Description

Technical Field

[0001] The invention belongs to the technical field of dock equipment, and in particular relates to an aluminum alloy floating dock. Background Art

[0002] With the rapid development of water tourism, yacht industry and marine engineering, the demand for floating docks, as important facilities connecting land and water, has increased significantly. Traditional floating docks are mostly made of steel or wooden structures. Although they have certain load-bearing capacity, they have the following technical defects:

[0003] 1. Material defects

[0004] Steel structure: susceptible to seawater corrosion, requires frequent anti-corrosion maintenance, has a short service life, and has a large deadweight, requiring high buoyancy of the floats, which increases the overall cost.

[0005] Wooden structure: poor corrosion resistance, easy to rot after long-term immersion, low strength, difficult to withstand strong winds and waves or ship impacts, and high maintenance costs.

[0006] 2. Connection method problem

[0007] Welding or bolt punching connection: Traditional welding will cause thermal deformation and reduce material strength; bolt punching will weaken the main beam cross-section and form stress concentration points, which will easily cause cracks or breakage risks in long-term use.

[0008] Excessive structural rigidity: Fixed connections are difficult to adapt to water level fluctuations and are prone to structural deformation or fatigue damage of connectors due to tidal or wave effects.

[0009] 3. Insufficient functionality and scalability

[0010] Traditional terminals mostly adopt a single-frame design, lack modular expansion capabilities, and are difficult to adjust in size or layout according to demand.

[0011] Water and electricity pipelines are usually exposed or require additional protection, which not only affects the appearance but also increases the difficulty of installation and maintenance.

[0012] 4. Design limitations of the gangway and fixed columns

[0013] Most gangways are fixed and cannot adapt to changes in water levels, making it inconvenient for people to get on and off and posing a safety hazard.

[0014] The fixed columns are rigidly connected to the main beam, which can easily generate additional stress when the water level changes, affecting the stability of the dock.

[0015] Therefore, there is an urgent need for a floating dock that is lightweight, corrosion-resistant, has no punching connections, and can dynamically adapt to water level changes. Summary of the Invention

[0016] In view of the above deficiencies in the prior art, an object of the present invention is to provide an aluminum alloy floating dock.

The non-perforated main keel avoids the structural strength loss and corrosion problems that may be caused by traditional perforated connections, thereby improving the durability and reliability of the main keel. The various components, such as the panels, secondary keel, and pontoons, are connected by grooves. This connection method facilitates installation and disassembly, improves installation efficiency, and also facilitates subsequent maintenance and replacement.

[0024] Preferably, the main beam includes a transverse main beam and a longitudinal main beam connected horizontally and vertically, the transverse main beam and the longitudinal main beam are connected by a frame connecting rubber block, the cross-section of the secondary keel is "C"-shaped, and a pair of oppositely arranged secondary keels are provided at the connection between the transverse main beam and the longitudinal main beam, the frame connecting rubber block is located in the cavity formed by the oppositely arranged secondary keels, the pair of oppositely arranged secondary keels are connected with bolts, the head of the bolt is clamped in the fifth clamping groove, and the bolt can slide in the fifth clamping groove, thereby realizing the relative position adjustment of the transverse main beam and the longitudinal main beam.
