Abstract
The invention discloses a method for disassembling a stern tube bearing in a floating state of a ship. The method comprises the following steps of (1) adjusting a ship trim to enable the hub part of a tail rotor of a hull to break the surface of water; (2) erecting a scaffold; (3) removing hinge bolts connected with the front part and the rear part of an intermediate shaft; (4) lifting the intermediate shaft up, and laying up the intermediate shaft at the bottom plate of an engine room and fixing; (5) removing a cone, loosening a hydraulic nut on the tail rotor, and pressurizing the tail rotor in a radial direction by using a hydraulic pump until the tail rotor and a tail shaft are basically separated; (6) pulling out the tail shaft from the inside of the engine room; and (7) disassembling and repairing the stern tube bearing. According to the method for disassembling the stern tube bearing in the floating state of the ship, the construction is not limited by fields, the construction speed is increased, and the repair cost is saved.
Description
Technical field:
The present invention relates to the maintenance of the vessel field, relate in particular to a kind of ship floatation state tail tube bearing method for dismounting.
Background technology:
Boats and ships tail tube bearing occurs and damage and need open and inspect after navigation a period of time (not arriving the overhaul time again), and this work is generally carried out after dockage.Because it is longer that this changes the work period, if docking can improve repair cost on the one hand, also may be subjected to construction party to arrange depressed place phase period to influence on the other hand.If use dismounting worker method waterborne, then can accelerate speed of application, save general expenses most possibly and not limited by the place.
Summary of the invention:
The purpose of this invention is to provide a kind of construction and not limited by the place, improve speed of application, save the ship floatation state tail tube bearing method for dismounting of repair cost.
The present invention is achieved in that a kind of ship floatation state tail tube bearing method for dismounting, it is characterized in that may further comprise the steps:
(1) adjusting the boats and ships trim partly surfaces hull tail undercarriage propeller hub;
(2) set up scaffold;
(3) remove the preceding latter linked articulation bolt of jackshaft;
(4) jackshaft is upwards sling, be held on cabin base plate and fixing;
(5) remove army cap, unclamp the hydraulic nut on the screw, use hydraulic pump that screw is radially pressurizeed and throw off substantially until screw and tailing axle;
(6) in the cabin, tailing axle is pulled out;
(7) dismounting, maintenance tail tube bearing.
The present invention's construction is not limited by or not the place, has improved speed of application, has saved repair cost.
The specific embodiment:
A kind of ship floatation state tail tube bearing method for dismounting is characterized in that may further comprise the steps: (1) adjusts the boats and ships trim partly surfaces hull tail undercarriage propeller hub; (2) set up scaffold; (3) remove the preceding latter linked articulation bolt of jackshaft; (4) jackshaft is upwards sling, be held on cabin base plate and fixing; (5) remove army cap, unclamp the hydraulic nut on the screw, use hydraulic pump that screw is radially pressurizeed and throw off substantially until screw and tailing axle; (6) in the cabin, tailing axle is pulled out; (7) dismounting, maintenance tail tube bearing.During concrete enforcement, this method is applicable to opening and inspecting of screw, tailing axle and tail tube bearing under the ship floatation state.
