Description

A kind of device that is used for the rudder stock on the lifting ship
Technical field
The present invention relates to a kind of device, and a kind of method that is used for the rudder stock on the lifting ship, this device has the purpose of the inside consumable accessory of safeguarding steering wheel as an integrated part of rudder for ship machine.
Background technology
The objective of the invention is can be to steering wheel, more particularly is that " orbiting vane " steering wheel (hereinafter being referred to as steering wheel) is realized necessary maintenance work, and maintenance process is cooresponding simple than prior art.Representative steering wheel comprises the entire top radial bearing and the rudder radial bearing of rudder system.Rudder stock on the ship is realized radially fixing usually by 2,3 or 4 points, realize axial restraint by 1 point, and wherein steering wheel can be as axially mounting point (being also referred to as the rudder radial bearing).In the maintenance and/or failure process of steering wheel, it is feasible locking rudder stock radial and axially, and the alternative method of two kinds of locking rudder stocks is arranged.Method 1:, realize fixing of rudder and rudder stock by being typically connected to the rudder blade sheet from one's body chain or cable; Method 2: in the steering wheel installation process of shipyard, but through using direct mount to realize the fixing of rudder stock to the device around the rudder stock.It in addition, in practical operation, also need discharge rudder stock, so that can realize replacement.
An instance in the technology formerly of this area is able to disclose in NO 302695B1, and it comprises latching device, can be activated so that rudder stock is axially upwards keeping with the footpath with respect to the ship structure, and its replacement with the steering wheel of ship is relevant with maintenance.
Than the present invention, other rudder systems that formerly technological GB 1409245A of also having of other of this area and JP58008496A disclose.
Formerly the weak point of technology is, it does not have easy method to come the lifting rudder stock to discharge the rudder radial bearing in the steering wheel, so that it is easy to change.
Method 1 needs the operation of consumes resources, expends cost, time and manpower.In addition, need chosen position in the harbour or be positioned at hydrostatic.
Method 2 can be divided into two kinds of different modification 2a and 2b.Method 2a is a solution, and wherein latching device is installed on the deck of ship.Method 2b is a solution, and wherein latching device is installed to the bottom surface of steering wheel.Method 2 has solved many deficiencies of method 1.Yet method 2 only can be radially or is axially realized locking.Thereby so just can not so that discharging, the rudder radial bearing realize replacement by the lifting rudder stock.
So that rudder radial bearing and other consumable accessorys are released or unload and can be replaced, need be used for the corollary equipment of these parts and extra anchor point for lifting rotor, rudder and rudder stock, so also need resource, expend time in and cost.
Therefore summary of the invention the objective of the invention is to, and seeks a kind of making from the device of the work simplification of rudder radial bearing self lifting rudder stock, rudder and rotor, so that consumable accessory can be to realize replacement than the more simple mode of existing method.Through the characteristic that is limited in claims, the present invention can realize above-mentioned purpose.
Description of drawings
Further, will combine some embodiments and describe the present invention in detail with reference to accompanying drawing, wherein:
Fig. 1 shows according to the cross-sectional plane of orbiting vane steering wheel of the present invention and inboard scheme drawing;
Fig. 2 is the scheme drawing of detail section A among Fig. 1; And
Fig. 3 is the scheme drawing of detail section B among Fig. 1.
The specific embodiment
Device shown in Fig. 1 is around the rotor center symmetry.Except details A and the details B.Therefore, equivalent is only numbered in a side.
In Fig. 1 ~ 3, shown the structure 1 on the top that is positioned at rudder stock 2, wherein this top is equipped with the steering wheel on the hull 3 that is connected to ship.This steering wheel comprises rotor case 4, be connected to rotor 5, top cover 6, bottom 7 on the rudder stock, have the hydraulic efficiency nut 8 and the hydraulic actuating cylinder 10 of the clasp of removably installing 9.
Hydraulic actuating cylinder 10 is connected to top cover 6 through fastening and/or control apparatus 11.In addition, hydraulic actuating cylinder 10 is equipped with hydraulic piston 12, and this hydraulic piston receives the hydraulic pressure that is positioned at a side through the service duct 13 that is connected to manual pump or hydraulic efficiency pressure system/propulsion source (not shown).
At least one top radial bearing of rudder stock 2 is arranged in steering wheel, here by radial bearing that is arranged in top cover 14 and radial bearing 15 representatives that are arranged in bottom.In this embodiment, rudder radial bearing 16 is arranged in bottom 7.
Normally in service at steering wheel, all wt of rudder and rudder stock all rests on the rudder radial bearing 16, and this is because do not have unnecessary clearance envelope between clasp 9 and the hydraulic actuating cylinder 10.For radial bearing 15 or other consumable accessorys that can change rudder radial bearing 16 and be arranged in bottom, must lifting rudder stock removing with the application force on the realization bottom.Otherwise, discharging the tightening screw that bottom 7 and rotor case 4 are kept together and will compare difficulty, this is because the application force that rotor, rudder stock and rudder apply is bigger.
In order to discharge rudder radial bearing 16, rudder stock and rudder must be realized abundant lifting, so that the application force that is applied on the rudder radial bearing is able to remove.The relevant lift height of rudder and rudder radial bearing is merely ten/several millimeters, this be because bottom 7 will move down from the contact surface of rudder stock 2 with rudder radial bearing 16 and away from.
Hydraulic efficiency nut 8 is installed in the top of rudder stock 2 and pins, so that do not relatively move between nut 8, rotor 4 and the rudder stock 2.Normally in service at rudder has less clearance between clasp on the hydraulic efficiency nut 9 and hydraulic actuating cylinder 10.For lifting rudder stock 2, don't fail to lifting hydraulic cylinder, and need to discharge fastening and/or control apparatus 11.
Exert pressure on hydraulic piston 12 through service duct 13, hydraulic actuating cylinder 10 inevitable also collisions by lifting are positioned at the clasp 9 on the hydraulic efficiency nut 8.Then, hydraulic actuating cylinder with lifting rotor 4, rudder and rudder stock 2 to desired location, about 0.5 ~ 1.0mm.Reactive volt-amperes from rotor, rudder stock and rudder will be transferred to rotor case 4 from bottom 7, further to the hull of ship.Through keeping the pressure in the service duct 13, keep the upright position to break away from from rotor case until bottom 7.Reduce the pressure in the service duct 13 subsequently, hydraulic actuating cylinder will fall to the top of top cover 6 then.
After carrying out some necessary maintenances, service duct 13 is carried out supercharging, so that rudder stock 2 is realized lifting, bottom 7 is able to reinstall and puts in place.When pressure finally discharges from service duct 13, hydraulic actuating cylinder 10 will drop to the top of top cover 6 once more, and the weight of rotor, rudder stock and rudder will drop on the rudder radial bearing down once more.Through tightening fastening and/or control apparatus 11 finishes this operation,, hydraulic actuating cylinder 10 covers so that being fixed to.
