Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ships, in particular to a hatch enclosure safety guardrail device. Background Art
[0002] Among the three traditional main ships, container ships and bulk carriers are designed with large cargo holds, which are designed with hatch coamings and hatch covers. During the construction stage at the shipyard, the main hull is loaded first, and the hatch coaming is hoisted and welded. Generally, in order to ensure a good construction environment in the cargo hold, the hatch cover will not be hoisted until the major work in the cargo hold is basically completed. However, during the period between the installation of the hatch coaming and the hoisting of the hatch cover, there is a safety accident in which personnel fall into the cargo hold from the hatch coaming due to the lack of a good protective barrier device because there is no cargo hatch cover on the hatch coaming. As the ships being built become larger, the hatch coaming is often 20 meters away from the bottom of the cargo hold, which poses a serious safety hazard. Once a safety accident occurs, it will lead to irreparable losses.
[0003] Therefore, a hatch enclosure safety guardrail device is needed to solve the above problems. Utility Model Content

[0035] In the process of ship construction, in order to effectively protect the hatch coaming, eliminate safety hazards and avoid falling accidents, such as Figures 1-6 As shown, the utility model provides a hatch enclosure safety guardrail device. The hatch enclosure safety guardrail device comprises an eye plate 1, a guardrail column 2 and a blocking cable assembly 4.
[0036] Among them, a plurality of eyebolts 1 are arranged on the hatch coaming panel 200 at intervals along the extending direction of the hatch coaming panel 200; a plurality of guardrail columns 2 are arranged corresponding to the plurality of eyebolts 1 one by one, and the guardrail columns 2 are detachably sleeved on the eyebolts 1 in the vertical direction, and a plurality of eyelets 26 are arranged on the guardrail columns 2 at intervals. A plurality of arresting cable assemblies 4 are arranged between adjacent guardrail columns 2, and the arresting cable assemblies 4 are connected to the eyelets 26 on the adjacent guardrail columns 2.
[0037] During the process of shipbuilding, the eyebolt 1 is set on the hatch coaming panel 200, then the guardrail column 2 is installed, and the arresting cable assembly 4 is installed between the guardrail columns 2, so as to form a protection at the hatch coaming, which can prevent people from falling into the cargo hold, eliminate potential safety hazards, and avoid falling accidents. Moreover, since the guardrail column 2 is detachably connected to the eyebolt 1, it is convenient to quickly remove it during the subsequent installation of the cargo hatch cover 100, reducing the impact on subsequent construction.
[0038] In some embodiments, the guardrail column 2 includes a column body 21, and a first sealing plate 22 and a second sealing plate 23 are arranged at both ends of the column body 21. The uppermost eyelet 26 is fixedly arranged on the first sealing plate 22, and a docking assembly is arranged on the side of the second sealing plate 23 facing away from the first sealing plate 22, and the docking assembly is detachably connected to the eyebolt 1. By providing the first sealing plate 22, it is convenient to install the uppermost eyelet 26, and by providing the second sealing plate 23, it is convenient to arrange the docking assembly.
[0039] In some embodiments, the column body 21 is a hollow structure. With the above arrangement, the weight of the column body 21 can be reduced, which is convenient for rapid turnover during use and reduces labor intensity. Moreover, by providing the first sealing plate 22 and the second sealing plate 23, while being able to seal the column body 21, it is convenient to arrange the eyelet 26 and the docking assembly.
[0040] In some embodiments, the docking assembly includes two ear plates 24 arranged oppositely at intervals and two anti-toppling plates 25 arranged oppositely at intervals. The ear plates 24 and the anti-toppling plates 25 enclose an installation cavity, and the eyebolt 1 is located in the installation cavity, and a fastener is passed through the ear plates 24 and the eyebolt 1. By using the fastener to pass through the ear plates 24 and the eyebolt 1, the connection between the column body 21 and the eyebolt 1 is realized. By providing the anti-toppling plates 25, the rotation of the column body 21 relative to the eyebolt 1 is limited, so that the column body 21 is in a vertical state. Moreover, the connection between the docking assembly and the eyebolt 1 is realized by using the fastener, which is convenient for installation and disassembly.
[0041] In some embodiments, the fastener includes a bolt 3 and a locking tongue 31. The locking tongue 31 is rotatably arranged at one end of the bolt 3. The bolt 3 passes through the ear plate 24 and the eye plate 1, and the locking tongue 31 protrudes relative to the ear plate 24. Through the above arrangement, after the locking tongue 31 protrudes relative to the ear plate 24, the locking tongue 31 droops to limit the movement of the bolt 3 and prevent the bolt 3 from falling out of the ear plate 24 and the eye plate 1. While ensuring easy assembly, it can ensure that after installing the fastener, the column body 21 is stably connected to the eye plate 1 through the docking assembly.
[0042] In some embodiments, the distance between the two ear plates 24 is greater than the thickness of the eye plate 1. Through the above arrangement, it is convenient for the ear plate 24 to cooperate with the eye plate 1.
[0043] In some embodiments, the height of the eye plate 1 is less than the distance from the bottom plate 110 of the cargo hatch cover 100 to the hatch coaming panel 200. By limiting the height of the eye plate 1, it is possible to avoid structural interference between the cargo hatch cover 100 and the eye plate 1 during subsequent installation of the cargo hatch cover 100. Thus, when installing the cargo hatch cover 100 subsequently, there is no need to remove the eye plate 1, reducing the labor intensity and ensuring the smooth progress of shipbuilding work.
[0044] In some embodiments, the eye plate 1 is located between the hatch coaming wall plate 300 and the rubber pressing plate 120 for installing the cargo hatch cover 100. By defining the installation position of the eye plate 1 on the hatch coaming panel 200, it is possible to avoid structural interference between the rubber pressing plate 120 and the eye plate 1 during subsequent installation of the cargo hatch cover 100. Thus, when installing the cargo hatch cover 100 subsequently, there is no need to remove the eye plate 1, reducing the labor intensity and ensuring the smooth progress of shipbuilding work.
[0045] In some embodiments, the arresting cable assembly 4 includes a first steel wire rope 41, and first locking clips 42 are arranged at both ends of the first steel wire rope 41. The first locking clips 42 are connected to the eye loop 26. By using the locking clips to connect with the eye loop 26, it is convenient for quick installation or disassembly. Using the first steel wire rope 41 can cover a long distance and can play a good role in blocking.
[0046] In some embodiments, the hatch coaming safety guardrail device further includes a maintenance assembly 5. The maintenance assembly 5 includes a shackle 51, a second steel wire rope 52 and a maintenance gangway 53 connected in sequence. The shackle 51 is connected to the eye plate 1. By providing the maintenance assembly 5, the eye plate 1 can be fully utilized. When subsequent maintenance of the cargo hold is required, only the shackle 51 needs to be installed on the eye plate 1, and the maintenance gangway 53 is located in the cargo hold, and the crew can perform maintenance on the cargo hold through the maintenance gangway 53.
[0047] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
