Post, rudder stock and rudderpost decompose.Part dismounting to be decomposed in the top half of rudder for ship system, i.e. water surface upper deck, premise
Will be kept completely separate with the rudder blade of its underwater portion and rudderpost.Existing method is required for boats and ships entrance dock water-break and carries out, and
And bottom mechanism will be fixed, such as: with steel cable binding bottom rudder blade, then steel cable bundle after the stern side of a ship tightens up consolidate
Being scheduled on the tail side of a ship, carry out not tight rudderpost with this, the most just can carry out the maintenance work on top, there is bigger landing wind in this way
Danger, and limited by region, add maintenance workload, waste time and energy, inefficiency, cause maintenance duration to extend, to boats and ships
Normal work influence bigger.
Utility model content
The purpose of this utility model is for drawbacks described above of the prior art, it is provided that a kind of simple in construction, operation side
Just, in not water-break or without the fixing just operable rudder for ship leaf in bottom and rudder arm maintenance special purpose device.
For realizing above-mentioned utility model purpose, this utility model adopts the technical scheme that a kind of rudder for ship leaf and rudder arm
The maintenance special purpose device of method for maintaining, this maintenance special purpose device includes: main component, the first cross bar, the second cross bar and screw element,
Wherein, described main component is that strip is cylindrical；Described first cross bar is mutually perpendicular to connect with main component；Described second cross bar and master
Body part is mutually perpendicular to connect, and is positioned at below the first cross bar；Described screw element is fixedly installed on the lower surface of main component.
Additionally, this utility model also provides for following attached technical scheme:
Described main component is hollow seamless steel pipe, and its external diameter is slightly less than the diameter of rudder blade axle.
Described first cross bar is positioned at the lower surface of described main component up at 2/3, and described second cross bar is positioned at described main body
The lower surface of part is up at 1/3.
Described first cross bar and described second cross bar are mutually perpendicular to.
Described screw element is full silk bolt, and it is fixedly connected with each other with described main component by welding manner, and this screw element can be with
The locking screw of rudder for ship rachis mutually connects.
Compared to prior art, advantage of the present utility model is: simple in construction, cheap, will be main by screw element
Body part is fixed in the fixing threaded hole of rudder blade axle, then replaces stress by the first cross bar and the second cross bar, it is possible to by rudder blade
Being taken out by arm board and rudder bearer etc. on axle is changed or maintenance, thus avoids workboat and keep in repair every time and maintain rudder system and be required for
Enter that dock is anhydrous carries out, i.e. also can complete when not water-break, not by region, time effects, shorten the duration, save maintenance
Cost, and can effectively avoid rudder blade landing to damage.
Accompanying drawing explanation
Fig. 1 is rudder for ship leaf of the present utility model and the structural representation of rudder arm maintenance special purpose device.
Detailed description of the invention
Below in conjunction with preferred embodiment and accompanying drawing thereof technical solutions of the utility model are made further nonrestrictive in detail
Explanation.
See that Fig. 1, rudder for ship leaf of the present utility model and rudder arm maintenance special purpose device include main component the 1, first cross bar 2, second
Cross bar 3 and screw element 4.Main component 1 is cylindrical in strip, and its external diameter is slightly less than the diameter of rudder blade axle, this main component 1 from lower toward
On 2/3 at and 1/3 at be respectively provided with through hole, this two through hole radially extending along main component 1, and being mutually perpendicular to.First
Cross bar 2 and the second cross bar 3 are all cylindrical in strip, and radius is identical, and length is identical, insert in above-mentioned two through hole respectively, therefore
First cross bar 2 and the second cross bar 3 are mutually perpendicular to.Screw element 4 is fixedly connected on the lower surface of main component 1 by welding manner, its
In cylinder, and outer wall is provided with screw thread, can connect with the mutual screw thread of locking screw of rudder for ship rachis.
In the present embodiment, main component 1 uses hollow seamless steel pipe, uses hollow seamless steel pipe to be conducive to drawing materials conveniently, and
And lighter in weight.First cross bar 2 and the second cross bar 3 use solid round steel, and its bending resistance torsional strength is big, are beneficial to apply it greatly
Power.Screw element 4 uses full silk bolt.
The using method of rudder for ship leaf of the present utility model and rudder arm maintenance special purpose device is as follows:
1, first take out rudderpost centre-lock bolt, the screw element 4 of instrument of the present utility model screwed in locking screw,
And tighten fixing；
2, the first cross bar 2 is inserted in main component 1, then pass through jack or crowntree at boat deck and the first cross bar 2
Between hold out against, stopper, and fixation, now the first cross bar 2 has been in stress, the fixing nut of dismountable rudderpost, is subject to
Arm board, bearing etc.；
3, when the fixing nut of rudderpost, by arm board, bearing etc. through time on main component 1 to the second cross bar 3, by second
Cross bar 3 inserts in main component 1, holds out against with jack or crowntree, stoppers fixed equally, and at this moment the second cross bar 3 is in
Stress, i.e. can be taken off the first cross bar 2, takes out each maintenance part, by stress cross bar 3,4 the most alternately and repeatedly stress i.e. up to
Purpose is changed to maintenance.
4, dress is returned in like manner.
In sum, rudder for ship leaf of the present utility model and rudder arm maintenance special purpose device simple in construction, cheap, and pass through
Main component 1 is fixed in the fixing threaded hole of rudder blade axle by screw element 4, is then alternately subject to by the first cross bar 2 and the second cross bar 3
Power, it is possible to being taken out by arm board and rudder bearer etc. on rudder blade axle is changed or maintenance, thus avoids workboat and keep in repair every time
It is required for entering that dock is anhydrous carries out with maintenance rudder system, i.e. also can complete when not water-break, not by region, time effects, shorten
Duration, save maintenance cost, and can effectively avoid rudder blade landing to damage.
It is pointed out that above-mentioned preferred embodiment only illustrates technology of the present utility model design and feature, its purpose
It is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, this reality can not be limited with this
