Embodiment 1

[0034] This embodiment provides an in-situ traversing and floating device for the stern structure of a ship, which includes a lower support structure, an upper support structure and a high support pipe 14, and the lower support structure includes a support base 1, a fixed sleeve 3, a fixed eye plate 5 and a base The fixed pulley 4, the support base 1 is rectangular, the fixed sleeve 3 is installed on the four end corners of the support base 1, the inside of the fixed sleeve 3 is provided with a supporting spring 2, and the fixed eye plate 5 is installed on the opposite side of the support base 1 On both sides, the fixed eye plate 5 is provided with a positioning hole, and a connecting pin is provided in the positioning hole. The upper support structure includes a support pipe base 10, a fixed pipe column, and a guide eye plate 7. The fixed pipe column and the guide eye plate 7 are welded to the bottom of the support pipe base 10. The fixed pipe column matches the fixed sleeve 3...

Embodiment 2

[0036] This embodiment provides a method for in-situ traversing and floating of the stern structure of a ship, which includes the following steps:

[0037] Step 1. Before the stern structure of the ship is mounted, install the in-situ traversing floating device on the stern support position, weld the support base 1 to the embedded parts on the ground of the dock, and embed the fixed pipe column 8 on the support pipe base 10 Into the fixed sleeve 3, pass through the fixed eye plate 5 and the guide eye plate 7 through the connecting shaft pin 6. At this moment, due to the active force of the supporting spring, the support pipe base 10 and the fixed pipe column 8 are in a suspended state.

[0038] Step 2: Ballast 5 tons of ballast iron on the base of the support tube to make the entire traversing and floating device in a compressed state, and use the latch to pass through the locking pin hole 9 on the side of the fixed pipe string 8 and the fixed sleeve 3, so that the entire The...

Abstract

The invention provides an in-situ transverse moving and floating device and method for a ship tail fin structure. The device comprises a lower-layer supporting structure, an upper-layer supporting structure and a high supporting pipe, the lower-layer supporting structure comprises a supporting base, a fixing sleeve, a fixing eye plate and a base fixed pulley; the fixed sleeves are mounted at four end corner parts of the supporting base; a back shore spring is arranged in the fixed sleeve; a positioning hole is formed in the fixed eye plate, and a connecting pin shaft is arranged in the positioning hole; the upper-layer supporting structure comprises a supporting pipe base, a fixed pipe column and a guide eye plate, and the fixed pipe column and the guide eye plate are welded to the bottom of the supporting pipe base; and the fixed pipe column is matched with the fixed sleeve; a long kidney-shaped hole is formed in the guide eye plate, the guide eye plate is matched with the fixed eye plate, and the high supporting pipe is welded to the supporting pipe base. The invention can solve the problem that the tail fin structure ship cannot be transversely moved out of the dock after floating due to the influence of high support; therefore the arrangement limitation of the ship type in the dock is relieved.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a floating device and method for in-situ lateral movement of a ship stern structure. Background technique [0002] In the process of ship construction, the floating and undocking of the ship is an indispensable step after the completion of the product. The ship with the stern structure needs to set up multiple high supports in the 50-meter-long area of ​​the stern due to its special structural characteristics. Ensure that its tail fin structure will not produce sinking deformation. After the ship floats, the top of the high support is the outer plate, propeller blade, rudder blade, etc. that are higher than the stern part, so the ship must complete a longitudinal movement of 50-70 meters in the dock before undocking to ensure the top of the high support Other dynamic displacements after undocking will not occur after collision with the hull. [0003] Therefore, there will...
