Description

Technical Field

[0001] The present invention relates to the technical field of the installation of lashing bridges on container ships, and more particularly, to a deformation prevention tooling for a lashing bridge platform of a container ship. Background Art

[0002] Currently, the lashing bridge structure popular in the industry has multiple lashing platforms, and railing guards are arranged on both sides of the lashing platforms. In conventional designs, the lashing platforms are mostly a continuous whole. However, considering the convenience of lashing operation personnel to board the bridge, several discontinuities are usually added to the lowest platform, and boarding platforms are arranged at the discontinuities. Therefore, there are multiple free ends on the lowest platform. In the final state of the completed container ship, the free ends of the platform are fixed to the main hull through structures such as railing columns, and the state is firm and stable. However, during the construction, transportation, and installation processes, due to the weak structural strength of the platform and the lack of substantial support points, auxiliary strengthening structures need to be added to prevent deformation.

[0003] Currently, the common deformation prevention auxiliary strengthening structures are mainly in the form of welding, and the materials used are mostly angle steels. The implementation method is to weld the angle steels to both sides of the upper and lower platforms, and fix the free ends of the lower platform through the upper continuous platform to achieve the effect of preventing deformation. This method mainly has the following disadvantages: 1. Low disassembly efficiency: Since the auxiliary strengthening structure is a temporary structure, it needs to be cut off after the lashing bridge is installed, which involves hot work and damages the structure painting. After disassembly, painting work needs to be carried out for repair; 2. Material waste: The auxiliary strengthening structure requires additional materials, and there is loss to the auxiliary strengthening structure itself during the cutting process, and it cannot be guaranteed to be reused; 3. Difficult layout of the auxiliary strengthening structure: Affected by the form of the platform itself and the surrounding structures (railings), the layout space of the auxiliary strengthening structure is limited and it is difficult to layout; 4. Limited deformation prevention effect: The bilateral arrangement of the auxiliary strengthening structure has a good vertical deformation prevention effect, but a poor horizontal deformation prevention effect; 5. There are safety hazards during the removal process: Such auxiliary strengthening structures are mostly arranged outside the platform, and there is a risk of falling objects from a height during the removal process.

[0004] Therefore, it is very necessary to invent a deformation prevention tooling for a container ship lashing bridge platform that is flexible to disassemble, safe, and reusable. Summary of the Invention

[0029] As Figures 1 to 6 shown, an anti-deformation tooling for a lashing bridge platform of a container ship according to an embodiment of the present invention includes a fastening device and a rigid connecting rod. The fastening device includes an upper fastener 2 and a lower fastener 1. Eye plates are provided above the upper fastener and below the lower fastener. A plurality of fastening devices formed by connecting the upper fastener and the lower fastener are fixed to the edges of the upper platform and the lower platform of the lashing bridge platform. Hooks are provided at the ends of the rigid connecting rod, and the free end provided on the lower platform is connected to the fastening device on the upper platform through the hooks. In this embodiment, the device connecting the upper platform and the lower platform includes 4 groups of fastening devices and 2 groups of rigid connecting rods.

[0030] Further, the lower fastener includes a connected lower cross plate and a lower vertical plate. At least two bolt holes for bolts to pass through are formed in the lower vertical plate as fastening bolt holes, and an eye plate is provided below the lower cross plate; the upper fastener includes a sequentially connected upper cross plate, an inclined plate and an upper vertical plate. A long circular hole is formed in the upper vertical plate, and the aperture and position are matched with those of the lower fastener. An eye plate is provided above the upper cross plate. The device is fastened to the edge of the lashing bridge through a fastening bolt 3, a fastening spring washer 6 and a fastening nut 4. The purpose of setting the long circular hole is to flexibly adjust the relative positions of the upper and lower sheets according to different plate thicknesses of the lashing bridge platform to meet the usage requirements of platforms with different plate thicknesses. In addition, the provided long circular hole enables the device to be not affected by the plate thickness of the lashing bridge platform of the container ship and is applicable to lashing bridge platforms with various plate thicknesses.

[0031] Further, the lower vertical plate is vertically connected to the lower horizontal plate; the inclined plate is assembled at a 45-degree angle with the upper horizontal plate and the upper vertical plate. By setting the 45-degree angle assembly, the chamfer of the lashing bridge platform can be avoided.

[0032] Further, the fastening device further includes an adjusting gasket 5. The adjusting gasket is an independent rectangular plate with a circular hole in the middle. The plate thickness is selected according to the thickness of the lashing bridge platform plate and is placed between the lower fastener and the upper fastener during the locking process of the fastening device. The provided adjusting gasket can effectively avoid the situation that the upper and lower pieces do not fit tightly during the locking process. The purpose of having a circular hole in the middle is to prevent falling off and eliminate potential safety hazards.

[0033] Further, the fastening device further includes an anti-slip bolt 7. A screw hole for the anti-slip bolt to pass through is provided on the upper fastener. By further locking the entire device with the anti-slip bolt, the device can be effectively prevented from sliding along the lashing bridge platform. During the installation process, the bottom of the anti-slip bolt abuts against the lower fastener and is fixed by extrusion.

[0034] Further, the rigid connecting rod includes a fixed hook 9, a connecting pipe 8, a semi-fixed rotatable thread lock 10, a screw rod connecting hook 12, and a locking nut 11. The fixed hook is welded to the connecting pipe. The semi-fixed rotatable thread lock is connected to the connecting pipe. By using the lock in cooperation with the screw rod connecting hook, the length of the rigid connecting rod can be adjusted. After the length adjustment of the connecting rod is completed, it is fixed by the locking nut.

[0035] In this embodiment, the connecting pipe is a circular steel pipe. The purpose of this design shape is to facilitate the disassembly of the anti-deformation connecting rod in the ship-formed state (in the ship-formed state, this hook is located at a high point and the disassembly operation is restricted). The circular steel pipe is the main part of the rigid connecting rod. The steel pipe has good anti-deformation properties. Therefore, the present invention uses a circular pipe as the main body of the rigid connecting rod. The semi-fixed rotatable thread lock is connected to the main circular steel pipe. By using the lock in cooperation with the screw rod connecting hook, the length of the rigid connecting rod can be adjusted, and an appropriate length can be adjusted according to the distance between the upper and lower platforms. After the length adjustment of the connecting rod 13 is completed, it is fixed by the locking nut to prevent the segment from loosening during transportation and affecting the anti-deformation effect.

[0036] As a specific implementation method, the upper end of the rigid connecting rod adopts a "7"-type easily detachable hook, which is convenient for disassembly operations. The lower end of the rigid connecting rod adopts a semi-fixed rotatable thread lock, which can reduce the number of assembly units and is convenient for disassembly and storage.

[0037] Based on the structural characteristics of the lashing bridge platform of a container ship, the present invention designs a brand-new operation plan, which has the characteristics of simple assembly, recyclability, energy conservation and environmental protection, and can greatly improve the operation efficiency and effect of preventing deformation of the lashing bridge platform of a container ship. The present invention uses a rigid connecting rod to produce an anti-deformation effect, which can effectively prevent the lashing bridge platform of a container ship from deforming upward, downward, left and right during the construction and transportation process, and has a good anti-deformation effect.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
