Description

Technical Field

[0001] The utility model relates to a quick cable-release hook device, belonging to the technical field of cable-release hooks. Background Art

[0002] The quick release hook is a special equipment installed in petrochemical docks for ship cable winding and mooring. It is an updated product of the traditional mooring bollard. Compared with the mooring bollard, it further improves the operational safety and labor intensity, and has become a necessary equipment for modern docks at home and abroad.

[0003] The cable release hook structure is mainly composed of two parts: a quick cable release hook and an electric winch. The electric winch is an optional part. The quick cable release hook uses the vertical axis as the rotation axis when rotating in the left and right directions. When loading and unloading ships of different tonnages at the dock, the angles brought by the cable release hook are different due to the different sizes of the ships. The angle of the cable release hook needs to be adjusted. If the vertical axis is severely corroded, it is difficult to adjust the angle, which affects the flexibility of the cable release hook in rotating left and right, affecting the operating efficiency. At present, the protection of the vertical axis is mostly through regular maintenance and rust removal.

[0004] After the vertical shaft of the cable hook is corroded, it is extremely difficult to disassemble. When disassembling the vertical shaft normally, after removing the vertical shaft clamping plate or the shaft end clamping plate, use a crowbar or other lever-type auxiliary tools to take the vertical shaft positioning slot as the force point to take out the vertical shaft; if rust occurs, the vertical shaft cannot be taken out by ordinary methods. First, it is necessary to use a rust remover to remove rust and separate the vertical shaft and the vertical shaft sleeve, and make a tooling, weld the tooling to the top of the vertical shaft, use a jack to support the tooling, and lift the vertical shaft out. If necessary, it is necessary to use fire to heat the connection between the vertical shaft and the sleeve. This method has many steps and involves special operations such as welding. It is time-consuming and labor-intensive, and still cannot guarantee that the vertical shaft can be smoothly lifted out, and the maintenance cost is high. Utility Model Content

[0011] Furthermore, the protective structure includes a protective cover and a protective base, the protective cover is buckled on the protective base, a positioning plate is provided at the lower part of the protective base, and the protective base is clamped on the upper surface of the base through the positioning plate.

[0012] The effect of adopting the above further solution is that the protective structure is clamped on the base through the positioning plate, which can not only completely cover and protect the shaft structure, but also stabilize the protective structure.

[0013] Furthermore, the positioning plate is fixed to the upper surface of the base by bolts.

[0014] The effect of adopting the above further solution is that the positioning plate is fixed to the upper surface of the base by bolts, thereby fixing the protective structure, which not only saves materials and space, but also further stabilizes the protective structure and ensures the protective effect of the protective structure on the shaft structure.

[0015] Furthermore, the protective base is sealed and connected to the base by welding or applying waterproof sealant.

[0016] The effect of adopting the above further solution is that, by welding or applying waterproof sealant, the sealing connection between the protective base and the base surface can be ensured to prevent rainwater or seawater from entering.

[0017] Furthermore, the inner wall of the protective cover is coated with grease, and the protective cover is sealed and fitted with the protective base.

[0018] The effect of adopting the above further solution is that grease is applied to the inner wall of the protective cover, and the protective cover is buckled on the protective base, so that the protective cover can fit closely with the protective base to ensure the waterproof effect of the protective structure.

[0019] Furthermore, the protective structure is made of 316 stainless steel or hot-dip galvanized steel plate or steel plate coated with an anti-corrosion layer.

[0020] The effect of adopting the above further solution is that the protective structure adopts anti-corrosion and anti-rust materials, ensuring the overall waterproof function of the entire protective structure.

[0021] Furthermore, the total thickness of the anti-corrosion layer of the steel plate coated with the anti-corrosion layer is not less than 300 μm, specifically: the zinc-rich primer layer thickness is not less than 100 μm, the epoxy micaceous iron intermediate paint layer thickness is not less than 100 μm, and the polyurethane topcoat layer thickness is not less than 100 μm.

[0022] The effect of adopting the above further scheme is to limit the thickness of the anti-corrosion coating and the type of paint used, further ensure the anti-corrosion function of the protective structure, increase the service life of the protective structure, and ensure the waterproof and rust-proof effect on the shaft structure.

[0031] The material of the protective structure 3 can also be 316L stainless steel or hot-dip galvanized steel plate and other corrosion-resistant materials, and the thickness is generally not less than 2 mm.

[0032] The protective structure 3 of the utility model has a simple structure. When in use, the protective base 5 is fixed to the upper surface of the base by screws, and then the protective structure 3 and the surface of the base are waterproofly sealed by welding or applying waterproof glue. At the same time, lubricating oil can be injected into the channel of the vertical shaft 1, so that the lubricating oil flows along the channel 7 and the flow groove 8 between the vertical shaft 1 and the sleeve 2, ensuring the flexibility of rotation between the vertical shaft 1 and the sleeve 2, and grease is applied to the inner wall of the protective cover 4 so that the protective cover 4 and the protective base 5 can be tightly buckled together, ensuring the overall waterproof effect of the protective structure 3, effectively avoiding the erosion of sea water or rainwater, thereby avoiding the rust of the vertical shaft 1 and the sleeve 2.

[0033] The utility model is conducive to extending the service life of the vertical shaft 1. Before the protective structure 3 is set, lubricating oil is injected monthly for lubrication and maintenance according to the maintenance manual of the cable hook. However, due to the erosion of rainwater and seawater, the lubricating oil channel is damaged, the lubricating oil cannot enter smoothly, and the normal maintenance effect cannot be achieved. The vertical shaft 1 needs to be disassembled for maintenance, which is difficult to disassemble. The service life of the vertical shaft 1 is less than 8 years. According to the actual rust situation, the service life of the vertical shaft 1 will reach the scrap condition in about 10 years. After adding the protective structure 3, under normal maintenance, the vertical shaft 1 can be ensured to be used for 50 years. After the protective structure 3 is installed, the hidden dangers of rainwater and seawater erosion are eliminated, the daily maintenance cost is saved, and the production operation efficiency is improved.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
