Replacing and maintenance.
Below with the work process of the embodiment explanation present invention of the tail undercarriage maintenance of the Changjiang river carrier:
Longitudinal buoyancy aid 1 both sides inner width b=24m of the present invention, this Changjiang river carrier overall length=60.16m, molded breadth=19.00m,
Less than the 24m of inner width, can enter in the present invention.Ship weight 539t, within the scope of being in the present embodiment lifting, can be right in the present invention
This carrier is keeped in repair.Example of the present invention is fully loaded with work operating mode and absorbs water for 1.6m, and effective area is 1416.0344m.
Ship to be repaired passes through tugboat towage and pushing tow enters in the present invention, and its afterbody reaches the finger on sill 421
Positioning postpones, and the now drinking water of the present invention is 1.6m.Check column 422 both sides, confirm that column brake block 451 is in non-brake
Free state after, two crabs 435 can be started, the hoist rope 433 of each crab 435 passes through to correspond to
Angle pulley group 434, the fixed pulley group 431 under vertical door frame 41 and running block 432 is synchronous drives on corresponding column 422
Rise, drive ship afterbody to be repaired to rise so that sill 421 rises, the propeller of ship afterbody to be repaired and rudder blade go out
After water, ship afterbody lifting device 4 quits work.Then start vertical column locking mechanism 45, the brake cylinder of column 422 both sides is lived
Stopper rod 454-1 synchronously stretches out, promote respective braking crossbeam 452 mobile clamping column 422 both sides column brake block 451,
Ship afterbody lifting beam 42 is maintained at resting state, with hawser by ship's fix to be repaired in the present invention, finally two are repaiied
Reason buoyancy tank 46 moves to after straight trough 461 blocks rudder blade, translot 462 blocks the position of propeller, will repair buoyancy tank with several hawsers
46 are connected with longitudinal buoyancy aid 1 or horizontal buoyancy aid 2, and now, the maintainer on repairing buoyancy tank 46 can start maintenance vessel
The propeller of oceangoing ship afterbody and rudder blade.
The sequence of operation after maintenance terminates is contrary with aforementioned process, first releases the positioning hawser of ship, then column locking
Mechanism 45 unlocks, and then operating ship afterbody lifting beam elevating mechanism 43 makes sill 421 decline put in place, the ship after maintenance
Oceangoing ship afterbody is lowered to water and extremely finally can be dragged away the ship after keeping in repair with tugboat with operational configuration.
In addition to the implementation, the present invention can also have other embodiment, all employing equivalents or equivalent transformation shape
The technical scheme becoming, all falls within the protection domain of application claims.
