Description

Technical Field

[0001] The present invention relates to the technical field of floating platforms on water, and in particular to a modular floating platform connection device and a connection method. Background Art

[0002] A floating platform refers to a platform that floats on the water and can bear objects of a certain weight. It can be used as a floating dock to dock small and medium-sized boats. The platform can also be used as an auxiliary tool to maintain or repair ships, boat equipment and other watercraft. It can also help implement water operations and build floating platforms to assist other mechanical equipment operations. In the existing technology, floating platforms generally use an articulated connection method. This connection method has low rigidity and is mostly used for floating platform systems with longitudinal end-to-end connections. The strip-shaped steel pontoons have low rigidity and there is relative movement between the steel pontoons. When the floating platform needs to be spliced ​​in two dimensions to form a large-area, high-rigidity water platform in a plane, the traditional articulated connection method cannot achieve a large-area, high-rigidity water platform that is seamlessly assembled in a plane due to the presence of an articulated joint that protrudes from the boundary of the floating platform box. To this end, it is necessary to provide a modular floating platform connection device and connection method to solve the above problems. Summary of the Invention

[0003] The present invention aims to solve the deficiencies of the prior art and provides a modular floating platform connection device and a connection method.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a modular floating platform connection device, comprising:

[0010] Furthermore, the blade connector slot includes two bolt receiving plates, the top of the bolt receiving plate is fixedly connected to a limit bolt, and a receiving plate reinforcement plate is welded to the bottom of the bolt receiving plate. The bolt receiving plate and the receiving plate reinforcement plate are both welded to the side of the steel pontoon groove, and a limit rod is welded under the steel pontoon groove. Two limit rod reinforcement plates are sleeved on the outside of the limit rod, and the limit rod reinforcement plate is welded to the inner wall of the steel pontoon groove. The limit rods corresponding to the two adjacent steel pontoons are inserted into the limit groove, and the vertical steel plate is located between the two limit rod reinforcement plates. Circular holes are opened at the four corners of the horizontal steel plate, and the limit bolts corresponding to the two adjacent steel pontoons are inserted into the circular holes.

[0011] Furthermore, a cylindrical cavity is provided at the top of the threaded hole of the square connecting plate for accommodating the bolt cap of the bolt.

[0012] Furthermore, the distance between the two limit rod reinforcement plates is 2 mm greater than the thickened part of the vertical steel plate.

[0013] Furthermore, the depth of the cylindrical cavity is 1 to 2 mm greater than the height of the bolt cap of the bolt, and the diameter of the cylindrical cavity is 10 to 20 mm greater than the working diameter of the electric wrench.
