the entire suspended platform mechanism is reduced, making it convenient for transportation or storage.
[0025] In one embodiment, the drive mechanism includes a bidirectional threaded rod 4 rotatably disposed in the middle of the mounting frame 1, two movable frames 3 are threadedly connected to the bidirectional threaded rod 4 and are symmetrically arranged on the bidirectional threaded rod 4, and a motor 5 connected to the bidirectional threaded rod 4 is mounted on the outer wall of the mounting frame 1.
[0026] When in use, the suspended platform mechanism is opened by starting the motor 5 via an external controller. The motor 5 drives the bidirectional threaded rod 4 to rotate, causing the two moving frames 3 to move away from each other, thus opening the entire suspended platform mechanism. When the suspended platform mechanism is not in use, the motor 5 reverses, causing the bidirectional threaded rod 4 to reverse, and the two moving frames 3 to move closer to each other. During this process, the suspension rod 6 drives the two support seats 7 to move closer to each other, causing the first folding component and the second folding component to fold, thereby reducing the space occupied by the suspended platform mechanism.
[0027] In one embodiment, the first folding assembly includes a first intermediate frame 12 and two movable base plates 9. The two ends of the movable base plates 9 are rotatably provided with a first rotating shaft 10 and a second rotating shaft 11. The second rotating shaft 11 is rotatably connected to the first intermediate frame 12, and the first rotating shaft 10 is rotatably connected to the fixed plate 8.
[0028] When the first folding assembly is unfolded, that is, when the distance between the two support seats 7 reaches its maximum, the two movable base plates 9 on both sides of the first intermediate frame 12 are straightened. When the first folding assembly is folded, the two support seats 7 will move closer together, and the first intermediate frame 12 will move upward, so that the two movable base plates 9 are folded and fitted together.
[0029] In one embodiment, the second folding assembly includes a second intermediate frame 17 and two movable side plates 14. The two ends of the movable side plates 14 are rotatably provided with a third rotating shaft 15 and a fourth rotating shaft 16. The fourth rotating shaft 16 is rotatably connected to the second intermediate frame 17, and the third rotating shaft 15 is rotatably connected to the support base 7 and the top of the fixed side plate 13.
[0030] When the second folding assembly is unfolded, the distance between the two support seats 7 reaches its maximum. At this time, the two movable side plates 14 on both sides of the second intermediate frame 17 will be straightened. When the second folding assembly is folded, the two support seats 7 will move closer together. At this time, the second intermediate frame 17 will move away from the first intermediate frame 12, so that the two movable side plates 14 are folded and fitted together.
[0031] In one embodiment, a support block 18 is installed at the bottom of the second intermediate frame 17, and the support block 18 is provided with bolts 19 that are connected to the first intermediate frame 12.
[0032] When the first folding assembly and the second folding assembly are folded, the support block 18 at the bottom of the second intermediate frame 17 of the second folding assembly extends into the lower ends of the first intermediate frame 12. The support block 18 can support the two ends of the first intermediate frame 12. With the help of the bolts 19, the first intermediate frame 12 and the second intermediate frame 17 can be firmly connected, thereby making the overall stability of the unfolded basket mechanism better.
[0033] This utility model connects an external lifting mechanism to the mounting frame 1, and adjusts the height of the entire suspended platform mechanism through the lifting mechanism. When the first folding component and the second folding component are not folded, the first folding component, the second folding component, and the fixed side plate 13 form a platform for workers to carry out construction work. When not in use, the first folding component and the second folding component are folded, which reduces the space occupied by the entire suspended platform mechanism and facilitates transportation or storage.
