Description

Technical Field

[0001] This utility model relates to the technical field of platform structures, specifically to a quick-assembly and disassembly temporary hatch coaming work platform. Background Technology

[0002] To improve cargo loading and unloading efficiency, modern shipbuilding typically employs large hatches, especially container ships. To ensure container access, the hatch size is usually identical to the cargo hold size. This hatch design results in only about one meter of passage space on the port and starboard sides of the deck, with similarly narrow passageways between cargo holds. A hatch coaming is a steel plate perpendicular to the ship's deck that surrounds the hatch. It is a crucial facility to prevent seawater from entering the cargo hold, increase the strength of the hatch, and reduce the risk of deck workers falling through open hatches. Hatch coamings are a typical and essential structure for container ships, bulk carriers, and general cargo ships, forming part of the main structural strength above the main deck in the cargo hold area. When hatch covers are not installed or during maintenance and repairs ashore, the effective space available for personnel operations and equipment / material storage in these types of ships is limited, leading to repeated temporary transport requiring significant crane time and resulting in low efficiency. To address the limited space for passage and storage in the cargo hold area of ​​a cargo ship's main deck, and to facilitate personnel operations and the placement of equipment and materials within the open hatch area, thereby saving crane usage time, reducing the occupation of passage space, and increasing the effective working area, a quick-installing hatch coaming temporary work platform is provided. Utility Model Content

[0003] To address the problems existing in the prior art, the present invention aims to provide a quick-assembly and disassembly temporary work platform for hatch coamings. This invention, based on the structural characteristics of the hatch coaming, allows for the rapid assembly and disassembly of a fixed platform to expand the upper deck working space. It eliminates the need for welding, reduces crane usage, and facilitates personnel operations and material storage.

[0004] The present invention discloses a quick-assembly and disassembly temporary hatch coaming operation platform, comprising a platform body, an adjustable support structure connected to the rear side of the platform body, the cross-section of the support structure being hook-shaped and adapted to the shape of the hatch coaming, a support structure provided below the platform body, the support structure being in close contact with the outer side of the hatch coaming, and the support structure cooperating with the support structure to allow the platform body to be erected on a plane extending outward from the upper surface of the hatch coaming.

[0005] In one embodiment, the support structure includes a first structural member, a second structural member, a third structural member, and a fourth structural member connected in sequence. The first and third structural members are horizontal plates, and the second and fourth structural members are vertical plates. One end of the first structural member is welded to the platform body. The first, second, third, and fourth structural members are all connected by an adjustment mechanism, which is used to adjust the effective length of each structural member.

[0006] In one embodiment, the adjustment mechanism includes a plurality of screw holes arranged along the length of one end of each structural member, and the other end of each structural member is adapted to the screw holes by bolts.

[0008] In one embodiment, the support structure includes support legs extending downward from the four corners of the platform body, and support rods are hinged to the lower front ends of the two sides of the platform body. The inner sides of the two support legs located at the rear end of the platform body are detachably connected to the other end of the support rod, and the top of the end of the support rod is also fitted with an anti-collision layer.

[0009] In one embodiment, the platform body includes a first plate, a second plate, and side frames on both sides. The first plate is fixedly connected to the side frames, and the second plate is slidably connected to the side frames. A U-shaped component is hinged to the bottom of the first plate, and the other end of the U-shaped component is hinged to a slider. The slider is slidably connected to a guide rail at the bottom of the second plate.

[0010] In one embodiment, support bars are arranged crosswise between the two second structural members. One end of each support bar is hinged to one of the two second structural members, and the other end of each support bar is hinged to a connector. The connector is slidably connected to the second structural members, and the middle parts of the two support bars are rotatably connected to each other. When the two second structural members are pulled apart, a fixing rod is also inserted and fixed between the two second structural members.

[0011] In one embodiment, the platform body is also provided with a detachable guardrail.

[0012] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

Detailed Implementation

[0018] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-3As shown, this utility model discloses a quick-assembly and disassembly temporary hatch coaming work platform, comprising a platform body 1, an adjustable support structure 2 connected to the rear side of the platform body 1, the cross-section of the support structure 2 being hook-shaped and adapted to the shape of the hatch coaming, and a support structure 3 provided below the platform body 1, the support structure 3 being in close contact with the outer side of the hatch coaming, and the support structure 3 cooperating with the support structure 2 to allow the platform body 1 to be erected on a plane extending outward from the upper surface of the hatch coaming. This utility model can quickly assemble and disassemble a fixed platform based on the structural characteristics of the hatch coaming to expand the upper deck working space. Through the cooperation of the support structure 2 and the support structure 3, the platform body 1 can be quickly installed and fixed without the need for welding or crane installation, shortening the assembly time. It can be effectively applied to personnel operations and material stacking during cargo loading and unloading, while reducing space occupation after disassembly and storage, thus improving production efficiency and reducing production costs.

[0021] Specifically, the support structure 2 includes a first structural member 21, a second structural member 22, a third structural member 23, and a fourth structural member 24 connected in sequence. The first and third structural members 21 and 23 are horizontal plates, while the second and fourth structural members 22 and 24 are vertical plates. One end of the first structural member 21 is welded to the platform body 1. The first, second, third, and fourth structural members 21, 22, 23, and 24 are all connected by an adjustment mechanism 25, which is used to adjust the effective length of each structural member. Figure 1 As shown, the support structure 2 generally consists of four structural components, which can be made of materials such as I-beams. The first structural component 21 and the third structural component 23 serve as horizontal beams, while the second structural component 22 and the fourth structural component 24 serve as vertical lugs, together forming a hook-like structure that surrounds the outer surface of the hatch coaming, thereby allowing the platform body 1 to extend horizontally outward along the deck and be fixed in place. Furthermore, the adjustment mechanism 25 used between the structural components includes multiple screw holes arranged along the length direction at one end of each structural component, and the other end of each structural component is fitted with the screw holes by bolts. The adjustment mechanism 25 forms multiple rows of screw holes at the end of one structural component, and then opens holes at the end of another structural component and inserts corresponding bolts for detachable connection. In this way, the effective length of each structural component can be adjusted by inserting different screw holes. That is, according to the different shapes of the outer surface of the hatch coaming, especially the different thicknesses of the corner plates, the support structure 2 can be adjusted to fit it according to the adjustment mechanism 25, thereby relatively fixing the platform body 1. In addition, the support structure 2 consists of two sets, which are respectively located on opposite sides of the platform body 1, so that the platform body 1 can achieve a better force balance effect after installation.

[0022] Furthermore, the support structure 3 includes support feet 31 extending downwards from the four corners of the platform body 1. Support rods 32 are also hinged to the lower front ends of the two sides of the platform body 1. The inner sides of the two support feet 31 located at the rear end of the platform body 1 are detachably connected to the other ends of the support rods 32, and the top of the end of the support rod 32 is also fitted with an anti-collision layer 33. The support structure 3 is used to further cooperate with the above-mentioned bracket structure 2 to erect the platform body 1, fix it and keep it horizontal. First, the support feet 31 allow the platform body 1 to be placed horizontally on the higher cargo in the outer cargo hold of the hatch coaming when it is not fixed in position. The support rods 32 can be adjusted and rotated from the front end of the support rod 32 so that the rear end of the support rod 32 abuts against the outer side of the hatch coaming, and the anti-collision layer 33 protects it from abrading the paint of the hatch coaming. In this way, the support rod 32 is fixedly connected to the rear support feet 31, thus supporting the platform body 1 and keeping it parallel to the deck.

[0023] In one embodiment, such as Figure 2 As shown, the platform body 1 includes a first plate 11, a second plate 12, and side frames 13 located on both sides. The first plate 11 is fixedly connected to the side frames 13, and the second plate 12 is slidably connected to the side frames 13. A U-shaped piece 14 is hinged to the bottom of the first plate 11, and the other end of the U-shaped piece 14 is hinged to the slider 15. The slider 15 is slidably connected to the guide rail 16 at the bottom of the second plate 12. The platform body 1 can adjust its overall width by overlapping or unfolding the first plate 11 and the second plate 12 to adapt to different application scenarios. The first plate 11 is fixed on the left side frame 13, while the second plate 12 can slide up and down the right side frame 13 by a distance approximately equal to the thickness of the first plate 11. When unfolded, after the second plate 12 is raised by rotating the U-shaped piece 14, the U-shaped piece 14 rotates from the bottom to the side to engage with the edge of the first plate 11, allowing the slider 15 to slide along the guide rail 16 and move the second plate 12 above the first plate 11. The two side frames 13 can also be further provided with structures that engage with the edges of the first plate 11 and the second plate 12. The process from overlapping to unfolding is the reverse of the above process.

[0024] And such Figure 3As shown, support bars 26 are arranged crosswise between the two second structural members 22. One end of each support bar 26 is hinged to one of the two second structural members 22, and the other end is hinged to a connector. The connector is slidably connected to the second structural member 22, and the middle parts of the two support bars 26 are rotatably connected to each other. When the two second structural members 22 are pulled apart, a fixing rod 27 is inserted and fixed between them. In order to maintain the stability of the support structure 2 while increasing the width of the platform body 1 after unfolding, the support structures 2 on both sides, especially the second structural members 22, are connected by support bars 26 to form a triangle to further enhance stability, similar to a lifting platform structure. The rotation and sliding of the two support bars 26 keep the two second structural members 22 parallel and stably unfolded or close together. When fully unfolded, a fixing rod 27 can be inserted between the two second structural members 22 to maintain their relative distance, which is equivalent to locking the position of the entire support mechanism 2. The fixing rod 27 can also be a telescopic rod or hydraulic rod with locking function, which is directly installed between the two second structural members 22.

[0025] In addition, the platform body 1 is also equipped with a detachable guardrail 4. The guardrail 4 can be composed of detachable rods and chains. Generally, four rods are inserted into the four corners of the platform body 1, and a chain is fastened between two adjacent rods to form a detachable guardrail 4, which can also serve as a planar passage and a protection for installation around holes.
