Definitions
- the present invention regards a device, and a method for raising a rudder stock on a ship, as an integrated part of the ships steering engine with the purpose of performing maintenance on the internal wearing parts of the steering engine.
- a representative steering engine contains the entire upper radial bearing of the rudder system and rudder radial bearing.
- a rudder stock on a ship is normally fasted radially at 2, 3 or 4 points and axially at one point, of which the steering engine can be the axial bearing point - also called rudder radial bearing.
- the steering engine can be the axial bearing point - also called rudder radial bearing.
- Method 1 in which the rudder and the rudder stock are secured by chains or cables that normally are fastened to the rudder blade itself; and Method 2, in which the rudder stock is secured by use of equipment mountable directly around the rudder stock during installation of the steering engine at the building yard. Furthermore, there a need in the field to relieve the rudder stock so that it can be replaced.
- NO 302695 Bl that comprises a locking device that may be activated to maintain a rudder stock axially and radially relative to the structure of the ship in connection with replacement or maintenance of a steering engine of a ship.
- Method 1 requires resource-demanding operations, both cost-wise, time-wise and personnel wise. Furthermore, it is assumed that the ship is situated in port or is located in calm waters.
- Method 2 can be split in two different variants 2a and 2b.
- Method 2a is a solution wherein a locking device is mounted on the deck of the ship.
- Method 2b is a solution wherein a locking device is mounted on the underside of the steering engine.
- Method 2 solves many of the disadvantages of method 1. However, method 2 is able to lock only radially and axially. It is not possible to raise the rudder stock so that the rudder radial bearing is relieved and thereby replaceable.
- the object of the present invention is therefore to find a device that ease the work of raising of the rudder stock, rudder and rotor from the rudder radial bearing itself so that the wearable parts can be replaced in an easier way compared to current methods.
- This object is achieved by the invention as they are defined in the stated features of the claims.
- figure 1 shows a schematic sketch of a rotary-vane steering engine according to the invention, cross-sectioned and in side view;
- figure 2 is a section of details A in figure 1 , and
- fig 3 is a section of details B in fig 1.
- the device shown in fig 1 is symmetrical around the centre of the rotor. Exceptions are detail A and detail B. Consequently, equal parts are numbered on one of the sides only.
- an arrangement 1 is shown on an upper part of a rudder stock 2, of which the upper part is equipped with a steering engine attached to the hull 3 of the ship.
- the steering engine comprises a rotor housing 4, a rotor 5 connected to the rudder stock, a top cover 6, a bottom cover 7, a hydraulic nut 8 with removably mounted retaining ring 9, and a hydraulic cylinder 10.
- the hydraulic cylinder 10 is attached to the top cover 6 using a fastening- / adjusting device 1 1.
- the hydraulic cylinder 10 is equipped with a hydraulic piston 12 receiving a hydraulic pressure on one side through a supply channel 13 connected to a manual pump or a hydraulic system / power source (not shown).
- the at least one upper radial bearing of the rudder stock 2 is located in the steering engine and is here represented by a radial bearing 14 in the top cover and a radial bearing 15 in the bottom cover.
- a rudder radial bearing 16 is located in the bottom cover 7.
- the hydraulic nut 8 is mounted on top of the rudder stock 2 and is locked so that there are no relative motions between the nut 8, rotor 4 and rudder stock 2. During normal operation of the rudder there are a small clearance between the retaining ring 9 on the hydraulic nut and the hydraulic cylinder 10. In order to lift the rudder stock 2 it is necessary to lift the hydraulic cylinder, and the fastener- /adjusting devices 1 1 are loosened to allow for this.
- the hydraulic cylinder 10 By applying pressure on the hydraulic piston 12 through the supply channel 13 the hydraulic cylinder 10 must be raised and collided with the retaining ring 9 on the hydraulic nut 8. The hydraulic cylinder would then raise rotor 4, rudder and rudder stock 2 to the desired position, about 0,5-1 ,0 mm. The reactive power from rotor, rudder stuck and rudder is then transferred from the bottom cover 7 to the rotor housing 4 and further to the hull of the ship. The vertical position is maintained by maintaining the pressure in the supply channel 13 until bottom cover 7 is detached from the rotor housing. Afterward the pressure in the supply channel 13 is reduced, after which the cylinder will be brought down to the top of the top cover 6.
- the supply channel 13 is pressurised so that the rudder stock 2 is raised and the bottom cover 7 can be remounted in place.
- the hydraulic cylinder 10 will once again be brought down on top of the top cover 6, and the weight of the rotor, rudder stock and rudder will again be brought down on the rudder radial bearing.
- the operation is ended by tightening up the fastening- / adjusting devices so that the hydraulic cylinder 10 is fastened to the cover.
