Vertical column locking mechanism 45 is symmetricly set on column 422 both sides, and the vertical column locking mechanism 45 of every side includes column system Motion block 451, braking crossbeam 452, a pair of braking cross beam movement guide rail 453 and brake cylinder 454, column brake block 451 is vertically solid It is scheduled on the vertical section 422-1 side of column 422, braking crossbeam 452 is supported on a pair of braking cross beam movement guide rail 453, one Braking cross beam movement guide rail 453 is fixed on the upside of longitudinal buoyancy aid 1.Brake cylinder 454 bottom surface is fixed on longitudinal buoyancy aid 1, system Dynamic cylinder piston rod 454-1 front end is hinged with the braking outer vertical side of crossbeam 452.During vertical column locking mechanism 45 locking column 422, The braking crossbeam 452 of column 422 both sides bears against on the column brake block 451 of column both sides so that holding ship to be repaired The sill 421 of oceangoing ship bottom will not move it is ensured that work safety.It is additionally provided with column descending spacing on the upside of column brake block 451 Block 455, when the present invention is in off working state, can make column 422 drop to lower limit position, now column descending spacing block Be resisted against on the upside of braking crossbeam 442 on the downside of in the of 455, brake cylinder piston rod 454-1 without stretching out, ship afterbody lifting beam elevator Structure 43 and vertical column locking mechanism 45 are in the unloading condition not consumed energy.
It is provided with repairing buoyancy tank 46, the enforcement shown in Fig. 2 in the waters that two longitudinal buoyancy aids 1 and horizontal buoyancy aid 2 enclose Example is the ship afterbody maintenance for the double oar of Twin Rudders, therefore is provided with two repairing buoyancy tanks 46, repairs buoyancy tank 46 periphery and passes through hawser 463 are connected with longitudinal buoyancy aid 1, repair and are respectively equipped with the straight trough 461 matching with rudder blade and airfoil shape and translot on buoyancy tank 46 462, after ship afterbody water outlet to be repaired, straight trough 461 blocks rudder blade, and translot 462 blocks propeller, is easy to rudder blade and propeller 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.
