[0002] Steel box girders, also known as steel plate box girders, are a common structural form for long-span bridges. They are generally used on bridges with large spans. Their shape resembles a box, hence the name steel box girder. Steel plate box girders are a frequently used structural form in engineering. To study the influence of diaphragm spacing on the distortion of simply supported steel box girders under concentrated loads, this study compares the distortion and rigid torsional effects of simply supported steel box girders with different numbers of diaphragms under concentrated loads, obtaining the curve of the maximum distortion effect as a function of the number of diaphragms. A concentrated load is applied to the top of the box girder web, and calculations are performed using a load decomposition method under four load conditions: distortion, rigid torsion, symmetrical bending, and eccentric load.

[0003] In the existing technology, the installation of components such as retaining formwork, drainage pipes and guardrails on steel box girders are all high-altitude operations. These construction operations not only require high precision, but also must ensure the safety of construction personnel. When using suspended baskets to install steel box girder surfaces, although the problem of high-altitude operations can be solved to some extent, the working range is relatively small and inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the problem that while the existing technology of using suspended platforms for steel box girder surface installation can solve the problem of high-altitude operations to some extent, the operating range is relatively narrow and inconvenient to use. Therefore, this invention proposes a self-propelled engineering suspended platform for high-altitude installation of steel box girders.

[0006] Preferably, the output end of the rotary motor rotates through the inner bottom of the reinforcing cage, and multiple reinforcing blocks are fixedly connected at equal intervals on the outer surface of the connecting frame.

[0007] Preferably, the inner bottom of the walking plate is symmetrically fixed with multiple fixing rods, and the multiple fixing rods are arranged in two groups.

[0008] Preferably, each of the two sets of fixed rods has a handrail fixedly connected to its top, and one end of each handrail is fixedly connected to the outer surface of one side of the walking board.

[0009] Preferably, an auxiliary plate is provided between the tops of the two walking plates, and the length of the auxiliary plate is less than the length of the walking plates.

[0010] Preferably, a fixing post is fixedly connected to the inner bottom of the walking plate, and fixing holes are symmetrically opened on the top of the auxiliary plate, with the fixing holes and fixing posts being matched.

[0011] Preferably, the diameter of the fixing hole is larger than the diameter of the fixing post, and handles are fixedly connected to the outer surfaces of both sides of the auxiliary plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a self-propelled engineering suspended platform for high-altitude installation of steel box girders, comprising: a carrier 1, a hydraulic rod 2 installed on the top of the carrier 1, an installation plate 3 fixedly connected to the telescopic end of the hydraulic rod 2, a trapezoidal frame 4 fixedly connected to the top of the installation plate 3, steel cages 5 symmetrically fixedly connected to the bottom of the trapezoidal frame 4, a rotary motor 6 fixedly connected to the inner bottom of each of the two steel cages 5, a connecting frame 7 fixedly connected to the output end of each of the two rotary motors 6, and a traveling plate 9 fixedly connected to the opposite face of each of the two connecting frames 7. The output end of the rotary motor 6 rotates through the inner bottom of the steel cage 5, and multiple reinforcing blocks 8 are fixedly connected at equal intervals to the outer surface of the connecting frame 7. Multiple fixing rods 10 are symmetrically fixedly connected to the inner bottom of the traveling plate 9, and the multiple fixing rods 10 are arranged in two groups. Each group of fixing rods 10 has a handrail 11 fixedly connected to the top of its top. One end of each handrail 11 is fixedly connected to one side of the outer surface of the traveling plate 9. An auxiliary plate 13 is provided between the tops of the two traveling plates 9, and the length of the auxiliary plate 13 is less than the length of the traveling plate 9.

[0023] The overall effect of Embodiment 1 is as follows: During the high-altitude installation of the steel box girder, the carrier 1 is a self-propelled vehicle body with hydraulic rods 2 installed on its flat bearing surface. When the carrier 1 moves to a suitable working point on the bridge, a force-bearing trapezoidal frame 4 is installed on the mounting plate 3, and steel cages 5 are symmetrically installed from the bottom of the trapezoidal frame 4. Then, the hydraulic rods 2 are activated. When the extension end reaches its extension limit, the height of the steel cages 5 can be raised. Then, the connecting frame 7 and the walking plate 9 are installed in sequence. The two rotary motors 6 are activated simultaneously. The two rotary motors 6 rotate in opposite directions, causing the two walking plates 9 to unfold to both sides. After the hydraulic rods 2 are reset, their extension ends retract, causing the supported overall structure to descend, so that the two walking plates 9 are under the bridge. The two rotary motors 6 are activated again, and their output ends rotate in opposite directions, making it convenient for the two walking plates 9 to rotate to the bottom of the bridge and close together. Then, the workers stand on the walking plates 9, and the auxiliary plate 13 is set up between the two walking plates 9 to form a safe walking construction passage. With the self-propelled nature of the carrier 1, it is convenient for personnel to carry out installation work under the bridge.

[0024] Example 2: As Figures 1-4 As shown, a fixed post 12 is fixedly connected to the inner bottom of the walking plate 9, and a fixed hole 14 is symmetrically opened on the top of the auxiliary plate 13. The fixed hole 14 is matched with the fixed post 12. The diameter of the fixed hole 14 is larger than the diameter of the fixed post 12. Handles 15 are fixedly connected to the outer surfaces of both sides of the auxiliary plate 13.

[0025] The overall effect of embodiment 2 is that when the auxiliary board 13 is erected, the handles 15 on both sides make it easy for people to grab and drag the auxiliary board 13. By symmetrically opening fixing holes 14 on the top of the auxiliary board 13 and setting fixing posts 12 on the top of the two walking boards 9 respectively, it is easy to limit the movement when erecting the two walking boards 9, preventing the auxiliary board 13 from sliding and causing danger to people. It is highly practical.

[0026] Working principle: During the high-altitude installation of the steel box girder, the carrier 1 is a self-propelled vehicle with hydraulic rods 2 installed on its flat bearing surface. When the carrier 1 moves to a suitable working point on the bridge, a load-bearing trapezoidal frame 4 is installed on the mounting plate 3, and steel cages 5 are symmetrically installed from the bottom of the trapezoidal frame 4. Then, the hydraulic rods 2 are activated. At their extension limit, the extension end can lift the steel cages 5 upwards. Next, the connecting frame 7 and the traveling plate 9 are installed sequentially. Simultaneously, two rotary motors 6 are activated, rotating in opposite directions, causing the two traveling plates 9 to unfold to both sides. Then, by resetting the hydraulic rods 2, their extension ends retract, causing the supported overall structure to descend, positioning the two traveling plates 9 below the bridge. The two rotary motors are then activated again. 6. The output ends of the two rotary motors 6 rotate in opposite directions, making it convenient for both walking plates 9 to rotate to the bottom of the bridge and close together. After that, the workers stand on the walking plates 9 and set up the auxiliary plate 13 between the two walking plates 9 to form a safe walking construction passage. With the self-moving of the carrier 1, it is convenient for personnel to carry out installation work under the bridge. When setting up the auxiliary plate 13, handles 15 are set on both sides of it to make it easy for personnel to grab and drag the auxiliary plate 13. Fixing holes 14 are symmetrically opened on the top of the auxiliary plate 13, and fixing posts 12 are set on the top of the two walking plates 9 respectively to limit the movement when setting up the two walking plates 9 and prevent the auxiliary plate 13 from sliding and causing danger to personnel. It is highly practical.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
