[0040] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0042] When a bridge is being cast, the construction platform is used for construction of the cast section, and the maintenance platform is used for inspection and maintenance of the cast section. The construction platform and the maintenance platform are support platforms for operators to walk, stand, or perform other activities.

[0043] In related technologies, the support frame of the construction platform and maintenance platform is fixedly connected to the support device at one end and suspended at the other end, which causes the construction platform and maintenance platform to be unstable and poses a safety hazard.

[0044] Based on this, this application provides a bridge construction and maintenance device based on a suspended grouting bridge building machine, which is applicable to the already poured sections and the cast-in-place sections of a bridge, and the already poured sections and the cast-in-place sections are connected along the length of the bridge.

[0045] The mobile terminal shooting cabinet will be described in detail below through specific embodiments:

[0046] Reference Figures 1 to 3 As shown, this embodiment provides a bridge construction and maintenance device based on a cantilever bridge building machine, including a maintenance platform 2, a construction platform 3, and a connecting platform 4 connecting the maintenance platform 2 and the construction platform 3.

[0047] Maintenance platforms 2 are provided on opposite sides of the poured section along the width of bridge 1, and construction platforms 3 are provided on opposite sides of the poured section along the width of bridge 1. Multiple inverted U-shaped gantry frames are provided on the beam surface of bridge 1. Multiple inverted U-shaped gantry frames are distributed at intervals along the length of bridge 1. Maintenance platforms 2, connecting platforms 4 and construction platforms 3 are all connected to multiple inverted U-shaped gantry frames.

[0048] The inverted U-shaped gantry is connected to the beam surface of bridge 1 via the main beam. Maintenance platforms 2 are connected to both ends of the inverted U-shaped gantry along the width direction of bridge 1, and both ends of maintenance platforms 2 along the length direction of bridge 1 are connected to the inverted U-shaped gantry. This ensures that maintenance platforms 2 are securely connected to the inverted U-shaped gantry, and the inverted U-shaped gantry is more stable on bridge 1 because it is subjected to forces from both sides of the maintenance platforms 2. Similarly, construction platforms 3 are connected to both ends of the inverted U-shaped gantry along the length direction of bridge 1, and both ends of the inverted U-shaped gantry are connected to construction platforms 3 along the width direction of bridge 1. This ensures that construction platforms 3 are securely connected to the inverted U-shaped gantry, and the inverted U-shaped gantry is more stable on bridge 1 because it is subjected to forces from both sides of the construction platforms 3. Workers on maintenance platforms 2 and construction platforms 3 enjoy enhanced safety during maintenance and construction operations.

[0049] like Figure 1 and Figure 2 As shown, taking a cantilever bridge construction machine with three inverted U-shaped gantries as an example, in some embodiments, the bridge 1 includes a pre-cast section and a cast-in-place section connected together. The three inverted U-shaped gantries, along the length of the bridge 1 from the pre-cast section to the cast-in-place section, are respectively the first inverted U-shaped gantry 51, the second inverted U-shaped gantry 52, and the third inverted U-shaped gantry 53. The two ends of the maintenance platform 2 are respectively connected to the first inverted U-shaped gantry 51 and the second inverted U-shaped gantry 52, and the two ends of the maintenance platform 2 are respectively connected to the second inverted U-shaped gantry 52 and the third inverted U-shaped gantry 53. The connecting platform 4 is connected to the second inverted U-shaped gantry 52.

[0050] Because there are side formwork between construction platform 3 and the pouring section, construction platform 3 is farther from bridge 1 than maintenance platform 2. This means construction platform 3 and maintenance platform 2 cannot be directly connected end-to-end. Connecting platform 4 extends along the width of bridge 1, and its two ends along the width of bridge 1 are connected to maintenance platform 2 and construction platform 3 respectively. Workers can switch positions between maintenance platform 2 and construction platform 3 using connecting platform 4. One side of connecting platform 4 along the length of bridge 1 is connected to the second inverted U-shaped gantry 52 to increase the connection area between connecting platform 4 and the second inverted U-shaped gantry 52, which provides support for connecting platform 4.

[0051] In some embodiments, the maintenance platform 2 includes a first maintenance frame 21 and a second maintenance frame 22 distributed along the height direction of the bridge 1. Both the first maintenance frame 21 and the second maintenance frame 22 extend along the length direction of the bridge 1. The two ends of the first maintenance frame 21 along the length direction of the bridge 1 are respectively connected to a first inverted U-shaped gantry 51 and a second inverted U-shaped gantry 52. ​​A lifting assembly 23 is provided between the second maintenance frame 22 and the first maintenance frame 21, and the second maintenance frame 22 can move away from or toward the first maintenance frame 21 through the lifting assembly 23.

[0052] The second inspection frame 22 is adjusted by the lifting component 23 to move away from or toward the first inspection frame 21, so that areas at different heights of the poured section can be inspected.

[0053] A ladder 25 is provided between the second maintenance frame 22 and the first maintenance frame 21. One end of the ladder 25 is connected to the first maintenance frame 21, and the other end of the ladder 25 passes through an opening in the second maintenance frame 22. Both ends of the first maintenance frame 21 are connected to a first inverted U-shaped gantry 51 and a second inverted U-shaped gantry 52, respectively, which provide support for the first maintenance frame 21. The ladder 25's length between the first and second maintenance frames 21 is adjustable as the second maintenance frame 22 moves.

[0054] In some embodiments, the lifting assembly 23 includes a first channel steel and a second channel steel. The first channel steel is connected to the first maintenance frame 21, and the second channel steel is connected to the second maintenance frame 22. The end of the second channel steel away from the second maintenance frame 22 is located in the groove of the first channel steel, and the second channel steel is slidably fitted to the first channel steel. Both the first and second channel steels are provided with multiple limiting holes, which are evenly distributed along the length of the first channel steel and correspond to each other. Limiting elements are inserted into the limiting holes of the first and second channel steels. Specifically, the limiting holes can be threaded holes, and the limiting elements can be bolts. When the second channel steel slides along the groove of the first channel steel to the target position, multiple bolts are screwed into the multiple threaded holes, so that one end of the first and second channel steels has multiple connection points, making the connection more secure. The sliding fit between the first and second channel steels is suitable for scenarios where a construction platform 3 needs to be erected at any time on a construction site, offering low cost and convenient assembly / disassembly.

[0055] In some embodiments, the construction platform 3 includes a support frame 31, a support plate 32, and a first construction frame 33. The support frame 31 is connected to the side formwork of the concrete casting, and the side formwork of the concrete casting provides support for the support frame 31. The support plate 32 is connected to the support frame 31, and multiple support plates 32 are provided, which are spaced apart along the height direction of the bridge 1. The support frame 31 includes an outer support and an inner support distributed along the width direction of the bridge 1, and the support plate 32 is located between the outer support and the inner support. Figure 2 As shown, the support plate 32 extends along the length of the bridge 1, and the support plate 32 is connected to the outer support and the inner support on both sides of the width of the bridge 1, so that both long sides of the support plate 32 are connected to the support frame 31, which increases the connection area between the support plate 32 and the support frame 31. At the same time, the outer support can also serve as a protective railing.

[0056] The first construction frame 33 is located above the support plate 32. There are two first construction frames 33, each connected between the second inverted U-shaped gantry 52 and the third inverted U-shaped gantry 53. The two first construction frames 33 are distributed along the height direction of the bridge 1. The two ends of the first construction frame 33 are connected to the second inverted U-shaped gantry 52 and the third inverted U-shaped gantry 53 respectively, making the first construction frame 33 more stable.

[0057] Among them, such as Figure 2 As shown, two adjacent support plates 32, adjacent support plates 32 and the first construction frame 33, and two adjacent first construction frames 33 are all connected by inclined ladders 34. Workers can switch construction positions between multiple support plates 32 and the first construction frames 33 using the inclined ladders 34.

[0058] In some embodiments, the support plate 32 is provided with an opening for people to pass through, and the inclined ladder 34 between two adjacent support plates 32 is located inside the outer support. Both ends of each inclined ladder 34 are located at the edge of the opening. Compared with the inclined ladder 34 being set directly outside the support plate 32, the inclined ladder 34 is located inside the outer support, and the outer support can protect the workers moving on the inclined ladder 34.

[0059] In some embodiments, a second construction frame 35 is provided at the end of the casting section away from the already cast section. The second construction frame 35 is located on one side of the casting section along the length of the bridge 1. The second construction frame 35 is connected to the inverted U-shaped gantry and extends along the width of the bridge 1. The second construction frame 35 intersects with the first construction frame 33. The construction platform 3 can provide points for workers to walk and carry out construction from multiple angles of the bridge 1.

[0060] In some embodiments, such as Figure 1 As shown, bridge 1 includes an integrally formed support portion 11 and a bridge deck 12, wherein the width of the support portion 11 is smaller than the width of the bridge deck 12. Figure 3 As shown, the inverted U-shaped gantry includes a U-shaped frame 54 and two connecting beams 55. The two free ends of the U-shaped frame 54 extend along its length to form a connecting beam 55. The U-shaped frame 54 is connected to the main beam on the bridge deck 12. The connecting beams 55 extend below the support portion 11 and are located on the outside of the support portion 11. The maintenance platform 2, construction platform 3, and connecting platform 4 are connected to the U-shaped frame 54 via the connecting beams 55. This design minimizes the space occupied by the maintenance platform 2 and construction platform 3 in the width direction of the bridge 1, preventing them from occupying too much space and affecting traffic and other related operations in the surrounding environment.

[0061] In some embodiments, guardrails are provided on the side of the first maintenance frame 21 and the second maintenance frame 22 away from the bridge 1. Guardrails are also provided on the side of the first construction frame 33 and the second construction frame 35 away from the bridge 1. The guardrails protect construction workers from falling off the construction platform 3 and the maintenance platform 2.
