Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, specifically relating to a construction operation platform for the suspension system of a small-span suspension bridge. Background Technology

[0002] A construction platform for suspenders in short-span suspension bridges is an auxiliary device specifically designed for the construction of suspenders in such bridges. The installation and adjustment of suspenders is a crucial step in the construction of short-span suspension bridges. Traditional construction platforms are typically fixed to the bridge structure, requiring workers to climb or use other methods to reach the work area, which is not only inefficient but also poses significant safety risks. To improve construction efficiency and safety, a flexible and height-adjustable construction platform has been developed. This platform is fixed to the main cable via a suspension system, allowing workers to install and adjust suspenders from the platform, greatly improving the convenience and efficiency of the construction process.

[0003] However, existing construction platforms for short-span suspension bridge suspender systems have several shortcomings. First, the platform's movement is relatively limited, typically requiring external equipment for position adjustments, which is complex and time-consuming. Second, the platform's height adjustment is inflexible, necessitating frequent adjustments by workers when working on suspenders at different heights, increasing construction difficulty and time costs. Furthermore, access to and from the platform is inconvenient, requiring workers to climb or use other methods, which not only increases physical exertion but also poses safety hazards. Therefore, improvements to existing construction platforms are needed to enhance construction efficiency and safety. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model achieves stable suspension and flexible movement of the construction platform during high-altitude operations by setting up a suspension structure for the construction platform. Specifically, the construction platform is connected to a hand-operated hoist via a fixed ring, and the hand-operated hoist is then connected to a sling connection structure via a sling. Ultimately, the load-bearing cable bears the main suspension and load-bearing tasks. This structure not only ensures the stable suspension of the construction platform at different heights, but also allows for flexible height adjustment through the hand-operated hoist, greatly improving the convenience and safety of construction.

[0025] Specifically, the traction rope connection structure 9 includes a second fixing ring 91. The second fixing ring 91 is located at the center of the side of the crossbeam 1. A connecting plate 92 is located on one side of the second fixing ring 91. The connecting plate 92 is fixedly connected to the crossbeam 1 by bolts 94. One end of the traction rope 11 is provided with a connecting ring 93 that is connected to the second fixing ring 91.

[0026] By adopting the above technical solution, the traction rope 11 is fixedly connected to the crossbeam 1 through the fixed ring 2 91 and the connecting plate 92, which ensures the stability and reliability of the traction rope 11 when moving the construction platform 10. This connection method can not only withstand a large tensile force, but also ensure that the traction rope 11 will not loosen or fall off during the movement, thereby improving the moving efficiency and safety of the construction platform 10.

[0027] Specifically, the sling connection structure 3 includes a fixing plate 31. The fixing plate 31 is fixed to the side of the longitudinal beam 2. The fixing plate 31 and the longitudinal beam 2 are fixedly connected by fixing bolts 32. A guide wheel 33 is rotatably connected to the center position of the side of the fixing plate 31, and a load-bearing wheel 34 is rotatably connected to the center position of the lower end of the fixing plate 31.

[0028] By adopting the above technical solution, the load-bearing cable 4 moves smoothly within the sling connection structure 3 through the guide wheel 33 and the load-bearing wheel 34, ensuring the stability and flexibility of the sling 6 at different heights and positions. This design can not only effectively distribute the force on the sling 6, but also reduce the wear of the sling 6 during movement and extend its service life.

[0034] By adopting the above technical solutions, the design of the first stop 81 and the second stop 83 can effectively prevent the door panel 13 from rotating excessively when closing, ensuring that the door panel 13 can be accurately aligned with the side of the construction platform 10, thereby improving the closing accuracy of the door panel 13 and the overall stability of the construction platform 10.

[0035] Specifically, a spirit level 12 is installed at the center of the upper end of the construction platform 10.

[0036] By adopting the above technical solution, the level 12 can monitor the level status of the construction platform 10 in real time, ensuring that the construction platform 10 remains level at different heights and positions, thereby improving the accuracy and quality of construction. Construction personnel can adjust the position of the construction platform 10 in a timely manner according to the indication of the level 12, ensuring the smooth progress of the construction process.

[0037] In this embodiment, construction workers can monitor the level of the construction platform 10 in real time using the level 12, and adjust the height using the hand-operated hoist 7 as needed. The design of the rotating plate 84 and the fixing component 8 ensures the stability and safety of the door panel 13, reducing safety hazards for construction workers entering and exiting the construction platform 10. Through these improvements, this utility model not only improves construction efficiency, but also significantly enhances the safety and reliability of the construction process.

Through the traction rope 11 and the traction rope connection structure 9, the construction personnel can flexibly move the construction platform 10 to the required position. Using the hand-operated hoist 7, the construction personnel can finely adjust the height of the construction platform 10 to ensure that the construction platform 10 can accurately reach the construction position of the hoist. The design of the door panel 13 facilitates the entry and exit of the construction platform 10, improves construction efficiency, and reduces the danger of climbing. The level 12 can monitor the level status of the construction platform 10 in real time, ensuring that the construction platform 10 always remains level at different heights and positions, thereby improving the accuracy and quality of construction. Through these improvements, this utility model not only improves construction efficiency but also significantly enhances the safety and reliability of the construction process.
