Description

Technical Field

[0001] The invention relates to the technical field of fixing a ship shaft locking block, and in particular to a shaft locking block base and a design and installation method thereof. Background Art

[0002] LNG ships usually have two sets of propulsion systems with shaft locks. When one propulsion system fails and cannot operate, the other propulsion system can still operate normally. At this time, the tail water flow will generate torque on the non-operating propeller, which will rotate through the shaft system of the propulsion system and then be transmitted to the ship's diesel engine, which will have an adverse effect on the ship's diesel engine. In order to prevent the propeller and the main ship's diesel engine from rotating, a shaft lock device is set on the shaft system. One of the shaft lock devices is to lock the entire shaft system with a lock block. There are grooves in the circumferential direction of the shaft lock disk, and the lock block is located directly below the shaft system. The lock block is pushed in along the axis direction, and the lock block can be embedded in the groove to achieve the purpose of locking the shaft. However, the distance between the lock block and the inner bottom plate in the engine room is far, and the lock block cannot be directly fixed on the hull structure. If the lock block is directly fixed on the inner bottom plate, the torque generated by the rotation of the shaft lock disk will be transmitted to the inner bottom plate, causing local deformation of the inner bottom plate. Summary of the invention

[0006] Preferably, bolt holes for fixing locking blocks are provided on the plate surface of the first panel located between the first reinforcing plate and the second reinforcing plate and on the plate surface located between the third reinforcing plate and the fourth reinforcing plate.

[0007] Preferably, grooves are provided on the inner sides of the first fixing block and the second fixing block, a first wedge block is provided in the groove of the first fixing block, and a second wedge block is provided in the groove of the second fixing block.

[0008] Preferably, the first reinforcing plate, the second reinforcing plate, the third reinforcing plate, the fourth reinforcing plate and the first longitudinal plate are all trapezoidal plates.

[0009] A design and installation method for a shaft system lock block base, specifically comprising the following steps:

[0010] S1, the dimensions of the lock block base are designed during the ship design phase:

[0011] Determine the size of the first panel and the first longitudinal plate according to the size of the locking block, and then determine the position of the reinforcing rib plate vertically fixed between the second rib plate and the third rib plate adjacent to it according to the length of the first longitudinal plate and the spatial angle k between the second longitudinal plate and the second rib plate;

[0012] The length of the reinforcing plate is determined according to the distance between the first rib plate and the second rib plate, and the height of the reinforcing plate is determined according to the center height of the plunger hole located directly below the locking shaft disk and the height of the locking block;

[0013] S2, making a locking block base according to the designed locking block base size;

[0014] S3, the inner bottom plate segmented construction stage, the strengthening rib is vertically fixed at the corresponding position between the second rib and the third rib;

[0015] S4, during the docking stage or after the ship is launched, the assembled lock block base is welded and fixed to the inner bottom plate.

[0016] The beneficial effects of the present invention are:

[0017] 1.

At the same time, the torque applied to the fixing frame can also be transmitted to the inner bottom plate of the hull through the reinforcing plate, thereby reducing the torque load borne by the inner bottom plate of the hull.

[0019] 3.

The rib on the back side of the inner bottom plate can be used to strengthen the structure of the locking block base, further increasing its structural strength and anti-deformation ability. At the same time, the reinforcing rib can also strengthen the inner bottom plate, further reducing the torque load borne by the inner bottom plate of the hull, and avoiding deformation of the inner bottom plate.
