Abstract

The utility model relates to a rudder horn, which comprises a neck bearing seat, a dumb brace and a connecting arm, and is characterized in that the connecting arm is of a plate structure. The plate structure comprises an outer covering plate and an inner plate, the inner plate includes first transverse partitions and a first vertical partition, the outer covering plate is of a barrel structure longitudinally enclosing the inner plate, the lower end face of the barrel structure is welded on the dumb brace while one part of the upper end of the barrel structure is welded on the neck bearing seat, one end of each first transverse partition is connected onto the lateral surface of the neck bearing seat, the other end of each first transverse partition is connected with the inner side of the outer covering plate, the first vertical partition is vertically connected with the neck bearing seat and the dumb brace, and the upper end of the rudder horn is connected with a steering gear room platform block. By the aid of the connecting arm of the plate structure, the dead weight of the rudder horn is greatly reduced so that hoisting is facilitated. Besides, the rudder horn is connected with the steering gear room platform in a sectioned mode, so that subsection mounting of the rudder horn is facilitated, and the mounting precision is effectively improved.

Description

A kind of rudder horn

Technical field

The utility model relates to a kind of rudder horn.

Background technology

Rudder horn is the arm shape member of the supporting semi-spade rudder of boats and ships, is generally steel casting, is easy to moulding by casting, is easy to the dress weldering, is easy to stand up, be easy to controlled deformation.But for the rudder horn of large ship, steel casting is from great, and rudder horn is normally installed in the building berth construction phase; But building berth stage ship stern space is narrow and small, and hull structure is numerous, and construction environment is abominable, dress weldering difficulty is big; The required cycle is longer, and setting accuracy is restive.It is still immature that rudder horn is installed in domestic technique in segmentation, and not having other experiences can reference.

Summary of the invention

The utility model technical matters to be solved provides a kind of rudder horn, overcomes existing steel casting from great, is not easy to the shortcoming that segmentation is installed.

For solving the problems of the technologies described above, the utility model provides a kind of rudder horn, comprises lower rudder bearing, dumb brace and connecting arm, it is characterized in that, said connecting arm is a plate construction.

Said plate construction comprises skin plating and inner panel; Said inner panel comprises first cross wall, first vertical clapboard, and said skin plating is for vertically surrounding the tubular structure of said inner panel, and the lower surface of said tubular structure is welded on the said dumb brace; The part of upper end is welded on the said lower rudder bearing; One end of said first cross wall is connected said lower rudder bearing side, and it is inboard that the other end connects said skin plating, and said first vertical clapboard connects said lower rudder bearing, dumb brace up and down.

Said inner panel also comprises second cross wall, and said second cross wall is connected the inboard of said tubular structure.

Said inner panel also comprises second vertical clapboard, and said second vertical clapboard connects said first cross wall and said dumb brace respectively.

Said second vertical clapboard also connects said second cross wall.

More optimal, the upper end of said rudder horn connects the segmentation of steering engine room platform.Vertical keel of said steering engine room platform segmentation vertically connect on said lower rudder bearing and the said skin plating, and the horizontal ribbed horizontal welding respectively of said steering engine room platform segmentation is on said lower rudder bearing and said skin plating.

The rudder horn of the utility model has alleviated deadweight greatly owing to adopt the connecting arm of plate construction, is convenient to lifting.Simultaneously, rudder horn and the segmentation of steering engine room platform connect as one, and are convenient to the installation of rudder horn segmentation, have effectively improved setting accuracy.
