Towing protecting device for self-elevating platform

Abstract

A towing protecting device for a self-elevating platform comprises a protecting cover shell, a protecting cover internal supporting structure and a protecting device connecting device. The protectingcover shell is formed by pressing a whole steel plate and is in a basin shape with a planar middle part and a beveled periphery, and the plane is in arc transition with the bevel; the protecting coverinternal supporting structure is a truss structure with T-beams as the main body, the main T-beams are transversely arranged, the assistant T-beams are longitudinally arranged, all the T-beams are connected through welding, and the welding leg size is 8 mm; the towing protecting cover device is in welding connection with a main hull through four pieces of horizontal I-steel and two round tubes with an included angle of 38 degrees with the horizontal direction, the welding leg size is 6 mm, the I-steel is welded to reinforcing bars of planking at the stern of the main hull, four reinforcing toggle plates are arranged when each round tube is welded to the internal supporting structure, and the round tubes are welded to reinforcing bars of the planking at the stern of the main hull.

Description

technical field [0001] The invention relates to a protective device, in particular to a towing protective device for a self-elevating platform. Background technique [0002] Jack-up platforms often do not have power devices and cannot move by themselves. Therefore, when the jack-up platform needs to dock, undock or change the operating environment, it needs to be guided and assisted by a tugboat. However, the jack-up platform is often only equipped with special towing equipment on the bow. When the jack-up platform needs to pass through some areas where the water level changes rapidly, the tugboat that only relies on the towing equipment on the bow cannot quickly pass through such areas. For the purpose of the area, it is necessary to arrange tugs at the stern of the ship to push the platform quickly through such areas. If the tugboat directly pushes the stern of the platform, it is easy to cause damage to the structure of the stern of the platform and bring great harm to t...
