Technical Field

[0001] The utility model belongs to the technical field of shipbuilding, and particularly relates to an auxiliary device for under-frame operation of ship sections. Background Art

[0002] During the shipbuilding process, for the transportation of sections, after the section is built, it needs to be lifted onto a bracket 2.5m high. After being lifted onto the frame, there are still processes such as grinding and repair welding under the section. When personnel construct on the ground, the height is insufficient. Standing on ordinary ladders, there are the following problems: ① During construction, work is not carried out at the same point; ② The ladder is inconvenient to move, lacks safety protection, and there are potential safety hazards; ③ Due to the section having a hull form and different construction heights for the section, the ladder cannot be adjusted and is inconvenient to use.

[0003] In view of the above problems, it is necessary to study an auxiliary device for under-frame operation of ship sections, which can solve the problem of personnel constructing under the frame after the section is removed from the frame. Summary of the Utility Model

[0022] First of all, it should be noted that the following will specifically illustrate the specific structure, characteristics, advantages, etc. of the present utility model by way of examples. However, all descriptions are only for illustrative purposes and should not be construed as forming any limitation to the present utility model. In addition, for any single technical feature described or implied in each embodiment mentioned herein, any combination or deletion can still be carried out between these technical features (or their equivalents), so as to obtain more other embodiments of the present utility model that may not be directly mentioned herein.

[0023] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0024] As Figure 1-6 shown, the utility model provides an auxiliary device for underwater operation of ship sections, which includes a number of support columns connected by connecting columns to form a cuboid-shaped support body. At least three layers of platforms are sequentially arranged inside the support body from bottom to top. The platforms are supported and fixed by fixed pipes connected to the support body, and the platforms are sequentially arranged in a stepped-up structure;

[0025] A top platform is also provided at the top of the support body, and the top platform does not block other platforms below in the vertical direction. It can also be further considered that the top platform and the platforms below are respectively arranged on different horizontal planes inside the support body, forming a height difference and having no overlap in the vertical direction.

[0026] Specifically, as Figure 1 、 2 shown, the support body A in this embodiment includes 4 support columns 1. The lower parts of the support columns are connected by four first connecting columns 2, and the tops of the support columns are connected by three second connecting columns 3, so that the support body forms a cuboid shape; inside the cuboid-shaped support body, a first platform 4, a second platform 5, and a third platform 6 are sequentially arranged from bottom to top. The first platform 4, the second platform 5, and the third platform 6 are sequentially arranged in a stepped structure. And for the convenience of climbing and using the auxiliary device, it can be considered that the first platform is arranged below the top of the support column where the second connecting column is not provided, and the first platform 4, the second platform 5, and the third platform 6 are all supported and fixed by fixed pipes 7 connected to the support body; a top platform 8 is also provided at the top of the support body, and the top platform does not block other platforms below in the vertical direction. In this embodiment, in the width direction of the support body, the top platform is respectively arranged with the second platform 5 and the third platform 6, so that the top platform 8 does not block the second platform 5 and the third platform 6 below in the vertical direction;

[0027] In addition, guardrails 9 are arranged on the top of the support body in three directions. In this embodiment, the guardrails are connected to the support body through hinges 14, and the guardrails in the three directions are connected to each other through bolts 10 and bolt sleeves 11. Among them, the bolt sleeves are welded on the guardrails. When the bolts are pulled out, the guardrails can be put down. When people stand above the auxiliary device, it belongs to high-altitude operation. The guardrails can effectively protect the safety of personnel and prevent them from falling from a height. After the guardrails are put down, the device can be pushed under the section for operation. After the guardrails are raised, when people stand on the high level, it can also play an effective protective role.

[0028] It should be noted that the top platform and the first platform 4, the second platform 5, and the third platform 6 below all adopt expanded metal sheets. When the staff stands on different working platforms, it can meet the construction operations at different heights as the height of the section varies.

[0029] At least two universal wheels 12 and at least two locking universal wheels 13 are installed at the bottom of the support body to enable the movement of the device and meet the operations at different points. At the same time, the locking wheels can effectively ensure that the device does not shake.

[0030] The device of this embodiment can be used for all under-tire operations after the tire is segmented. The height of the device is placed on the ground, and a platform is set above. Personnel stand on the platform to operate, so as to achieve the purpose of personnel standing on the device for construction after the tire is segmented.

[0031] The above embodiments have described the present invention in detail, but the described content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
