Description

Technical Field

[0001] This utility model relates to the field of construction platform technology, and in particular to a temporary working platform for offshore berthing platforms. Background Technology

[0002] Offshore berthing platforms play a vital role in near-shore engineering, port terminals, and offshore operation areas, typically used for ship berthing, cargo loading and unloading, and operational support. However, after prolonged operation or exposure to external impacts (such as accidental collisions), berthing platforms may experience structural tilting or localized damage. When a platform is damaged and requires dismantling or repair, construction personnel must enter the confined space beneath the berthing platform to perform the work.

[0003] The traditional solution is to erect scaffolding from the ground to the target location and then install a temporary working platform. However, since offshore berthing platforms are located in the sea, erecting scaffolding from the bottom of the pile foundation is a large undertaking, affecting work efficiency. Furthermore, if the berthing platform is damaged, it may shift relative to the steel pipe piles at its base, potentially causing the piles to tilt or collapse, further restricting the working space and making it impossible to erect scaffolding from the bottom of the piles during construction. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of traditional temporary work platforms, which are limited in space and cannot be used to build temporary work platforms for damaged offshore berthing platforms, and to provide a temporary work platform for offshore berthing platforms.

[0005] In a first aspect, this utility model provides a temporary working platform for offshore berthing platforms, comprising:

[0006] A hanging plate, located on the top surface of the berthing platform, the length of the hanging plate is not less than the width of the berthing platform, and the hanging plate is movable relative to the berthing platform;

[0007] Two hanging ladders are symmetrically arranged at both ends of the hanging plate, and the hanging ladders extend downward from the hanging plate;

[0008] Two suspended platforms are respectively attached to the end of the hanging ladder away from the hanging plate, and the suspended platforms extend toward the pile foundation;

[0009] A lower working platform is located below the berthing platform and is fixedly connected to the pile foundation;

[0010] A fixed ladder is fixed to the mooring platform and is connected to the lower working platform.

[0011] The present invention provides a temporary working platform for offshore berthing platforms. The hanging plate can move relative to the berthing platform, allowing construction workers to freely adjust the position of the hanging plate according to the damage to the berthing platform and select the most suitable working point. It is convenient for construction workers to go down to the suspended platform via a hanging ladder and work on the suspended platform to weld the lower working platform to the pile foundation.

[0012] Compared to traditional work platforms that require scaffolding to be erected from the bottom of the pile foundation, the temporary work platform for offshore berthing platforms provided by this invention allows construction workers to work on a suspended platform during the installation of the lower work platform, which is then directly and securely connected to the berthing platform. After the lower work platform is installed, construction workers can directly access it via a fixed ladder, facilitating their movement. This temporary work platform for offshore berthing platforms avoids the cumbersome process of erecting scaffolding from the bottom, significantly reducing the workload, lowering the difficulty of the work, making it more suitable for repairing damaged berthing platforms, and greatly improving work efficiency.

[0013] Preferably, the lower working platform includes:

[0014] Several supports, the top surfaces of which are all located on the same horizontal plane, and each pile foundation is fixedly connected to one of the supports;

[0015] The walkway slab is located on the top surface of the support frame, and the distance between the walkway slab and the bottom surface of the mooring platform is no more than 1.7m. The fixed ladder is connected to the walkway slab.

[0016] Each pile foundation is supported by only one bracket, minimizing space occupation while ensuring stability and providing more working space for subsequent installation of walkway slabs and construction workers. Since the space beneath the berthing platform is limited after damage (e.g., pile foundation displacement, tilting, or even overturning), the walkway slabs are no more than 1.7m from the bottom of the berthing platform. This height makes full use of vertical space, allowing construction workers to work within a limited area.

[0017] Preferably, the system further includes a ladder reinforcement beam, which is obliquely intersecting the fixed ladder. One end of the ladder reinforcement beam is fixedly connected to the bottom surface of the mooring platform, and the other end of the ladder reinforcement beam is obliquely intersecting the fixed ladder. A support beam is installed between the ladder reinforcement beam and the fixed ladder, and the top surface of the support beam and the top surface of the bracket are both located on the same horizontal plane.

[0018] This structural design features an obliquely intersecting design between the ladder reinforcement beam and the fixed ladder. The ladder reinforcement beam acts as a "diagonal brace," significantly enhancing the stability of the fixed ladder. A support beam is installed between the ladder reinforcement beam and the fixed ladder, with its top surface flush with the top surface of the support frame, ensuring the horizontal consistency of the lower work platform. This design not only provides additional support for the walkway slabs but also provides lateral support for the fixed ladder, further improving the structural stability.

[0019] Preferably, the walkway slab includes several long slabs, the long slabs connecting two adjacent supports, and the long slabs also connecting the support beam and the support adjacent to the support beam.

[0020] The long plank forms a multi-point support structure by connecting two adjacent supports and support beams. The supports are fixed to the pile foundation, providing a solid foundation, while the support beams are connected to the ladder reinforcement beams and fixed ladders, further enhancing the support capacity and ensuring that the walkway plank can stably bear the weight of construction workers and the load during operation.

[0021] Preferably, the walkway slab further includes a plurality of short slabs, the short slabs connecting two adjacent long slabs.

[0022] This structural design connects adjacent long planks with short planks to form a continuous walking path, facilitating the movement and work of construction workers on the walkway.

[0023] Preferably, the support includes a crossbeam and a diagonal brace, the diagonal brace intersecting the crossbeam at an angle, one end of the diagonal brace being fixedly connected to the pile foundation, the other end of the diagonal brace being fixedly connected to the crossbeam, one end of the crossbeam being fixedly connected to the pile foundation, the other end of the crossbeam being cantilevered, and the walkway slab being located on the top surface of the crossbeam.

[0024] The support structure forms a triangular structure with crossbeams and diagonal braces. One end of the diagonal brace is fixed to the pile foundation, and the other end is connected to the crossbeam. One end of the crossbeam is also fixed to the pile foundation, which effectively transfers the load on the walkway slab to the pile foundation, significantly reduces the bending stress of the crossbeam, and ensures that the platform can withstand the weight of workers and equipment without excessive deformation or failure.

[0025] Preferably, the crossbeam is arranged around the pile foundation.

[0026] The crossbeams are arranged around the pile foundation, forming a ring or partial ring connection, which can more evenly distribute the load from the walkway slabs and construction workers, and significantly improve the overall stability of the support.

[0027] Preferably, there are four crossbeams, and the included angle between the crossbeams is 90°.

[0028] Four crossbeams are evenly distributed around the pile foundation at a 90° angle, forming a cross-shaped support structure. This orthogonal layout ensures that the load from the walkway slab can be evenly transferred to the pile foundation, effectively avoiding local stress concentration and significantly improving the overall stability of the support.

[0029] Preferably, the system also includes a guardrail, which is installed on the bracket and is used to protect the walkway slab.

[0030] Offshore working environments are often characterized by slippery conditions and swaying. Installing guardrails around the walkways provides a physical barrier for construction workers, effectively preventing them from falling while walking or working on the walkways and ensuring their safety.

[0031] Preferably, the guardrail includes a plurality of vertical bars and a plurality of horizontal bars, the vertical bars are fixedly installed on the horizontal beam, the horizontal bars are fixedly connected to the vertical bars, and the vertical bars are perpendicular to the horizontal bars.

[0032] With this structural design, the vertical bars are directly fixed to the horizontal beams. The stable connection between the horizontal beams and the pile foundation ensures the guardrail has high resistance to overturning and deformation. The vertical connection between the horizontal and vertical bars further enhances the overall rigidity of the guardrail, forming a stable frame structure capable of withstanding external forces from workers leaning against it or accidental impacts, thus further enhancing the safety of this temporary work platform used for offshore berthing platforms.

[0033] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0034] 1. This utility model provides a temporary working platform for offshore berthing platforms. The hanging plate can move relative to the berthing platform, allowing construction workers to freely adjust the position of the hanging plate according to the damage to the berthing platform and select the most suitable working point. It is convenient for construction workers to go down to the suspended platform via a hanging ladder and work on the suspended platform to weld the lower working platform to the pile foundation.

[0035] 2. This utility model provides a temporary working platform for offshore berthing platforms. During the installation of the lower working platform, construction workers can work on a suspended platform, with the lower working platform directly and fixedly connected to the berthing platform. After the lower working platform is installed, construction workers can directly access it via a fixed ladder, facilitating their movement up and down.

However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0045] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.

[0050] Example 1

[0051] When a berthing platform at sea is damaged (e.g., due to a ship collision), it may experience structural tilting or localized damage. Traditional temporary work platforms, which require erecting scaffolding from the bottom of the pile foundation, involve a large amount of work. Furthermore, the damaged pile foundation may shift, tilt, or even overturn, limiting the working space and making it impossible to set up a traditional temporary work platform. Therefore, there is an urgent need for a temporary work platform suitable for damaged berthing platforms.

[0052] This embodiment provides a temporary working platform for offshore berthing platforms, such as... Figure 1 , Figure 2 , Figure 3( Figure 1 , Figure 2 The status shown (the operating platform is not yet installed) includes:

[0053] Hanging plate 1 is located on the top surface of the berthing platform 100. In this embodiment, hanging plate 1 can be made of channel steel by welding.

[0054] like Figure 2 As shown, the length of the hanging plate 1 is not less than the width of the berthing platform 100, and the hanging plate 1 can move relative to the berthing platform 100.

[0055] Specifically, for example, two parallel slide rails can be set along the length of the berthing platform 100, and the hanging plate 1 can slide along the slide rails; or the hanging plate 1 can be moved directly from the top of the berthing platform 100 by manpower or with the help of other tools, thereby changing the position of the hanging plate 1.

[0056] Two hanging ladders 2 are symmetrically arranged at both ends of the hanging plate 1, and the hanging ladders 2 extend downward (towards the sea surface) from the hanging plate 1.

[0057] Two suspended platforms 3 are respectively attached to the end of the hanging ladder 2 away from the hanging plate 1, and the suspended platforms 3 extend toward the pile foundation 200 (specifically, as shown in the figure). Figure 2 For example, Figure 2 The left-side suspended platform 3 extends to the right; Figure 2 (The right-side suspended platform 3 extends to the left). When in use, the hanging plate 1 can be moved to the position of the pile foundation 200. Construction workers can go down to the suspended platform 3 through the hanging ladders 2 on both sides of the hanging plate 1 and carry out construction inside the suspended platform 3, welding the lower working platform to the pile foundation 200.

[0058] The lower working platform is located below the berthing platform 100 and is fixedly connected to the pile foundation 200.

[0059] Fixed ladder 4 is fixed to the berthing platform 100. Specifically, as follows: Figure 1 , Figure 3 As shown, the fixed ladder 4 can be fixedly installed on the short side of the berthing platform 100, and the fixed ladder 4 is connected to the lower working platform.

[0060] The temporary work platform provided in this embodiment for the offshore berthing platform 100 has a hanging plate 1 that can move relative to the berthing platform 100, allowing construction workers to freely adjust the position of the hanging plate 1 according to the damage to the berthing platform 100 and select the most suitable work point. This facilitates construction workers to descend to the suspended platform 3 via the hanging ladder 2 and work on the suspended platform 3 to weld the lower work platform to the pile foundation 200.

[0061] Compared to traditional work platforms that require scaffolding to be erected from the bottom of the pile foundation 200, the temporary work platform for the offshore berthing platform 100 provided in this embodiment allows construction workers to work on the suspended platform 3 during the installation of the lower work platform, which is then directly and securely connected to the berthing platform 100. After the lower work platform is installed, construction workers can directly access it via a fixed ladder 4, facilitating their movement. This temporary work platform for the offshore berthing platform 100 avoids the cumbersome process of erecting scaffolding from the bottom, significantly reducing the workload and difficulty of the work. It is more suitable for repairing damaged berthing platforms 100 and greatly improves work efficiency.

[0062] Example 2

[0063] Based on Example 1, such as Figure 3 , Figure 4 , Figure 5 As shown, the temporary working platform for offshore berthing platforms provided in this embodiment includes the following:

[0064] Several supports 51 are provided, with their top surfaces all on the same horizontal plane. Each pile foundation 200 is fixedly connected to only one support 51. By installing only one support 51 on each pile foundation 200, space occupation is minimized while ensuring stability, providing a larger working space for the subsequent erection of walkway slabs 52 and for construction workers.

[0065] Furthermore, such as Figure 5 As shown, the support 51 includes a crossbeam 511 and a diagonal brace 512. The diagonal brace 512 is oblique to the crossbeam 511. One end of the diagonal brace 512 is fixedly connected to the pile foundation 200, and the other end of the diagonal brace 512 is fixedly connected to the crossbeam 511. One end of the crossbeam 511 is fixedly connected to the pile foundation 200, and the other end of the crossbeam 511 is cantilevered. The walkway slab 52 is located on the top surface of the crossbeam 511.

[0066] In this embodiment, the crossbeam 511 can specifically be a double-layered No. 5 angle iron. The support 51 forms a triangular structure through the crossbeam 511 and the diagonal brace 512. One end of the diagonal brace 512 is fixed to the pile foundation 200, and the other end is connected to the crossbeam 511. One end of the crossbeam 511 is also fixed to the pile foundation 200, which effectively transfers the load on the walkway slab 52 to the pile foundation 200, significantly reduces the bending stress of the crossbeam 511, and ensures that the platform can withstand the weight of workers and equipment without excessive deformation or failure.

[0067] Furthermore, the crossbeams 511 are arranged around the pile foundation 200. For example, the number of crossbeams 511 can be four, six, or eight, and the crossbeams 511 can be arranged at equal intervals around the pile foundation 200. The arrangement of the crossbeams 511 around the pile foundation 200 forms a ring or partial ring connection, which can more evenly distribute the load from the walkway slab 52 and the construction personnel, and significantly improve the overall stability of the support 51.

[0068] Furthermore, such as Figure 5 As shown, there are four crossbeams 511, with an included angle of 90° between them. The four crossbeams 511 are evenly distributed around the pile foundation 200 at a 90° angle, forming a cross-shaped support structure. This orthogonal layout ensures that the load from the walkway slab 52 can be evenly transferred to the pile foundation 200, effectively avoiding local stress concentration and significantly improving the overall stability of the support 51.

[0069] Walkway slab 52 is located on the top surface of support 51. The distance between walkway slab 52 and the bottom surface of the mooring platform 100 is no more than 1.7m. Fixed ladder 4 is connected to walkway slab 52. Due to the limited space of the pile foundation 200 below the mooring platform 100 after damage (e.g., displacement, tilting, or even overturning of the pile foundation 200), the walkway slab 52 is no more than 1.7m from the bottom surface of the mooring platform 100. This height makes full use of vertical space, allowing construction personnel to work in a limited space.

[0070] Furthermore, such as Figure 3 , Figure 4 As shown, the temporary working platform for offshore berthing platforms provided in this embodiment also includes a ladder reinforcing beam 6. The ladder reinforcing beam 6 is obliquely intersecting with the fixed ladder 4. One end of the ladder reinforcing beam 6 is fixedly connected to the bottom surface of the berthing platform 100, and the other end of the ladder reinforcing beam 6 is obliquely intersecting with the fixed ladder 4. A support beam 7 is installed between the ladder reinforcing beam 6 and the fixed ladder 4. The top surface of the support beam 7 and the top surface of the bracket 51 are both located on the same horizontal plane. In this embodiment, the ladder reinforcing beam 6 can be an I-beam.

[0071] With this structural design, the ladder reinforcement beam 6 and the fixed ladder 4 are designed at an angle. The ladder reinforcement beam 6 acts like a "diagonal brace," significantly enhancing the stability of the fixed ladder 4. The support beam 7 is installed between the ladder reinforcement beam 6 and the fixed ladder 4, and its top surface is at the same level as the top surface of the bracket 51, ensuring the horizontal consistency of the lower working platform. This design not only provides additional support for the walkway slab 52 but also provides lateral support for the fixed ladder 4, further improving the structural stability.

[0072] Furthermore, such as Figure 4 , Figure 5As shown, the walkway slab 52 includes several long slabs 521 and several short slabs 522. Long slabs 521 connect two adjacent supports 51, and short slabs 522 connect two adjacent long slabs 521. The long slabs 521 also connect to the support beam 7 and the supports 51 adjacent to the support beam 7. Figure 5 For example, Figure 5 In the middle, two adjacent pile foundations 200 are fixedly installed with brackets 51. A long plate 521 connects the two adjacent brackets 51, and a short plate 522 is located on the long plate 521 and connects the two adjacent long plates 521. Figure 4 As shown, since the two pile foundations 200 on both sides of the fixed ladder 4 are far apart, the support beam 7 is used as the intermediate point. The long plate 521 on the left side of the fixed ladder 4 connects the support beam 7 and the left support 51; the long plate 521 on the right side of the fixed ladder 4 connects the support beam 7 and the right support 51.

[0073] The long plank 521 connects two adjacent supports 51 and the support beam 7, forming a multi-point support structure. The supports 51 are fixed to the pile foundation 200, providing a solid foundation, while the support beam 7 is connected to the ladder reinforcement beam 6 and the fixed ladder 4, further enhancing the support capacity and ensuring that the walkway slab 52 can stably bear the weight of construction workers and the load during operation. The short plank 522 connects the adjacent long planks 521, forming a continuous walking passage, facilitating the movement and operation of construction workers on the walkway slab 52.

[0074] Furthermore, the temporary work platform for offshore berthing platforms provided in this embodiment also includes a guardrail 8, which is installed on the support frame 51 and is used to protect the walkway slab 52. Specifically, as... Figure 3 , Figure 4 , Figure 5 As shown, the guardrail 8 includes several vertical bars 81 and several horizontal bars 82. The vertical bars 81 are fixedly installed on the horizontal beam 511, and the horizontal bars 82 are fixedly connected to the vertical bars 81, with the vertical bars 81 and horizontal bars 82 perpendicular to each other. The offshore working environment often presents unfavorable factors such as slipperiness and swaying. The guardrail 8, enclosing the walkway 52, provides a physical barrier for construction personnel, effectively preventing accidental falls while walking or working on the walkway 52, thus ensuring their safety. The vertical bars 81 are directly fixed to the horizontal beam 511, and the stable connection between the horizontal beam 511 and the pile foundation 200 ensures that the guardrail 8 has high resistance to overturning and deformation. The vertical connection between the horizontal bars 82 and the vertical bars 81 further enhances the overall rigidity of the guardrail 8, forming a stable frame structure capable of withstanding external forces from personnel leaning against it or accidental impacts, further enhancing the safety of this temporary working platform used for the offshore berthing platform 100.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
