[0031] Combined with reference Figure 1 and Figure 2 In the first embodiment of the present application, a modular assembled mobile caisson construction work platform is provided, which includes a plurality of basic units 01, wherein the basic unit 01 includes an outer frame 1, a safety guardrail 3, a ladder 2 and a top plate; the outer frame 1 includes a plurality of upper beams 12, a plurality of lower beams 13 and a plurality of columns 11, and the plurality of upper beams 12 are interconnected to form the top surface of the outer frame 1; the plurality of lower beams 13 are interconnected to form the bottom surface of the outer frame 1; the plurality of columns 11 are connected to the top surface of the outer frame 1 at one end and to the bottom surface of the outer frame 1 at the other end to form the side surface of the outer frame 1; the safety guardrail 3 is arranged on the bottom surface of the outer frame 1; the top plate is arranged on the top surface of the outer frame 1; the ladder 2 is arranged on the bottom surface of the outer frame 1, and the ladder 2 is used to be connected to the top plate.

[0032] The outer frame 1 is composed of a plurality of upper crossbeams 12, a plurality of lower crossbeams 13, and a plurality of upright posts 11, which can be easily transported to a suitable location for assembly. The outer frame 1 can be a stable structure such as a rectangular parallelepiped, a cube, or a triangular prism to ensure the stability of the outer frame 1. The number of upper crossbeams 12, lower crossbeams 13, and upright posts 11 is at least three. When the number of upper crossbeams 12, lower crossbeams 13, and upright posts 11 is three, a stable triangular prism can be formed.

[0033] Specifically, the outer frame 1 in this embodiment is a rectangular parallelepiped; wherein, there are four upper cross beams 12, which are connected to each other to form the top surface of the outer frame 1; there are four lower cross beams 13, which are connected to each other to form the bottom surface of the outer frame 1, corresponding to the top surface of the outer frame 1 formed by the upper cross beams 12; there are four columns 11, one end of which is connected to the top surface of the outer frame 1, and the other end is connected to the bottom surface of the outer frame 1, constituting the side surface of the outer frame 1, and the side surface of the outer frame 1 specifically includes the left side, the right side, the front side and the rear side door.

[0034] The top plate 5 is arranged on the top surface of the outer frame 1, so that the staff can climb up to the top plate 5 from the inside of the outer frame 1 through the ladder 2 to perform mobile operations, thereby expanding the range of activities of the staff.

[0035] The modular assembled mobile caisson construction work platform of this embodiment includes several basic units 01. The basic unit 01 is composed of an outer frame 1, a safety guardrail 3, a ladder 2 and a top plate 5. It can be assembled and assembled, which is convenient for transportation and lifting. After assembly, it can be directly sunk as a caisson work platform. The components of the basic unit 01 can all adopt steel structures, which reduces the weight of the caisson work platform, facilitates lifting, and simplifies the construction and dismantling process, reducing costs; and is provided with a guardrail and a ladder 2, which facilitates the staff to move around in the basic unit 01 for work, further reducing safety risks and improving the safety of the staff; at the same time, several basic units 01 can be vertically stacked and horizontally arranged in parallel, that is, the basic unit 01 can be built as a basic module combination, which expands the staff's range of movement and facilitates work.

[0036] The modular assembled mobile caisson construction work platform of this embodiment can be used in the construction process of the staff. Specifically, the assembled basic unit 01 can be lifted to the required working position of the caisson by a mobile crane. After placement, the staff can reach the area where the work is required through the ladder 2 set in the basic unit 01 to carry out support and membrane removal operations. After the staff completes the work, the basic unit 01 is lifted to the next work area by a mobile crane until the work is completed, and then the basic unit 01 is dismantled and transported to the next caisson position for assembly and use or transported to a warehouse for storage and standby; in this process, due to the presence of the safety guardrail 3 and the ladder 2, the safety of the staff is greatly guaranteed; the modular assembled mobile caisson construction work platform of this embodiment can be quickly assembled, and through flexible movement and efficient turnover through lifting, it greatly improves work efficiency, ensures the personal safety of the staff, and reduces construction costs.

[0037] In some embodiments, the basic unit 01 further includes a bottom plate 4, which is disposed at the bottom of the outer frame 1, and the ladder 2 is located on the bottom plate 4; a manhole 51 is provided on the top plate 5, and the ladder 2 connects the manhole 51 and the bottom plate 4. The provision of the bottom plate 4 makes the bottom of the basic unit 01 flat and stable, and can better fix the position of the ladder 2, preventing workers from getting injured while climbing the ladder 2. Specifically, the ladder 2 is located below the manhole 51, connecting the manhole 51 with the bottom plate 4, so that workers can reach the top plate 5 through the manhole 51 to perform work. Both the bottom plate 4 and the top plate 5 can be made of stainless steel with anti-slip patterns to prevent workers from falling.

[0038] Combined with reference Figure 2 and Figure 3 To prevent workers from falling out of the outer frame 1 and getting injured, in some embodiments, the safety guardrail 3 includes a first safety guardrail, a second safety guardrail, a third safety guardrail, and a fourth safety guardrail. The first safety guardrail is located on the rear side of the outer frame 1, the second safety guardrail is located on the front side of the outer frame 1, the third safety guardrail is located on the left side of the outer frame 1, and the fourth safety guardrail is located on the right side of the outer frame 1. In other words, the safety guardrail 3 can be added to one side, both sides, or all four sides of the outer frame 1, thereby improving the protection of workers and reducing operational risks.

[0039] In some embodiments, connecting ear plates 111 are provided at the top and bottom ends of the column 11. The column 11 can be hoisted and transported through the connecting ear plates 111 provided on the column 11, and the assembled basic unit 01 can also be hoisted through the connecting ear plates 111 provided on the column 11. At the same time, the position of the basic unit 01 can also be fixed through the connecting ear plates 111.

[0040] Due to the requirements of the construction work, the caisson operation platform may need to be built deeper underground. In some embodiments, the arrangement of several of the basic units 01 includes a vertical stacking arrangement. That is, the height of the caisson operation platform can be increased by vertically stacking the basic units 01, thereby enabling it to be built deeper underground for operations. Specifically, a double-layer unit is composed of two vertically stacked basic units 01, and a multi-layer unit is composed of three or more basic units 01 arranged in an upper and lower manner.

[0041] In the basic units 01 corresponding to the vertical stacking, the bottom surface of the outer frame 1 of the basic unit 01 located above is fitted and connected to the top surface of the outer frame 1 of the basic unit 01 located below; specifically, the connecting ear plate 111 at the bottom end of the column 11 of the basic unit 01 located above is fitted and connected to the connecting ear plate 111 at the top end of the column 11 of the basic unit 01 located below.

[0042] Combined with reference Figure 4 and Figure 5 The first double-layer unit 02 is obtained by vertically stacking two basic units 01. The basic units 01 each include an outer frame 1, a safety guardrail 3, a ladder 2, a bottom plate 4 and a top plate 5. The bottom plate 4 is located on the bottom surface of the outer frame 1 formed by the lower crossbeam 13, and the top plate 5 is located on the top surface of the outer frame 1 formed by the upper crossbeam 12; the ladder 2 is located on the bottom plate 4 and connects the manhole 51 set on the bottom plate 4 and the top plate 5; the top and bottom ends of the column 11 are both provided with connecting ear plates 111; the connecting ear plate 111 at the bottom end of the column 11 of the upper basic unit 01 is fitted and connected with the connecting ear plate 111 at the top end of the column 11 of the lower basic unit 01.

[0043] The only difference between the basic unit 01 located above and the basic unit 01 located below is that the safety guardrail 3 of the basic unit 01 located above includes a first guardrail 31, a second guardrail 32, a third guardrail 33 and a fourth guardrail 34, and the first guardrail 31, the second guardrail 32, the third guardrail 33 and the fourth guardrail 34 are respectively located on the rear side, front side, left side and right side of the outer frame 1; while the guardrail of the basic unit 01 located below only includes the second guardrail 32 located on the front side of the outer frame 1.

[0044] Combined with reference Figure 6 and Figure 7 The second double-layer unit 03 is obtained by vertically stacking two basic units 01. The basic units 01 each include an outer frame 1, a safety guardrail 3, a ladder 2, a bottom plate 4 and a top plate 5. The bottom plate 4 is located on the bottom surface of the outer frame 1, and the top plate 5 is located on the top surface of the outer frame 1; the ladder 2 is located on the bottom plate 4 and is connected to the manhole 51 set on the bottom plate 4 and the top plate 5; the top and bottom ends of the column 11 are both provided with connecting ear plates 111; the connecting ear plate 111 at the bottom end of the column 11 of the basic unit 01 located above is fitted and connected with the connecting ear plate 111 at the top end of the column 11 of the basic unit 01 located below. The basic unit 01 located above is exactly the same as the basic unit 01 located below and corresponds to each other. The safety guardrail 3 of the basic unit 01 includes a first guardrail 31, a second guardrail 32, a third guardrail 33 and a fourth guardrail 34. The first guardrail 31, the second guardrail 32, the third guardrail 33 and the fourth guardrail 34 are respectively located on the rear side, front side, left side and right side of the outer frame 1.

[0045] In some embodiments, the vertically stacked columns 11 of adjacent basic units 01 are connected by the connecting lugs 111. Adjacent basic units 01 are preferably basic units 01 of corresponding cross-sectional sizes, i.e., the bottom surfaces of the upper basic units 01 correspond to the bottom surfaces of the lower basic units 01, and can be directly connected by the connecting lugs 111 of the columns 11, which can prevent partial structural protrusion and improve the connection stability between the basic units 01.

[0046] In some embodiments, the basic unit 01 further includes a connecting bolt 112, which is located on the connecting lug 111. The connecting lug 111 is provided with a hole corresponding to the connecting bolt 112. The connecting bolt 112 is engaged with the corresponding hole on the connecting lug 111, which can improve the stability of the connection and facilitate on-site assembly and construction.

[0047] Combined with reference Figure 8 In some embodiments, the modular assembled mobile caisson construction platform further includes a top unit 04, which includes a top guardrail 9, fixing bolts 61, and an I-beam 6. The top guardrail 9 is disposed on top of the basic unit 01, and the fixing bolts 61 are connected to the basic unit 01. The top guardrail 9 is connected to the I-beam 6 via the fixing bolts 61. When the caisson platform needs to continue sinking a short distance, specifically, when the distance required is less than the height of the basic unit 01, the cost of further stacking basic units 01 is high. In this case, the top unit 04 can be stacked on the basic unit 01 or multi-layer units, which can not only meet operational needs, but also reduce construction costs and improve construction efficiency.

[0048] The I-beam 6, fixing bolts 61, and top guardrail 9 can be directly hoisted onto the top of the basic unit 01 or the top of the multi-story unit. The top guardrail 9 can then be connected to the top of the basic unit 01 or the top of the multi-story unit via the I-beam 6 and fixing bolts 61 for assembly. This simple construction method offers low hoisting weight, ease of hoisting difficulty, and minimal safety risks. The size of the fixing bolts 61 corresponds to the holes in the connecting lugs 111, meaning that the fixing bolts 61 and the holes in the connecting lugs 111 allow the basic unit 01 and the top unit 04 to be connected and secured to each other.

[0049] In some embodiments, the I-beam 6 is provided with a detachable lifting ring 62. The provision of the lifting ring 62 facilitates the installation of the I-beam 6. Specifically, the I-beam 6 can be lifted using the lifting ring 62 and then removed after transporting to a specific location. After assembling the I-beam 6, fixing bolts 61, and top guardrail 9, the top unit can be lifted to the desired location using the lifting ring 62.

[0050] In some embodiments, the I-beams 6 are arranged in a pair, one in front of the top guardrail 9 and one behind the top guardrail 9. After assembling the I-beams 6, fixing bolts 61, and top guardrail 9, the pair of I-beams 6 ensures stability during hoisting using the lifting rings 62. Specifically, each I-beam 6 is provided with a lifting ring 62 at both ends, further enhancing its stability during hoisting.

[0051] The holes for some construction operations are large in size, and several caisson work platforms need to be placed at the edge of the holes to facilitate the workers' operations and ensure their safety; therefore, in some embodiments, the arrangement of several of the basic units 01 includes horizontal parallel settings, thereby expanding the workers' working range in the horizontal direction.

[0052] Furthermore, in some embodiments, the top unit 04 is positioned on top of the horizontally arranged basic units 01, connecting the horizontally arranged basic units 01. The top unit 04 can be used to connect the horizontally arranged basic units 01 to each other, making it easier for workers to move between adjacent basic units 01. Furthermore, a double-layer unit or a multi-layer unit composed of several vertically stacked basic units 01 can be arranged horizontally in parallel, and the top unit 04 can then connect the basic units 01 at the top of the horizontally arranged double-layer or multi-layer units.

[0053] Preferably, a top unit 04 is set on top of the basic units 01, double-layer units or multi-layer units that are arranged horizontally and in parallel at the same height, which facilitates the construction of the top unit 04 and ensures that the top unit 04 is level and stable, which is beneficial for workers to carry out operations after reaching the top unit 04.

[0054] In some embodiments, the top unit 04 further includes a connecting plate 8 , which is used to connect the tops of adjacent basic units 01 . Specifically, the connecting plate 8 is connected to the top plates 5 of adjacent basic units 01 .

[0055] In some embodiments, the top unit 04 further includes a connecting guardrail 7, which is interconnected with the top guardrail 9. There are gaps between the horizontally arranged basic units 01, and the connecting guardrail 7 is used to connect the top guardrails 9 set on the tops of different basic units 01 of the top unit 04 to ensure the safety of workers during the movement of adjacent basic units 01. Specifically, the connecting guardrail 7 is a pair, namely a first connecting guardrail 71 and a second connecting guardrail 72, and the first connecting guardrail 71 and the second connecting guardrail 72 are placed on the rear and front sides of the connecting plate 8; the connecting guardrail 7 is interconnected with the top guardrail 9 to form a closed guardrail circle to ensure that workers can pass through the connecting plate 8 smoothly.

[0056] The composite structure composed of the basic units 01, double-layer units or multi-layer units arranged horizontally and connected to each other through the top unit 04 is a combined unit 05. The combined unit 05 composed of the first double-layer unit 02, the second double-layer unit 03 and the top unit 04 is as follows: Figure 9 and Figure 10 The top unit 04 includes several sets of top guardrails 9, which may include a first top guardrail 91, a second top guardrail 92, a third top guardrail 93 and a fourth top guardrail 94; the first top guardrail 91, the second top guardrail 92, the third top guardrail 93 and the fourth top guardrail 94 may be respectively arranged at the rear, front, left and right edges of the top plate 5 of the basic unit 01 at the top of the first double-layer unit 02 and the second double-layer unit 03; the basic unit 01 at the top of the first double-layer unit 02 and the second double-layer unit 03 is connected by a connecting plate 8. 1 are interconnected; the first connecting guardrail 71 and the second connecting guardrail 72 are respectively provided on the front and rear sides of the connecting plate 8; the top unit 04 is connected and fixed to the connecting lug 111 of the base unit 01 via fixing bolts 61. Specifically, the top of the columns 11 of the base unit 01 at the top of the first double-layer unit 02 and the second double-layer unit 03 each have four connecting lugs 111, and eight fixing bolts 61 are provided accordingly; a pair of I-beams 6 are provided, respectively, in front and rear of the top guardrail 9, with fixing bolts 61 located on the I-beams 6. The fixing bolts 61 can be optionally U-shaped hoops that can cooperate with the connecting bolts 112 to connect and fix the connecting lugs 111.

[0057] All components of the above-mentioned basic unit 01 and top unit 04 may be made of steel structure, such as stainless steel, which not only ensures the rigidity and hardness of the components but also reduces the weight of the components, making them easier to assemble and transport.

[0058] The modular assembled mobile caisson construction work platform of the present application can obtain a double-layer unit or a multi-layer unit by vertically stacking several basic units 01, and can also set a top-level unit 04 on the basic unit 01. At the same time, several double-layer units or multi-layer units that have been vertically stacked can be connected and set through the top-level unit 04 to obtain a combined unit, which is suitable for different caisson construction conditions and meets the requirements of the construction conditions for the caisson construction work platform; therefore, the modular assembled mobile caisson construction work platform of the present application can achieve the effect of being suitable for different construction conditions through modular assembly of basic units 01 and top-level units 04, has modular and assembled characteristics, and can be moved by a crane for operation when it is built for use, and has movable characteristics.

[0059] In summary, the present application provides a modular assembled mobile caisson construction work platform, which includes several basic units. The basic unit is composed of an outer frame, a safety guardrail, a ladder and a top plate. It can be assembled and assembled, which is convenient for transportation and lifting. After assembly, it can be directly sunk as a caisson work platform. The components of the basic unit can all adopt steel structure, which reduces the weight of the caisson work platform, facilitates lifting, and simplifies the construction and dismantling process, reducing costs; and guardrails and ladders are provided to facilitate staff to move within the basic unit to carry out operations, further reducing safety risks and improving safety protection for staff; at the same time, several basic units can be stacked vertically and arranged horizontally in parallel, which expands the staff's range of movement and facilitates operations.
