The device is an integrated part of the steering engine and comprises a top cover (6) for the steering engine having an integrated hydraulic cylinder (10), wherein the hydraulic cylinder further comprises a hydraulic piston (12), at least one supply channel (13) for hydraulic oil, and at least one fastening-/adjusting device (11).
Description
Technical field
The present invention relates to a kind of device, and a kind of method of the rudder stock on lifting ship, this device has the object of the inside consumable accessory safeguarding steering wheel as an integrated part of rudder for ship machine.
Background technology
The object of the invention is can to steering wheel, be more particularly that " orbiting vane " steering wheel (hereinafter called steering wheel) realizes necessary maintenance work, simple suitable compared to prior art of maintenance process.Representative steering wheel comprises whole top radial bearing and the rudder radial bearing of rudder system.Rudder stock on ship is realized radial fixing usually by 2,3 or 4 points, realize axial restraint by 1 point, wherein steering wheel can as axially mounting point (also referred to as rudder cod).In the maintenance and/or failure process of steering wheel, it is feasible for radially and axially locking rudder stock, and has two kinds of alternatives of locking rudder stock.Method 1: by being typically connected to rudder blade sheet from chain with it or cable, realize the fixing of rudder and rudder stock; Method 2: in the steering wheel installation process of shipyard, can realize the fixing of rudder stock by the device be directly installed to around rudder stock by using.In addition, also need to discharge rudder stock in practical operation, can realize replacing.
In first technology example of this area is disclosed in NO 302695 B1, and it comprises latching device, can be activated rudder stock is kept in axis and radial direction relative to ship structure, its replacement to the steering wheel of ship and keep in repair relevant.
Compared to the present invention, other other rudder systems also having GB 1409245 A and JP58008496 A to disclose in first technology of this area.
Be in the weak point of first technology, it does not have easy method to carry out lifting rudder stock to discharge the rudder cod in steering wheel, is easy to change to make it.
Method 1 needs the operation of consumes resources, Expenses Cost, time and manpower.In addition, need chosen position in 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 solves many deficiencies of method 1.But method 2 only can be radial or axially realize locking.So can not lifting rudder stock to make rudder cod discharge thus to realize replacement.
In order to lifting rotor, rudder and rudder stock are released or unload to make rudder cod and other consumable accessorys and can be replaced, need the corollary equipment for these parts and extra anchor point, so also need resource, expend time in and cost.
Summary of the invention
Therefore, the object of the invention is to, seek a kind of device making work simplification from rudder cod self lifting rudder stock, rudder and rotor, to enable consumable accessory to realize compared to the more simple mode of existing method replacing.By the feature defined in claims, the present invention can realize above-mentioned purpose.
Accompanying drawing explanation
Further, also the present invention will be described in detail with reference to accompanying drawing in conjunction with some embodiments, wherein:
Fig. 1 shows cross-sectional plane according to orbiting vane steering wheel of the present invention and inner side schematic diagram;
Fig. 2 is the schematic diagram of detail section A in Fig. 1; And
Fig. 3 is the schematic diagram of detail section B in Fig. 1.
Detailed description of the invention
Device shown in Fig. 1 is symmetrical around rotor center.Except details A and details B.Therefore, equivalent parts is only numbered in side.
In figs. 1 to 3, show the structure 1 on the top being positioned at rudder stock 2, wherein this top is equipped with the steering wheel be connected on the hull 3 of ship.This steering wheel comprises rotor case 4, the rotor 5 be connected on rudder stock, top cover 6, bottom 7, the hydraulic efficiency nut 8 with the clasp 9 removably installed and hydraulic actuating cylinder 10.
Hydraulic actuating cylinder 10 is connected to top cover 6 by fastening and/or control apparatus 11.In addition, hydraulic actuating cylinder 10 is equipped with hydraulic piston 12, and this hydraulic piston receives by the service duct 13 being connected to manual pump or hydraulic efficiency pressure system/propulsion source (not shown) the hydraulic pressure being positioned at side.
At least one top radial bearing of rudder stock 2 is arranged in steering wheel, here by the radial bearing 14 being arranged in top cover and be arranged in bottom radial bearing 15 representated by.In this embodiment, rudder cod 16 is arranged in bottom 7.
In the normal operation of steering wheel, all wt of rudder and rudder stock all rests on rudder cod 16, this is because do not have unnecessary clearance envelope between clasp 9 and hydraulic actuating cylinder 10.In order to rudder cod 16 can be changed and be arranged in radial bearing 15 or other consumable accessorys of bottom, must lifting rudder stock to realize removing of application force on bottom.Otherwise discharging tightening screw bottom 7 and rotor case 4 kept together will be more difficult, this is because the application force that rotor, rudder stock and rudder apply is larger.
In order to discharge rudder cod 16, rudder stock and rudder must realize abundant lifting, are removed to make the application force be applied on rudder cod.The relevant lift height of rudder and rudder cod is only a few tenths of millimeter, this is because bottom 7 and rudder cod 16 contact surface from rudder stock 2 is moved down and away from.
Hydraulic efficiency nut 8 is arranged on the top of rudder stock 2 and pins, to make nut 8, not have relative movement between rotor 4 and rudder stock 2.In the normal operation of rudder, between the clasp 9 on hydraulic efficiency nut and hydraulic actuating cylinder 10, there is less gap.In order to lifting rudder stock 2, don't fail to lifting hydraulic cylinder, and need to discharge fastening and/or control apparatus 11.
On hydraulic piston 12, apply pressure through service duct 13, hydraulic actuating cylinder 10 is inevitable is also collided by lifting the clasp 9 be positioned on hydraulic efficiency nut 8.Then, hydraulic actuating cylinder by 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.By maintaining the pressure in service duct 13, keep upright position until bottom 7 departs from from rotor case.Reduce the pressure in service duct 13 subsequently, then hydraulic actuating cylinder will fall to the top of top cover 6.
After the maintenance carrying out some necessity, carry out supercharging to service duct 13, to make rudder stock 2 realize lifting, bottom 7 is reinstalled to put in place.When pressure finally discharges from service duct 13, hydraulic actuating cylinder 10 will drop to the top of top cover 6 again, and the weight of rotor, rudder stock and rudder will drop on down rudderpost again on bearing.Terminating this operation by tightening fastening and/or control apparatus 11, covering to make hydraulic actuating cylinder 10 be fixed to.
